Giant Carbon Capturing Funnels in Southern Ocean





If you happen to be skeptical of climate modeling, this makes it a rout. A powerful nonlinear effect is dynamically responsible for injecting 40 % of the oceanic CO2 into the deep. Ignoring this is akin to ignoring tornadoes and we have just discovered it. The real problem is that we need a really good three dimensional dynamic model of the Ocean. From that it becomes plausible to model the overlying atmosphere. Perhaps one day we will be able to track and follow the heat.

Otherwise we naturally fall into the error of assuming the atmosphere is the dominant driver. A little like describing cooking and forgetting the role of the heat source. On Earth we have two heat sources. One is the sun and the other is the Ocean and to a far lesser degree the land surface.

That is the principle reason that I suspect that the key driver for the abrupt appearance of a little ice age happens to be an oceanic current flow transition of some sort. It would only need an inversion of cold water over the Gulf Stream for even a few years to wreak Europe and drop the average temperature by a couple of degrees. I can imagine it and we do not know if it is possible. More likely the real scenario will be a complete surprise.

Giant carbon-capturing funnels discovered in Southern Ocean

Aug 1, 2012



A team of scientists from the UK and Australia has shed new light on the mysterious mechanism by which the Southern Ocean sequesters carbon from the atmosphere. Winds, vast whirlpools and ocean currents interact to produce localized funnels up to 1000 km across, which plunge dissolved carbon into the deep ocean and lock it away for centuries. Critically, these processes themselves – and the Southern Ocean's ability to affect global warming caused by human activities – could be sensitive to climate variability in as-yet-unknown ways.

Oceans represent an important global carbon sink, absorbing 25% of annual man-made CO2 emissions and helping to slow the rate of climate change. The Southern Ocean in particular is known to be a significant oceanic sink, and accounts for 40% of all carbon entering the deep oceans. And yet, until now, no-one could quite work out how the carbon gets there from the surface waters.

"We thought wind was the major player," says lead author of the new study, Jean-Baptiste Sallée of the British Antarctic Survey. "The ocean is like an onion – in layers – and there is very little connection between the surface and deep layers," he explains. When strong winds displace a large slab of surface water and cause it to accumulate in a specific region, the localized bloat in the surface layer gets injected downwards into the ocean's interior. But this kind of wind action alone should have a fairly uniform effect over vast swathes of ocean – which is not what the scientists measured.

Subduction hotspots

Scrutinizing 10 years of temperature, salinity and pressure data from a fleet of 80 small robotic probes dotted around the remote Southern Ocean, the researchers discovered that surface waters are drawn down – or subducted – at a number of specific locations. This occurs due to the interplay between winds, dominant currents and circular currents known as "eddies". "You end up with a very particular regional structure for the injection of carbon," says Sallée, describing 1000 km-wide funnels that export carbon to the depths.

The team pinpointed five such zones in the Southern Ocean, including one off the southern tip of Chile and another to the south-west of New Zealand.Elsewhere, currents return carbon to the surface in a process known as "reventilation", but overall, the Southern Ocean is a net carbon sink.

Carbon bottleneck

The mechanisms governing atmosphere-to-ocean carbon transfer – the mechanical mixing action of wind and waves, and biological uptake by micro-organisms in the sunlit top layer of water – are already well understood. The step that determines the rate of the oceanic uptake of carbon, according to co-author of the study, Richard Matear of Australia's Commonwealth Scientific and Industrial Research Organization, is the physical transport of this dissolved carbon from the surface waters into the ocean interior. "Our study identifies these pathways for the first time," he says.

Understanding these subduction pathways fully is key to predicting how climate change might alter the Southern Ocean's carbon sequestering capabilities. Both global warming and the Antarctic ozone hole increase the temperature gradient between the equator and the pole, which intensifies the southern hemisphere winds. Climate models predict that stronger winds could stir up deep waters, especially in violent seas such as the Southern Ocean, and result in a net release of carbon back into the atmosphere.

"What we don't know yet is the impact of climate change on eddy formation," says Sallée. Eddies arise from oceanic instabilities caused by extreme gusts of wind, intense surface heating or cooling, or strong currents meeting uneven bottom topography, but tend to escape the granularity of even the most detailed climate models. "We can speculate that if wind increases, there will also be more eddies to counterbalance its effects," considers Sallée. "But it's a question we don't know how to answer yet. And it's a big incentive for climate models to refine their grid."

Improving climate models

Ocean-carbon-cycle expert Corinne Le Quéré, director of the Tyndall Centre for Climate Change Research, UK, who was not involved in the study, echoes Sallée's call for improved understanding of wind-eddy interplay. "Southern Ocean winds have increased in the past 15 years in response to the depletion of stratospheric ozone," she explains, adding "There's a lot of discussion right now about how [wind-induced changes] are then counterbalanced by changes in eddies."

Because of this, today's climate models diverge when it comes to predicting the future carbon sequestration response of the Southern Ocean. "I think this [paper] is really the first time that we have such small-scale resolution in the exchange of carbon in the ocean from observation directly," says Le Quéré. "The natural next step will be to take climate models and see how well they're performing spatially and [temporally]...this study can really help constrain which are the good models."

Malaria Breakthrough





This is great news because it suggests that a vaccine can be manufactured that through multiple applications will confer real immunity.  There are presently convincing strategies out there able to slash populations of the mosquito but there will always remain reservoirs of infection waiting to bite.  Thus those who must accept exposure do need a true immunization protocol.

Otherwise I am growing optimistic that the various strategies presently been implemented particularly including simple nets will succeed in driving this scourge out of humanities life way.

We have continued to note continued and expanding progress over the past five years of this blog.

Malaria breakthrough by Australian researchers


Scientists in Australiasay they’ve made a breakthrough in the fight against malaria by uncovering a key protein in people who have developed an immunity to the disease.

Researchers at Melbourne’s Burnet Institute analyzed the antibodies of adults and children in Kenyawho had become immune over time to the parasite, carried by mosquitoes.

James Beeson, head of the institute’s Centre for Immunology and senior author of the study, said his team examined a key malaria protein called PfEMP1.

“The puzzle has been, what is the key point of attack of the immune system against malaria? We’ve established that one particular protein of malaria is the key point of attack of the immune system,” said Beeson.

Scientists discovered certain Kenyans had developed an immunity to that protein, which means the protein could be a target for a future vaccine.

Specifically, the team studied children between ages of one and 10, as well as adults, and the number of times they had gotten malaria. The more times they had suffered the disease, which causes up to a million deaths year, the more antibodies they had.

According to the study, “repeated infections over time are required to generate antibody responses toward [the protein].”

Beeson said new research will focus on developing a vaccine to induce that immune response to the protein.

Malaria is caused by a parasite called plasmodium, which is transmitted through the bites of infected mosquitoes. Symptoms of malaria include fever, headache and vomiting, and usually appear between 10 and 15 days after the bite.

When untreated, malaria can quickly become life-threatening by disrupting the blood supply to vital organs.

The study, published in the Journal of Clinical Investigation, also involved research by University of Melbourne and the Kenya Medical Research Institute.

Signs of a Romney Victory




This is not ever going to come from the media that willy-nilly propelled Mr Obama into the White house as the most unexamined candidate in history. It finally turned out that he was a classic Marxist liberal arts professor who followed that dream deep into his career and was molded accordingly. Most likely his wife balanced his check book.

Now he must run on his record and that record begins and ends with one salient reality. He ignored the housing crisis in every way shape and form. Even Hoover did not ignore the depression ill advised as his prescriptions were. Today we do know better and a lot could have been done as I spelled out myself four years ago. Today, that market only now is seeing its first signs of life.

In the meantime, this election is Mr Romney's to lose and I can not imagine quite how this could be accomplished. The analysis below truly shows just how daunting Obama's task has become. Usually elections are won or lost between two well matched candidates within one percentage point. Right now I suspect that the real spread out there exceeds five percent which can still be cloudy in the poling.

We are looking at a Reaganesque landslide in the making even if Obama is able to hang on to his core. The American people know who Mr Obama is today and they will simply not want another four years of his performance. Recall they are all getting the bill for Obama-care. Is anyone paying less?


The Signs of a Romney Victory

Posted by Evan Sayet on Jul 30th, 2012



As I study the news looking for clues as to who is going to win the White House in November, I am struck by how, no matter where I look – from the most obvious to the things only a political junkie finds under a rock or in some tea leaves, etc. – every single indicator (big and small) points to a Romney victory and, in fact, something awfully close to an electoral college landslide.  While I will, of course, discuss the polls, the vast majority of my analysis comes from observation and common sense.

Let’s first establish a baseline.  Mark Levin asked a room full of folks at the Ronald Reagan library recently, “Do any of you know a single person – even one – who didn’t vote for Obama in 2008 who plans to vote for him in 2012?”  The answer, of course, was “no.”  Not a single person in the room knew a single person who Obama had, in the course of his presidency, convinced that he was better than they’d expected him to be.  Conversely, we all know at least one person – and I personally know more than a dozen (because I ask) – who voted for Obama in 2008 who nothing less than rues the day.

Given that Obama’s 2008 victory was, while large in size, in no way numerically historic, and that he had all sorts of advantages (being a blank slate, following eight years of war after 9-11, etc.) that he won’t have this time, Obama’s chances for a second term are significantly lower based on just Levin’s observation alone.  But, for Obama, it gets worse.

Not only is the pool of potential Obama supporters way down from 2008, so too is the enthusiasm amongst those who still, to one degree or another, prefer Obama over the alternative.  Whereas, not all that long ago, Obama could pack football stadiums and basketball arenas with ease, not even the lure of attending the big campaign kick-off event was enough for Obama supporters to come, leaving the venue half-empty.  If you can’t get your supporters to an historic rally in the spring, there’s little chance they’re going to drive to the polls in the dead of winter.

Worse still for the President is that, in order for him to have pulled off his original victory, he needed unprecedented enthusiasm (manpower, money, votes and more) from a handful of the Democrat Party’s traditional constituencies such as blacks, Jews and those under twenty-five.  If these numbers were to simply return to normal, then Obama’s chances of a second term are only further diminished.  But logic and evidence suggests Obama’s support from these groups will be less – in some cases far less – than what any and all Democratic nominees can count on.  This is because, thanks to his policies, each of these constituencies has a specific and rightful grievance against this president.  These grievances not only dampen their enthusiasm for Obama but, in many cases, turn them against him.

Blacks, for example, particularly hard hit by the liberals’ fifty-year war against the traditional family, have taken singular exception to Obama’s clearly politically motivated endorsement of homosexual marriage; Jews are rightly concerned about the most virulently anti-Israel President since the Jew-hating Jimmy Carter, while the young who have (attempted) to enter the workforce are suffering the realities of looking for a job in an Obama economy and can’t be wholly unaware that each dollar of new deficit Obama racks up will be expected to be paid for by them.  Will Obama still take a majority – even a large majority – of votes from these constituencies?  Of course.  But in every way – manpower, financial contributions and votes – not only will Obama fail to receive record support as he did in 2008, or even the usual support a Democrat needs, he will fall short and even see some of that support drift to Romney.

There is one more constituency that Obama had to win – and win big – in order to win the White House in 2008 that is now not only less supportive but greatly disgruntled.

They are the independents (and even some right-of-center Republicans) who might well have disagreed with many of Obama’s policies and prescriptions but who were willing to accept four or eight years of an Obama presidency in exchange for the promise his rhetoric offered of a more civil America.  Higher taxes, more wasteful spending, they believed, were an acceptable price to pay for a “post-partisan” America and maybe even a “post-racial” United States.

After four years of the most viciously partisan presidency in anyone’s living memory and the most race-charged administration most of us can ever recall (not to mention the vile tactics so closely associated with Obama and his administration, which are named after his hometown, “The Chicago Way”), those who voted against their policy preferences to elect the guy with “hope” and “change” are and can be nothing less than disgusted with him.

The category pollsters use to measure this sentiment is called “likeability” (or “personal favorability”) and Obama’s rating in this category is plummeting. The only way that a failed president can win a second term is if the people like and trust him. According to the latest New York Times poll, Obama’s tactics have left him “favorable” to only about one out of every three voters (36 percent).

Other recently released data suggest that Obama is in big trouble as well.  Not the least of them is the Obama camp’s inability to get people to donate to their campaign.  Not all that long ago, a confident (arrogant?) Obama team was predicting so much support that they’d bring in more money than any other campaign in human history – over one billion dollars.  So far, not only has Obama not come close to being the greatest fundraiser in all of human history, he’s not even the top fundraiser in his two-man contest for the presidency.  In fact, he trails Romney’s financial support by a wide margin.

This is important not just because money is a plus in any campaign (though not nearly the plus that many make it out to be) but because it is a tangible action.  Answering the telephone and saying “yes” or “no” ten times to some stranger from a polling company doesn’t require much of a commitment.  People who donate to a campaign are likely to do even more for that campaign and they are almost guaranteed to do the one thing that matters most: vote.

And there is more evidence of an impending Romney victory to be found in how each camp is conducting its campaigns.  The strategies employed, the rhetoric chosen, all of these things reflect the campaign’s belief about where they stand at any given moment in the contest.

For example, it is simply a truism in politics that a candidate who believes he’s winning stays on the message that put him in the lead.  Those who believe they’re losing change their message until they find one they believe is a winner.  Romney has run almost the entire time on a single, compelling and positive message.  At its heart it’s something like “America is in economic dire straits.  I’ve made my fortune and my reputation saving big and complex things (the Olympics, major industries, etc.) from economic dire straits.  Vote for me and I’ll save America.”  Romney’s staying on that message makes clear that, at the very least, his own internal polling and other evidence has convinced his campaign that he’s winning.

Obama, on the other hand, seems to be premiering a new message just about every week or two. It’s a practice of the desperate not so delicately known as “Throwing sh-t against the wall hoping something sticks.” Clearly, then, the Obama camp’s inside information is telling them the same thing my analysis and Romney’s intelligence is telling us: their messages aren’t working and that they trailing in the election.

Making matters worse for the president is that, while Romney’s message is positive and promising, the tenor of Obama’s ever-changing messages has been singularly negative.  As a failed president, since he can’t run on his record, the only option available to him is to try and render the alternative so far beyond the pale that, no matter how bad Obama is, the alternative is just unacceptable.  In other words, the entirety of Obama’s message (whatever it is at the moment) is comprised not of words like “Vote for me because” but only “Vote against him because…”  Such an unrelenting campaign of negativity – the only option for Obama – only serves to further undermine the only thing that could possibly help him win: his “likeability.”  It’s a catch-22 from which Obama is unlikely to be able to escape.

Making matters worse still for the current president is that, in these ever-changing messages, Obama’s case against Romney has ranged from beneath the dignity of a president of the United States to beneath contempt to beneath sanity.

In a short time, then, the Obama team’s message went from “Vote against Romney because he once had a dog carrier built that attaches to the roof of his family car,” to “Vote against Romney because fifty years ago he engaged in a high school prank” to “Vote against Romney because he’s a successful businessman (and therefore probably a felon)” and so on.  If this is all he’s got – and apparently it’s all he’s got – start making plans to attend Romney’s inaugural.

But it’s even worse for Mr. Obama because, not only did these ludicrous attacks utterly fail to move the needle even the slightest in his direction, each and every one of them totally backfired.  Some, disastrously so.

For example, while no one cared about Romney putting his dog in a carrier on the roof of his car, it allowed Obama to become a laughing stock for happily admitting that he had, at least once, put a dog on the roof of his mouth.  And, while no one cared about a childhood prank Romney helped pull off a half-century ago, it did lead to questions about Obama’s admission inDreams From My Father that, at about that same age, he had shoved a young woman.  And while no one was up in arms about the fact that a wealthy man had investments in countries outside of America, it not only exposed the hypocrisy of the accusers when it turned out that virtually every Democratic senator and congressman had similar investments, but it raised questions about how so many supposed “public servants” had amassed the kind of money usually associated with titans of industry.

These failures all paled in comparison, however, to the utter fiasco that was Obama’s attempt to sell the message: “Vote against Romney because Republicans hate women.”  Given how audacious a statement this is — how horrible it would be if it were true and how despicable the accusation if it wasn’t — the people waited for the President of the United States to produce some evidence to support his claim.  When all Obama could produce was a woman named Sandra Fluke whose “proof” consisted of opposition to tax-payers picking up the tab for her condom use, the President’s credibility took a massive hit…and Fluke was soon jettisoned (anyone hear anything from or about her since?)

While the Obama camp quickly threw Ms. Fluke under the bus, they weren’t quite prepared to give up their effort to discredit Romney and all Republicans as “women haters.”  Soon – with great fanfare and (media-generated) publicity – they unveiled their masterpiece: an animated “everywoman” they named “Julia.”  The campaign soon became the stuff of pure mockery, doing nothing to help Obama’s chances in November.  In fact, while it did nothing to advance the phony narrative of Republicans as being “at war” against women, what it did was to expose the very real misogyny of the liberal movement.  While the storyline followed the feminist meme, “A woman needs a man like a fish needs a bicycle,” it also made clear that these liberals believe a woman desperately needs a nanny (state) to accomplish even the simplest of things in her life.

But even more telling about the state of the race than the ever-changing slanders that serve as Obama’s campaign themes, is who the messages are targeting.  The fact that, three-and-a-half years into his presidency, a Democrat is still desperately trying to scare single women into voting for him means that Obama’s internal polling must be telling him that he’d better take desperate measures just to shore up a constituency that should have been his from day one.

Similarly, this is the only possible explanation for Obama’s desperate ploy to suddenly end his “evolving” and embrace homosexual marriage.  It is hard to believe that after more than fifty years of life, twenty-five years in academia or as a professional speechifier and three-and-a-half years as president, he’d suddenly had an epiphany that couldn’t wait just a couple more weeks until after what some believe will be a very close election.  The only possible explanation for the timing of Obama’s announcement was that he needed to placate the LBGT community, and the only reason he’d need to placate them is because his polling showed he hadn’t even shored up their vote this late in the game.  If a liberal Democrat isn’t even sure of the support from the LGBT movement a few weeks before Election Day, chances are good he’ll be packing his bags come January.

Finally, more information can be gleaned from the choices the two camps are making in how they conduct their campaigns. While some aren’t thrilled with what they perceive to be Romney’s “play it safe” style, it does indicate that his internal information is telling him that he has a sizeable lead. Whether this “four-corner” approach is wise or not, time will tell.  Nonetheless, it does seem to be borne of the old adage, “Never kill a man who’s already committing suicide.”

Another indicator along those same lines is that, while Obama is spending every penny he takes in and then a full twenty percent more (in debt), Romney’s “burn rate” is about eighty percent, saving twenty cents of every dollar the way prudent people save for the possibility of a rainy day.  Obama’s spending every penny he can get his hands on as fast as he can get his hands on it seems to indicate his understanding that he needs to just survive July at any and all costs and deal with the future if he makes it.

And it’s not just Obama’s desperate attempts to buy his way back into contention that is telling, so too is just what his campaign is spending that money on.  Spending this much money on television ads in July shows a degree of desperation.  Spending this much money on paid staff seems to be an indication Obama is lacking for the support of volunteers and so on.

Finally, the most telling of all is how much Obama is spending on polling.  Polling to judge the state of the race in July is not much of an imperative, especially when there are so many free sources for this information (Rasmussen, Gallup, etc.)  Typically such polling is conducted at this time to test various campaign themes and messages.  Obama’s frantic spending on focus groups and other such polling indicates that he is desperately searching for a message that will work and that he hasn’t yet found one.

Believe it or not, there are many more clues pointing towards a Romney romp that I haven’t yet touched upon (the bounce he’ll receive from announcing his running mate, the fact that Obama won’t have his teleprompter if/when they debate, etc.)

But I’m already on page five and, well, no matter where I look, all I see is a Romney victory in November.  In fact, it looks like it might even be a romp.


Giant Sloth Life Way





As I have already posted, it appears that we may have a population of giant sloths in North America. It is an extraordinary creature and it appears to be solitary for now, but on the basis of less than half a dozen separate sightings, it is premature to make that statement. This last report posted two days ago was very important, not least because it once again provides an extensive collection of witness information. Their misfortune was that their cabin encroached directly on the territory of one of these creatures and they then triggered a response.

First though, this creature is extremely dangerous in quite the same way that a grizzly is dangerous when disturbed. It needs to be observed with great caution. There are not a lot of these around, but you can bet their population is growing and they will become more noticeable. Until now it has been easier to assume a bear has been encountered and anyone unlucky to cross their path likely failed to survive.

From my post the other day:

1 It is fully furred and the fur is comparable to a bear causing natural misidentification from a distance.

2 It is a large creature that approaches the size and bulk of the Sasquatch. It is able to take down large herbivores.

3 All limbs sport long cutting claws with gripping ability for tree work and proficient digging. This is a very dangerous creature, certainly as compared to a Sasquatch.

4 It travels on four legs but easily rotates to the erect stance when attacking or confronting anything.

5 It has a long snout and long fangs designed for tearing meat from game. I only have one report regarding fangs, but otherwise I still think the creature is normally a herbivore first in quite the same way as other sloths. It is quite possible that the giant sloth developed fangs in quite the same way as isolated populations of deer will develop fangs when ample game is available.

6 It stinks because fecal matter get caught in the fur and rots and the creature is possibly unable to easily groom itself in that location. Alternatively, the fur simply accumulates sweat and oils throughout the year.

In short, it is a killing machine from our nightmares that is wonderfully adapted to take to the trees when threatened and for gaining a perfect hide to stalk game.

Now what else did we learn here? It is actually quite a lot.

1 It tears game apart in what may be described as a killing frenzy. This makes it particularly dangerous.

2 It eats some of the game and then caches the rest by burying it. This explains its interest in grave yards were it is able to smell decomposing meat.

3 It easily excavates a earthen den to den up in when sleeping. Because sloths need a long time digest plant material, it will typically slip into a month long dormant stage to do this. It has a much lower metabolism that we expect. Yet to prosper when it is about, meat protein is likely necessary. Winter may make it mandatory as these creatures have been possibly noted in New Hampshire.

I will now make a major conjecture. Although fangs have been noted, the creature is poorly adapted for eating meat in other that gobbets torn of the carcass and also can only eat a small amount at one time. After all its metabolism is very slow. What it is able to do is eat maggots. Thus it creates individual caches of buried meat which is inevitably a breeding ground for maggots upon which the creature can feed. Thus we get the noted odor of dead meat around this creature.

I want to note that maggots feeding on a carcass will take on the taste of the meat it is eating. This happens to also be used by the Eskimos at least occasionally in emergencies and possibly more often when a cache of caribou is left far too long.

Thus we have a predator that needs to operate within a small hunting range that dens up most of the time and hugely extends the usefulness of a kill by exploiting the produced maggots.

It is also nocturnal as are most predators. Thus it will be dened up during the daytime and considering the reports on its home ground, most interlopers would become nervous and be scared of.

If one is hunting for such a creature, be certain to search up wind and look for the smell of dead meat. Never approach from the other direction. Way more important though, scout all trees around yourself from the top down. That is were it is most at home.

This creature has not been hunted or trapped because it is too much for a lone individual to tackle and this would be sensed by an experienced bush man who would shy off just as these reports make clear.


Other key quotations:

“several tales of a wolf like creature that stood on two legs that would come out of the thickets and attack their cattle and live stock. Day or night. A creature that was taller then an average man by well over a foot, nearly 7 foot tall, with thick long hair covering it's body, and a stench that matched that of some of the freshly open graves that were discovered now and then. This 'wolf man' left tracks like a barefoot man but where the toes should have been, instead were paw prints. The head was huge and wolf like in appearance, with an extra long snout, and uncanny long sharp incisors that glistened from the moon light with saliva, along with eyes that, "Radiated red, like one of the hottest fires in Hell', they'd say. It had long arms that ended with huge hands and long spindly fingers with long, pointed, dirt caked claws”

“had went down in the woods earlier that morning and found several pits dug and filled with animal bones and parts of carcasses along the path that led to the old sawmill that couldn't be explained. There were also holes dug in the sides of the bluff along the hills that over-looked the old mill that looked like deep caves, big enough for a man to hide in''


Megatheria’ muzzles provide clues to giant ground sloth diets


Posted by Brian Switek on May 10, 2010

The skeleton of Megatherium, as figured in William Buckland’s Geology and Mineralogy Considered With Reference to Natural Theology.



There is something fantastically weird about giant ground sloths. Creatures from a not-too-distant past, close enough in time that their hair and hide is sometimes found in circumstances of exceptional preservation, these creatures have no living equivalent. Their arboreal cousins still live in the tropics of the western hemisphere, but they can hardly be considered proxies for the ground sloths of the Pleistocene.

The most famous of these ancient beasts was Megatherium, an exceptionally large ground sloth which has been fascinating paleontologists and the public for over 200 years, but what is less well known by members of the public is that there were many kinds of ground sloth. Megatheriumwas not a lone aberration but a part of a highly successful family, one of the few types of weird South American mammal that flourished in North America when the two continents came into contact a few million years ago. Not all of them were the same. While some made their living grazing in open habitats others preferred to browse among most forested environs, and a recent study published in the Journal of Morphology provides a way to tell which kind of lifestyle particular sloths might have had.

Everybody knows that teeth can often tell you quite a bit about what an animal eats, but it is not the only informative parts of the skull when it comes to diet. To ascertain the range of dietary habits in giant ground sloths, researchers M. Susana Bargo, Nestor Toledo, and Sergio Vizcaino looked at the muzzle shapes of the species Megatherium americanum, Glossotherium robustum,Lestodon armatus, Mylodon darwini, and Scelidotherium leptocephalum, a selection with a variety of skull shapes. Two of these, Glossotherium and Lestodon, had squared-off muzzles, and the rest had more narrow snouts, but to determine how this related the diet the authors looked at the muscle scars and other landmarks in comparison with the known tissue anatomy of living sloths in an attempt to recreate the soft tissues of these animals.

As illustrated by the restorations of the head of each sloth, figuring out their muzzle shape was a multi-step process. First was determining the extent of nasal cartilage that would have been present in life. This provided the complete framework on which to place the various muscles related to lip movement, and from there the head could be fully fleshed out. Once these restorations were completed it could be further hypothesized whether each species was a browser or grazer, with grazers being characterized by having wide, squared-off muzzles suited to taking in low-quality foods (i.e. grass) in bulk and browsers having narrower muzzles better suited to more selective feeding on high-quality foods.

The results were fairly clear cut. Lestodon armatus and Glossotherium robustum both had comparatively wide, spoon-shaped muzzles, with Scelidotherium leptocephalum, Mylodon darwini, and Megatherium americanum having narrow muzzles (the latter species having the narrowest of all). Overlain on top of each other, there is a wide gap between the muzzle shape of the grazers and browsers; the sloths selected are not grades between one extreme and another but occupy opposite, well-defined ends of the spectrum. Additionally, Megatherium americanum may have been such a specialized feeder that it had a prehensile upper lip akin to what is seen in the black rhinoceros which it could have used to grasp and selectively tear off particular plant parts. The grazing sloths Lestodon and Glossotherium, on the other hand, would have had lips more like that of the white rhinoceros – squared off and better suited to bulk feeding.

The hypothesized feeding habits of these sloths are consistent with what is seen in living herbivores – browsers and selective feeders have narrower muzzles than grazers within lineages of plant-eating mammals. This may have been a form of niche partitioning as sloths evolved through the Pleistocene, and may explain why there were so many genera and species present at the same time. Even though we think of modern sloths as peculiar, specialized animals, the ground sloths of old appear to have been more adaptable to a wide array of habitats, though this makes their disappearance in relatively recent time all the more mysterious.
Post script: This kind of niche partitioning did not only exist between closely related species, but could also happen within species as organisms grew up. A recently-described juvenile Diplodocus skull, for instance, suggests that young individuals were browsers while adult Diplodocus were better suited to grazing.

From Crossbows to Cryptography With Chuck Hammill





 Consider that this article was written before the internet. Read it and you will discover just how prescient that it is. Also make the effort to grasp some of the mathematics described here. This is embedded in most of the data flow out there. This is why the internet will remain largely free and can only be stifled for a while here and there.

Of course the real protection comes from the mere mass of data. Today I could embed a message inside the library of congress and use this encryption technique to ship the data. While I am at it, I may as well use it to simultaneously send scads of messages with individually separate codings. Let us go crazy. The point is to swamp surveillance. That is why wire tap evidence crashed and burned as an effective tool. The courts found themselves obliged to listen to days of rubbish unrelated to the issue at hand in the event it may be pertinent. It makes perfectly good intelligence but challenging evidence by itself.

This item is well worth the read.




From Crossbows To Cryptography:

Techno-Thwarting The State

Chuck Hammill



Future of Freedom Conference, November 1987

Public Domain: Duplicate and Distribute Freely

You know, technology—and particularly computer technology—has often gotten a bad rap in Libertarian circles. We tend to think of Orwell’s 1984, or Terry Gilliam’s Brazil, or the proximity detectors keeping East Berlin’s slave/citizens on their own side of the border, or the sophisticated bugging devices Nixon used to harass those on his “enemies list.” Or, we recognize that for the price of a ticket on the Concorde we can fly at twice the speed of sound, but only if we first walk through a magnetometer run by a government policeman, and permit him to paw through our belongings if it beeps.

But I think that mind-set is a mistake. Before there were cattle prods, governments tortured their prisoners with clubs and rubber hoses. Before there were lasers for eavesdropping, governments used
binoculars and lip-readers. Though government certainly uses technology to oppress, the evil lies not in the tools but in the wielder of the tools.

In fact, technology represents one of the most promising avenues available for re-capturing our freedoms from those who have stolen them. By its very nature, it favors the bright (who can put it to use) over the dull (who cannot). It favors the adaptable (who are quick to see the merit of the new) over the sluggish (who cling to time-tested ways). And what two better words are there to describe government bureaucracy than “dull” and “sluggish”?

One of the clearest, classic triumphs of technology over tyranny I see is the invention of the man-portable crossbow. With it, an untrained peasant could now reliably and lethally engage a target out to fifty meters – even if that target were a mounted, chain-mailed knight. Unlike the longbow, which, admittedly was more powerful, and could get off more shots per unit time, the crossbow required no formal training to utilize. Whereas the longbow required elaborate visual, tactile and kinesthetic coordination to achieve any degree of accuracy, the wielder of a crossbow could simply put the weapon to his shoulder, sight along he arrow itself, and be reasonably assured of hitting his target.

Moreover, since just about the only mounted knights likely to visit your average peasant would be government soldiers and tax collectors, the utility of the device was plain: With it, the common rabble could defend themselves not only against one another, but against their governmental masters. It was the medieval equivalent of the armor-piercing bullet, and, consequently, kings and priests (the medieval equivalent of a Bureau of Alcohol, Tobacco and Crossbows) threatened death and excommunication, respectively, for its unlawful possession.

Looking at later developments, we see how technology like the firearm—particularly the repeating rifle and the handgun, later followed by the Gatling gun and more advanced machine guns – radically altered the balance of interpersonal and inter-group power. Not without reason was the Colt .45 called “the equalizer.” A frail dance-hall hostess with one in her possession was now fully able to protect herself against the brawniest roughneck in any saloon. Advertisements for the period also reflect the merchandising of the repeating cartridge rifle by declaring that “a man on horseback, armed with one of these rifles, simply cannot be captured.” And, as long as his captors were relying upon flintlocks
or single-shot rifles, the quote is doubtless a true one.

Updating now to the present, the public-key cipher (with a personal computer to run it) represents an equivalent quantum leap—in a defensive weapon. Not only can such a technique be used to protect sensitive data in one’s own possession, but it can also permit two strangers to exchange information over an insecure communications channel—a wiretapped phone line, for example, or skywriting, for that matter)—without ever having previously met to exchange cipher keys.

With a thousand-dollar computer, you can create a cipher that a multimegabuck CRAY X-MP can’t crack in a year. Within a few years, it should be economically feasible to similarly encrypt voice communications; soon after that, full-color digitized video images. Technology will not only have made wiretapping obsolete, it will have totally demolished government’s control over information transfer.

I’d like to take just a moment to sketch the mathematics which makes this principle possible. This algorithm is called the RSA algorithm, after Rivest, Shamir, and Adleman who jointly created it. Its security derives from the fact that, if a very large number is the product of two very large primes, then it is extremely difficult to obtain the two prime factors from analysis of their product. “Extremely” in the sense that if primes p and q have 100 digits apiece, then their 200-digit product cannot in general be factored in less than 100 years by the most powerful computer now in existence.

The “public” part of the key consists of (1) the product pq of the two large primes p and q, and (2) one factor, call it x, of the product xy where xy = (p1)(q 1) + 1. The “private” part of the key consists of the other factor y.

Each block of the text to be encrypted is first turned into an integer—either by using ASCII, or even a simple A=01, B=02, C=03, ..., Z=26 representation. This integer is then raised to the power x mod(pq) and the resulting integer is then sent as the encrypted message. The receiver decrypts by taking this integer to the (secret) power y mod(pq).

It can be shown that this process will always yield the original number started with.

What makes this a groundbreaking development, and why it is called “public- key” cryptography, is that I can openly publish the product pq and the number x, while keeping secret the number y—so that anyone can send me an encrypted message, namely a x mod(pq), but only I can recover the original message a, by taking what they send, raising it to the power y and taking the result mod(pq). The risky step (meeting to exchange cipher keys) has been eliminated. So people who may not even trust each other enough to want to meet, may still reliably exchange encrypted messages—each party having selected and disseminated his own pq and his x, while maintaining the secrecy of his own y.

Another benefit of this scheme is the notion of a “digital signature,” to enable one to authenticate the source of a given message. Normally, if I want to send you a message, I raise my plaintext a to your x and take the result mod(your pq) and send that.

However, if in my message, I take the plaintext a and raise it to my (secret) power y, take the result mod(my pq), then raise that result to your x mod(your pq) and send this, then even after you have normally “decrypted” the message, it will still look like garbage. However, if you then raise it to my public power x, and take the result mod(my pubic pq), so you will not only recover the original plaintext message, but you will know that no one but I could have sent it to you (since no one else knows my secret y).

And these are the very concerns by the way that are today tormenting the Soviet Union about the whole question of personal computers.

On the one hand, they recognize that American schoolchildren are right now growing up with computers as commonplace as sliderules used to be—more so, in fact, because there are things computers can do which will interest (and instruct) 3- and 4-year-olds. And it is precisely these students who one generation hence will be going head-to-head against their Soviet counterparts. For the Soviets to hold back might be a suicidal as continuing to teach swordsmanship while your adversaries are learning ballistics. On the other hand, whatever else a personal computer may be, it is also an exquisitely efficient copying machine—a floppy disk will hold upwards of 50,000 words of text, and can be copied in a couple of minutes. If this weren’t threatening enough, the computer that performs the copy can also encrypt the data in a fashion that is all but unbreakable. Remember that in Soviet society publicly accessible Xerox machines are unknown. The relatively few copying machines in existence are controlled more intensively than machine guns are in the United States.

Now the “conservative” position is that we should not sell these computers to the Soviets, because they could use them in weapons systems.

The “liberal” position is that we should sell them, in the interests of mutual trade and cooperation—and anyway, if we don’t make the sale, there will certainly be some other nation willing to.

For my part, I’m ready to suggest that the Libertarian position should be to give them to the Soviets for free, and if necessary, make them take them... and if that doesn’t work load up an SR-71 Blackbird and air drop them over Moscow in the middle of the night. Paid for by private subscription, of course, not taxation...

I confess that this is not a position that has gained much support among members of the conventional left-right political spectrum, but, after all, in the words of one of Illuminatus’s characters, we are political non-Euclideans: The shortest distance to a particular goal may not look anything like what most people would consider a “straight line.” Taking a long enough world-view, it is arguable that breaking the Soviet government monopoly on information transfer could better lead to the enfeeblement and, indeed, to the ultimate dissolution of the Soviet empire than would the production of another dozen missiles aimed at Moscow.

But there’s the rub: A “long enough” world view does suggest that the evil, the oppressive, the coercive and the simply stupid will “get what they deserve,” but what’s not immediately clear is how the rest of us can escape being killed, enslaved, or pauperized in the process.

When the liberals and other collectivists began to attack freedom, they possessed a reasonably stable, healthy, functioning economy, and almost unlimited time to proceed to hamstring and dismantle it. A policy of political gradualism was at least conceivable. But now, we have patchwork crazy-quilt economy held together by baling wire and spit.

The state not only taxes us to “feed the poor” while also inducing farmers to slaughter milk cows and drive up food prices—it then simultaneously turns around and subsidizes research into agricultural chemicals designed to increase yields of milk from the cows left alive. Or witness the fact that a decline in the price of oil is considered as potentially frightening as a comparable increase a few years ago.

When the price went up, we were told, the economy risked collapse for for want of energy. The price increase was called the “moral equivalent of war” and the Feds swung into action. For the first time in American history, the speed at which you drive your car to work in the morning became an issue of Federal concern. Now, when the price of oil drops, again we risk problems, this time because American oil companies and Third World basket-case nations who sell oil may not be able to ever pay their debts
to our grossly over-extended banks. The suggested panacea is that government should now re-raise the oil prices that OPEC has lowered, via a new oil tax. Since the government is seeking to raise oil prices to about the same extent as OPEC did, what can we call this except the “moral equivalent of civil war—the government against its own people?”

And, classically, in international trade, can you imagine any entity in the world except a government going to court claiming that a vendor was selling it goods too cheaply and demanding not only that that naughty vendor be compelled by the court to raise its prices, but also that it be punished for the act of lowering them in the first place? So while the statists could afford to take a couple of hundred years to trash our economy and our liberties – we certainly cannot count on having an equivalent period of stability in which to reclaim them. I contend that there exists almost a “black hole” effect in the evolution of nationstates just as in the evolution of stars. Once freedom contracts beyond a certain minimum extent, the state warps the fabric of the political continuum about itself to the degree that subsequent re-emergence of freedom becomes all but impossible. A good illustration of this can be seen in the area of so-called “welfare” payments. When those who sup at the public trough outnumber (and thus outvote) those whose taxes must replenish the trough, then what possible choice has a democracy but to perpetuate and expand the taking from the few for the unearned benefit of the many? Go down to the nearest “welfare” office, find just two people on the dole... and recognize that between them they form a voting bloc that can forever outvote you on the question of who owns your life—and the fruits of your life’s labor.

So essentially those who love liberty need an “edge” of some sort if we’re ultimately going to prevail. We obviously can’t use the altruists’ “other-directedness” of “work, slave, suffer, sacrifice, so that next generation of a billion random strangers can live in a better world.” Recognize that, however immoral such an appeal might be, it is nonetheless an extremely powerful one in today’s culture. If you can convince people to work energetically for a “cause,” caring only enough for their personal welfare so as to remain alive enough and healthy enough to continue working—then you have a truly massive reservoir of energy to draw from. Equally clearly, this is just the sort of appeal which tautologically cannot be utilized for egoistic or libertarian goals. If I were to stand up before you tonight and say something like, “Listen, follow me as I enunciate my noble ‘cause,’ contribute your money to support the ‘cause,’ give up your free time to work for the ‘cause,’ strive selflessly to bring it about, and then (after you and your children are dead) maybe your children’s children will actually live under egoism”—you’d all think I’d gone mad. And of course you’d be right. Because the point I’m trying to make is that libertarianism and/or egoism will be spread if, when, and as, individual libertarians and/or egoists find it profitable and/or enjoyable to do so. And probably only then.

While I certainly do not disparage the concept of political action, I don’t believe that it is the only, nor even necessarily the most cost effective path toward increasing freedom in our time. Consider that, for a fraction of the investment in time, money and effort I might expend in trying to convince the state to abolish wiretapping and all forms of censorship—I can teach every libertarian who’s interested how to use cryptography to abolish them unilaterally.

There is a maxim—a proverb—generally attributed to the Eskimoes, which very likely most Libertarians have already heard. And while you likely would not quarrel with the saying, you might well feel that you’ve heard it often enough already, and that it has nothing further to teach us, and moreover, that maybe you’re even tired of hearing it. I shall therefore repeat it now:

If you give a man a fish, the saying runs, you feed him for a day. But if you teach a man how to fish, you feed him for a lifetime.

Your exposure to the quote was probably in some sort of a “workfare” vs. “welfare” context; namely, that if you genuinely wish to help someone in need, you should teach him how to earn his sustenance, not simply how to beg for it. And of course this is true, if only because the next time he is hungry, there might not be anybody around willing or even able to give him a fish, whereas with the information on how to fish, he is completely self sufficient.

But I submit that this exhausts only the first order content of the quote, and if there were nothing further to glean from it, I would have wasted your time by citing it again. After all, it seems to have almost a crypto-altruist slant, as though to imply that we should structure our activities so as to maximize the benefits to such hungry beggars as we may encounter.

But consider:

Suppose this Eskimo doesn’t know how to fish, but he does know how to hunt walruses. You, on the other hand, have often gone hungry while traveling through walrus country because you had no idea how to catch the damn things, and they ate most of the fish you could catch.

And now suppose the two of you decide to exchange information, bartering fishing knowledge for hunting knowledge. Well, the first thing to observe is that a transaction of this type categorically and unambiguously refutes the Marxist premise that every trade must have a “winner” and a “loser”–the idea that if one person gains, it must necessarily be at the “expense” of another person who loses.

Clearly, under this scenario, such is not the case. Each party has gained something he did not have before, and neither has been diminished in any way.

When it comes to exchange of information (rather than material objects) life is no longer a zero-sum game. This is an extremely powerful notion. The “law of diminishing returns,” the “first and second laws of thermodynamics”—all those “laws” which constrain our possibilities in other contexts—no longer bind us! Now that’s anarchy!

Or consider another possibility:

Suppose this hungry Eskimo never learned to fish because the ruler of his nation-state had decreed fishing illegal. Because fish contain dangerous tiny bones, and sometimes sharp spines, he tells us, the
state has decreed that their consumption—and even their possession—are too hazardous to the people’s health to be permitted . . . even by knowledgeable, willing adults. Perhaps it is because citizens’ bodies
are thought to be government property, and therefore it is the function of the state to punish those who improperly care for government property. Or perhaps it is because the state generously extends to competent adults the “benefits” it provides to children and to the mentally ill: namely, a full-time, all-pervasive supervisory conservatorship—so that they need not trouble themselves with making choices about behavior thought physically risky or morally “naughty.” But, in any case, you stare stupefied, while your Eskimo informant relates how this law is taken so seriously that a friend of his was recently imprisoned for years for the crime of “possession of nine ounces of trout with intent to distribute.”

Now you may conclude that a society so grotesquely oppressive as to enforce a law of this type is simply an affront to the dignity of all human beings. You may go farther and decide to commit some portion of your discretionary, recreational time specifically to the task of thwarting this tyrant’s goal. (Your rationale may be “altruistic” in the sense of wanting to liberate the oppressed, or “egoistic” in the sense of proving you can outsmart the oppressor—or very likely some combination of these or perhaps even other motives.)

But, since you have zero desire to become a martyr to your “cause,” you’re not about to mount a military campaign, or even try to run a boatload of fish through the blockade. However, it is here that technology—and in particular information technology—can multiply your efficacy literally a hundredfold. I say “literally,” because for a fraction of the effort (and virtually none of the risk) attendant to smuggling in a hundred fish, you can quite readily produce a hundred Xerox copies of fishing instructions. If the targeted government, like present-day America, at least permits open discussion of topics whose implementation is restricted, then that should suffice. But, if the government attempts to suppress the flow of information as well, then you will have to take a little more effort and perhaps write your fishing manual on a floppy disk encrypted according to your mythical Eskimo’s public-key parameters.

But as far as increasing real-world access to fish you have made genuine nonzero headway—which may continue to snowball as others redisseminate the information you have provided. And you have not had to waste any of your time trying to convert ideological adversaries, or even trying to win over the undecided. Recall Harry Browne’s dictum from “Freedom in an Unfree World” that the success of any endeavor is in general inversely proportional to the number of people whose persuasion is necessary to its fulfilment.

If you look at history, you cannot deny that it has been dramatically shaped by men with names like Washington, Lincoln, Nixon, Marcos, Duvalier, Khadaffi and their ilk. But it has also been shaped by people with names like Edison, Curie, Marconi, Tesla and Wozniak. And this latter shaping has been at least as pervasive, and not nearly so bloody.

And that’s where I’m trying to take The LiberTech Project. Rather than beseeching the state to please not enslave, plunder or constrain us, I propose a libertarian network spreading the technologies by which we may seize freedom for ourselves.

But here we must be a bit careful. While it is not (at present) illegal to encrypt information when government wants to spy on you, there is no guarantee of what the future may hold. There have been bills introduced, for example, which would have made it a crime to wear body armor when government wants to shoot you. That is, if you were to commit certain crimes while wearing a Kevlar vest, then that fact would constitute a separate federal crime of its own. This law to my knowledge has not passed, yet ... but it does indicate how government thinks.

Other technological applications, however, do indeed pose legal risks.

We recognize, for example, that anyone who helped a pre-Civil War slave escape on the “underground railroad” was making a clearly illegal use of technology—as the sovereign government of the United States of America at that time found the buying and selling of human beings quite as acceptable as the buying and selling of cattle. Similarly, during Prohibition, anyone who used his bathtub to ferment yeast and sugar into the illegal psychoactive drug, alcohol—the controlled substance, wine—was using technology in a way that could get him shot dead by federal agents for his “crime”–unfortunately not to be restored to life when Congress reversed itself and re-permitted use of this drug.

So, to quote a former President, un-indicted co-conspirator and pardoned felon: “Let me make one thing perfectly clear:” The LiberTech Project does not advocate, participate in, or conspire in the violation of any law—no matter how oppressive, unconstitutional or simply stupid such law may be. It does engage in description (for educational and informational purposes only) of technological processes, and some of these processes (like flying a plane or manufacturing a firearm) may well require appropriate licensing to perform legally. Fortunately, no license is needed for the distribution or receipt of information itself.

So, the next time you look at the political scene and despair, thinking, “Well, if 51% of the nation and 51% of this State, and 51% of this city have to turn Libertarian before I’ll be free, then somebody might
as well cut my goddamn throat now, and put me out of my misery”— recognize that such is not the case. There exist ways to make yourself free.

If you wish to explore such techniques via the Project, you are welcome to give me your name and address—or a fake name and mail drop, for that matter—and you’ll go on the mailing list for my erratically published newsletter. Any friends or acquaintances whom you think would be interested are welcome as well. I’m not even asking for stamped self-addressed envelopes, since my printer can handle mailing labels and actual postage costs are down in the noise compared with the other efforts in getting an issue out. If you should have an idea to share, or even a useful product to plug, I’ll be glad to have you write it up for publication. Even if you want to be the proverbial “free rider” and just benefit from what others contribute—you’re still welcome: Everything will be public domain; feel free to copy it or give it away (or sell it, for that matter, ’cause if you can get money for it while I’m taking full-page ads trying to give it away, you’re certainly entitled to your capitalist profit...) Anyway, every application of these principles should make the world just a little freer, and I’m certainly willing to underwrite that, at least for the foreseeable future.

I will leave you with one final thought: If you don’t learn how to beat your plowshares into swords before they outlaw swords, then you sure as HELL ought to learn before they outlaw plowshares too.

High Speed Transport With Elon Musk





This item is of course short on details, but addresses the serious need for high speed connectors between population centers. Can an air based system do the trick?

I do not think so. The air flow has to surpass the speed of sound in order to achieve speeds in excess of the speed of sound and the internal drag pretty well ends that in a tube system.

What I would try though is to put the weight of the entire train on an air pad which needs on board compression. I would also use that on board compression to apply the Coanda effect to lift the bow wave up and over the bow. We would still have a lot of drag on the train itself but otherwise it is still an open air proposition.

Curiously, we should be able to tap bow pressure to take over the compression task and possibly use the escaping air to limit drag along the lower edges.

Such a train may possibly match the speed of an airliner although I suspect we would need to get serious about banking the road bed itself.

A better solution may well be an evacuated tube because that we know is a one time expense. Then the only limit on speed will be the g's on the curves. I would also place the tube above ground as much as possible and this will need a rethink on our material options.

For the present, current high speed technocracy is satisfactory to our needs and can be bought off the shelf. The problem in North America has been historic ownership. This has to be addressed in an innovative way.


Elon Musk Will Propose a Crashproof Pneumatic 1000 mph Hyperloop Transportation System

AUGUST 01, 2012

Musk also cites Aeromovel as a similar transportation network, meaning that the Hyperloop could take advantage of a similar pneumatic transportation guideway.

This system I have in mind, how would you like something that can never crash, is immune to weather, it goes 3 or 4 times faster than the bullet train… it goes an average speed of twice what an aircraft would do. You would go from downtown LA to downtown San Francisco in under 30 minutes. It would cost you much less than an air ticket than any other mode of transport. I think we could actually make it self-powering if you put solar panels on it, you generate more power than you would consume in the system. There's a way to store the power so it would run 24/7 without using batteries. Yes, this is possible, absolutely.

LA Times talks to Elon Musk in an interview. California high speed rail is starting up, but you've proposed an alternative — maybe solar-powered, maybe on a pneumatic track — you call the hyperloop?

I've got to find the time to write up the details. I'm going to put it on a blog and open-source the idea. Why are we, in the center of high tech, doing such a bad job [with high-speed rail]? It's embarrassing. It says all sorts of wrong things about our state. I was thinking about what could be better, state of the art? That's where I came up with the idea for a fifth mode of Earth transport, apart from planes, trains, automobiles and boats. The hyperloop could go from city center to city center in not much more than a half-hour.

Aeromovel blowers propel air (under low pressure) through a duct built into the guideway. The pressurized air pushes a propulsion plate attached to the bottom of the vehicle. This propulsion plate acts like an upside down sail, propelling the vehicle forward and helping to stop it when the air flow is reversed.

Aeromovel

Air propulsion eliminates the problems of heavy rail traction; wear on wheels and tracks is reduced to a minimum.


Acceleration and deceleration are smooth and efficient; traction noise and vibration are minimized; vehicle speed can reach 80 km per hour (50 mph) in urban applications.


The combination of pneumatic propulsion and non-axle wheel design permits AEROMOVEL® vehicles to climb steep gradients up to 12% and traverse sharp curves with a radius as low as 25 meters (82 Feet).

The vehicle is driven by a pneumatic propulsion system which converts electrical power into air flow and transmits thrust directly to the vehicle without gears or intervening electric circuits.


Stationary electrical blowers, located close to the passenger stations produce the necessary pressurized air, which is generated according to the desired vehicle acceleration rate and speed.


Excellent system reliability is achieved by using these sturdy, proven industrial components.


The power propulsion units are completely contained in sound-insulated housing units.


The variable speed motors increase efficiency and minimize any loss of energy.


Large, powerful motors provide AEROMOVEL® with a wide range of air movement capability, while keeping the cost of operation and maintenance at a minimum.


The stationary power propulsion units reduce wear and allow simple and efficient maintenance, because they are separated from the moving vehicle.
