Bionic legs put wheelchairs on notice

OK, so the wheelchair won’t be obsolete until the REX system and its inevitable competitors are a great deal cheaper than US$150k, but I feel safe in assuming that won’t take too long in the grand scheme of things. Even so, as a proof of concept for technology that will allow people with paralysis of the legs to walk – actually walk, not just get around some other way – this is some sweet hardware; as a commenter at MetaFilter put it: “Jokes aside, even though the functionality is fairly constrained, the smile on his face says it’s worth it.” I’m inclined to agree.

Attention economics, redux: why supermodels are like toxic assets

Remember me linking to that article that compared the inflationary bubble in the cult of celebrity to the sub-prime mortgage crisis? Well, here’s a similar (and slightly more serious) piece that explains how supermodels are similar to toxic assets [via MetaFilter]:

Coco [Rocha] is what economists would call a winner in a “winner-take all market,” prevalent in culture industries like art and music, where a handful of people reap very lucrative and visible rewards while the bulk of contestants barely scrape by meager livings before they fade into more stable and far less glamorous careers. The presence of such spectacular winners like Coco Rocha raises a great sociological question: how, among the thousands of wannabe models worldwide, is any one 14 year-old able to rise from the pack? What makes Coco Rocha more valuable than the thousands of similar contestants? How, in other words, do winners happen?

The secrets to Coco’s success, and the dozens of girls that have come before and will surely come after her, have much less to do with Coco the person (or the body) than with the social context of an unstable market. There is very little intrinsic value in Coco’s physique that would set her apart from any number of other similarly-built teens—when dealing with symbolic goods like “beauty” and “fashionability,” we would be hard pressed to identify objective measures of worth inherent in the good itself. Rather, social processes are at work in the fashion modeling market to bequeath cultural value onto Coco. The social world of fashion markets reveals how market actors think collectively to make decisions in the face of uncertainty. And this social side of markets, it turns out, is key to understanding how investors could trade securities backed with “toxic” subprime mortgage assets leading us into the 2009 financial crisis.

Well worth a read; it’s interesting to see someone looking at a market in terms of its social construction rather than as a bunch of mathematical abstractions and assumptions. One of the things that has frustrated my research into economics is the way it always seems to be portrayed as a coldly rational science, without any attempt to understand or deconstruct the emergent social consensus that drives it. This is almost ertainly due to me looking in the wrong places, so if anyone has any suggestions for good sources of social and/or behavioural economic literature that won’t baffle an inquisitive layman, please pipe up in the comments.

There’s platinum in them there spacerocks

Still wondering what the business model might be for commercial space operations, beyond sight-seeing tourist flights, inflatable hotels and space-truckin’ logistics missions on behalf of beleagured nation-state space programs? Well, where there’s rare resources, there’s money to be made… and asteroids are eminently reachable with current technologies, as well as full of rare element goodies that we have little of here on Earth.

Last one to write a FiftyFortyniners-in-space novella is a rotten egg! (Note for Ben Bova and others: previously published works are not eligible.)

Tokyo billboards can guess your age, gender

The technological evolution of billboards continues apace. Three years ago we mentioned billboards that can track the attention paid to them; then there were the billboards that could beam directed soundwaves right into your ears (and your ears alone); then there was the suggestion of billboards that you could hit with a high-5 from your Body Area Network in order to receive more relevant ads. The next step? Hi-tech billboards are on trial in Tokyo, and they’re supposed to be able to assess your age demographic and gender.

This is another one of the arms races of evolutionary psychology, I suspect; the smarter advertising becomes, the more resistant to its more basic forms we’ll get. Or maybe that’s wishful thinking… after all, the only reason there’s money in spam emails is because people are stupid enough to click on the damned things.

Recycling the Pacific Trash Vortex into an island

I don’t know whether or not Kay Kenyon heard about this before writing her Shine anthology story “Castoff World”, but if not, the similarities are uncanny. A Dutch firm of architects have proposed a project to turn the Pacific Trash Vortex into a habitable (and indeed arable) sea-worthy island, simply by recycling in situ all the plasticky crap that’s already there [via SlashDot]:

The Pacific Ocean trash dump is twice the size of Texas, or the size of Spain combined with France.  The Pacific Vortex as it is sometimes called, is made up of four million tons of Plastic.  Cleaning it up is going to cost a lot of money and require a great deal of either scooping up the plastic and shipping it back to shore, or some sort of onsite recycling for building something like Recycled Island.

One of the three major aims of the project is to clean up the floating trash by recycling it on site.  Two, the project would create new land for sustainable habitation complete with its own food sources and energy sources.  Lastly, Recycled Island is to be a sea worthy island.

[…]

Further aspects of the island would be: the creation of “fertile ground” from compost toilets.  The island would also be non-polluting, using natural resources.  Recycled Island would be 10,000 Km2 or the size of Hawaii’s main island.  It would be self-sustaining and not dependant on other countries.  The urban housing would be designed for future climate refugees. These are very lofty goals but if carried out, Recycled Island would turn the trash into a money making enterprise rather than an economic sink hole.

Hmmm… an ideal candidate for city-state status, then. But any nation-state along the edge of the Pacific is going to be a bit uneasy about a recycled island that can move itself around at will, and which isn’t dependent on anyone for anything. Compare and contrast to The Raft from Snow Crash: with the latter, refugees want to invade, assimilate themselves; on the other hand, a self-sufficient pirate island will attract away your own malcontents, weaken your authority.

Recycled Island is a great idea from a technological perspective, but the geopolitics are too horrifying to contemplate. Think of the way Antarctica is being scrabbled over, thanks to its oil reserves; the very same economic pressures and scarcities will eventually make a huge lump of plastic floating in the sea look like a natural resource well worth exploiting. But then, that might mean invading a moving country populated entirely by people displaced by climate change… so I wouldn’t plan for your invasion being a cakewalk if they’ve decided they want to stay.
