Submission + - Wal-Mart's $200 Linux PC Sells Out (ecogeek.org)

hankmt writes: "About a week ago Wal-Mart began selling a $200 linux machine running on a 1.5 ghz Via C7 processor and 512 megs of RAM. While the specs are useless for vista, it works blazingly fast on Ubuntu with the Enlightenment Window Manager. The machine is now officially sold out of their online warehouses, and the product sales page at WalMart.com is full of glowing reviews from new and old linux users alike."

Submission + - America's First Cellulosic Ethanol Plant (ecogeek.org)

hankmt writes: ""The state of Georgia just granted Range Fuels a permit to create the first cellulosic ethanol plant in America. HECK YES! This is very exciting...why?"

In short: First: Because cellulosic ethanol produces ethanol from cellulose, which all plants have, instead of sugar, which is only abundant in food crops. Second: Because while corn ethanol only produces 1.3 units of energy for everyone unit of energy that goes into growing the crop and converting the sugar to ethanol, cellulosic ethanol can produce as much as 16 units of energy for every one unit of energy put into the process.

The new plant will be online, producing 100 million gallons in 2008."

It's funny.  Laugh.

Submission + - Whirling Twirling Propeller Trike (popularmechanics.com)

hankmt writes: "A student at MIT has built a tricycle that applies force to a giant rear fan, instead of directly to the wheels. The effect...well, it's best to look for yourself, but it would be pretty useful on the post-apocalyptic roads of the Australian Outback. The blades of the trike even have built in LED lights which display colored patterns...and also warn pedestrians of their impending deaths."

Feed Solar-powered Swiss boat crosses the Atlantic (engadget.com)

Filed under: Transportation

MW-Line, a Swiss boat-maker known mostly for its water taxis, has successfully piloted a craft across the Atlantic using nothing but solar power, chocolates, neutrality, and hope. The boat, conspicuously named Sun21, is the first of its eco-friendly kind to attempt the journey. The 46-foot catamaran made the trip -- from the Canary Islands to the Bahamas -- in just under a month, and according to MW-Line, the operating costs are 20 to 45 times lower than traditional motorboats. The company claims their next project is to take a solar-powered ship around the world, and then get righteously wasted.

New Fuel Cell Twice As Efficient As Generators 246

Hank Green writes "A new kind of Solid Oxide Fuel Cell has been developed that can consume any kind of fuel, from hydrogen to bio-diesel; it is over two times more efficient than traditional generators. Acumentrics is attempting to market the technology to off-grid applications (like National Parks) and also for home use as personal Combined Heat and Power plants that are extremely efficient (half as carbon-intensive as grid power.)"

Feed Indian air-powered City Cat car prepares for production run (engadget.com)

Filed under: Transportation

The first commercial car to be powered by compressed air could be about to hit the production lines, as Indian automaker Tata Motors prepares to build ex-Formula One engineer Guy Nègre's design. We're not certain if it's the same air car that we hit just under three years ago, but if it is, it's about time! The City Cat runs on nothing but compressed air -- which can be refueled at "air stations," and overnight using a built-in compressor -- with a not too shabby top speed of 68MPH and a range of 125 miles. The Air Car designers are working on a hybrid version that can compress air while it's operating, potentially making cross-India journeys possible: Toyota Prius, eat your hybrid heart out. As EcoGeek points out, the game ain't up just yet for completely emissions free travel since the problem of the source of the electricity (usually acquired from fossil fuels) has yet to be solved. Plus, the fugly design really doesn't do it any favours: why does "green" have to mean "gah?"
