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)

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.

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."

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) that is over two times more efficient than traditional generators. Acumentrics is attempting to market the technology both to off-grid applications (like National Parks) and also for home use as personal Combined Heat and Power plants that are extremely efficient (up to two times less carbon-intensive than grid power.)"
