Air Car - First Air-Powered Car - Zero Emissions - Behind the Tech - Popular Mechanics

Air Car - First Air-Powered Car - Zero Emissions - Behind the Tech - Popular Mechanics: "India’s largest automaker is set to start producing the world’s first commercial air-powered vehicle. The Air Car, developed by ex-Formula One engineer Guy N�gre for Luxembourg-based MDI, uses compressed air, as opposed to the gas-and-oxygen explosions of internal-combustion models, to push its engine’s pistons. Some 6000 zero-emissions Air Cars are scheduled to hit Indian streets in August of 2008. "

Plasma Gasification Transforms Garbage into Clean Energy | Inventor Spot: "A sealed, stainless steel vessel is filled with a stable gas, such as pure nitrogen. When a 650-volt current passes between two electrodes, electrons are ripped from the air, converting the gas into plasma. As current continues to flow, it creates an intense energy field with plasma arcs, which are like lightning. The radiant energy of the 30,000˚F plasma arcs disintegrates trash into its basic elements by tearing apart the materials' molecular bonds. Tile, wood, nails, glass, metal, plastic, diapers-almost any material can be broken down with Startech's technology, eliminating the time-consuming, tedious and costly process of sorting waste by hand. (Nuclear waste is an exception due to its indestructible isotopes.)"

PopSci's Future of the Car - Concept Cars - Tesla: "Straubel has proven that he can build an electric car that's as good as gas—one that doesn't sacrifice power, range or speed. But does that mean the Tesla Roadster heralds a new era of electric vehicles on every street corner, as he believes? Or will the Tesla, impressive as it is, be remembered as just another electric-vehicle science-fair project?"

Can Think's electric car revolutionize the auto industry? - August 1, 2007

Can Think's electric car revolutionize the auto industry? - August 1, 2007: "Did someone kill the electric car? You wouldn't know it on this bright May morning in Scandinavia, where the idea of a mass-produced battery-powered vehicle is being resurrected and actual cars are scheduled to begin rolling off the production line by year's end."

Electric Racers Speed Past Fuel Dragsters | LiveScience

Electric Racers Speed Past Fuel Dragsters | LiveScience: "PORTLAND, Ore. (AP) -- Straddling a 619-pound motorcycle, Scotty Pollacheck tucks in his knees and lowers his head as he waits for the green light. When he revs the engine, there's no roar. The bike moves so fast that within seconds all that's visible is a faint red taillight melting in the distance.

Pollacheck crosses the quarter-mile marker doing 156 mph; he's traveled 1,320 feet in 8.22 seconds, faster than any of the gas-powered cars, trucks or motorcycles that have raced in the drag sprints on this weekend at Portland International Raceway.

It's particularly impressive given Pollacheck is riding a vehicle that uses no gasoline and is powered entirely by lithium-ion batteries.

Electric vehicles are making their presence felt at amateur drag races across the country, challenging gas-powered cars and motorcycles. The 'amp heads,'' computer geeks and tree-hugging environmentalists driving the electron-powered vehicles are starting to kick some major rear end."
