Clean energy claim: Aluminum in car tanks - Green Machines - MSNBC.com
Clean energy claim: Aluminum in car tanks - Green Machines - MSNBC.com: "Woodall says the method makes it unnecessary to store or transport hydrogen — two major challenges in creating a hydrogen economy.
"The hydrogen is generated on demand, so you only produce as much as you need when you need it," he said in a statement released by Purdue this week.
So instead of having to fill up at a station, hydrogen would be made inside vehicles in tanks about the same size as today's gasoline tanks. An internal reaction in those tanks would create hydrogen from water and 350 pounds worth of special pellets."

Gasoline-Free Cars Test Drive Successfully - 13WHAM.com
Gasoline-Free Cars Test Drive Successfully - 13WHAM.com: "(Tarrytown, N.Y./Honeoye Falls, N.Y.) -- A trip that began at the General Motors plant in Honeoye Falls Tuesday morning could bring drivers a step closer to gasoline-free cars.
The two 'Sequel' cars traveled more than 300 miles to Tarrytown, Westchester County, on a single tank of fuel. Instead of gasoline, the fuel cells run on energy produced from a mix of hydrogen and oxygen; the only byproduct is water vapor. "

2007 – Year of the electric car | COSMOS magazine
2007 – Year of the electric car | COSMOS magazine: "The company claims that their battery shows a cycle life in excess of 20,000 charges and discharges while still retaining 85 per cent of its capacity to store energy. If proven, this would be a revolutionary breakthrough, especially since Altairnano also claims their battery can be recharged not in hours, but in less than 10 minutes.
By way of comparison, the typical lithium battery takes from two to six hours to recharge, its power density is less than 1,000 watts per kilogram (w/kg), and it operates over a temperature range of 0�C to 40�C. In contrast, Altairnano's data show that their battery has a power density of 4,000 w/kg and the ability to safely operate from -50� C to 75� C. But just how safe is 'safe'?
To answer this question, Gotcher gave me a description of the various tests to which the company subjected the battery: short circuit, forced discharge, over charge, over discharge, nail puncture, crush, over temperature, and a drop test. The battery survived all these trials without any smoke or fire."

Business 2.0: A car that could save the planet—fast - May. 5, 2006: "SAN FRANCISCO (Business 2.0 Magazine) - Ian Wright has a car that blows away a Ferrari 360 Spider and a Porsche Carrera GT in drag races, and whose 0-to-60 acceleration time ranks it among the fastest production autos in the world. In fact, it's second only to the French-made Bugatti Veyron, a 1,000-horsepower, 16-cylinder beast that hits 60 mph half a second faster and goes for $1.25 million."
