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."

Ethanol-blend auto emissions no greener than gasoline: study
Ethanol-blend auto emissions no greener than gasoline: study: "'Looking at tailpipe emissions, from a greenhouse gas perspective, there really isn't much difference between ethanol and gasoline,' said Greg Rideout, head of Environment Canada's toxic emissions research.
'Our results seemed to indicate that with today's vehicles, there's not a lot of difference at the tailpipe with greenhouse gas emissions.'"
