Green Cars: 2011 Geneva Auto Show

GENEVA -- The air at the 2011 Geneva Motor Show was ... ahem ... electric (with concept cars, that is). From the bottom of the spectrum with the new Toyota Yaris hybrid, all the way to the top with the purely electric Rolls-Royce Phantom-based 102EX, not since the 1881 Exhibition of Electricity in Paris, which congregated electric technologists from all over the world, has so much wattage been on display.
