Eco-Car More Efficient Than Light Bulb

An eco-car that can travel the world using a fraction of the electricity it takes to power a light bulb has been unveiled by its British creators. The hydrogen-powered Ech2o needs just 25 Watts — the equivalent of less than two gallons of petrol — to complete the 25,000-mile global trip, while emitting nothing more hazardous than water, the UK's Press Association reported. But with a top speed of 30mph, the journey would take more than a month to complete, even if the car was driven flat out with no pit-stops. :: CNN Story
