I want one of these: 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.
No word though on how to pronounce the name.
