The Airpod - a car powered by compressed air
French auto engineer Guy Negre had developed an emission-free car, called the Airpod, which runs on compressed air alone. The car is made of fibreglass and stores its "fuel" in a thermoplastic tank. Able to reach speeds as high as 30mph, the tank can be recharged either overnight or in 1 minute using a special high-pressure pump also invented by Negre and can travel up to 65 miles on a single refill. He is also developing a hybrid fuel version which he says will be able to achieve 100 mph and travel 900 miles on a single gallon of petrol. Deals have been signed to produce the car in the USA, Latin America, several European countries and - after a £30 million agreement with Tata - in India, but as of yet not in the United Kingdom. Probably because in this country you'd get bricks chucked at you by chavs for driving what looks like a cross between a PC mouse and a sellotape dispenser.
