"…India's largest automaker Tata Motors is set to start producing the world's first commercial air-powered vehicle.The Air Car, developed by ex-Formula One engineer Guy Nègre for Luxembourg-based MDI, uses compressed air, as opposed to the gas-and-oxygen explosions of internal-combustion models, to push its engine's pistons. Some 6000 zero-emissions Air Cars are scheduled to hit Indian streets by August
The Air Car, called the MiniCAT could cost around Rs. 3,50,000 ($ 8177) in India and would have a range of around 300 km between refuels.
The cost of a refill would be about Rs. 85 ($ 2)."
