Many respected engineers have been trying for years to bring a compressed air car to market, believing strongly that compressed air can power a viable zero pollution" car. Now the first commercial compressed air car is on the verge of production and beginning to attract a lot of attention, and with a recently signed partnership with Tata, India's largest automotive manufacturer, the prospects of very cost-effective mass production are now a distinct possibility. The MiniC.A.T is a simple, light urban car. How does it work? 90m3 of compressed air is stored in fibre tanks. The expansion of this air pushes the pistons and creates movement. It is incredibly cost-efficient to run - according to the designers, it costs less than one Euro per 100Km (about a tenth that of a petrol car). Its mileage is about double that of the most advanced electric car (200 to 300 km or 10 hours of driving), a factor which makes a perfect choice in cities where the 80% of motorists drive at less than 60Km. The car has a top speed of 68 mph. Refilling the car will ... take place at adapted petrol stations to administer compressed air. In two or three minutes, and at a cost of approximately [US$2] the car will be ready to go another 200-300 kilometres. As a viable alternative, the car carries a small compressor which can ... refill the tank in 3-4 hours. At the moment, four models have been made: a car, a taxi (5 passengers), a Pick-Up truck and a van. The final selling price will be approximately [US$11,000]. "Moteur Development International" (MDI) ... has researched and developed the Air Car over 10 years.
