Sure, we have plenty of air, so why not use it to motor around in Tata Nano cars? The company that boasts they can build a $2,500 car is working on an air-powered model with an engine from MDI Enterprises. The engine uses compressed air to make it very cold, then it is heated and fed into the cylinders of a piston engine driving the power. Since nothing combusts, there is no pollution. The Nano with the air powered engine will travel 200 km/h for about $3 worth of electricity. Since environmentalists have worried that the super cheap Tata will overrun India, the company responded with this alternative.
Below are four more air-powered cars.
