Volution car that is being built by Zero Pollution Motors , in Brignoles, France. The cars have generated a lot of interest in recent years, and the Mexican government has already signed a deal to buy 40,000 e. Makers of the e. Volution are marketing the vehicle as a low pollution or zero pollution car. However, there is still some debate as to what the environmental impact of these air-powered cars will be.
Manufacturers suggest that because the cars run on air they are environmentally friendly.
Critics of the air-powered car idea say that the cars only move the air pollution from the car's exhaust to somewhere else, like an electrical power plant. These cars do require electricity in order for the air to be compressed inside the tanks, and fossil fuel power is needed to supply electricity. This air is fed through an air injector to the engine and flows into a small chamber, which expands the air. The air pushing down on the pistons moves the crankshaft, which gives the vehicle power.
