Car to run on air

Indian car company Tata is backing an air powered car called the OneCAT. This five-seater holds compressed air in carbon-fiber tanks that can be filled in just three minutes.

According to the BBC, “For long journeys the compressed air driving the pistons can be boosted by a fuel burner which heats the air so it expands and increases the pressure on the pistons. The burner will use all kinds of liquid fuel.” The OneCAT will use about 120 mpg on longer trips.

The builders assure us not to worry about the air tanks exploding during an accident. “There’s no issue with safety–if the air-car crashes the air tanks won’t shatter–they will split with a very loud bang. ‘The biggest risk is to the ears.'”
