BBC reports that India could soon see a car that runs on compressed air and runs an impressive 120 miles per gallon. The car is called OneCAT, the inventor is frenchman Guy Negre and the development deal is being backed by Tata, makers of the recent and highly newsworthy Nano.
The car will be driven by compressed air stored in carbon-fibre tanks.
The tanks, built into the chassis, can be filled with air from a compressor in just three minutes - much quicker than a battery car.
Alternatively, it can be plugged into the mains for four hours and an on-board compressor will do the job.
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.
If the car becomes reality, Tata will have exclusive distribution rights.
