From the Beeb: Compressed air cars

BBC Photo

I've been going to the MDI website now for a year, waiting for a press release on these new combined compressed-air/fuel engines. The car itself has been designed now for several years, with a plain compressed air engine. It was the fuel booster for long distance travel that got my attention. Tata, the Indian motor company, will get the technology, it seems. I wonder if waht even offered to the "Big 3?"

Question: Why can't a compressed-air piston engine be designed to run backwards as a compressor? That would reduced weight.

The Aircar can be filled with air in just three minutes
An engineer has promised that within a year he will start selling a car that runs on compressed air, producing no emissions at all in town.

The OneCAT will be a five-seater with a glass fibre body, weighing just 350kg and could cost just over £2,500.

It will be driven by compressed air stored in carbon-fibre tanks built into the chassis.

The tanks can be filled with air from a compressor in just three minutes - much quicker than a battery car.
