Cheap cars with pneumatic

A French engineer promises to sell a compressed-gas-powered car within a year, without the expense of a cheap price. The OneCat will have five seats with a fiberglass body, weighing only 350 kg and priced at just over £ 2,500 a bit.

It runs on compressed air contained in carbon fiber sinks located in the undercarriage. These tanks can be filled with compressed fuel in just 3 minutes, much faster than a car powered by the battery.

With long journeys, the piston-boosted air can be boosted by a fuel combustion boiler, which warms the air, causing it to expand and increase the pressure in the piston. This combustion chamber will use all types of liquid fuels. Designers said the school bus, the car consumes about 3.7 liters of fuel for 190 km. In the city, running with compressed air, the price will be much cheaper.

" The first customers will be those who care about the environment ," said French inventor Guy Negre.

Negre has been optimistic for more than a decade about the coming of a turning point. Independent observers have more recently been convinced that he is gaining support from the Indian giant Tata Corporation to put the engine on the line.

Tata will be the only big company he will register for sale - and they are limited to India. For the rest of the world, he hopes to persuade hundreds of inventors to set up their own factories, manufacturing vehicles from 80% of the material on site.
