OneCAT was developed by Guy Negre - French engineer from Air Car Factories. The main idea is that the car doesn't produce any pollution, as it works on ...compressed air. Tata is still the only company which bougth the license on this techology and acts as a partner for Negre.
The system is following: the air gets into a small cylinder, compresses to 20 bars by a piston, heats and then heads to a spheric camera. There a cold air is added to heated air and the mixture extends, increasing the pressure. Big cylinder's piston returns back and turns the cranked shaft. So, nothing to burn, nothing to pollute.
To fuel the car, you should fill two air tanks of 300 liters in common, which takes 3 minutes only with a powerful compressor. If you don't have one, connect the car with ordinary rosette, and the in-car compressor will complete the filling in 4 hours. Tata OneCAT covers 200kms on 300 liters and reaches 113 km/h. The [so-called] exhaust is filtered by carbon filters. Thus, the car doesn't pollute the ait at all. Moreover, it cleans the other cars' exhausts by taking it though itself.
And, finally, the price - 5000$. If this is the price for the future ecology, Lexus, BMW, General Motors and others are already dead
