اتومبيلی که فقط با هوا (باد) کار می کند.

Tata Motors, once derided as the company with a name that sounds like it ought to be spread on a Fillet-o-Fish, has been making some serious forward movement in the past year or two.
Now, hot on the heels (http://www.rozanehonline.com/#) of its recent acquisition of Land Rover and Jaguar, and news of the impending assault on the European market with the Tata Nano, the Indian company is set to release a car powered entirely by air. But is it all hot air? (You see what I did there.)
Turns out it's very much a legitimate prospect. Sure, it looks bloody ordinary, but let's look beyond the styling for the moment. The MiniCAT (Compressed Air Technology), invented by French madman and ex-F1 engineer Guy Negre and his company Motor Development International (MDI), is a lightweight fibreglass urban car built around a tubular chassis which is glued together rather than welded. More importantly than that, and as you've no doubt gathered, it's powered entirely by compressed air.

Around 6000 of these zero-emissions Air Cars are planned to blow onto Indian streets by August 2009.
Tata's Air Car, which MDI calls a MiniCAT, is expected to cost the equivalent of $8177 in India, and would have a range of about 300km between refuels—an event which, due to the fact you're only paying for the power needed to work the compressor, would cost around $2. Until the market for this car is properly developed though, owners will find included a small compressor which can be connected to any regular power supply, and will refill the tank within 3-4 hours.
If all that weren't enough, the Air Car's lack of a combustion engine means that the need for regular oil changes is a thing of the past, as new oil is only needed every 50,000km. That's one very welcome extra zero on the end.

Here's some nifty bullet points for you.
• The Air Car runs a specially developed piston engine that uses a new thermo dynamic cycle offering exceptional energy efficiency.
• Compressed air is stored in carbon fibre tanks, at 300 bar (4,351 psi).
• The CAT engine operates on four cycles: intake and compression, combustion, expansion, and exhaust.
• Outside air is drawn into the compression chamber and compressed to 20 bar (290 psi). At the highest point of pressure (at ‘top dead centre’), this air reaches 400°C (centigrade), and, at that point, air from the storage tank is injected into the combustion chamber.

• Since the injected air is much colder than the compressed air in the chamber, the injected air is heated instantaneously, causing a sudden expansion, which pushes the piston down (in an expansion stroke)
• The air tanks fitted to the underside of the vehicle can hold 300 litres of compressed air, capable of driving the MiniCAT for up to 200km.
• Using a household electrical source, it takes about 4 hours for the vehicle to refill its own compressed air tanks (a rapid three minute recharge is possible using an external high-pressure air pump.
• The MiniCAT runs an electronically controlled continuously variable transmission (CVT)
