This is old news.

Also you need to compress air some where,   In the process of compressing air there is almost a 50% energy loss in the form of heat release cause by compressing the gases.

As it expands to propel the car the gas get's cooler and reduces the pressure giving you lower efficiency per mole of air then was was put in to compressing that air.

if you buy this, i know of a good deal on a bridge in Arizona ... 



 

What is this?
  Will it be the next big thing? 

  
Tata Motors of India thinks so. 
  What will the Oil Companies do to  stop it?

It is an auto engine that runs on air.  That's right;  air not gas or diesel or electric but just the air around us.  Take a  look.




Tata Motors of India has scheduled the Air Car to hit  Indian streets by August 2012


 
The Air Car, developed by ex-Formula One engineer  Guy N. For Luxembourg-based MDI, uses compressed air to push its engine's  pistons and make the car go.
 
The Air Car, called the  "Mini CAT" could cost around 365,757 rupees in India or $8,177  US.

The Mini CAT which is a simple, light urban car, with a tubular  chassis, a body of fiberglass that is glued not welded and  powered by compressed air.  A Microprocessor is used to control all  electrical functions of the car.  One tiny radio transmitter sends  instructions to the lights, turn signals and every other electrical device  on the car.  Which are not many.

The temperature of the clean  air expelled by the exhaust pipe is between 0-15 degrees below zero, which  makes it suitable for use by the internal air conditioning system with no  need for gases or loss of power.

There are no keys, just an access  card which can be read by the car from your pocket.  According to the  designers, it costs less than 50 rupees per 100 KM, that's about a tenth  the cost of a car running on gas.  It's mileage is about double that  of the most advanced electric car, a factor which makes it a perfect  choice for city motorists.  The car has a top speed of 105 KM per  hour or 60 mph and would have a range of around 300 km or 185 miles  between refuels.  Refilling the car will take place at adapted gas  stations with special air compressors.  A fill up will only take two  to three minutes and costs approximately 100 rupees and the car will be  ready to go another 300 kilometers.

This car can also be filled at  home with it's on board compressor.  It will take 3-4 hours to refill  the tank, but it can be done while you sleep. 

Because there  is no combustion engine, changing the 1 liter of vegetable oil is  only necessary every 50,000 KM or 30,000 miles.  Due to its  simplicity, there is very little maintenance to be done on this  car.

This Air Car almost sounds too good to be true.  We'll  see in August. 2012
