With Compressed Air to RUN YOUR CAR :
# - 1994, Guy NEGRE, France, Compressed Air Car: at http://www.mdi.lu
For those who still believe that there is no alternative to oil to run our cars, this will prove you that you are wrong; the compressed-air cars are running, efficiently, without noise and pollution, at almost zero cost (fuel tank for 1,5 Euro, RM 8), and they are produced in already 35 factories around the world. Solutions exist but the governments and officials block them, please open your eyes.
The ex-Formula 1 Engineer Guy Negre, designed a completely new motor, hybrid that can run on compressed air, but also on oil … Mexico City, one of the most polluted in the world, signed a contract to convert its 7,000 taxis to compressed air taxis.

# The "zero pollution" engine from http://www.zeropollution.com/zeropollution/francais.html
 
In city, using only compressed air, with 5 persons onbard the autonomy is 200 km, using 300 litres of air compressed at 300 bar in glass or carbon fiber tanks.
# From GIZMAG.com : "French auto runs on compressed air technology"
French engineers have designed a low consumption and low pollution engine for urban motoring that runs on compressed air technology. The CATS (Compressed Air Technology System) "air car" from Motor Development International is a significant step for zero-emission transport, delivering a compressed air-driven vehicle that is safe, quiet, has a top speed of 110 km/h and a range of 200 km. Costing next to nothing to run, the Zero Emission Vehicle (ZEV) range - which includes a pick-up truck and van - is set for release in early 2005.
… since 1994. The two-stroke engine is powered by compressed air stored in tanks at about 150 times the pressure of tyres on a car. The expansion of the compressed air drives the pistons to create movement, replacing the burning of fossil fuel in a conventional engine. In an air-refilling station (currently unavailable as service stations have not been fitted yet) it is estimated to take between three and four minutes to re-fuel. At home, with a 220V plug, it takes three and a half hours.
Nègre estimates a full tank of air will cost around 1.50 euros to fill and that the extra reward is knowing that you are pumping nothing harmful into the atmosphere. The hidden environmental cost with the CATS is that electricity must still be generated and the means of that production may still employ fossil fuels that discharge pollutants. Still, the savings to the pocket and environment appear well worth investigating. Four models are available for the commercial market - the MiniCAT car at approximately €6 860 euros, or the CitiCATs, including a taxi (with room for up to 5 passengers), a Pick-Up truck and a van, all retailing for approximately €9,460 euros plus taxes.
Air powered engine
This engine uses an innovative system to control the movement of the 2nd generation pistons and one single crankshaft. The pistons work in two stages: one motor stage and one intermediate stage of compression/expansion. The engine has 4 two-stage pistons, i.e. 8 compression and/or expansion chambers. They have two functions: to compress ambient air and refill the storage tanks; and to make successive expansions (reheating air with ambient thermal energy) thereby approaching isothermic expansion. Its steering-wheel is equipped with a 5kW electric moto-alternator. This motor is simultaneously:1/ the motor to compress air o the starting motor 2/ the alternator for recharging the battery 3/ an electric moderator/brake 4/ a temporary power supply (e.g. for parking).

# - Welcome to Engineair, from http://www.engineair.com.au
Engineair Pty Ltd, based in Melbourne, Australia is a company focusing on the development of air motor technology based on a unique rotary piston concept. Different from conventional air motors, the Engineair motor, invented by Mr Angelo Di Pietro, has virtually eliminated internal wear and friction and offers superior performance at a wide variety of application requirements.
 
Angelo Di Pietro Director of R & D said:
"There is no other motor as good as ours, years of research and analysing other motors around the world gave me the confidence and obligation to say so. Obligation in the sense that people have been waiting for ages in relation to efficiency in order to take care of our environmental situation.
100% more efficiency than our competitor is a very serious claim and should not be confused with some kind of publicity stunt were the interest is purely to try and make money out of some ridiculous claim.
The invention has a long list of important improvements over other motors.
The concept has the capability to change the method we use for transportation, apart from the benefits of energy saving in stationary applications.
- We have verification of its performance
- We have patents issued
- It has outstanding efficiency
- It has constant high torque
- It has low parts count
- It has low number of moving parts
- It is compact and light
- It has virtually no friction
- It has virtually no vibration
- It has smooth speed control characteristics
- Only 1 PSI of pressure is needed to overcame the friction THAT'S CORRECT ONLY 1 PSI !!
