please explaine how did you
please explaine how did you make car on air,thank you
What is often missed here is
What is often missed here is the difference between isentropic compression/expansion and isothermal compression/expansion. Isentropic couldn't work for this. It is easy to build, but you waste energy heating the air when compressing, and waste it again cooling it when expanding.
No on has come up with a perfect isothermal design. They best I've heard of is 95% isothermal, and totally impractical for anything portable. MDI's is maybe 70-80% isothermal, which may be close enough to be practical. But it is storage, not energy production. Getting rid of those expensive batteries may make MDI a rule-breaker company.

i want to do a paper presentation on the topic hybrid cars
can i get help from u on this matter
We're still waiting for this
We're still waiting for this car that was discussed in this 3 year old article. We're still waiting for the car that Zero Pollution Motors and MDI announced in 2000 and claimed production would start in 2001.
I bet that we will still be waiting in 2015, since 300 liters of compressed air at 300 bar (3200 cubic feet of air at 4500 psi) only has the same energy as 1.5 liters (0.4 gallons) of gasoline.
The ranges that MDI/ZPM claim for their cars have never been shown to be achievable.
MDI has never let any 3rd party test any of their prototypes, and they have never sold a single car after years and years of promising "production next week".
They will still gladly sell you a license and franchise or accept your investment dollars.

I`M DOING A PROJECT ON AN AIR POWERED TOY CAR "PNEUMATIC".THE SOURCE OF AIR IS TO BE A PRESSURISED 2L PLASTIC BOTTLE AT 3,5 Bar, IT IS TO MOVE A DISTANCE OF 6m & START UNAIDED..HOW CAN I UTILISE ALL THE AIR FROM THE BOTTLE & MAKE IT COVER THE DISTANCE? IM DOING FIRST YEAAR AERONAUTICAL ENGINEERING IN SOUTH AFRICA
