Well, some power has to be used to compress the air, so where is the savings? I would not like to be in one of those things in a wreck wherein the air tank ruptured. The tech specs are remarkably absent from the articles.
Nothing will do well commercially here unless it provides the public with autos they prefer,air,hybrid or gas.

These minature pieces of sh.it are not going to be sold except to environmental whackos.
You may be on to something there, Paladin -

reading further, it appears they are most efficient when using heated air.

Yep, these cars would definitely appeal to those who already revel in hot air!
I hate those so-called "Futuristic" designs that car manufacturers seem to be using lately. they're so ugly and they certainly don't remind me of anything that even resembles "advanced technology".

Whatever ever happened to using the more classic designs? :p
The looks might catch on,who knows? the size simply is ridiculous and not many of us will buy.

Economics and the desire of the people have to come together. This is just a variation off the smart car,which I find a death trap.
yeah, the size is an issue for me too as well.

now those people have the right idea when it comes to giving an hybird/eco-friendly car style:

now that's class!
Plug in hybrid makes some good sense. However,adding the electric bill increase and battery costs for replacement,I'd like to see a study done to show where gas prices need to be to make them economically feasible.
I actually don't pay much in terms of electric bills here... all part of living in an apartment I guess?

So I wouldn't mind an electric/gas hybrid car. But like you, I do wonder just how much gas I would be saving exactly by using such a car.
Well, you would certainly not use as much gas from the local gas station.

The question is how much gas or other fuel will it take to power the car, and whether what it does take is less than what would be used by a conventional gasoline powered similar sized vehicle.
It's small, but it seems to be for city driving so that might not be an issue. The size could help with parking.
I dont think Bubba will be pulling stumps with it.

A flex fuel hybrid is probably the way to go. Run on electricity or burn whatever is available. Better batteries are needed though.
Fuel cell or hydrogen may be the future.
Or these?

My thoughts exactly.

Looks like some poof type would drive this to Starbucks on the way to a Seattle diversity-fest with the weekend being scheduled for tree hugging and communism.

I love my internal combustion engine, the 5.3 Chevy LS motor. It has some gerbils in it, sounds like it has muscle and pulls like a 400 mule train. And it's a truck - so I do not feel like I am castrating myself.
Air car is an original concept, unfortunately it's not enough efficient to provide a decent mileage to a normal car. Assemblic tiny plastic cars is not the solution to our pollution problems.

IMO we need a gas which expands more than air, like azote used by Nasa spacecrafts. But that will become quickely prohibitively expensive.
What kind of device works by compressing a gas, running it through cooling coils to remove the excess heat caused by compression, then by allowing the gas to expand again?

Answer: A REFRIGERATOR!

A vehicle designed to operate on compressed air would have a problem managing temperatures. A sudden rupture of the compressed air tank would not only produce an explosion, it would also produce instant refrigeration, making popsicles out of driver, passengers, and anyone nearby.
Just an aside... My youngest son is now one of the foremost experts on Hybrid automotive technology in the world. He is now on the other side of the world talking to people who have business questions. He can give them the design engineering answers.
what air? compressed air? needs to be squeezed to at least a billion bar for 1,000 miles.
Air probably is not the most efficient substance to use for compressed-air power. You would probably want to use some other gas that is denser than nitrogen-oxygen, or that has greater resistance to compression. The substance with a vastly greater resistance to compression would be water. But then, the heat of compression would give you steam--so we are back to steam power.
My son worked a few years ago with an hydraulic-adaptive system currently being tested on Fed-ex vehicles. I believe the amortized cost would be about $5K and pay for itself rapidly.

Much of that research is seen in cars that collect the energy from braking and putting it back into acceleration, but these electric systems are more expensive and less efficient than the hydraulic.
Ron, for having worked with air-compressed tools, I can tell you that the dilatation of air is not cooling stuffs around.
The process in a fridge is different than that of compressor for tools and engines.

IMO with such device you can unscrew the bolts holding the weels, not actualy power the car.
