Air Car

Is compressed air the future - or just an accident waiting to happen?

Sounds like a good idea, especially in a city - I also read recently about steam powered cars being developed which are supposed to be clean and fast and have phenomenal torque so they don't needa gearbox

Hmm... all these pollution free vehicles are a load of cobbler IMHO.

Granted, zero tailpipe emissions, but what doe sit take to make compresed air...? How much electricity is used? How was that electricity produced? yadda yadda yadda..

i agree the theory is good but somthing has got to compress the air! You need a supercharger effect to compress air to pwer the motor thus it would never need to stop or fill up it could just keep going. Would need a compressed air supply yo start thou...hmm think i need a copyright

Sorry Philh the only perpetual motion machine ever to work resides in the back of my local Curry House.

You'd only need a decent valve on a pump or something, and I think I'd rather have compressed air in my car than 50 litres of explosive petrol!

No doubt many here will call it part of the labour/green/conspiracy/propaganda though

Well well well...at last the perpetual motion debate rears it ugly head.

My Dad would start harping on about the laws of thermodynamics and all that..well he would, he a physPHD, he's old and he's teacher, so more than qualified to comment. I'm not.

What I do know Phil, is the last vehicle to use the "ram jet" effect, came from Germany, fell out of the sky, and blew the living s**t out of most of southern England. Not a happy perantage.

Lastly, if the're gonna sell these things with an in/un-credible drivetrain, maybe they should consider not alienating any customers that might be persuaded with such hideous styling.

The need a young, nubile, talented autmotive designer (possibly who can't spell half the time) to pen somthing lythe and powerful and sexy, much like himself...any thoughts?

Mouse.

p.s. I can't help thinking that blue one on the home page looks like the unfortunate result of a beer fuelled fling between a matiz and a 996

It sounds like a good idea, it says it only tacks 3 min to refill.

just like a big one of these www.samsmodels.demon.co.uk/aerogc02.html

My main concern with devices like this is what might happen in the event that an accident should puncture the air tank. 300 bar is one hell of a lot of pressure, and while wound carbon fibre will probably crack rather than disintegrate explosively I can still see you ending up sitting on top of an uncontrollable missile.

Looks damn ugly as well

Have a look at the first Q&A

www.theaircar.com/faq.html

It does look awful, put the engine in an old mini and it could be quite interesting.
The air tank might have to go on the roof though!

Hmmm. A 720kg vehicle weighs rather less than a bus though.

It can be used as refrigerator !

The air, while expanding from 300 bar inside the cylinder drops in temperature. After few miles everything locks up totally freezed. And there's no car where you can resolve this problem without external supply of the energy for heating.

Yadda, yadda, thermodynamics.

Why ?, cos' I tried this s***e !

UPDATE:

After a careful re-reading of "How it works" I made a conclusion: 300 bar compressed air, 20 bar piston compression, 280 bar difference. You should have compressed air without traces of water vapour, which is anti-economic and impossible, to prevent nozzle lock. Remains S***e !

Nah, petrol smells better !

Mmmm...Thrust, you don't watch your DVD's carfully enough do you?!?

That's what said!, look one up from your first post divvy!

Let me remind you gently....
..."Sir...err, Sir, are you alright sir?...Good!
...because you just went through a wall..."

I wonder what amount of energy is needed to compress the air to 300bar
