Patrick Posted May 23, 2007 Report Share Posted May 23, 2007 Sounds shady...and also, NOTHING has appeared anywhere about it. Quote Link to comment Share on other sites More sharing options...
Skinner Posted May 23, 2007 Report Share Posted May 23, 2007 if you have 20 million to burn on a air powered car gas pricies are the least of your concern. Quote Link to comment Share on other sites More sharing options...
Farley Posted May 23, 2007 Report Share Posted May 23, 2007 ive heard of somthing like that before on a 4 wheeler....but never heard of it in a car... COULD be tru... HIGHLY doubtful...and it wouldnt be for sale Quote Link to comment Share on other sites More sharing options...
Guest thekingofcrunk17 Posted May 23, 2007 Report Share Posted May 23, 2007 Are you serious? I've never heard of more bull in my life... (The honda, not the air powered idea) Quote Link to comment Share on other sites More sharing options...
BloodRed Posted May 23, 2007 Report Share Posted May 23, 2007 This has been making it across the car forums. Yeah I think it is major BS and of course the person can not answer any tech questions. Quote Link to comment Share on other sites More sharing options...
Ramsey Posted May 23, 2007 Report Share Posted May 23, 2007 If gas was 4 buck a gallon and you only got 15 mpg, you would need to drive 75,000,000 miles for it to be worth it. Quote Link to comment Share on other sites More sharing options...
Mallard Posted May 23, 2007 Report Share Posted May 23, 2007 Well the concept he speaks of is true. There is a guy in France that builds "air-powered" cars. It's the dumbest idea ever. Instead of the piston being driven by the expanding gasses of combustion, it's pushed down by compressed air. However, you constantly lose pressure when it's running, thus losing power. Also, you have to use a compressor to compress the air and store it in the car. The compressor would run on electricity or gasoline. Quote Link to comment Share on other sites More sharing options...
Vander Posted May 24, 2007 Report Share Posted May 24, 2007 I would hope no one would buy a car from someone on ebay that only has a feedback rating of 3! If you spend that much money, they need to have a much higher rating. Quote Link to comment Share on other sites More sharing options...
thorne Posted May 24, 2007 Report Share Posted May 24, 2007 http://www.msnbc.msn.com/id/6138972 BTW the patent rights if real would make that hting worth allot. Quote Link to comment Share on other sites More sharing options...
Guest Mushijobah Posted May 24, 2007 Report Share Posted May 24, 2007 http://www.digitaljournal.com/article/116641/Car_Runs_on_Compressed_Air Nice documentary on them, sounds cool. Rotary compressed air engine anyone? Quote Link to comment Share on other sites More sharing options...
smokin5s Posted May 25, 2007 Author Report Share Posted May 25, 2007 that documentary is pretty cool. you have to wonder, why can't they put an alternator on it and power a pump off of that... so in essense it will power itself. Quote Link to comment Share on other sites More sharing options...
Guest thekingofcrunk17 Posted May 25, 2007 Report Share Posted May 25, 2007 I'm sure there working on it somehow. Quote Link to comment Share on other sites More sharing options...
desperado Posted May 26, 2007 Report Share Posted May 26, 2007 Yeah, gonna be BS on this one. Is it possible, sure. Problem is it's not fucking practical. A car engine could be turned into an air motor with a different cam and some other minor mods. The real issue is getting enough air storage to get the thing to run long enough to get down your driveway and back up. Look at it with air powered paint ball. Those tanks are 4500 psi. But the air compressed in them is about 20 cubic feet. So even if you had a 4500 lb air supply, then you would need a regulator that would flow enough to drop it down to 600 PSI and still flow enough to fill the cylinders at a reasonable rate. And the size of the tank would need to be as big as a car for it to be useful for more than a few minutes. Then look at what it would take to fill the tanks. If you had a 500 gallon tank that was at 4500 PSI, it would take all night to bring it up to pressure. And compressing air to that sort of pressure requires alot of energy. So we are talking about either a 8 horse gas motor, or a 10 horse electric at bare minimum. Now since we all have single phase electric and not commercial 3 phase, the load as the compressor would get to pressure would be about 75 amps. That would be similar to 4 electric dryers running all night in your house. Your electric bill would be in the thousands of dollars, or you would be listening to the drone of a lawnmower engine all night, and feeding it gas. The energy would need to come from somewhere, it's not like you could hook a tire pump to it and produce the 600 PSI needed for it to run.

nurkvinny Posted May 26, 2007 Report Share Posted May 26, 2007 "Due to security reasons we will not show pictures of the engine compartment or the undercarrage of the vehicle" Uh-huh. If you are listing a 20 million dollar car, perhaps you could spell undercarriage correctly? Quote Link to comment Share on other sites More sharing options...
