An Air Car You Could See in 2009: ZPM’s 106 MPG Compressed-Air Hybrid
Compressed-Air Powered cars could take you over 800 miles on a single fill-up, at speeds of up to 96 mph. They should refuel in less than 3 minutes, and at speeds over 35 mph emit about half the CO2 of a Toyota Prius. Best part? You could see them in the US at the end of next year.
Car-tech aficionados may already be familiar with Zero Pollution Motor’s (ZPM) compressed-air powered car. For those that haven’t heard of it yet, read on:
“The compressed air vehicle is a new generation of vehicle that finally solves the motorist’s dilemma: how to drive and not pollute at a cost that is affordable!”
What happens when you replace the explosions in your car’s combustion chamber with clean compressed air? Well, as long as you lighten things up by replacing heavier parts with aluminum, you end up with a clean, efficient way to power a vehicle.

The world’s first commercial compressed-air powered vehicle is currently being produced by India’s largest automaker, Tata Motors, who is licensing the technology from European-based company MDI (a company powered by the innovation of ex-Formula One engineer Guy Nègre). They anticipate having about 6000 of these vehicles on city streets in India in 2008.
How does an Air Car Work?

Although potentially revolutionary it really isn’t that complicated. What a compressed-air car does is use the force of super-compressed air to move the engine’s pistons up and down, as opposed to explosions produced from injecting a small amount of fuel.
To get things moving on compressed air, weight reduction is a top priority. MDI’s aluminum-based engine weighs half what a normal engine does, and the frame is also built out of lightweight materials (US version will be aluminum?).
ZPM’s US model will store about 3200 cubic feet of compressed air in carbon fiber tanks at 4500 psi. Carbon fiber tanks are used for safety reasons since they tend to split open (as opposed to explode) when punctured.
Compressed air from the tanks will run directly to the engine under speeds of 35 miles per hour. That means that under 35 mph the car qualifies as a zero emissions vehicle. At higher speeds the engine will burn a small amount of fuel to create more compressed air, sort of like how a plug-in hybrid like the Chevy Volt produces on-the-fly electricity. The hybrid air-car setup should be able use any number of fuels, including gasoline, propane, or ethanol.
1 tank of air + 8 gallons of gas = 848 mile range
The car’s compressed air tank can be refilled in about 3 minutes from a service station. To fill it up at home the car would be plugged in, where an onboard compressor would refill the tank in about 4 hours, at an electrical cost of about $2.
If you aren’t sure whether turning electricity into compressed air is really that clean, here are some numbers: at speeds over 35 mph the air car emits about half the CO2 per mile as a 2007 Toyota Prius (0.141lbs of CO2 per mile, while that the Toyota Prius emits 0.34 lbs of CO2 per mile).
Will we actually see a US-model Air Car in 2009/10?
New York startup ZPM, like Tata motors, has licensed technology from Luxembourg-based MDI. MDI also has plans to release these cars in Europe in 2-, 4-, and 6-cylinder models, starting under $15,000.
Despite lightweight construction that could be of concern for passing US safety tests, it appears that air car technology could be available in the US in late 2009. ZPM told PopularMechanics.com earlier this year that it expects to produce the first US model air car at the end of 2009 or early 2010. (Btw, ZPM’s model is also a candidate for the $10 million Automotive X Prize.)
ZPM wants to produce a 6-seater, 75-hp model with a 1000 mile range at 96 mph, all for just $17,800.
The big question I think we all have is: will this car make it through US safety testing? ZPM’s website says that air car models will meet the same safety specifications of all cars driven in the US. As with most of these new hyper-efficient models we’ve seen (like Aptera’s Typ1 or VW’s 1L Car), ZPM claims the vehicle’s “tubular body provides increased resistance in the event of a crash.” The car will also come with Air Bags and ABS braking.
It’s another case of wait-and see, and we can only hope ZPM follows through.

“Are they considering the amount of pollution produced by a power plant in order to compress the air to start with? I mean it sounds like a nice idea, and maybe it is too good to be true, but air doesn’t compress itself.”
I guess you never heard of hydroelectric or wind-generated power? How about something called solar power? Burning coal isn’t the only way to generate electricity. If you’re going to go green, you might as well go green all the way.
This is the best written article that I have seen so far on these vehicles.
Thanks!
I have a fan website at http://www.citycataircar.com that has some of this information, and I’ll be updating it asap.
Interesting idea, but I’m not sure how efficient it’ll be. But I love the exterior design.
i dont’ like the idea of installing a big air tank with the car..
better way is to
1. use an air motor instead of the reciprocating prime mover
2. install a small air cylinder to serve as air fuel sources\
3, install an aircompressor inside the car which could fill up the small cylinder as it travels and which also serves to maintain the required pressure constant in the air fuel tank
This air powered car was invented back in the 1970’s ( and one before that too ). Like the water powered car and cars that get 300 mpg on gasoline, they were all swallowed whole by the big oil companies / banks that control the worlds economy and governments. These people do not want anything to replace their cash cow. Forget the environment - there’s money to be made.
Thank god that the internet is out of their reach.
If you don’t beleive me then google stanly meyer or any other free energy website.
It’s about time people opened their eyes and saw who really controls what we spend our money on.
Tell me how you can “refuel” the air tank to 4500 psi at a service station. In three minutes?!? Has anybody ever tried to put that kind of pressure in anything? You’d have to have one honking mother of an air compressor! And a leak with that kind of pressure behind it will cut your head off if you get too close. Let’s get real, folks.
This Newsweek interview offers the key to the US: Minivan size. 200 miles or so. Stop. Recharge over lunch (not over night) Go another 200 miles.
Tough to convince two worker families three cars - buy two Prius-types (for regular commutes) and one minivan (for shopping and vacation).

Most people travel less than 50 miles a day.
And 99 percent of travel is under 200 miles [a day]. There is the occasional road trip, but that’s actually pretty rare, and for some people it’s never. Our second model will address that rare case in two ways. One is to allow people to switch out the battery pack, so you can go to a battery-change station just like you’d go to a gas station. The second path is to have a high-speed charge. If you have a high-powered onboard charger, you can get an 80 percent charge in 45 minutes. If you’re going from L.A. to San Francisco, which is about a 400-mile trip, you can drive 200 miles, stop for lunch, charge your car in the restaurant parking lot, finish lunch and continue the remaining 200 miles to San Francisco.

$15000? They’re selling for $2500 in India.
this is called revenge on the oil mafia f them.
