Forget batteries, the new hotness is compressed air

The greener car of tomorrow just might be powered with compressed air.

Zero Pollution Motors is a 15-year-old company based in France that is planning on releasing a car next year in the U.S. that runs on compressed air. Their cars use air tanks filled with compressed air to drive the engine. At less than 35 mph the engine uses the air exclusively, at higher speeds a heater warms and speeds up the air, recharging the air tank along the way. At the lower speeds a tank of air would take you 20 miles, traveling at faster speeds (engaging the heater and air compressor) would get you 100+ miles.
 
Air powered cars have disadvantages -- they can take a long time to recharge. Zero Pollution Motors expects a four-hour recharge time for their tanks, and some experts question the true efficiency of the model -- air compressors take a lot of energy to run and appear to be less efficient than hybrid cars in terms of miles/unit of energy.
 
But I think air powered technology comes out on top for one simple reason -- it doesn't require batteries. Batteries are heavy, expensive and made from exotic and limited materials like lithium. Air-powered cars just need an air tank and a compressor. It might not turn out to be the best choice for every transportation need but will find a few niches that it's perfect for. I'd love to have an air-powered riding lawn mower and would enjoy tooling around town in a small car exhausting nothing more than air.

It is my ~“opinion”~ what I have been ~“given”~ has ~“the power”~ to ~“enlighten”~ and ~“awaken”~ the world!

This idea has been fielded a dozen times and has failed that many times too. Compressed air is about the crappiest way to store energy you can imagine. The way this one operates, they make it sound like a perpetual motion machine. A car in india was 1/2 air tank, half car (2 seats, giant air tank) and it has a range of... 18 miles per charge. Wow.

Lighter cars aren't necessarily good either. Maybe for you fools how still live in the city and drive on streets so crowded no one can.... More

Funny name anyway if you consider that emissions from even the dirtiest car are less than the pollution caused by its whole production process. Producing a Toyota Prius, and also breaking it down again after use, is even more polluting because of its battery. This little car here doesn't have a battery I guess, so would be less polluting than that, but for the materials it is made of mines will have to be operated which costs oil and causes pollution, oil will be used directly for the....

Didier, thanks for your reply. And yes, I in fact do want people to stop buying cars and all other goods and see the world economy collapse. Oh yes I do. That we need the economy is not a fact, but a myth. That the economy is good for people is a myth too. It is good for the ultimate top of the pyramid, but it is hell for those below them. There is no way for civilization to become sustainable, as long as you consider the Larger Picture. A small improvement merely makes the destructiveness of.... More

Lets look at this for a second. They forget to mention in this article that you can fill this air car up at a gas station tir air pump for 75 cents and in just a few minutes. Plugging it into an outlet is just a back up way to recharge if you want at home. 75 cents to go a distance of 100 miles at up to 98 mph. And you can fill it up at any gas station.

And you want to tell me I should buy a car that's twice as much and that I can't fill up anywhere, and it takes 45 minutes??? Are.... More

To Arthur Sevestre of the first post: You're right, whatever we buy has to be made and transported. But what is your alternative? Do you want people to stop buying cars and all other goods and see the world economy collapse? Or shouldn't we applaud even small changes to the better? The company developping the air cars is the French MDI and I can assure you that they are very invironmentally minded. They are looking into making the bodywork from hemp, recuperate heat from production process for.... More

Lovely example of the idea that technology can save the world! Can it?

Even if this idea would 'take flight', you need to produce this car. Materials will have to be mined, shipped, assimilated, etc., all costing enormous amounts of energy, oil and causing enormous amounts of pollution and destruction, just like with 'normal' cars. Perhaps slightly less material will be needed and less destructive materials at that, but that would not make this car environmentally friendly; only a.... More

Compressing air may "take a lot of energy to run and appear to be less efficient than hybrid cars," but air compression technology is way simpler than what will be required to replace todays gas vehicles with millions of lithium-ion batteries. (Is there enough lithium on the globe to produce all those cars?). The air-compression are gas engines without the gas, carburetor, spark plugs and about everything complicated. We know how to compress air, we only need to make it more efficient. If we.... More

Took a big course on this. You cannot fit enough air (even compressed) onboard to go long distances.

EVERYone cool wants a Tesla Model S (2011).. Chevy volt, 40 mile electric vs Tesla Model S (150-300). with a 45 Minute recharge. 0-60 in under 6 sec (if you really want speed, their Roadster is probably THE fastest car off the line, and youtube will back this up. Ahmen.
