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

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

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

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
