Haven't had a chance to look at this yet, but the energy efficiency of cold air is just horrible. We can't even use it to start a jet engine once, not with reasonable size bottles.
I suppose with a zillion psi or so you could store enough energy to be useful - but that would make one heck of a bomb, or cut through just about anything if it ever developed a leak.
My take on it is that cold air (meaning compressed, but not combusted for power) becomes dangerous before it becomes useful as a power source. Of course, with a low enough horsepower requirement, you can make a lot of things work. But I wonder if an equivalently sized gasoline/diesel engine might not be better overall for pollution and fuel use, once you figure in the need to have some way to compress that air in the first place.

Science has solved problems before that were thought impossible to solve. The car is already in production.
Nothing says success - like success.
