compressed air powered car
Looks like they have a car that runs on compressed air now. All you have to fill is the air tank that takes a couple of hours and then they claim that you can run 1000miles on it. For city use it might be a good deal, but I would be concered about what happens in a accident with that much pressure in the tank:

It takes energy to compress air, and most forms of energy production produce pollution in one form or another. But, France, with their extensive network of nuclear power plants is a much better market for an electrically-powered vehicle (assuming the compressor has an electric motor).

I don't see how they could compress enough air to travel 1000 miles. A typical scuba tank @ 3000 lbs is only 80 cubic ft. Air tools are rated in CFM- cubic feet per minute. A moderate size air tool might use 4 CFM, meaning a scuba tank would only run it for 20 minutes. I notice that Lowes has an air tool system that uses small disposable (and expensive) air tanks. They don't look big enough to run a tool for more than a couple minutes. Good point about crashes- a scuba tank exploded here in FL while being filled, and took most of the dive shop with it when it blew.

Using a gas would probably make more power and cfpm There is a
limit(dot) on the pressure of even carrying scuba tanks and that is 230bar so that would limit on the distance. That quasiturbine motor can be powered by compressed
air. There is a pump thing for scuba that is basically a pressure amplifier and it allows
you to take say 4 tanks that are low on air and take them and use that air in them to
refill another tank that way the 4 tanks are completely empty and the 5th is full, I
forget what it is called but i wonder if something like that could be used to increase
the pressure and power the motor since it is powered by the air itself it could work
it would seem. I can't for the life of me remember what it is called.

it is also used in the fire services to refill S.C.B.A.'s
