You gotta say what kind of battery when you make a comment like that. A bottle of pressurized gas is a battery. Not very polluting though.

Sure you can buy a compressor and some air tanks. I imagine the turbine you need to purchase might be midly expensive. The real issue I think would be the size of the pressure vessel you would need to make it worth it.

Right. That's why this method is used at large scale in salt mines.
