The energy, no matter what its final form (air pressure) has to come from somewhere. And in the end, that source of origin is fossil fuel (except for solar cells.) This is just replacing a battery with an air tank.

Understood. It's a matter of effiency in my view. Less cost. I'm not praise the Goremind. I'm just thinking of our long-term security (both economically and physically).
Algae fuel would be the best alternative, although costs are too high...at the moment. I do believe our economy will be algae-driven in the future, if all things go well. That or fusion...but I think fusion is the DREAM.

Nuclear, wind, tidal ...
