>I'm guessing if compressed air makes it to the global market,
>it will be as part of an air/electric hybrid.
the hybrid will be in the form of an auxiliary heat source to further expand the compressed air. the electricity will be used to compress the air, either locally (home A/C) or centrally via fueling stations. The heat can be from any burnable source making it a very flexible design for global and developing markets.
Lots of information out there on MDI site as well as ZPM.
