Long Live the Cleantech Revolution

A note on Active Power: One of the reasons they are concentrating on back-ups is their cool-source design. They store compressed air over a long period of time; the quick changes are handled by flywheels, but a long outage draws on the compressed air, producing as a byproduct, cooling to take the place of the energy-using air conditioners. I'd like to see what could happen by combining their low-speed flywheels with a more efficient air storage, such as MDI's triple-expansion & heat transfer design!
