Company develops compressed air storage for wind power

This looks like it could be a viable alternative to batteries for storing energy. Wind turbines compress air rather than making electricity directly. -- Jeff g.
"The high-pressure pipeline network collects and stores 6-12 hours of energy. If the project is sited near a geologic feature such as a salt dome, aquifer, limestone cavern, or depleted gas field, energy storage times can exceed a month."

It's becoming increasingly clear that it is extremely difficult to make batteries sustainably. And it will be near impossible for the average person to maintain them after Peak Oil. This is a great development in energy storage! (I also like the elegance of air-powered turbines transferring that energy back into air :)
