This method of energy storage keeps popping back into my mind.
Some quoted excerpts from a few of my previous postings:
Flywheel energy storage is a more efficient, pollution-free solution to chemical batteries. Total recharge can be accomplished in about 15 minutes at any rate of energy draw or frequency yielding a cycle life of over 100,000 charges, or 30 years, with no deterioration in performance.

So far no big auto manufacturer has picked up the option to incorporate Bitterly's design into their models. Meanwhile, there is considerable interest in Bitterly's flywheels powering satellites in space and trains in Germany. He also has a static model in the works that could be used as a back-up power generator. In the event of a power failure, it could assume the load within nanoseconds, thus preventing valuable computer data from being lost.
How long do Bitterly's flywheel systems last? He has designed the system to survive at least 10,000 run-and-recharge cycles. Under normal conditions, that would mean a life of 27 years -- and that's only a lower limit. flywheel systems last? He has designed the system to survive at least 10,000 run-and-recharge cycles.

Cause of Death: Major car manufacturers' rejection of new, flywheel-based engine technology
In August 1996, brothers Benjamin and Harold Rosen summoned a throng of journalists and auto executives to the remote Mojave Desert, in California. The founders of Rosen Motors had spent three years developing a hybrid electric vehicle. Now they were ready to debut their version of the car of the future. As the road test began, the spectators craned their necks in anticipation.
With their company entering a costly crash-testing phase, and with automakers in Detroit and overseas unwilling to bankroll it, the Rosens decided to call it quits, putting their 70 employees out of work. Reinventing the automobile turns out to be as difficult as it sounds--even for Ben Rosen. http://boatdesign.net/forums/showpos...&postcount=198
