A better energy storage device? - 04/13/13 01:49 AM
Phys.Org:The Velkess Flywheel: A more flexible energy storage technology
This new flywheel energy storage system uses inexpensive fiberglass in the flywheel instead of carbon fiber. That reduces the cost enormously. The current prototype handles about 2 KW of power. They are working on increasing it to be able to handle 25 KW, so that it can be used as an off-grid backup. There are some technical issues. It spins at extremely high speeds and uses very strong magnetic bearings. They hope to be able to get it working before very long.
