Renewable energy to be stored in floating flywheels

Better magnets can help store renewable energy from solar cells and wind turbines in magnetic flywheels. The new technology for energy storage could help remove one of the really big obstacles to further distribution of renewable energy. Innovation Fund Denmark is investing DKK 12 million in the project.
