Whatever happened to kinetic electrical energy battery used flywheels in a vacuum?
I used to hear about the possibility of making kinetic energy battery, which can store large amounts of electricity on a Spinning flywheel running in a vacuum. I think there even measures to make the flywheel Spinning out of carbon fiber to them harmlessly bird-nest in the event of a crash. They still are built?
it would be magnetically levitated to reduce friction?
