Vacuum for Energy Storage

To ensure the efficiency of a flywheel as an energy storage device, the constant losses through friction have to be reduced to a minimum. To do so, the flywheel housing is evacuated with vacuum pumps. Typical targeted pressures are 1·10-1 hPa down to 1·10-3 hPa or even less. As a result, both heat generation and energy losses are drastically
