A 1,000kg, 5m, 200RPM flywheel would store 685,567J of energy if it was shaped like a disc. That''s 0.19kWh of energy — enough to boil the water for about seven (7) cups of tea or run a typical airconditioner for about 10 minutes. I think you might be over-estimating how much energy these things can store. – Tim.
