Flywheel based energy storage? : r/SolarDIY
Another huge problem is that flywheels have a very linear if not exponential power loss curve - the more RPMs you use up to generate power the less it power it has left to offer. IE, 50% reduction in RPMs is more like 70-90% of the power gone. When you''re at 50% of the flywheels rated RPM it''s more like there''s only 10-20% of the available ...
