That would not be efficient. Yes you could also store the energy by pumping water up hill and letter it turn a turbine later, but you'd lose a LOT of power. Yo

You could store the energy in springs ala the da Vinci cart, but again not efficient.
All of these methods require a conversion, where as a Battery, Capacitor, or Leyden Jar will store DC as DC.
- dannypgh 12y agoConverting electric power to and from a battery requires an electrochemical reaction to occur. That is a conversion just the same - I don't really buy this "no conversion required" argument, just because you started and ended with direct current. Flywheels aren't some hypothetical means of storing power, either - they've seen a lot of exciting R&D over the last 15 years, and there are operators of grid-scale flywheels. e.g. http://beaconpower.com/ http://beaconpower.com/ http://en.wikipedia.org/wiki/Flywheel_energy_storage http://en.wikipedia.org/wiki/Flywheel_energy_storage
