Or gears.

  How do gears help? The potential energy capacity of the system is the weight (mass x gravity) multiplied by the altitude. Gears only impact the power input/output. Use gears on the way in and you can "charge" the battery with very little power (but it takes a long time). Use gears on the way out and you can discharge the battery very slowly, but get very little power out of it.
