Gravity Battery
- A gravity battery is a type of electricity storage device that involves lifting (charging) and lowering (discharging) a heavy weight.
- When there is plenty of green energy, the batteries use the power to lift a heavy weight (or blocks) either high into the air or to the top of a deep shaft.
- When electricity demand picks up, the blocks are lowered one by one, releasing kinetic energy that is used to rotate a motor and generate ....
