Gravity battery

A gravity battery is a type of mechanical battery that stores gravitational potential energy, by raising a mass, allowing that energy to be released (typically converted to electrical energy via a generator), by allowing the mass to fall.

Such devices have been considered as part of an sustainability/renewable energy drives, addressing the problem of electrical energy storage.[1]

The technique was introduced with the pendulum clock.[2]

Similar devices have been proposed on a smaller scale to power a single light bulb in developing countries.[3]

For grid scale storage, weights suspended by cables may generate power as they drop to the bottom of the sea.[4] Heavy trains run uphill can release that potential by using regenerative braking going downhill.[5]
