Gravity battery
OverviewTechnical backgroundDevelopmentMechanisms and partsTypes of gravity batteriesEconomics and efficiencyEnvironmental impactsGravity (chemical) battery
An old and simple application is the pendulum clock driven by a weight, which at 1 kg and 1 m travel can store nearly 10 newton-meters [Nm], joules [J] or watt-seconds [Ws], thus 1/3600 of a watt-hour [Wh], while a typical Lithium-ion battery 18650 cell can hold about 7 Wh, thus 2500 times more at 1/20 of the weight. A 100 kg human would have to climb stairs of ten floors (25 m) to match the little battery cell. A 10 ton King Kong
