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-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/360 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 climbing a 250m building, and falling down, equal…

Energy from a source such as sunlight is used to lift a mass such as water upward against the force of gravity, giving it potential energy. The stored potential energy is later converted to electricity that is added to the power grid, even when the original energy source is not available. A gravity battery is a type of energy storage device ...
Energy storage capacity. To analyse the energy storage capacity, the potential energy of the piston can be stated as (1) E = mgh, where m is the mass in kg, g is the gravitational constant (9.81 m/s 2) and h is the height.
