Gravity ''batteries'' might help a weighty renewable-energy problem
Gravity power plants are all based on that same idea: Lift something heavy to increase the gravitational potential energy. When the weights drop, their potential energy goes down, the kinetic energy goes up — and turbines spin to generate electricity.

Gravity battery
Pendulum clock driven by three weights as "gravity 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-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/3600 of a Watt-hour [Wh], while a typical Lithium-ion battery 18650 cell [2] can hold about 7 Wh, thus 2500 times more at 1/20 of the weight.
