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.

This article needs to show the facts, the uselessness of small scale "Gravity battery" compared to LiIon batteries. I have added simple calculation examples, from pendulum clock to person climbing stairs and King Kong in NYC, neither can match a simple battery. A bus load of scrap in a mine shaft is nearly as expensive as a matching battery.
Some notable people who have been claimed to be suppressed, harassed, or killed for their research are Stanley Meyer, [17] Eugene Mallove, [18] and Nikola Tesla. [19] Free energy proponents claim that Tesla developed a system (the Wardenclyffe Tower ) that could generate unlimited energy for free.
