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…
Learn MoreThe storing of electricity typically occurs in chemical (e.g., lead acid batteries or lithium-ion batteries, to name just two of the best known) or mechanical means (e.g., pumped hydro storage).

Learn MoreLithium-ion batteries currently dominate the energy storage market, but these are better suited for short-term storage, says Hunt, because the charge they hold dissipates over time. To store sufficient energy for months or years would require many batteries, which is too expensive to be a feasible option.
