A gravitational based energy storage system including a mass moveable within an underground well to release or store energy generated from other sources such as from wind turbines. Preferably the system includes pipes forming a hydraulic U-tube with one side filled with a dense liquid-solid mixture 11 and separated from and a runner liquid 5 in the other tube by a seal 15. The liquid-solid mixture may be in the form of iron or steel cylinders (Figs 10-13) or a mixture of spherical elements, power and a liquid. Preferably the liquid component is a low melting point alloy, a bismuth alloy or a fusible alloy which may be heated by geothermal heat or by waste heat from the potential energy transformation process. Alternatively the liquid component may be a mercury alloy. |
