Abstract
In areas where wind power, hydro power and earth heat power are all available and are to be developed, a common means and method of storing such power during off peak periods of power use are frequently required. Here power storage is accomplished by the lifting of under ground weights. Earth power may be geothermal heats, volcanic heats, heats from hot springs, deep holes in the earth, or heats from deep oil or gas wells, such as come to the surface when they bring up oil or natural gas. These are all here combined as a common source of power. Any or all may contribute power to the power storage.
