Abstract: Taking advantage of numerous sources of fueless energy such as the heats of volcanoes, hot springs, active and inactive oil and natural gas wells, geothermal heats and other natural steam power, some of these energy sources intermittent, and others continuous, are here combined to provide a steady flow of continuous fueless power for stationary or movable power plant use. It saves fossil fuels for uses far more important than their combustion, and does not pollute our human environment.
