Gravity induced temperature difference device

Abstract

A method and apparatus for creating temperature differences in columns of gases, liquids or solids in a closed system under the influence of gravity is used to provide energy in the form of electricity or heat. A temperature differential element, optionally a solid, liquid or gas, is suspended vertically in a chamber inside an enclosure. The chamber optionally is either evacuated, filled with fibers, powder or small spheres, or otherwise arranged to minimize the effects of convection currents and radiation. Under the effect of gravity, the upper end of the temperature differential element becomes cooler than the lower end. A thermocouple can be used to generate electrical energy from the temperature difference between a vertical segment, for example the upper and lower ends, of the temperature differential element, or heat exchangers used to extract heat.
