Abstract

The Thermal Electric Generator (TEG) includes a high efficiency multi-layer semiconductor device adapted to enable heat, over a wide temperature range, to be converted into useful power. This is not a simple solar panel. The “heat” referred to here can be from radiation or any other convection or conduction source. One important aspect is that the TEG not only works in a “solar” environment, but is more particularly adapted to recover energy from heat generated by electronic components and circuits, mechanical rotating equipment and machinery, waste energy, furnaces, geothermal, etc. This heat comes in the form of released electrons, thus, the invention is based on the concept of fluctuation voltages and the conversion of the same into useful energy, which translates into an increased efficiency of over 50% compared to the peak existing efficiency (i.e., 16%) of existing solar panels
