Abstract
Systems, methods, and devices of the various embodiments described herein enable an energy conversion system comprising a radioactive element for generating conduction-band electrons in an avalanche cell and generating heat, wherein the conduction-band electrons are provided to an anode to generate avalanche cell power, and the heat is provided to a thermoelectric generator to generate thermoelectric power. In an embodiment, the avalanche cell is irradiated with gamma rays, which excite electrons within the avalanche cell, generating a current. In an additional embodiment, the thermoelectric power and avalanche cell power can comprise a dual power system.
