Abstract
The present disclosure is directed to an energy extraction device that employs a radioactive isotope, such asSr, as a charged particle source. The decaying radioactive isotope emits energetic charged particles, such as beta particles, into a magnetic field. Because the magnetic field is substantially normal to the paths of the charged particles, a force is induced on the charged particles normal to both the path and the magnetic field. The induced force causes the charged particles to assume circular paths, forming a circulating charged particle beam that is contained within a structure. The circulating charged particle beam emits cyclotron radiation. The structure includes one or more rectennas around the interior wall which convert the cyclotron radiation to electrical energy as a direct current voltage.
