THERMIONIC ELECTRON ELECTRIC GENERATOR - 2026

The present disclosure relates generally to electrical energy conversion and generation. More particularly,the disclosure relates to integrated systems that convert energy from radioactive decay, ionizing radiation,thermal gradients, thermionic electron emission, microwave-frequency electromagnetic interactions,mechanical rotation, and electromagnetic induction into useful electrical output, microwave output, orboth. The disclosure also relates to magnetic control of charged particles, ionized-gas charge separation,radioisotope-heated thermionic emitters, magnetron-type microwave generation, brushlesselectromagnetic generators, power conditioning, waste-heat recovery, and cryogenic thermalmanagement. BACKGROUND Earlier embodiments of the Thermionic Electron Electric Generator family employed sealed electronemission structures, thoriated cathodes, ionized gases, magnetic fields, electrodes, cobalt-60-relatedradiation sources, electromagnetic coils, rotary electrical generators, thermocouples, and related energyconversion components. The 2026 disclosure reorganizes and improves those devices into a modulararchitecture in which distinct physical conversion mechanisms are identified and may operateindependently, sequentially, or in combination.The disclosed system does not depend on creation of energy. Instead, each embodiment receives energyfrom an identified source, including radioactive decay, heat, an applied electrical field, or mechanicalinput, and converts a portion of that energy into another useful form. The use of multiple conversionstages allows electrical output from different subsystems to be collected, conditioned, stored, or suppliedto a load. SUMMARY OF THE INVENTION In one embodiment, cobalt-60 or another radioisotope emits ionizing radiation into a conversion chambercontaining an ionizable medium. Radiation interactions produce ions and electrons, and electrodes collectseparated charge to provide electrical output. A magnetic structure may influence trajectories of chargedparticles, while a cryogenic or other thermal-management system removes heat deposited by radioactivedecay and radiation absorption.In another embodiment, radioactive-decay heat or another heat source raises an electron-emitting cathodeto a temperature sufficient for thermionic emission. Emitted electrons move toward an anode or collectorunder an electric field, optionally while a magnetic field focuses, confines, or redirects the electrontrajectories.In another embodiment, a thoriated thermionic cathode forms part of a magnetron-type microwavegenerator. Electrons emitted from the cathode are accelerated by an electric field and influenced by amagnetic field so that their trajectories interact with one or more resonant cavities. Microwave-frequencyelectromagnetic energy is extracted through a waveguide or other coupling structure.In another embodiment, a radioisotope heat source supplies thermal energy to a heat engine that producesshaft power for a brushless electromagnetic generator. In another embodiment, mechanical inputindependently drives the electromagnetic generator. Multiphase windings, permanent magnets, rare-earthmagnetic materials, electromagnets, axial-flux structures, radial-flux structures, rectifiers, regulators,inverters, storage devices, and common electrical buses may be employed.The disclosed subsystems may be combined in a single apparatus. Electrical outputs from radiationionization, thermionic, thermoelectric, microwave-conversion, and electromagnetic generator stages maybe supplied to a common electrical bus. Residual heat may be recovered in a secondary converter orremoved by a coolant loop, heat exchanger, or cryogenic cooling system.
