technical field [0001] The invention relates to thermostatic power generation technology, in particular to a thermal-temperature-magnetic-shaped four-gradient coupled high-efficiency thermoelectric direct power transfer device and a power generation method. Background technique [0002] Electric energy is currently the most widely used and most convenient energy. Therefore, people are studying how to convert other forms of energy (such as fossil energy such as kerosene, wind energy, light energy, hydraulic energy, ocean energy, geothermal energy, biomass energy, etc.) into electric energy in an environmentally friendly, efficient and low-cost manner. . [0003] Most electrical energy today comes from thermal energy. However, the process of converting heat energy into electric energy still adopts the traditional intermediate vaporization power process with complex process and huge equipment system. The basic general process is: 1. Production of heat energy (fossil energy s...
