This invention discloses a charge generation device and method based on potential difference, belonging to the field of energy conversion technology. The spatial layout of the device is completely isomorphic to the Earth's latitude and longitude system: a stationary heat storage body is at the center, surrounded by a sealed medium cavity, a stationary thin shell, and moving parts. The upper part is the North Pole, with a positive charge lead-out end, and the lower part is the South Pole, with a negative charge lead-out end. The radial temperature gradient established by the heat storage body drives medium convection. The moving parts horizontally surround and reinforce particle collisions along the latitudinal direction, generating electricity. The inner surface of the stationary thin shell is divided into upper and lower hemispheres, naturally separating positive and negative charges based on the difference in the material's work function. Positive charges accumulate along the meridian from bottom to top to the North Pole, and negative charges accumulate along the meridian from top to bottom to the South Pole, naturally outputting direct current. This device does not rely on permanent magnets, a through-axis, or magnetic flux cutting conductors; it can directly utilize low-grade thermal energy as the main energy input. The system follows the law of conservation of energy; thermal energy contributes the main part of the input energy, and artificial mechanical work serves only as an auxiliary condition, enabling the output electrical energy to exceed the artificial mechanical input power. The core topology can be flexibly scaled to adapt to a variety of low-grade heat recovery and independent off-grid power supply scenarios, ranging from residential to industrial applications.
