Abstract: A light cooling and heating machine, for which electrons or other charged particles serves as a refrigerant, comprising a light source and a sealed container. When cooling, the interior of the sealed container is filled with an electron gas, the light source produces an incident light, under the irradiation of the incident light, the radial attractive force among vibrating electrons reduces the average kinetic energy of the electrons for thermal motion, thus reducing the temperature of the electron gas and implementing cooling. When heating, the interior of the sealed container is filled with oxygen ions and helium ions, tinder the irradiation of the incident light, the radial repulsive force among the vibrating oxygen ions and vibrating helium ions increases the average kinetic energy of the electrons for thermal motion, thus increasing the temperature and implementing heating.

Abstract: A light-controlled superconductor uses electrons as carriers, which includes a light source and a sealed tube, wherein the sealed tube is made of glass or plastic. The sealed tube is filled with electron gas, and the light source produces incident light, and under the irradiation of the incident light, electrons will be forced to vibrate and behave similarly to vibrating electric dipoles, and emit secondary electromagnetic waves, so that the average distance between the electrons in the sealed tube is much smaller than the wavelength of the incident light, causing the vibrating electrons to be in a near-field of each other. When the electric field intensity direction of the incident light and the electric moments of two vibrating electrons are in the same radial straight line and are in the same direction, there exists an attractive force among the vibrating electrons.

Abstract: A refrigeration apparatus includes a compressor, two or more cylinders coupled with the compressor, and an airproof container enclosing the cylinders and filled with air or other gas. Each cylinder is provided with a piston, an inlet valve coupled with the compressor, and an outlet valve coupled with a condenser. When inlet valves are open, outlet valves are closed, and pistons move from bottom to top of cylinders, refrigerant flows from compressor into cylinders through inlet valves; and when inlet valves are closed and outlet valves are open, refrigerant flows from cylinders into condenser through outlet valves. Then, air pressure in cylinders drops, and pressure in airproof container forces pistons to move to the bottom of cylinders. The pressure in airproof container is utilized by cylinders to produce electrical energy.
