A thermoelectric generator consists of circuits arranged in parallel rows, in which thermocouples in adjacent rows are facing each other by the same-named junctions, forming alternating narrow zones of hot and cold junctions. At least one of the layers is a layer of thermal energy thermocouples, the repeatability of the rows of circuits of which is two times less than the repeatability of the rows of circuits of thermocouples generating electricity. Hot and cold zones between the rows of thermocouple circuits of all layers of thermocouples generating electricity and hot and cold junctions of the rows of thermocouple circuits of thermal energy are superimposed, respectively, by tight contact on each other by junctions and substrates, ensuring internal heat exchange between them. In addition, the generator is provided with an external heat supply circuit to the hot zone area and a heat removal circuit from the cold zone area.

A portable solar shower is a showering device that can heat the water in a tank to a user defined temperature, with the help of a large solar panel. In order to accomplish that, the device includes a thermostat that displays multiple temperatures, a vacuum insulated water tank that helps maintain the temperature of the water at the user defined temperature level for long hours, and a retractable showerhead and shower pipe. Further, the device is mounted over an upper surface of a vehicle, thereby not compromising any luggage or trunk space of the vehicle. The portable solar shower further includes a power unit that provides power to water pumps and all the necessary circuitry within the device. Furthermore, the device includes an additional smaller solar panel that can provide energy to the power unit, thereby enabling the user to run the shower unit on natural renewable sources of energy.

The present invention discloses a solar heating system for cyclic heating of a swimming pool, relating to the swimming pool heating technology. The solar heating system structurally comprises a swimming pool, solar heaters and a water pump. Compared with the prior art, a solar panel is mainly added, and the water pump is installed on a solar heater in an integrated way that the water pump is connected with not only the solar heater as a waterway, but also the solar panel as a power supply circuit. After the above-mentioned improvements, the whole solar heating system has the advantages such as a compact structure, convenient disassembly and assembly, and miniaturization. Since the solar panel independently supplies power to the water pump, the solar heating system can be used normally in an outdoor place far away from a mains socket. The application place is not restricted with wide application scope.
