Environmental energy conversion device

Abstract

The invention discloses an environmental energy conversion device which comprises an energy conversion unit, wherein the energy conversion unit comprises a positive pole, a negative pole and an intermediate; the intermediate is made of a semiconductor and is clamped between the positive pole and the negative pole, and two sides of the intermediate are respectively contacted with the positive pole and the negative pole; and the positive pole and the negative pole have asymmetry. The asymmetry of the positive pole and the negative pole refers to that the materials of the positive and negative poles have different work functions or different surface modification or different geometric structures; and the energy conversion unit can be connected in parallel and in series to form a whole environmental energy conversion device. The surface effect of the semiconductor is utilized, so that the environmental heat energy is continuously converted into electric energy in an environment, such as gas, liquid, gel or plasma, contacted with the semiconductor, particularly in solution, and a cooling effect is achieved. The environmental energy conversion device can be used for power generation and refrigeration, provides energy and refrigeration for various building constructions, transport equipment or electronic equipment, and can be used for concentration, temperature and flow velocity detection devices.

Description

technical field [0001] The invention relates to environmental energy conversion equipment of a new principle. Background technique [0002] Energy conversion and storage technologies include conversion of solar, thermal, vibrational, chemical and wind energy into electricity. Among these numerous energy conversion technologies, lithium batteries, supercapacitors, solar cells, fuel cells, and ZnO nanogenerators have received the most attention. However, lithium batteries and supercapacitors need to be charged before they can be used, and in order to increase energy density, they need a large volume and weight. Solar cells need light to be used. Fuel cells consume fuel and cause great harm to the environment. Zinc oxide nanogenerators produce discontinuous electrical output, and capacitors are needed to store the generated electricity, which also consumes Mechanical energy. However, there is another form of energy, the energy of thermal motion of molecules, atoms, ions, and...

However, lithium batteries and supercapacitors need to be charged before they can be used, and in order to increase energy density, large volume and weight are required

Solar cells need light to be used. Fuel cells consume fuel and cause great harm to the environment. Zinc oxide nanogenerators produce discontinuous electrical output, and capacitors are needed to store the generated electricity, which also consumes Mechanical energy

However, there is another form of energy, the energy of thermal motion of molecules, atoms, ions, and particles. For example, the thermal motion speed of gas molecules is as high as 1000 m / s, and the energy of thermal motion of ions in aqueous solution at room temperature is as high as 300 m / s. Because this movement is chaotic, so far there is no report of converting the energy of this thermal movement into electrical energy.
