Problems solved by technology

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 motion is chaotic, although in the field of scientific research, there is no report of converting the energy of thermal motion into electrical energy, but the energy of this thermal motion is converted into electrical energy in nature, but it happens all the time, such as lightning
