we create a special coating for based on nanoparticles that xmm are coated with a capsule of a radioisotopeurce in order to shift the radiation spectrum of a heated body to a shorter wavelength region, that is, a more visible spectrum . this allows you to increase the efficiency of converting the energy of nuclear decay of its electricity with the help of special photocells such a battery can last a very long time. which isotope you put so much and work, then 228 emits 2 years of plutonium 238 for almost 90 years. and if the source is made to be reconciled and 241, then an atomic source will continuously and safely provide electricity for longer. than the 400th anniversary? the idea of such a battery is that we put it once, either in the device or in the mechanism and forgot it. the entire period of operation of this device is provided by the energy of such a battery. the correct selection of isotopes allows, uh, to create an absolutely safe source of energy, uh, and those fission products can be protected by thin foil or even a sheet of paper. atomic batteries are not needed, recharging
