A nuclear power battery, also known as a radioisotope thermophotovoltaic (RTPV) generator, is a compact device that converts heat released from radioactive decay into electrical power.
It contains a small amount of radioactive material, such as plutonium-238, which emits heat as it decays. This heat is then used to generate electricity through thermophotovoltaic cells, producing a continuous and reliable power source. These batteries are often used in space exploration, remote locations, and certain medical devices due to their long-lasting and efficient energy production.
