Radioisotope thermoelectric generator

A Radioisotope Thermoelectric Generator (RTG) is a type of power generator that converts heat released by the decay of radioactive isotopes into electricity through thermoelectric conversion. RTGs are used primarily for space missions, remote weather stations, and other applications where conventional power sources are impractical. ### How It Works: 1. **Radioactive Decay:** The RTG uses a radioactive material, typically plutonium-238, which emits heat as it decays.
