Atomic battery
| An atomic battery, also known as a radioisotope battery or radioisotope thermoelectric generator (RTG), is a type of battery that uses the heat generated by the radioactive decay of a radioisotope to produce electricity. This technology is primarily used in applications where long-lasting, reliable power is required in remote or extreme environments, such as spacecraft, deep-sea probes, and remote weather stations.
| The most common radioisotope used in atomic batteries is plutonium-238, which has a half-life of about 88 years. The heat produced by the decay of the radioisotope is converted into electricity using a thermoelectric generator, which consists of a series of thermocouples made from materials with different thermal properties. As one end of the thermocouple is heated and the other is cooled, a voltage is generated across the material, producing electricity.
| Atomic batteries have a number of advantages over conventional batteries, including a long lifetime (often measured in decades), a stable power output, and the ability to operate in extreme temperatures and environments. However, they also pose potential risks due to the radioactive materials used, and their disposal must be carefully managed to avoid environmental contamination.

| So a battery that will last 50 years. Sounds interesting though I dont see any big trusty channels say anything about it. Can anyone pour information on this topic?
