deuterium-tritium fuel

Deuterium-tritium fuel refers to a combination of two types of hydrogen isotopes used in nuclear fusion reactions. Deuterium is a stable form found naturally in seawater, while tritium is radioactive and can be produced artificially. When heated to extremely high temperatures, these isotopes fuse together, releasing a large amount of energy—similar to the process powering the sun. This fusion process has the potential to generate nearly limitless, clean energy with minimal environmental impact, making it a promising option for future sustainable power sources.
