Fusion is a nuclear reaction in which two or more atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process.
Fusion involves combining two or more atomic nuclei, while fission involves splitting a single atomic nucleus into smaller nuclei. Fusion also typically releases more energy than fission.
Yes, fusion has the potential to be a nearly unlimited source of clean energy. However, it is currently challenging to control and sustain fusion reactions on Earth.
Fusion energy has the potential to provide a nearly limitless supply of clean energy without producing greenhouse gas emissions or long-lived radioactive waste. It could also decrease our dependence on fossil fuels and reduce the risk of nuclear accidents.
The main challenges facing fusion research are finding ways to control and sustain fusion reactions, developing materials that can withstand the extreme temperatures and radiation of a fusion reactor, and finding a way to make fusion reactions produce more energy than they consume.
