Nuclear fusion reactor. Hot plasma swirling inside the core of a nuclear fusion reactor. The plasma (white) is being compressed by a magnetic holding bottle. Nuclear fusion, which also occurs in the Sun, releases large amounts of energy and is cleaner than nuclear fission, since it doesn't produce radioactive waste.
