thermonuclear fusion

Thermonuclear fusion is the process where light atomic nuclei, like hydrogen, combine at extremely high temperatures and pressures to form heavier nuclei, such as helium. This fusion releases a tremendous amount of energy, similar to what powers the sun. Achieving controlled fusion on Earth involves heating fuel to millions of degrees, creating conditions where nuclei can overcome their natural repulsion and fuse. If harnessed efficiently, fusion offers a nearly limitless, clean energy source with minimal environmental impact, making it a promising solution for sustainable power in the future.
