A nuclear fusion startup backed by billionaire Jeff Bezos will build its first pilot power plant outside of London, potentially accelerating a new way of generating clean energy.

Canada’s General Fusion Inc. is one of about two dozen startups trying to harness the power that makes stars shine. Rather than splitting atoms like in traditional fission reactors, fusion plants seek to bind them together at temperatures 10 times hotter than the sun. Doing so releases huge quantities of carbon-free energy with no atomic waste.
