Fusion

Fusion could solve the world’s energy problems and curb climate change, says physicist and Everest-conquering adventurer Melanie Windridge, who reveals some of the latest innovations. I work with a fusion start-up called Tokamak Energy, which is aiming to show the commercial feasibility of fusion by 2030. We have an experimental machine called the ST40, which is a spherical tokamak. Tokamak reactors are the best performing fusion device that scientists have come up with so far. The reaction chamber is a torus shape, a bit like a ring doughnut, though ST40 is squashed up like an apple. The world’s biggest fusion reactor, ITER, being built in France, is a tokamak machine, but we want to use advanced superconducting magnets to bring the size down.
