“They heat up the outside; that creates a shockwave.”Even though getting a net energy gain from nuclear fusion is a big deal, it’s happening on a much smaller scale than what’s needed to power electric grids and heat buildings.The missing mass converts to an enormous amount of energy.The neutrons, which are able to escape the plasma, then hit a “blanket” lining the walls of the tokamak, and their kinetic energy transfers as heat.This heat can then be used to warm water, create steam and power turbines to generate power.“We need to bring the cost down by a huge factor.”However, Chittenden called this new chapter in nuclear fusion “a true breakthrough moment which is tremendously exciting.”Roulstone said there’s much shows more work needs to happen to make fusion able to generate electricity on a commercial scale."
