The dream of fusion power has been a long-held one, but it may be a step closer to becoming a reality. Researchers at General Atomics, a company based in San Diego, California, have discovered a way to make the magnetic containment fields used to hold the plasma in place less susceptible to rupture, which means that critical components will have to be replaced less often, making the financial overhgeads much smaller. There are hopes to install this new system in the prototype International Tokamak Experimental Reactor being built in France.
