General Fusion’s system, with its piston-studded spherical chamber, has an industrial look about it. Hundreds of powerful pistons, driven by steam, will push down on a liquid metal liner, which in turn pushes on a plasma of superhot hydrogen gas, compressing the fuel to fusion conditions. Underneath the pragmatically industrial exterior, however, are cutting edge electronics that give these pistons an incredible level of control.

By Dr. Michel Laberge, Founder & Chief Scientist, and Michael Delage, Chief Technology Officer at General Fusion. General Fusion has focused a lot of effort on plasma technology over the past few years, and that investment is now paying off. For those of you who don’t spend all day playing with plasma, here’s a quick reminder of what it is: plasma is the superheated gas that is the fuel for a fusion power plant. Controlling the behaviour of plasma is widely considered one of the most difficult aspects of fusion. General Fusion is a leader in the development of plasma, specifically a type of plasma classified as “self-organizing”, and has set some world records along the way. Today we’re going to have a look at how this has been progressing.
