A picture from the patent filing for what General fusion is trying to build with backing from Chrysalix Energy Venture Capital. GF will build a ~3 meter diameter spherical tank filled with liquid metal (lead-lithium mixture). Rams use compressed steam to accelerate pistons to ~50 m/s. Make compression wave in the liquid metal. Microsecond of fusion once per second. Note: This could be considered like a variant of "steam punk nuclear fusion" made real if it works.
