Venture capitalist says nuclear fusion is coming

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.

"Within five years, large companies will start to think about building fusion reactors," Wal van Lierop, CEO of Chrysalix Energy Venture Capital, said in an interview at the Clean Tech Investor Summit taking place here this week. In three to four years, scientists will demonstrate results that show that fusion has a 60 percent chance of success, he said.

Lierop has backed General Fusion's Magnetized Target Fusion (MTF) model. An electric current is generated in a conductive cavity containing lithium and a plasma. The electric current produces a magnetic field and the cavity is collapsed, which results in a massive temperature spike. MTF has an advantage over other fusion techniques in that the plasma only has to stay at thermonuclear temperatures (150 million degrees Celsius) for a microsecond for a reaction to occur.
