But there's been progress. The sun's been doing fusion for a while, we made fusion bombs in the 50s, the JET torus near Oxford produced fusion output at 16 MW from an input of 24 MW of heating in 1997, and one of the MIT's proposed designs is projected to produce 200MW net power output if built.

So it's coming along even if commercial viability may still be a while off.
