He's not talking about unviable Tokamak designs (http://en.wikipedia.org/wiki/Tokamak), but something much simpler. Basically use H-bombs (which are the only tried and tested fusion technology) to drive a large internal combustion engine. The energy released by each explosion is stored by using it to lift water back into hydraulic dams.
[1] Just as all problems in computer science were solved (in principle) at Xerox PARC in the 70s, all energy problems were solved (in principle) at Los Alamos in the 50s.
Kardashev Level I (http://en.wikipedia.org/wiki/Kardashev_scale)
Dyson fusion engines.

Kardashev Level II
Dyson rings and shells (http://en.wikipedia.org/wiki/Dyson_shell).
Kardashev Level III
"Lather, rinse and repeat" with Dyson shells.
