Indeed, fusion power was first experimentally demonstrated in 1952
(the first hydrogen bomb was tested on 1952-10-31).  And it had (very)
positive energy gain, too!

Oh, you wanted the apparatus to be last longer than a few nanoseconds,
and to be at least vaguely "safe" for nearby humans?  More engineering
details..... ;)
