"When you have" meaning of course "If you had". As to the chances of
the hypothetical ever becoming true, the best candidates for me are
nuclear fusion, space power satellites, and deep geothermy.

Nuclear fission is a so-so, and the rest is IMHO a joke, unless for
very specific and limited purposes.
