Of course, another fun way to stellify Jupiter is to drop one or more
small black holes into its atmosphere. Just putting one into the core would
heat it up quite a bit once it got large enough, but having a swarm
orbiting in circular orbits in the higher layers might be even better:
they absorb matter and radiate plenty of energy, and the hard radiation
is absorbed by the atmosphere and reradiated as heat. This might even
work for a longer time than a single "Jupiter into hole" detonation (but
that would be *impressive*: at first the core would heat up, and probably
expand, causing new weather patterns. Then the whole planet would begin
to heat up, and then the hole would begin to grow exponentially as the
planet simultaneously exploded and imploded).
What I would like to hear if anybody knows how to calculate how much
matter does flow into the hole, given that the temperature of the
accretion disc is going to blow away a lot of matter too; I guess a state
develops where radiation pressure and gravity balances each other.

Is the visible range the best? I envision building tiny dyson spheres
around singularities kept in place with electromagnetic fields and fed
garbage matter so as not to grow to hot or cold.

I think using grasers focused on a point was how Crane suggested it
could be done. Bosons is probably the way to go, but they tend to be
rather light. Maybe a Bose condensate could do the trick? The energies
needed are large, but not impossible to come by if you have a dyson shell
at your disposal. And once you have your hole factory, then you can bathe
in energy...
