Is your question rhetorical ? Because that's how ITER (nuclear fusion reactor) generate electricity in a nutshell, if you replace the ball by plasma. source :

  That diagram is about the energy inputs to heat the plasma. Energy output to generate electricity is quite indirect: hot neutrons escape the magnetic containment and are caught in a lithium blanket. This produces tritium from the nuclear reaction between the neutrons and lithium nuclei, and heat. The blanket is cooled with water which is used to drive a conventional steam turbine generator set. See the last paragraph of the reactor overview at http://en.m.wikipedia.org/wiki/ITER http://en.m.wikipedia.org/wiki/ITER and note that they do not plan to generate electricity from ITER: it is purely experimental.
