Yet another attempt at a
productive fusion reactor, although this one is funded by the
Department of Energy.
Shiva uses a large
hollow steel sphere filled with a
liquid medium of some sort. Nine
quarter-
mile long
lasers are positioned
equidistantly on various
axes around the
sphere, and all are aimed at a
precise point in the
center. When the lasers are fired, a
pellet containing
deuterium is dropped into the focus of the lasers. It then
fuses and
heats the liquid medium and
yadda yadda yadda you get the idea.
Unfortunately, it has yet to produce an
appreciable amount of
energy beyond that needed to power the lasers, and is thus not productive.
