Helium-3 (2 protons 1 neutron) fusion requires much higher temperatures and
pressures to work then the more conventional Deuterium (1 proton 1 neutron)
Tritium (1 proton 2 neutrons) fusion. The big advantage of Helium-3 fusion
is it doesn't produce high speed neutrons that can damage the machinery and
induce it to become radioactive; instead Helium-3 produces high speed
electrons which don't damage machinery, can be easily controlled, and are
easily converted directly into an electrical current so there is no need to
use steam or even have a mechanical generator, thus it would have an
extremely high conversion efficiency.
