Tessera Fusion
Tessera Fusion
Deuterium-helium-3 with direct energy recovery and no steam cycle. Accredited investors only.
Deuterium-helium-3 releases most of its energy as charged particles rather than neutrons, which means the energy can in principle be recovered electrostatically instead of by boiling water. That eliminates the turbine, the steam plant and much of the neutron damage problem. It also requires higher temperatures than deuterium-tritium and a helium-3 supply that does not meaningfully exist on Earth.
