Princeton Fusion Systems

Princeton Fusion Systems is a niche company dedicated to constructing small, environmentally friendly fusion reactors for use both on Earth and in space.

The Princeton FRC reactor, their flagship product, is the culmination of over a decade and a half of research and expertise at the Princeton Plasma Physics Laboratory, primarily funded by the U.S. Department of Energy and NASA. Their objective is to advance the Princeton FRC compact fusion reactor into a transportable power station capable of delivering power in remote areas and as part of modular power plants. Whether it's for remote industrial use, emergency power during natural calamities, or for lunar or Martian outposts, the PFRC stands as the ultimate solution in microreactor technology.
