About Us

Princeton Fusion Systems is a small business focused on developing small, clean fusion reactors for both terrestrial and space applications.

The Princeton FRC reactor is built upon a foundation of over 15 years of research and experience at the Princeton Plasma Physics Laboratory, funded primarily by the U.S. DOE and NASA. It is our mission to develop the Princeton FRC reactor design into a portable, modular  power plant that can provide power in off-grid locations. From remote industrial applications to emergency power after natural disasters to off-world bases on the moon or Mars, the PFRC is the ultimate microreactor solution.

Our parent company, Princeton Satellite Systems, specializes in spacecraft control.
