Realta Fusion develops fusion energy technology for the production of industrial heat and power. Its magnetic mirror confines a plasma between two high field superconducting magnets. The strong magnetic fields cause charged, energetic particles to bounce back and forth, also known as the mirror effect. The technology uses ion and electron RF heating with high energy neutral particle injection to optimize plasma performance. The startup was the first to successfully power a light bulb using the WHAM demonstration fusion reactor. The power converter is installed at the end of the reactor and generates up to several amperes of electricity at 100 volts.
