Type One Energy uses an enhanced version of a 1957 experimental Stellarator invented by US scientist Lyman Spitzer. The co-founders of Type One Energy built the world’s first optimized stellarator at the University of Wisconsin-Madison in the 1990s and conducted foundational stellarator research on it in the early 2000s. Using non-planar, high temperature superconducting magnets to optimize plasma flow, Type One Energy can surpass all fundamental technical barriers to achieving fusion energy at commercial scale. The company is building Infinity One prototype together with the 400 MWe Infinity Two fusion power plant. It plans to buildthe first power plant by 2034
