+ THESISPOLICYDOE adds helium to the Critical Material List
DOE added helium to its Critical Material List, citing semiconductors, natural-gas leak testing and quantum computing. Helium also cools fusion magnets and high-temperature gas reactors. Affects Fusion.
+ THESISFUNDING · EOS STELLARATORThea raises a $100M Series B to site and build Eos

thea.energy →+ THESISHow it works
Also a ring of magnets, but twisted, so the coils alone shape the plasma. No current has to be driven through the plasma, which makes steady operation easier; the coils are harder to design and build.
