Revolutionary 1950s Tech May Solve Fusion Energy Grid Integration.

Scientists are revamping reactor designs from the 1950s and ‘60s in hopes of launching fusion plants in the coming decades. One oddly shaped set-up, the stellarator, has attracted recent attention from scientists and startups alike. The stellarator has a few key advantages over the tokamak, including the ability to sustain plasma for long periods of time and not requiring a strong electric current to help induce the magnetic field that contains the plasma. Several startups want to tackle this physics challenge, including New Jersey-based Princeton Stellarators and Wisconsin-based Type One Energy.
