OpenStar Technologies is a renewable energy company that develops fusion reactors for baseload power to the grid. Its levitated dipole fusion technology is turning the tokamak design inside out. Instead of having plasma inside magnets, it has a magnet inside the plasma. Its reactor features a single, extremely powerful magnet levitating inside a vacuum chamber about 5 metres wide, which looks like a steel donut on legs. The design is modelled after the plasma in planetary magnetic fields, including Earth's. The advantage of this reactor is it's easier and faster to engineer than a tokamak.
