 Magnetic confinement fusion

Once again, relies on superconductivity to reach insane magnetic fields. Superconductivity is just so important.

Ciro Santilli saw a good presentation about it once circa 2020, it seems that the main difficulty of the time was turbulence messing things up. They have some nice simulations with cross section pictures e.g. at: www.eurekalert.org/news-releases/937941.

Magnetic confinement fusion (MCF) is a method used to contain and control nuclear fusion reactions using magnetic fields. It is one of the leading approaches being researched to develop practical and sustainable nuclear fusion as a source of energy.
