The Wendelstein 7-X, an experimental nuclear fusion reactor in Germany, has broken the world record for fusion performance in a stellarator. In 2015, Science took a look at how it came together: https://scim.ag/2me54lZ | Science

Germany is pushing forward in nuclear fusion research through advanced experimental reactors such as tokamaks and stellarators, aiming to achieve stable plasma confinement and eventually net energy gain. These machines recreate Sun-like conditions on Earth by heating plasma to extreme temperatures and holding it in place with powerful magnetic fields. Fusion is often called the “holy grail” of clean energy because it could provide abundant electricity with zero carbon emissions during operation
