Nuclear fusion record smashed as German scientists take 'a significant step forward' to near-limitless clean energy


Germany's Wendelstein 7-X stellarator has set a new benchmark for fusion reactors, bringing commercial, near-limitless clean energy one step closer to reality.

A recently concluded experimental campaign at the Wendelstein 7-X stellarator at the Max Planck Institute for Plasma Physics (IPP) in Greifswald, Germany has smashed previous fusion records and set a new benchmark for reactor performances. By smashing together isotopes (or different versions) of hydrogen at incredibly high temperatures, the resulting superheated plasma of electrons and ions fuses into heavier atoms, releasing a phenomenal amount of energy in the process. However, while this fusion reaction is self-sustaining under the extraordinary temperatures and pressures within stars, recreating these conditions on Earth is a huge technical challenge — and current reactor concepts still consume more energy than they are able to produce.
