The scientists used lasers to fuse two light atoms into a single one, releasing 3.15MJ (megajoules) of energy from 2.05MJ of input – roughly enough to boil a kettle.
Why do we even study this? Renewables are the only way. This is a waste of money which is a finite resource.
Renewables are already well researched. It’s up to governments to enforce their use if they want.
Fusion can be huge because it can theoretically be scaled up significantly.
Even though both this reactor and ITER have small energy production goals, if they can get a reaction to run for a usable period of time, then it becomes something worth investing into to improve.
Even the USA chucks money at it because it could have military use. Fission power started in a similar way.
