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.
The benefits of nuclear fusion could eventually power the world for everyone for free with no greenhouse gasses. Of course RnD is expensive, but that doesn’t mean it’s not worth it
