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.
Fusion is the first step to a post scarcity world. All the new technology, products, agriculture methods, ect. that would be made possible with abundant, clean energy would completely transform the world. I doubt solar and wind could ever provide enough to make those advances.
