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.
Fission requires insanely costly wastes management. It is very dangerous and security is a huge costs-contributing factor. This is not the case with fusion, so costs might be lower despite complexity.
