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.
In the way the other poster compared them? Yes, in so far as people who complain “the new, developing technology isn’t immediately as optimised and refined as I want it to be” for both.
