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.
I downvotes solely for OP’s comment. Nuclear energy has its place, if magically we had enough solar and wind farms constructed and even the grid built that connects the whole world, all of it magically just appearing. We will still not be able to retire fossil fuel power generation immidiately because we don’t have a storage technology that scales well enough atm and renewable can’t cover baseload as they can’t generate 24x7 output.
