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.
So? The trick is to keep developing the technology, not give up because it doesn’t immediately deliver unlimited energy.
We’ve been working on fusion in one form or another for nearly 100 years. We’re still nowhere near turning it into a useable energy source. I don’t really care if research continues or not, I’m sure the research can be useful in other areas but fusion is not going to save us.
