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.
If it’s not geothermal or nuclear, that energy probably came from the sun one way or another.
Geothermal and nuclear came from the previous sun.
