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 order to get the energy output of a fusion reactor with renewables you would have to have millions and millions of solar panels you don't think that's expensive?

It also will take up a ridiculous amount of space.

Cost-per-Killowat for a Fusion reactor is ~$6,000, Cost-per-Killowat for solar photovoltaic is ~$1,000
