'Breakthrough in nuclear fusion'

Interesting the BBC have this as their main news story (on now).

Distraction perhaps from the govt clusterpegginhg everyone.....

People would say the same if BBC ran with the new migrant laws the government have introduced

That reaction produced 17 kilojoules of energy.

This one produced 3.1 megajoules (3100kj). Significantly higher than 2014.

If it’s taken 8 years to upscale it from producing enough energy to boil a teaspoon of water to boiling a whole kettle, the prospect of generating enough energy to power a city (or even a village) is some way off.

Excuse me if I don’t get excited.

“Just now, Dr Marv Adams was holding up the cylindrical target containing the “peppercorn-sized” pellet of fusion fuel.

He confirmed they had achieved “ignition” of a fusion reaction.

He also revealed the scientists put about 2MJ of energy into their fusion reaction and got about 3MJ out.

That’s the evidence of the “energy gain” that this announcement is all about.

That’s the significant scientific milestone: proving a fusion reaction itself can generate more energy than you put into in.

But they had to use 300MJ of electricity to power up their lasers.

So from an energy production point of view, they're still having to put in 99% more power into the machine as a whole as they are getting out.”

Yes, the lab has made its own definition of net energy in order to claim the milestone (probably to get more funding)

It’s still a good step forward but not worthy of being headline news around the world.

There’s a lot of different versions of net energy gain.

There’s this one - power out is more than power in.

There’s including the laser.

And then there’s including producing the fuel, which is the true unlimited energy milestone.

These experiments are about ignition. It’s producing that much energy in a few billionths of a second.

Once we’ve solved ignition, keeping things going is theoretically much easier.

It took us centuries to get to the Wright brothers and from there 60 years to moon landings.
