The moment UK nuclear fusion reactor set new world record for energy output

In its final experiments before being shut down for good last year, the UK's JET reactor set a world record for the energy output of a fusion reaction

If its so hard how come Tony Stark made one of these in a cave with a box of scraps

I've been hoping for a long time they would try to break all previous records in the final days before shutdown. Looks like a marginal (10 more megajoules) energy production record but not a power output record, and so the Q factor is still lower than the 1997 record of 0.7; while a little disappointing, this is to be somewhat expected since the divertor wall is now made of tungsten instead of carbon, as it was in the 90s, and the radiative bremsstrahlung losses from tungsten ions vaporizing into the bulk of the plasma are hard to overcome even with the upgrades to the ion cyclotron resonance heating and neutral beam injection systems that have taken place over the intervening decades. Still, it is a fitting end to a very productive and scientifically valuable machine.

Imagine these in future could power everything… we’d have enough to open up nearly limitless possibilities in technological advancements.

Research LPP Fusion, it’s the way forward for scalable and reproducible fusion.. it should be funded a lot more.

[akashchopra]

That was enough to power 12000 households

Поздравления !)
Это определённо успех.

[Imthesoulofthes]

Great now make it smaller and stick it in a Suit of Armor

[lindaj]

Umm, didn’t like that sound at the end … 😬

[future_physicist]

when can we use this energy as a source

[Ponas_Lukas]

Once again article never mentioned power input. What a joke

[ratuadilFF]

Mas putin di inggris sudah bangun fusi nuklir, ,

[FrontSideBus]

Stop all research into wind and solar and put it into this!

[ztxokbp]

69 mega joules or in layman terms power for 4-5 baths per BBC. After 40 years of R&D at JET Lab.

ITER originally cost 5B Euros, now delayed and cost quadruple to 20B Euros. Maybe ITER will get it to 10 hot baths after spending 50B Euros

[aranklogu]

Still meagre upgrade...and extremely slow in progress given the amount of money spent on the project. Feels like researchers and administrators are more into funding than the actual result.

[aaaaaa]

This didn't last long, therefore it's still practically useless.
Egely György's cold fusion device is smaller, cheaper and it works.

Without context this is meaningless in practical terms. I'm a complete layperson but I suspect this was spendy and futile, I mean you can demo virtually anything in research conditions. Big fd.
