US scientists achieve ‘holy grail’ nuclear fusion reaction

quote [ The test involved bombarding a pellet of hydrogen plasma with the world’s largest laser to trigger a nuclear fusion reaction, the same process which takes place in the sun.

Researchers were able to produce 2.5 megajoules of energy, 120 per cent of the 2.1 megajoules used to power the experiment. ]

Here We Go! Supposedly, official announcement coming Tuesday

This will totally be used to free humanity from the shackles of energy scarcity and not at all be used as a cudgel to continue bringing the world to heel under the status quo of capitalism!👍😁🎉🎉🎉🎉

Yeah, maybe. Scarcity is a big deal. The technical threshold isn't that high.

I wonder if they were able to harness Updog.

I'm a nuclear engineer and I've never heard of that. What's Updog?

apparently nuclear fusion is what's up, dog.

Not much. What's up with you?

So instead of perpetually being 20 years away from fusion power plants, we'll now perpetually be 15 years away from fusion power plants.

Pretty much. The energy going into the actual fusion reaction is less than the energy that came out by ~20%, but the lasers that put that energy into it are something like 1% efficient and you would lose more converting that heat and radiation into electricity.

Also the current technology can't handle the repeated use necessary for actual power generation.

It's an important milestone for science, but nowhere near being a power source yet.

Q>1 ... Q greater than one, sounds a little like QAnon - amiright??

But can it run Doom?
