A giant donut-shaped machine just proved a near-limitless clean power source is possible


There's no silver bullet to the climate crisis, but nuclear fusion may be the closest thing to it. In the quest for a near-limitless, zero-carbon source of reliable power, scientists have generated fusion energy before, but they have struggled for decades to sustain it for very long.

On Wednesday, however, scientists working in the United Kingdom announced that they more than doubled the previous record for generating and sustaining nuclear fusion, which is the same process that allows the sun and stars to shine so brightly.

Nuclear fusion is, as its name suggests, the fusing of two or more atoms into one larger one, a process that unleashes a tremendous amount of energy as heat.


I find stuff like this fascinating.

"crisis"

reply

yes a topic there is over 99% consensus among scientists over, akin to evolution and grvity.

reply

That % is a funny little number that gets thrown around. It changes depending on the wording of the question. Do we have an effect on the climate? Yes. It was a conformation bias trick akin to asking a man of science "If you add .000000001 ibs to 10,000 ilbs, have you effected the weight?" That answer is also yes.

The consequences of this "crisis" seem only to exist in forecasts and computer models. The calamity we see being blamed on "climate change" are indistinguishable from the rampant unpredictability of weather for as long as we have been observing it as well as what we can deduce from evidence. It rose to popularity as the newest way to raise taxes without triggering revolution (like taxes above %50 have historically). Think of how much tax revenue has been collected in the name of "climate change" and that should tell you everything about the science behind its validity. %99 of scientists agree with whom is funding them.

We should be good stewards of the planet and not pollute etc. That noble idea has been honed into a political weapon that seems vulnerable to too much information as it avoids debate.

Interesting, You gotta be in awe of the genius of some people for figuring out things like this

BTW that machine looks like something HG Giger might design

I know, right?

And the name "tokamak" fits perfectly.

reply

This is pretty cool! Hopefully this will replace other forms of energy....

reply

I hope so. I'm tired of folks who resist new forms of energy, including renewables, as too expensive. Most new things are more expensive, at first. But doggonit, we're never going to get anywhere when people immediately reject anything new in this area. For Pete's sake, they're more than willing to embrace the newest iPhone, so....🙄

reply

Yeah, totally agree!

Practical fusion energy has been just around the corner for decades. Don't get your hopes up just yet. A statement from the 70s: "We have commercial fusion reactors in 10 years". It's been 10 years away for 50 years!

reply

From your description I thought it sounded like Tokamak from the 1980s. Reading the article I see that it is. They claim they've improved the process.

i am only interested in an Arc reactor, Fusion is so 2019

reply

I don't trust anything 'nuclear'. I want wind, solar and dams. And we can run everything on batteries.

reply

Yes - but we may have a while to go yet:

The experiments produced 59 megajoules of energy over five seconds (11 megawatts of power).

This is more than double what was achieved in similar tests back in 1997.

It's not a massive energy output - only enough to boil about 60 kettles' worth of water. But the significance is that it validates design choices that have been made for an even bigger fusion reactor now being constructed in France.

So basically this whole experiment was so they could have a mid morning cuppa ☕️

reply

It's the British way - so much so that the kettle is now a standard unit of measurement.

I'm drinking tea as I type.
