re: China now holds Nuclear Fusion record - 1000 seconds

Don’t believe anything China says.

They’re pretty honest when they etched the “made in China” on their products and we buy it up like it’s no tomorrow. China had gotten so big that I dont think they give a shite if anyone believes it or not.

Because we all know China is deeply concerned about clean energy.

I think they just want the energy period. Clean I’m sure is just a small bonus.

Assuming you believe them

How many nuclear-powered submarines and aircraft carriers do they have?

Explain it to me like I’m an idiot.

There is A LOT of energy between protons and neutrons. We traditionally release and control that energy through fission at nuclear power plants. The problem with fission it releases a lot of harmful radiation that is dangerous to biological life. So that is the challenge. The byproducts are different elements and a lot of radio active waste.

The opposite of fission is fusion. Fusion is how our sun produces energy. The sun takes two protons, usually called hydrogen, and fuses them together through tremendous temperature and gravity to make helium. Energy is released in that process as the entire electromagnetic spectrum which a very small percentage is visible light.

This Chinese firm is trying to create a micro sun. A small fusion reactor. I have not read the article but I highly suspect they are using focused lasers on some type of hydrogen encapsulation to turn hydrogen into helium and as long as the energy emitted exceeds the energy consumed, we have a power plant. The beauty of fusion is there is no radioactive waste products.

Not clean energy but a limitless supply of energy is the goal here whomever perfects this process first will have the inside lane for establishing themselves as a superpower in the world.

There's no secret how to accomplish this. Once one country achieves it, others will quickly follow. If anything,, it will eliminate the source of most of the conflict in the world. With unlimited energy there's no more scarcity of any kind of resource or material..

I wonder what man-made device can hold something at those temperatures without melting? May be time to utilize the Google machine some.

Magnetic containment of the plasma. There can still be degradation of the walls of the unit. That has been one of the most difficult challenges.

TOKAMAK is a Russian acronym for "toroidal chamber with magnetic coils".
Those have been around since the 50s.

Wonder what they really want to do with it...

Pure Nuclear Fusion is not something that can be weaponized easily, if at all. We already have fission-fusion bombs, where fission creates enough pressure to create a fusion explosion. Pure fusion without a fission explosion to create the pressure is not really a possibility, at least with enough yield to justify the complexity and weight.

Fusion is really the hopeful next step to clean energy. Magnets are used to compress atoms together. Hydrogen isotopes are the preferred and produce Helium and release energy (heat). Helium 3 though is what they want, which is very non-existent on Earth, but believed to be abundant on the Moon.

And every one of them using outdated technology compared to the US's oldest active-service models. We have well over 100 nuclear subs.

China lies about every "technological advancement" they make. They lie about chip manufacturing, EV's, high-speed trains, critical infrastructure, military technology/capabilities, etc. All propaganda, all the time.

If it ever works, it'd be by far the best combination of clean and efficient energy we could have

Which means we will never see it in the U.S. as the fossil fuel industry will claim it is unsafe and will destroy all life as we know it.

This is where we should be spending billions of govt dollars on research

Indeed. Its the most sustainable solution.
