I know the cognitive dissonance is a bit heavy for some people on this topic but we already have fusion. Safire plasma can run for days uninterrupted on less than 300 watts of continuous input. https://rumble.com/vbtfff-safire-project-update-2017-and-201...

This is crackpottery, right? All the links on that page point to other theories “debunking” general relativity and some “Electric Universe” fanfic.

Rumble is a haven for crackpots and frauds…not surprising.

It would be kind of cool if by accident scientists can create some wormhole. We can dump all our trash through it into Saturn or something.

Totally, or something like infinite probability drive from Hitchhiker's that would just send our trash to random other universes and timelines. Which makes me wonder, are other universes and timelines sending us stuff? Is that where platypus' come from? P.S. I'm not trying to say platypus' are trash, just that the don't fit in with our indigenous fauna and maybe another timeline thought they were and sent them to us.

isn't this the idea for The Witcher?

Wrong.

The "other links" have fuck all to do with the plasma chamber. This method for sustained plasma had already been around for about two years, with earlier experiments going back to year 2010.

The raw video of the lit plasma is raw video, not CGI.

Teams at LLNL were involved.

My understanding is that the NIF was primarily to explore weapons research in the guise of fusion research. We could use some nuclear miracles to help out with decarbonizing and it seems like we'd be better served investing in something that could possibly become viable (especially with the recent superconductor news).

It's purpose is physics research, which benefits both weapons and fusion for power production, and other fields besides. Being able to study a burning plasma in a lab environment, allowing us to validate our computer models, is valuable even the power reactors we build using those models wind up looking very different.

Ah nice, then they'd be easy to build without detection, and proliferation treaties become unenforceable. What could go wrong? I think my mind just changed on whether fusion energy breakthroughs would end up as a net good.

Non proliferation treaties simply mean existing nuclear states can’t share with others. They do exactly nothing, except apply a stigma/some worthless sanctions, in the event a state decides to fucking do it themselves. See: North Korea.

The Non-Proliferation Treaty actually does bar non-weapons state signatories from developing nuclear weapons themselves, and requires them to accept IAEA safeguards to ensure they are not doing so. The issue with North Korea is that they withdrew from the NPT, then re-entered it, then when they tried to withdraw again they did not give the 3 months notice required by the treaty. They claim that their re-entry into the treaty was merely a delay in their withdrawal, and thus they didn't need to give notice again. The rest of the world disagrees, and holds they are in violation of the treaty, and has sanctioned them accordingly. Sanctions are generally the worst punishment that violating a treaty can result in, barring the few exceptions where war would be both justified and practical.

What's the weapons angle for sustained fusion research? We've had the tech to reliably turn heavy water into 100 million casualties per warhead for >50 years.

> 100 million casualties per warhead for >50 years.

How did you reach 100M?

The blast radius is huge, but not that huge.

Some of the implications, as far as I know: 1- A pure fusion weapon would be a "clean bomb", meaning it wouldn't emit long term radiation. Good, but bad because someone might be more willing to use it. 2- A pure fusion weapon wouldn't require a critical mass. In theory, the laws of physics don't preclude something that is really compact. 3- A pure fusion weapon would use deuterium, which is just a byproduct of heavy…

point 1 is sadly wrong and I wish people would stop thinking that fusion doesn't cause radiation damage in all surrounding material.

I think OP meant "radioactive fallout" which would be the source of "long term radiation." Fission bombs scatter radioactive dust of uranium, plutonium, and fission byproducts that continue to emit harmful radiation for thousands of years.

A fusion bomb with no fission stage would have a massive radiation blast, but leave no radioactive fallout. 10 minutes after the bomb, radiation levels would be more or less back to background levels. Is my understanding.

Smart people like that would do dumb things. Why not park the other end of the wormhole in the core of the sun for dumping trash. Test it first? Nah, surely this thing is one way of course.

Such as... Gleen Greenwald? Also, Safire plasma can't really be disproven.

I have personally seen one of these chambers and that they do run continuously for several hours.

> some people on Rumble I don't agree with so this raw video proof of a sustained fusion reaction is fake.

You are very very stupid. You do not belong on HN. Go back to 9gag.
