        It was wild taking my biological sciences ethics class and they said pretty much explicitly that that’s the US’s strategy and that it’s a good thing. And I was like “Hey maybe the profit motive being involved in science research is bad, actually” and most people in the class looked at me like I’d grown 3 heads.

        They also didn’t appreciate when I said “No actually you having a PhD does not make your labor inherently more valuable and in fact a lot of the work would get done without you but none would get done without the people actually doing your experiments.” Academics are such pretentious fucking narcissistic babies I hate them so much

      The US energy sector is a for-profit enterprise and they'll do whatever gets them the most money. They don't build fision power plants because the capital costs are so huge that, by the time it pays itself off, they could've used the profits of an oil-based plant to build another oil based plant, and the CEO in charge when the project started has retired.

      The capital startup costs of a tokomak-style fusion reactor are almost certain to be even higher than those for a fission power plant, so even though it's a great technology, it's still dead in the water under the capitalist system.

      But this is apparently inertial confinement fusion, which everybody said has no chance of getting there first, so I have no fucking clue what the economics of that are.

    Just clarifying that the net gain in energy in this experiment isn't in reference to the actual total amount of energy the facility used to achieve ignition. What they mean is that the fusion reaction produced more energy than the amount of energy the laser imparted onto the fuel. Inefficiencies in producing the laser beam and any energy the laser failed to impart onto the fuel are unaccounted for.

    That said, this experiment isn't meant to account for those inefficiencies because it's not supposed to be a practical reactor design. Rather, it's just a test bed for finding out if it's actually possible to achieve a net gain over the energy imparted onto the fuel, and it looks like it achieved exactly that. So while we're still a ways off from applying it to commercial power generation, it's a very exciting breakthrough nonetheless!

      The only possible issues I could foresee are from mining rare earth materials, which we do already and is already horrendous but less bad than climate change because its still stuck to a local area. Desalination plants might also be in the supply chain for fuel and they arent the best for the environment either, but thats still a local issue especially when considering how little fuel you need to maintain the reaction.

          have we ever really seen all the consequences ahead of time?

          Yup. You can always find someone a century or eight ago who laid this all out in terrifying detail. Some guy made an offhand reference to the greenhouse gas effect in the 1880s, a guy in the 1920s ran the math and said it was going to eventually be a problem, and in the 1970s Exxon did a study, proved it was apocalyptic, and then spent the next fifty years doing everything in their power to cover it up.

          Lead in gasoline? They knew it was toxic the day leaded gasoline was invented, they just couldn't prove how toxic it was. So for like seventy years the lead companies would say "Well its' not that bad" and the researchers would say "it's bad we just can't quanitfy exactly how bad" and the issue would get put off for a few years and by the time it was finally banned we had the Boomers.

          Lots of shit like this. Penicillin resistant bacteria? It's been a thing at least my whole life. Some doctors in my family were describing exactly what ended up happening with Covid decades ago and basically everyone in the medical profession understood that globalization and cheap air travel would eventually result in novel pandemics society would be completely unable to cope with. It was obvious it would happen. The question was when and how bad?

          Communists have been screaming about fascism in the US since 1945, most of us just didn't listen.

          Rubber (rubber blight), Helium (helium is a product of radioactive decay and takes like millions of years to regenerate), a bunch of rare minerals, and a couple of other things all face serious, catastrophic shortages. All rubber trees are clones and one blight disease could wipe out natural rubber production. Helium use goes up but there will never be a new natural source of helium on earth on any human time scale.

          There are so, so, so many foreseeable disasters with apocalyptic outcomes that are simply a matter of "When?"

        Fusion does produce radioactive "waste", not to the degree that fission does and the half life is only like 15 years (tritium). Now, it's not actual waste because tritium is also a fuel source for deutarium-tritium fusion lol. The actual waste product is just helium, there are radioactive isotopes if helium but they all decay very very rapidly. Fusion apparently creates lots of secondary radioactive waste, as in waste produced not by the actual process like fission but somehow by the generation of power - I don't know exactly how but it does get brought up by scientists.

        Deuterium is super common, you can get it here just in the atmosphere. Interestingly, tritium could be relatively abundant on the moon - meaning there could be a commercial reason to do frequent moon visits or even colonize. So, if you like sci fi there you go. Right now they get the tritium from some process involving lithium, so I guess we'll see which capital decides is more profitable. Would be nice to have world socialism and we decide based on which causes the least harm...

          It's my understanding that nuclei in the walls of the reaction chamber absorb many of the high energy neutrons produced by the reaction, transmuting atoms into radioactive isotopes within the previously inert material. This process is called neutron activation: https://en.wikipedia.org/wiki/Neutron_activation

          Even fission doesnt really produce 'waste', its still useful we're just idiots and don't build anything to use it with because we have an addiction for building nuclear missiles. And yeah, the waste from fusion is actually even more useful than what you get from fission.

      Super magical science where if you shoot the right atoms in the right way with a giant laser, you get more energy out of it than you put in. Which means if you put in a fuckton of energy in you can get x amount more out, which is fantastic.

          Yeah it generates heat which goes through a vent to turn a whatever, but thats actually the excess energy produced through heat. A lot of it is absorbed and immediately put back into the grid because the plasma carries an electric current itself and you can just store it back in.

        true but they are all fission catalyzed fusion weapons. the holy grail is pure fusion weapons.

        imagine this: pure fusion weapons would basically create an entirely new type of warfare. something using an advanced conventional explosive to create enough pressure to detonate pressurized fusion fuel without the fission explosion first. no uranium enrichment needed. likely fusion fuel could be made from water and a bit of lithium.

        opens up nuclear weapons to basically every nation with even the smallest national research/engineering capabilities. because the bomb design will get out.

        oh and if they finally crack the design now you have nuclear weapons capable of detonating with any yield you want as well as being built incredibly compact. no fallout only a single neutron burst means they will likely be used frequently since collateral damage is limited to the weapon's blast radius.
