Dope Tech Episode 2

<<@tomcolgan-tl7zk says : So basically, as soon as the reaction produces energy it heats up the magnets and stops the reaction .... Is that right ?>> <<@windigo000 says : c'mon... I need energy for main slumber of the day 😁>> <<@Wildboy0001 says : 600 million tons of hydrogen transfered into energy PER SECOND? Unbeliveable. How?>> <<@driver49 says : I like the meme of a "human creating the most complex machine possible to boil water. Well played!>> <<@steve25782 says : Our fusion reactors won't do it the way the sun does it: They'll use only the easiest fusion fuels deuterium and tritium, and be much hotter than the sun. Tritium will be a valuable resource that never leaves the fusion reactor except in containers so it can be sold. Fusion reactors will breed more tritium from lithium than they consume, and new high-temperature superconductors give powerful magnets that contain the needed incredibly hot plasma without consuming energy themselves, CFS expects significant energy from fusion in about 2 years and fusion power on the grid before 2035. :-)>> <<@MrZevv says : Think abour Elon would have created Fusion and not ähm yeah.. i think the only thnig HE created was this Bullshit Cybertruck .. but think about it.. The world would be a new Sun today :D>> <<@eastvalleycomputer says : Impossible Plasma expansion pressures and temperatures in the suns or(star) gravity are impossible without containment by gravitational forces from immense matter holding the fusion reactor together. Expansive forces of fusion energy require a way to create immense gravity to contain it. Not possible for all human history class periods for a very long time. Matter to matter elemental conversion (fusion)requires immense gravity from immense matter to contain the explosive forces of Fusion Pressure that is held by matter pressure gravities of a star.The Fusion forces are held in place. Sorry this is not an Edison light bulb of dark energy.This is not possible without the blankets of trillions of tons of hydrogen matter above the fusion reaction sun matter capacity. 4 atoms hydrogen make 157 tons of Trinitrotoluene and 600 grams of experimental suicidal hydrogen used for a 25 megaton thermonuclear fusion reaction is an instantaneous hydrogen bomb. Put fridge magnet back up on the reality of the printed paper of gravity and mass in a sun. Can you hold back thermonuclear weapon of expansion energy deep in the sun? People need the help with the education of fusion reactions on the earth's surface without intense mass and gravity. Can a Neutrino answer my question? Yes. Otherwise no Class II 60 sun Iron-56 nutrients in my toasted wheat breakfast cereal. People..find awareness. The key to your mind will open. Try to understand basic reality 101. The narrow focus of intelligence in this period sucks. No human asks any questions. Fast forwarding now! The Combustion Era. Glad it ended so fast. 60 Sun cereal breakfasts. What's in your cereal? Hopefully the reality of truth or sorry I just watched the news. The Digital Dark Ages. Hold together Humanity. Our Prayers are with you. Godspeed!>> <<@hannakukhta4956 says : I like how humanity invents the most complicated and expensive machines to do simple stuff like boiling water>> <<@gregeoryl says : Pretty obvious when the legitimate labs are talking about achieving seconds of fusion, while the propaganda mills claim to have production power plants.>> <<@ralalbatross says : You are about fifteen years out of date man. The reason fusion has languished is because containing highly energetic charged particles and keeping them stable is harder than dumping a big lump of reacting material into a pond and letting it heat said pond. It's not really surprising that since the advent of modern super computers, fusion research has jumped about three orders of magnitude in a decade. We simply know much more about plasmas than we did a decade ago.>> <<@LarsMach says : Disregarding technologies people are surprisingly lacking interest in cost per kilowatt-hour. It's like the "wind does not send an invoice" thing (wind turbine manufacturer does). Even developers' models say that fusion power plants will need giant capacities to get close to competitive level. That makes such technology not very handy for most grids (even more decentralised in their architecture nowadays).>> <<@yuxanne. says : Can u talk about China's fusion project, I wanna hear it from you>> <<@stevelobs6601 says : Fusion for power-supply will never work on earth, because there a simple reason. You need a constant flow of plasma, because if you restart the plasma you will never get put your input. Because the theoretical output doesnt matter. The real output is way lower. Means you start the fusion and the must run constantly. And there is the simple problem. How you get in and out your reactionproducts from the plasma without cooling it? I think it isnt possible, but okay if there is a solution, they can research first this. Until they dream of big machines which cists 100 billions, and the basic problem in my opinion isnt solved.>> <<@SpottedHares says : Well for one we are In fact quite a way off and their has been no know trick In physics to make it easier. We kind of have to do the hard work and that takes a lot of time and money to do. As of the writing of this comment we’re at best 1/6 to 1/4 of the way to the desired temperatures for a proper reactor. Then the biggest reactor ITER is still about 1/10 the size of a desired reactor size. The reality is that this is not a short term project and at best we might start getting viable fusion in the 22nd century.>> <<@hasangarmarudi2178 says : Fusion technology did indeed peak. It was called Tzar bomba>> <<@ron6625 says : We sure could use more thunderfoot videos like this...instead of all the..well. you know.>> <<@MonkeySimius says : It is really interesting view little energy the sun produces power kilogram. But that is largely due to the sun being surprisingly not very dense when you factor in the sun's surface...and most of the energy is produced in the core where it is actuality dense. This got me wondering... In the core where it is densest and producing the most energy... How much energy does the sun produce per kilogram?>> <<@ZenoneLabs says : please get a mike with better gain and pop filter>> <<@friendofvinnie says : Thunder foot is the Bomb 💣>> <<@Ignisan_66 says : The biggest mistake is trying to pursue hot fusion instead of trying to figure out cold fusion. Trying to force nuclei together using heat is extremely inefficient. But cold fusion... If we managed to figure it out, imagine powering your entire house + cars with just your urine. (using deuterium in that urine). It would revolutionise entire power generation.>> <<@tomwende5529 says : Okay, so I'm a year late to the party. I admit that I thought we HAD figured this out, and now I not only know that we DID, but also why only Elon can build it. Next year.>> <<@Chocolate_teapot420 says : Plasma physics is not my area of expertise. But didn’t the Chinese superconducting tokamak achieve 403 seconds of a confined reaction last year? I’m open to being corrected. But can someone explain this?>> <<@honkeykong9563 says : Does Thunderfoot believe that Nuclear Fusion Powerplants will ever become a thing?>> <<@CarlStreet says : The answer is that it is GOLD fusion -- research will continue as long as funding. The goal is NOT and never has been fusion power but financial scam...>> <<@TristanMorrow says : 🚂 iirc as a train nerd, that "glorified hot-water heater" refers specifically to the Worthington™ feedwater heaters on North American steam locomotives -- this Worthington guy got the idea to heat the water from the locomotive's tender before injecting it into the boiler. The details vary but generally exhaust steam from the cylinders is plumbed over to heat it up, indeed a glorified water heater compared to the high pressure boiler. The thermodynamic efficiency of steam locomotives is truly abysmal, so I don't argue with the simplistic sentiment... 🚂>> <<@brianlaney7596 says : Fusion programs are just really expensive day care centers for physicists. However, without them we’d have feral bands of rival physicist gangs roaming our cities spraying equation laced graffiti marking their territories. It would be reminiscent of the dark days of the Knights Who Say Ni…Yes, dark days indeed! 20+ years working at General Atomics around both inertial and magnetic fusion programs has convinced me that we are closer to building a Dyson sphere than a terrestrial fusion reactor.>> <<@raylast3873 says : Remember though, that with Chernobyl the Soviet government at the time went to enormous human and financial efforts to minimize the long-term contamination around Pripyat. We‘re talking things like replacing (probably) dozens of hectares of topsoil, coating everything in sight with a specialized, aerosol-binding compound, and then there‘s the Sarcophagus, which to this day is a massive financial drain for Ukraine. Even if you ignore the human cost, the economic one is still staggering. There‘s a good chance plenty of modern-day countries faced with such an effort would risk bankruptcy. Which is bad, because that means it wouldn‘t be done correctly, everyone would be cutting corners, etc. And that‘s ignoring the fact that if something similar happened in Western Europe or the North American Coasts, even just the one-time local evacuation would be a human and economic catastrophe, even if the radiation itself killed exactly zero people. A mere 30 km exclusion zone in these parts can easily mean removing millions of people and shutting down economic activity the equivalent to, say, Belgium. Heck, a nuclear accident in the wrong place could absolutely kill the economy of Belgium, literally. And I think there‘s one big elephant in the room you‘re ignoring here: yes, meltdowns are relatively „minor“ catastrophes with consequences that can be reasonably calculated. However, that‘s only true as long as the corium is completely contained and never makes it into the ground water. If that ever happens, things can potentially get extremely ugly.>> <<@spianny says : ❤️>> <<@haruhisuzumiya6 says : France has an experimental reactor for fusion usa has an neutron gun that turns metal into spaghetti>> <<@haruhisuzumiya6 says : Cold fission, liquid nitrogen and plutonium rods 😎❄️🔥💥>> <<@gabrielclark1425 says : Personally, after nearly a century of experiments trying and failing to use the theory, I feel that the scientific community needs to entertain the possibility that the idea of the sun and stars being fueled purely by nuclear fusion is wrong. While we know that nuclear fusion is occuring there based off neutrinos, all experiments we've done since have definitively proven that it it's an energy sink 100% of the time. At worst, it's as was previously theorized with all being sourced from Gravity Contraction, just with the caveat that energy can be stored by cycling between fission and fusion. At best, it's something entirely unknown.>> <<@davidchavez81 says : IOW, Helion is as scammy as they seem.>> <<@robynsnest8668 says : Hypersun. Callnit hyperson>> <<@Mike_B-137 says : You are welcome>> <<@pauljmeyer1 says : The Sisyphus project.>> <<@PacoOtis says : Dude! We are followers and have to tell you this discombobulated video is terrible! Try to be sober when you do you next one!! LOL Best of luck!>> <<@theultimatereductionist7592 says : @TMmodify What hurt fission the most was the relentless arrogance of pro-fissionists to never ever ever address or take seriously the nuclear waste problem, or prove that all those evacuations after Chernobyl and Fukushima were NOT necessary, were overkill. If pro-fissionists want taxpayer to foot the bill for massively expensive fission reactor Yes, we do need to continue to work hard on fusion, while simultaneously 1. stop people having kids to reduce world overpopulation 2. massively reduce car centrism by tearing up stroads and replacing them with as much public train and safe separate bicycle infrastructure as possible 3. massively increase solar & wind power I'm not for ruling out fission power altogether. But I have encountered FAR too many arrogant comments from pro-fissionists who will NEVER ADDRESS the negatives of fission. They WILL NEVER EVER EVEN ADMIT THEY EXIST. Even I know the negatives of antinatalism, even though I am a hardcore Antinatalist, and the negatives of public transportation, and the negatives of solar and wind (problem of scalability)>> <<@alphaomega4968 says : Bro you are like Adam ruins everything on STEROIDS>> <<@Xan-ax-te2qo says : Okay NO 20:14 always you using a dumb video is using criticize an idiot>> <<@Mescherje says : While talking about the temperature, you forgot about the energy density. I guess it was intentional, because if you explained it, your argument would be lost. So to prove your point, you skip this point and talk about gasilions of Kelvins to make people think that the whole thing is impossible. Well, so far, no one talks about the net energy gain in current or next-gen reactors for commercial energy production. This goal is like a 70-100 years from now. ITER, when it's finally built, will only be a step forward, but it's still going to be experimental and maybe in 2 steps further we get something commercialy useful. Now anyone can ask if it's even worth it. Well, the money seems to be huge, but compared to another things we put them in it's actually not. And the theoretical calculations and engineering knowledge are solid enough to think it's well worth it. That's why the whole world tries to do it.>> <<@AS-tx9zh says : Thanks!>> <<@panjak323 says : Oh boy, everybody wants fusion, when fission can do almost everything at fraction of the price NOW.>> <<@panjak323 says : The Sun is near perfect black body. Ie it's absorption coefficient is almost 1, thus it's great both at absorbing and radiating light.>> <<@thefleecer3673 says : Thanks for this. The scare mongering around fission continues to this day, but if we want to aspire to a future world like Star Trek this is what we need to advance. By the time we create controlled fusion wecwill prbably already have an interstellar civilisation.>> <<@philspidermn says : I am just an engineer, can you help me understand how tritium is calculated to be a billion times more radioactive than uranium and more harmful. Google is claiming it is a weak beta producer and not very harmful to humans. Honest question, and please not the answer be that it’s a fiddle of the numbers to make it sound more dangerous.>> <<@sayharris1361 says : Thank you>> <<@6teeth318-w5k says : I like ThunderfEEt>> <<@nathanaeldean6301 says : You forgot about the nuclear breakthrough by two Japanese Gods beneath a remote Japanese valley. Sadly, I think they ran a problem with safety, so the local shrine maiden of paradise and ordinary magician has to shut it down.>> <<@SkepTank0404 says : @15:30 or so, well... cancer rates have increased quite a bit over the last fifty odd years... well in the period commercial plane travel began increasing, so... 30x background radiation could very well be dangerous, huh?>> <<@TuongNgu-k4g says : Love your videos Thunderf00t! Wish to hear your opinion about SMR.>>
