Dope Tech Episode 2

<<@zollicb3 says : Just Breeding fear.>> <<@englishcitystone1663 says : A scream of defiance against weaponized stupidly! I feel for you.>> <<@4zul4_iwnl says : i knew this already, but im always facinated by ur capability of explaining stuff in a understandable but intruiging way, while still getting the point along. ill show it to my gf tonight lol, , lets see what happens>> <<@vegasmade777 says : Precious tritium>> <<@Jakeurb8ty82 says : ah the good ol' K-T Plastic Boundary.>> <<@roflmatol says : * These claims of toxicity/radioactivity are poorly researched or presented in bad faith. The advantage of fusion over fission is not a lack of radioactivity in the fuel itself, but how comparatively little long-lived nuclear waste it generates. It's still going to be a nuclear reactor and will still need proper radiological controls, shielding, containment building, etc. * Yes, tritium is outrageously expensive now but that's not really going to be the case if and when there is demand for it. Some reactors being tested include tritium breeding processes as well. When fission got started uranium was even more expensive than tritium is now. * The 4x more energy claim is obviously considering energy generated per unit of mass. D+T fusion: 17.6/5 = 3.52, U-235 fission: 200/235 = 0.85>> <<@WR3ND says : Nice. I have some. Let's see if it devalues faster than inflation.>> <<@proudzerzurancitizen says : japanese sea water>> <<@JohnTorres1987 says : No wonder Dr. Octopus was robbing that bank in Spider-Man 2. It was really expensive.>> <<@labrat9831 says : Hyperbole much? Tritium is radioactive but its a weak beta source. The radioactivity is blocked by your skin or 6mm of air. Safety protocols are literally just a pair of gloves. It's really only dangerous to your health if you drink it or inject it in concentrated quantities which are very hard to come by. Hence why it is sold in vials on the internet unregulated for people to hang on their keychains. You fairly compare tritium to polonium by mass to make a point and then completely abandon that type of comparison when contrasting fission energy from deuterium tritium vs U-235 fission. Mass for Mass, fission does produce 4x more energy (800Mev to 200Mev) since the mass of deuterium + tritium is about 45x less. Additionally on a per mass of the entire fuel, the difference is even greater since in traditional fission fuel the U-235 is only 3-5% of the total uranium fuel composition. You also overhype the cost of tritium but never discuss the fact that it's only expensive because there is not real market for it and thus the only viable source is from CANDU nuclear power plants. You completely ignore the fact that the physics behind making tritium from lithium and beryllium is well understood and generates not only tritium for fuel but also valuable helium. In fact, most proposed fusion technologies incorporate a breeder blanket for breeding tritium. There are significant engineering issues to overcome with this but you never touch on that at all. It’s odd that you preach not overreacting about tritiated water from Fukushima being released and then absolutely freak out about tritium in this video. We get it, you don't think the many difficult barriers to fusion will be overcome and we already have a safe and viable path for fission but this video falls just as flat as the videos that overhype fusion. There are plenty of legitimate roadblocks to fusion but this video doesn't describe one of those.>> <<@patrickday4206 says : Helium 3 is what will have to be used if it will ever be commercialized detrium is just to advance the technology>> <<@jsunnj76 says : cool Video I am a student I can't wait to see the rest of your content...I am excitd to learn more Thanks>> <<@ivanlusenko4674 says : Really? He called him a journalist and showed Wikipedia article about him that says he's a KGB officer? Well done Thanderfoot, you're the Man (Tha Man full of sh....)!>> <<@ArtemSayapov says : I mean fusion is possible, just not in this century probably. We should focus on improving the sources of power that currently work.>> <<@MikElectric_CZ says : Thank you man, as always! If you are ever fancy in beer in Prague, let me know ;-)>> <<@Rehteal says : I don't see what the big deal is. Just go shoot some rocks in space, and boom. Tritium. Or you can go to the Outlaw stations, they always have plenty of it for whatever reason. Way less hassle than having to mine it yourself.>> <<@SimonMester says : I feel like fusion will only be a practical reality when we learn how to cheat/manipulate gravity. That is to say it might just be a little while off. I feel like this whole "use tons of energy on crazy lasers and even crazier supermagnets" is just a bit impractical.>> <<@EleanorPeterson says : A little stronger compression on the audio would be helpful, old bean. If I turn up the volume so that I can hear the quiet, mumbled, whispered parts, the rest is wildly OTT. If I had a cat, it would be clinging to the ceiling and giving me dirty looks. 😾👀>> <<@kevinharte3636 says : So does this mean we should use more thorium?>> <<@adairjanney7109 says : Lattice confined fusion is the only thing that ever worked, even after we completed the first commericial LCF reactor it was so expensive that it was intended only to be used in the first and probably only arc ship. A 2 mile long mega ship being constructed in orbit, never completed.>> <<@No_chama_1 says : 2:25 T2O is actually used as a tracer on water transport studies, so there's definitely a chance someone has tasted it. Even diluted with regular water, the fraction of T2O would definitely affect the taste.>> <<@Darryl_Frost says : There is also the inefficiency of using a very small amount of very high temperature to make a large amount of lower temperature stuff (steam), in order to actually generate useful power. But as long as those research grants are coming in who cares right, it's not like that money could be used for something useful.>> <<@user-pr6ed3ri2k says : Tritium isnt this just weird hydrogen gas>> <<@aleksandarrudic3694 says : The only so far successful experimental application of fusion power (speaking of course of thermonuclear weapons) uses lithium deuteride as a fusion fuel (of should I more accurately say, feedstock). All tritium required for the fusion reaction is produced by fission of lithium due to the flux of excess relativistic neutrons from the fission primary and the "sparkplug" stages - there is no need to have any amount of tritium in the fuel initially. Every half-reasonable fusion design that I've seen, including those that are obviously impractical for continuous operation and large scale power production, are trying to generate tritium on-site. So, the tritium issue is practically nonexistent. What's troubling most serious fusion developments currently is the inability to control plasma and keep it contained long enough for the sustained fusion reaction, but the field of plasma research is in its infancy so there is a lot of potential for improvements. By the way, I'm far from a fusion-power enthusiast, but I strongly support research and investments (investments into serious science, just to be clear, not into those startups that are rebranding perpetuum mobile machines) even if they don't give us a miniature sun in 10 years that's going to solve all of our energy needs forever for free absolutely clean and safe. The science is not about making miracles - it's about knowing more.>> <<@Civsuccess2 says : You can drink 1000x Gold by drinking the water released by Fukushima Daichi for FREE! 😂>> <<@EpicOfChillgamesh says : Bite-sized oversimplifications are so popular that hardly anyone takes the time to start from the beginning and lay out all the information in a logical manner. Thank you for being one of the few who do!>> <<@Guntank says : Thank you sir for explaining it thoroughly --- one of the things schools USED to always enforce is that when you do math or science problems, you ALWAYS show your work. Because if you only condensed it to 30 seconds there'll always be someone who has no knowledge of simple science will come out and just say 'Boiled down it's really just a ___________________, I swear...I swear it's not that hard!' and then get fully funded for another five years of doing nothing.>> <<@steveford1070 says : Got some on a keyring>> <<@iankrasnow5383 says : There would be a few reasons that you underestimated the lethal dose of tritium. Firstly, even though it has 1/290th the energy per decay as polonium, it would cause far less than 1/290th as many ionization events. For the same reason why you can withstand many orders of magnitude more visible light photons on your skin. Or even a decent amount of UV light without causing cancer. The other major thing is that polonium concentrates in the liver and spleen, concentrating it mostly in a small area, and also not easily excreted. Tritium in the form of super heavy water is more dilute throughout the body, and is mostly excreted like normal water within a few days, although a few of the tritium atoms could bind to organic molecules within cells, which is obviously bad. One thing worth pointing out is the mouse studies that they used to extrapolate the LD50 of tritium actually injected tritiated water directly into their blood streams, or had them breathe it. If you drank it, I suspect the toxicity would be lower.>> <<@noneofyourbusiness4133 says : So will fusion ever be usable or is it fundamentally uneconomical forever?>> <<@midwestdevopunk8848 says : All my weapon sights are tritium lol>> <<@nothereforit.605 says : 4:50 not me, im built different>> <<@ilyasabi8920 says : We just need to exploit physics. We need a hack to circumvent the first rule of thermodynamics that's for sure. Otherwise we need to keep more and more energy dense things to destroy so we can convert their potential to kinetic forms of energy.>> <<@bik3r230 says : I work in titriated air all day every day and have no adverse affects? Why would that be when its so dangerous>> <<@bobsponge1877 says : I swear, Matt Ferrell is a joke on Youtube. He does zero research for his videos.>> <<@scifrygaming says : Fusion and the hydrogen economy will somehow save us all ... so they say ... somehow ... not sure how tho ... it all seems so crazy expensive?? lmao Good vid>> <<@blueninety says : A genuine question, why is the decay of an atom measured in a HALF life instead of its full life or even 1/3 life?>> <<@brianlink391 says : Why cant I read the transcript>> <<@Kibernautas says : You should have stuck to Venomfangx types. Now you are just pathetic.>> <<@Echiewel says : The last part appears to be them just talking about different things. Uranium releases more energy per particle (or per mole), but less per gram (or mL at room temperature, or whatever). Because uranium has about 80 times as much mass per particle.>> <<@oscaryuen311 says : I always wonder if fusion can just act like a battery where if we produce (EXCESS) power from green energy then we can use to make fusion but this is just in theory and was wondering what is your take on it.>> <<@SevenDeMagnus says : Cool, we can turn things ON forever: loud speakers blasting all day, car joyride, TV on all day, phones on videos and 3D games all day, there will lots of noise and light pollution though and will burn out a lot of car tires and gadgets faster as well but we can't bake our cake and eat it too. God bless.>> <<@headybrew says : Thank you.>> <<@imperatornicolae3232 says : Question would using waste fuel to generate constant but lower levers of power not be a better use for waste the just digging a hope and dropping it in?>> <<@doyouwanttogivemelekiss3097 says : why this focus on tritium, when a large part of fusion research went into r&d of lithium breeders?>> <<@bijonn says : One thing I'll like to mention that tritium is naturally produced in CANDU-reactors, which previously was a waste biproduct, but is now being isolated and sold to third parties. Of course, I'm not sure if the quantities produced are sufficient for mass-scale fusion production, which I highly doubt will ever become economically feasible in the near-future. Why have fusion when we already have fission, which is way easier to do.>> <<@kylewilson6425 says : Thank you, Thunderf00t! By the way, I have a vial of tritium gas. It has a phosphor that glows green on the inside of the vial. The β- radiation is too weak (18.6 keV max) to penetrate the glass or be detected by a Geiger-Müller counter, however some weak X-rays (Bremsstrahlung X-rays) can be detected from the β- particles slowing down from the atoms that make up the glass. Tritium also doesn't release gamma rays or internal conversion X-rays when it decays either. It's an interesting radionuclide!>> <<@dronexfun8469 says : One million subs, woo hoo! Congrats man.>> <<@spectralcodec says : Well that's a bummer.>> <<@thomasbecker9676 says : Phil, I think you're out of your element here. I'd suggest contacting ITER to answer some of your questions and skewed assumptions.>>
