Dope Tech Episode 2

<<@offgridpete1835 says : Have you noticed that these videos never seem to age well. China is now testing their vacuum high-speed train that can travel over 1,000 km/h. This ultra-fast vacuum tube magnetic levitation system could reduce the travel time between Shanghai and Hangzhou (distance: 200 km) to just 9 minutes. But that’s impossible because the guy who made a career out of telling you why he thinks things are impossible said so. 😂>> <<@BoogieDaCat says : That guy has created a tube going all the way from the inside of his butt, reaching into his lungs.>> <<@thomaslehner5605 says : 9:49 Actually no. The force goes not linearly with the speed but with the square. Therefore 1000 times the density corresponds with about 30 times the speed.>> <<@csnipper524 says : I'm starting to think Elon is sharing his ketamine with these people.>> <<@DanielFresl says : 1.Problem:Divergence (litospheric plates) 2.Problem:Vacuum in inside +high pressure on the outside 3.Problem:Corrosion 4.Problem:Power supply 5.Problem:find an idiot that wants to put his life on a risk>> <<@Zminator1986 says : So these ocean tubes has to be built both like a submarine and a space shuttle at the same time? This is a special level of stupidity.>> <<@JabelldiMarco says : You could have added a clip of a water jet cutting machine to illustrate the force of water under pressure.>> <<@nicholashylton6857 says : Thunderf00t's video was prophetic of the Oceangate Titan tragedy.>> <<@nicholashylton6857 says : I thought about the idea when I was kid. But coincidentally, on that _same day,_ I found out about the mid-Atlantic ridge. I was a little sad my genius idea was DOA. 😢>> <<@mr.lumbergh says : Cool! It can crush not only from differential air pressure, the hyperloop can crush from hydrostatic pressure too!>> <<@georgegonzalez2476 says : There is the not so minor problem of meeting common-carrier requirements. Your basic train, bus, or plane has to have emergency exits that take you to a safe place, outside of the vehicle and to a safe atmosphere. Awfully hard to do that when you're in a capsule, in a vacuum, down miles in the ocean, and down a ways into the rocks. Not gonna be approved. Underwater tunnels like the channel tunnel, they have escape routes, at normal air pressure to a maintenance tunnel. There's also the problem of cost. The channel tunnel cost about $9 billion. The undersea tunnel would be about 100 times as long. Even assuming the same construction costs, that would be easily one trillion dollars. Actually, it's going to take exponentially longer and cost exponentially more as you have to drag out the crushed rock all the way back thousands of miles. There's also the maintenance problem-- it's probably going to need refurbishment every 50 years or so. But the drilling speed is likely to be under 10Km per year, so it would take like 300 years to dig it out once. Meanwhile the existing tunnel would have to be refurbished like six times over.>> <<@alandoren4953 says : >You would have to be insane to go work under the ocean. And where would the workers stay while they work there? Because commuting seems very unlikely? Or will they use Tesla bots to do the job? And so many other questions...>> <<@dirgefanclub says : this aged too well, as usual.>> <<@thorin1045 says : wait a minute, it will smell of strawberries? you sold it to me...>> <<@fredrik3685 says : The obvious solution to the problems of mounting solar panels on the sun is, of course, to do the job during the night. I bet there is a similar solution for the tunnel under the Atlantic.😄 Thanks Thunderf00t. World class>> <<@DrWhom says : Mary Poppins is from Venus!>> <<@RobinMarks1313 says : I was promised flying cars. WHERE'S MY FLYING CAR?>> <<@red_isopat says : putting a vaccuum chamber under like 5km of water, what could go wrong lmao>> <<@thomazmareli says : The transatlantic tunnel was proposed in 1888 by Julio Verne's son. And this exactly "elon musk's project" was presented as a Sci-Fi building by the program Megabuildings S01E03 in 2003.>> <<@mikehill2334 says : I don't think there is anything so stupid that people who believe in an invisible space wizard won't go "yup, sounds legit">> <<@PogodinPavel says : I really don't understand mocking the Concord. They were flying for like 30 years. Isn't that a somewhat success?>> <<@werce9120 says : What if we built a bridge connecting california to hawaii? I think that is a good idea and would not lead to any problems whatsoever :D>> <<@TopTierGaming6900 says : We might even have a concord MK2 in the 2040s and that would nuke this project>> <<@TopTierGaming6900 says : Vacuum tube + external water pressure = even more of a implosion>> <<@TheSmashingDoc1 says : tecktonik shmecktonik, who cares. they laughed about solar roadways and now we drive on them everyday.>> <<@jacklarson6281 says : build a Hyperloop to the Moon>> <<@LD-qj2te says : Always listening to an intelligent rational well researched and delivered response . I am soooo sick of the ever growing flat earther types with their proclamation types of ideas and beliefs or the other side of the spectrum of baby brains who Ake a statement then say why not or how do you know ! It could be or you can’t say for sure>> <<@M_Jono says : You cant blame them , this kind of people are promoting their idea infront of investors and wolf of wallstreet guy . This kind of presentation is not intended for scientist and engineer.>> <<@raven.dracali says : 6th grade geology is just too much for some people to handle Thunderf00t.>> <<@Wintelburst says : Imagine sucking vacuum inside that long ass pipe while the outside pressures are immense, not to mention vibrations... oh boy! Vacuum chamber of that size... and the increased pressure difference of it all... oof! There is ennough nightmares in that idea already.>> <<@harrycooper5231 says : The Concorde was decommissioned after the last crash, which was caused by a piece of runway debris. The changes required by the FAA to ensure this didn't happen again would have been prohibitively expensive.>> <<@ShadowTigerKing says : The idea is crazy for a number of reasons but what the actual funk is Thunderfoot going on about with the massive diving/pressure rant?>> <<@leonardovargas4489 says : First rule of diving. always breathe !>> <<@andythedarkone1982 says : Somebody watched Seaquest DSV and thought it could actually work, they had an episode in season three exploring a similar concept.>> <<@NaziGOPBallmer says : You should see that one Mythbusters episode whete they demonstrated what happens to flesh deep underwater when an old style submersive suit malfunctions.>> <<@barrydheil says : Dyson sphere bridge! Dyson sphere bridge!>> <<@earlgrey2130 says : We need less mobility, not more. I don't wanna be able to get from ny to london in two hours. I wanna wave a future for my kids.>> <<@boathemian7694 says : 1,000 passengers on a Scamship makes far more sense.>> <<@Kiyoone says : Imagine if this guy said that they should put auto driving teslas in that atlantic tunnel😂🤣 This is why you can't skip school and became a science youtuber... But i cant believe that those people get money from YT>> <<@Hooskerdoos says : An underwater vacuum tunnel is right up there with thinking a hot air balloon is the best vehicle for space travel.>> <<@Tjalve70 says : I'm not saying this hyperloop under the Atlantic is a good idea. But IF they were to make anything even similar to it, it would probably go from Scotland to Faeroe Islands, and then to the east part of Iceland. Then it can cross over the midatlantic ridge on Iceland, and continue to Greenland and Canada. That route is also not nearly as deep as the route you were showing. Which means shorter cables, and more stability. I'm still not saying it's feasible. But at least it's a lot more feasible.>> <<@makhoe1 says : 12:55 WTF is that cool bit at the end?>> <<@wesleymays1931 says : Of course Because if your design's biggest problem is maintaining a pressure difference inside a large, long tube, why not increase that pressure difference _even more_ Great idea>> <<@johnbeyer2211 says : Undersea by rail Ninety minutes from New York to Paris Well by seventy-six we'll be A.O.K.>> <<@KilgoreTroutAsf says : Ah yes, a rigid tunnel spanning two different continental plates. What could possibly go wrong?>> <<@papnochetherealone9484 says : Its like those tech reporter havent passed highschool scien heck even in gradeschool some kid could have said that this idea was stupid and explained why>> <<@MartianDanTheMartianMan says : What if we just all started levitating?! What is keeping us to do that? Bias toward Gravity?>> <<@jebise1126 says : i have no idea whats the point of this pressure talk for dummies at start anyway...>> <<@jebise1126 says : does it even need to be busted?>> <<@FizzleFX says : 1:35 Dysonsphere>>
