Dope Tech Episode 2

<<@veritasium says : Use code VERITASIUM to get 50% off your first monthly KiwiCo Crate! https://www.kiwico.com/VERITASIUM>> <<@Stio942 says : WAX IS MAX>> <<@victorloureiro5004 says : Engineering is the closest humans have gotten to magic!>> <<@JOEMARJAVIER-j6e says : The thing is why are peoples blinded for you to secrets that the types of petroleums is kerosene not a high octanes? That is a art of wars of yours for me that is basic study guide>> <<@waynepitre1641 says : can you make a knife or axe head this way and would it be sharper longer ?>> <<@pawelkruk1404 says : Great video, as always. Thank you Johnny Harris and the team. This all ties up so nicely with how the history of this region was prtrayed in a book called The Prisioners of Geography.>> <<@Mom-t1d5r says : A good content creator would have not posted this video until 6 months or more later with an update added at the end.>> <<@ProbalSeal-j9y says : this is simply for me uri baba>> <<@nuvostef says : Henry is so dang cute! 😁>> <<@prasoon_shukla_ says : One of the best videos I have seen. My way of looking at an airplane has changed completely. Thankyou for this.>> <<@TheWadetube says : Rhenium is heavier than tungsten with a lower melting temperature. They could use the alloy Tantalum Hafnium Carbide and have a much lighter metal with an even higher melting temperature. Also they could quench cool turbine blades in liquid nitrogen to pack the atoms closer and harder together to improve wear and stress. They tested it on drill bits and the quenched bits lasted 50% longer than un-treated bits.>> <<@9678409639 says : Very simple way to save his life is to ask Dharmendra pradhan to resign from his post not the other way around this is enough of your gundagardi>> <<@MidoDiscovery-g5h says : This is one of the best explanations of jet engines I've ever seen. Amazing work! 👏>> <<@ZerglingOne1 says : AKA: How we made metal diamonds.>> <<@MohamedSamyAlRabbani says : Germany built the first jet engine>> <<@ThinkLooped-n3y says : That's very crazy, but it seems like simple concepts>> <<@la.mangosta says : Human: does highly skilled job Derek in front of human: couldn't she be replaced by a robot 😵>> <<@jingizkhan says : these animations and parts presentations are highest quality. hope the 2d and 3d artists get what they deserve! would be at least over 50% of what this video generates.>> <<@akimbojimbo3763 says : 14:03 is that a Audemar??>> <<@Ed.E says : Can’t believe veritasium was in Derby lol>> <<@williamjohnson2247 says : How about doing a video about logarithms.>> <<@AaronSchwarz42 says : There are different grades of titanium, high grade 7000 series Aluminum alloy stronger than Grade 2 titanium, but Grade 5 titanium way better than any aluminum alloy, except in terms of low mass, alloys of lithium and aluminum used in Falcon 9 rocket by SpaceX, have unmatched strength to weight ratio, at very high cost per kg>> <<@AaronSchwarz42 says : Electric ducted fans with brushless motors, carbon fiber complex geometry blade, carbon housing, with very close tolerance between the blade tips and housing, that produce incredibly efficient thrust, able to send RC aircraft to amazing speeds, with lithium polymer battery packs, some aircraft for training with 30min to 1 hour of flight endurance near airports that emit radically less noise and no air pollutants locally, are already a commercial technology, now for passenger aircraft they can use hydrogen fuel cells to make energy, composite tanks for high pressure H2, low mass fuel cells, that power electric ducted fans of aerospace cost and quality that for medium length flights, smaller, few passengers, can work, as can hybrid turbo fans that use both brushless motors and jet fuel engine core, combining them into series hybrid engines>> <<@Napo5000 says : Okay the bubble demonstration was the best I’ve ever seen of yhis>> <<@Corosar says : the fact we learned how to make monocrystaline metal blades for these.. i can't help but be impressed.>> <<@Orenia-ships-byler says : this is my comfort veritasium video>> <<@RobertNagel-s2z says : I aam just a normal dude that works as a maintenance person. I know how to weld a little. This is beyond anything I know about metal. I might have to watch it again.>> <<@AntonioBanderas-c8l says : It is a sad day when "ridiculous" gets you more clicks than "fantastic", "genius", "amazing", etc.>> <<@michealdavis9884 says : Don't lie the natzis had the first everyone raced to steal them>> <<@kennethhammond4028 says : What grade of metal is that....all of it>> <<@adriancacencu says : The first to invent a jet engine was Henri Coanda. But they call it “propeller-less motorjet propulsion system” so that a brit gets the credit and not some Romanian “swine” as the British call us.>> <<@JohnConnor82-m7z says : I’ll be damned…>> <<@alive1691 says : This is probably my favourite Veritsium video of all time.>> <<@DK-lg7ti says : Excellent Engennering info. join today>> <<@rmason9842 says : Great detail! Excellent graphics!! Well done on this video !!>> <<@AvinabMaharjan-r1s says : This is one of the best video i have seen>> <<@KentonVenskus says : Never thought I’d see “Thot” in a math equation before 5:10>> <<@argeebargee1503 says : Totally fascinating!>> <<@ГригорийНазаров-ь2г says : Sorry, you got a typo at 4:04 in the right Kinetic energy formula>> <<@davidolepesa says : Really appreciate the insights in this video.>> <<@jimspringer says : better buy some GE and Rolls Royce stock>> <<@AhmadwalidWalizada says : بهوشت الهیاء215>> <<@geezerp1982 says : now do the ridiculous engineering of PISTON engines>> <<@jawidnikan8892 says : And yet they are not able to rescue the passengers in case of an emergency!?...ridiculous!>> <<@seek3n says : Concept for vibranium something lkke many layer different material and crystals that when counter thermo it react differently and strengthen the outer layer and crystal where get struck send electric that charge some atom cause to strenthen blah blah?>> <<@arthurdmello680 says : Each stage compresses the air by 1.2 times the inlet pressure. How is it possible to compress to 50 atm. With an engine having say 11 to 15 stages? I think the high pressure turbine rotates at much higher than 12500 rpm while take off. Can anyone please clarify>> <<@favourfrederick5553 says : They are literally giving partial info, and clearly hiding some sensitive info so as competitors may not have an easy steal. Good Job though>> <<@krishchauhan-cs3en says : Really flabbergasted by the engineering behind those small yet strong blades. Humans are incredible!>> <<@reset_au says : phenomenal video>> <<@nathanfish9137 says : So let me get this straight... In the 1960s: Gas was 25 cents a gallon A loaf of bread was 10 cents Flights were $300 In 2026: Gas is $4-10 a gallon (sorry California) Bread is $2 a loaf (for store brand) Flights are $379 🤔🤔🤔🤔This mf math ain't mf mathing yall>>
