Dope Tech Episode 2

<<@bencrawshaw1227 says : The sheer amount of energy that would be required just for one journey would be ridiculous.>> <<@TheLastOilMan says : We can’t do this in an 7 inch casing at 2 km ! With vamp threaders on the casing !>> <<@TheLastOilMan says : The yanks fall for anything !>> <<@TheLastOilMan says : Musk and Branson haha kindergarten boys,>> <<@spacejihadist69420 says : I'm surprised this wasn't called the Cyberhumantrain because those Elon fanboys had their head on each other's ass.>> <<@JDesq says : Well , well , well, this aged really well didn't it ! Don't forget to invest in Musk's space data warehouses he's building next , just ignore the tiny details on smelting in poor gravity that needs gravity to separate & recover ANY metals to make them usable is imposable though! 👏🤣>> <<@bipolarminddroppings says : Its fun coming back many years later and seeing how much Phil got right. Weirdly, the one place on Earth you would want to put this kind of thing, the UK due to the fact there is no extreme weather or geology, was never considered as a candidate for a hyperloop...>> <<@Larimarc says : BTW Holmes still owns over 50% … of nothing!>> <<@user-plan16 says : you may, just may , have been almighty righty on this one !!!🤣>> <<@kennyfordham6208 says : August 2025 here....I'm still waiting. 😮‍💨>> <<@brennencox516 says : 3:30 Yeah, that's why HSR is great. If maglev in a vacuum (hyperloop) worked, it could be better, but HSR is more economical. And why did Musk push Hyperloop? To kill HSR in California.>> <<@charlessax4385 says : Are these actual reporters? They must be paid shills. Why else would they speaking of promised non existent technologies as if they were up and running?>> <<@profishinjr4880 says : It’s bot>> <<@6teeth says : Why are there led lights in a hyperloop? How do they get powered? Are there windows in a Hyperloop when all you can see is a tunnel??>> <<@MrCalindor says : I would have looooved to see them try to open the door fast, realize it's stupidly hard, use some massive hidraulic system or smth and then 1 sec later see the bottom of the tube on the other side fly off in the sunset😂😂😂>> <<@jimgraham6722 says : I have ridden the Chinese maglev at 420kmh so know it can be made to work. Whether it's any more practical than wheels on rail at 300kmh, I have serious doubts. As for Hyperloop - nope.>> <<@kenday7942 says : My imagination is close to the speed of light faster than Elon Musk’s average project completion time!>> <<@kenday7942 says : The problem with Elon Musk is that HE actually thinks that he’s a genius. He would make a good science fiction-themed comic book author.>> <<@Webicker1 says : Elon Musk's Hyperloop concept, promising speeds of 700 MPH, faces skepticism due to practical challenges. Critics argue that maintaining a vacuum for such a system is complex and costly. Despite its theoretical advantages over high-speed trains and planes, the Hyperloop's feasibility remains uncertain, with many believing it may never materialize. Highlights: 00:24 The hyperloop is considered the future of high-speed transportation, claiming to be significantly faster than both Japan's shinkansen trains and Boeing 747 aircraft. Despite its promise, there are challenges in making this technology viable and operational. -Hyperloop technology is projected to reach speeds three and a half times faster than Japan's shinkansen trains, making it a revolutionary transport solution.

Successful high-speed trials are necessary to garner support for future projects. 06:01 The Virgin Hyperloop is facing significant challenges in its construction and regulatory approval process, questioning its feasibility and the promised speeds. Despite ambitious plans, the project may not meet its goals due to infrastructure limitations and safety regulations. -Virgin Hyperloop plans to build a 10-kilometer test track in West Virginia, but the actual speed capabilities are questionable given the constraints of this short distance. The proposed track cannot support speeds of 600 mph with passenger safety in mind. -The need for a straight track is critical for achieving high speeds in hyperloop travel, which complicates construction in regions with mountainous terrain. The proposed test track is only half the required length for proper acceleration and deceleration. -The comparison to high-speed trains highlights that the hyperloop may not significantly outperform existing transportation methods, raising doubts about its innovative claims. Moreover, past projects like Theranos serve as cautionary tales of ambitious technology ventures failing to deliver. 12:07 Criticism of the Hyperloop project highlights significant flaws in its design and feasibility. The discussion centers on the scientific inaccuracies and unsubstantiated claims made by its proponents. -The Hyperloop's reliance on a cooling system raises questions about its practicality and engineering challenges. The need to store steam in a pod complicates the design significantly. -Critics argue that supporters of Elon Musk's projects often resort to trolling instead of addressing valid criticisms. This behavior undermines constructive discussions on technological advancements. -The video also addresses common misunderstandings about the feasibility of building extensive vacuum systems. Assertions about material availability are often misrepresented by critics. 18:11 Understanding the complexities of maintaining a vacuum in a hyperloop is crucial. The challenges of achieving and sustaining low pressure levels are vital for the system's functionality and safety. -The humor in misconceptions about scientific concepts highlights how people can misunderstand complex ideas. This often leads to confusion and strong commitments to incorrect beliefs. -Maintaining a medium vacuum in the hyperloop depends on strategic placement of vacuum pumps. Properly maintaining this pressure is essential for the safety and efficiency of the transportation system. -The dynamics of air molecules in a vacuum illustrate the challenges of oxygen availability at low pressures. Understanding molecular behavior is crucial for ensuring passenger safety in the hyperloop. 24:15 The discussion revolves around the challenges of maintaining a vacuum in the hyperloop system. Achieving and sustaining low pressure is complex, requiring efficient pumping and sealing mechanisms. -The effectiveness of the pumping system is crucial for maintaining the desired vacuum levels. A properly sealed environment can greatly enhance the efficiency of air removal. -The size of the holes in the hyperloop's structure impacts the vacuum's sustainability. Even small leaks can significantly hinder the ability to achieve optimal pressure. -Different vacuum levels require varying levels of technology and resources. Achieving a medium vacuum is more feasible than reaching extremely low pressures in the hyperloop. 30:18 Understanding how vacuum systems operate is crucial, especially in applications like hyperloop technology. Even small leaks can significantly affect pressure maintenance within such systems. -The importance of maintaining vacuum levels is highlighted, as even minor pinhole leaks can disrupt the entire system's efficiency and functionality. This is critical for hyperloop safety. -The practical demonstration of a vacuum system showcases how pressure changes occur when seals are broken, emphasizing the need for effective sealing in high-tech applications. -Using a microscope to illustrate the size of a pinhole leak provides a visual perspective on how tiny imperfections can lead to significant vacuum loss in sensitive systems. 36:21 The video discusses the challenges of maintaining a vacuum in large systems like the hyperloop, emphasizing the difficulty in achieving and preserving a perfect vacuum. It highlights how any imperfections can significantly impact the vacuum quality, leading to potential failures. -The speaker explains how reducing the hole size in a vacuum system can drastically improve vacuum quality, demonstrating the sensitivity of vacuum systems to minor changes. -A discussion on the construction of hyperloop tubes highlights the complexity of welding segments together, which introduces potential risks for vacuum integrity over time. -The video emphasizes the importance of sealing techniques, such as O-rings, for maintaining vacuum conditions and discusses their role in ensuring structural integrity.>> <<@JMarie-c7v says : These two people are are PR- The old farts 💨 they get to give them money 💰 are suckered into this stuff!>> <<@robertplatt1693 says : Thunderf00t doesn't have minions. He has cupbearers.>> <<@Exkhaniber says : 10:15 Just wanted to drop in here and say that this aged like a fine wine! Who knew that having a working understanding of the real world would allow someone to make meaningful predictions like that?>> <<@dessertstorm7476 says : hyperloop, more like hype loop mirite ppl>> <<@mustangthings says : 7:45 The way he echoes back the noises she makes is hilarious. He wants to hit that so bad.>> <<@hunterhenryk says : This video was recommended to me 3 years later. The hyperloop idea is now dead.>> <<@Atmost11 says : Put your 500k custom cyber beast in pod mode and ignore the haters! Elon! Elon! Elon! Elon!>> <<@youtubegarbage7876 says : I like how the Munich couple films in the Aliexpress sample room.>> <<@johnmcnulty4425 says : Professor Thunderfoot only overestimated the time of collapse!>> <<@johnmcnulty4425 says : I rode the Shinkansen in Japan many times when I lived over there. It seemed plenty fast enough to me. Why are people in such a rush?>> <<@dongtan_bulgom says : love how you say "waxan">> <<@jeremyedowd says : And if a capsule (with passengers) came unsealed inside the low atmosphere tube, their fluids would boil instantly in the vacuum, creating a fast and gruesome death. Last time I took a train the conductor opened a vestibule window to let in fresh air. . . No fatalities.>> <<@palbi says : LMAO they think your fans are doxxing them when it's just viewers from youtube disliking their videos hahaha>> <<@juggernaut316 says : bankrupt>> <<@csnipper524 says : Maybe someone needs to explain the difference between computer simulation and reality. You can make fire burn upside down or reverse gravity in a simulation, but try it in real life. Same applies to this. Maybe they watched the Matrix movies to many times.>> <<@csnipper524 says : Proving the stupidity of something with basic science isn't making fun of it, it's simply a reality check in the vast world of fantasy BS.>> <<@Sapioso says : Thunderfckd. You broke these people lmfao.>> <<@vjollila96 says : Well it didn't even take 4 year for vigin hyperloop to go under>> <<@daviddavis6876 says : And what if someone sabotaged it. How long will it be off line as they replace the defective sections?>> <<@DefenestratedOligarch says : Let’s just do electric trains on the surface of the ground, instead of this idiocy about doing it in a pressurized tube.>> <<@6teeth318-w5k says : 20:00 Gradually increasing wind? Thats like saying: Are we crashing? No, its just a rapid decent.>> <<@6teeth318-w5k says : Bobsleigh ina tunnalz.>> <<@blackice9088 says : Some of the original computer graphics for the HYPErloop showed 90 degree turns in the tubes! A projectile travelling at over 700 miles an hour is NOT going to make a turn like that! It would crash right through the tube, or end up looking like a crushed soda can, or both! 😂😂>> <<@DailyCorvid says : Should have called it the Lie-perloop. Bullshit travels at around the speed of sound, so it might work!>> <<@manoz6194 says : Imagine vandals messing with the tube.>> <<@peterskove3476 says : It won’t work in the states because we are not metric.>> <<@kuei1215 says : The Theranos machine looks just like my ice maker.>> <<@hobo1704 says : Elon is an absolute muppet..>> <<@tullochgorum6323 says : So this aged well then. As I write, just 3 years later, Hyperloop One, all that remains of Virgin Hyperloop, is 3 days away from shutting down for good.>> <<@blackice9088 says : So they're inviting comments but then they turn comments off? Brilliant!>> <<@shaider1982 says : Thunderf00t wins, flawless victory.👍>>
