The Hyperloop: BUSTED!

Thunderf00t isn't just some average Joe on the street. The guy has a PhD in chemistry and has dedicated a decade to educate the world at large about matters of science and intellectualism. The world would be a better place if we had more Thunderf00ts on YouTube. His videos on the hyperloop are pretty comprehensive and succinct about their reasoning. Why not watch them instead of mindlessly repeating the same strawman argument that every other Elon Musk fanboy/fangirl left on his videos? [LINK] [VIDEO]

I'm happy for them, but I'm yet to hear for anybody to address the major challenges that many people have raised. The major one being - the sudden pressurization in any point and the consequent shockwave traveling at the speed of sound, exploding the tube, killing everything in its way. Thunderf00t did a good job summarizing the problems: [VIDEO]

I think this needs to be brought to more people's attention, so I'm putting this in a top level comment: Thunderf00t's video: [VIDEO] Debunked: [LINK] Also debunked: [LINK]

The best legitimate criticisms I've seen are here: [VIDEO] Basically expansion and contraction as well as just plain vulnerability of running a vacuum make it extremely difficult to do practically. The phrase he uses, "all the problems of space travel except in a gun barrel" is a pretty accurate description of the issue. Any loss of vacuum will almost guarantee loss of life. No realistic demo has been done even on a small scale as of yet.

The tone and sarcasm of this video aside, the guy makes strong arguments that the Hyperloop cannot work technically. Worth watching as he makes good arguments. [VIDEO] edit: actually it can work technically, but it's not practical at all

If you haven't seen the technical criticisms of Hyperloop, Thunderf00t has an interesting video: [VIDEO] I haven't seen most of the issues he raises addressed.

It is infeasible, if it's going to be vacuum, for a pile of practical and safety reasons: [VIDEO] Maybe it will pivot into something not-as-originally-hyped by the same name.

1. Pressure. 2. Speed. 1600 km/s is pretty snappy. Thunderf00t tends to wibble on a bit and repeat repeat himself, but he does make his point. Relevant bits start about 6m22s. [LINK] Or at 10m28s in this video: [VIDEO]

Thunderf00t has a good video on the problems with it. [VIDEO] He has some other good videos (solar roadways) but tends to spend to much time bashing creationists.

I don't know why they're doing this, except out of pure tech-broism. It's obviously not financially viable. Let's say it realistically costs $150 million a mile for the project (about average for tunnel boring - it'll actually be a lot more on the east coast due to it being solid rock and expensive labor, but let's be realistically optimistic). At 250 miles, that's $37.5 Billion right there. Let's be ridiculously generous and finance this over 50 years. Over 50 years, that's $750 million/year. Or, $2million/day. At $60/ticket, you need 34k daily riders. And that's only for building the tunnel. I haven't even factored in operating or finance costs, nevermind the millions of other expenses that this needs. Stations are normally the most expensive part of a system, for example, and a station in NYC might cost $1 billion by itself. Is this going to get 34,000 daily riders paying $60/ticket to NYC? I can see that happening with $10/ticket, but not at $60/ticket. For comparison, the entire DC Metro system itself has about 800k daily riders with about $5/trip. And then you have the stupid HyperLoop concept itself, which hasn't even been invented yet. It's based on small single-car vehicles, which may carry a couple dozen people at most. Already you can see capacity issues: To get 34,000 people a day 24-7, you need 1400 fully-packed rides a day, or one every 6 seconds. You're not going to get single-vehicles to share a track every six seconds. You're already capacity limited. How do

British scientist Philip E. Mason ( thunderfoot ) made several skeptical videos on Hyperloop. [VIDEO] I highly recommend his whole Busted! series.

A lot of his ideas are full of holes: Hyperloop: See all of the problems here: [VIDEO] Boring company: summary of issues here: [LINK] SpaceX: How will we fund the amount of rocket fuel required to get the stuff to Mars that can produce an atmosphere? If producing an atmosphere isn't required, then how will indoor atmosphere be maintained sustainably (financially)? Matt Damon's math didn't seem to work out in that movie... Tesla: So far so good, but what about battery recycling? “We are at the very beginning in energy storage in general,” says Phil Hermann, chief energy engineer at Panasonic Eco Solutions. “Most of the projects currently going on are either demo projects or learning experiences for the utilities. There is very little direct commercial stuff going on. “Elon Musk is out there saying you can do things now that the rest of us are hearing and going, ‘really?’ We wish we could but it’s not really possible yet.” [LINK] SolarCity: Just look at the customer reviews so far: [LINK] I would urge Mr Musk to focus on Batteries & long-term Tesla ownership. It would be a shame for that not to work out! I hope this comment lasts for 5 years :)

related topic: Elon's "Hyperloop" project has gained a lot of criticism too. Many [1] long video essays have been made to debunk why it's not a good invention. Now the hype has died down considerably and it seems a lot of people have lost faith in the idea... maybe they're losing faith in all of Musk's ventures... [1] [VIDEO]

Elon wields a powerful influence, a cult following. Fault is a fuzzy concept, not restricted to binary blame. Combine the poor taste of Elon fucking around with a monetary instrument, and his cult risking their life savings on his every word, and grave losses are the result. People commit suicide all the time because of large investment losses. Don't be too quick to doubt the monetary and biological loss in the US and abroad his statements likely caused. Your argument hinges on Elon not being the "hand that pulls the trigger." It's really irrelevant as everyone on HN is intelligent enough to understand that Elon is responsible for his reckless persuasions of a populace that is on average, stupid. Yes, the average person is... stupid. Especially ones who worship this man. Here is just a fraction of Elon's record: [1] Pedo Tweet: [LINK] [2] Hyperloop Scam: [VIDEO] [3] Boring Tunnel Scam: [LINK] [4] Autopilot Scam (11 confirmed deaths - should be called Enhanced Cruise Control instead): [LINK] [5] Founder of PayPal, a platform that has been freezing and stealing user's funds since 1998: [LINK] [6] Not even the founder of Tesla. He was an investor (using his grifted Paypal money - how many frozen accounts did it take?): [LINK] [6] Anti-union: [LINK] [7] Does not care for wellbeing of employees: [LINK] Elon is not Tony Stark or Iron Man. He is not a hero. He is not a villain. He is a highly intelligent man with many blind spots and a penchant for rash, poorly judged decisions. For

Apples and oranges false equivocation of vastly different engineering problems. The problem with vacuum trains is they aren't workable with current materials, are impractical, and are too damn expensive. [VIDEO]
