Josh Giegel: Super speed, magnetic levitation and the vision behind the hyperloop | TED
What if your hour-long commute was reduced to just minutes? That’s the promise of the hyperloop: a transit system designed around a pod that zooms through a vacuum-sealed space (roughly the size of a subway tunnel) at hyper-speed, powered by next-generation batteries and state-of-the-art magnetic levitation. In the visionary talk, Josh Giegel, the hyperloop’s very…

But the hyperloop was already debunked because of the following two reasons.
1. The cost to build and maintain a constant vaccum in a tube stretching cities would be an order of magnitude more expensive to operate than it would a high speed rail network than spanned the entire United States.
2. Repressurization due to a single fault or general wear and tear would be enough to kill everyone currently in the tube (do people actually know how violent vacuum repressurization is?)
I get that the US failed to build an actual decent passenger rail network, but that doesn’t mean you need to jump the shark with this hyperloop nonsense. It’s investment bait / snake oil, sorta reminds me of that Simpsons Monorail episode…but somehow more needlessly expensive and dangerous.

@Vcat417 – Channel ” All is intertwined ” indeed, for all the high tech wonders we enjoy, there was a period when it was expensive, unwieldy, and unreliable all at the same time. I costs a ton to make an idea practical. But an honest and thorough analysis of the hyperloop, as per Thunderf00t, shows how little you get for moon-shot level efforts. It’s not hard to decide that $10 billion is better spent on more sensible endeavors, like regular high-speed rail. I think you’d enjoy Thunderf00t’s “high-tech debunking” videos. For real, check out his smack-down on atmospheric water machines!

@Vcat417 – Channel ” All is intertwined ” Tesla didn’t invent the concept of self driving cars… They’ve been working on them since before Tesla existed as a company. Also, they aren’t exactly in the lead, waymo is currently the only company in the US that has vehicles on the road that are completely autonomous / don’t require any human attention. Cruise and a couple others a pretty good too. This comment is wild.

@For An Angel Technology improves, but the laws of physics don’t. It’s impossible to build, operate and maintain a hyperloop and be more cost effective (and as.practical) as a simple rail network. The hyperloop is basically the engineering equivalent of designing some elaborate rube goldberg machine to hurl people over a river, when the obvious thing to do would be to construct a bridge.
Just because you can do something, doesn’t mean you should. Energy required to run a constant vacuum (and maintain all the machinery to keep it running) will ALWAYS be orders of magnitudes more costly than to simply lay down some rail tracks that have no moving parts.

Hyperloop is a waste of resources. No one needs a personal vehicle to travel at extreme speed. Everything, including human effort, can be delivered remotely. There is literally no vision behind this commodity. It’s actually supported almost entirely by a severe lack of vision. Unnecessary technology that will very shortly serve no purpose whatsoever.

Regular rail >> High speed rail >> Maglev >> Hyperloop.
Don’t jump to the end of the tech tree when haven’t even got enough of the first two. A Hyperloop is difficult and SUPER expensive to make, but even worse is how expensive it will be to maintain. The money spent on keeping it in working order could pay for so much regular rail. We can’t do a Hyperloop. The only way is to make people not mind a long rail journey.

If we had just invested in the Shinkansen here like the Japanese did, then we’d have fast electric trains 30 years ago.
I dunno but if this was so great other countries that already use trains much more would have one of these.
And there’s another solution for human contact that takes zero time, is free, has no environmental impact, is boundless and available already .. video meets. hard to compete with that.

I think its proof enough that Japan with their ridiculous(in comparison to north america) public projects budget, which has had huge funding into things like shinkansen, and is going to roll out SC maglev, in the upcoming years, HAS PUT NO MONEY into this ‘idea’ which has existed for years. I mean, the cost of the vacuums alone is enough to make planes more viable… you know what planes are beat by… FUCKING TRAINS. TRAINS THAT HAVE EXISTED SINCE THE 60’s. SINCE THE FUCKING 60’s. MAGLEV HAS ALSO existed since the 80’s, and high speed maglev in shanghai rolled out, or levitated out in 2003… WHO IS BUYING THIS, WHO IS BUYING THIS? Who is the sucker that happens to attempts to pass this on. GOD DAMN IT. IM actually pissed. TED, i understand that you dont care about who speaks as long as they “bring new and insperational idea” or whatever but DO YOUR FUCKING RESEARCH. the pain of watching this guy who seems to have deepthroated the fucking koolaid and is now attempting to pass it on since he cant get back his old job, because he literally didnt take the time to do 5 minuites worth of math. If these people believe that they are able to make space grade seals on a system that will be Overloaded with vibrations is crazy. If they were at all smart they wouldnt attempt to make “hyperloop” becuase of 1. the cost of vacuums, 2. the inefficiency of 2-4 person ‘pods’ and 3. because an innovation in the vacuums, vacuum seals, or maglev alone would be more than enough to turn any of these companies into stock whales, worth their weight in blue chip stock. but no… instead of choosing one of these fields, they waste time trying to combined them. its like trying to make silverware, but you dont even know where the silver is.

The Wright brothers invented powered flight like Christopher Columbus discovered America. It’s a legendary cliché.
A closer look at the events of the time reveal that just like for the electric bulb or the telephone, many pioneers were working on the same goal.
The Wright brother’s genius was that they thought of inviting the press while other inventors didn’t..

Shame on you Ted, allowing someone on that just wants to help peddle what has been debunked AND demonstrated IN REAL LIFE, that it’s waaaaaaaaay too expensive and impractical to achieve. Hyperloop needs to be buried, but just deep enough that people can still see it’s remanence and be reminded how dumb of an idea this really was.
Thunderf00t here on YT has made quite a few videos explaining everything and why Elon Musk should not be trusted on MANY levels. It’s actually quite scary how many Musk fanbois there are and don’t care about actual science that ISN’T backing him.

The problem will be getting the land, the permits, the sound proof, where the power comes from, where do we put the stations and what stations are needed (cuz if NY to LA has 27 stops it really slows down everything) and everything in between to get it done.
