  • World's first full-sized Hyperloop Capsule Unveiled in Spain

    The first parts for the Hyperloop track in France are also in construction since April 2018.

    (German but you can see the tunnel segments on a truck)

    Hyperloop explained

      Call me a cynic, but I do not believe that some of the engineering problems present can be easily solved in this day and age. How will a pressurized system of any significant length (say, 100 km) handle thermal gradients, storms or earthquakes? How much energy will be spent in order to maintain a near vacuum in said tubes via a continuously running vacuum pump (since leakages will inevitably occur)? What about possible sabotage of the pylons or the tube by beardies? What if there is an accident while a capsule is underway or the capsule depressurizes? What about the maintenance costs involved?

        Of course they made feasibility studies first. Like Virgins One







        Ther are many hyperloop developments at the moment.

        The TU Munich also designed a vehicle

        WARR Hyperloop Alpha

          I'd like to know that as well.

              Same as in airplane. If there is accident system will automaticaly engage breaks and begin to pressurize the tunnel. The capsules will also have wheels and independant propulsion for emergencies.

                I assume few know about this, so I'll provide a link (I searched one for the pictures):

                World's First Hyperloop: Henri Coanda's Hyperloop

                I remember reading elsewhere that a person traveled in the "loop" (unofficially since it was not cleared to do so, if the story is right). He described the experience as being really loud.

                Bottom-line as far as I'm concerned, can I use it like I do with any train or subway (ease, comfort)? No, then I'm not that interested...

                I don't want a slower alternative on land to a cramp and noisy plane.

                  I'm thinking it will go something like this:


                  Hmm, why not just use the method to move the pod.

                  No need for fucking magnets, how do they work.

                    I'm sure it's... Doable, but I just can't shake the "Thunderf00t" tirades on the matter... He raises some good points, and has visited the various testing sites (and he more or less laughs at the entire thing).

                      Dunno sounds like a 21st century Hindenburg waiting to happen.

                        Any damage, even tiny ones, on the tube will cause spectacularly horrifying results. Anything inside the tube will be demolished with a sonic boom. Like said earlier, It will not work, the requirements are just way too precise. No sane person would take a ride on it, even they somehow would be able to make a working one.

                          What damages should it have? Little tiny cracks? We check aircarft parts for that since decades. And an a/c is way exposed to cahnging loads and dynamic abnd staic processes.

                          Yet of these thousand upon thousands of a/c fdlying everyday multiople times. They very seldomly have structural failures.


                          But it wil have to be inspected throughly but as it is a tube you can build an inspection vehicle going through the tube and making xray or eddy current checks for example.

                            Dr. Philip Mason (aka "Thunderf00t") is still laughing at everything "Hyperloop":



                            It's his ...5th video trashing it over past couple of years, but yeah... Still valid points.

                              Generally, I concur with his views. However, he made one slight mistake in saying that humans can't survive in vacuum. I have read research papers from the 60s-70s (the heyday of space research) which showed that primates can survive for up to a minute in case of decompression from 1 atmosphere to 0. Essentially, the delta_P of 1 atmosphere is insufficient to cause "explosion" of an individual (such "explosions" only occur at much higher delta_P, say for a diver being instantly decompressed from 10 atmospheres to 1: https://en.wikipedia.org/wiki/Byford_Dolphin ). This means that if someone were to step out into the vacuum of space - they would be able to survive for up to a minute and eventually die by asphixiation (and not "explosion" or freezing). Even the 0 K temperature will not be as deadly as first imagined because only the radiative heat transfer (the least effective one) will be operating (no convective or conductive), so stepping into the vacuum of space won't be equivalent to dunking yourself into a vat of liquid hydrogen..
