    Hello Everyone!

    Elon Musk (Paypal, SpaceX, Solarcity, Tesla Motors) has said that one of his potential next projects would be a new mode of transportation he calls the "HyperLoop", which he hinted would be a cross between a Concorde, a Railgun, a Air Hockey Table.

    Does anyone have an idea what it is or what it might be?

    EDIT:
    Apparently it would travel somewhere close to the 700 MPH range (over 1100 km/h ! )
    (Travelling 380 miles in 30 min)

    Im wondering if it really has to be an underground tunnel (high cost) has opposed to a suspended structure like some form of monorail?

    I found other tid bit clues" Musk said in an interview with CNBC Friday that California's massively expensive high-speed rail project got him thinking about it. He criticized its slowness, at least compared to similar systems in China and Europe, and its cost, which may be as high as $100 billion.The Hyperloop, on the other hand, will be blazing fast, getting people from Los Angeles to San Francisco in under half an hour. And, he says, "it can be done for probably a tenth the cost per mile." "

    (Im no expert, but if the cost is that much less than whatever high-speed rail is being compared, i dont think it would be underground, typically underground tunnels are much more expensive than overhead monorails, right?)

    They've had the idea for quite a while of using magnetically lifted and accellerated trains in vacuum tubes, meaning that they can make them travel much faster without any wind resistance, don't know if perhaps this has anything to do with it.

    Facepalm! Thanks, I should have looked (wikipedia) there first! it was so un-announced and sketchy I never thought there would already be an article about a non existant undisclosed thing!

    Apparently it is somewhat different from a vacuum tube maglev?

    Other quotes from wiki

    This system I have in mind, how would you like something that can never crash, is immune to weather, it goes 3 or 4 times faster than the bullet train... it goes an average speed of twice what an aircraft would do. You would go from downtown LA to downtown San Francisco in under 30 minutes. It would cost you much less than an air ticket than any other mode of transport. I think we could actually make it self-powering if you put solar panels on it, you generate more power than you would consume in the system. There's a way to store the power so it would run 24/7 without using batteries. Yes, this is possible, absolutely.
    —Elon Musk, July 12, 2012
    "What you want is something that never crashes, that's at least twice as fast as a plane, that's solar powered and that leaves right when you arrive, so there is no waiting for a specific departure time," Musk says. His friends claim he's had a Hyperloop technological breakthrough over the summer. "I'd like to talk to the governor and president about it," Musk continues. "Because the $60 billion bullet train they're proposing in California would be the slowest bullet train in the world at the highest cost per mile. They're going for records in all the wrong ways." The cost of the SF-LA Hyperloop would be in the $6 billion range, he says.

    We should have more details later today, but in the meantime heres an interesting video about a square tube design

    Heres the alpha version of the concept

    God bless capatalism, for it affords the chance of a small percentage of visionaries achieving success and thereafter not realising some objectives are unattainable, and thereby forging ahead until they attain them. (Yes, shorter sentences would have been better, but you get the drift.)

    Hum, ok. Does anyone have engineering/construction/technology comments about the concept?

    Its propelled by a linear electric motor like effect at regular intervals (of many km) and the pod has an battery electric engine that sucks air in front and pushes it out the back and out on skis to make an air cushion?

    Could the skis be magnetize to repel metal from the tube? or could the craft be shaped so that ground effect would be comming mostly from the shape of the craft rather than air out of skis?

    What are the advantages of using a cylindrical tunnel instead of a square one? In turns the cyclinder allows the craft to roll, is that better? Is it easier to achieve ekranoplan-ish passive lift in a square tunnel?

    The compressor in front is like an electric version of a jet engine, taking air in front an pushing it in the back?
    The concept calls for a battery pack in the back powering the electric jet engine, but can the tube recharge the battery as it goes along like an electric train? Like Wireless recharging?

    Yes, I too would like to see the opinions of some engineers here

    For anybody interested in the PopSci article on this topic.
