The Smog To Fog Challenge: Settling the High-Speed Rail vs. Hyperloop Debate

waderoush writes "Elon Musk thinks California should kill its $68 billion high-speed rail project and build his $7.5 billion Hyperloop instead. It's a false choice. We should pursue all promising new options for efficient mass transit, and let the chips fall where they may; if it turns out after a few years that Musk's system is truly faster and cheaper, there will still be time to pull the plug on high-speed rail. But why not make things interesting? Today Xconomy proposes a competition in the grand tradition of the Longitude Prize, the Orteig Prize, and the X Prizes: the $10 billion Smog to Fog Challenge. The money, to be donated by big corporations, would go to the first organization that delivers a live human from Los Angeles to San Francisco, over a fixed ground route, in 3 hours or less. Such a prize would incentivize both publicly and privately funded innovation in high-speed transit — and show that we haven't lost the will to think big."

    Shaving 35 minutes off a five hour trip is really easy if you drive reasonably (i.e. non-dangerously) fast.

    In fact pretty much all the time I am somewhere five-ten minutes per hour faster than the Google estimate.

  15. Re:It's the Right of Way that's the problem. by Immerman · · Score: 2

    Actually one of the benefits of the Hyperloop idea is that it's designed to follow the existing government-owned highway right-of-way except for in a very few places where its path winds too much to allow for the high pod speeds. This is actually an advantage shared by most elevated transport systems - since it's relatively easy to span 100 yards or more between pylons there is minimal impact at ground level which radically reduces both land acquisition and preparation costs, as well as radically reducing environmental impact in sensitive areas and the difficulty of passing through already-developed areas. A farmer is extremely unlikely to be willing to sell a strip of land to build a road that splits his farm in two, but might be far more receptive to selling a few small plots of land to build pylons on and a right-of-way through his airspace. Especially for something like the Hyperloop where the near-vacuum tube and air-bearings should make passing pods fairly quiet and invisible

  16. Don't Forget: Excess Electricty by wjcofkc · · Score: 3, Interesting

    In this debate, people have forgotten an important point that Musk made early on: In being solar powered, the system is expected to yield enough excess electricity to make it worth contributing to the grid. I'm not going to get into the debate itself, but for those of you tossing the ball back and forth, you should consider this point in your arguments, whether you think that particular claim is feasible or not.

  17. Re:What about capacity by Animats · · Score: 2

    The largest issue I have with the hyperloop proposal is its rather pitiful capacity. At the highest rate proposed, with one cart every 30 seconds it still only transports ~3600 PAX/hr, which is about on par with a 3 lane highway and that is before mixing in the car carriers.

    Musk writes in his proposal: "Assuming an average departure time of 2 minutes between capsules, a minimum of 28 passengers per capsule are required to meet 840 passengers per hour." So it's even worse than 3600PAX/hr.

    Compare current flight capacity. At peak, there are 5 flights an hour from SF to LA. The most common plane on that run is a Boeing 737 with 137 seats, for 685 seats/hour. So the Hyperloop has more capacity than the current aircraft. Comparing with other tunnel systems, Eurotunnel moves about 30 trains per hour, and their trains are 400 meters long with a seating capacity of 750 on the passenger-only Eurostar trains. Hyperloop is way below those levels.

    Overcapacity is a big issue for US high speed rail. It's not clear there's a market for far more passenger transport between LA and SF than is currently available.

    Even at the low rate, there's a Hyperloop capsule every 2 minutes. It's not clear you could reduce that interval by much. The capsules to be at least one emergency stop distance apart, plus a safety margin. Also, the stations will need multiple tracks and airlocks, so that loading and airlock pump-down time can be overlapped for multiple trains. The system will definitely need low-speed switches (not too hard) and maybe high-speed switches (big, but buildable). Musk oversimplifies those issues.

    It's amusing that the proposed location of the "San Francisco" station (p. 51) is not in or near San Francisco. It's near Musk's Tesla plant in the East Bay.

  18. Simple math by jklovanc · · Score: 2

    My main issue with the tube technology is that all the articles seem to assume that the tube will be straight. In the real world there are very few straight lines. Between any two distant points there will be mountains, valleys, cities, rivers, hills, houses, etc. The tube will not be straight unless you want to build it underground all the way then it becomes very expensive. Even underground there will be issues with valleys where the tube may have to be suspended. To me it is a given that the tube will have to have curves in it which brings me to the math of curves.

    The acceleration of an object moving along a curve is a= v^2/r or r = v^2/a. If the object is moving at 600kph and we want to keep the acceleration to 1/2G at most the radius would be 167^2/4.9 = 5.7 km. That would mean to alter course by 45 degrees it would take 9kms. That is a very long curve. It is even worse in that the curve would have to have an in run and an out run to make the transition manageable. Remember that these curves are not just left and right. If one goes over the brow of a hill negative G's could be an issue. The human body can not handle feeling lighter very well. people get sick pretty fast.

    To keep these smooth curves there will be very few places where the tube will be sitting on solid ground. Much of the time it will be under ground or suspended in the air. Both of those make construction and maintenance very expensive.

  19. Re:Libertarianism is also such a failure. by khallow · · Score: 2
    I read this and it just sounds like a parody of human thought. Paying taxes is a "relationship"? That's a mockery of the word. Though I must admit that I wouldn't mind enjoying the same relationship with your bank account that your favorite tax collection agency has. But maybe you should put a bag on your head first.

    And all these straw men libertarians? Can't say that I really care what you think there. One can study actual libertarian philosophy, discussion and such. What you claim just isn't true.

    For example, let's consider your second to last sentence.

    Libertarianism is for people that doesn't know that it's ok to sacrifice a pawn (their taxes) to save the king (their health care), for example. They don't know that government is a giant Costco that actually benefits them in the long-run, because they see the incremental failure that is them losing tax dollars. Libertarianism really is about the "me first, then others" philosophy. It is intrinsic to their failure.

    So here, there's some naive notion that government is a giant store where you get more out than you put in. Ignoring that this analogy is so broken as to be unrecognizable, where's the demonstration that you will get more out than you put in?

    Last I checked the US government together with the assistance of about every developed world government has the capability to spy on every phone or internet connection in a vast part of the world. I don't want that in my shopping cart. That's what your Costco delivers. You may not have noticed, but libertarians tend to be very paranoid about this sort of thing. And I think there's great reason to be fearful of what the governments of the world will do with this power.

    Then there's the problem of governments not following the rules. A lot of people get that it's bad when businesses don't follow the laws and aren't punished for it. But who's supposed to be enforcing those laws? It's not the libertarians screwing this one up, but the same government providing all those Costco benefits.

    You are looking at it in the wrong terms. The majority of individuals get more out than they put in. Those who don't are not greatly harmed because they are still rich. In fact those who get less monetary value out for their own personal use still benefit from living in a relatively content and healthy society.

    You, like many people, made the mistake of trying to put a dollar value on everything. You know the price of everything and the value of nothing, as we like to say.

    There is also the assumption that having private companies provide services at the request of individuals would be more efficient than having the government doing it. Apart from the difficulty of organizing certain services there is no evidence that this method would be any better. Do you have any evidence?

    yet liberals couldn't give a damn about society as a whole, so long as money is being transferred from the affluent to the less affluent.

    It's not about transferring wealth. It's about stopping theft.
