Boring Company Approved To Build Futuristic Garage That Would Connect To Underground Commuter Tunnel (mercurynews.com) 89

On Tuesday night, the Hawthorne City Council gave Elon Musk's Boring Company the green light to build a prototype for a new garage that would connect passenger cars to the entrepreneur's envisioned underground hyperloop. The Mercury News reports: Musk's Boring Company recently bought a private residence abutting the one-mile underground tunnel it already built beneath 120th Street between Hawthorne Boulevard and Prairie Avenue near SpaceX. The garage at the residence would connect to the tunnel. But as part of its approval, the company agreed not to open the test elevator to the public or to have cars move in and out of the garage from the street. Cars would enter the tunnel from the SpaceX campus, move through the tunnel and on to the garage and then back to SpaceX, so the test process would not create additional traffic on the street. The company wants to show that it can utilize an elevator and short tunnel spur for developing a high-speed underground public transportation system. It plans to rent the house as well.

As sketched out in public documents, a car would drive onto a "skate" that connects to a hyperloop track, such as the ones being developed by two private companies and recently featured in the collegiate Hyperloop Competition at SpaceX. The company also on Tuesday earned approval for a separate short spur from its existing tunnel in order to remove a boring machine that it first intended to leave in the ground. Originally, the company planned to bore a two-mile length of tunnel, but as company representative Jane Labanowski explained to the City Council, they identified an opportunity to remove its expensive cutter head. So, it now plans to reduce the tunnel length to just one mile and extricate it from another piece of property the company recently purchased.

      We assumed it was in CA otherwise Musk would have to dig a very long tunnel to connect it to his Hype R Loop

    Here's to hoping that we soon get more info about their surface connections. Because they've talked almost nothing about them and to me it seems like the hardest part. Loop, in their ultimate design goal, fundamentally requires large numbers of these surface stations (in contrast to subways that use a smaller number of large terminals), so you have to be able to build them quickly and cheaply. You obviously can't make them with a TBM, it's not just going to make a sharp right-angle turn and drive vertically to the surface. And while the main tunnel can be as deep as you want in order to avoid city infrastructure, every single one of the surface stations has to penetrate every layer below it en route to the Loop tunnels.

    I really want to see what their approach is to be able to rapidly make the vertical tunnel segments while quickly detecting and avoiding or rerouting any unmarked underground hazards or infrastructure. Their ease of getting permits en masse will depend on how well they can demonstrate causing minimal disruption to everyday life. To me, this sounds like the hardest part of the whole Loop goal.

      In addition, these surface tunnels can't just drop straight into the main loops. To be able to carry any real volume in the main loops, you can't have acceleration occurring on the loop. If you accelerate on the loop, you have to maintain a ridiculous gap between vehicles to allow for a car or carrier to enter the loop and accelerate before being rear ended. The throughput would suck.

      The solution is to have lots of acceleration and deceleration tunnels that merge with the loop and some automated management of the merging process. Given that tunnels are planned to be cheap, this is likely the intended solution.

      So a connection involves an elevator to get through the crud closest to the surface using the shortest route (straight down cuts through much less crud than ramping down) connecting to a ramp that leaves the loop, passes a bunch of elevators, and rejoins the loop.

      Extra points to anyone who can design an off ramp that splits off in such as way as to make it impossible for any vehicle to ever hit the divider because that is the only point in the system where a head on collision with a wall could happen.

        Indeed - "feeder tunnels" and onramps/offramps are an explicit part of their plan. That's a relatively straightforward part - just more boring, at depth. It's the vertical access shafts that they've not talked much about, and which seem to be the trickiest part. So here's to hoping for more info about their approach here.

          Yup agreed. The elevators will be the part of the system that gets congested most easily and I've yet to see any info as to how they're planning to avoid having long lines of cars waiting to be taken up/down on the entrance/exit points while also keeping the costs reasonable.

          This is where the whole project stands or falls. It doesn't matter

          • by Rei ( 128717 )

            The plan is to have them be so numerous that there are rarely ever "lines" of more than one car - simultaneously also enabling much of a direct-to-the-destination mode of travel. Which again, is why it rises and falls on how well they can accomplish this loading step. If an elevator takes 1 minute per loading, which (between cars and passenger capsules) averages 3 passengers, then the maximum daily passengers from that terminal is 4320. So for it to be the only means of transportation for a city of 1 mill

              Assuming uniform loading for capacity factors is erroneous. People take more trips at 8AM than at 3AM or 2PM. Adding more station density out at the edges of San Jose doesn't help capacity in the downtown at rush, too.

              • by Rei ( 128717 )

                925 assumes both uniform loading patterns and that Loop is the only means of transit in the city. 3-5k is my estimate for accounting for both of these factors.

                • by mlyle ( 148697 )

                  Really IMO population isn't the place to start. Figure out how many people need to get into a commute target in how much time. Then figure out if the station density for that place is practical.

                  Probably the worst thing is the asymmetry in station loading--- you need lots of relatively low-use stations to minimize walking distance, but you need lots more stations than that in the densest areas to deal with queue lengths during peak demand (and they will tend to only be full in one direction at a time).

            • If an elevator takes 1 minute per loading, which (between cars and passenger capsules) averages 3 passengers, then the maximum daily passengers from that terminal is 4320.

              It's far worse than that, because there are big spikes in traffic at certain times of the day and other times where there's almost no one on the road and no traffic that would cause a person to use this service unless it's overall less expensive. However, it doesn't need to be able to hold the entirety of all traffic, just enough to reduce congestion on the main roadways where everything is jammed up. Also, there's nothing that says you have to design a system that can only load a single vehicle at a time.

                You mean like where I wrote "Increase that figure (significantly) for the fact that you can't expect it to always be at 100% usage *and* not generate lines. Decrease for the fact that nobody would expect that to be a city's only means of trasportation. On the balance I'd think that a city of 1 million would need at least 3000 terminals, preferably more like 5000 ter

        Aren't these things mag-lev rails? Construct a magnetic field flush with the divider making an apparent seamless wall.

        Tech probably isn't there, but this would probably be one of the only routes to meet that goal. It would have to be fast enough to turn on/off in a mome

          Loop is not maglev; it's wheels or rails. Some technologies using the "Hyperloop" name are maglev, but the original Hyperloop proposal is air bearing-based.

    • I think this is one of the reasons that a lot of the entrances have been envisioned as being from garages or parking lots. There is a lot less running under those locations than under the streets. Keep them deep and the tunnels can use the right of ways of the streets, but the downshafts will be going down to the sides of all of that mess.

  • By now we should've had a fully working 100 mile prototype, all we have is a 1/10 scale model that runs a few hundred feet and takes hours and hours to start.

    I think Elon is 'quietly' retiring the failed enterprise.

    • by mentil ( 1748130 )

      A competition held a couple months ago used a 1-mile test track in a 6-foot-diameter tube. It's expected to be half the diameter required for the real thing, but it was evacuated of air so it's not too far off from the production tube characteristics. The maglev aspect is only starting to get traction (ha!), with a 75-foot test track; speeds should pick up once maglev is incorporated, compared to the most-publicized test vehicles which use wheels.

      • Whatever happened to the compressor/air-suspension concept rather than the mag-lev concept? To me if it's mag-lev then it's not real Hyperloop.
        • Air-suspension doesn't really make sense in an evacuated tube. They're trying to eliminate the air, not use it to lift the pods.

      • by guruevi ( 827432 )

        Half the diameter = 1/4th the volume required. That is, you either need to pump out a volume 4 times as long or as fast (which took 45 minutes with the biggest vacuum pumps commercially available).

        Maglev has been figured out, go to Japan, get a train and some track and bring it back.

    • by Ksevio ( 865461 )
      If you're building 100 miles, it's not so much a prototype. They have plans to build one in Chicago to the airport [techcrunch.com] and a smaller one in LA to the Dodger's Stadium [techcrunch.com].
      • by guruevi ( 827432 )

        Plans, yes, but they haven't even fully built out a one mile test track 1/4 the volume of their final product.

        The hyperloop idea isn't new or hard. We've figured out Maglev, we've figured out vacuums, the test tube should've been a one-year project.

  • Maybe it's because I'm approaching "get off my lawn, kids" age, but isn't this whole concept of a loop tunnel infrastructure simply a fantasy of those living inside the Silicon Valley bubble? Seems like a solution looking for a problem, a huge suck of public funding for the benefit of very few people who'll use it. Crazy idea: improve, update and modernize the mass transit options available now.
  • Another step towards Caves of Steel ... fine with me.

    Nature is overrated. (And it tries to bite you too much.)

  • Funny company going to provide all the balloons for the big opening.

  • Oh so they've solved all the hard problems and can go on to the easy stuff. Cool!
    Like how to keep such a hyperloop evacuated over hundreds of miles with connections and evacuation routes, and implosive recompression not ramming into the train like another much larger and more violent train.

    • A garage that doesn't exist for transport technology that doesn't exist. I'm going to have pilotless drone taxis bring people to the hyperloop, don't invest in that garage invest with me! bitcoins accepted, just make sure it's $1000 or more in bitcoin!
