Elon Musk Posts New Video of 'Boring' Equipment and Company's First Tunnel (cnbc.com)

Elon Musk has posted a new video and several pictures of equipment that will be used to start digging tunnels beneath Los Angeles. There's a picture of boring machine segments that are being lowered into the start tunnel at SpaceX, a front view of the tunnel, an inside view of the tunnel, and a picture of the front of the boring machine that will cut through underground rock. Additionally, the video shows a version of the "skate" that will cary cars through the tunnel at a speed of 125 mph. CNBC reports: The project is one of Musk's latest ventures, which was inspired by a desire to alleviate "out of control" traffic in Los Angeles. He aims to first dig a tunnel from SpaceX headquarters in Hawthorne, California, to the nearby Los Angeles airport. Musk frequently flies from Los Angeles to the San Francisco area, where he runs Tesla. Eventually, he envisions a deep, multilayered network of underground tunnels spanning the city.

      Every state requires permits to dig transportation tunnels.

      Musk would need building permits from the cities of Hawthorne (SpaceX HQ) and Los Angeles (LAX), plus a permit from California's OSHA. There would need to be a public hearing and an environmental impact report. Los Angeles has also said that any tunnel under a public right of way needs city council approval. Hawthorne has been talking with SpaceX about a pedestrian tunnel linking the SpaceX building to a parking garage in an adjacent lot. That is the only thing they have been discussing, no vehicle tunnel has been mentioned. When Hawthorne recently contacted SpaceX about this LAX tunnel, they were told that a hole does exist on their property but it doesn't go anywhere. The city advised them that anything deeper than 5 feet would require a permit.

      Musk has admitted he doesn't know what he is doing, that this tunnel was just an idea he had. Unfortunately for him induced demand has been well studied and building more roads or lanes doesn't reduce congestion.

The surface and shape of the foils can have an effect on noise. Ducts can cause the same effect as larger props (increased air mass at lower speed). Any sort of properly designed cowling can reduce noise. Reduced blade thickness (aka, stronger materials, which we get all the time) reduces noise. And on and on.

      An Elon Musk project where the engineering "details" haven't come out yet? Tell me it ain't so.

      One has, however, which is simultaneous casing and boring, rather than bore/stop/case. There's a number of changes to the head that they're looking to make, but they haven't been discussed yet.

      Simultaneous lining and boring has been a done deal for decades. I refer you to the Channel Tunnel.

      I don't know what kind of bedrock they would be boring through but they all come up against something they didn't expect. Doesn't matter if it's sedimentary or metamorphic rock in the case of the English Channel or igneous rock in the Swiss alps. Add to that an area that is prone to earthquakes....piece of piss, right?

      I think I've seen enough of Elon Musk to determine that he is full of shit and preys on people who know precisely fuck all about engineering...or anything else, for that matter. That includes the politicians who give him vast subsidies for whatever is the latest delusional bollocks he happens to come out with.

      Absolutely correct.

      As someone who worked on the Channel Tunnel at the dirty end, I can confirm 'simultaneous' lining and boring has been carried out for the last few decades.

      However, there will always be an cyclic element to the operation as the Tunnel Boring Machine (TBM) has to push off of something to get thrust forward and that is usually done by hydraulic jacking off the leading edge of the lining behind the head. The TBM usually thrusts forward to the extent of its jacks, then grips the side of the tunnel and retracts the jacks to allow segment erection before jacking forward once again. The 'downtime' also allows for regular maintenance for replacing cutter heads, drilling forward exploratory holes, lubrication etc.

      The TBM also has a 'maintenance train' running on rails behind it, of up to 200m long of connected sub modules, which the head pulls along as it jacks forward. The train contains the logistics such as power packs, transformers, spoil handling, temp storage, grout pumps, spare parts, mobile workshops etc. As the lining has to be the full bore of the tunnel, it has to be broken down into sections that can pass through the centre of the train and then be re-erected behind the TBM cutting head. This erection of sections has to be carried out as close to the head as possible to minimise the length of unsupported ground behind the head for both worker safety and technical reasons i.e. the ground could collapse and trap the TBM from the sides. Add in any water issues or soft flowing ground and the erection has to carried out in a sealed/semi sealed environment as well. As a gap will also exist between the final outer surface of the lining and ground, this has to be pumped full of weak cement mix or 'grout' to fill the voids, both providing a waterproof annular surrounding for the tunnel as well as avoiding any point loads from uneven ground on the lining.

      With the TBM head (for a 8m dia tunnel) weighing around 200 tons (with a main bearing of around 30 tons) and lining segments to be handled of 1-2.5 tons ea, (maybe 8-12 segments per metre of lining) you're not playing with small numbers to shift around and construct. Appreciate that Elon's tunnels will be smaller diameter but current tunneling methods are continuously being optimized and the TBM design is matched to the predicted ground conditions, therefore there is next to no chance of increasing tunneling speeds by a factor of 10x as is quoted..

      As someone who has worked in hard rock tunnels 10,000 feet underground, where the rock was under some much pressure it was continuously 'spitting' small flakes at you, to shallow 'soft rock' tunnels where you worry about the TBM taking too much ground out and causing sinkholes to appear on surface, I have to call Elon Musk out as full of shit

      Nobody has explained yet how they turn the sleds around for a return journey.

      You either run a double decked tunnel (BTW larger diameter tunnel required than the car widths being quoted) or two tunnels with a loop or runoff tunnel arrangement with rail switching between. A fan exit arrangement multiplies the complexity by the number of exits, so is not really practical.

      Alternatively run each one way route in isolation with a double deck tunnel, with the lower deck used for empty returning sleds, which don't need as much headroom unloaded.

There's no shortage of different ways that concrete can be laid; precast segments carried in and placed is hardly the only one. I'd bet (based on no evidence whatsoever) that they're looking to cast it in place, and push off not some sort of leading edge, but an annular anchor against the hardened concrete further back (e.g. steel ring, pneumatically expanded to fill the tunnel, high traction material on the exterior)

      Did that video look like an 8m dia tunnel to you? Part of the whole point is achieving smaller tunnels with the same throughput by automated vehicles moving at high speeds. All tunneling will encounter varying problems with the geology, but the smaller diameter the tunnel, the cheaper it is.

      Appreciate that Elon's tunnels will be smaller diameter... therefore there is next to no chance of increasing tunneling speeds by a factor of 10x as is quoted..

      Diameter is not about tunneling speed. Diameter is about tunneling cost. Smaller TBM, smaller amount of material moved, smaller casing, etc, etc.

      Speed is an entirely different factor that they're trying to simultaneously improve.

      current tunneling methods are continuously being optimized

      And that's just the problem: "continuously being optimized". Boring Company, like everything else Musk has ever touched, is not about "continuous optimization". It's about breaking entirely with how things are traditionally done to achieve big leaps. The rocket industry had been "continuously optimized". Automobiles had been "continuously optimized". Etc. "Continuous optimization" is great, but you need to break "this is how things are done" paradigms every now and then.

      There's no guarantees of success in doing so, but it's very important to try. And if you try enough paradigm breaks on a given topic, at least a few will stick, even if the others don't pan out.

      Natural geology is not some nice predictable tech environment where you can confidently predict the ground conditions

      If you want your arguments to bear more weight, you need to actually argue against things that the Boring Company is actually doing. For example, argue that all else being equal, narrower tunnels are not cheaper than higher diameter tunnels. Or you need to find out what alternative approach to casing they're actually planning to use, or the approach they're planning to use to reduce cutting head downtime, and so forth and argue against *those,*, rather than insisting that "anything that's not the same as we do it now is impossible". Otherwise, you're just going to come across looking like all of the rocket and car people a decade ago.

Going by his tunnel, maybe half that, if the car elevators at each end are really quick or if he leaves his cars pre-positioned at the tunnel level. If we assume he uses the tunnel twice a week, say 100 times a year, for the next 10 years, that's 2,000 trips, or about 14,000 minutes, or about 200 hours. If he can built it at 1/20th the cost per mile of the chunnel, that would be right around $1 billion. So it's going to cost him $5 million dollars for every saved hour. Is Elon's time worth $5 million an hour? Oh, he's going to open the tunnel to general use? How many cars an hour can the elevators position? Even if you figure one car per minute, that's still a very underutilized and uneconomical tunnel!

      I think his argument is he can dig tunnels cheaper than anyone. Can he, and by how much? I don't know. I think he is mostly just fishing around for next low hanging fruit. Not a bad strategy, when you have more money than you know what to do with.

    And I don't mean rocks. Rather, it will be (underground) water. And different kinds of terrain. And seismic movements. And other tunnels (they are everywhere in modern cities). And building's basements. And on, and on.

    If he lives to basically the maximum human lifespan, for 75 more years, he will need 17 tons of food. For that time span, he'll need 23 tons of oxygen. That can be recovered via electrolysis from 26 tons of water. Alternately, it can come from 85 tons of sodium chlorate and iron powder (ingredients for oxygen candles). The water is obviously more compact (and less potentially dangerous than oxygen candles if you handle them improperly), but it requires energy input (approximately 133 KW/H or 479 mJ for a days worth of oxygen, or 5.5 kW continuously, or .038 to .075 acres of solar cells on Mars). Basically though, even without using in situ resources and without needing energy input, all the food and oxygen that he would need for the rest of his life could fit into about 102 tons. That's about $675 million worth of cargo to Mars at current spaceX launch costs. So, basically, even without any in situ resource usage or power generation, Musk could take enough supplies with him to eat and breathe for the rest of his life.
    If you allow for some in situ resource gathering, and energy generation then you could eliminate a lot of the weight. For example, you could eliminate the iron and just use the sodium chlorate and use solar heating to release oxygen, cutting about 40 tons. I think there are lithium based compounds that you could use to store even more oxygen. You could also gather materials to heat or process in various ways to extract oxygen. It turns out that there are lots of perchlorates on Mars, which isn't great news for growing crops in unprocessed soil, but leaves lots of possibilities for oxygen generation. Water is also obviously available on Mars. With processing, there's no reason that the soil couldn't be conditioned to grow crops in greenhouses. The lower general levels of insolation aren't really a problem as there are crops that grow in similar light levels on Earth, and there's no reason you couldn't boost that with grow lights or solar concentrators.
    Anyway, basically, it's absolutely ridiculous to believe that a billionaire would starve on Mars in a month, let alone a year or a decad
