So... what do you do as you exit the elontube? Do you stop the car, open the door, and then take off the little helper wheels and put them in your trunk?

Why don't companies reuse tunnel boring machines? I'm kinda astonished that its cheaper to keep building new ones instead of even taking like the engine and other expensive parts out of abandoned ones. For instance, apparently, if the New York 2nd Avenue Subway didn't get enough funding to do the whole line in one continuous stretch they would've shoved the borer they'd been using to the side when one part was done and bring in an entirely new one for the next instead of reusing it.

So I guess the Proof of Concept is that Elon can spend more money digging a tunnel using the exact same machine at a shallower depth and easier ground than an existing tunneling contractor.

This reminds me of that solar road project that seems really cool until you realize that a lot of road traffic isn't your Honda Civic and has poo poo like gravel or god forbid studded tires and the panels would get beat to poo poo within a week. People with good intentions who have no loving clue what life is like outside of their very narrow experience.

So I haven't been following the dumb tunnel thing too closely, are they still planning on depressurizing the tunnels? And if so are tesla's even designed to withstand a 1 atm pressure difference? Because from what we've seen of their integrity so far I'm pretty sure the windows are gonna pop out.

this loving poo poo was bothering me enough to spool up Wolfram Alpha again; so, the tunnel traffic goes 150mph Musk's brainstrong idea for merging is; split off ramps/branches you accelerate on now, I can't be bothered to look further, but this https://fastestlaps.com/tests/ar2gue72uzk3 gives Model S P85D (faster than any model 3 I think?) best 0-150mph of about 30 seconds that gives average acceleration of about 2.235 meters per second, per second travelling at that acceleration for 30 seconds to reach the 150mph you need to not obliterate yourself and the rest of the tunnel traffic takes you a little more than a kilometer of a run each of these on-ramps has to be another extra kilometer of a parallel tunnel seriously they need to lock this lunatic up

also it’s just one way so far...so if you want to go back to your destination traffic would have to loop around connected track or Elon would have to design a complicated set of on and off ramps to two different directional tunnels will there be different ramps going in different directions once you get off/on your personal car elevator? how the hell would that work? and if you take the wrong one you’ll get smashed into a flaming pile of debris that will stop of traffic and kill everyone in the tunnel this is my favorite dumb poo poo idea he has had yet. the more you think about it the worse it seems

Megillah Gorilla posted:Speaking of, I'm still stunned over that concrete. hey I can actually answer this! I worked on the Indianapolis Deep Rock Tunnel network for a few years. it’s a 300 some feet deep 18 foot diameter tunnel for combined sewer and it’s lined in concrete. Concrete mixes all have an air % specification generally in the 4-6% range. For these tunnels, concrete needs to be pumped down. The concrete loses a ton of air going through the pump so you need to have your mix account for it so that it reaches the delivery point with the right amount of air. it’s generally a pain in the rear end and you need to test throughout the day to make sure nothing of getting hosed up. my guess is they didn’t bother with testing or worse, tested at the point where the concrete is obviously going to pass. also here’s a photo of what the Indy tunnel looks like prior to concrete lining.

I bet they did disassemble and extract as much of the supporting equipment as they could though, no reason to leave valuable metal behind.

Thanks for this. Just looking at the Muskcrete I knew there was something horribly wrong with it. I've never in my life seen concrete - fresh concrete - with so many patches. It must have started falling apart immediately. People forget (or never learn) that setting concrete is a chemical process, not a physical one. lovely aggregate, not enough air. Add in vehicles travelling along it and I wonder how long it's going to take before it crumbles and sends a test car careening through the tunnel to land on its roof.
