“@benedictevans @parthsheth 155mph is common on the Autobahn. Even with only 5 offramp tunnels, exit speed drops to 31mph.”

“@benedictevans @parthsheth Avg speed of NY Subway is actually 17mph. TBC loop can run at 155mph with 16 pax autopods passing every second, routing automatically between tunnels to their destination. That’s 57,600/hour/lane & you can build dozens of lanes. Will crush any subway in throughput & convenience.”

“Another great thing about many layers of interconnected tunnels with ramps & elevators is that they can go from near your home all way to popping up at destination parking lot”

“@quayran Opposite is true: you can have 100’s of layers of tunnels, but only one layer on surface (to first approximation), therefore trains should be on surface, cars below”

“@justpaulinelol Yes. No one will forced to take the tunnel. It’s optional!”

“Boring Company guide to why tunnels are awesome & safest place to be in an earthquake https://t.co/ZZIPQlscw1 http://boringcompany.com/faq”

“Fundamental advantage of layers of tunnels is you can have as many lanes as you want going in any direction. Will feel like folding space from one part of a city to another.”

“Racing at 127mph in a tunnel under LA”

“@DirkSmit76 Two tunnels about a mile long each”

“Boring Company starts digging Vegas tunnel in 2 months. Aiming to finish by end of year.”

“@Model3DLR @mortchad @EV_Stevee @Tesla We’re closing the loop on Autobahn driving. Will improve dramatically in coming months. Ultra gemütlich.”

“@westcoastbill Sensors are for the weak. Just go open loop.”

“@CopticChad @Erdayastronaut @privater @marc_benton @Teslatunity @Model3Owners @Tesla Net power to warm pack is especially low when motors are running, as coolant loop routes motor heat to the pack when outside is cold (& rejects motor heat to air when outside is warm)”

“@annerajb @flcnhvy @DrivingSlate @TeslaParaTodos @JenniferSensiba @cleantechnica @28delayslater Maybe active in a month or so. Focus right now is getting to high speed, tight follow distance in test tunnel.”

“@techreview Director of CERN asked me about Boring Co building the new LHC tunnel when we were at the @royalsociety. Would probably save several billon Euros.”

“@enn_nafnlaus @TheJewbyrd7777 @DrakeFerroNyalk @13ericralph31 Spiral-winding is great for uniform thickness. We used that for the Hyperloop vacuum tunnel. However, Starship skin thickness will vary considerably according to loads.”

“@nichegamer @boringcompany So long as the tunnels are spaced about one diameter apart, most of the stress will flow around them, but this won’t matter for the first few layers”

“Perhaps lost in the transport debate is that @boringcompany built a 6000 ft tunnel in LA for ~$10M with V1 (Godot). Next tunnel will be made with V2 (Line-Storm). V3 (Prufrock), aspirationally 10X better, should be operational next year.

“Are tunnels safe in an earthquake? https://t.co/vxcZ2Hi2qx”

“@ElSchumi @FredericLambert @boringcompany Passive lateral safety is required by regulators & I think they’re right. Might be able to build this into the tunnel wall though. So long as the vehicle is prevented by physics from rolling or jackknifing, there is probably a good safety argument.”

“@realkrauswife I know that area well. Best would be to add ramps into the tunnel system from the basement levels of the parking lots surrounding 3rd St.”

“Next step for @BoringCompany Loop is demonstrating high throughput at high speed. Target is 4000 vehicles/hour at 155mph (250km/h).”

“The demo ride takes you in *same* car on road, down elevator, zips through tunnel using guide wheels, up elevator at destination & then drives on normal roads back to start”

“All Boring Loops will include continuously circulating cars dedicated to pedestrians & cyclists”

“Tesla in @boringcompany tunnel with retractable wheel gear that turns a car into a rail-guided train & back again https://t.co/3a6i0NoSmi”

“Boring Company product launch on Dec 18. More than a tunnel opening. Will include modded but fully road legal autonomous transport cars & ground to tunnel car elevators.”

“@rainnwilson Your Tesla can function as a boat for brief periods of time https://t.co/FONhnIiv8j https://electrek.co/2016/06/18/tesla-model-s-driving-swimming-flooded-tunnel-video/”

“@highspeeddoc @boringcompany We’re doing an EIR for the greater LA tunnel network. Thought we might need a N-S test tunnel (hence Sepulveda proposal), but we’re just going to do rock core samples along that corridor instead.”

“@NBCNews This is completely backwards. Based on what we’ve learned from the Hawthorne test tunnel, we’re moving forward with a much larger tunnel network under LA. Won’t need a second test tunnel under Sepulveda.”

“Congratulations @BoringCompany on completing the LA/Hawthorne tunnel! Cutting edge technology! https://t.co/80WbSQekCQ”

“Boring Company just broke through the other side!! https://t.co/4yxQgpPVfZ https://m.soundcloud.com/fish-tales/fisher-losing-it”

“@TheAndwee Watchtower (feat. knight) will be at LA/Hawthorne tunnel entrance”

“The Boring Company is building a watchtower in LA out of dirt bricks & we need a knight to yell insults at people in a French accent https://t.co/VChOVXXVaz https://www.boringcompany.com/jobs/”

“@Benioff @boringcompany LA/Hawthorne demonstration tunnel activates Dec 10. Runs parallel to 105 freeway from Crenshaw Blvd to 405.”

“Walked full length of Boring Co tunnel under LA tonight. Disturbingly long. On track for opening party Dec 10. Will be very one-dimensional.”

“@nextspaceflight @Erdayastronaut This is a ~ 6000 ft demo tunnel. First operational, high-speed tunnel still set for Chicago, pending regulatory approvals.”

“The first tunnel is almost done”

“This time, the vacuum tunnel will be a bit longer & SpaceX will provide some advance funding for student teams with most promising designs. Bonus award for all race pods that exceed half the speed of sound!”

“@Hyperloop @SpaceX Congratulations to all teams in the student @Hyperloop competition! To make high-speed pods that can operate in vacuum is very difficult. Was great to meet everyone!”

“@JamesWorldSpace Maybe worth trying: insert a 1m diameter nylon tube (or shorter set of tubes for most difficult sections) through cave network & inflate with air like a bouncy castle. Should create an air tunnel underwater against cave roof & auto-conform to odd shapes like the 70cm hole.”

“@jacobinmag Btw, if anyone else wants to build this tunnel, please do so. It’s a lot of work.”

“@FrankIppolito @boringcompany We don’t think our product will be the cause of any wildfires, but The Boring Company is donating $10k.”

“@SPPhotonic Each flamethrower comes with a state-of-the-art The Boring Company brand fire extinguisher. Will offer a TBC ice blaster before the dry season starts in winter.”

“First 1000 Boring Company Flamethrowers being picked up today! https://t.co/hBMp5fGzAB”

“@prakash_d @grillick @IndianInterest “Pneumatic” means propelled by air. Opposite of Hyperloop.”

“@IndianInterest Actually, Hyperloop draws a near vacuum in tube & each pod is powered w electric motors. It is opposite of pneumatically powered.”

“But The Boring Company is right behind you at 1/15th your speed & soon will be 1/10th! Start sweating …”

“Will be presenting & taking questions about The Boring Company plans for Los Angeles at 7pm on Thursday”

“Boring Company Hyperloop will take you from city center under ground & ocean to spaceport in 10 to 15 mins https://t.co/VhpfhgdXSd https://x.com/tedtalks/status/988501449586987008”

“@nextspaceflight A cool thing about the design is that’s easy to incorporate branch loops to serve small to mid size cities without slowing down the main loop at all”
