“RT @TheCaptainEli: Did you know? Elon Musk’s first public mention of tunnels solving urban traffic was in a Jan 26, 2016 Hong Kong intervie…”

“@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”

“@RenataKonkoly @bipulh We need to finish building a much longer vacuum tunnel for speed tests & probably have an additional competition for tunneling itself”

“RT @HSajwanization: “Dubai Loop” 🇦🇪 with Elon Musk 🔥🔥✨ … we are very proud of this partnership !!”

“@shaunmmaguire Exceptionally hard engineering problem. Also, this will be used to make Hyperloop a reality in the future.”

“Good Hyperloop feedback from Ansys. Am excited by how much it can be improved by open src contributions! http://t.co/bD0u3roBd0 http://nbcnews.com/technology/hyperloop-sounds-crazy-simulation-says-it-just-might-work-4B11202787”

“@RenataKonkoly @bipulh Aiming for 10km with lots of turns to better approximate a real-world tunnel”

“RT @rta_dubai: The implementation of the first phase of Dubai Loop project will commence with the construction of a 6.4km pilot route, comp…”

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

“@FischerKing64 Living in sheltered communities breaks their feedback loop to reality”

“@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)”

“@BrianRoemmele Tunnels ftw”

“@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.”

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

“@DirkSmit76 Two tunnels about a mile long each”

“@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.”

“RT @DOGEai_tx: @MarioNawfal The census loophole is a sovereignty issue, not just a math problem. Sanctuary states gaming the system by coun…”

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

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

“@mariom An underground Hyperloop would mean no disruption above ground and be way faster, so I think it is he right way to go”

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

“RT @Rothmus: >tap >tap again >tap tap tap tap >this should be Sidney Sweeney @LoopitAi https://t.co/qkOLIFipoa”

“@DJSnM They will, but the hydraulic system is closed loop, so no fluid lost. They do need more power & energy, but rocket has plenty of that.”

“Will publish something on the Hyperloop in about four weeks. Will forgo patents on the idea and just open source it. Not a vac tunnel btw.”

“@SmallPettingZoo That was fun! I think we did that around 1am or so. Might get carpal tunnel from so much dungeon grinding, but worth it 🤣”

“@OfficeOfOMAR @HyperloopOne I hope they and any others trying to advance transport technology succeed”

“@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.”

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

“First flight of 10 story tall Grasshopper rocket using closed loop thrust vector & throttle control http://t.co/NH24BQMH http://yfrog.us/f362mloybjbosdefkdeoytqsz”

“@CalebH92 There is an actual tunnel and it's getting longer every day”

“@dnathe4th @DJSnM We used to have a (lame) open loop hydraulic system, but that was upgraded to closed about 2 years ago”

“@FredericLambert A Loop is like a Hyperloop, but without drawing a vacuum inside the tube. Don’t need to get rid of air friction for short routes.”

“@SeeDecentral @technology I'm not coming for anything. Just digging some tunnels and might draw a vacuum on some of them.”

“@_andyoneal @patriciapaje That's just to win our Hyperloop student competition in ~1 mile tube. Practical version would have a turbo compressor on front taking ram air pressure at near sonic to hypersonic speeds & driving that thru air skiis & rearward for thrust.”

“@trabru Yup, machine arrives next month and we start digging the tunnel!”

“@SmileSimplify @beboutside @Hyperloop @SpaceX @paradigm_hype @swissloop The latter. There are pretty long gaps between each team run, so livestream is not the way to go.”

“@FormulaSAE Contact Steve Davis at Hyperloop@spacex.com”

“@LooperNor Yes, this will, if all goes well, be the first commercial spaceship to dock with the Space Station. T zero ~ end of April.”

“@RobertGaristo V much agree. Moreover, there is risk of severe non-linearities in feedback loops causing sudden warming.”
