    • Very cool. If below ground is deemed to be more advantageous would Virgin Hyperloop One use The Boring Company to dig the tunnel?

      Has Elon come to the conclusion that below ground is the best way forward?

    • I feel like Elon and others have a better chance at being successful with Hyperloop than California has of getting a HSR running between SF and LA...

    • @gorudy, great questions. The Hyperloop One team did a Reddit AMA about 6 months ago and said this:

      We are definitely anticipating the need to put the tube underground. In congested urban environments there is often not another option. Tunnels have the advantage of allowing us to select more direct routes and they usually perform better in earthquakes than above-ground structures. On the negative side, they are generally more expensive and slower to construct. The choice depends on the route and the urban landscape! -BK

      They also had a post on their website about living in the golden age of tunneling. The thing is, the world's longest tunnels top out about 35 miles and take 20 years to build. It feels like the power of hyperloops is for long-range travel fast, so it seems impossible with current technology and cost constraints to put the whole hyperloop underground.

    • I think it'd first make sense to use a hyper loop for the transportation of small packages but then for larger loads including people. Tunnelling is certainly a challenge for underground road systems, not to mention a hyperloop, but Musk thinks the technology can be improved by a considerable amount.

      As someone who has worked for years in the heavy equipment and construction industry I'd also say we could consider shallow underground tunnels similar to what we do with pipelines. That'd have several advantages that above ground and well below ground doesn't have.

      North American has no high speed transit systems and we're in the dark ages compared to other areas of the world. To have a hyper loop transportation system would be to leapfrog a generational level of technology.

    • How long was Bertha stuck in Seattle?

      Also below ground in urban areas is often more congested than above. There are subways, sewage, water, telecommunications, Jimmy Hoffa, steam in New York City, pilings for buildings...

      There is a readon the tunnels were built at Disney World before the buildings

    • Only in larger cities with more underground infrastructure. Even then, stations could be located adjacent to existing subway stations for access to the surface.

    • Oh. And a larger question or two. Do you build stations where there are no cities (or very small cities) in the hopes of easing congestion by moving populations away? And what about emergency access? By conventional travel, help will often be a long time coming.

    • I hadn’t heard much on Elon’s Hyperloop project.

      And then this:

      “On Thursday, the Tesla and SpaceX CEO explained his plan for a fifth hyperloop design competition. These events, held at the SpaceX campus in Hawthorne, California, pit teams against each other to design the best pod for the transit system. The first four events were held using a 0.8-mile-long, 72-inches-wide straight test tube with no curves. 

      “Musk wrote on Twitter that the fifth competition will tweak this setup to better reflect real-world conditions, while also providing a longer track. Hyperloop teams have previously said that longer tracks are crucial to reaching the potential top speeds.”

    • Countries need some new and exciting big projects to stimulate the economy and give people hope. Maybe this will be one of them. Maybe Covid-19 could actually push it closer to reality. One can only hope something big and exciting comes along.

    • Off-topic. No worries if you don’t want to answer:

      I know you are a teacher in Canada. Do you know what teaching is going to look like in the fall as far as remote or in-person learning?

      When does your fall-term start?

    • Our school for kids starts in September here. The first thing is we have to ha e our covid numbers reasonably low before they open up. So far it’s been good but we might be currently experiencing a second wave. The schools are deferring to our provinces health minister guidelines and they keep saying we are following the science. We will see if that holds up. Kids will stick with one group all day. Teachers will rotate to different classrooms. Kids will disinfect inside the entrance of the school and before entering each classroom regardless of why they left. No fountains will be allowed. No fabrics in the classrooms. No carpets or tapestries. Extra cleaners hired for schools to wipe stuff down. No cafeterias. on buses will sit with family members as much as possible. Physical distance in classrooms as much as possible. Smaller class sizes where possible. Hmm... mask wearing for kids... uh... might ha e some physical barriers but haven’t had any confirmation on that yet. Also we will likely be teaching in the classroom and online at the same time. That part will be an overload and overworked nightmare. That’s all I know so far. The option of half week rotations for smaller class sizes was talked about and an option if we have higher covid rates. It it gets really bad we will go back to online. The union is trying to pressure the board to ha e better sub coverage and figure out what to do for families who don’t ha e money to keep kids at home. Time will tell.
