    Boo. All I want is fast as fuck transport. I don’t see why maglev trains in a vacuum are so difficult

      😂 That’s what Muskrat wanted you to believe. Engineers and people with more than 2 brain cells have debunked the Hyperloop idea for years. Here’s one of them from 7 years ago.

        And even before that the Swiss seriously studied the possiblity and gave up.

          The vacuum is the hard part, not the maglev. You would need to enclose the entire track inside if a vacuum, and that world be ridiculously expensive and practically impossible with current technology. It’s already very expensive to build a tunnel for a train, which is why they are avoided if possible. But this would need to be all tunnel that is air tight, so even more expensive than regular train tunnels.

          To put it into perspective, the current largest manmade vacuum chamber is at a NASA research facility in Ohio. It’s a cylinder with a diameter of 100 feet and a height of 122 feet. If this were laid on its side, about 1.5 New York subway cars could fit inside. The largest vacuum ever made can barely fit the vehicle inside, let alone allow it to travel between two different places where the extra speeds would be warranted.

            That kinda puts it in perspective. What about particular vaccum? Or just where the tracks meet the train. That’s the only bit with drag ?

      Because maintaining a train length vacuum is really difficult and doesn’t really provide that big of a benefit.

      Atmospheric rail has been attempted with varying degrees of success (but never to a ‘replaces traditional rail’ degree) for 200 years.

      Thunderf00t has many videos on the subject. I recommend checking them out. He’s been calling out musk’s bullshit for years, and is right every time.

        Read the rest of their posts. It doesn’t seem like they’re being sarcastic.
