A modest low pressure in the tube would become high pressure in the tube when you start pushing a piston (Hyperloop car/capsule) down the tube. Where would all the air piling up in front go? This is why the original concept drawings had large fans on the front of the cars, however this concept seems to have been abandoned, leaving this problem unsolved.
- nickik 6y agoThe capsule pumps the air behind itself. That is correct. However this is is Virgin Hyperloop. Its very different from Elon Musk Hyperloop design. No evidence that Elon Musk changed his design. We know he is still on his back burner. His change seems to be more about moving to tunnels rather then tubes.
- carabiner 6y agoThe air flows around the train, same as a subway. The low-pressure tube still maintains an lower net pressure and corresponding reduction in a drag vs. a tunnel with standard temperature and pressure, even if there are variations in static pressure along the length of the tube.
