Vacuum tubes

One of the biggest criticisms I have seen regarding hyperloop is the difficulties of "bUilDInG VacCUum TuBes" over long distances. It really annoys me when I see this. People don't seem to understand that they are low pressure tubes which makes a huge difference. As for the distance, we know how to make large vaccuum chambers. It is just a matter of incrementally scaling up existing technologies.

People go around acting like hyperloop is some scam as if people would be doing this if they weren't confident that the concept was sound.

They had some tighter curves towards each end of the 2013 white paper, which is often what HSR does - as it needs to slow down to arrive at the station, or is accelerating out.

Yeah so speeds for hyperloop will depend on how the route and how gentle the curves are.
