The weight of a 10' diameter steel tube with 1" wall thickness is 125,000 lbf per 100 feet. Note that does not include the reinforcing braces, that is just the plate. The actual weight could be easily 2-4x greater. It also doesn't include the weight of the solar array.
My bet is that it's not significantly different to compare a light rail (subway-like) system to a hyperloop in terms of weight.
- Turing_Machine 13y agoThe weight of the track ballast alone is more than that. Gravel is about 100 pounds per cubic foot, and you need about 12 cubic feet of ballast per foot of track, or 127,500 pounds. Then you get to add the rails and ties (or concrete sleepers), plus the vastly more heavy rolling stock. The reason I said that the weight of the tube doesn't enter into it is because the tube isn't moving. The only thing that matters in terms of energy use is the rolling stock.
