Hyperloop? I just ask myself some "minor" technical questions very "basic":
Can someone explain to me how:
1) Are you planning on taking any "small" turn to a hyperloop transport of> 10 Tonnes launched at 1200 km / h?
2) Can we compensate for the expansion of tubes hundreds of miles long?
3) Pass a propulsive magnetic field through metal tubes?
4) If tubes type "plastic", how to compensate the expansion / temperature / diameter deviations?
5) Realize seals holding such characteristics (diameter, Delta pressure, Delta T, ...)
6) Make an infrastructure "economical" Vs LGV given the mass of material needed for vacuum tubes (thickness> 30mm!)
7) Compensate for a (unavoidable) failure of levitation motors (wheels / pads holding at 1200 km / h?)
Compensate for variations in electrical production of PV panels? (hyper mega batteries powerful / polluting?)
9) Compensate ground level deviations (J / N dilation, hygrometry, rain, drought, lunar attraction, Delta T, Delta P, ...)
10) Compensate for misalignment (abutment of pillars, ground movements, settlement, expansion of supports, wind, ...)
PS: I have a little fun ... I'm just surprised the craze for a project not based on any serious scientific foundation or in-depth study, proto, demonstrator, driver, or ... !
