Shouldn't this be a solved problem by NASA?
Space shuttles would have similar challenge (actually in reverse) - how to protect sealed air inside a closed cylinder from almost absolute vacuum outside in an environment where heat and cold are extreme; the cylinder being fabricated from overlapping conjoined pieces.
- thearn4 10y agoSome folks at NASA have spent some time analyzing the principles and technical challenges behind hyperloop (I know most of them for what it's worth): https://scholar.google.com/scholar?cluster=4581830088403547634&hl=en&as_sdt=0,36&sciodt=0,36 https://scholar.google.com/scholar?cluster=45818300884035476...
- achow 10y agoThanks for sharing. They seem to be convinced about the viability albeit concluding that it may need bigger diameter pipes and the speed would be little slower. No alarms on thermal expansion, structural integrity etc.
- thearn4 10y agoyeah, the analysis at that stage was focused more on the propulsion aspects of the system.
