So his point about spacing may be true for loading and unloading, but it is not for emergency stops. You can exceed .5g's in am emergency. With appropriate rest

So his point about spacing may be true for loading and unloading, but it is not for emergency stops. You can exceed .5g's in am emergency. With appropriate restraints, 4 or 5g's would be possible.
The larger problem is: if you can build a hyper loop track at 10% of the cost, you can build an ultra light conventional "train" on the same pylons and with lighter weight,cheaper, track. It would run at maybe 200 or 250pm and hence with reduced capacity. At best Musk's cost claims are a capacity/cost trade off. At worst, they are suspect. I think they are suspect, especially given the extreme tolerances of the tube
- johntb86 13y agoI think one advantage of the hyperloop is that it would probably be quieter (they claim the compressor uses <150 HP) so that would make putting it on a pylon simpler and would reduce the need for noise barriers. Also the separation between tubes could be much lower than the separation between tracks. I'm not sure how much this would affect the feasibility of putting a more normal HSR train on small, lightweight pylons, but it wouldn't help.
- anologwintermut 13y agoI mean his tunnel/tube is more expensive than a noise barrier. It has all the same properties but has to withstand far higher pressure differences and be built to insane tolerances.
- johntb86 13y agoAlso, it has a large enough speed advantage that it doesn't have to go straight to the city center to have a time advantage over air travel, and that would be a big part of reducing the cost while keeping it viable.
