The focus from people on bathrooms is puzzling to me. I've been on buses, without facilities, that go for hours without stopping. This is a 35 minute ride with restricted movement, if you greatly fear being able to hold it for that long, there are other, less efficient methods of transport to accommodate you.
Yeah. Adult diapers! Problem solved.
I'm not saying that Hyperloop is an inherently flawed project or that HSR is the perfect solution to the state's long-haul transportation needs. I just think that Musk is oversimplifying the situation.
I worry that the necessary straightness of the tube will be difficult to achieve. The pads float 0.5 to 1.3 mm from the inside of the tube, so deviations from straightness on that scale will cause the pads to crash. Any contact at 760 mph would probably damage the pad, plugging the air holes.

You're thinking city buses. I'm thinking long-haul busses (like greyhound in the US). Greyhound buses likely have facilities, what I'm actually talking about are the buses used a core parts of the transportation infrastructure all over South America. Many of these also have facilities but I've been on many where the bathroom isn't functioning or just plain isn't there. You can easily travel for 30 minutes to an hour…
All these buses analogy isn't exactly the same because they still have the option to stop somewhere, which give the passengers the assurance that if they can't hold it's not the end of the world. Taking that into consideration, I think it could solve most people's bathroom concern by adding bathroom stops to the loop, in the case of semi-emergency, ideally a pod should be able to make a stop upon request within 5-10…

He doesn't properly address thermal expansion of the entire system. A long straight steel tube from SF to LA will expand a total of 300 meters over a 40C temperature change. Where does it go?
Claustrophobes will not be eager to travel in this fashion.
Then use http://www.bbc.com/future/story/20130812-planes-that-can-pic... . Compared to that, this Hyperloop idea is best described as "No pilot. Less space than a 747", by teenage boys. On the other, more important hand, at firt view, this looks feasible to me (taking into account who published it) I do wonder about the "little noise" claim, though. That fan a few meters in front of you that compresses air so that yo…

If I read it right, the movement is absorbed by shock absorbers that need to be installed for earthquake protection anyways. You just need to make sure that the segment between the lateral movement/shock absorbers are sized such that the differential thermal expansion doesn't violate the deflection requirements.

What will probably happen is that you get a transparent car and advertisements on the inside of the tube.
That fly past a metre from your face at 1,000 km/h!
