No toilet, and no way to get off, or even really stand up? I know some personal jets lack such facilities, but they're not exactly open to the public. At least on BART you can move away from the crazy...

No toilets on commuter buses either and people ride them 45minutes to 1+ hours everyday with no issues. You're stuck in the "long trip" "it's like a train" framework. It is neither.

Commuter buses stop regularly.

That capsule ( http://images.bwbx.io/cms/2013-08-12/0812_Hyperloop_605.jpg ) looks like a claustrophobic's nightmare. Otherwise very, very cool.

Doesn't look any more cramped than the back seat of a car.

> 4.5.6. Human Related Incidents Hyperloop would feature the same high level of security used at airports. However, the regular departure of Hyperloop capsules would result in a steadier and faster flow of passengers through security screening compared to airports. Ugh. That only seems feasible if back-scatter scanners are the only option (but would you still have to take your belt off and put all metal in a little b…

I can't wait to get frisked by one of Musk's minions!

LA -> SF in 30 minutes. Why would you need a toilet?

Unless it breaks down. In which case the "toilet" question might become quite pressing, quite quickly.

The key advantages of a tube vs. a railway track are that it can be built above the ground on pylons and it can be built in prefabricated sections that are dropped in place and joined with an orbital seam welder. Did anyone else read this and imagine laser beams fired by satellites?

Not really. It's a valid welding http://en.wikipedia.org/wiki/Orbital_welding ), but I imagine it might be quite a task to scale it up to pipes as large as would be needed for this project.

Orbital welders can be used in pipes on any size (smaller sizes often need special welders). Not sure what the record is but they are commonly used on water pipes that are several meters in diameter. Should work fine for the Hyperloop tube. Seems like all the required technology is proven but I'm sure we will hear more from all the experts in the various fields.

I honestly expected better work. I feel like this is something everyday users on Reddit or HN could have put together in a report. I only gave it a look because Elon Musk's name is on it. That says something sad about me when it comes to the Big Imagination projects :-/

what happens when you develop unexpected gastric issues mid-30 minute journey?

What happens currently on a high-speed rail system? I suppose there's a lavatory in the HSR (e.g.: France's TGV).

I was thinking that a well-timed explosive charge on a support pylon would make for a nice mess, but I suppose it's not any easier to secure a conventional railway.

Currently you get up and go to the bathroom at the end of the car.

I've only had time to skim the full PDF, but there's something about experiencing 0.5g of acceleration - unsure if that is a constant or if that is simply right at the very beginning.

If you're going to experience 0.5g of acceleration over a prolonged period, letting passengers get up and move about is going to be a bad idea. It also doesn't look like there's enough roof to get about in that capsule. 0.5g doesn't sound like a lot until you think about it as 50% of your body weight tacked on, in a direction you're not used to having it tacked on. Pretty simple in a seat, much less simple trying to walk.

Does it support multiple pods in the tube at once?

Yes, but no discussion of how you'd bring the system down if one broke down mid-trip or how you'd bring it back up. The individual cars only carry power to maintain speed, no to accelerate, so if they have to stop because something goes wrong, a whole bunch of people are stuck in the middle of nowhere without a toilet (or air?)

I stand corrected. In fact it comes down to two paragraphs and doesn't really cover much including, for example, just how long this would take (the cars behind the stalled vehicle would use emergency brakes then proceed at low speed on wheels to the nearest station -- sounds like at least half a day of down time).
