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

Well the pod has compressor - so it literally can hit the fan :)

The only thing I really dislike so far is the battery pack in the pod. I would have wanted to see something more elegant instead. And this way we halve the weight of the pod.

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

> 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 bowl?).

Some interesting tidbits:

    The total trip time is approximately half an hour, with capsules 
    departing as often as every 30 seconds from each terminal and carrying 28
    people each. This gives a total of 7.4 million people each way that can be 
    transported each year on Hyperloop. The total cost of Hyperloop in this 
    analysis is under $6 billion USD. Amortizing this capital cost over 20 years and 
    adding daily operational costs gives a total of about $20 USD (in current year 
    dollars) plus operating costs per one-way ticket on the passenger Hyperloop.

    For aerodynamic efficiency, the velocity of a capsule in the Hyperloop is 
    - typically: 300 mph (480 kph) where local geography necessitates a tube bend radii 
       3.0
    miles (4.8 km) or where local geography permits a straight tube.

Each chair is actually a toilet. Problem solved.

I think he should start a ticket pre-sale on kickstarter and see if he can be the first person to reach $6 billion for a project.

From my skimming of the PDF, it sounds like a pneumatic tube transportation system with a compressor fan on the front of the vehicle that moves high-pressure air from the front to the back maintaining a low-pressure state around the vehicle. Kind of like an Earth-bound Alcubierre drive.

The pumped air is also used to create an air cushion around the pod to keep it suspended at high speeds. Also, solar panels line the top of the tube so that it is self powering.

If this is going to be running above ground, how do they purpose to find space to even build this?

My only guess would be to build it vertically. . which is were everything is going anyways, right?

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...

it's a 35 min commute so those things are not necessarily required. Amenities can be built outside the boarding station
