I took a screenshot of the pod from the video from Sigmetnow's link for the Dubai - Abu Dhabi line. I must say I think they did a good job there.
The pod looks great, and it has an isle, and 4 seats sideways, and possibly even a toilet. That takes care of one of the items on my list.
Couple of things :
First thing to notice is the doors. They are indeed "airplane" style doors as I expected for a pressure tight vehicle. Not the unreal Tesla-like "fold-up" doors they showed in the earlier presentations.
Secondly, this pod does not have Elon's compressor in front, so I guess they are going to "muscle" their way through the Kantrowitz limit, by mounting more linear motors in the track.
Thirdly, look how tightly the pod fits in the tube. If that tube is representative of the real tube size, then the fraction of Atube/Apod is going to be much lower than our previous assumptions and the tests they did in Nevada (which came in about Atube/Apod=2). This one shows Atube/Apod around 1.1. That means the Kantrowitz limit will be reached much sooner than Mach 0.5.
Essentially what they show here is a pod in a tube that will push ALL the air forward for the speed it is designed for. That means the air pressure on the track will double every time the distance to the end station is halved. Like a piston. That certainly creates a pressure wave that will slow the pod down to a crawl near the end station, and create quite a bit of heat and also noise at the end of the tube as the air pressure in front of the pod increases exponentially and rushes around the pod.
That last one is quite interesting. Maybe they want to use that air dome as a brake...?
Come to think of it, if they mount the air pumps near the end of the tube, they can use the air pressure wave that the pod creates as an opportunity to suck out more air.
That would be a clever way to get around the Kantrowitz limit,....
