Hyperloop unveils full-scale 750-mph passenger capsule

A capsule is irrelevant. To get to 750mph they actually have to get a track that can mitigate all known and unknown physical problems that stop trains nowadays from even going over 350km/h during operation. Showing a mockup does nothing to address hyperloop's baseless promises and simpsons monorail reenactment. To put it in perspective, its as if they showed a supersonic jet when they didn't even recognized the existence of sonic booms.

That looks streamlined. I thought the idea of the hyperloop was that it was low vacuum and the front of it was a giant fan to move the remaining air from front to back of the capsule to further reduce friction. Or was that only in the early design and it's been abandoned?
