What's even funnier is that they'll need to have the entire facility held at vacuum. You can't have the lever arm of your centrifuge going around at some fraction of 2 km/s with air in the way. Having a volume so large held at vacuum? Laughable. Absolutely laughable. Especially with so many moving parts inside. So then, when the payload comes out and hits air, your picture happens, essentially an explosion, which is then sucked back into your launch system, since it's sitting at a lower pressure. I wish them the best of luck with a design that inevitably leads to a series of valves, which, unless everything always goes absolutely perfectly, leads to complete destruction of the entire facility.
