Even with a stationary core, I wonder how they distribute power and comm, etc.. I suppose you could have inductive coupling for the power, but those would be some pretty special transformers. Surely nothing as primitive as brushes and commutator. WiFi would get the phone and internet, but what about water and sewer? May be that part of each floor, which is an apartment, is actually in the stationary core. Go into the bathroom from your living room and come out in the kitchen because the whole house has spun around. Well no, I guess based on that assumption the kitchen would have to be stationary too.
I'll have to call a few friends and see if they have been around or in it someday.
