.................I think plumbing and electrical would be a pretty big problem.....................
Great point!
I guess you could pick up power from the rails it moves on, but fresh and waste water would be a real problem.
I wonder if this could be built to any existing code in the US?
no doubt.
However, it appears as if the central core of the house doesn't move and everything pivots around it. That is probably where the plumbing/electrical kitchen/bathrooms would have to be located.
