On top of that, the first few images show signs of significant moire.
now that I think of it...these pics look familiar too

I'm not seeing it.  I guess I'll have to take a road trip one of these days.

I sure hope this guy doesn't want electrical wiring or plumbing in those walls.

I would guess that it is similar to block construction also.  I am wondering how they get vertical rebar in there as it is code in this state.  That is unless you have some structural testing to prove it isn't needed.  Being in the middle of building my third home and doing most of it myself makes this very intriguing.  Plumbing and conduit could also be run in the middle with a little drilling also.

Looks like he's printing two walls concentric with a gap - if it was me I'd look into strapping the wiring in conduit to rebar, and dropping that into the wall cavity, tying up the cable ends and then filling the whole lot with more concrete...

Interesting out of the box concept. I see this as a proof of concept build to get the public attention. I expect they will soon try an actual building with conduit foam insulation in the walls or concrete fill in the walls.
Poured cthe idea of poured concrete houses has been around for a long time IIRC one of Thomas Edison's inventions but one that never took of.
