> This is not a dome.

Thanks for the correction, I read the page without enabling JS on it, so the images didn't load, and every previous iteration of this technology I've seen has been limited to producing domes or arches. Nonetheless, even if you could, in practice, stack multiple floors using this new form, no developed country with any potential seismic activity or hurricane/typhoon threat will let you build multi-story structures like this (or perhaps even single-story ones), and I think you're right to use the word "magic" about using rebar with this, since installing rebar is a very labor intensive process, thus negating the only alleged benefit of this technique.
