I’m more interested in the magic transparent insulation. Warm enough to sunbathe on one side, cold enough for snow on the other side, and no melting? Not only that, but it appears to be paper thin and extremely light because it’s supported by thin metal tubes.

Sure, with massive amounts of electrical heating you could make a heated plastic dome. But, you’d also melt all the snow nearby. There would be little rivers of melted water all around.

This dome is basically a perfect greenhouse, and is way beyond what we can currently achieve with cold-weather greenhouse technology.
