>"Windows need be no more than an archaic touch, and even when present will be polarized to block out the harsh sunlight. The degree of opacity of the glass may even be made to alter automatically in accordance with the intensity of the light falling upon it."
This actually makes me curious. Why don't we have photochromic windows? We use the technology in transition lenses.
A relatively cheap alternative is taking 2 polarized pieces of glass and making them rotate one on top of the other - that way the amount of light they let through is variable. The main drawback is that it requires circular windows with mechanical rotors.
