Micro Reactor Systems Creates Frank Herbert's Polawindows
In his 1972 novel The Godmakers, Frank Herbert wrote about special windows that could be clear or opaque with the touch of a button:
Orne returned to his room to change for dinner, stopped at the polawindow, which he tuned to clear transmission. The quick darkness of these latitudes had pulled an ebony blanket over the landscape. Distant cityglow painted a short yellow horizon off to the left. An orange halo remained on the peaks where Marak's three moons would rise.

It appears that these windows are ready to go. According to Nikkei, electronic curtains just 0.4 millimeter thick uses liquid crystals to opaque the otherwise clear plastic sheet. When you want to see out the window, flip the switch and the Micro Reactor System curtains become as clear as glass - just like a polawindow.
A typical office window would use only a few pennies per month in electricity.
