Turn on the Windows-It’s Getting Dark (Jan, 1958)

Turn on the Windows-It’s Getting Dark

Homes of the future may have windows that provide light at night as well as during the day. Westinghouse scientists are experimenting with a transparent phosphor placed between two sheets of glass and having an electrical conducting charge. This allows the window to be used in the customary manner, but at night electricity is turned on and the transparent phosphors emit light. The process, called electroluminescence, also can be applied to glass ceilings, coffee-table tops, murals and in various architectural designs.

    That is a really cool idea, I wonder how much voltage it uses compared to a regular lightbulb?

    We used to have electroluminescent night lights – I think my mother still has one that must be close to 45 years old and still in use. Anyway, they were about 0.02W and gave a feeble greenish blue glow – nicer than a radium glow. They didn’t turn off in daylight, just sat their using their nibbles of electricity 24/7.

    I expect you could get brighter ones by now.
