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.
