The following submission statement was provided by /u/mancinedinburgh:

Windows as modems? Swiss scientists recently announced they had created windows that convert sunlight directly into electricity. This seems to be in a similar vein, whereby polarisation of sunlight is converted into binary code used to send signals to devices in a particular room. Goodbye router boxes? Perhaps. It sounds cool though to me that wireless Internet could be provided to entire offices or homes through adapted glass windows.
