Windows powered by Windows?

Excuse me while I just plug my PC into the window ....... so I can, errrrm ........, charge it up.

Sounds completely crazy? Well it isn't going to be, as this from GizMag reports. Nihon Telecommunications have developed a method of embedding lower efficiency photovoltaic cells into window panes, which on a good sunny day can "generate up to 70 watts of electricity per square meter of glass."

Shame that it will only work via a USB power port.
