I Have seen numerous glass skyscrappers with men dangling on the outsides cleaning the glass every few weeks....my idea is to have a fitted wiper (like in a car) which can be activated whenever the glass needs cleaning. the process will start with water flowing from the top of the building, followed by a coat of soap and then the wiper runs scross the building top to bottom....imagine the sight of a 100 storey building giving itself a cleen... wont that be a spectacle.
