I vaguely recall a few weeks back hearing on the ABC newsradio of a town in Europe (Germany???) I think, where the street lights at night are turned off and if someone wants to go for a walk or something at night then to overcome safety problems they can activate the streetlights for the streets they want to use for a period of say 20mins by using their mobile phone and pressing certain codes into the electricity grid to activate. I thought it sounded like a great idea. After all how many people go for walks late at night? Sorry I can't recall anymore of the details but obviously the technology exists.
