Authors: German inventor Dieter Grote has come up with an interesting energy saving idea that involves switching off street lights to save power until they are actually needed. He's not plunging the German village of Morgenröthe-Rautenkranz into darkness however, since the system, called Dial4Light, allows pedestrians to switch the lights on using their mobile phone.A phone needs to be registered with the service before it'll work but then the user can dial a central number and pick an access code for the street they want illuminated, with codes stored in a browsable database on or the lamps themselves. There are no charges involved aside from the phone call itself, and trials have shown savings of 25% on consumption. Obviously there's plenty to do before such a system can be effectively integrated on a wider scale, but finding a way not to waste power on lighting that isn't needed when there's nobody around does seem like a positive step forwards. Check out the BBC report from the link below for more details.- Paul Lester [BBC] mobile phone green energy
