Smart Street-lights can be activated by mobile phone | livegreen by active

The Germans’ latest discovery is a system for sparsely populated urban areas which makes it possible to activate public lighting systems from a mobile phone.

The system, known as Dial4light, was tested for nearly a year in Dörentrup, a small German town of roughly 9,000 inhabitants, where public lighting, at least in certain areas, remains off all night. If truly necessary, it can be activated by calling the six-digit number which identifies that particular lighting system. This way, if you are walking home at night, all you need to do is dial a number, and the light comes on for about fifteen minutes or so.
