Dial4Light with your phone to turn on the street lights

Juniper Foo | Feb 24, 2009

Imagine being able to control the street lights with your mobile phone. This isn't a prank, but an eco-friendly solution that's now in place in parts of Germany. We won't suggest this for streets like Harlem or the dodgier parts of Asia since it's so easily subject to abuse. The (I must add) responsible denizens have put in place a system called Dial4Light which lets cell phone users turn on the street lamps only when someone actually needs illumination.

Much like your very own On/Off switch at home, this one requires you to dial up the lights, with a 15-minute grace period before it gets pitch black again. And the best bit, a reported cost savings of 25 percent in power bills for the the towns, not to mention everyone doing their bit in reducing their carbon footprint. Just don't leave home without your phone.
