Barcelona is ready for innovation, and wants to become a smart city.

This video is a few weeks old now, but it’s a really great idea that’s worth sharing again. Instead of street lights that are always on, Barcelona has installed these motion sensitive lights on one of their streets – providing lighting only when someone is nearby.

Initially, I was a little concerned by this idea. A well-lit street is a safer street, but these lights have a broad enough range to provide lighting in advance of someone walking under them so my concerns were short-lived.

This video is part of GOOD’s series ‘Cities Rethought’, and as shown by comments in the original article, the idea has been met with some pretty rapturous feedback.
