Making my requisite rounds of the substainability and green technology news sites this evening and just came across this story from EarthTechling about concept lighting technology being tested in Europe called the Sustainable City Light. The idea is that by day, these light poles would be (in effect) sort of urban art objects. By night, they would “bloom” into LED street lights — triggered by motion detectors that sense when someone is walking by. The concept, by Philips (there’s a concept animation at this link), is that this approach is less wasteful than leaving the lights on all the time.
I dunno, though. As a female who peers around every corner when it’s dark, I would want to make sure that motion detector could respond instantaneously.
