Have you ever left the lights on in your house for days at a time and then gotten a ridiculously crazy electric bill the next month? Can you imagine how much cities have to pay to keep all the street lights on and maintained every day? The cost is astronomical, but it could be diminished quite a bit due to Dutch designer Christian Shuh's new streetlight design called Tvilight.
Christian Shuh's new streetlights are designed to light up only it senses people around through its wireless sensors. When people aren't around, the streetlight dims, using the least amount of power possible while still lighting the street enough for oncoming vehicles and pedestrians to see where they're going. The system is designed to recognize the difference between people and animals, so it won't cut on unnecessarily.
