Hi BEST members, The city of Eindhoven is introducing a sustainable city-lighting system. Dutch startup, Tvilight, offers this LED lighting system which is controlled by computers and the street lantern can turn on or off depending on how active the street is. The street lantern is dim if nobody is there and turns on when a car, bike, or pedestrian is passing by the street. LED streetlights reduce energy costs and is more energy efficient compared to regular streetlights. Usually city streets are empty after 10pm but having the dim streetlight provides security to the residents. All the lights contain colors with a bit of blue and green which will enhance the pedestrian's feeling of comfort. The street lantern can adapt to different types of weather and even flash red if a storm is approaching. Dutch artist, Daan Roosegaarde, has a highway illumination project called Smart Highway which he designs interactive roads. Giant snowflakes and flowers are painted in illuminating paint that appear when a car approaches it and it lets the driver know the temperature. The initial cost is expensive but is worth it in the long run as the system reduces carbon dioxide emissions and lower energy costs. This lighting system is providing an energy efficient and enjoyable environment. http://www.theguardian.com/sustainable-business/sustainable-smart-lighting-systems-cities "Illuminating Cities with Sustainable Smart Lighting Systems."
