City lights have to be one of the biggest energy suckers around, and making them more efficient should lead to massive energy savings. The sustainable city lights concept from Philips Design delves into the same idea, making the lights smarter and better looking. The most interesting part, however, has to be the way these lights bloom like flowers, to gather the sun’s energy.
Opening up like flowers lets the lights harvest solar energy during the day, while the petals close during the night to give a more conventional street-lamp type look. It isn’t just solar power these lamps harvest, they also make use of the wind’s energy. Energy efficient LEDs automatically come up to provide lights when needed.
Basically, these city lights generate enough energy to keep them going and to do their job well. If they generate a surplus of electricity, the same is sent to the grid, or fed to other nearby lights in need of juice.
