Solar trees

Here comes a great innovation! Thus, the 3D streets of Europe could soon be lit by 3D "solar trees". These 3D Solar trees are self-contained streetlights that could save 3D cities energy and money too. Unlike regular 3D streetlights, the 3D Solar trees do not require costly underground wiring to install, and they are immune to blackouts. Compared to conventional 3D streetlights, the 3D Solar trees emit much less light pollution, because 3D LEDs generate a very directed light. The 3D Solar trees also incorporate light detectors! So the lights automatically turn on sunset and off at 3D sunrise.
