Solar street lights and other street light solutions using advanced solar technology

Troubled by choosing decorative lights? ---- what about a light tree

To design best solar street lights, several problem need to be solved: firstly, lower cost, both for installation and maintenance; long life, because solar street lights will play an important role in our daily life, reinstallation will bring inconvenience to us; beautiful, solar street light are very important decorative element of city. The first two points could be solved with the development of technology. But the last need the help of artists.
Recently A brilliant solution that combines public art, pedestrian scale lighting, and greenery is easy to imagine beautifying parks, paths and public venues. The Light Tree, designed by Omar Ivan Huerta Cardoso uses hydroponic techniques with LED and solar cell technology.
The Light Tree is constructed of plastic and is filled with water. The street light is generated by several ultra-bright LEDs located at the base of the fixture. The light is conducted through water that fills the interior of the structure. The water also feeds the seeds or saplings planted at the top of each of the branches. These saplings can either be allowed to grow to a specific size, or they can be removed, transplanted and replaced with new plants.
The Light Tree “uses a Highly-Efficient 3-Dimensional Nanotube Solar Cell for Visible and UV Light,” which enables light absorption from visible and ultraviolet light and double the efficiency of light to energy conversion. This solar panel is located at the base of the Light Tree but is designed to work in shady or cloudy conditions. With the development solar technology, I believe that we could design a better street lights that will collect solar energy effectively.
