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 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.
