Verstecktes Licht

"Invisible Streetlight emits light at nighttime by saving energy from sunlight during the day. ... It does not require a support because the flexible body in the shape of tree branch is directly installed to the trees lining a street. Installation is simple in parks and outskirts of urban centers, and the Invisible Streetlight does not spoil scenic beauty of the surrounding areas." und ist von Jongoh Lee. meint auch PWFontes
