The Grass by darja tokranova from estonia

"The Grass" street lights were designed in natural shape of the grass stems, imitating it's simple shapes and adding greenish touch in city landscape.
This is an eco-friendly concept which includes such green technologies as solar panels for collecting energy at daytime and recycled plastic for the whole stem part.
Collected energy can be used entirely or partly for shining at night, making the city illumination system almost self-sufficient. All the technologies are available nowadays.
