artifical shade

Designed for urban areas without a lot of trees these benches have a flower like structure coming from the tops of them to provide the sitter with shade from the sun on hot days. The center of the structure also has a device to catch wind and store its energy and turn that into a lighted are to sit at night. The idea of this is a good one yet for some reason I don't like the way they've designed these at all. Depending on the place where you put this, you may or may not want it to look like a flower. Also what if you don't live in a windy area, would the lights at night be useless? Instead they should make the shade "petals" with solar panels on top. I think that would be a more effective way of harnessing the energy. also I build in a tilt function because the sun doesn't always stay in one spot.
