Generate shadows without trees: vegetable awnings, a new way to generate shadows in the city.

I found these kind of cool as an idea, as they can be added rather easily to existing cities and provide some greenery without taking up space, while providing shade:
There is no flex in the cables, they are under tension. The material inbetween holding the plants? I'd make that rigid too, even if designed to look like fabric but I can't specifically see soil so these could be hydroponic rockwool (much lighter) watered by an autosystem or a chap with a portable water bowser. Could use fabric then and let excess water drip through for ten mins once a day.
