Here is an interesting concept for rainwater catchment. Created by Mostafa Bonakdar, a design student from Tehran, Iran, the structure is both a shelter during rain as well as a drinking fountain. It features both solar power and rainwater collection, with the solar power running a purification system inside. The structure can act as a bus shelter, a cover for benches in the park, or a number of other locations where both an awning and a bit of fresh water are welcome.
Perhaps the shelters could be temporary, installed during springtime when the weather varies enough to offer rain one day, and a warm day the next. Or it could be set up to release extra water into the ground after a certain duration in the tank -- after all, it'd take quite a bit of energy to constantly filter and sterilize the water held in the tank, which means the solar panel would have to be incredibly efficient or quite a bit larger than pictured here.
Sure it's not exactly practical nor realistic, but it's an interesting concept nonetheless for providing several services at once with renewable energy and resources.
