Rainwater harvesting is a big deal, especially in Australia. Designer Chris Buerckner has developed this idea for a harvesting umbrella for urban sports grounds; it spreads out in the rain to gather water and channel it into an underground tank, and folds up to get out of the way at other times (unless it is being used to provide shade as well)
I do wonder how this is better than just letting the water soak into the ground and be stored naturally; I suppose the release of the water can be more accurately controlled.
And Chris does owe a debt to our Japanese practitioner of Chindogu, the inventor of the Personal Rain Saver. Chris Buerckner via Ecofriend
