Instead of carrying water on your head you could roll it in front of you. You would probably have to fight your kids and your husband to do it. New technology for those who find water miles away. I suppose you could power a battery while walking home, too. ... and what else? Carry your dirty clothes to the well in the Hippo-Roller, fill it with water, add some biodegradable soap, walk home, hang the clothes out to dry and plug the Hippo-Roller into your irrigation system.

There is a version of this device which comes stuffed with the piping and valves necessary to set up a simple drip irrigation system. When you run out of water you roll the reservoir (Hippo-Roller) to the well and back and plug it back in.

I want to buy one of these things and give it to another human being who is straining under the burden of regular water collection. (Probably a woman with a bunch of kids trailing behind her). The micro-charity idea of Aura's house should work here. For 100,000 you can fund the creation of a manufacturing plant. Macro-Micro Charity.
