Have you ever heard of an Elephant Pump? Today, I found out that an Elephant Pump is a low-cost well pump based on a type used in China over 2,000 years ago. It can be made with local materials and is powered through a contraption that looks much like a bicycle.
How did I figure this out? A friend sent me a link to the awesome website AfriGadget. This site is dedicated to showcasing the ingenuity of Africans. Reusing products like old keyboards, plastic bottles, and other assorted items to devise bottle openers, shoe-shine stands, bamboo bikes, and even a biodiesel conversion kit. They bring the word sustainability to a whole new level.
Also, they have a whole section on sanitation and water – how to build “keyhole” gardens, directions for a VIP (Ventilated Pit Latrine), Homemade Water Filters, Kick Start Pumps, and more. AfriGadget really should team up with Akvopedia, another open-source water and sanitation destination.
