Project41's director, Andy Pierce, came up with Project Rainmaker. According to their website, "Project41 develops tools that empower the poor to lift themselves out of poverty." While volunteering in Haiti, Pierce saw a small hand pump drawing about 5 gallons a minute from a rain-capture system. Brainstorming and researching, he saw people utilizing a bike to power a centrifugal pump. Eventually, he rigged a pedal-powered pool pump that delivered about 50 gallons a minute to the health center in Uganda where it was installed. That's when it was decided Project Rainmaker could also be used for agricultural purposes. Project Rainmaker is a human-powered irrigation that draws water from a nearby source via a pool pump powered by someone pedaling a free-standing bicycle.As arduous as it sounds, it's better than transporting water by the bucketful from a river to the crops.
