The Aquaduct is pedal powered vehicle that transports, filters, and stores water for the developing world. A peristaltic pump attached to the pedal crank draws water from a large tank, through a filter, to a smaller clean tank. The clean tank is removable and closed for contamination-free home storage and use. A clutch engages and disengages the drive belt from the pedal crank, enabling the rider to filter the water while traveling or while stationary.
In 2008, the Aquaduct won the Innovate or Die contest put on by Google and Specialized. The contest challenge was to build a pedal powered machine that has environmental impact. For more information see: The Aquaduct Blog.
