The Aquaduct is a bike that purifies water! Pour water into one tank at the back, and start on your way home. The pedal power activates the filtration system and when you arrive, the clean tank at the front is filled with filtered water.
This is a product designed for the developing world, where women typically transport contaminated water and must boil it at home, wasting wood and energy all along the way.
A family of 4 needs a minimum of 20 gallons per day.
The Aquaduct can also be used to filter water while stationary.
