I've always been fascinated by objects with multiple functions: Swiss Army knives, chairs that fold into step ladders. And I've always wondered why there is not more thought given to what is sometimes called 'Appropriate Technology' - modest designs that fit the environment, do the job and fill a need- or even multiple needs- at a modest cost.
Both of these characteristics are met in spades by the Aquaduct - a bicycle with a water tank and a filtration system operated by pedal. For the vast number of people-- especially women and girls-- who must walk long distances at great cost in terms of both physical wear and tear and time in order to collect water the genius of this invention can hardly be overstated. The Aquaduct cuts time to the water source by allowing the water collector to ride instead of walk. Then, having filled the tank, she rides back home, forcing the water through the filtration system and sending the clean water to the container in front.
This wonderful machine was the winning entry in the 'Innovate or Die' competition held by Google and Goodby Silverstein & Partners to encourage the development of pedal-powered solutions to environmental problems.
