The Aquaduct

Not sure how easy this device would fair over tough terrain, also the water carrying tank seems pretty small on the front and theres lots of parts to go wrong overall. BUT that said I really love that the bike's clutch can allow the bike to be stood stationary and you can still peddle and filter water. The bike could be used by a community, children to also contribute to filter water. Another aspect of this is concept which I really like is that it combines recreation / fun with something which could save lives. Could an everyday item such as a playground roundabout be used to filter water or generate power but still allow children to use it for fun.
