Designed by Ideo, based in Paolo Alto, the Aquaduct has a water tank that uses the energy of cycling to filter the water into a smaller container – providing 8 litre of safe drinking water.
The idea is still very much a work in progress; it was created for the Innovate or Die competition whose sponsors include the search engine Google. The Ideo team won but as Paul Silberschatz, one of the team, said, there is still a lot of work to be done to make it commercially viable.
