Aquaduct by IDEO: the bike that purifies water as you pedal

The Aquaduct by IDEO is a cycle like no other, and that is because the bike purifies water as you pedal. This concept tricycle was being shown off at the Design Indaba conference which was held in Cape Town, South Africa.

The bike was designed so that is can help people who live in the developing world, who have to make long journeys when going for water. This water is often unsafe to drink as it has not been purified. The Aquaduct tricycle has a large water tank on board, when you cycle it will draw the water through a filter and is then stored in a second tank which is placed on the handle bars.
