Cooped Up? Get Uncooped.

This concept tricycle purifies water as the rider pedals it. Why would you need a bike that purifies your drinking water while you peddle it? You wouldn't, unless you lived in a developing country where you have to make long daily trips to your nearest water source, that, by the way, is very likely undrinkable. Amazing.
