RSSThis winner of the Innovate or Die competition filters water through pedal power:
A peristaltic pump attached to the pedal crank draws water from a large tank, through a carbon filter, to a smaller clean tank. The clean tank is removable and closed for contamination-free home storage and use. A clutch engages and disengages the drive belt from the pedal crank, enabling the rider to filter the water while traveling or while stationary.
Aquaduct pedal-powered water transport and filtration - [via] Link.
A carbon filter is insufficient against pathogens, in fact it can act as a breeding ground for coliform bacteria (E.Coli), which are prevailent in surface water.
Some sort of disinfection (UV, oxidation like chlorine, RO/nano/ultra filtration) is needed for the clean tank for the water to be potable.

It's a lot like this:

I like the UV filter method, but I also like the trike transport method. But I think that the clean water tank need to be larger and closer to the ground, there's no reason for it to be in the front. Overall it's pretty cool, but I think too much was done to make it look good.
On another note, why do they have the website so resource intensive?

Why? Gravity works great.
