Aquaduct Bike Purifies Water As You Pedal 60
Mike writes "Winner of the '08 Innovate or Die competition sponsored by Google and Specialized, the Aquaduct is a pedal-powered concept vehicle that transports, filters, and stores water. The design has massive implications for communities where safe and secure sources of drinking water are not readily accessible."

Have they come up with something that will take my beer pee and filter it into water?
I live in Arizona and that would be a great thing to have in the desert.

Actually, if you forgo the filter and just bottle the pee, the result is virtually indistinguishable from American lager...

You shouldn't really be losing sweat on your bike, except to evaporation. The "wind in your face" greatly increases the efficiency of sweating on a bike. Well, unless you're on very rugged terrain where you don't often get up to speed. As for pee, well, if you have to pee when riding a bike, you are clearly not pushing yourself hard enough.

Some of the areas of the world with the worst water quality are very high-humidity, where you may sweat even if you're riding at 20 mph.
And as far as "not pushing yourself hard enough," in most of the world, a bicycle is primarily transportation, not exercise.

FYI, 20 MPH on a bike is a fairly fast speed. Your average transportation type bike rider (and indeed, some of the recreational bike riders) don't/can't ride that fast.

The amount of additional cooling provided by the effective wind over the body is linear with speed
No, it's linear with drag, which according to what you say, goes up by the power of your speed.

There are places in the world where people walk for miles so they can carry back heavy vessels of water, which may or may not be contaminated. The roads aren't likely to be much more than cart paths in many places. This aims at looking at that problem from end to end -- it carries the water, filters it for you, and is your round-trip conveyance.
This sounds like, while it's not a finished product, it's a hell of a good idea and a good start.
When you have a better solution that doesn't have as many limitations, get back to us.
I say kudos to the company developing this, and good on 'em for trying to work on this problem.

I do applaud the effort. However, I know our church funded a mission to take water from a river, pipe it to the village and filter it. Not only did it do what this bike does, it saves about a half dozen villagers from being eaten by alligators. The villagers are happy about this. The alligators less so. The locals did the manual work so that they could handle basic repairs if needed.

Here's my idea: bike + gravity-fed-through-filter tank. I still don't get why they need pedal power to push the water through the filter. I mean, they already need to lift the water to pour into the tank in the first place.

Yeah, because you can't ride a bicycle off-road. Oh, wait...
While I think this bike is a clear example of form following function, it looks like it has a lot of potential. If they designed it a little differently, it could also be able to carry supplies. Mind you, I'm not factoring in the amount of work required to pedal all that water around.

This could be useful for flooded areas, too. Along the Mississippi, Ohio, Illinois, and Missouri rivers, high flooding often means the rivers cover the water treatment and maybe the sewage treatment plants. So some cities go days or weeks without clean tap water during floods like 1993, 1997, and 2008. A few of these things per neighborhood would be a good emergency management step.

Which problem are you referring to? The problem of needing a drink from polluted water, or the problem of getting water to the residence? From what I read, the aquaduct bike handles not only filtration but transportation of a large amount of water (the water said a family of four needed 20 gallons a day, but they did not specify if that was the capacity of the bike's tank).On the other hand, we have a direct quote from the page you linked:

Does the filter remove bacteria from the water? I would think that the filter would become a haven for bacteria to breed propagate, especially when not in use. The main concern in countries where this would be useful are contaminants in the water and bacteria and I don't know of any filter that would effectively eliminate both without costing a fortune to replace every week.
This is more of a question than a criticism, seeing that I don't know if the filter technology exists or not...but a Brita filter isn

A boil and condense system might be another solution given that it could get away without he need to replace filters. And could also double as a stove.
Permanent magnets and metal coils are all that is needed to generate the heat. It could also have a stationary mode where the back wheels are off the ground so it could serve as a stove and avoid the need to collect/burn wood as well.
I grant that a boil and condense system would be a lot slower and require a heat sink. But then the entire water path could be

It will have "massive implications"? Yeah right. This is likely to cost quite a bit, and it is going to be far cheaper to have other systems, from boiling the water, to stationary filters, to sterilizing and sealing a well. From what I have seen in Laos (a developing country), the urban population buys bottled water, and the rural population either does nothing, boils water, or the village pitches in to install a sealed well with a hand pump. The later costs on the order of $100-$150 start to finish. Or I suppose you could buy a bicycle to filter water.
However, I must note that the people developing this did not claim "massive implications". Here is a quote from the article:
In its present configuration it is not a feasible solution for most developing communities due to production costs and durability. But in fairness to the IDEO team, they have stated that, "In its current state, the Aquaduct is a prototype aimed squarely at demonstrating a concept and raising awareness around the issues of clean water in developing countries. The Aquaduct team plans to continue the concept's development into an economically and technologically viable solution that addresses challenges such as cost, suitable purification technologies, and the logistics of addressing an issue that [affects] billions."

This vehicle looks cute, but is completely useless.
The thing works by spending some of the energy of your pedaling for a pump which then pumps the water trough a filter and into the "clean" tank in front.
Here's the thing, if you've got that filter, and can maintain it, you can achieve precisely the same thing by lifting the water you've fetched a single meter off the ground, and letting this fancy thing called *gravity* push it trough the filter.
