Water from a bike on the side of a road - risk of the owner not taking
care of his equipment, not appetizing! If it were my own bike, sure.

That bicycle is going to need a bicyclist doing a Herculean effort to
pull 3 tons of clean water. OR one heck of a long hose!

5 gallons a minute
If I did my math right, 3 tons in 10 hours comes out to about 1.25 gal/min. That's not a lot, especially using since bicycles use leg power efficiently. Most of the effort would be pushing the water through the filters.

RE: A bicycle that produces drinking water may help thirsty villages
could this filter system be applied to stationary bikes in a gym? that
way, water lines can be permanently hooked up and maybe provide
pure drinking water for drinking fountains or sinks. if people are
paying to go to a gym and pedaling anyway for exercise or calorie-
burning, can this energy be harnassed for water purifying?
AND, can it be done for much less than 6,000$ that is very
expensive but i wonder if it was a more stationary system, could the
price be cheaper?

@rivardau
You're definitely on to something. There is a gym in Portland that is harnessing the energy from clients to power lights and the facilities' other electrical needs. It's mind-blowing when you think about how much energy we're regularly expending that can be used to power something.

RE: A bicycle that produces drinking water may help thirsty villages
The article says to put the bike on a stand once you have a water source. If it is only a stationery bike, it would have to be carried to the water source. Without it being stationery, it can be ridden to the water source. That would be more effective. While the idea of bikes in a gym pumping out water sounds good, the gym would need to have a source of ground water from which the bikes could extract and get to work.
I was thinking it would be nice for farmers in poor, arid countries. They could tap into the water table (if possible) with the bike and then pedal to irrigate their farmland. Imagine how much better their crops would grow if they just had some clean water every couple days. For them - this could be a game changer.

What I see in the picture and the description adds up to less that $600. I doubt that the people who have an actual use for one would even consider paying so much.I doubt more that they could pay it.
