    Harvesting water from the air

    http://www.smithsonianmag.com/ist/?n...air-180957986/

    A company called Fontus is currently crowdsourcing to develop water bottle works that moisture from the air, using the Peltier effect, which creates a heating/ cooling differential that results in condensation by way of a solar-powered small condenser. Similar to bringing an iced drink outside on very hot day - droplets form.

    One version that attaches to bicycles (The Ryde) can yield a half-liter of water in one hour, in very good conditions - 80%-90% humidity, it can yield a half-liter of water in one hour.

    Future builds will include a carbon filter to trap airborne particulates.

    Using existing humidity for water supply is not a new idea.

    Ancient Byzantine ruins revealed dew collectors. They were named Ziebold Collectors, after the person who discovered them in the 1900's....




    Which inspired the Knappen collection system, or air wells.. Mason stones collect heat during the day, then cool at night.





    A newer approach is using nets to catch airborne condensation ....

    And a more portable, viable collection system made of lightweight materials, which yields up to 1.5 liters overnight.







    Good article on dew collection systems

      I just walk into my kitchen and turn the faucet on. It yields a liter of water in about 6 seconds.

        Good thing you don't live in Flint, Michigan or many Indian reservations. They either have none, or it's contaminated.

          Great post!

          i will definitely buy a couple of the bottle ones.
          A day may come when the courage of men fails, when we forsake our friends and break all bonds of fellowship, but it is not this day. An hour of wolves and shattered shields, when the age of men comes crashing down! But it is not this day! This day we fight! By all that you hold dear on this good Earth, I bid you stand, Men of the West!

            Predicted price will be in the $40 range once they're available. Not bad.

                    I saw this somewhere else. They have product already. Sits on your bike and,fills up on its own. Solar powered, so continuous.

                        You're welcome, bowclan

                        gamgee, that would be good. They've got the solar piece and heat element in there already. Just heat up the water and have the coffee layer under the particulate filter.

                          I'll probably buy a whole case of them to get enough to put in each of my spare load out for dependents.

                            Why is it a bike? Couldn't it just be anywhere? I haven't read the article or description completely.

                              They had one that was pretty much sit anywhere. They also had one that mounted to a bike and filled the bottle with water as you went down the road. I think it is appealing to mountain bike riders.......
