Could This Self-Filling Water Bottle Ease Global Water Shortages?

It all comes down to condensation – here is the science bit.

For condensation to happen, hot humid air needs to be cooled down. The Fontus has a small cooler which is installed in the centre and is called the Peltier Element. The cooler is divided into two: 

When powered by electricity, the upper side cools down and the bottom side gets hot. The more you cool the hot side down, the colder the upper side will get. Consequently, these two sides are separated and isolated from each other.

The air enters the bottom chamber at a high speed when moving forward with the bike and cools the hot side down. Moreover, when the air enters the upper chamber it is stopped by little walls perforated non-linearly, reducing its speed in order to give the air the needed time to lose its water molecules.

The condensing structure represents the largest surface in the smallest space possible. This provides a large surface for condensation to happen. Droplets then flow through a pipe into a bottle. The bottle can then be turned to a vertical position and loosened. Every kind of PET 0,5l bottle fits.

Experiments have established that it can harvest around 0,5 liters of water in just one hour, depending on levels of humidity. Now that is impressive.

  1. Absolutely brilliant. And the cost does seem reasonable.
    Can we purchase one as a “sponsorship” to be given to someone that doesn’t have access to fresh, clean water?

  2. I have to stop in for a minute in the middle of my schedule to give a shout out to “The Good Human” – you are such a contribution to a better way of life that I tip my hat off to you and support you and ask that you keep rolling on. You’re not alone and you’re a beacon of light. I share your site with all my friends. As like minded folks, we all have, hold and work towards a better world manifestation. We KNOW we can do better. I just started researching “Ubuntu” – (Ubuntu Planet) Do you think you can look into it and perhaps share your findings? Thanks.
