Dew Bank Water Bottle Harvests Water From Air
What do a fog beetle and a water bottle have in common? Apparently, quite a bit. The fog beetle has ridges on its back that allow it to collect dew from the moisture-laden morning air, which the beetle then uses for drinking water. Seeing this naturally efficient process inspired Pak Kitae to design a truly innovative new water collection device - the Dew Bank.
The Dew Bank is a round stainless-steel ridged dome attached to an enclosed channel. Evening temperatures are cooler than during the day. A Dew Bank set out in cool night air will become cool as well. In the morning, the stainless-steel is cooler than the air. Moisture in the air then condenses on the Dew Bank dome ridges and slides into the channel along the Dew Bank base. Check out the video below.
Kitae believes his Dew Bank could collect enough moisture from the air for one glass of water. A bigger Dew Bank might be able to collect even more water. For the millions of people who lack access to drinking water, the 2010 IDEA Design Award-winning Dew Bank could be a literal life-saver.
