Self-filling water bottle draws water from the air.
The water bottle draws inspiration from the Namib Desert beetle, which is able to draw in 12 percent of its weight in water from the air using hydrophilic areas on its back which cause water to condense.
“We use nanotechnology to mimic this beetle’s back so that we too can pull water from the air,” Sorenson told PRI. “We see this being applicable to anything from marathon runners to people in third-world countries, because we realize that water is such a large issue in the world today, and we want to try to alleviate those problems with a cost-efficient solution. We are looking to incorporate this in greenhouses or green roofs in the immediate future, and then later on, we’re looking to see how far we can really scale this up to supply maybe farms or larger agricultural goals.”
Arguably the most remarkable part might be that fact that Sorenson insists the technology does not require much energy; he said the company’s showed how solar cells and a rechargeable battery can be enough. This means the device could potentially be attached to vehicles, buildings, or even a running human, and still be able to grab all the power it needs supply to move the air over the specially-coated surface.
