Scientist Builds Self-Filling Water Bottle

Sorensen was reportedly intrigued by a very specific capability of the Namib Desert beetle that can extract water from air. The beetle's problem is that his living environment gets only half an inch of rainfall per year, but solved this challenge by using a hydrophilic coating, a surface with strong affinity to water, on his back to attract water, and a hydrophobic surface, a material that repels water, to store water. The mechanism is effective enough to provide the beetle with 12 percent of his water supply from air.

Sorensen apparently rebuilt this idea with a hydrophilic and hydrophobic surface to create a self-filling water bottle. The water source was create with a fan that was powered by a solar-charged battery. There was no information how long it takes to fill the entire bottle with water, but Sorensen told PRI that there are "more than three quadrillion gallons of water in the air." The entrepreneur considers any environment with moving air as a potential business opportunity.

"We actually see the maritime environment as really a very large market for us because humidity is actually constantly regenerated over a large body of water," Sorenson said. "Then we can pull that humidity from the air to support people who possibly take long trips on yachts, or provide a sort of potable water source that can be run off a solar panel while at sea."

    jupiter optimus maximusSounds better than re-drinking urine.You actually might be drinking the result of evaporated urine. Water has to come from somewhere

    Was it the urine you had been drinking while reading this comment?

    we can learn a lot of bugs and animals.

    Great idea. Pull all of the water from the air so that it won't rain anymore.

    Getting lazier and lazier all the time.

    Not enough energy to get up and grab a water bottle, or fill one up?

    I think Sharp or some other company was using moths' eyes in their research on developing a display that combined both the matte's anti-glare and the glossy's high contrast/quality characteristics.

    The moths eyes' had nanocoating that allowed them to see well in the dark, without alerting every predator in a 1 mile radius.
