Greetings buddy TechWorld in this post I will discuss about Self-Filling Water Bottle Converts Humid Air into Drinking Water.
While you're pedaling furiously on the uphills, your water bottle could be hard at work, too.
Fontus, a water bottle that takes in moisture from surrounding air,
can produce clean, drinkable water in under an hour (assuming the air is
also relatively clean).Read more >>
Created by Austrian industrial designer Kristof Retezár, Fontus was designed to help people in water-scarce areas, including some 1.2 billion people around the world. Rather than relying on complex water purification systems, Retezár wanted to make something simple and portable.
"This is simply condensation of the humidity that is contained in the air," Retezár told Live Science.
When humid air flows into the device, it hits a series of hydrophobic "teeth," which look kind of like toothbrush bristles, that help turn the water vapor into actual droplets. A small solar panel on the top of Fontus keeps a battery charged.
Retezár says the bottle works best between 86 degrees and 104 degrees Fahrenheit and between 80 and 90% humidity. Over the course of an hour, Fontus can produce roughly 0.5 quarts of water.
The current prototype isn't perfect, the designer concedes.
Fontus can filter out some large contaminants, like bugs and dust, but the filter isn't designed to keep out small contaminants like sediment. In future models, Retezár hopes to install a carbon filter that will make it more useful in water-scarce regions where air quality is also an issue.
Retezár plans to launch a crowdfunding campaign soon to bring Fontus to the market by the fall. He hopes to get the price under $100.
"This is simply condensation of the humidity that is contained in the
air," Retezár told Live Science. "You always have a certain percentage
of humidity in the air, it doesn't matter where you are — even in the
desert. That means you would always potentially be able to extract that
humidity from the air."
"Because they're hydrophobic, they immediately repel the condensed water that they created, so you get a drop flow [into the bottle]," he explained. "Basically, you're taking air in a vapor state and converting it into a liquid state."
Fontus can produce 0.5 quarts (0.5 liters) of water in 1 hour in what is considered "really good" conditions, with temperatures between 86 degrees and 104 degrees Fahrenheit (30 to 40 degrees Celsius) and between 80 percent and 90 percent humidity, Retezár said.
The prototype includes a filter at the top to keep dust and bugs out of the water, but currently it does not include a way to filter out potentially harmful contaminants.
"The water you get is clean, unless the air is really contaminated," Retezár said. "We're thinking about making a bottle that also has a carbon filter, and this one would be for cities or areas where you might think the air is contaminated. But originally, this water bottle was thought to be used in nature, and places where you wouldn't have contaminated air."
Retezár is also working on a stand-alone version that uses an inverted ventilator to suck air into the system (rather than relying on the airstream created from a moving bike). This next-generation version could be used in regions of the world where humidity is high, but water is scarce.
"The idea was to solve a global problem: water issues in areas of the world where there is very little groundwater but very high humidity," Retezár said. "My intent was to invent a machine or device that would be able to filter the humidity in the air and turn it into drinkable water."
Final umpteen this post, may be useful and do not forget to always update in TechWorld.
Thank You..
