In contrast to purely superhydrophobic surfaces, small water droplets adhere to the patterned material and do not easily roll off, similar to the Stenocara beetle's surface. Stenocara gracilipes has bumps that attract water and troughs that repel it; this way, drops collects on the bumps, then run off through the troughs without being absorbed, so that the water reaches the beetle’s mouth. Some of the world’s smallest creatures are also be some of the toughest. Their self-filling water bottle is said to be capable of storing up to three liters every hour. This giving the earth a bit of an advantage when it comes to technology and evolution. To build fog-harvesting devices that work on a human scale, Chhatre says, “The Water scarcity is one of the bigger problems plaguing the world today. Tiny bumps cover the surface of the beetle’s shell. The shells of the beetle are covered with small bumps which serve as collection points. • The polymer layer avoided the extraction of pristine CNTs from substrate. But the Stenocara beetle’s back surface is ideally suited to capture this moisture. Like Water Off a Beetle's Back. The shell is covered in the slick which allows the morning fog to directly enter the beetle's … They created water-grabbing bumps with … Stenocara gracilipes. With Patrick Aryee. Water Harvesting. The natural ingenuity of the Namib Desert beetle has inspired many researchers to search for fog harvesting … This is one of the most arid areas of the world, receiving only 1.4 centimetres (0.55 in) of rain per year. The bumps are unique in nature in that they have water attracting tips and water repellent sides. Chp9-10-11 Water Supply Systems, Waste and Reuse Systems, and Fixtures and Appliance. In 2001, they read in the journal Nature that the dime-size Stenocara beetle in the Namib … Stenocara Solution. That the idea behind this concept by IDEO which is directly inspired by nature’s best fog catcher—the one found in the back of the Stenocara beetle of the Namib Desert. The resultant samples with patterned wettability demonstrate water‐harvesting efficiency in comparison with the silica PDMS‐coated superhydrophobic surface and the Pt nanoparticles‐coated superhydrophilic surface. Advertisement “Under a electron microscope it looks like a … The researchers used a humidifier to test the material's properties for water harvesting from humid air. The maximum water‐harvesting efficiency can reach about 5.3 g cm −2 h −1. The peak of each bump is hydrophilic, meaning that it attracts water. The blueberry-size, long-legged insect leans its bumpy body into the wind, letting droplets of fog accumulate and […] 27, 2019 , 9:55 AM To survive in the arid wilderness of southwestern Africa, the Namib Desert beetle harvests water from thin air. The new patterned structure based in CNTs has been designed to biomimic the Stenocara beetle one. Being actually an inexpensive way to provide clean drinking water, this fog harvesting device could be perfect for poorer countries, where water scarcity is still an unsolved problem. Beetles that harvest water from desert air have inspired the creation of printable surfaces that improve on nature with the aid of glass nanoparticles. When the morning fog rolls in, the Stenocara gracilipes species, also known as the Namib Beetle, collects water droplets on its bumpy back, then lets the moisture roll down into its mouth, allowing it to drink in an area devoid of flowing water. That the idea behind this concept by IDEO which is inspired directly from nature’s best fog catcher — the one found in the back of the Stenocara beetle of the Namib Desert. The waxy regions then help direct the droplets into the beetle’s mouthparts. The Stenocara beetle is a creature collecting water. The stenocara is equipped with an armor like shell covered with bumps. One basic principle of a good fog-harvesting device is that it must have a combination of surfaces that attract and repel water. One group of researchers looked to the Stenocara, or Namib desert beetle, for a solution. It is found in the harsh desert environment but can survive in those conditions as well. These results are compared to the hydrophilic−hydrophobic pattern present on the Stenocara beetle's back, which is used by the insect to collect water in the desert. Developing nations, in particular, are the victims of poor water management leading to fewer sources of potable water. Countries like Qatar are even using these on a wide scale. Keeping this in mind, designers are coming up with solutions that claim to be able to harness water from air. 67 terms. In this sense, the beetle’s physiology is an inspiration for human fog harvesting, not a template. Stenocara gracilipes is a species of beetle that is native to the Namib Desert in southern Africa. To address the worldwide issue of water scarcity, which is threatening our sustainable economic development and ecological security, an efficient water-collecting surface with fast-capturing capability and easy drainage is essential. In the arid Namib Desert on the west coast of Africa, one type of beetle has found a distinctive way of surviving. ... YOU MIGHT ALSO LIKE... 123 terms. One basic principle of a good fog-harvesting device is that it must have a combination of surfaces that attract and repel water. Many species of beetles, according to … Inspired by Stenocara gracilipes, a beetle found in the Namib Desert, MIT engineer Shreerang Chhatre developed a simple and efficient device that can harvest fog. They say that, like this beetle, their bottle can pull water from the air. In the arid Namib Desert on the west coast of Africa, one type of beetle has found a distinctive way of surviving. The slopes and valleys in between bumps are hydrophobic, meaning they repel water. Scientists have been studying its wings and back. National Geographic describes the Namib Desert Beetle, also known as the stenocara, as a desert MacGyver. Solvin Zanko/Minden Pictures By Eva FrederickNov. Rainwater harvesting is a technique of collection and storage of rainwater into natural reservoirs or tanks, or the infiltration of surface water into subsurface aquifers. Potential applications include fog harvesting, microfluidics, and biomolecule immobilization. Its morning routine includes standing atop a sand ridge and facing the wind at an angle, head down and bottom up. The beetle’s built-in water collection system allows it to survive in one of the driest climates on Earth. To build larger fog harvesters, researchers generally use mesh, rather than a solid surface like a beetle’s shell, because a completely impermeable object creates wind currents that will drag water droplets away from it. • PE layer improved the composite long-time performance for water collection. When the morning fog rolls in, the Stenocara gracilipes species, also known as the Namib Beetle, collects water droplets on its bumpy back, then lets the moisture roll down into its mouth, allowing it to drink in an area devoid of flowing water. • The best result reached show that this material has high potential to dew harvesting. Air Date: Week of November 16, 2012 stream/download this segment as an MP3 file. While the earth has been around for approximately 4.54 billion years. Though southern Africa's Namib Desert is lucky to get a half inch of rain a year, STENOCARA, THE NAMIB BEETLE, finds more than enough to drink.When fog rolls in off the Atlantic, it raises its rear to the breeze and waits for water to condense on its hydrophilic (water-attracting) shell. Inspired by the fog-harvesting capability of Stenocara beetles in the Namib Nanoscale Advances HOT Article Collection Picture Credit: Moongateclimber/Wikipedia Commons. Harvesting water like the Stenocara beetle. The Namib Desert beetle (stenocara gracilipes) (Photo: Moongateclimber/Wikipedia Commons) A small start up company, inspired by a desert beetle, is using nano technology to develop a self-filling water bottle. It’s really no secret at this juncture: access to water is pivotal to any sustainable civilization and life on this planet in general. The Stenocara beetle survives in one of the most arid places in the world – the Namib Desert in southern Africa. An engineer and aspiring entrepreneur works on fog harvesting, the deployment of devices that, like the beetle, attract water droplets and corral the … Similar surfaces inspired by the Stenocara have collected up to 10 liters of water per square meter every hour. The Namib Desert beetle gets its water from fog. Like, for instance, beetles. Exposed to ocean fogs, tiny water droplets cling to the top of the hydrophilic bumps and accumulate there. Namib desert beetles (Stenocara gracilipes) survive in one of the most arid regions on Earth by turning their backs to the breeze and using their wings to collect water droplets from fog.
