Natural inspiration for collecting water in the desert



Men need a lot of time to get a poor diet, but they can not survive if they do not clean water. In some parts of the Earth it is impossible to live, there is no nearby water source available, but paradoxically, to survive animals and plants. How do they do it? Where do they manage to survive the water?

The three scientists at Ohio State University closely monitored Cactus, beetle and small herbs that grow in the deserto. They've watched They survive water collection from a damp atmosphere overnight.



We think: How can we make water to collect nearby air? "And so, we see things we already have in nature: cactus, beetle, deserts grasses.








"We thought:" How does the surrounding air collect water? ", Explained Bharat Bhushan, Eminent Scholar and Howard D. Winbigler." Thus, we already see things in nature: cactus, beetle, desert grasses. "

His findings, published by the Royal Philosophy of the Royal Society. There are cactus, beetle and desert grasses to collect condensed water from the foggy night, to collect airborne droplets and filter them to roots or reservoirs, providing enough hydration for extreme weather survival.

Water droplets accumulate beetle It has a back side, and then slipped between the protrusions at the beak of the beetle.

du deserts grasses They collect water on leaf tips and channel water through their systems.

du cactus They collect fresh water on the ends, and then drips from the conical spines to the base of the plant.

Bhushan group studied and realized the method used by these three living creatures Although they were similar to the system, they were able to build larger systems for the extraction of mist or night condensing water.

Conical, most effective forms





The different surfaces were able to accumulate with water and began to investigate which surfaces were most effective. Using 3D printers, they were built with blades and nails on the surfaces, and then created closed and fuzzy environments to see the system that has the most water.



Conical shapes are better

That's why it happens why the physical phenomenon is due to the pressure of Laplace's gradient. The water tip of the cone is piled up and then poured into the bottom of the cone, because the deposit is waiting



With different experiments, the conical forms saw more water than cylindrical forms, "what was sensible, what we know about cactus," said Bhushan. That's why it happens why the physical phenomenon is due to the pressure of Laplace's gradient. The water cone tip is piled up and then poured into the bottom of the cone because it is waiting for a reservoir.

Surface surfaces moved faster than smooth surfaces, over-surfaces ungrooved surfaces accumulated less water.







The beetle's surface material is heterogeneous, with hydrophobic locations surrounded by hydrophobic regions, which makes it easier for beetles in the mouth



Cone materials were made from hydrophobic materials, because they consisted of water droplets. "The surface of the beetle material is heterogeneous, with hydrophobic hydrophobic regions with hydrophilic sites, which is easier to cross in the mouth of the beetle," explained Bhushan.

The researchers also experimented with a multi-cone structure and found more water accumulated in water between one or two millimeters of water between the spots.

Labor is currently in the laboratory, but the goal of science is to create large structures in the forests to accumulate large amounts of water.



Water supply is a very important problem, especially for people living in dry areas worldwide. Using biologically-inspired technologies, we can bring clean water to the most efficient way possible for people across the globe.








"Water supply is a very important issue, especially for people living in the most dry places in the world," said Bhushan. "Using biologically inspired technologies, we are able to respond to the possible challenges of clean water to the most efficient way for people all over the world."
