Dr. Fazale Rana of Reasons to Believe tweeted this cool example of biomimetics from Science Daily.
A UT Arlington engineering professor and his doctoral student have designed a device based on a shorebird’s beak that can accumulate water collected from fog and dew.
The device could provide water in drought-stricken areas of the world or deserts around the globe.
Xin Heng… a doctoral student in Mechanical and Aerospace Engineering, and Cheng Luo, MAE professor, have made a device that can use fog and dew to collect water.
Cheng Luo, professor in the Mechanical & Aerospace Engineering Department, and Xin Heng, PhD candidate in the same College of Engineering department, published “Bioinspired Plate-Based Fog Collectors” in the Aug. 25 edition of ACS’ (American Chemical Society) Applied Materials & Interfaces journal.
The idea began when Heng saw an article that explained the physical mechanism shorebirds use to collect their food — driving food sources into their throats by opening and closing their beaks. Luo said that inspired the team to try to replicate the natural beak in the lab.
“We wanted to see if we could do that first,” Luo said. “When we made the artificial beaks, we saw that multiple water drops were transported by narrow, beak-like glass plates. That made us think of whether we could harvest the water from fog and dew.”
Their experiments were successful. They found out they could harvest about four tablespoons of water in a couple of hours from glass plates that were about 26 centimeters long by 10 centimeters wide.
Now, if we are lifting designs out of nature, then shouldn’t we give honor to God for putting the designs in there in the first place? I really think it’s important to give God credit where due for his clever designs, even if you’re not a big fan of the shorebird. I also think it’s interesting that it’s engineers who made this application of something in nature, not biologists. Also, I feel I have to mention that the birdy is also cute, which is not insignificant, if you like birds as much as I do.
