The Army recently handed Case Western Reserve University and Waltham, MA’s Infoscitex Corp. a joint contract to start investigating a “Microfabricated Biomimetic Artificial Gill System… based on the subdividing regions of clef, filament, and lamellae found in natural fish gills.” In the first phase of the program, “gas exchange units will be designed and demonstrated for rapid, efficient extract of oxygen from surrounding water.”
“An advanced breathing apparatus that mimics the efficiency, simplicity, and durability of the gill-swim bladder found in fish could greatly improve human maneuverability and sustainability in both aquatic and high altitude settings,” the contract announcement reminds us. Sure could.
Maybe the army should search the net before spending our tax dollars inventing something that already exists. Apparently, it isn't even terribly complicated. "Alan Izhar-Bodner, an Israeli inventor, has developed a way for divers to breathe underwater without cumbersome oxygen tanks. His apparatus makes use of the air that is dissolved in water, just like fish do. The system uses the "Henry Law" which states that the amount of gas that can be dissolved in a liquid is proportional to the pressure on the liquid. Raise the pressure - more gas can be dissolved in the liquid. Decrease the pressure - gas dissolved in the liquid releases the gas. This is exactly what happens when you open a can of soda; carbon dioxide gas is dissolved in the liquid and is under pressure in the can. Open the can, releasing the pressure, and the gas fizzes out."
Alex Wood is an addict but won’t give up his smartphone. But he has five strategies for limiting its control over him: “I used to wake up tired. My body would ache and my head felt sore, like waking up with a hangover. Finally, I took control, like attending an AA class for addicts, I […]
Ok, it’s not just solar powered. It’s also an anti-theft, waterproof marvel that keeps my phone’s power bar from ever getting into the red.Sure the idea seems obvious now – tuck a gigantic solar powered battery pack into an exposed slot and turn the wearer into a walking energy harvester. Simple maybe, but I didn’t […]
Thread count isn’t like one of those deceiving metrics like camera megapixels or Facebook friends—more threads are always better if you can afford them. If price was no object, we would all be snoozing soundly bundled up in 1.8 kilo-thread sheets every single night. Guess what? Price doesn’t have to be an object with this […]
Maybe it’s entirely because of podcast ads, but drag-and-drop tools like Squarespace have gotten immensely popular in recent years. While it’s definitely a great tool for any non-coders who want to get a small website up and running quickly, managing content with a primarily visual interface can become a pain once you have more than […]
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]
