People have been struggling with rain since we’ve been here, and somehow an umbrella is the best option we’ve come up with to keep it (mostly) dry. There must be a better solution, which Ivan Miranda has potentially created throwing more technology in trouble.
Yes, umbrellas are cheap and crumble so they are easy to wear, but they are also fragile i prone to decay when faced with the slightest breeze. And while they are good to store rain from the head, all that water dripping from the edge of the umbrella usually ends up somewhere else on your body. Umbrellas are actually nothing more than a repurposed palm leaf, and for a species it is successfully sending humans to the moon and robots to other planets, we seemingly have really given up on improving the way we stay dry in the rain.
Still, not all of us. Ivan Miranda is a talented producer who shares his creations – which include everything from a 3Dprinted tank they can actually climb inside and drive up an all-terrain skateboard– on theirs YouTube channel. For her upgraded umbrella, Miranda completely skips the idea of a collapsible canopy and instead focuses on creating a wearable device that manifests a disk of high-velocity air above their heads that repels raindrops as they fall.
Watching their entire creative process is as fun as the end product. Their first attempts involved 3Dprinting an impeller powered by an electric motor used for RC aircraft and which would push air outwards and from their heads when the setting was mounted on a helmet. However, 3D printing is an imperfect process, resulting in unbalanced impellers that vibrated so strongly that they actually affected Miranda’s vision while the device was strapped to her head.
The final solution was 3D tradingprinted impeller for pre-built (and perfectly balanced) duct fan assembly, which is often used to create high power RC aircraft jet engines. The air is sucked in through the vent fan opening on their head and directed down and out through a thin 360-degree exhaust vent. A powerful explosion from the fan blower does exactly what it was designed to do, creating an air curtain around Miranda that repels falling water (a garden hose was used for testing), but the solution comes with some trade-offs. Not only will everyone within a 10-foot radius of the Miranda feel the exhaust and be showered with bounced rain, but the turbine engine is incredibly loud when running at enough speed to keep up. rain away. You would go to the place where you went to dry, but instead of dealing with a wet umbrella when you got there, you would face tinnitus and potential hearing loss.
