Could a jet engine be the umbrella alternative we need?

People have been struggling with rain since we live, and somehow an umbrella is the best option we’ve come up with to keep (mostly) dry. There must be a better solution that Ivan Miranda potentially created throwing more technology in the problem.

Yes, umbrellas are cheap and foldable, so easy to carry around, but also fragile. and prone to decay at the slightest wind. And although they are good for keeping rain from your head, all this water dripping from the edge of the umbrella canopy usually ends up elsewhere on your body. Umbrellas are really nothing more than recycled palm leaf, and for species that successfully sent humans to the moon and robots to other planets, we seem to have really given up on improving how to stay dry in the rain.

But not all of us. Ivan Miranda is a talented producer who shares his creations including everything from 3D-printed tank they can actually climb inside and drive to all terrain skateboard-on their YouTube channel… For her redesigned umbrella, Miranda ditches the idea of ​​a folding canopy altogether. and instead focuses on creating a wearable device that exhibits a disc of high-speed air overhead that reflects raindrops how they fall.

Watching their entire creative process is just as interesting as watching the final product.… Their first attempts included 3Dan impeller seal, driven by an electric motor used for RC aircraft, which will push air outward and away from their head when the rig was mounted on the helmet. However, 3D printing is an imperfect process whereby the blades are unbalanced and vibrate so violently that they actually affect Miranda’s vision when the device is strapped to his head.

Ultimately the solution was to trade 3Dprinted impeller for a pre-engineered (and perfectly balanced) duct fan assembly that often used to build high power RC planes jet engines. Air is sucked in through the exhaust fan opening above the head and directed down and out through a thin 360 degree exhaust slot. The high-powered exhaust fan does exactly what it was designed to do, creating an air curtain around Miranda that diverts falling water (a garden hose was used for testing), but this solution has some tradeoffs. Not only will everyone within 10 feet of Miranda feel the exhaust and are caught in reflected rain, but the turbine engine is incredibly loud when it is running fast enough to maintain rain away. You will get to where you are going to dry out, but instead of having to deal with a wet umbrella, when you get there, you will be dealing with tinnitus and potential hearing loss.
