These are early bird prices, but once it hits the market, the average price of an air umbrella is expected to be about $200. The Air Umbrella consists of three ‘sections’ – a motor near the head, a lithium battery at the center, and an controller with a switch at the bottom. According to their demo video, the product will be available in three variants – a ($88), b ($98), and c($108). Then the airflow forms an umbrella without a visible cover.” So when we make use of the airflow, we can protect ourselves from the rain drops. “The jet airflow can isolate some objects. The faster the air moves, the greater the energy is,” the engineers explained on the Kickstarter page. The flowing air can change the moving path of the object. The product is the brainchild of a group of graduates from Nanjing University of Aeronautics and Astronautics – they’ve set up a Kickstarter campaign to raise funds, and they’ve already collected $60,0000, exceeding their target of $10,000 with seven days to go. It does sound super-cool to be able to deflect the rain with blasts of air, creating the illusion of an invisible umbrella. Well, looking past that tiny flaw, you’d have to agree that the Air Umbrella is an ingenious invention. So you’d probably want to use it only if you’re confident you can get out of the rain in 30 minutes or less. In true Cinderella style, the ‘magic’ wears off at the stroke of the 30th minute – the umbrella stops producing air and you’ll be drenched in no time at all. For the experiment though, you’ll be needing an umbrella stick and I’m not going into my lawn to fuel up my curiosity.There is a small catch, of course – the device works only for a short while. Yes, you’ll be needing that for the ratio of the radius that is covering the man. Just hitting up next, is the volumetric flow rate. In the next part, the airflow should be faster, getting you into some more power and velocity calculations.
Now, who loves maths enough to start playing with numbers rather than enjoying the rain! And whoo, wait! Who on earth will actually find the radius of the raindrops falling? The bad news is, you have to find the figures, to make your own handheld air umbrella. Going into the calculations, we’ll be needing the terminal velocity of the raindrops.
If you have a knack of engineering or a technical mind somehow, the question clicking your mind would be the presence of an equally heavy motor that enables you to generate the airflow, and how can the weight be made withstanding on an umbrella? How inconvenient would that be? To push the rainĪctually away, you need a huge airflow at the top of your umbrella, to overcome So it createsĪn invisible air shield and saves you from getting wet. Revolves around deflecting the rain coming over the person holding it. Lab’, reciprocates the idea in designing an air umbrella on his own. Reach completion and the initial funds got distributed. It was successful enough to make $102,000. You might know of the Kickstarter project of air umbrella, Umbrella, without holding an umbrella, sounds insane! Here, we’ll share with you an interesting way to have an
#Kickstarter air umbrella free#
Do you have a unique perspective of seeing at things? Or ever wondered if you can stay free from the rain without the effort of carrying an umbrella? Is that even possible to make rain repel you? Untangling your neurons?
