Korean designers Je Sung Park and Woo Jung Kwon have developed an invisible umbrella that will keep you dry by repelling rain. Consisting of a simple plastic stick that creates an artificial wind at the top, the ‘umbrella’ deflects raindrops before they hit you by sucking in air at the bottom. The intensity of this wind-shield can be varied depending on weather condition and number of people sharing the device—the length of the stick is also adjustable.
so it’s basically a force field
and it makes people more convenient
How could the air be shooting out of that tube hard enough to create a shield? The motor in that thing would have to have tremendous thrust, and therefore substantial energy consumption. Kind of not as eco friendly as the plastic bag. But I want this to work, dammit! Force fields are badass, even if they are weak rain fields.
