There was the solar-powered Booster Brolly, the windproof Rainshader and the lopsided Rain Shield, just to name a few. But now a team of Chinese designers is looking to do away with the awkward metal poles and canopy entirely, relying instead on a "force field" of air to keep you nice and dry.
The idea of using air flow to shield users from pelting rain has been explored before. A pair of designers developed a similar concept back in 2010, though this version seemingly never made it to market.
The latest take on the Air umbrella uses a lithium battery to power a motor and fan, which creates a cycle of air flowing through its tip to deflect the drops and form the protective layer.
