The air umbrella is a french student's design entry for the James Dyson Award. His reasons for getting rid of the fabric canopy are that the fabric gets wet and leaves puddles of water in your house while they are drying off, and conventional umbrellas can flip inside out in strong winds.
His futuristic umbrella design uses a miniaturized version of Dyson's Airblade technology to deflect rain directly overhead. The cane-shaped umbrella has a telescoping design that brings up the motor. Once extended, a ring can be twisted to switch on the motor and create the air dome that redirects the rain drops away from your head.
