Je Sung Park designed an interesting concept he calls the invisible air umbrella.

Instead of a material canopy, the invisible umbrella utilizes the force of air to deflect raindrops and keep you dry. A radial current of air is blown from the top of the hollow pipe. As it rains harder, the force of the air curtain can be increased.

The invisible air umbrella is still only theoretical and is not yet for sale. No surprise. As sexy as this idea may be at first blush, I don’t think a couple of AA batteries could effectly repel a thunder shower. Then when your batteries went dead, or got wet, you’d look like a crazed baton twirler getting soaked.

Final thought…I love how this inventor claims this battery hog is more eco friendly than a plastic bag. How does it’s carbon footprint compare to, I don’t know…a normal umbrella?
