We’re not sure why you’d want this Air Umbrella instead of a regular umbrella, other than to maybe feel like you’re living in the future. See, it basically replaces the canopy with a circular curtain of air that blows the raindrops clear out of the way. The large shaft contains a battery, while the dome has both an impeller and propeller, drawing air in only to blow it back out with force. Depending on the model, the battery should last between 15 and 30 minutes, and the entire thing weighs between 500g and 800g. So, yeah, you’re looking at a heavy umbrella that can protect you from the rain for 30 minutes at most. Oh, and it’s expensive too, with models becoming available with a $118 pledge. That’s a lot of things working against it, but hey, you pair this with some Back To The Future shoes and you can legitimately go around pretending you just traveled back in time.
