Human-Powered Helicopter


(Video Link)


Students at the University of Maryland build a functional helicopter that is powered only by human exertion:

The X-shaped helicopter, called Gamera, has 42-foot diameter rotors at each end of 60-foot long crossbars. A pilot's module is suspended from the middle, where Wexler, a biology student, sat and pedaled with feet and hands. Pilot included, the contraption weighs just over 200 pounds.


Judy Wexler pedaled hard enough to lift the craft (just barely) off the ground for four seconds. Skip ahead to three minutes into the video to see the flight.

Lol, Every one of the guys working it checked out her butt as she prepared to get in, and did anyone notice the epicbeard dude lying in the background looking all like gandalf?

Ray, du hast recht! Notice that the blades are next to the floor, below the center of gravity. This is an unstable design and was likely done to maximize the ground effect.

Cool, but I don't think you can consider it flight unless it leaves ground effect. The Spruce Goose had the same limitation on its only (attempted) flight.

this kid is fabulous, and even worried about what she's wearing...hilarious....and I can tell you there are grown ups that don't remember to get the dog settled

Sure, she did very well, but I don't think it lives up to its billing. I feel mislead into thinking there would be much more than a girl more or less simply staying on the line for six minutes.

Leave this sentence out "You won’t regret listening for six minutes to hear what Savannah had to say." and I wouldn't have listened nor bothered to comment here.

What a brave and amazing little girl -- I've still got tears in my eyes. Kudos to the parents for doing such a great job in raising her -- and kudos to the dispatcher for treating Savannah with the same respect he would have given an adult.

Hey Lol I would love to be standing in front of you when you make that comment about a child. I bet it would be the last time you ever thought about saying something so perverted about a child. And Michael get a life you pathetic loser.
