The human-powered helicopter probably doesn’t look like what you’d expect. It doesn’t resemble a typical helicopter at all. In fact, it looks like it’s built using K’NEX. They actually used carbon fiber tubing, styrofoam and a lot of superglue — so, it’s not too far off.

Looking at it, you’d think this helicopter must weigh a ton, but it clocks in right at 80 pounds despite its 100-foot diameter. Regardless, that’s a massive structure to get off the ground when we’re talking about it being powered by a person capable of generating 0.7 horsepower.

Despite the odds being against them, these engineering students take on the challenge and manage to successfully get it airborne. Even with their success, we don’t think you’ll be seeing one of these flying by anytime soon — or ever.
