Human Powered Flapping Flight
Here are some ideas about human-powered flight. A closed cell foam wing suit, tapered evenly in thickness and rigidity would spread the force evenly across the most air possible, so all of the body's energy could be put to use.
Here's a list of keywords and concepts:
1. Vertical take-off
2. Undulating or flapping flight. Stroke like the swimmers "crawl" or "doggy paddle"
3. Super light and springy foam, sandwich layered for low internal density.
4. Leg wings, tail wing or whole body fin (like a ray)
5. "S"-curve cross section of wing, with leading edge down.
6. Corkskrew - Spring wings. Model these by twisting a metal band into a cornucopia-screw and putting it inside a balloon. Wings should be shaped like a feather -- curved down on the leading edge and up on the trailing edge and the spine should spiral either right or left handed depending on the side of the body.
