Resonance Wing

This would be a human powered ornithopter with bouncy weighted wings.

The wings could be made bigger because of the weights (maybe at the tips), and a resonance could be set up.

You would probably have to start this project off working only in still air and then prototype up to something sturdier.

       The weights wouldn't add energy, only store it, and at a much higher weight cost than other methods.

       [+] Might work without the human.

       Not too bad. When you think about it the weights would act like 'insect halteres'. If actually made like halteres, two could be rotated around the body of the craft. Not sure about the human powered bit though.

       I like this as an adjunct to a conventional Hoppity Hop riding balloon, or possibly Rody. The idea being that the energy stored on prior hops makes increasingly high and long hops possible. I suspect that there would be a point of diminishing return, though. Maybe not.

       Material science would have to come to the party with a very light and strong material that enjoys the bounce.

       Oh, my mistake, I must fetch my reading glasses.
