One of the bits of technology in my book Nano-Plasm is "smart wings". The idea is that by changing the shape of a wing you can get much more efficiency than with a standard fixed-shape wing.
Here's some video of a Bumble Bee that shows how the Bumble Bee is able to fly in spite of the fact that according to "normal" flight equations his body weight is too great for his wing span.
This video was shot with the cool new digital high speed camera from Vision Research.
