Thanks. That seems reasonable for well conditioned cyclists.

There are some interesting numbers at:
http://en.wikipedia.org/wiki/Human-powered_transport -- perhaps the salient
one here being that well-conditioned cyclists can produce ~200W for over an
hour, with short bursts burst 1500-2000W.

Human-powered aircraft require a continuous ~200-250W input -- that guy who
crossed the English Channel wasn't just a weekend rider. :-)

Interestingly, an ultra-lightweight single-man aircraft covered with solar
panels can generate a couple kilowatts when the sun is shining brightly.
