Has anybody built a cycle-generator for use on a sailing boat? I can produce
about 150W at steady state and up to 400W in bursts on a training bike, so I
figure if I built a small cycle-generator for my boat I could produce a
useful amount of amphours in an hour or so and keep in cycling shape too
while on my boat. Anybody built one? What could I use for the generator -
would a motor out of a car windscreen wiper assembly be suitable?

I know just what you are looking for it is called a Gibson Girl, strap
it to your legs and turn the crank. The Gibson Girl was carried on
over water flights fifty years ago. This waterproof unit was a 6 to 24
volt generator and transmitter.
