Since all the OP wants is some lights in the "pool"
how about a different approach. Small DC motors make
good generators. Perhaps they would work better at
low speeds and low power than a fairly large car alternator.
I recently saw some plans were a guy made his own alternator
for a direct drive wind generator so that he didn't need any
gears or chains to increase the rotor speed to make the
generator work.
