Roger ,, the water generator are sold on the net. I talked to a fellow
sailor about one. He came across the Atlantic on a very large
sailing yacht and the water generator produced lots of power. He said they
would watch a movie every night while off watch.

He did tell me that the pull on a small boat would be a negative. And, he
said the water generator would not work near ports due to
lobster pots, etc.

Also,, he mentioned that fish are attracted to the generator and it can be
expensive when the thing gets eaten.

Tally ho.

The fellow who builds the Cape Horn wind vanes has a great DVD of his
circumnavigation. He had a stern pulpit mounted alternator with a prop
trailing on a line. It appears to have done a good job of supplying his
electrical needs since the boat didn't have an engine. This was in the
early 80's so it was probably just an automotive alternator.

A shark ate the trailing turbine and, after doing without power for a
while, he fabricated a new one from stuff he found on board. The
improvised rotor is beautiful and a testimony to what human ingeniuity can
do with minimal materials and tools.
