Regeneration will not provide for
all needs, except in limited cases. However, it is nice if it can supply a
substantial part of the use.


even at the cost of 5 hp pushing backwards on the boat as you sail?

it seems to me to be a damned expensive way to move a boat. why not buy a
little Honda generator and drag a 55-gallon drum behind the boat. same net
effect, and cheaper, too.
