Potable Water - The Third Way.
Dear Wilbur Hubbard:
"Wilbur Hubbard" wrote in message anews.com... .... Lame suggestion and unworkable on most boats. Ya gotta think outta the box, man. However, there is another way. I thought it up all by my lonesome. All you need is a reverse osmosis membrane. You put it into a chamber that is vented to atmosphere on the inside and to the ocean on the outside of the membrane. You lower it into the ocean to a depth of only 500 feet and the pressure of the water is enough to push fresh water through the membrane into the chamber. When it gets full you haul it up and empty in into your tanks. Reverse osmosis without any energy used to get it. Ain't Wilbur brilliant? You are still displacing that much water... not a small feat.
