Original Concept Video
The video shows the transfer mechanism which is underwater. The float need not rise to the surface to be effective; it will function even several meters below the surface as swells pass over it. The bearing at the pivot point is the most critical element; a similar idea with a pulley has been patented many times, but the problem there is that the cable will wear out after a brief period of passing back and forth through a pulley in a salt water and sand environment. By extending the front arm, one can also compensate for tidal variations — which was the primary idea of the 1998 U.S. patent already issued to the inventor. Oscillating horizontal motion of the line coming to shore can be maintained regardless of tidal variations.
