In fact the generator is an hydraulic wheel which precedes the boat, and some of the energy captured from the wheel reduces the speed of the water which the boat encounters. Since the resistence of the water is proportional to the cube of the speed, this reduction of speed is significative and yelds to an efficience over the 100 %

Abstract

We iipotize a marine cycle of six hours of sailng and of two periods of half an hour each of navigation under propuslion of an engine ot exit and to enter an harbour. Along the period of sailing an electric generator can convert kinetic energy into electricity, say 2 KW for a 35 feet boat and store it into batteries. Exiting and entering the harbour an electric propeller of say 10 KW. A prototype of 0,5 KW generator si presented. It is modular and four modules can perform as above. Some experiences are under development to test the overall viability of the process. Some evidencies show an efficience over the 100%. More energy is stored than the one which is subtracted from the navigation speed. In fact the generator is an hydraulic wheel which precedes the boat, and some of the energy captured from the wheel reduces the speed of the water which the boat encounters. Since the resistence of the water is proportional to the cube of the speed, this reduction of speed is significative and yelds to an efficience over the 100 %
