Its purpose is purely for sailing boats, as it produces electrical energy during sailing , when the boats engine is stationary, and the need for electrical energy does not change during sailing. Users, such as: instruments, radar, navigation equipment, radio transmitters and receivers, refrigirators, water pumps … they all have constant consumption of electrical energy, which needs to be replaced, otherwise the electricity in battery keeps lowering. We can replace it with occasionaly turning the engine on, which is wasteful, as the main drive for sailing boats is the sail or more sails….
The main concept is exploitation of kinetic energy of moving vessel and still water mass at vessel. The speed of vessel depends upon wind, the characteristics of vessel and the ability of the crew. Generator je designed to produce direct current (DC) at 12V, at speed of 4 knots and up but characteristics are limited with 14V and 55A (770W), which – theoretically is the maximum power of the generator. Rated power HG300 is 300W at speed 6,5 knots.
The main components are: chaplain elisa, angular power transfer from a horizontal position to a vertical position , hydrodynamic housing, generator 14V 55A, ventilated labyrinth lid of generator and mountings, which adjusts to the vessel. Total weight without the mountings is 12,5 kgs.
During sailing, HG300 is lowered into water, so that the turbine can do its job. Resistance which is produced of course lessens the speed of the vessel, however, the measured readings on prototype were between 0,1 and 0,2 knots, which is moderate, for production of 300W of electrical power. When the vessel is powered by motor, the HG is lifted out of the water (by hands), as at that time electricity is produced by built-in generator.
