Abstract
A rotor blade is used in combination with a submersible electrical generator for generating electricity to be put into the grid, where the pitch of the rotor blade is controlled by a microprocessor. The microprocessor controls a radio frequency transmitter which emits signals to a receiver which controls a hydraulic value. The hydraulic valve controls a push-pull arrangement which through a right angle gear and pitch adjustment axial adjust the rotor pitch according to pre-programmed conditions stored in the microprocessor.
