Abstract

A vertical wall barrier is sited adjacent to the blades of a marine turbine. The deflector is flat and diverts water to the turbine to increase speed and volume of water through the turbine in both opposing directions of tidal flow. The deflector is positioned in line with the turbine blades and at approximately right angles to the blade axles. The deflector can be built onto the sea bed in shallow water or floating and anchored to the sea bed in deep water. It is best used in coastal areas with quick flowing tides, eg. around headlands, in estuaries and in deep sea ocean currents. The deflector may be positioned vertically in line with the turbine and have a height equal to at least the turbine diameter. The width is preferably at least four times the turbine diameter.
