WIND, SOLAR AND RAIN HARVESTER

摘要

A proposed wind, solar and rain harvester is described. The hybrid wind harvester (10) comprises a power-augmentation-guide-vane (12) and a wind turbine (14) sharing a centre axis as the guide vane. The novel power-augmentation-guide-vane (11) has an upper wall duct (22) and lower wall duct (24) inclined at an angle of 2 degrees to 75 degrees from the horizontal plane. The power-augmentation-guide- vane creates a venturi effect to increase the speed of wind entering the wind turbine to harvest more wind energy. A solar panel or solar concentrator is provided on top of the upper wall duct. A rain water passage and storage compartment is provided where rain water flows form the upper wall duct towards the rain water passage and storage compartment.
