ABSTRACT:
A wind turbine with hydro-transmission has a tank filled with circulating liquid, a generator disposed beside the tank, a water pump mounted at a top of a stand and multiple blades connected to the water pump. Wind rotates the blades to drive the water pump to draw the circulating liquid up and pouring the circulating liquid over the generator to generate electricity. The generator that needs more maintenance is disposed on the ground and the water pump that needs less maintenance is mounted at the top of the stand. Therefore, construction and maintenance costs as well as footprint of the wind turbine are reduced.
