Abstract
A power generating bearing assembly providing a bearing retained by a bearing housing. The bearing housing includes a bearing cooling passage system having at least one integrated liquid cooling passage integrated within the bearing housing. A turbine receiving bore is formed through the bearing housing, penetrating the integrated liquid cooling segment. A turbine assembly is inserted into the turbine receiving bore, positioning a turbine blade subassembly of the turbine assembly within the integrated liquid cooling passage, wherein fluid flowing within the integrated liquid cooling passage causes the blade subassembly to rotate. The rotation of the blade subassembly rotates an electric power generator to create electric power. The turbine assembly can include an electro-magnetic subassembly mounting plate, wherein the turbine subassembly is located on an interior surface of the mounting plate and at least a portion of the power generating portion located on an exterior portion of the mounting plate.
