Abstract
A power generating bearing assembly comprising a bearing retained by a bearing housing is provided. The bearing housing includes a bearing cooling passage system comprising at least one integrated liquid cooling passage is integrated within the bearing housing. A turbine assembly is inserted within the integrated liquid cooling passage, wherein fluid flowing within the integrated liquid cooling passage causes a turbine blade subassembly within the turbine assembly to rotate. The rotation of the turbine blade subassembly rotates an electrical power generator to create electrical power. The turbine assembly can be integrated into any existing bearing assembly comprising a bearing cooling passage system. It is preferred to seat the turbine assembly within a cooling system port of the bearing cooling passage system.
