A friction limiting turbine gyroscope is a compact and efficient means to convert the energy of a moving fluid into electrical energy. The gyroscope's flywheel rotates when a fluid passes through its spokes while magnets located along the perimeter act upon proximate movable field coils to produce electricity. The spokes of the flywheel are optimized for the flow and density of the fluid with the ability to trans mutate using shaped memory alloys as well as rotate about their center of pressure allowing the flywheel to capture more of the energy from the fluid passing over their surfaces in all conditions. Mechanical energy losses are reduced because of the inherent stabilizing effects created by the gyroscope. Because of the stabilization, a magnetic bearing field effectively supports the gyroscope eliminating mechanical interference in rotation.

The disclosed technology provides a system and methods for transforming kinetic energy from wind and solar energy from sunlight into three phase electrical energy for local use and available to supply to electrical grids. The system includes a solar panel system and a wind system, which through a gearbox translates kinetic energy from the wind into hydraulic energy in a hydraulic circuit. One or more generators are coupled with the hydraulic circuit to translate the hydraulic energy into three phase electrical energy. In embodiments, a pump motor runs off of a rechargeable battery to supply hydraulic energy to one of the generators when the wind is insufficient to provide sufficient hydraulic energy to the generator. The rechargeable battery may be recharged by diverting energy from, for example, the solar panel system.
