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.

Device for conversion of wave energy into electrical energy and the process for its deployment at the exploitation location, wherein the device comprises a supporting construction composed of buoyancy elements and having a supporting tube attached on the upper side. The device comprises a joint gear on the inner circumference connected with the outside surface of the supporting tube in a sliding manner and a sphere to which is the floating body pivotally connected. The device has two gears, the first flexible gear for connecting the floating body to the second gear and the second gear for connecting the flexible gear to the generator. The flexible gear consists of pulleys and a flexible element, e.g. a rope or a steel cable and the second gear can be arranged in several suitable forms, e.g. rigid elements as a set of a gear and a rack positioned inside the lower supporting tube or a flexible element, e.g. a chain and a sprocket wheel set in the buoyancy element. The supporting construction is by ropes connected to the anchor weight that is made in a form of a sphere segment either directly or through the rolling elements placed in the spherical dent of the anchor base. The invention comprises the process for device deployment at the exploitation location which is particularly suitable due to stable transport with low draught.

This invention discloses a significantly improved linear machine system used for massive energy storage with vertical movement of heavy mass placed in containers. It adopts distributed rotor or mover structure to minimize the fringing effect and thereby enhancing effective lifting force. It further adopts the pulse transitional current to those non-transitional rows of rotor or mover conductors when the transitional rotor or mover coils cross the boundary between the magnetic and non-magnetic layers of the stator.

A load adaptive linear electrical generator system is provided for generating DC electrical power. The electrical generation system includes one or more power generation modules which will be selectively turned on or off and additively contribute power depending on the DC power demand. Each power generating module includes a pair of linear electrical generators connected to respective ones of a pair of internal combustion piston based power assemblies. The piston in the internal combustion assembly is connected to a magnet in the linear electrical generator. The piston/magnet assembly oscillates in a simple harmonic motion at a frequency dependent on a power load of the electrical generator. A stroke limiter constrains the piston/magnet assembly motion to preset limits.

A linear generator for generating electrical power from momentum of a vehicle, comprises a moving part and a stator. The moving part is a powered vehicle moving along a defined path and the stator is built along the defined path.
