  • Power generation device and a power generation method
    Patent number: 10924036
    Abstract: The invention provides a power generation device comprising at least two generating arrangements, each adapted to generate a voltage output through the relative motion of two differently charged generating elements, the generating elements having some separation distance (which may be zero or non-zero). The arrangements are co-operatively configured in such a way that the separation distances between their respective elements are reciprocally related: an increase in one leads to a related decrease in the other. By combining these two signal outputs, a single voltage, current or power output may be provided in a self-regulating manner by the device whose amplitude is substantially independent of any changes or variations in the separation distance between elements of either of the two arrangements.
