Power generation device and a power generation method

A power generation method, comprising:

• operating an electrical power generator, the generator comprising a first generating arrangement and a second generating arrangement,
• wherein each generating arrangement is arranged to generate an output voltage and an output current,
• wherein each generating arrangement uses first generating element and a second generating element, at least one of the first generating element and the second generating element is arranged to have a state of charging,
• wherein the first generating arrangement is arranged to be moveable with respect to the second generating arrangement,
• wherein a movement of the first generating arrangement relative to the second generating arrangement generates an output voltage and an output current,
• wherein the output voltage and/or current is dependent upon a separation distance between the first generating element and the second generating element of each generating arrangement,
• wherein, the generating arrangements are arranged such that an increase in the separation distance between generating elements of the first arrangement results in a related decrease in the separation distance between generating elements of the second arrangement, and vice versa, the method comprising:
• inducing relative motion between the first generating element and the second generating element used by each of the first generating arrangement and the second generating arrangement, wherein each of the first generating arrangement and the second generating arrangement generates the respective output voltage and the output current;
• and
• combining the output voltages and the output currents of the first generating arrangement and the second generating arrangement.
