Claim 3:
4. A method of using capacitive storage to provide adjustable electrical potential output, the method comprising:
providing a capacitor with distance-movable plates, in which first and second capacitor plates maintain a parallel and opposed relationship, with a variable separation distance between the capacitor plates, and maintain the first and second capacitive plates in the parallel and opposed relationship, while permitting the separation of the first and second capacitive plates to change;
providing a drive mechanism to vary the separation distance between the first and second capacitive plates with the first and second capacitive plates maintained in a parallel and opposed relationship to form a capacitor by forcing electrical insulating oil between the two plates, the drive mechanism comprising an hydraulic pump,
whereby an increase in the separation distance renders a decreased capacitance, such that, with the capacitive plates charged relative to each other, the increase in separation renders an increase in potential across the capacitive plates; and
providing current transfer to and from the capacitor in a forward mode in an initial charge to the capacitor using a bidirectional DC-DC voltage converter which, in the forward mode, the bidirectional DC-DC voltage converter provides current to charge the capacitor to provide the initial charge to the capacitor, and in an output mode, discharge the capacitor,
wherein by providing the initial charge to the capacitor at a first separation distance, the increase in the separation distance provides the increase in potential across the capacitive plates, and in the output mode, the current transfer outputs potential from the capacitor at the increased potential, thereby increasing the output potential of the capacitor in the output mode.
