Energy generation system and method

A method, comprising

• providing an electrical power generator for generating electrical power, the electrical power generator comprising:
• a first element and a second element at least one of which comprising an electrical charge, wherein one or both of the first and second elements comprises:
• a planar surface comprising grooves or radially spaced rotor blade elements for generating a fluid-dynamic force between the first element and the second element in response to a relative speed of rotation, the first and second element being further configured to be rotatable with respect to each other in order to thereby generate the electrical power when at least one of the first element and second element comprises the electrical charge;
• rotating the first element and the second element with respect to each other;
• and
• controlling a distance between the first element and the second element by controlling a relative speed of rotation between the first element and the second element.
