Electrical generators for low-frequency and time-varying rocking and rotary motions

An apparatus for generating electrical energy from a first motion having a low and/or variable frequency, the apparatus comprising:

• a first device to which the first motion is transferred;
• and
• a second device to which the first motion is transferred from the first device, the second device operating at a frequency which is higher and/or more constant that the first motion;
• wherein the first device comprises one of a rotating shaft or translating mass;
• the shaft or mass includes at least one tip interacting with the second device to transfer the first motion thereto, the second device comprises a member having an electrical energy generator to generate electrical energy;
• and
• one or more magnets arranged on one or both of the at least one tip and member to create a magnetic attraction force between the at least one tip and member;
• wherein one of the at least one tip or member includes a first magnet and the other of the at least one tip or member includes second and third magnets, wherein north and south poles of the first, second and third magnets are arranged such that each of the north poles are attracted by a south pole and each of the south poles are attracted by a north pole when the first magnet interacts with the second and third magnets.
