1. A portable electric power generator that converts linear mechanical motion into electric power, said portable generator comprising:

  • a base;

    an actuating member that is moveable between a stop position that is relatively away from the base and a compressed position that is relatively toward the base;

    a biasing member that links the actuating member to the base and that biases the actuating member toward the stop position;

    a drive link that travels in a direction that is generally orthogonal to the direction of movement of said actuating member;

    at least one electrical generator;

    a mechanical linkage that connects said drive link to said generator and that activates said generator in response to the travel of said drive link from a first position to a second position; and

    a storage battery that is electrically connected to said generator and that stores electrical energy in response to the activation of said generator.
