1. A pneumatically driven electric power generator comprising:

  • a single cylinder having a first end connectable through a single inlet flowpath to an air supply passage containing air at a positive pressure, a second end of said cylinder being open;

    a cylinder extension at least one of formed integrally with and attached to said single cylinder, said cylinder extension having an inner surface having a transverse dimension greater than a transverse dimension of said single cylinder, said cylinder extension including a threaded portion adjacent one end thereof;

    an end closure threadably connected to an end of said cylinder extension;

    a single piston having a magnetic moment associated therewith, said piston being positionable in a first location wherein at least a first portion of said piston is disposed within said cylinder and in a second location wherein said first portion of said single piston is outside of said single cylinder so that clearance is provided between said single cylinder so that air may exhaust from said single cylinder;

    sealing means disposed on at least one of an outer surface of said first portion of said single piston and an inner surface of said mingle cylinder to prevent loss of air between said single piston and said single cylinder and permit air pressure in said single cylinder to increase when said first portion of said single piston is disposed within said single cylinder;

    a single biasing means caged between a ledge portion adjacent one end of said single piston and an inner surf ace of said end closure for moving said single piston from said second position toward said first position so that after said single cylinder has substantially exhausted, said single piston moves to said first position, whereby said single piston oscillates, moving back and forth between said first position and said second position, driven alternately by air supplied through such air supply passage to said single cylinder and by said biasing means; and

    at least one electric coil placed to enclose changing magnetic flux caused by said magnetic moment associated with said piston whereby an emf is generated in said electric coil, so that an external circuit connected to said electric coil receives electric power from said electric coil.
