<p>A linear motion electric power generator for generating electric current from work done by an intermittent force. A moving magnet (2) is confined so that it can move with bi-directional linear, or approximately linear, motion through each of at least two coils (5 and 6). The coils are spaced apart from each other and connected electrically so that current produced in a first coil as a result of movement of the moving magnet is substantially in phase with current produced in said second coil. Embodiments of the invention provide pwoer from extremely low power mechanical forces and are useful for providing power for long life flashlights, for alarm systems and for communication devices located at places where conventional electric power sources are unavailable. Another preferred embodiment is a low profile unit which derives its mechanical power from repetitive forces such as the forces on the heel of a shoe during walking or running.</p> |
