Linear motion electric power generator
First Claim
1. A linear motion electric power generator for generation electric current from work done by an intermittent force comprising:
- A) at least one moving magnet;
B) a confinement means for confining within a confinement space but permitting said at least one moving magnet to move with a bi-directional linear, or approximately linear, motion within said confinement space;
C) at least two coils, each of said two coils surrounding said confinement space, one of said at least two coils, defining a first coil, being spaced apart from another of said at least two coils, defining a second coil, and said first and said second coils being connected electrically so that current produced in said first coil as a result of movement of said at least one moving magnet is substantially in phase with current produced in said second coil as a result of the movement of said at least one moving magnet as said at least one moving magnet passes successively at least partially through said at least two coils.

Abstract
A linear motion electric power generator for generating electric current from work done by an intermittent force. A moving magnet is confined so that it can move with bi-directional linear, or approximately linear, motion through each of at least two coils. 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. Preferred embodiments are described for providing electric power generation from extremely lower power mechanical forces. Embodiments of the invention 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 from repetitive forces such as the forces on the heel of a shoe during walking or running.
