Abstract

An electric generator includes a base having an outer pole flux core supported on the base and having a linear bore extending thereinto. A plurality of permanent magnets are mounted to the outer pole along the interior of the linear bore. A center pole flux core extends into the linear bore of the outer pole flux core. A generator coil is formed on the coil support sleeve and slidably mounted over the center pole flux core in the outer pole flux core linear bore and extends from the outer pole linear bore. A float member is attached to the generator coil support sleeve for moving the support sleeve responsive to movement of the float movement whereby the electric generator produces electric power responsive to movement of the float when the float is positioned to float on an oscillated fluid, such as when the electric generator is mounted to a platform over ocean swells. The center pole flux core may also have a plurality of inner magnets mounted therearound and a pair of electric generators may be mounted adjacent each other so that a rocking float can be connected to two electric generator coil support sleeves for moving the support sleeves in the generator coil in an alternate motion with the rocking of the float.
