ABSTRACT:
An electrical generator comprises a stationary permanent magnet for establishing a magnetic field, one or more sensing coils responsive to the magnetic field, and a diamagnetic blocking element movable between the magnet and the sensing coils for periodically interrupting the magnetic field to produce electrical energy in the coils. A preferred embodiment includes a pair of semi-circular coils arranged side-by-side in the magnetic field and a rotatable blocking disc interposed between the magnet and the coils. The disc includes a semi-circular portion of superconductive material rendered impermeable to the magnetic field at temperatures near absolute zero and a semi-circular portion of magnetically inert material to alternately block and pass the magnetic field to the coils upon rotation of the disc.
