Patent ID: 7969035

Claim:
An apparatus for generating electricity from relatively low velocity exhaust gas produced by a piece of machinery, said piece of machinery includes an exhaust port through which exhaust gas is expelled, said apparatus includes: a. a fan assembly mounted adjacent to the exhaust port through which exhaust gas from a piece of machinery is expelled, said fan assembly includes two rotating discs with a plurality of fixed vanes coaxially aligned inside said fan assembly; and, b. a low RPM generator that includes a cylindrical outer housing attached to at least one said rotating side plate on said fan assembly, said generator includes a center axle with a stationary stator disc aligned therewith, said stator disc including a plurality of coil members radially aligned and embedded therein, said coil members being serially connected together with wires that extend into said center axle, said generator also including two magnetic discs located inside said outer housing and coaxially aligned with said stator disc, each said magnetic disc having a plurality of magnets mounted on its inside surface, said magnets on said magnetic disc having opposite polarities so that when said fan assembly rotates, an electric current is produced in said stator disc.
