An apparatus for generating electricity from a relatively low velocity exhaust produced by a piece of machinery. The apparatus includes a fan assembly located inside a frame mounted adjacent to the exhaust vent found on the piece of machinery. The fan assembly includes a plurality of fixed vanes that extend transversely into the exhaust gas. The ends of the vanes are attached to two side plates that rotate freely around the frame's center axis. Attached to the inside side plate is an outer housing with two magnetic plates mounted therein. The two magnetic plates are spaced apart thereby forming a gap in which a stator disc with a plurality of coil members is formed. The stator disc is fixed to an axle that is longitudinally aligned with the center axis of the outer housing and the fan assembly. During operation, the exhaust gas causes the fan assembly and the outer housing to rotate. Because the stator disc is stationary, an electric current is produced in the stator disc as the two magnetic discs rotate around it. The current is then transmitted to a rectifier and inverter for local use or transmission to a utility grid.
