Patent ID: 7987665

Claim:
An apparatus for evacuating exhaust from an exhaust pipe of a vehicle, comprising: an external turbine having a tubular base with a plurality of blades extending outwardly therefrom, the base being rotatable about the exhaust pipe, the external turbine further having a hub connected to the base so that the hub is in a co-axial relationship with the base; an internal turbine connected to the external turbine such that when the external turbine rotates the internal turbine rotates, the internal turbine comprising: a hub; a plurality of blades extending radially from the hub; and a shaft having one end connected to the hub of the internal turbine and another end connected to the hub of the external turbine; and a support member connected to at least one of the external turbine and the internal turbine and connectable to at least a portion of the exhaust pipe of the vehicle such that the external turbine is positioned on an exterior side of the exhaust pipe when the internal turbine is positioned in the exhaust pipe and such that when the vehicle is in forward motion, air flow over the external turbine causes the external turbine to rotate and thereby causes the internal turbine to rotate to cause exhaust of the vehicle to be extracted from the exhaust pipe.
