1. An energy recovery system comprising:
- a ventilation system of a defined area, the ventilation system having at least one exhaust wherein air from within the defined area is expelled outward of the defined area by at least one exhaust fan as an exhaust air flow that flows out of the at least one exhaust;
at least one windmill located exterior to the defined area and being a selected distance from the at least one exhaust,at least one flow guide apparatus positioned between the at least one exhaust and the at least one windmill, the at least one flow guide apparatus comprised of a body having a first side and a second side and a plurality of guide vanes, each guide vane having a proximate end attached to the body and a distal end that extends away from the body;
wherein each windmill is comprised of;
a rotatable shaft,a plurality of vanes connected to the rotatable shaft such that rotation of the vanes causes the rotatable shaft to rotate, andan electrical generator connected to the rotatable shaft such that rotation of the rotatable shaft causes electricity to be generated,wherein the plurality of vanes are configured to rotate when the exhaust air flow flows on the vanes.

Abstract
An energy recovery system includes a ventilation system of a defined area, at least one windmill located exterior to the defined area and at least one flow guide apparatus positioned between the at least one exhaust and the at least one windmill. The ventilation system has at least one exhaust from which air from within the defined area is expelled out of the defined area by an exhaust fan as an exhaust air flow. The one or more flow guide apparatuses are positioned between the exhaust and the one or more windmills and are preferably sized and configured to redirect at least a portion of the exhaust air flow into an axial flow that moves toward one or more of the windmills.
