Abstract
An industrial structure for wind energy harvesting includes an industrial housing requiring venting and a vent outlet, An industrial fan associated with the vent outlet evacuates exhaust, forming an exhaust flow zone opposite the vent outlet. The exhaust flow zone is defined by first and second boundaries extending from the industrial structure on first and second sides of the vent outlet. At least one wind turbine is positioned external to the vent outlet including a turbine blade portion and an electric generator. The at least one wind turbine is positioned with respect to the vent outlet such that during each rotational cycle, the blade portion is partially within the exhaust flow zone and partially outside the exhaust flow zone straddling the first boundary.

An industrial structure for wind energy harvesting, the structure comprising:
- an industrial housing requiring venting;
- a vent outlet in the industrial housing;
- at least one industrial fan within the industrial housing and associated with the vent outlet for evacuating exhaust from the industrial housing through the vent outlet and for forming an exhaust flow zone outside the industrial housing opposite the vent outlet, the exhaust flow zone being defined by a first boundary extending from the industrial structure on a first side of the vent outlet and a second boundary extending from the industrial structure on a second side of the vent outlet;
- and
- a first wind turbine positioned external to the vent outlet and including a first turbine blade portion and a first electric generator,
- wherein the first wind turbine is positioned with respect to the vent outlet such that during each rotational cycle of the first turbine blade portion, the first turbine blade portion of the first wind turbine is partially within the exhaust flow zone and partially outside the exhaust flow zone straddling the first boundary;
- and
- a second wind turbine positioned with respect to the vent outlet such that during each rotational cycle of a second turbine blade portion of the second wind turbine, the second turbine blade portion is partially within the exhaust flow zone and partially outside the exhaust flow zone straddling the second boundary.
