Turbine powered by exhaust fan

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
• at least one wind turbine positioned external to the vent outlet and including a turbine blade portion and an electric generator,
• wherein the at least one wind turbine is positioned with respect to the vent outlet such that during each rotational cycle, the blade portion of the at least one wind turbine is partially within the exhaust flow zone and partially outside the exhaust flow zone straddling the first boundary.
