Abstract:
1. A method of generating electricity, comprising a. providing a primary system in which a fan generated flow of air is produced in a conduit of the primary system in connection with a primary function that is other than the generation of electricity, where the method is practiced in a building in which the air flow produced in connection with the primary function is produced by one or more devices that regulate air flow in the building, b. locating a fluid driven turbine in the path of the flow of air, the turbine having turbine blades rotatable about an axis of rotation, the turbine blades located in the path of the air flow, and the axis of rotation of the turbine oriented transverse to the flow of air, to rotate the turbine from the flow of air in the primary system, and generating electricity from the rotation of the turbine.
