Abstract: A moving-air energy recovery system including an air horn having serially disposed segments of differing flare rates, which intercepts a large area of moving air to channel and transform the flow of moving air into a more concentrated, higher velocity of air flow. This higher velocity air flow is applied to turbine vanes which are connected to an armature that provides a mechanical energy output from the incident air flow on a rotating shaft. In one embodiment, the shaft is connected to a electric generator to generate electric power, which may be applied to stationary applications such as emergency home power, and to mobile applications such as augmenting automobile propulsion.
