Embodiments of the present disclosure are directed to an energy recovery system for a heating, ventilation, and/or air conditioning (HVAC) system. The energy recovery system includes a nozzle having a flow passage with an inlet passage and an outlet passage that is narrowed relative to the inlet passage, in which the nozzle is configured to couple to a condenser and receive an air flow into the flow passage from a condenser fan. The energy recovery system further includes a wind turbine disposed within the outlet passage of the flow passage and having a first axis of rotation, and a generator that is external to the nozzle and that includes a shaft with a second axis of rotation. The generator is coupled to the wind turbine, such that the first axis of rotation is aligned with the second axis of rotation.

A system for harvesting energy from airport vehicle and passenger movements is described that includes a vehicular operating area with an operating surface, a pedestrian movement area with a walking surface, a first plurality of vibration panels positioned within the operating surface of the vehicular operating area, a second plurality of vibration panels positioned within the walking surface of the pedestrian movement area, and an electricity distribution grid. Each vibration panel in the first plurality of vibration panels and each vibration panel in the second plurality of vibration panels is a piezoelectric transducer, and each piezoelectric transducer is coupled to the electricity distribution grid such that electricity produced by each piezoelectric transducer in response to vibrations from vehicle or passenger movements is routed to the electricity distribution grid.

A wind and water power generation system is presented. The wind and power generation system has a roof mounted gutter system with an internally integrated turbine. The internally integrated turbine has a connection to an externally positioned wind scope. Thus, the rain run-off causes the internal turbine to rotate to generate power and the external wind scope allows the internal turbine to turn without rain.
