WindAge TDWG Systems Alternate Rotor Assemblies

When a piezoelectric crystal is suddenly bent, as in a disposable lighter, it produces electricity. This electricity can be captured on an overpass by flexible TDWG ducting--when it is slightly bent by a blast of turbulent vehicle air--so that it does not adversely influence the rotor’s smooth movement. This “bleed” energy can go into an auxiliary battery and then to a small DC motor, to keep the rotor always nominally turning in typically low-ambient-wind environments.
