<p>This invention relates to a collector rotor (10) and to a related airplane tyre (116.1). The collector rotor (10) is for harvesting energy from fluid flow, e.g. airflow or water flow. The rotor includes an arrangement of fluid flow barriers (16.1), typically flaps (20), around its rotational axis. The configuration of the barriers is such that, in use of the rotor, fluid flow transverse to the axis alternately forces each barrier into a first, high drag configuration when the barrier is displaced against fluid flow during rotation of the rotor and into a second, low drag configuration when the barrier is displaced along with the flow. The invention extends to a method of using the collector rotor for energy harvesting for electricity generation. The collector rotor may be provided as part of an airplane tyre (116.1) to provide for operatively rotationally accelerating the tyre for landing, upon being exposed to airflow.</p> |
