    In the traditional EMG-based wind turbine with large current and strong stability, adding the part based on TENG can effectively utilize the energy of low wind speed and generate high voltage. Guo et al. designed a novel pinwheel that consisted of the TENG part and EMG part for harvesting air-current power, as displayed in Figure 3(a) . In the TENG part, there is a rotator with radial-arrayed copper sections as …

    2016-3-14 · We have chosen to manufacture a 4-blade HAWT in order to obtain a high rotational speed with low airflow speeds. Concerning the rotational part of the turbine, the diameter D is set to 40 mm. We have chosen to fix the depth of the turbine at W = 10 mm from the base of the wing to the wing tip to obtain a clean result with a material deposited by layers, as in the case of rapid prototyping (figure 7 (a)).
