Wind power generator

Airdolphin is the name of a cute wind power generator.  Airdolphin is compact, light and simple no-screw body structure inspired by traditional Japanese handcraft techniques, the supplier, Zephyr says.   


The core rotor has three ultra-light carbon fibre blades that are uniquely designed dramatically to reduce air flow noise.   The robust body generator cuts in at a wind speed of 2.5m/s and cuts out at a 50m/s, while a windload survival rating is 65m/s.  A rated power figure is 1kw at 12.5m/s wind speed.
