Title:
WINDMILL/WATERWHEEL EQUIPMENT AND METHOD FOR UTILIZING EVEN FLOW OF UPPER SURFACE
Document Type and Number:
WIPO Patent Application WO/2005/010357
Kind Code:
A1
Abstract:
Equipment and a method for increasing the energy efficiency of windmill/waterwheel equipment which does not consume fossil fuel and accordingly never produce CO2 and has a priority over global environment since the equipment uses a renewable energy, wherein a flow on the upper surface of the equipment which has not been noted at all is also utilized. The embodiments for this idea are a drum container windmill shown in Fig. 5, a turbo fan windmill shown in Fig. 6, and a turbine windmill shown in Fig. 7. Equipment and a method for realizing a wind collecting and accelerating structure by generating separated swirl to increase an efficiency in windmill/water wheel equipment, the equipment wherein a turbine windmill with the wind collecting and accelerating structure shown by the embodiment in Fig. 14 is operated under operating conditions in a wide wind velocity range not found in a propeller windmill, develops no noise, and allows a protective net to be mounted for preventing men and domestic animals from being killed.
