  • Windmill - Wikipedia

    A windmill is a structure that converts wind power into rotational energy by means of vanes called sails or blades, specifically to mill grain (), but the term is also extended to windpumps, wind turbines and other applications. The term wind engine is sometimes used to describe such devices.. Windmills were used throughout the high medieval and early modern periods; the …

    The 4N-55 is designed & manufactured in the UK. The 4N-55 does not require sensors or motors to position itself into the wind, thus negating the need for complex control gear, eliminating a major cause of both horizontal and vertical axis wind turbine failure. The 4N-55 is self-starting. The 4N-55 has regen speed control in high winds and does ...
