  • epoxy

    wind turbine composites. epoxy resins are used as bonding matrix along with glass or carbon fiber fabrics to produce composites with very high strength to weight characteristics, allowing longer and more efficient rotor blades to be produced.

  • houses at auvers

    houses at auvers is an oil painting by vincent van gogh, painted towards the end of may or beginning of june 1890, shortly after he had moved to auvers-sur-oise, a small town northwest of paris, france.. his move was prompted by his dissatisfaction with the boredom and monotony of asylum life at saint-rémy, as well as by his emergence as an artist of some renown following albert aurier's .

  • wind turbine

    the rotor, which is approximately 20% of the wind turbine cost, includes the blades for converting wind energy to low speed rotational energy. the generator, which is approximately 34% of the wind turbine cost, includes the electrical generator, the control electronics, and most likely a gearbox e.g.,.

  • offshore wind power

    offshore wind power or offshore wind energy is the use of wind farms constructed in bodies of water, usually in the ocean, to harvest wind energy to generate electricity. higher wind speeds are available offshore compared to on land, so offshore wind power’s electricity generation is higher per amount of capacity installed, and nimby opposition to construction is usually much weaker.

  • power tool

    energy sources. currently, an electric motor is the most popular choice to power stationary tools, though in the past they were powered by windmills, water wheels, and steam. some museums and hobbyists still maintain and operate stationary tools powered by these older power sources. portable electric tools may be either corded or battery-powered.

  • blade pitch

    blade pitch control is a feature of nearly all large modern horizontal-axis wind turbines. while operating, a wind turbine's control system adjusts the blade pitch to keep the rotor speed within operating limits as the wind speed changes.

  • diameter

    generalizations. the definitions given above are only valid for circles, spheres and convex shapes. however, they are special cases of a more general definition that is valid for any kind of n-dimensional convex or non-convex object, such as a hypercube or a set of scattered points. the diameter of a subset of a metric space is the least upper bound of the set of all distances between pairs of .
