On Wind power - Literature review Example ; (3) the power in the wind is proportional to the density of the air (Park, 1982). According to history, the practical use of wind power began with the Egyptians around 2800 BC when slaves were made to row overseas using sails which were further employed in lifting water and operating grain-grinding stones even to within the period when Persians built panemones or vertical-shaft windmills in 700 AD. Some other civilizations of the Middle East followed the same tradition whereas the Crusaders of the West are believed to have improved the windmill concept that led the Dutch to put up propeller-type windmills structured with horizontal shafts or axes of propulsion. Technical developments continued during the Middle Ages and comparative studies show aspects of similarity among windmills founded in British colonies, New England, and Holland which altogether bore significant impact in the construction of the widely known ‘American Farm Windmill’ which was invented by Daniel H alliday who, in the mid-19th century, thought of creating a multi-bladed (Panemone Bladed Rotor Wind Energy Harvester with 8 Airfoils) windmill. At the turn of the century, wind-produced electricity as well as wind-charger technology became popular, especially to the farmers of the Great Plains who necessitated up to 1,000 Watts of DC-power in their mechanically run farming tasks. Eventually, a number of countries in Europe were inspired to create wind generators of enormous size and both the French and the Germans attempted to conduct feasibility experimentation on 100-kW and 300-kW wind generator units in the 50s and the 60s. Through the years, the continuous process of harnessing wind power made possible not only D. Halliday’s multi-bladed craft but even the succeeding advancements in the iron water-pump industry which heightened the demand for wind-powered deep well pumps in the past. While the energy derived from the wind had been discovered with other chief potentials a s in heating houses and barns, running sawmills and washing machines, several Midwest farmers who already possessed gasoline or kerosene generators to charge batteries still sought the aid of wind power in minimizing troubles with wear-and-tear generators and in reducing costs of fuels used. Such capacities, however, depend upon the quantities of wind power in acquisition. In his findings, P.C. Putnam illustrates a method to approximate the amount of power which can be extracted from the wind and the means to locate wind power with considerations to the periodic fluctuations in wind power as well as its reliability and short-term predictability. The author regards the concepts of kinetics hereafter necessarily pointing out that, like the kinetic energy of any particle, the kinetic energy of the wind may be computed via half of its mass multiplied by the square of the wind velocity and in terms of the volume V of air passing over an area A per unit time, the wind’s kinetic ene rgy equals the product between wind density and (1/2)*AV 3.
