Wind is a new energy with great potential, and in the beginning of the eighteenth century, one fierce and strong wind in two countries of English law is swept transversely, so that four hundred wind mills, eight hundred houses, one hundred churches and more than four hundred sailing boats are destroyed, thousands of people are injured, and twenty-fifty thousand big trees are uprooted. In the case of a tree pull alone, wind generates ten million horsepower (i.e., 750 ten thousand kilowatts; one horsepower equals 0.75 kilowatts) in a few seconds | it has been estimated that the wind resources available on earth to generate electricity are about 100 hundred million kilowatts, which is almost 10 times the amount of hydroelectric power generated worldwide. At present, the energy obtained by burning coal every year all over the world is only one third of the energy provided by wind power in one year. Therefore, great importance is attached to the utilization of wind power to generate electricity at home and abroad, and new energy is developed. Attempts to generate electricity from wind have been made as early as the early twentieth century.
