People often dreamed of a small device that can be installed on the roof of a house which could provide all the needed energy. However, it was limited by their ignorance of the technology. Below we have put together a number of interesting facts about wind. What is a wind turbine? The proper name of a wind turbine is actually "Wind Energy Converter" ??a device that converts the potential wind energy to another form of energy. This can be either mechanical or electrical. How does the wind turbine work? When the wind blows, the rotor blade stops a percentage of the wind and this percentage is converted into energy. According to physics, the maximum amount of wind energy that can be converted is 59.3%. This is known as the Betz Limit. There are lots of different designs, which is the best? There are a number of types of wind turbines. The most wind generator common designs include: Research has been done on virtually every possible concept with the objective of producing the maximum amount of power for the lowest cost at the highest possible reliability. Conventional experimentation has found that the horizontal axis upwind or down wind design to be the best concept. As for vertical axis, it is great for very low wind areas, in medium or higher wind areas, its capabilities to produce energy are limited. With an eye to the practicality, Hummer wind turbine adopt the design of horizontal axis upwind. Related Questions: |
