Which Is Better, Horizontal Axis Or Vertical Axis Windmills?
Several factors go into choosing the right windmill for your residence’s self-sustaining energy unit. You will have a better understanding of the various types of windmills under the categories of horizontal and vertical axis windmills in this article. There are many differences between horizontal and veritcal axis windmills which you will see.
First, do you know what wind turbines are? Windmills are rotating machines that take the energy gained from the wind and converts that energy into mechancial energy, which can be used a power source. Fundamentally, the wind causes the blades to rotate and that power is then able to be turned into electricity through a generator. Depending on the type of windmill constructed the generator is located in certain areas. Below will show what horizontal and vertical axis windmills exactly are.
Horizontal axis windmills are designed in a way that the blades need to be facing into the wind. The wind passing by the blades causes them to rotate and then creating that energy. The energy can cause the blades to spin over 200 mph! With some blades being more than 100 meters long they are spinning at 10-22 revolutions per minute! But, this only happens when the wind is hitting the blades head on. The main disadvantage of a horizontal axis windmill is the lack of adjustment. In order for the blades to turn, the windmill needs to be positioned in the winds path. But the wind doesn’t always come from one direction, which hinders the horizontal axis windmill from turning its blades on a constant basis.
Vertical axis windmills are designed in a different way as the generator is located on the ground versus horizontal axis windmills of being placed high up in the air. Vertical axis wind turbines have a main rotor shaft designed vertically. This is the main advantage over the horizontal axis windmill as it can produce energy from any wind direction. This is very important because the wind direction is extremely unpredictable.
There are numerous reasons why I would choose a vertical axis wind turbine over a horizontal axis windmill for my home powered wind turbine system. First, they are designed to be lower to the ground making it easy for repairs if needed. Next, they start creating electricity at speeds of only 6 mph. And third, they may be able to be built at locations where taller structures, such as the horizontal axis type, are not able to be built.
