Solar Power: Vertical Axis Wind Turbine and wind Power
By: Gugu Maseko
There are two different types of wind turbine; Vertical and Horizontal. Each one performs their own function and have their own advantages and their disadvantages. You should pick the one that is best for you and your needs. They do have one thing in common and that is that they produce energy from winds. They just do it in a different way. Vertical axis turbine has the main rotor shaft running vertically instead of horizontally. This direction can have its advantages and disadvantages. The advantage is the gearbox can be put in the bottom of the turbine, unlike the horizontal turbines. All the weight is not at the top of the tower.
Giromill is a type of meal that features three vertical blades. It is self starting so the maintenance is low. These types of mills a low blade speed but they can create a high performance and success in channeling the energy from every turn of the blade.
Windstar Turbines has straight aluminum blades that are attached on each end of the rotating shaft. This windmill features more than one rotor and they each have their own dual braking system that has pneumatic disc brakes. They are designed for strong powerful winds.
The role of wind power
Horizontal axis wind turbines are the most use wind turbines. When you see these turbines in the field you may think that they are no longer helpful but there are several people who believe in using them still. Horizontal axis wind turbines can either turn upward or downward. If they choose to turn the blades upward, they don't hold good together for longer periods of time. They begin to crack and breakdown in high winds. When the blades are downward facing they stay in line with the wind longer and they can outlast through the high winds without breaking. Because they are so durable it keeps the cost down as well.
Windmills Consists of four or more blades, usually short, and can wooden blades. These were used to grind grain. As the winds picked up it would rotate a mechanism inside allowing it to run the grain through a mill crushing it.
The advantages of this type of wind turbine include stability, tallness, bendable, durable and strong. The disadvantages my include cannot operate well close to the ground, hard to transport over sea, difficult to install, not in big demand, there are concerns with how they affect radar, structural damage done with storms and wear.
