Wind power
Wind energy is one of the most widely used sources in terms of renewable energy capacity (Çukurçayır and Sağır., 2007). The history of using wind energy dates back to very old times. The first examples of wind power are sailing ships and windmills. The kinetic energy of the wind was used for the movement of the ships in the sailing ships and the wind power was used in the windmills to grind cereals such as wheat. As time progressed, energy problems started to occur and wind turbines were designed to obtain energy.
Wind turbines are machines that convert kinetic energy of air in motion into mechanical energy and then electrical energy. Wind turbines continue to develop in the most appropriate way according to the environment and living things
Propeller-free wind turbines generate electricity with turbulence. It allows the turbines to be shaken by using magnets regardless of the wind power. When the turbines start to swing, the alternator underneath turns the mechanical action into electricity. They designed the aerodynamic shape of the wind masts in such a way that the air currents lead to controlled turbulence along the mast. The masts swing like a pendulum in the wind, producing a frequency of mechanical oscillation. There are two equipolar magnets in the place where the upper part of these poles consisting of hollow pipes meet with the handle. In other words, while the two push each other, the magnet ring on the top makes it floating in the air. Thus, ring magnets transfer the vibrations of the pole to the dynamo and this alternating current generator converts the vibrations into electricity in the most efficient way.
Moreover, since they do not rub against each other, they do not cause overheating, energy loss and wearing out due to additional vibration. The alternating current generator under the pole converts the vibrations into electricity in the most efficient way. The trick is to create controlled turbulence, otherwise uncontrolled vibrations will only lead to the pole to collapse or the end to break and fall to the ground. To solve this problem, composite material consisting of fiberglass (glass fiber) and carbon fiber is used in pole manufacturing. The reason for using the fiber is that it is light and flexible, and it is quite resistant to turbulence with easy shaking in the wind. It also transfers its turbulent vibrations (the kinetic energy of the wind) to the charging dynamo without any loss. These turbines generate 30 percent less energy than conventional wind turbines. However, since they are without propellers, they take up less space. For this reason, the energy problem seen as a disadvantage turns into an advantage with the field.
Advantages of propeller-free wind turbines compared to propeller
- Migratory birds do not have any harm to migratory birds because they produce electricity by oscillating completely even if they are on the migration paths.
- Sound pollution is completely eliminated.
- 53 percent is less costly, while operating-maintenance costs are 51 percent cheaper.
- Since wind roses do not have moving parts, they do not need continuous lubrication.
- These wind roses do not have electrical motors.
- Fast or slow blowing of the wind does not affect these wind turbines since it does not depend on the speed of the wind.
- With its functional and easily assembled structure, it can be installed anywhere.
- They save space.
