Introduction

To harness wind energy, it uses a fundamentally new methodology. Renewable energy is typically provided with electricity from such sources as wind, solar, geothermal, hydro, and various forms of biomass. Because of their steady replenishment and availability for repeated use, these sources have been coined renewable. Thanks to the depletion of conventional power generation approaches and the growing awareness of its detrimental environmental effects, the use of renewable energy has experienced a significant rise and creativity in recent times. Due to its global viability, wind energy technology has been one of the areas that have been under constant development and enhancement.

Types of wind turbine

Several types of turbines actually exist and their architectures tend to be one of two main categories: horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs). As the name implies, the direction of their rotor shafts separates each category. The former is the more traditional and common style that has been known to everyone, while the latter is quite uncommon due to its unusual use and exploitation Typically, the HAWT consists of two to three propeller-like blades fixed to a horizontal shaft and positioned on bearings above a support tower

Wind power accounts for a large percentage of global renewable energy, and with all the recent technological advances in the development of wind turbines, it is no wonder that it has become the rapidly growing source of clean energy. Engineers have developed new devices with sophisticated technology that is more efficient and safer for birds. While the air is still there, some wind turbines can generate energy.

The world’s first typhoon turbine: rely on the vast amounts of energy in the storms. Egg beater-like contraption is a Magnus wind generator with a vertical axis that is robust enough to endure a typhoon’s high winds.

A hybrid wind-hydro turbine: For the world’s first hybrid wind power plant, Max Bögl Wind AG and GE Renewable Energy are combining conventional bladed turbines with hydropower systems. It features four 13.6 megawatt capacity wind turbines.

Helium-filled floating wind turbines: New advances brought turbines up in the air, where wind moves faster than ever before. Float 1,000 meters in the atmosphere, five to eight times as strong as the winds to capture wind currents at ground level. Altaeros Energies claims that its floating wind turbines in Alaska will reduce the cost of its generated electricity to $0.18 per kilowatt-hour which s half of the current off-grid electricity price.

The Vortex Bladeless wind turbine: Bird welfare is a major issue in the wind turbine environment. To mitigate the risk to birds, the Vortex Bladeless wind-energy turbine is developed by engineers which are formed as a tall, thin straw rather than huge rotating blades. The system harvests power from spinning vortices of moving air, and since the bladeless wind turbines are tall and thin, most of them can be installed in the area covered by a single blade turbine.

Saphonian Bladeless Wind Turbine: Developed by the Tunisian Saphonian Energy company, it is a drastic change compared to other models. This innovative design premises to be more efficient compared to other designs. Current wind turbines are 30-35% and the company claims that its test shows that its design more efficient than the traditional ones.

Drawbacks of wind turbine

  • The main disadvantage is that the wind turbine is more expensive.
  • The starting wind speed of conventional windmills is high and similarly conventional windmills are unable to rotate at high speeds and as well as conventional windmills are unable to harness energy at low wind speeds of less than 1.5 m/s.

Bladeless concept

The aspect that separates this type of wind generator from others is that it is fully supported and rotates without the risk of killing livestock. This is oriented vertically with the moving mast and generator in the center. It seems that the most successful position of the simple generator inside the mast would be. The magnet used in the inside of the coil is a cylindrical shape magnet that moves and generates electricity.

Advantages

Vortex’s dramatically low cost is one of the main advantages, including capital costs, operating and maintenance, performance, land leases, insurance, and other administrative costs.

Generation expense from various sources. This places the technology for such projects at a very low range of capital intensity. It also makes it highly competitive not only against green or renewable energy groups but even against traditional technology. These cost reductions are the result of reduced production costs: the tower and generator equipment are essentially one and the same. The architecture eliminates mechanical aspects that can suffer from friction wear and tear, resulting in an estimated 53% decrease in maintenance costs compared to traditional wind, avoiding oil change or changing most of the mechanical parts over the 20 years of the life cycle of the multi-blade wind turbine.

Disadvantages

The electrical generation is influenced by changes in the environment. The requirement for control systems monitoring the oscillation to satisfy the mast’s normal frequency and vibration stability at higher speed winds. Depending on the appropriate performance, the mast height can be increased.

Future scope

The bladeless turbine wind generator is the best choice for generating electricity using wind power because of its multiple benefits. It will help to increase the percentage of renewable energy for generating electricity and provide customers with a reliable and economically efficient capacity. It can be mounted on a roof and is very functional and effective. A tenant would be able to generate free clean energy and thus experience a reduction in their utility costs and also contribute to the growing popularity of the “Green Energy” awareness.  The drawback with a bladeless wind turbine is that the initial cost is high, but once applied, the operating cost is much lower as it reduces the initial cost. Another concern is understanding of this definition. This concept, which has much less awareness in the world, is therefore very slow to research and develop this concept. This concept must, therefore, be spread because only renewable energy can survive in the future and wind energy is an efficient option in the future.
