![]() ![]() It does not require a nacelle or blades that are the most expensive parts of a conventional wind turbine, and the manufacturing costs are estimated to be about 53% of that of a conventional wind turbine. Owing to its simple shape and light weight of 15 kg, its material costs are reduced. Vortex Bladeless is designed to solve the problems of traditional wind turbines, such as operational costs, noise, and impacts on birds. Simple shape for cost efficiency, wildlife friendly, and low noise The wind generator is additionally equipped with a safety device to automatically stop working when wind speed exceeds 30 to 35 m/s, the maximum speed that the generator can handle. As it operates on low to medium wind speeds, it is energy efficient, generating the same amount of energy at a cost 45% lower than that of a conventional 3-blade wind turbine. When the wind speed is 6 m/s, or enough to raise dust and sway small branches, it can generate enough power. It starts generating power at a wind speed of 3 m/s, typical in urban areas. Vortex Bladeless vibrates using the power contained in its vortices that is generated when wind bypasses the structure and transforms mechanical energy into electricity. Generating energy using a vorticity phenomenon The generator is intended to be used in farmlands and residential areas. The company is currently prototyping for commercialization in the second half of 2020 for the price of approximately 200 Euros (around 25,000 Yen). The high-tech generator with a simple shape is protected by six families of registered patents. Vortex Bladeless, a pole-shaped bladeless wind turbine, was developed by a Spanish start-up Vortex Bladeless Ltd.
