In recent years, as people's awareness of environmental protection, clean energy is widely welcomed, wind power is one of them. Currently, most wind turbines in operation are almost 20 stories tall and carry three long blades about 200 feet long. When these blades rotate with the wind they generate electricity, but they also strangle those flying near Fan birds. Statistics from the United States show that nearly 600,000 birds die every year in the United States under the huge turbine blades of these wind turbines. However, this issue seems to be going to be cracked now. Vortex Bladeless build blades without fans Vortex Bladeless, a technology company from Spain, built a fanless blade. According to the design team, this seemingly mast-like fan has a "totally different principle of power generation" and instead of relying on rotating blades or any lossy activity, it takes advantage of a design that has plagued architects and engineers for years The effect of the wind, the "vortex shedding effect," is that when the wind hits the building and flows over its surface, the air flow changes and a circulating vortex develops at its own tail end, which allows the fan to Like a huge straw swinging in the wind, thus generating electricity. The researchers explained that in fact this principle is called "Krmn vortex street" (Hungarian American aerodynamicist Theodore å€ å€ thrown neodymium but never ç º 凵 凵? éž«? 妹 sister?

Instead of avoiding this aerodynamic instability, Vortex Bladeless engineers do their job by utilizing the vortex shedding effect that exploits the swing caused by it to gain energy. This mast-shaped fan includes a fixed mast, a generator, and a semi-rigid glass fiber cylinder to ensure that it swings back and forth in the wind. There are no moving parts connected to each other between the generator and the mast. At the same time, the generator is a system of magnetic couplings, which means it has no gears to lubricate, and the entire system requires less maintenance. According to David Suriol Puigvert, co-founder of Vortex Bladeless, David Suriol Puigvert introduced a vane-less mast-shaped wind turbine system at significantly lower costs than conventional wind turbines. The company's data shows that this bladeless fan costs about 53% less than a conventional fan while reducing maintenance costs by as much as 80%. In addition, vaneless fans reduce carbon emissions and generation costs by nearly 40% compared to conventional vane fans. In the meantime, due to the absence of blades, the fan operates quietly, minimizing the environmental impact on the site of the fan and no longer threatening the birds' survival. However, although the technology is conceptually well established, it is still undergoing field testing and tuning. It is understood that, Vortex Bladeless initially focused on large-scale power generation equipment, the main development of 1 MW and above installed capacity of large fans, hoping for large-scale power generation. According to Pricewater, which is still the company's long-term goal, it is estimated that a 1 MW generator will be available to the market after three years. Taking into account the fan blades, occupy less space, Vortex Bladeless companies began to focus on the development of small fans. Currently, the company has set the short-term goal of creating a wind turbine with a height of about 13 meters and an installed capacity of only 4 kilowatts. Vortex Bladeless wants to combine this generator with a solar-powered system and targets mainly home users who do not have access to the grid or want to leave the grid. In addition, the company is also developing a mini vaneless fan with a height of only about 3 meters, with a capacity of 100 watts. Vortex Bladeless believes this product, called the Vortex Atlantis, will be used in areas that are not connected to the grid and will be a good choice for many areas that lack power and are economically underdeveloped. Like a 4 kW fan, this mini blower will be used in combination with a solar power system. It is estimated that in about one year, these devices will be on the market. In addition, Vortex Bladeless expects to introduce a 1 MW generator to the market in about three years. Pfert said that the company has raised over 1 million euros of European private and public funds, is expected to launch this year, the commercial prototype. According to Forbes News, Vortex Bladeless's R & D funding so far has come mainly from the Repsol Foundation grant, the Spanish government loan, and venture capital and angel investments in Spain. Currently, the company has relocated its headquarters to Boston, U.S.A., and has partnered with Harvard University, SunEdison and IDEO.
