Aeromine’s patented wind system is vibration-free, quiet and easy to install, to be efficient and space-saving. The machine is tested in BASF
The first seemingly immobile small domestic wind turbine
(Rinnovabili.it) – It is offered as an alternative to the traditional and well-known Rooftop solar panels, but it promises to generate more energy with less space. Let’s talk about Small domestic wind turbines “without bladesManufactured by Texan Aeromine Technologies. The company recently introduced its patented wind capture technology, a solution validated by joint research with Sandia National Laboratories and Texas Tech University.
what is he talking about? In the appearance of a large fixed cylinder with side wings. Unlike conventional horizontal or vertical axis turbines, Aeromine’s small domestic wind turbines do not have blades. At least not in sight. The design uses racing car-like wings to generate aerodynamic forces that amplify the captured airflow. In other words, when wind hits the airfoil, it is literally “sucked up” passively towards the bottom of the unit. Here, hidden from view, the real turbine responsible for the production of electricity.
The company announced through a press release that the small domestic wind turbines are quiet, easy to install and resistant to any weather conditions. And that a number of companies, including BASF, are already testing it. “Systems can consist of 20-40 units installed on the edge of the building facing the prevailing wind direction, “ Read the press release. “Designed to work seamlessly with the building’s existing electrical system, the combination of Aeromine’s wind solution and rooftop photovoltaics can generate up to 100 percent of the site’s energy needs, reducing the need for energy storage.”
Little wind on the roof, when appropriate
The company doesn’t provide many details, such as unit capacity or costs. From documentpublished on the US Department of Energy website by scientists who validated the technology, we know that the device achieves a mechanical efficiency of about 1/3 of the Betz limit.
What is certain is that small local winds continue to flourish due to the great interest of consumers. The interest that is growing in a very sensitive moment like the present moment where electricity and gas bills, especially in Europe, have caused a real price crisis. Can such solutions reduce household energy costs? Much depends on technology, but positioning also plays a leading role.
In general, small and small wind turbines, while operating at lower wind speeds than large industrial wind turbines, still require a minimum starting speed. It is therefore of paramount importance to carefully consider the installation site (location, building height, etc.) before considering such a system. Help comes from two tools: global wind atlas From IRENA which provides accurate data on wind resources worldwide, easily, freely and accurately to km; and theAtlas Aeolianthe Italian anemia database from GSE providing data at 25 m, 50 m, 75 m and 100 m above ground level.
