AEROMINE
Aeromine Technologies, a subsidiary of the University of Houston, has created a new type of wind power generator. Its main advantage is the absence of rotating blades, which made it possible to make the installation compact, silent and environmentally friendly. Their efficiency exceeds the parameters of solar panels, so it would be more convenient to install only such systems on the same roof area of a typical house.
The operating principle of the Aeromine wind turbine is based on the creation of a zone of rarefied air between the guide wings and the central column. There are holes in them, where the wind drives the air, then passes through the pipes to a simple propeller, which already turns the generator. The system is stationary, all moving parts are hidden in the base and, if desired, the generator itself can be placed at any distance from the outside, which simplifies the installation of the unit.
The prototype power is reported to be 5 kW, an array of such windmills in the same area, which is occupied by 21 typical solar panels, generates up to 14.3 MWh per year, compared to just 9 MWh per year. for solar panels. Aeromine is constructed of the simplest and cheapest materials and is easy to dismantle, transport and repair. Obviously, such an installation will be cheap, but nothing is known about the price yet.
The Aeromine's cons are also in plain sight - a fixed system is not able to respond to a change in wind direction. It is quite voluminous, it is up to 5 m high along with the base, so although it takes up little space on the roof, it visually stands out. Also, it creates significant shade, so using such a windmill in combination with solar panels will not work. On the other hand, so far we're just talking about a working prototype, which may well "grow" into something more efficient and convenient.
