A US startup has presented a new mini wind turbine that can in principle be installed anywhere on buildings. There are no rotor blades, which makes it possible to produce electricity almost silently. The system should be cheaper than photovoltaics and still generate more energy.

Wind turbine presented to everyone

Aeromine Technologies has presented a new mini wind turbine that can be used almost universally. With dimensions of around three by three meters, it is significantly smaller than existing models and works entirely without rotor blades. The otherwise usual background noise can therefore be dispensed with, which suits the use in residential areas.

The system makes use of the effects of aerodynamics. Oncoming wind is centered and amplified, like the lift mechanics of airplane wings. A turbine installed inside the system is driven by the air flow. According to Aeromine, the system only needs ten percent of the roof area that is required for photovoltaics. At the same cost, the mini wind turbine produce about 50 percent more energy (Source: Aeromines).

The engineers see one of the greatest advantages in the fact that the wind turbine can also produce electricity at night. One continuous energy production is possible in some places. Ideally, photovoltaics will be combined with wind energy to further reduce electricity costs.

New wind turbine: market maturity planned for 2023

The plant is currently still in the test phase, which is being carried out together with BASF in the US state of Michigan. After successful tests, the mini wind turbine will initially be offered to commercial customers, who can install it in office buildings or factories, for example. With a sale to private individuals will at the end of 2023 at the earliest expected.
