Aeromine Technologies just closed a $9 million funding round, and it’s ready to scale up production of its bladeless rooftop wind turbines.

Energy research, investing, and strategy firm Veriten is the lead investor in Aeromine Technologies’ Series A funding round.

Aeromine, launched in 2022, makes compact 50 kW or larger “wind harvesting platforms” that it mounts on the edge of a building’s roof. The rooftop wind units, which have no external moving parts or blades, capture wind flowing up and over the building and convert it into onsite electricity. Its generator system is a rotor-stator system with a highly efficient 5 kW permanent magnet generator. (Specs are here.)

The noiseless technology leverages aerodynamics like airfoils on a race car to capture and amplify each building’s airflow to generate energy. Aeromine says its systems typically consist of 20-40 units installed on the edge of a building facing the predominant wind direction.

Each 1,000-pound unit can withstand winds of between 120 and 158 mph depending on specification.

Aeromine’s units can operate independently or be integrated with existing rooftop solar arrays. Onsite power generation eliminates grid supply disruptions.

Maynard Holt, founder & CEO of Veriten, said:

We believe that distributed power innovation will play a vital role in helping companies fulfill their need for reliable, reasonably priced electricity and desire for low-impact power. We’re excited to partner with Aeromine, as its ability to quickly and affordably help a wide variety of companies meet their energy needs with wind resources is unique among distributed energy solutions.

The bladeless wind turbines are designed to power apartment buildings, warehouses, manufacturing facilities, offices, hospitals, retail centers – basically any big box building with a flat, unobstructed roof.

The company says it has 400 qualified projects in its pipeline and expects to roll out commercially in Europe and North America in 2025.
