Hercules Natural Wind Turbine is the flagship of the ENESSERE constellation, a marvel of wind engineering that combines high-quality materials with impeccable design.

Its sails are covered with 40,000 strips of paulownia wood inserted one by one onto the carbon fibre skeleton by our master craftsmen. This meticulous attention to detail not only creates a lightweight structure, but it also gives it an unparalleled elegance.

Furthermore, the Hercules Wind Turbine tower is made of stainless steel, ensuring resistance and durability over time even in the most hostile environments.

With Hercules Wind Turbine, aesthetics meets power, resulting in a work of art of wind energy.

Paulownia wood comes from the Paulownia Tomentosa tree, known for its ecological characteristics: this tree grows in record time and produces 4 times more oxygen than other trees.
The Paulownia Tormentosa has been used for centuries in Japanese cabinetmaking to make cabinets where the most precious objects were kept, such as silk kimonos and often musical instruments. Even today, the load-bearing beams of the roofs of houses in Japan are made of Paulownia, thanks to its characteristics of lightness and ductility.


The use of stainless steel for the Hercules Wind turbine tower is a choice that goes beyond corrosion resistance. This high-quality material is virtually immune to rust, ensuring exceptional durability, especially in coastal environments where the salinity of the air could represent a challenge to other metal alloys. In these locations, where wind production is often optimal, stainless steel becomes the ideal partner, ensuring a reliable and long-lasting operation of the ENESSERE wind turbines.
