92-Year-Old Retiree Develops Wind Turbine That Promises to Revolutionize the Renewable Energy Market. The Wind Turbine Features a Different Design and Promises to Be Up to 3x More Efficient.
The transition to more sustainable energy sources is crucial to ensure an environmentally safe future. In this context, wind energy, generated from the force of the winds, emerges as a key element in the replacement of fossil fuels. Engineers and specialists in the field of renewable energy are constantly seeking to improve the efficiency of wind generators. This effort has resulted in a variety of equipment, ranging in size from imposing wind turbines to compact versions designed for residential use and mobility systems.
New Wind Turbine Developed by a Retiree Is Up to 3x More Efficient Than Traditional Models
Among those contributing to the innovation landscape in renewable energy is Horst Bendix, a 92-year-old retiree residing in Leipzig, Germany. Horst conceived a wind turbine model that claims to be up to three times more efficient than the generators currently in use.
The retired engineer served as the head of research and development at Kirow, a heavy machinery manufacturer based in Leipzig, until his retirement in 1995. With extensive experience in designing lignite excavator cranes, Horst developed a wind turbine that delivers superior performance and requires less space for electricity generation.

A study reveals the expansion of renewable energy procurement in Brazil and shows how companies are taking advantage of opportunities to reduce expenses, ensure energy efficiency, and strengthen strategic environmental commitments.
This innovation has the potential to be a significant advancement in the renewable energy segment, overcoming the need for large areas for wind farms. Horst’s design can harness winds at altitudes exceeding 200 meters. He points out that this method provides superior energy performance, as the winds at this altitude are stronger and more consistent, leading to more productive wind harvesting. The design of the new renewable energy generator is different from conventional ones.
In the developed prototype, the traditional single tower of the turbines is replaced by a three-legged structure made up of a vertical column and two supporting columns. Additionally, the configuration no longer includes a single generator on top of the nacelle; instead, multiple generators operate at the bottom of the turbine.
Learn How the New Wind Turbine Works
Called the Bendix Wind Turbine, the innovative proposal bears the surname of its creator. The project’s differentiator lies in the modification of the classic structure. While common generators have a tower supporting a concave rotating structure containing the rotor hub and rotor blades, the retiree’s version for generating renewable energy features a distinct approach. Here, the energy generator is installed in a separate frame, and the system is secured to a three-legged base.
However, these systems face a significant challenge related to bending forces. The wind exerts considerable force on the rotor, reaching several tons. As a result, the tower bends, requiring substantial resistance to withstand this bending, which in turn necessitates a large moment of resistance in the ground.
As the tower increases in height, bending forces intensify, leading to greater instability and risks of damage to the structure. Horst’s idea is to replace the conventional tower with a tripod made up of a vertical column and two supporting towers.
New Wind Turbine Can Generate Up to 30 GWh Per Year
The innovation developed by Horst Bendix has the potential to triple the energy output of a single wind turbine. Experts, such as Frank Zeulner, highlight the prospect of great success for the new turbine, anticipating a harvest capacity of more than 20 to 30 GWh per year, compared to approximately ten gigawatt-hours of a conventional turbine.
Stability is significantly enhanced due to the reduced load on the top of the tower, eliminating the high bending forces associated with traditional turbines, allowing easy access to higher areas with stronger winds, and consequently, substantially superior performance.
