Most wind turbines today are horizontal axis turbines (HAWTs), which require heavy, high-mounted components and complex mechanisms to face the wind. These systems are expensive to install and maintain, create noise pollution, and generate mechanical stress that shortens the lifespan of their blades—many of which are hard to recycle.
Vertical axis wind turbines (VAWTs) solve some of these issues by placing components near the ground and eliminating the need to rotate toward the wind. However, they struggle with efficiency because their blades must push against the wind during part of each rotation, creating drag and limiting scalability.
The Invention
This invention is an advanced VAWT design that uses adjustable blades to improve energy capture and control. Each blade has a wing that can automatically rotate to the ideal angle depending on wind direction and its position in the rotation cycle. A central control system—guided by sensors—adjusts each wing in real-time to maximize or reduce wind capture as needed.
The Innovative Step
Unlike traditional VAWTs, this turbine can actively control blade angles to either boost efficiency, slow down, or completely stop—without using mechanical brakes. This is achieved through a system of pivoting wing axles, a yaw control shaft, and a feedback loop that senses wind conditions and turbine performance.
Tangible Benefits
- Higher efficiency and energy output
- Lower maintenance and material costs
- Longer blade lifespan
- Safer operation with fewer moving parts prone to failure
- Easy installation and servicing due to ground-level components
