Innovative Design and Low Inertia
This revolutionary HAWT (Horizontal Axis Wind Turbine) boasts an innovative design based on the Archimedes screw principle. Its unique structure allows it to absorb maximum energy from the wind's surface. The turbine's lightweight and transparent design minimizes visual impact and allows for optimal wind flow.
A key feature is its incredibly low inertia, enabling it to start generating electricity at wind speeds as low as 1 meter per second. This contrasts sharply with traditional windmills and allows for consistent energy generation, even in light winds.
The turbine’s self-orienting mechanism ensures optimal positioning relative to the wind direction, maximizing efficiency and minimizing wear.
Power Output and Efficiency
With a rated power of 1.5 kW, this small-scale turbine achieves remarkable efficiency. Even under average wind conditions (3.5 m/s), it generates approximately 1000 kWh annually in locations with wind conditions mirroring the average across Poland (70% of the country).
The turbine's performance scales exponentially with increasing wind speed, promising significantly higher yields in locations with stronger average winds. Its ability to generate power even from low wind speeds (starting at 2.5 m/s) ensures consistent energy production.
The turbine outputs low voltage (18-28V), which is boosted to 400V by an integrated booster, effectively making it a high-current turbine.
Mounting and Installation
Primarily designed for rooftop installation, this turbine offers versatile mounting options. It can be easily mounted on roofs, poles, or masts, offering flexibility to suit various locations and building types.
The turbine's lightweight design (under 50 kg) allows for straightforward two-person installation, even on rooftops. For taller installations (e.g., skyscrapers), ballasting or anchoring systems may be necessary.
Its compact size (2.5m sweep diameter) and height ensure compliance with most building regulations, negating the need for permits in many locations.
Durability, Maintenance, and Cost
Constructed from durable, UV-resistant PG material with reinforcing additives, the turbine is built to withstand harsh weather conditions, including strong winds (tested up to 140 km/h). Noise levels are kept below 40 decibels, ensuring minimal disruption.
While component replacement is possible, the high impact resistance of the PG material promises a long lifespan. A planned service campaign will address any potential long-term degradation issues.
The complete system, including turbine, scalable energy storage (0.5 kWh), converter, and mounting hardware, is priced at PLN 18,000 gross (approximately €4,000).
Conclusion
The Archimedes screw wind turbine presents a compelling alternative to conventional wind turbines. Its innovative design, high efficiency, and low-wind operation make it a practical solution for residential and potentially commercial applications.
Its durability, low noise, and ease of installation are significant advantages. While the price point is relatively high, the long-term energy savings and environmental benefits could justify the investment for many consumers.
The ongoing pilot program further demonstrates the commitment to continuous improvement and adaptation to diverse conditions, promising a future-proof and reliable energy solution.
