At Pterofin, we believe in the power of simplicity. Our technology is based on a straightforward design, but it is optimized for performance and reliability through extensive testing and innovation. By focusing on the efficient harnessing of wind and water energy, we’ve developed a technology that is versatile, scalable, and sustainable.
To validate and refine our technology, Pterofin partnered with the Applied Research Laboratory (ARL) at Penn State University. Thanks to TEAMER, a partnership funded by the Department of Energy, we were able to conduct a series of tests to better understand the hydrodynamic performance of our oscillating fins. Our goal in these tests was not only to examine power output but also to gather critical data on key design variables that impact performance:
Reduced frequency
Flapping/pitching angle ratio
Reynolds number
The data from these tests has been invaluable in further developing the technology and was submitted to the Marine and Hydrokinetic Data Repository, allowing the broader scientific community to review and benefit from our findings. Key Features of Pterofin Technology What sets Pterofin apart from traditional turbines is its unique combination of simplicity and innovation. Our products are designed to be efficient in both low and high current conditions, with features that maximize energy extraction while reducing environmental impact.
Natural Oscillation and Energy Transfer: At the core of our technology is a simple yet ingenious counterbalance system. This system synchronizes the position and speed of the wing/fin with a mechanical leverage point on the device, allowing the wings to pitch at a natural frequency that matches the velocity of the surrounding fluid. This results in a highly efficient energy transfer process.
Adaptable to Harsh Conditions: Our rotational control system enables the wings to automatically sweep back when faced with high winds, gusts, or debris, akin to a weathervane. This ensures the wings maintain an optimal aerodynamic profile even in extreme conditions, surpassing the performance of traditional turbines, particularly in stormy weather.
"Hibernate" Feature for Durability: Pterofin also features a unique "hibernation" mode, allowing the system to go dormant during periods of low energy demand or high environmental stress. This reduces the strain on moving parts, minimizing wear and tear while maintaining virtually silent operation. It ensures longevity and reliability, making Pterofin a more durable alternative to traditional renewable energy systems.
Key Advantages of Pterofin
Efficiency in Low and High Currents: Unlike traditional turbines, Pterofin can operate effectively in both slow-moving and high-speed currents, making it suitable for a wide range of environments.
Cost-Effective and Easy to Maintain: Pterofin’s design features fewer moving parts, reducing the complexity and cost of maintenance. The moving components are located at the base of the oscillating wings, making installation and upkeep more straightforward and affordable.
Environmentally Friendly: Our technology is designed to reduce environmental impact. Unlike turbines, which can harm wildlife, particularly marine life and birds, Pterofin’s gentle oscillating motion minimizes these risks.
Quiet Operation: Pterofin operates with little to no noise, making it ideal for installation in both rural and urban environments without disturbing wildlife or communities.
Aesthetically Pleasing: With its sleek, minimalistic design, Pterofin is visually unobtrusive, blending seamlessly into natural landscapes, unlike the large and imposing wind turbines.
Material Versatility: Our technology can be made from a variety of materials, allowing for cost-effective mass production and easy deployment across the globe.
A Scalable and Adaptable Solution Pterofin technology is scalable to meet diverse energy needs, from small, portable systems ideal for remote or off-grid locations, to large, industrial-scale installations capable of powering entire communities. Whether used in shallow waters, coastal areas, or for onshore wind applications, Pterofin’s modular design can be tailored to different environments, making it a flexible solution for a variety of renewable energy needs. Global Impact: A Solution for Emerging Markets Our technology has already attracted significant interest from nonprofit organizations working in underserved regions, including Mexico, Peru, Ecuador, and Kenya. These areas face significant energy and water challenges, and Pterofin's ability to provide sustainable, low-cost energy solutions is positioned to make a meaningful difference. Pterofin has also been featured in top tech outlets, such as GeekWire, KOMOnews.com, and TEDx, highlighting our recognition in the renewable energy space. Our Vision: Empowering Communities Worldwide In the near term, we aim to deploy Pterofin prototypes—such as the Skimmer and Dragonfly—to gather data and refine the technology before moving into large-scale manufacturing. Our long-term vision is to share our technology with rural and underprivileged communities, providing them with reliable, renewable energy for both water and power needs. Through licensing intellectual property agreements with manufacturers interested in advancing environmental sustainability and reaching new market segments, Pterofin is poised to revolutionize the renewable energy sector, bringing affordable solutions to both developing and developed markets.
