Pteró (wing, winged, or feather) + fin (a surface used to produce lift in air or water) = Pterófin [ter-o-fin]
Welcome to Pterofin. Inspired by the natural movements of bird wings and fish fins, our innovative oscillating technology offers efficient, eco-friendly power generation at a fraction of the cost of traditional turbines.
Key Advantages of Pterofin Technology:
Key Advantages of Pterofin Technology:
- Wildlife-Friendly: Our gentle, oscillating motion significantly reduces the risk to birds and aquatic life, providing a safer environment for wildlife.
- Shallow-Flow Operation: Unlike conventional turbines that require deep waters or heavy winds, Pterofin's design excels in shallow currents, expanding the possibilities for renewable energy deployment.
- Enhanced Efficiency and Quiet Operation: By harnessing energy at higher reduced frequencies, our technology achieves higher lift coefficients, allowing for the extraction of the same amount of power at higher torques and lower RPMs. This results in lower relative velocities, which reduces noise and minimizes the impact on its surrounding environment.
Pterofin is currently working with the U.S. Department of Energy’s National Laboratory of the Rockies (NLR, formerly NREL) through TEAMER RFTS-15 technical support to quantify the performance of our Pterofin “Skimmer” technology. NLR’s team is actively advancing a 3D modeling campaign to translate our biomimetic concept into decision-grade metrics—most importantly a power curve and efficiency trends across realistic flow conditions. This work builds directly on our earlier lab testing by tightening the link between measured behavior and predicted output, helping us understand how design and control choices influence power production, loads, and operating envelope. As the study progresses toward a publishable results package, Pterofin will share a clear public summary of the headline findings. This milestone is a turning point: it’s the step that moves the Skimmer from “promising” to provable, and it strengthens the foundation for the next phase of prototype validation, pilot deployments, and commercial partnerships.
Recent tests at the Applied Research Laboratory (ARL) with Penn State University have validated many of these benefits for producing hydroelectricity, highlighting Pterofin's potential to operate efficiently in environments where traditional turbines cannot. The ARL scientists noted that our unique capability to extract energy at higher reduced frequencies allows Pterofin products to harness energy that would otherwise be inaccessible using conventional turbines. They emphasized that by operating in a highly unsteady flow field and achieving higher lift coefficients at high reduced frequencies, Pterofin can extract the same amount of power at higher torques and lower RPMs. This means lower relative velocities, which theoretically impacts both noise and fish strikes. The low RPM and oscillating movement are also ideal for pumping groundwater. Additionally, Pterofin's design enables operation in shallow locations, as the span of the wing and arch length can extract energy in much shallower conditions compared to turbines. Furthermore, the drive shaft and gearbox/generator run dry while positioned above the water, reducing noise and vibrations compared to turbines, whose components must be underwater.
Our mission is to deliver renewable energy solutions that thrive within nature. By integrating our technology into sustainable water systems, we aim to address global challenges like water scarcity and access to clean energy.
