Pterofin’s oscillating wings capture energy from light winds, even below 5 MPH, to generate electricity or pump water. Our technology is useful in remote locations, especially rural and agricultural communities in emerging markets as demonstrated by multiple inquiries and order requests from a variety of nonprofit organizations in Mexico, Peru, Ecuador, and Kenya. Pterofin Inc. as well as the inventor, Wallace Kempkey, have been featured in tech press and local media outlets such as GeekWire and KOMOnews.com. "Birds and fish are extremely efficient at using energy to create motion in a surrounding fluid, so why not try to create energy by using that same motion within a moving fluid?" Pterofin products are controlled by a simple counterbalance system that synchronizes the wings’ position and speed with a mechanical leverage point on the body of the device. The outcome is a coordination of harmonizing the wings pitch angle to a natural frequency of a fluids specific velocity. This oscillating motion is low in RPM and high in torque, which allows it to be extremely efficient at pumping water. When a Pterofin encounters high winds, gust, or debris, a rotational control system allows the wing or wings to sweep back into the direction of the current, bringing Pterofin power to a halt and making it act at that point simply as a weather vane. This makes it much more aerodynamic and gives it a far more streamline profile than any turbine on the market. We'd like to think it knows how to hibernate or "go dormant" to avoid over-stress on the moving parts that leads to high wear and tear, and also creates far less noise pollution.
