Pterofin, Inc. Information

Pterofin is a clean technology company developing innovative energy generation devices based on biomimicry. Our current focus is on a customer who at the village level faces high costs and inefficiencies in pumping water from deep wells using existing electric pumps or outdated wind turbines. 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. 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. Our near-term goal is to get Pterofin prototypes into the hands of sustainable energy enthusiasts as an avenue to collect data before mass manufacturing the Dragonfly. Our long term goal is to share the Dragonfly with underprivileged communities in need of power and water as well as rural and agricultural communities without the finances or wind required for the average turbine. Unlike a turbine, Pterofin technology is: efficient in low currents, inexpensive to manufacture, reliable in heavy currents, has a low cost of maintenance, quiet operation, is environmentally friendly, aesthetically pleasing, and can be made out of a wide variety of materials allowing it to be mass produced and easily adopted around the world.
