[ter-o-fin] Pteró (n) - wing, winged, or feather. + fin (n) - a surface used to produce lift in air or water.
Pterofin is a renewable energy company developing innovative products based on the biomimicry of a bird's wing or fish's fin. Our unique oscillating wings are mechanically driven to convert energy, even below 5 mph wind or 1 mph water current, to pump water or generate electricity.
Skimmer - surface water
Manta - underwater
Dragonfly - double wing
Terrafin - single wing
Our primary 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the village level faces high costs and inefficiencies in pumping water from deep wells using existing electric pumps or outdated wind turbines.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 technology can be extremely 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 fluid's 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 or rudder. 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.
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 Skimmer and Dragonfly. Our long term goal is to share this technology with underprivileged communities in need of power and water as well as rural and agricultural communities dealing with finances or environmental constraints.
Wind turbines typically require a 70-ft guyed tower as well as a substantial financial investment. Pterofin’s key moving components are mounted at the base of its unique, oscillating wings so they are easier to install and maintain and the materials can be sourced easily. In heavy winds the Dragonfly is silent compared to the 55db of a typical small wind turbine and doesn't pose a threat to birds, bats, or our hearing.
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.
Through licensing IP agreements with manufacturers who are interested in helping preserve our environment, improve their product line, and expand into new segments that were previously unattainable, Pterofin technology is going to be the next generation of renewable energy for first and third world countries.

7/24/2017 Pterofin, Inc is ready to start collecting some real data on it's latest wind energy prototype once we find somewhere to install it in the great outdoors.
3/28/2017 We tested our wind energy prototype today at the Kirsten Wind Tunnel and were very pleased with the results. In order to refine our technology we've simplified the design to eliminate components and complexities in collecting concrete data on its efficiency. Soon we will be installing a new gearbox and flywheel to help it reach its full potential in power output. We are also working to display the kw/hours in real-time here on pterofin.com,
8/25/2016 This is one of Pterofin's single wing prototypes, made of PVC and Bamboo canvased with plastic wrap. The power being produced lights up a LED from a shake flashlight, with its magnet attached to a cable, which is attached to a lever arm protruding from the drive shaft that holds the wing.
7/5/2016 One of the most important factors in creating successful forms of alternative energy is efficiency, the ability to generate useful levels of electricity affordably. The latest prototype, the Terrafin, was built using common parts from any hardware store or junkyard and cost less than $50 to build and can be maintained for pennies.
8/22/2015 This video is a short introduction to the evolution of Pterofin technology.
8/16/2015 I'm currently speaking to a few interested parties who are fascinated with the Manta's potential energy output using tidal and oceanic currents. Check out our quick animation of the Mantain action.
7/30/2015 Today I was a presenter at the "Thingamajig" showcase event at the West Seattle Elementary School! All of the kids were really excited to learn about my alternative wind energy technology and to hear my story about filing a patent and starting Pterofin, Inc. The kids had so many questions about my invention ranging from, "How long did it take you to build it?" to "Can I ride it?" The high level of curiosity and ingenuity really left me inspired. The highlight of my day was after my presentation to the last group of kids, one of the kids approached me, held out a fist bump and said "You're a hero." I will definitely continue my relationship with this project for as long as humanly possible.
6/22/2015 Another milestone for the Pterofin Dragonfly! We took 'Peoples Choice Award' at the CleanTech Alliance Showcase 2015 for Best Emerging Company! You can download the poster by clicking here.

10/3/2014 I completed the first of many high wind speed tests today to demonstrate the pitching back portion of Pterofin technology. The video posted shows a Pterofin moving 25mph in it's dormant state, proving it's versatility and reliability.
6/25/2014 Today I finished building a half scale Dragonfly modelthat will be purchased and installed at a few different locations here in Seattle. One of the locations is a public park in Fremont, looking to install three of my wind energy products to power lights along a path in the park. Check out the video I posted on youtube and check back for more videos of the high and low wind speed tests we'll perform over the next few weeks.
5/29/2014 I was given a second opportunity to present Pterofin at a Fulbright “From Lab to Market” Seminar today and had an amazing time! The students seemed to really enjoy our presentations and discussions about our companies pushing through the world of "clean-tech" and strategic business planning.
2/10/2014 My latest prototype was retrofitted with a second wing to increase its efficiency, to help it track the wind, and to showcase the effectiveness of the biomimicry in its design. This modification converted the model from a Terrafin to a Dragonfly design, which I'm hoping to replicate all over the world to pump clean drinking water for impoverished populations.
2/10/2014 I asked for some wind and got a wind storm! Unfortunately, I'm starting to realize that this might not be the best place to test a wind generator, because of all the surrounding trees and a massive house in the way. I added a few weights behind the pump to simulate the weight of the water, which allows us to start collecting data on when the wing will pitch back. After a few other adjustments to the counterweights and bungee cord, I should be able to add the water and start measuring it's power output.
2/8/2014 I just finished installingthe latest prototypeand now I'm waiting for some wind to come through. The upcoming weather is supposed to be pretty bad, so I'll see what kind of video I can shoot and what kind of data I can collect over the next couple days. Exciting times!!!
12/19/2013Jacob’s Well and Panes y Peces bring food security and true sustainability to the poor and impoverished communities throughout the Americas at no cost to them. One of the main challenges they face is an affordable energy source. Pterofin’s wind and hydroelectric generators are ideal solutions to pump and heat water during some of the colder winter days. Warm water ensures a thriving population of Tilapia fish and healthy plants. I'm looking forward to sharing results of our wind prototype and seeing the benefits for the people in these rural communities. If you would like to get involved or donate to this effort, please contact Jacob’s Well or Pterofin.
12/9/2013 Our latest prototype is up and running again, except now it has a water pump and a permanent magnet alternator! The system is quite unique to say the least, having three separate containers and using air pressure instead of head pressure to generate hydroelectricity. This closed loop system produces a water jet that turns a pelton wheel, which will charge a car battery and eventually power a few on board LEDs. We also raised the body of the prototype, so now the counterweights swing over the base and the two rear fins are much larger to help track the wind.
10/27/13 I installed the new prototype today at a secret testing location before moving it to Ballard High. This will give me a great opportunity to work out the bugs and make sure everything is safe for the students to perform tests on it's efficiency.
9/13/2013 Today we started building our first pilot prototype in the metal shop at Ballard High School! They have the most amazing location on campus to install and test the prototype, and we're working with two teachers and several students on collecting the data we'll need to prove this amazing new technology exist!
9/4/2013 We're excited to announce our first pilot installation happening in just a few weeks! This prototype will start with pumping water in a fountain to demonstrate how our products can be made using simple materials found in developing countries. After we measure the head pressure and gallons per minute, we'll switch to pumping water and generating hydroelectricity using a small water turbine and car battery for charging mobile devices.
8/17/2013 Tested the latest all bamboo wind prototype at the park today and it worked GREAT! There was no pump or generator installed on it yet, so without a load to slow it down it was really flying back and forth! If the wind picked up a little more it would have pitched all the way back and stopped.
8/1/2013 Pterofin is now working with K&L Gates on our intellectual property and communications between us and the USPTO. Our last Office Action Response was filed on July 8th, 2013 and our patent is still pending through the Green Energy Fast Track that Obama started in Dec. 2009. Everything looks very promising so far and the patent should be issued to Pterofin later this year or early 2014!

Eight years of hard work and dedication has gone into what will soon be considered the second generation of natural renewable energy and a potential world energy crisis will subsequently emerge as yet another feat of human ingenuity.
"The concept came to me almost 10 years ago, but I became truly inspired to see it through and start a business after joining the Napa Noon Rotary Club in 2006. After listening to a fellow Rotarian talk about his experience funding, traveling, building and installing a well with a wind turbine, I realized that depending on who and where a person is, a glass of clean drinking water can be far more significant than any glass of wine. Six years of R&D finally paid off as I came to design the cheapest form of renewable energy to help save lives on a global scale. I filed the provisional patent in 2010 and started Pterofin LLC to house the IP of the invention. The non-provisional patent was filed one year later after winning and placing in a number of collegiate competitions all around Seattle. The patent is currently pending with the USPTO on the Green Energy Fast Track, which means it should be issued to us some time in 2015. Please check out our videos of a few prototypeswe've built over the years, and the many published articles on the patent and the Pterofin project. Hope you enjoy our website and Cheers!" - Wallace Kempkey
