Sauer Energy WindCutter Analysis Completed

OXNARD, CA--(Marketwired - November 30, 2016) - Sauer Energy Inc.® (SEI) (OTCQB: SENY), developer of the patented WindCharger® vertical axis wind turbine (VAWT) and manufacturer of the patented WindRider® vertical axis wind turbine, is very excited to announce that the WindCutter has successfully completed thorough mechanical engineering review. The WindCutter has been with ATA Engineering, Inc., for the better part of a year now, undergoing operating strain gauge testing and computer model engineering finite element analysis (FEA) simulations to make sure every part of the turbine is as safe as possible.

About ATA Engineering, Inc.

ATA Engineering, Inc (ATA) is an engineering consulting firm that provides innovative solutions through test and analysis-driven design by focusing on the engineering needs of manufacturers in addressing their reliability, cost, quality, and time-to-market challenges for mechanical and aerospace systems.

ATA staff are experts in the design, testing, and analysis of complex mechanical structures. They use testing and analysis coupled with computer-aided engineering and mechanical engineering software to solve challenging problems in a wide variety of industries. Their engineering services include structural design, structural dynamic response analysis, stress analysis, thermal design and analysis, modal test, operational and qualification testing, model correlation, durability analysis, computational fluid dynamics, and vibro-acoustics.

With regard to the rigorous testing and analysis that the WindCutter has been undergoing at ATA, the preliminary results are in and the WindCutter has yielded spectacular results and will likely be the first vertical axis wind turbine in its class to be certified in the United States.

ATA's Rory Davis, PhD, PE, Lead Engineer of Analysis-Driven Design and Senior Technical Advisor, stated, "The fatigue resistance of the WindCutter machine was found to be quite good, based on the results of our accurate modeling approaches and strain gage test data. No design modifications were necessary to meet IEC requirements. Models were first correlated with actual operating test data to ensure that we knew the aerodynamic blade forces well for confident design analysis. Good quality manufacturing and QA welding processes in place at SEI will ensure this high fatigue life margin is maintained."

Sauer Energy's CEO, Dieter Sauer, commented, "It is no secret that this process took a considerable amount of time and expense. There was no option but to make sure we got this right! We can offer the WindCutter with the confidence of knowing that it is safe. Now, we can realign our focus on sales and revenue reporting activities."

The WindCutter successfully met all the criteria per the International Electrotechnical Committee (IEC) Standard IEC 61400-2 for "Small Wind Turbines." It was verified by high-accuracy engineering analysis to Small Wind Turbine Class 3, which includes sustained 50-year extreme winds of up to 117 mph, as well as worst case gusts stipulated by IEC.

The Small Wind Certification Council is actually the agency that certifies turbines. By concluding this meticulous mechanical engineering review, including correlation testing, the WindCutter has fulfilled a good portion of their criteria and is well on its way.

All aspects of the WindCutter were analyzed, including the main shaft, the blades, the strut assembly that connects the blades to the main shaft and the 10m fixed pole, as well as our proprietary braking system.

This is a clear demonstration of Sauer Energy's commitment to innovation and adherence to the highest measure of quality. It has always been a primary goal to provide a safe and strong turbine.

In-house Prototype Fabrication

Sauer Energy is unique because the "think tank" and "make it a reality" departments are all under one roof. Done elsewhere, fabrication is very expensive and it takes time, but to our team it comes naturally. And naturally, it is extremely cost-effective and time-saving to do it ourselves.

All aspects and every key element was engineered and integrated from the ground up. The IEC standards were strictly followed, so as to ensure that certification would be imminent.

The WindCutter design was refined over and over, our team carefully calculating the next steps as they strived for excellence. From one to the next, the iterations improved the design and performance. Hundreds of hours were spent in prototyping and real-life testing.

Engineering and design supported the layout and production design completed. Technical viability and operating performance from prototyping to manufacturing has been completed, and suppliers and materials are in place.

There are already purchase orders of approximately $2.4M in the pipeline. We have the ability to manufacture to meet those demands.

About Sauer Energy Inc.

Sauer Energy Inc. is a technology developer and manufacturer focused on the emerging renewable energy market. SEI's first offering, the WindCutter, is based on the Darrieus principal and has five airfoil blades that use the principle of lift to rotate the shaft and is pole mounted.

SEI also plans to offer the patented helixical WindRider model, a vertical axis wind turbine that employs the HelixWind® technology that it purchased in 2012. The higher performance design modifications are expected to deliver superior results. The WindRider is also pole-mounted, and can be used for applications that don't require roof mounting. SEI invented and also plans to offer the WindCharger® brand turbine for a better roof-mounted solution for residential and other small building usage.

SEI's technology is remarkable as it requires so few parts. This means a lower manufacturing cost, more efficient operation, lower maintenance (fewer parts = less chance of malfunction), and greater power generation. This will provide SEI with a new direction for wind capture, making it easier to scale from residential, to powering a small community -- all the way up to large industrial facilities. The market opportunity for this new, self-contained, innovative technology is unlimited and growing rapidly.

With several patents in place and many more pending, SEI looks forward to manufacturing and commercialization. It is also aggressively moving toward a financial return on its investments. To learn more about Sauer Energy, please visit: www.SauerEnergy.com
