• 16 questions answered about the status of SheerWind projects

Q1: What is the status of the SheerWind projects?
SheerWind has seven beta units at different stages of installation and commissioning. The only one that was is at pre-commissioning evaluation (that is, at Stage 3) is in Fort Custer, Michigan. The other six units are at Stage 1 of installation, meaning that the funnel has been constructed and has been subject to inspection and speed tests.

Q2: You mentioned stages of installation and commissioning, how many stages are there?
We have four stages before we fully commission a unit. Stage 1 is site analysis, design, fabrication, and construction of the funnel. Stage 2 includes inspection and verification of the funnel to determine that wind speeds are accelerated as planned. At Stage 2, the wind speed data is collected, analyzed, and compared with predicted speed magnification. Stage 3 (pre-commissioning) is the installation of three wind turbines and related converters and control system; system integration and inspection of the electronics are done at this stage, as well as, collecting wind speed and power data. In Stage 4, we commission the system and focus on continuous operation, power generation, and energy production over a time period.

Q3: How is the Army National Guard installation at Fort Custer doing?
This unit was pre-commissioned (Stage 3) in early June of 2017. The pre-commissioning of this unit was disappointingly delayed due to multiple issues with off-the-shelf equipment and electronics provided by our vendors. More than 85 percent of our challenges and delays have had nothing to do with the INVELOX funnel technology. We have gone through stages 1 and 2, and we have been at Stage 3 for more than 18 months.

Q4: What has happened during that 18 months?
After the INVELOX funnel was installed (Stage 1), in Stage 2, we measured wind speeds inside the Venturi section of the INVELOX system and compared it with free-stream wind speeds (undisturbed outside wind speeds). For example, the wind speeds in the Venturi unit were from 20 to 90 miles per hour while free wind speeds were in the range of 4 to 26 miles per hour. The wind speeds inside the Venturi were more than ample to turn multiple turbines and generate the expected power. It should be noted that traditional turbines require 8 mph outside wind to begin turning, 26 miles per hour to begin producing nameplate power, and at about 56 miles per hour, the turbine is shut down. 

Satisfied with the wind speeds inside Venturi section of the funnel, we proceeded to Stage 3, in which we installed three turbines and related electronic and safety equipment. The turbines turned as expected but soon began shutting down continually due to a vibration fault tripped the safety chain of one of the turbines. SheerWind and vendors spent more than a year trying to determine the source of the vibration that shut down the turbines each time they turned faster than 300 RPMs, (the system starts generating power 350 RPMs). After a year of a frustrating search for a solution to what appeared to be a mechanical vibration problem, it was finally discovered that an improper cable was installed and it was causing the false vibration alarm. The cable was replaced, and the turbines ran as high as 1,400 RPMs without shutting down. That was good news, that arrived after a full year of exasperating trouble shooting. Once the turbines were turning with no vibration fault, we were prepared for the converters and controller to extract power from the turbines. While we have recorded spikes of power, we can’t achieve sustained power output. Closer inspection of the data reveals that the controller and converters do not communicate properly, which prevents the generator from being properly loaded in order to draw current. Once again, we are faced with an obscure problem regarding the operation of off-the-shelf electronics. We are working diligently to solve this converter/controller problem and are seeking expert opinions and suggestions to figure it out. In short, the funnel performance is satisfactory, the turbines are running, but now we need to solve the 3rd party off-the-shelf converter/controller problems to extract the power.

Q5 Was it a mistake to not develop your own turbine and system? Have you made mistakes? If so what?
The standard process to commercialize is to build alpha, beta, and pre-production units and fully test the systems before the product is ready for full production and customer installation. However, that process is costly both in capital and time. The estimated cost for these steps was $150,000 to $200,000 million. However, in the current market environment, we have not been able to raise the required capital. The solution was to use an alternative approach that was lean and capital-efficient. In the heart of our approach was our partnerships with direct customers for building beta units at customer sites and refine the product in collaboration with customers. In addition, we licensed the technology to other companies worldwide so they can build beta units for testing in their local markets to achieve global commercialization.

Was our approach a mistake? If all would have worked out, the answer would have been no, but we have not advanced as planned due to lack of capital. We have not secured the minimum capital ($15,000) to hire the expertise to diagnose our problem with 3rd party off-the-shelf electronics. At the end of the day, we tried an alternative approach, and the lack of capital has haunted us.

Was it a mistake to go on that path rather than stop the company and wait for the day in which we could secure needed capital? Maybe it was. We know, however, that any innovative company has to discover its path based on available capital and required resources. Every company applies its own perspective to reach its own conclusions. We decided not to fail by failing to try.

Q6: A recent article says, “SheerWind-Invelox—Is the End Nigh for Another Ducted Turbine?”  Is it?
SheerWind has had its challenges and ran into issues in the field, but we know for sure is that the SheerWind technology works; our problems have been with technological equipment purchased from others. Like a typical start-up technology, we have encountered delays when developing for the market. When developing game-changing technology like ours, the challenges and resistance to market entry increase greatly. In today’s social media and blogging environment, it is easy for uninformed outsiders to provide misleading information and prey on innovative companies by claiming ingenious expertise. These uninformed bloggers and trolls often reject any new idea in the market. The author of the “Is the End Nigh” article repeatedly preys on new ideas in the wind industry with a bias toward defending traditional wind technology rather than any science-based approaches to study the feasibility of new technologies, such as ducted turbines.

Q7: The author cites an article from 2014 that was written by another blogger to debunk your technology. What do you have to say to his claims?
The blogger did not debunk anything. He seemed not to understand the science supporting the technology and peer reviewed papers, and made a point of insulting five experts with PhDs in engineering, each with more than 30 years of experience. We choose to ignore the naysayers with no engineering or scientific argument, as they seem to negatively challenge new technologies in hopes of getting recognition while using innovative companies to drive traffic to their websites. It is the same people who dismiss all new wind technologies and claim to know more than hundreds of experts working on breakthrough ideas to improve the world and peoples’ lives. We expect to encounter naysayers. What is difficult to understand is defamatory name calling and outright slander aimed at hard-working scientists and engineers. Based on the blogger’s faulty definition, any risk taking innovative scientist is a “crackpot inventor”. Taking the risk to bring innovative ideas to market is why the United States of America is the world’s technology leader. It is understood many may not succeed but the few that make it, have had a meaningful impact on our lives.

Q8: The article says the National Guard gave SheerWind until June to get their three contracted devices in operation. Did that happen?  Where did the writer’s information come from?
Most of the information in the article is simply false, misleading, and dishonest. The writer claims to have tried to contact SheerWind or our partners for comment. We would have known if they would have attempted to contact us. Credible reporters and journalists are up front; they introduce themselves and ask questions. They also tell complete stories rather than creating their own false or misleading narratives based on photos of one of our first demonstration unit that was hit by a severe storm. It doesn’t make sense to write negatively about all innovative renewable energy technologies and yet claim to be great fans of renewable energy.

Two of our units are not to be commissioned until the Army National Guard provides electrical connections to both sites. That has been the reason for the delay. As for the Fort Custer project, it was pre-commissioned after resolving issues not related to the INVELOX technology.

Q9: Another recent article sites the end of the ducted turbine company Ogin, including a blogger calling the  inventors “crackpots.”  Why do you think they failed?
It is not for us to speculate on why a company failed, but we do know that ducted technologies work. We were all disappointed to see Ogin Energy close its business. People who worked at and invested in Ogin are top engineers, scientists, and investors from credible institutions and firms. Calling innovators “crackpot inventors” comes only from lack of regard and knowledge. Ogin’s technology came from a spinoff from the aerospace community surrounding the Massachusetts Institute of Technology. The Department of Energy has found that Ogin’s technology offers exceptional promise and has provided funding to the company through the Advanced Research Projects Agency – Energy (ARPA-E) program. Ogin raised over $130 million from leading venture capital providers and strategic partners. It appears Ogin’s investors decided to close the company due to excessive O&M cost and not lack of performance of the ducted turbines they designed. The writer of the article seems to believe that any risk-taking innovative scientist is a crackpot inventor. Taking risks to bring innovative ideas to markets is what made America.

Q10: Your technology is considered ducted. Why do you think SheerWind will survive?
In the case of SheerWind, we capture and bring wind down to the ground level. We eliminate many costly items, such as the tower itself, giant blades, yaw control, pitch control, gear box operation, nacelle, heat exchangers inside the nacelle, and related components. Removing those costly parts balance the cost of the funnel that captures wind and brings it to turbines at much higher speeds. Because all turbines are at ground level, there are significant savings in O&M. By magnifying speed, we can have higher availability and higher annual energy production. We are working diligently to bring this vastly improved product to market.

Q11: So what is the holdup? Why isn’t this being installed around the world?
First, we are attempting to change an industry. The companies invested in traditional wind will not easily change direction. We feel strongly that it is time to look at the problem differently, not continue to engineer larger and larger towers, blades, and turbines to produce more power. What other technologies get larger and larger to progress? Imagine if computers or cell phones got larger and larger to increase performance, capabilities, and power as the technology advanced.

Second, as most start-ups, we need support and capital. Enough capital would allow us to move faster. Our current team works because they understand and have a passion for the impact this technology can have on lives, the environment, and the future. With sufficient capital, we could hire, grow, and commercialize faster.

Q12: So capital is the issue. Why haven’t you been funded?
We have great support from our 42 current investors and appreciate their commitment. We are now at the point that angel investors cannot provide sufficient capital. We need an infusion of meaningful capital instead of just enough for boot-strapping the company. Our lack of capital has caused challenges with the Fort Custer unit. Everyone is waiting for the Fort Custer unit to produce power. It is frustrating for all of us to see the turbines turning to the point they should be producing the expected amount of power, but due to what today seems to be a software or electrical issue from 3rd party off-the-shelf components, we can’t deliver meaningful electrical energy to the grid yet.

Q13: Why do you think SheerWind will survive when others (like Ogin) did not?
We have had this subject on our web site (see FAQs 17 and 22 at here: technology/faq-technology) since 2012. Historically, while most people agreed on the performance of ducted turbines, the challenge has always been to bring the cost low enough to be competitive. The Ogin team had the right idea by speeding wind up using ducted turbines, but when placed on the top of a tower, there is no cost reduction. Adding a duct on the top of a tower adds to the complexity of the yaw control and O&M.

Q14: What do you feel has been your greatest success and greatest challenge to date?
Our greatest success has been to team up with companies around the globe to accelerate commercialization of the technology. We have been able to open meaningful discussion about what really matters in wind power generation, and what can be done to make wind power a leading contributor to our global electricity needs.

Our greatest challenge has been the delays in showing we have a viable commercial product.

Q15: What are the next steps for the technology and for SheerWind?
Once we have the current electronic problem solved at our Fort Custer unit, we will move on to optimizing the system. After we show we can generate meaningful power (about 100kW) from a 3-meter rotor in a low-wind-speed area, the market will see the full potential that the technology offers. We have several experts in the area of Computational Fluid Dynamics (CFD) working on the geometry of the funnel to improve the performance and have found multiple variables that will increase the performance of the INVELOX funnel technology.

It can only get better from here. As a colleague in the Netherlands reminded us, the Wright Brothers first flight was only 120 feet; if it was not because of the risk they took, we would not now have jets flying us around the globe. Imagine our world if we didn’t have those who have taken risks to bring better technologies into the world.

Ducted Turbine Research References

When it comes to physics of the ducted turbines, researchers and scientists around the globe have concluded since the early 1900’s that ducting turbines increases energy output.

Below is a short list of work by researchers, professors, and business community.

  1. Kenneth Visser (Professor, Department of Mechanical and Aeronautical Engineering, Clarkson University, Potsdam, NY, November 2009), “Wind Tamer Turbine Performance Report”.

Quote 1: “In general, it was observed from the numerical estimations that the WindTamer turbine can produce approximately twice the annual energy output for a given swept rotor area than a conventional open rotor design.”

Quote 2: “These data above indicate that the WindTamer is capable of Cp values in the 0.6 to 0.8 range, well above that of small wind turbines on the market today by almost a factor of 2, and as has been shown, above the Betz level for an open rotor. As will be shown in the next section, these values are quite close to those predicted by the design code, mRotor used at Clarkson.”

Quote 3: “The 52 inch rotor WindTamer is estimated to generate about 3,030 kWh per year, roughly 2.5 times more energy than a comparable open rotor of the same diameter, which yields 1220 kWh per year.”

  1. C J Lawn (Professor, Department of Engineering, Queen Mary, University of London, London, UK, IMechE 2003), “Optimization of the power output from ducted turbines”.

Quote 1: “An enhancement in the power coefficient of more than 30 per cent over the optimum for an unshrouded turbine can be gained, provided the turbine resistance is reduced appropriately by choosing a more lightly loaded design.”

Quote 2: “Such an enhancement is associated with a 15 per cent increase in velocity through the turbine over the freestream value.”

  1. H. Al-Bahadly and A.F.T. Petersen (Massey University, New Zealand, 2013), “A Ducted Horizontal Wind Turbine for Efficient Generation.”

Quote 1: “Power calculations were provided for the ducted turbine and the conventional turbine. These provided a direct comparison that was referred to as condition 1 and condition 2. This showed a theoretical power rating difference of a factor of 17, it must be shown here that the theoretical power shows the amount of power that is available in the wind flow.”

  1. Ducted Turbines International (DTI), “Ducted Turbines Technology”, 2016

Quote 1: “A duct surrounding the rotor captures more of the oncoming wind, directing it through the rotor to increase the amount of wind energy the rotor sees.”

Quote 2: “While a proper duct design is key a performance increase, the additional cost is even more important in evaluating the cost/kWh of the turbine.”

  1. Belloni and R.H.J. Willden (Department of Engineering Science, University of Oxford, Oxford, UK), “A computational study of a bi-directional ducted tidal turbine”, 2010

Quote 1: “Compared to the bare disc a clear increase in both thrust and power coefficient is visible for the ducted disc.”

Quote 2: “Simulation results show that the turbine’s power coefficient, defined based on the rotor swept area, can be modestly increased through the use of the duct. The increase in power coefficient is accompanied by an increase in the overall thrust acting on the device.”

  1. Ogin Energy at Oginenergy.com

Quote 1: “The Ogin Turbine is different.  Its unique shroud design takes advantage of the latest advances in the aerospace industry to change physical airflow patterns through and around the turbine.  Annual energy output per kW of rated capacity is increased by 50%, while peak energy output from the ultra-compact rotor is increased by up to three times per unit of swept area.

• AMERICAN BIRD CONSERVANCY Can Wind Energy Be Bird Safe?:

Can Wind Energy Be Bird Safe?

READ FULL ARTICLE

Nearly every week, Kimberly Kaufman receives messages from birders and conservationists alerting her to new wind energy designs that bill themselves as safe for wildlife. The technologies come in all shapes and sizes and are in varying stages of development. Yet each claims to do one thing that conventional wind turbines can’t: harness the incredible power of wind without killing birds.

Taking a Different Approach with Wind

One of the new companies is SheerWind, whose Invelox technology harvests wind energy even in areas where airflow is minimal. Invelox captures wind by funneling it through tubes that “squeeze” the wind and increase its speed, much in the same way that putting one’s finger over a garden hose will accelerate the flow of water. Then multiple turbines located inside the structure generate power from the magnified wind speed.

 

•BATTLE CREEK ENQUIRER: Fort Custer prepares for climate change

AUGUSTA – The Army National Guard at Fort Custer is working toward energy independence and anticipating the effects of climate change.

For at least two years the guard has been preparing a plan to use alternative energy and to look at possible consequences of changes in the environment and climate.

On Tuesday the guard provided a public look at the plan, “Adaptation Planning for Climate Resilience,”  a Michigan Army National Guard pilot project.

During a series of meetings, the guard is attempting to look at long-term energy alternatives, recycling, and how it might respond to effects of climate change, according to Brig. Gen. Mike Stone, the Michigan National Guard assistant adjutant general for installations.

Stone told about 15 people attending the session Tuesday morning at Fort Custer that the guard is looking for ways to preserve resources and save money. “It is the right thing to do and it makes good business sense,” he said. Two of the most visible initiatives are a wind funnel designed to capture and increase air flow to turbine-generators and an adjacent field of solar panels.

•CLEANTECH CONCEPTS: Wind Harvesting Funnel Takes On Turbines

When it comes to harnessing wind for energy, Dr. Daryoush Allaei, a Purdue-trained Minnesota engineer and founder of SheerWind, thinks the industry is looking at the problem the wrong way. Current wind turbines are really only an optimized step beyond the old sail based windmills of Europe, passively waiting for the appropriate wind.

Instead, if the objective is power from wind, why not accelerate the wind for use in areas where turbines won’t work? Additionally, since conventional wind turbines kill approximately 573,000 birds annually, according to a 2015 Wildlife Society bulletin, it would be helpful to make them safer and usable in bird-filled areas like shorelines.

SheerWind’s technology is a cost-effective, high-performance alternative to conventional wind technology. By capturing, accelerating, and harvesting wind power in a funnel system called INVELOX, it turns traditional wind power systems upside down by first using a funnel to collect the wind, channeling that wind to increase its speed, and then delivering it efficiently to multiple turbines safely housed at ground level. It enables energy to be produced from very low wind speeds of 2 meters per second, in locations close to an end user — even on rooftops in urban areas —and eliminates the need for complex power and grid systems. Because the system is enclosed, it is bird-safe.

• CADDIGEST: Strange-Looking Contraption Is Actually a Wind Turbine

Renewable energy can come from the strangest places—and can be harvested in some of the most unique ways. This is truly evident in the recent launch of a somewhat Seussian-like wind generation station.

Generation Through Concentration and Acceleration

The funnel system—called INVELOX—harnesses incoming wind by channeling it through a funnel design that concentrates and accelerates the wind motion.

An illustration demonstrates how the wind power is concentrated throughout the system. (Image courtesy of SheerWind.)

SheerWind states that this design allows for wind to be captured at speeds as low as 2 meters per second—and that it is structurally compatible enough to be built on urban rooftops.

According to an April 2016 report, the INVELOX can increase wind speeds by 7 to 12 times and create winds as high as 75 meters per second.  READ MORE

• SCOOP BUS: New Technology Outperforms

An overseas test has revealed a technology available to New Zealand businesses is capable of producing results three times greater than traditional systems according to Pacific Wind program manager Reza Sehdehi.

This week, energy and engineering company Pacific Wind released results of a year-long study comparing the output of INVELOX to traditional wind generation capabilities discovering that not only did the INVELOX system outperform a traditional wind turbine tower it’s performance was triple that of traditional systems.

Rather than having turbines on poles in the air INVELOX systems place the turbines on the ground, using funnels to capture and direct air towards wind turbines.

Varying pipe widths in the system accelerate the wind utilizing the Venturi effect, a phenomenon used by Dyson airplane fans to deliver either cold or hot air to targeted areas.

This allowed the unit to produce 260% more electrical energy and 300% more power than traditional systems without any of the negative effects like wind noise or flickering.

“Make no mistake, INVELOX is the future of wind power generation,” says Sehdehi.
