Reasons to Invest

  • Two oversubscribed StartEngine campaigns with Reg CF. Named one of America's top 10 most fundable companies 
  • Our small wind turbines increase productivity by 20-50% when positioned close together
  • Strong IP portfolio with multiple patents granted and pending in multiple countries 

“Beauty combined with aerodynamic innovations that change the market for small wind.”

What does it mean to be one of America's most fundable companies?

 Pepperdine University Business School picked 20 out of 4500 companies as the Most Fundable Companies in America after an intensive review of the people, financials, and business plan, followed by interviews and background checks. After that, the public was asked to vote for their favorites, and Flower Turbines was in the top 3.

They picked companies using the criteria a venture capitalist would use to evaluate an investment. Here is a link to the site and here is an explanation of what it means from a venture capital point of view.

We believe this Reg A round of fundraising will accelerate our sales and growth so that we can achieve that prediction.

The Problem

Until now, the small wind sector of the renewable energy market has lagged behind solar

We believe there are two major problems preventing the small wind sector from heading toward the trillion-dollar mark.

  1. Typically, low noise and high efficiency do not go together as most small wind solutions have to compromise on one of these two fronts. As a result, this makes them unusable for most areas where people live and work.

  1. Wind turbines cannot be placed without interfering with each other's wind flow.

Additionally, there can be problems including the safety of birds, physical appearance, and cost-effectiveness. The aerodynamic interference of one turbine with another means they have to be widely spread, resulting in lower cost-effectiveness in settings where most people live and work.

Until now, in our view, smaller wind turbines have not provided a viable solution.

Another global problem: The growth of e-bikes is limited by the charging infrastructure.

The Solution

An entirely new type of small turbine

Flower Turbines has addressed the problems of the past with technology improvements. The turbines have less turbulence, more efficiency, and work together in a way that no one thought vertical axis drag-type turbines could. We are also disrupting the market by combining them with a beautiful design that makes people proud to own them.

Flower Turbines feature a cluster effect that causes one turbine to make its neighbor perform better. One turbine makes its neighbor perform 20-50% better as in the graph below —enabling a better solution: slightly more cost-effective than solar in a windy area, but hugely more productive per square foot. 

In the illustration below, red is the highest velocity, blue is lowest, the wind comes from the left, and this is a horizontal slice through the middle of the turbine with the shaft in the middle. Note that as the wind enters the turbine and reverses direction in order to hit the second blade as well (call it two for the price of one!), the illustration reaches “red” speed in the middle. The higher the effective speed when the wind hits the blades, the more energy the turbine produces. The red area of increased speed to the side of the turbine shows why the cluster effect works.

This is a huge advantage for Flower Turbines in places where space is limited—close to people, buildings, and parking lots. And it accompanies solar beautifully, because using both together means energy during more of a daily and seasonal cycle, thereby saving on costly battery storage.

*This image is an example of one of our models.

We have an additional product line of on and off-grid e-bike chargers, some of which are powered by our wind turbines.

The Market

Small turbines are projected to hit a CAGR of 17.4% over the next five years

The expected revenue from the small turbine sector is projected to reach $400M in 2024, growing 42.5% in just five years. This level of growth is expected without factoring in the effect of our product entering the mass market.

The market report states the following:

"The global Small Wind Turbines market size is expected to gain market growth in the forecast period of 2020 to 2025, with a CAGR of 17.4%% in the forecast period of 2020 to 2025 and will expect to reach USD 316.7 million by 2025, from USD 166.6 million in 2019." Flower Turbines is clearly in a high growth market and has the opportunity to increase the size of that market and its growth rate by specifically targeting the underserved markets of the location close to people and close to or on buildings because of the combination of quiet and efficiency.

We believe our technological improvements to small wind will eliminate some of the past barriers in the industry, allowing us to contribute to further market growth. With these changes, we think that small wind can grow on a similar trajectory as solar.

Additionally, Solar PV experienced large growth while being in the public domain. But only Flower Turbines can produce a Tulip thanks to our Intellectual Property.

Bloomberg predicts that wind and solar will power half the world's grid by 2050 and receive $9 trillion of investment. We hope Flower Turbines will be part of that. Additionally, Flower Turbines has entered the exciting market of electric charging, one of the top trends in cleantech.

Our Traction

Our "cluster effect" has demonstrated success

In our decade of development, we have had success in pitching our design and product to investors and accelerators all over — we were one of the 3% chosen to participate in Dreamit Venture's first Urbantech Accelerator, we were among the winners of the US-China Innovation Forum contest, were chosen by PortXL Rotterdam as one of the 20 companies out of 1000 for investment and we won the 2019 Energy Award in the Netherlands. 

We have demonstrated the successful execution of the benefits of our ‘cluster effect’ and recently started the manufacturing. In addition to this, our achievements speak for the power of our technology.

  • Won an innovation loan from Rabobank, a vote of confidence from a top bank in Europe

  • Acquired and developed a product line of wind-powered electric bike charging stations

  • Set up a manufacturing supply chain close to our entry market for the EU

  • Won a national competition in the Netherlands, whereby a city is paid to buy one of our turbines

  • Chosen as one of the top 45 inventions in the history of Israel (the technology was developed there before incorporation in the US)

  • Set up our own small wind tunnel and research facility in Rotterdam

  • Won contracts and a tender in the Netherlands.

The charging station market depends on sales of electric bicycles and scooters.  A recent report from Deloitte estimates that 300 million electric bikes will be on the world's roads by 2023, which is 50% more than in 2019.

With more sales in process, we are also planning manufacturing and development in the US. As of September 2020, we have signed a contract for the development of our own brand of motors and we are also developing our own brand of charge controllers. These initiatives will result in components that fit our demands exactly and lead to lower costs.

What We Do

Building a great global wind technology company

The last round of funding enabled us to develop our team and high-quality supply chain in the EU, with mostly Dutch manufacturing. With this next round of funding, we’ll be concentrating on expansion particularly in the NorthEast region of the US, and manufacturing in the Midwest.

We see the market of electric vehicles on-grid and off-grid charging for bikes and devices as one of our large future markets in addition to selling the turbines for grid electricity. 

We also believe in our part in saving the planet by creating technological improvements that will make our products useful choices. Our goal is to provide 5% of electric power in most major markets within 20 years. If we can achieve mass production through this next funding round, we will try to achieve a growth trajectory similar to that of solar.

The Business Model

Creating the future of small wind farms

Our technology enables a new model in small wind. The fact that we can cluster the turbines means a small wind farm sales model, which is cheaper for the customer. Now, a mall or school building can have 100 turbines on their roofs or in their parking lots—the same on a lesser scale with residences. 

As Flower Turbines grows, it plans to sell not just turbines, but also electricity. We believe, from our own assessment, the US commercial market alone is a total potential market of $225 billion and the residential market is another total potential market of $50 billion.

We have also diversified our revenue generation through our electric bicycle charging product line.  This enables us to sell products in non-windy areas and where the grid electric price is very low.

 *Images are computer generated demo versions.

Flower Turbines is creating partnerships that will lead to new markets for our turbines. Here is one current proposed partnership using wind and solar together for greener transportation.

How We Are Different

We make small wind turbines with a mass production and installation model

An indication of the efficiency of our Flower Turbines is that they are able to begin generating electricity at a wind speed of just 1.2 m/s (industry standard is 3 m/s).  This conclusion is based on testing data in a low wind environment.

If you were to place our turbines next to the average competitor with 3 m/s wind, the large model Tulip will already be producing 30 Watts of electricity as the competition is first beginning to rotate.

Our ‘cluster effect’ is also one of our key advantages, as it allows us to scale wind farms and enter urban markets with tight spaces. 

The carefully crafted design of the Tulip is so aerodynamically efficient, it is actually able to take the wind entering the turbine, reverse its direction, and point toward the second blade at a higher speed than the initial wind outside.

Pictured below is Dr. Farb at a contract signing after Flower Turbines won a tender from a city in the Netherlands

The Vision

Building a Great Company With Environmental Responsibility

We believe in our part in saving the planet, not by asking for subsidies, but by creating technological improvements that will make our products useful choices. Our goal is to provide 5% of electric power in most major markets within 20 years. That is a significant goal and a significant impact on the planet.

Fulfilling our business plan requires an up-front investment, but we believe that the quality of our products and demand for more will result in potential growth once people become acquainted with first installations.

       To our investors and followers,

Flower Turbines continues to make engineering advancements. We have filed three provisional patents on wind turbine electronics in the last few months and are trying to make important innovations in small wind electronics just as we did for aerodynamics.

The goal is to produce a high-efficiency power electronics controller that will serve both as a battery charge controller, as well as a buffer between the turbine and a solar grid-tie inverter. Our engineers have designed and assembled electronics to improve efficiency and are in the process of testing and data collection.

Flower Turbines is also testing a small generator and charge controller under development for the past year.

 Flower Turbines has also selected and acquired equipment for future electronics development and testing including soldering equipment, power supply, electronic load, current clamps, and multimeters.

Flower Turbines Signs MOU with Texas Tech

8 months ago

Flower Turbines is excited to announce its partnership with Texas Tech University’s Global Laboratory for Energy Asset Management and Manufacturing (GLEAMM) to research the benefits of using Wind Power. We will place several turbines on site, in Lubbock, Texas, at the Reese Technology Center. 

Our collaboration will focus on joint sources of grant funding to do projects in microgrids and other sustainable energy projects. Flower Turbines will collaborate with GLEAMM researchers to improve the electric grid and understand the effects of renewable energy sources utilization. This endeavor enables and accelerates successful commercialization by providing a research platform for academic and industrial research on new electrical grid technologies. 

The State of Texas created GLEAMM with a $13 million investment in 2020. The facility is a place for businesses to economically test pilot ideas, certify and commercialize products while collaborating with world-respected researchers. 

Texas Tech University is recognized as a “Tier One” Research university by Carnegie Classification of Institutions of Higher Education. The university is home to 40,000 students and dedicated more than $84 million to research last year. 

Flower Turbines is proud to call Lubbock, Texas, our home for manufacturing and customer service. We employ several Texas Tech alumni, and look forward to growing our business on the windy South Plains.  

Deeper Dive into Turbine Efficiency Data

8 months ago

We compiled the data from two mid-size turbines with thousands of data points measuring wind speed and power output (from the generator directly, not after passing through an inverter, which introduces other issues, and the two turbines had slightly different equipment). As background, our Tulip is a Savonius type of turbine with several improvements. Most experts will tell you that a Savonius turbine is at most capable of 15% efficiency. Now look at the data below from the Flower Turbines, even at the size of blades only 2 meters high and 1 meter diameter. At a speed of around 2 meters per second, the efficiency is around 15%. and rises as the wind speed increases from 1 to 5 m/s to around 28%. It is normal for turbines to increase efficiency as wind speed increases. What is interesting for us is that Flower Turbines reaches the efficiency level of small horizontal axis wind turbines, around 30%, but it does so with no noise and with starting to produce electricity at lower speeds. At the point that our turbine reaches 20% efficiency, the horizontal axis turbines are just starting to move. So here are the conclusions: 1. We really have an innovation in terms of efficiency. 2. Our turbines have a big advantage in lower wind speeds, up to average 6 m/s, which is really the majority of places around the world. 3. Once we can bring down our price through mass production, we have a product with even more advantages.

Customer Comment on Lack of Noise

10 months ago

This is a customer comment that confirms our recent measurement of a noiseless turbine: "During storms we did several times a sound test. It was nice that the sound of the wind was in all cases stronger than that of the windmills. Or in short: you don't hear them. Which is especially in a heavy populated city like Amsterdam of great importance" Sjaak Besselink, Municipality Amsterdam

Noise Testing Results

10 months ago

We just had a third-party noise report. The full report should be on our website this week. The major points are: 1.    There was no sound of the turbines distinguishable from the background noise. 2.    In fact, the background noise of 45 decibels decreased, after passing through our turbine, to 39 decibels at 4.5 meters and 32 decibels at 10 meters . This is something we have predicted theoretically because, if the turbine adds no or minimal turbulence, the energy consumed by the turbine reduces the energy carrying the sound. This is very significant. We are in the middle of a proposal to a large railway company about using our turbines both for energy and for sound reduction.

The Large Size Turbine and Company Strategy

10 months ago

The entry of our large size turbine into the market in Europe and soon the US is an important strategic step. From the beginning, we saw our major business plan as the sale of larger size turbines to corporate and government clients such as mall, school, and factory parking lots as the biggest profit maker for Flower Turbines. This is because efficiency, cost-effectiveness, and profits increase with size. Our evaluation of our market as being a trillion-dollar market is largely based on the potential to make millions of urban/suburban wind farms, enabled by the cluster effect to put many turbines adjacent to each other, on parking-level properties in windy areas around the world. We have been building experience with smaller versions and allocating money from funding to enable us to build larger sizes.

What Investors Are Saying About Flower Turbines

11 months ago

We know people love our turbines as art combined with energy. That’s not the only thing they love. Here are some comments from our investors. Thanks to them, we just hit $3.5 million in investments for the year on Startengine.

Wow! Wow! Wow! Fifteen meter version is... Wow! And having the FT advantages of quiet, bird friendly, and generating power starting at a lower wind speed than competing products... makes me smile.-- I am so happy with the company: its people, its strategy, its momentum, its use of funds, and its potential.--Neil

Thanks for creating such a great product! So much potential to grow! Wind farming is still such a huge market and I believe a product like this might be able to revolutionize how most individuals and businesses harness this energy. Thank you and keep up the great work.--David

Keep up the good work, the world is waiting for this breakthrough wind technology.-- Isaiah 

I am excited to join your investor team. I thought you might be surprised to learn where I heard about your company! I teach English as a Second Language online all around the world; there is a website that I use with some of my students called Engoo which has various news articles written for English learners. One article I read with a student this past week was about your wind turbine company, and I just had to research it later. Wow, I was impressed and couldn't wait to take advantage of being a part of it! Totally hoping all the best for you. -Laurie 

I invested for me and my children's future, and their children.—Jessica

Great Results From Turbine Data—Product Validation

11 months ago

This data is from a grid-connected installation in the Netherlands. We used our “3-meter” medium turbine with blades approximately 2 meters high and 1 meter in diameter. 

A plot of average wind speed on the x-axis and power in watts on the y-axis gives the attached power curve.


This graph is based on 3064 data points of average wind speed computed at an interval of 15 minutes each. The spread in values is likely from the different gusts. Taking the average readings, the efficiency is 23% (Cp=0.23) with a range of 17% to 31%. 

How does this compare with traditional wisdom about small wind turbines? Even the 17% is better than what experts thought was possible for this category and size of wind turbine. 

Since efficiency increases with size, it is reasonable to expect that larger sizes such as our “6-meter” model will have average efficiencies in the 30+% range.

What is the speed at which power, even a little, starts to be produced?

Here is a sequence in time when the wind speed rose from zero; first column is wind speed, second is electricity in watts:

























In this sequence, the speed at which the turbine first produced electricity was at 1.41 m/s. There is not electricity worth using at this speed, but at least the Flower Turbines started producing before other ones start, usually above 3 meters per second.

Combined with the advantages of low noise and beauty, this turbine is a solid competitor to lift-type small turbines. In addition, the cluster effect enables them to produce more energy per cross-sectional area of the installation than lift turbines, when the installation area is considered as a whole. (Technically speaking, that is not efficiency, but rather greater production of power due to an aerodynamic effect. For the purposes of calculating expected power, we can treat this effect as if it were greater efficiency, in which case, a larger Flower Turbine would have an efficiency of 40-50% and higher than that of the more common horizontal axis turbines.)

More About Joining Startengine Secondary

11 months ago

Having a secondary market open for our shares is good for the company, and good for investors for whom liquidity is important. One potential negative is that we would prefer our investors to purchase more shares by investing new money so we can grow.  The compromise might be that we open the secondary market for small periods of time to enable those who need the money to cash out. Usually, investors in a startup expect that they won't see liquidity for their money for five or more years. This eliminates one of the risks of startup investing and should be an overall positive for the company. Everyone following these messages will get equal access to information about when we will open for secondary trading.

While the company has signed a quotation agreement to trade the securities offered on StartEngine Secondary’s new alternative trading system (the “ATS”), a company which intends to be quoted on the marketplace will be subject to certain requirements which the company may or may not be able to satisfy in a timely manner. Even if a company is qualified to quote its securities on the market, there is no guarantee an active trading market for the securities will ever develop, or if developed, be maintained. You should assume that you may not be able to liquidate your investment for some time or be able to pledge these shares as collateral.

Flower Turbines Joins Startengine Secondary

12 months ago

Flower Turbines has now joined Startengine Secondary. To summarize, this means that we may be able to give investors an opportunity to trade their shares. This allows those who need their money back sooner for whatever reason possibly to have liquidity for their investment. The lack of liquidity has traditionally been one of the downsides of early stage investing. Startengine has made a significant step forward for the equity crowdfunding industry and we are glad to join them. The next update will give some more information on the strategic significance of this milestone. 

Disclaimer: A company which intends to apply to list its securities on the marketplace will be subject to certain requirements which it may or may not be able to satisfy in a timely manner. Even if a company is qualified to quote its securities on the market, there is no guarantee that a demand for these securities will exist. Even if a company does meet the requirements for listing its securities, we do not know the extent to which investor interest will lead to the development and maintenance of a liquid trading market. You should assume that you may not be able to liquidate your investment for some time or be able to pledge these shares as collateral.

This shows the manufacturing PCT international patent discussed a few updates ago in actual use. Also, a few updates ago, we showed the problem of connecting round blades to the shaft without causing ripples or loss of strength at the point of connection. The photos below are from the first blades produced the new way according to our patent.

Our patent involves making pockets of similar thickness to and continuous with the main part of the blade. We embedded something that looks like a thumbtack inside that pocket and coated it on the outside (not a necessary step, but it looks nice) with fiberglass. The first picture is an outside view of the blade. The second picture is an outside view of the blade with the coating over the pocket. The third picture shows the inside of the blade, where it can connect firmly to a strut without causing ripples and areas of weakness in the blades.

New Flower Turbines Generator

about 1 year ago

Flower Turbines has started producing its own electronics, first for the smallest turbine size. We produced 10 generator prototypes for testing and use in our products, like the ZW bike charging pole. They are specially designed to be built with high quality materials and have voltages capable of working with low wind speeds. We can also sell it to other companies in the future. The picture below shows the testing and then a closer view. Rated production: 100 watts. It goes up to 300 watts. One of the stress tests was spinning it at 250 rpm (everyday use expected to be in the range of 25-100) for 30 minutes, and the temperature went up by only a few degrees. This mass-produced product cost will be below that of current Far East prices after we finish the initial investment in tooling.

Bright red wind turbines installed at Roodhart Rotterdam

about 1 year ago

Look at the fiery red colors of our wind turbines! 

This week, we have installed two beautifully colored wind turbines on top of the industrial complex of Roodhart in the harbor of Rotterdam. 

With two more Flower Turbines to be placed here soon, Roodhart’s sustainability ambitions cannot be overlooked. The turbines have their beautiful company colors – a passionate bright red, as the company’s name means “Red Heart” in Dutch and symbolizes the passion and the name of this family business.

As a European business with its roots in the Rotterdam harbor, the company specializes in industrial pumping systems and mechanical seals. Like us at Flower Turbines, the people at Roodhart put great value in sustainability and feel that their industry should aim for a greener world. We at Flower Turbines couldn’t agree more. To show this to the world, our vertical wind turbines are a great contribution to Roodhart’s sustainability ambitions.

Important Step for Important Patent

over 1 year ago

Flower Turbine’s patent on the ratios of the different parts of our Wind Tulip turbines recently received an acceptance of novelty and inventive step under the Patent Cooperation Treaty in the “International Preliminary Report on Patentability”. This patent is an important basis for our creating more efficient and simultaneously quiet turbines; the concept is that certain blade relationships, air spaces, tip speed ratios, etc., when correctly combined, make its category of turbine substantially more efficient than it was before. This is what we were waiting for before submitting the patent for national phase in important countries or groups of countries throughout the world. (The patent was already submitted in Argentina, which is a large country not a member of the Patent Cooperation Treaty.)

What we’re doing with the campaign money already

over 1 year ago

Our deep thanks to our wonderful investors who are making this round successful already. The money coming in already enables us to initiate some important things:

1. We are developing the electronics for our turbines at a faster rate. This is important because if we can exactly match the generators and charge controllers to our turbines, it allows our aerodynamic innovations to shine better. Currently, we are using off the shelf electronic products. So now, we will have more efficient products, at a lower cost than those made in developing countries because of the use of molds and tooling instead of hand wiring and so on, with supporting a labor force in the US where the workers are paid a solid wage, with better features like corrosion proofing at the basic production level instead of later coatings and seals, and we may even be able to sell the products to other companies.

2. We are planning improvements to our e-bike charging product line that will make them higher quality and more useful.

3. We are interviewing manufacturers for a second site of manufacturing, in the US market in addition to current production in the EU market. That will take money for early production runs at low quantity.

4. We have some patent filings coming up soon.

In a future update, we’ll talk about plans for using future money that comes in after this.

Data on Low Wind Speeds

over 1 year ago

The following graph is based on data logged over several years at a low wind speed area compared to an average wind turbine. Points to pay attention to:

1. Most wind turbines start turning at 3 meters per second. This Wind Tulip started to produce power at just over 1 meter per second.

2. This is smaller and an earlier design than our current large model. So we expect even better results from our current large version.
