Mathematically the MAXIMUM energy in the wind (in kilowatts) for 1 square meter is 0.0006 * wind speed CUBED. So for a blade of 1m^2 and a wind speed of 2m/s (average city wind speed) you have kW = 0.0006 * 2^3 , equalling 0.0048 kilowatts, or 4.8 Watts. These turbines might be 10-20 efficient. So you will need a 100-300 hundred square meters to get enough power to power a home.
@@markdee3506 True. But from what I gather it is controlled by electronics. Surprised it is not controlled by simple mechanics, like a governor on a steam engine (I would have thought more robust).
This looks like a wonderful idea and I would love to install one at my place. I just hope they're not ridiculously priced like all the other homeowner sized wind turbines.
I appreciate that your blades open up and close depending on wind volume. From my old memory the water pumps here rotated from inside a drum with openings either side, and the drum rotated to accommodate wind direction changes, and excessive wind speeds.
These are definitely a work of art! I am an artist and I'm really excited about the artistic possibilities. I could imagine a wind park that is also an art installation. Turbines of various sizes, painted in various colors and patterns. When they're all in motion, they are absolutely hypnotic!

@@HarmonyTurbines Why can't you see the other thing hiding in the open !? Savants see something very spicy and you're all absolutely oblivious 😂 Be very critical of those trying to talk down cheap efficiency ! 👍🏻
Amazing! I love the concept, I’d love to see more research done on this mechanism. I appreciate how your design is both visually appealing and very functional. Incredible work!
While the design looks amazing it has so many moving parts the cost to manufacture will be high which has always been the down fall of the many wind turbine start ups over the years for the small amount of power they produce (even ones far more simply designed that this) they end up 'turning' payback into a decade affair. Its just as likely to need more money spent on repairing it in that time. All that heavy spinning steel needs to be mounted somewhere safe, so thats another significant expense, all this doesn't stop me wanting one so I hope they prove me wrong :)
My thoughts exactly! I call moving parts "points of failure" because that's what they are. The expenses are going to shoot through the roof. If any politician will go for these - follow the money! Corruption seems to be the ONLY way to go.
Just looking at this for one second says it's probably uneconomical. All those gear tooths and loots of metalwork are just for the upper part. I have designed and overseen the creation of machines and factory lines, and I can assure anyone that this approach is expansive.
A lot of similar parts mean cheap production. When you choose materials wisely they are no paint of failure for some decades. Also both, the rod to control the opening and the main rod are completely to the bottom, so there is no extended electronics. This is a very clever design. I hope they will find a way for lightning, these things are quite high.
This competes with OTHER wind turbine designs. These designs have many more moving parts already. Safety is an aspect that can make part numbers (and costs) explode. A huge problem, as you point out. A design that intrinsically nullifies the most annoying danger for wind turbine failure? That's very good. >> Better than many other turbine designs in that regard. On part numbers... What I could see in the video had less 'unique' parts than many toys. The 'unique' part is important, since that is what stands in the way of mast production. Not the absolute part number. >> Okay Bad. What I dislike is the open gears. These things get dirty, damaged, clogged up and that can stop the opening and closing process. The very process that's the main selling point for safety and effectiveness. >> Bad.
Looks like a variable Savinious rotor to me… plans in mother earth news back in the 70’s-80’s… vertical wind turbines can be better at harnessing gust energy, but a higher spinning mass negates some of this possible gain. The fixed savinious was self starting and tended to be self regulating as the advancing bucket shadows the capture bucket more and more as speed increases, so it was virtually impossible to overspeed them. I am guessing the variable mechanism is an attempt to increase low airspeed efficiency. The fixed savinious was able to generate a significant amount of torque, and they were fairly easy to produce out of old drums…
Hi Rronmar, check out this article. High windspeeds are indeed a problem for Savonius turbines. Our design solves the problems associated with high speeds winds. In fact it totally negates the need for a braking mechanism or dump loads. www.turbinesinfo.com/innovative-wind-turbines/ ...interestingly this article also speaks to the little known fact that bad data published many decades ago, has led to Savonius turbines getting a bad rap for the last 50 or so years! -We are looking to change the history books and begin showing people what a truly well designed small scale turbine can do! Perhaps we can even become the new standard in small-scale wind power generation? Time will tell.
@@cuckingfunt9353 Yes but closing (furling) is only needed in high winds so there's plenty of power during those times to sacrifice 30w for 10 or 20 seconds. The power is only needed while the furling mechanism moves. It is NOT needed to hold the scoops in place once the movement has stopped. We're spinning too fast, pull in a bit, re-assess, still too fast, pull in more, re-assess ...ok we're good now. The total power that took was maybe 30w for 15 seconds. The turbine will be making over 400w of power at these times so we're totally fine to steel a drop or two of power for the sake of safety.
Horizontally-oriented wind turbines have variable-pitch blades, which enables them to adjust appropriately to wind velocity. The major issue is mechanical complexity. Those burning turbines are a result of these systems failing. I guess the greater efficiency of horizontal turbines keeps them worthwhile.
@@jebise1126 Horizontal turbines can change direction, but the wind doesn't change very rapidly in the environments in which they are constructed. Generally: wide open spaces. It is true, though, that they're not terribly good for small scale generation in more cramped locations, like in cities, where the air might be more turbulent.
@Kelly Harbeson They can provide a great deal of power. The problem is that their status as "green" energy is dubious, given that the blades can't be recycled, they have a huge concrete foundation and it takes a lot of petroleum-burning equipment to do all the work.
@@goodbye8995 He means a spring working against the centrifugal force. At high wind speeds the centrifugal force keeps the rotor open, at low wind speeds, the spring overpowers it
This is amazing, I can’t believe you started this with your daughter. Indeed dreams do start small, I wish you guys all the best. I am subscribing, much love from South Africa🇿🇦🙌🏿.
It really doesn't. There are major issues with VAWTs, the primary ones being the stress on the lower bearing (think of the leverage), the poor start at low wind speeds (for savonius turbines) and the poor swept area.
No, the mathematics and economics does not add up. They will cost too much and be too inefficient. Do the mathematics and see you will need about 100 of them to power 1 home.
@@TerryClarkAccordioncrazy I agree with you - and it is clear from the responses from harmony that large-scale production is not their market. They are looking at the small and medium market, where their VAWT design definitely has some advantages.
The vertical wind turbines are economically and mechanically advantageous to us and the environment and as it is a work of art for I always believed sustainable energy could take over. I wish you all success in your endeavors.
Seems like an interesting solution to the problem. Not an investor (I have no money), but I am an engineering student. Out of curiosity, I have a few questions; answer as you see fit. How resilient is it to dust and plant fiber getting stuck in the furling mechanism and how often would it need to be cleaned if it were placed in a highly rural environment? If I look at 4:48, the plate that holds the blades to the central axis looks like a particularly vulnerable position to this type of wear/maintenance. How was the shape of the blades chosen- is it optimal for high-speed wind, low-speed wind, cost of manufacture, or some mix between? Is the furling system purely mechanical, or does it require a microcontroller to operate it based on a function of rpm; if it is a microcontroller, what wind speed is required to break even on power generation, and how was the furling function developed? Is the system vulnerable to sudden strong gusts? Is the system right-to-repair friendly, and if not then why not? What is the break-even time on energy costs, i.e. how long does it take to pay for itself?
Coffee, dust and plant fiber will need to be tested ...obviously being higher up will help but that's why we go from development into testing so we'll cross that bridge asap. You're comment about wear is over-rated. The amount of time the furling mechanism will operate in a month will likely be just one or two hours total. Mostly it will be for seconds at a time and the rest of the month it's just sitting static, rotating happily. But there are nylon wear (washers) in between places where friction would occur. Shape of blades is a very long story, not going to get into it now. Mechanical microcontroller for furling yes. Sudden gusts are smoothed out by the weight of the system itself acting as a large flywheel and it seems to handle them just fine from early testing. Yes repair friendly. We estimate about a 7 year ROI if you have good strong winds in your area and $0.15 or greater cost per KwH electric.

I’ve always liked the vertical wind turbines but most are set at a fixed blade, scoop or what ever it’s called. However your design with variable settings in relation to wind speed is a great idea.
David, It's finally coming to light that there has been a large disinformation campaign for decades against VAWT's and in general Savonius turbines, starting back in the 1950's or around there. Savonius Turbines are actually > 30% efficient without any helix twist or ribbed sections. A proper helix twist greatly reduces stress over the entire unit and smooths out operation as well. The main noted drawback noted was high wind vulnerabilities which our patented design now solves. Look at this ua-cam.com/video/pbtR6VG-gLw/v-deo.html
As a welding engineer in the 90's I had the chance to work on a energy project at a steam generated electrical plant, it very similar set up was used to govern the turbine speed, the main difference or improvement was in the impeller, the rear of it was shaped into a rounded tear drop there for reducing the return drag of the impeller, that improvement alone made it 16% more efficient and quieter! Also look into bamboo fibers and resin for making the impellers with a mold they can be made lighter and faster! Thanks Nate
@@HarmonyTurbines I doubt that there has been such a campaign but it doesnt matter. No amount of "bad data" can change the physical theory of it. Drag based turbines can never compete with lift based ones.
@@HarmonyTurbines And how many time do you cut and past that BS ? You stole the concept that existed for decades, and your implementation is probably one of the worst i seen, and now you claim that you know better than science ? Come on don't be silly.

Power is mainly determined by wind speed. For 1 square meter the MAXIMUM energy from the wind is kW = 0.0006 * wind speed CUBED. So for 1m^2 and average city wind speed of 2m/s you get 4.8 watts. Small city wind turbines will always be useless.

Great concept. Freaking brilliant to put it in the back of a pickup to create a simple wind tunnel. I hope I get to have one up here in montana someday.

Can the design cope with sudden onset of gusts of wind? Perhaps it could also benefit from being self-governing, that is closing up as wind speed rises even when the control fails to crank the motor.
I would expect that it can't. Gusts will pull the flimsy bones wide open, with how many moving parts it requires to function. My personal guess is that compliant materials will be the solution these problems are looking for. Not sure how, though.
Found your channel searching for solutions. I live on a small off grid business property in Doney Park AZ (suburb of Flagstaff). We have serious gusting wind here, nearly 365 days a year. Recently gusts topped 90 mph. Our power needs aren't substantial and our revenues are (currently) humble so cost is an issue. Do you have any cost projections on full systems (less battery bank)?
don't waste your time, this is a scam. And as of your concern, wind turbine benefit a lot of scale, so for individual installation it's not a very good solution. Would be much better to reach out to local community/authorities and collectively fonds one or more industrial sized one. To minimize battery usage the best solution is to pump water up (PHES) it's especially good if you are in mountain region. But unfortunately AZ is more flatland and not much water to spare i believe, so i'm not sure it will be suitable in your particular case. Big flywheel can be an option but here again scale is your best friend, i'm not sure it would make economical sens for individual installation, although industrial size one do show pretty good abilities. I know in Spain they explore molten salt solar panel and they would be a very good solution in AZ also as the climate is probably pretty close, but once again that only make sens in industrial scale as it rely on thermal mass (energy is stored as a volume so m^3 and lost is per unit of surface so m^2 so the bigger exponentially the better). Although i totally understand the will for independence (and actually share a major part of that desire) i'm afraid energy is one domain where community scale is king. The only interesting individual solution that i can think of (out of solar panel + lithium battery) in your case would be low/mid depth artificial geothermal, but it only cover thermal regulation part of the energy need (i.e. : heating/cooling air) and you need land area at least 10x your house living area. That show very good result in south of France, they install it under olive tree plantations.
Just ask your neighbors. Lots of people in Flagstaff have wind turbines. Otherwise, you can take a trip to the university and ask to see their renewable energy lab behind the engineering building. You can see the whole setup there and two different turbines. If you find a guy in Hawaiian shorts, he’s the one to talk to.

Could you add a concave cover on the wind catching side? I love the design but here in Maine that scoop is going to fill with ice and snow...and that's the time of year I'm going to need it most in a hybrid system. Perhaps a heating element?
Could probably just remove some of the lip on the bottom to maybe 10% of what it is and still keep some of the original rigidity. It could still flare at the base where the gear teeth are.
Having a bachelors in electrical engineering it doesn't seem that this produces enough power to power a small house let alone something industrial. There's too much of moving parts where energy is lost. That's what makes the 3-bladed wind turbines way more effective - low amount of moving parts.
@@lorenzo42p 02:13 On just 1 of these layers there is 8 points of contact where friction is created. That is the middle gear that touches those 2 half-gears on wings, and then you have poles that are in the center of those wings. Mind this construction is intended to not be fixed because the wind needs to open and close those wings automatically. (03:12 may be a better visual for this) 03:29 Because this is 4 layers it becomes 32 points of contact where friction is created. Then the whole construction needs to be held vertically by at least 2 points (1 on the top and 1 on the bottom) so as a whole there is at minimum 34 points where friction is created and that could drastically add up to major energy losses. Also the shape of the turbine is inefficient so you already have losses there. \ \ \ |
@@PurpleDuneEfa the gears on the wings only move when the wings are folding or unfolding. the wind does change a lot, so that could be often. it would need a motor to turn those gears, which is extra load on its generation. this type of wind turbine is known for having very low efficiency, as it fights against itself as you described. I can see dirt getting pressed into those gears and jamming up the whole thing. the wind tends to pick up and carry dirt, and there's a lot of the stuff out there in nature.
I'm impressed! If you would like to test one in summer temps that can reach more than 115 degrees with occasional very high gusty wind speeds (once reached 115 mph!) , you could put a prototype in my Phoenix, AZ back yard. It would be a unique yard decoration and attention getter! I would invest if I could.
I think that one element that contributes the most to its pleasing form, is the double helix. It's a foundational element of nature. The furling, or the opening and closing adds the spirit of life. The Yin/Yang symbol is also obviously attractive.
@@rom116kjv No it's not. Output-wise Vawts are totally inferior to HAWTs, and the optical attractiveness of VAWTs most of the time IS their only selling point.
Hi, I am poor and cant afford to invest in your company or even buy one of your generators. However, I very much appreciate anyone who makes the world a better place. As I am one of the people that lives on it. Thank you for your efforts.
Sorry to be a buzzkill but this is a scam. Your money is better off helping yourself anyway. Many people in the comments who are knowledgeable on the subject of wind turbines (myself included) are pointing out the fundamental problems with this design and the creator only copy-pastes the same bs conspiracy theory.

Nice! Its ingenios design should prove itself useful in increasing both durability and adaptability to access wider range of wind soeeds. Love the BOLD truck mount!

Nice looking and clever furling idea BUT...it's still only a Savonius vertical axis turbine. Not much torque, lots of inherent drag and all manner of mechanical fatigue stress issues. You can't re-invent the laws of physics, the power output of a wind turbine is directly linked to the volume of air that it can process and the velocity of that air coupled with the conversion efficiency of the rotor. What do your power curves look like? What is the swept area of your rotor?

I enjoyed this video and your concept very much. Thank you for sharing. Question : Do you have any plans in the far future to design a turbine for waterways using your open / close system.??
No plans at this time for a waterways system Maurice. But many people over the years have asked me about it. Yes it would work in water just fine though water does not often flow faster when you have flooding, just more volume so there's not much need for the furling capability in water applications.
I've probably watched 200 wind turbine videos and only today stumbled on this. Brilliant design and aesthetics, I look forward to watching from the beginning
And out of those 200 different wind turbine videos, how many actually came to market and is actually producing decent price per watt power? Many wind power scams have come and gone. Why isn't there any demo of this actually generating any power?
They can actually interfere in net a positive way. Their next video at 3:14 mentions a paper showing that vertical turbines in a grid pattern improve performance by up to 15% (spaced by at least three turbine lengths)
Interesting, we need to see the cost though as it's competing with solar, less complicated wind turbines and the grid which you can already buy renewable energy from for a low price.
Our goal is to sell them for 2500 USD shipped globally. We estimate about a 7 year ROI if you have good strong winds in your area and $0.15 or greater cost per KwH electric.

I suggest you propose this design for boats as well. When the turbine contracts, it can become a Magnus Effect cylindrical rotor. This only occurs when the wind is perpendicular or slightly diagonal from behind. At any other angle it would be open, not for propelling the boat, but for other needs on board.
Thanks we have been engaged with both Yacht and Catamaran manufacturers for about 2 years now looking at this. Once we're further along we will be working on units to do exactly this. We have even had Cruise lines contacting us so Magnus effect and Fletner rotors are definitely on our TO-DO list. :)
This is so cool!! A few questions. Have you thought about using composites for the air scoop to keep weight down and strength up? Also, is the unfurling mechanism electrical? If so are you using a slip ring to deliver power? And lastly can I have a copy of the stl files of your original models I kinda want to test out making a 5v device charger that can be carried around, or used in camping.
No matter what you do, Betz's law limits the available energy, making small turbines an uneconomic proposition. This will always be the case. Furthermore, the image of the burning turbine, supposedly caused by excess wind, is bogus. That fire would be down to failure of the mechanism, itself designed to adjust to wind speed, not the fact that the wind was strong. This silly design would be no less likely to have operating faults.
Reduce the torque the shaft has to deal with by having two sections of buckets spinning in opposite directions. Will reduce the amount of concrete needed in the base.
I'm not sure I understand what you mean. Assuming the wind is coming from the west, the pole will be pushed the opposite way, regardless of the direction of rotation of the bucket sections.
Significant step forward in the wind energy business. Major improvements: 1. Continous operation during wind storms. Non-interuptable power. Huge advancement. 2. Very little noise and no propeller flicker. Huge step forward. 3. This design is not a bird killer. Very important. Support these guys, this is the way forward!
I thought that vertical turbines, while they always look cool, have been pretty soundly debunked as having terrible efficiency, particularly compared to blade turbines. It's all because power is proportional to the active cross sectional area presented to the wind.

BS ! I call you patented liar. If you want to call out on scientific result it's simple set up an impartial protocole and put your numbers on the table.
A savonius rotor made from an oil drum will typically produce a bout 180 Watts at a wind speed of 10m/sec (Wikipedia). So your design is barely different so it won't produce much electricity: something you conveniently didn't mention. If you've spent 3 years so far then you haven't got very far. Sorry but you are backing the wrong horse with this project.
My understanding is that your comparison Sir, is not suitable to make solid point. The new type of blades are far more sofisticated than the Mother Earth type possibly could have been. Fair enough though, it was your opinion and not based on facts.
Love how many people are trying new energy options! This is great!! A guy from Japan, Atsushi Shimizu designed a turbine that will withstand hurricane winds and produce power.
Challenergy claims 30% efficiency, where a conventional horizontal turbine gets 40%. Vertical axis turbines have a severe problem. The reward-facing blades fight the foward blades, greatly reducing efficiency. I seriously doubt their 30% claim. I used to be president of a wind turbine company, so I know all the calculations. Unless you have some moveable components, you are simply not going to get that much efficiency out of a vertical axis turbine. Once you add complexity, you add cost and reduce reliability. You might as well go to horizontal axis and gain much higher power. Farms have been using horizontal axis for many decades to pump water. They are simple, reliable, and survive the storms you find on the plains.
I'm not interested in video footage of work in progress or fluff about saving the planet for a better future for the kids, I want to see HARD DATA, ideally in the form of a graph of Power Generated VS Windspeed. This is the bottom line. Thanks.
That will be coming as our 3 universities (Bucknell, PSU & Northumbria) begin their research projects on Harmony and our technology. Performance data and lots of other great stats will be fully published then.
@@HarmonyTurbines So in all the years you've been developing, you've never taken any basic power measurements and correlated them against wind speed? Not even a Prony brake style set up to measure raw mechanical power from the turbine shaft? If not, how did you become convinced you had a worthwhile product on your hands...? 🤔
@@saiello2061 the pony brakes that we looked at trying are thousands of dollars and need stationary mounting. This means we have to have wind come to us which is unlikely in our area with such bad winds here. To mount a setup on a moving trailer or platform is also very complex and dangerous as we found. If you have links to a simple inexpensive pony break, I'm all ears. We also tried 2x different off-the-shelf generators and both were terrible for our low RPM’S. So what sounds like a simple thing is really very complex. It's why we're now developing our patented generator. It's our best option for moving forward and getting all the data we want.
@@HarmonyTurbines Sounds like excuses to me now. You can make a Prony brake for next to nothing using some form of spring balance, a handheld tachometer and a few other bits and bobs. Lots of info online. As for a generator, there are so many options out there to get some sort of voltage/current reading it's hardly worth mentioning. With the size turbine you're experimenting with, I doubt you'll even be getting 100W shaft power out of it in a stiff breeze....
@@saiello2061 you be as angry and pissed off as you want. Scream at the top of your lungs and run around like a little girl. It doesn't matter what you're saying "should" be easy or quick to do ...it's not. We've had PSU and Bucknell both look at this issue with us and it's more complex than it appears at first glance. The way other turbine companies get their power ratings is NOT with a pony brake. It's with a properly sized generator matched (tuned) to the RPM's that they need to run in a wind tunnel at the rated windspeed. Then most of those ratings are thrown OUT the window because Underwiring Laboratories demands open air equivalent testing which negates wind tunnel testing and wall effect from compression. But who am I to tell you ...you seem like an expert and probably know all of this. For now the best I can give you is a "sorry you're going to have to wait" the data is coming as quickly as we can get it. No amount of insults from you or anyone will make them come quicker. By the way with the CRAPPY generator and charge controller we had we got up over 300w in our testing last year so your 100w prediction is off by a factor of 3x.
I am so glad you are out there trying. I wish you could publish the actual data on how much electricity your system can produce versus the conventional propeller/airfoil design. All large scale industrial wind farms are sticking with the airfoil design; they must have a good reason for that. I have read many explanations on why they use only 3 skinny blades, for some crazy reason I am not convinced, we need more blades and fatter ones.

This a great invention, as industrial engineer to be am proud of your work. Working with wind turbines companies to produce green energy is always my dream
Put a series of VAWTs on top of existing Electric Power Transmission Line towers, so that most of the height above ground is built, and electrical connection is mostly built, and right-of-way maintenance is already planned for and budgeted. It could also be done bit by bit instead of having to be mostly complete before being useful. At least, when building any new or replacement towers, take into consideration building them so that VAWTs can be added later.

As if praying is going to change the laws of the universe. Power is mainly determined by wind speed. For 1 square meter the MAXIMUM energy from the wind is kW = 0.0006 * wind speed CUBED. So for 1m^2 and average city wind speed of 2m/s you get 4.8 watts. Small city wind turbines will always be useless.
To power a home in an average city (wind speed about 2m/s) you are going to need about 120m^2 of surface area to be covered with these turbines (that should give about 500 watts) (more like 360m^2 at 30% efficiency ). The problem in cities is the low wind speed. Big turbines are built in high wind areas and are tall to access the stronger wind. The formula for the maximum wind energy from 1 square meter is: kW = 0.0006 * *wind speed CUBED* So for wind at 2m/s, and turbine area of 1m^2 you have 0.0006 * 2^3 = 0.0048 kW (4.8 watts). But efficiency will probably be about 10-20% for that design. Turbines always face the mathematical physics of *wind speed CUBED* you solve that by finding high wind speeds (tall turbines mounted on ranges, or where there is clear air out at sea).
Sabert00th if you have 2m/s winds at your home you would be denied approval for a Harmony Turbine. Sorry to break it to you. Coastal and boating customers will be our first target market. Extremely good winds with high incidents of storms and severe wind events. Perfect for our products.
Very interesting , I am from Puerto Rico where the weather is constantly changing and huracanes are a constant weather challenge. There is a critical energy situation in the Island and I think this type of Turbine could be tested there.
Turbines go round and round.
Therefore all turbines are revolutionary by definition.
Was going to say bearings, but you essentially beat me to it
😁
they rotate to the right....leftys are not industrial minded..
Be dum dum
That's what they will say in court! 😅
it would be nice to see the data on Size/rpm/watts output to compare to other VAWTs. Thanks
You don't get the data because it's not working.
Big companies only use propellers for their mill's for a reason.
@@CodeBallast Thanks I did see a video about how they were just developing their generator.
Mathematically the MAXIMUM energy in the wind (in kilowatts) for 1 square meter is 0.0006 * wind speed CUBED. So for a blade of 1m^2 and a wind speed of 2m/s (average city wind speed) you have kW = 0.0006 * 2^3 , equalling 0.0048 kilowatts, or 4.8 Watts. These turbines might be 10-20 efficient. So you will need a 100-300 hundred square meters to get enough power to power a home.
@@AORD72 well it will work well during a hurricane, so it's got that going for it.
@@markdee3506 True. But from what I gather it is controlled by electronics. Surprised it is not controlled by simple mechanics, like a governor on a steam engine (I would have thought more robust).
I was trying this 50 years back ! It's a variation of the anemometer. The furling is innovative.
This looks like a wonderful idea and I would love to install one at my place. I just hope they're not ridiculously priced like all the other homeowner sized wind turbines.
I appreciate that your blades open up and close depending on wind volume. From my old memory the water pumps here rotated from inside a drum with openings either side, and the drum rotated to accommodate wind direction changes, and excessive wind speeds.
I love this. Well done and congrats. I hope you get the full support you need to bring this to mass scale.
These are definitely a work of art! I am an artist and I'm really excited about the artistic possibilities. I could imagine a wind park that is also an art installation. Turbines of various sizes, painted in various colors and patterns. When they're all in motion, they are absolutely hypnotic!

@@HarmonyTurbines affordable? what about maintenance?
Amazing! I love the concept, I’d love to see more research done on this mechanism. I appreciate how your design is both visually appealing and very functional. Incredible work!
While the design looks amazing it has so many moving parts the cost to manufacture will be high which has always been the down fall of the many wind turbine start ups over the years for the small amount of power they produce (even ones far more simply designed that this) they end up 'turning' payback into a decade affair. Its just as likely to need more money spent on repairing it in that time. All that heavy spinning steel needs to be mounted somewhere safe, so thats another significant expense, all this doesn't stop me wanting one so I hope they prove me wrong :)
My thoughts exactly! I call moving parts "points of failure" because that's what they are. The expenses are going to shoot through the roof. If any politician will go for these - follow the money! Corruption seems to be the ONLY way to go.
Just looking at this for one second says it's probably uneconomical. All those gear tooths and loots of metalwork are just for the upper part.
I have designed and overseen the creation of machines and factory lines, and I can assure anyone that this approach is expansive.
A lot of similar parts mean cheap production.
When you choose materials wisely they are no paint of failure for some decades. Also both, the rod to control the opening and the main rod are completely to the bottom, so there is no extended electronics. This is a very clever design.
I hope they will find a way for lightning, these things are quite high.
This competes with OTHER wind turbine designs. These designs have many more moving parts already. Safety is an aspect that can make part numbers (and costs) explode. A huge problem, as you point out.
A design that intrinsically nullifies the most annoying danger for wind turbine failure?
That's very good. >> Better than many other turbine designs in that regard.
On part numbers...
What I could see in the video had less 'unique' parts than many toys. The 'unique' part is important, since that is what stands in the way of mast production. Not the absolute part number. >> Okay
Bad.
What I dislike is the open gears. These things get dirty, damaged, clogged up and that can stop the opening and closing process. The very process that's the main selling point for safety and effectiveness. >> Bad.
Coz they have some funds to “seed” inefficient “reinventions”.
Well done guys! a great idea, good luck, I hope it becomes a commercial success.
Looks like some great ideas and development, can't wait to see this in a fully working form!!!
Looks like a variable Savinious rotor to me… plans in mother earth news back in the 70’s-80’s… vertical wind turbines can be better at harnessing gust energy, but a higher spinning mass negates some of this possible gain. The fixed savinious was self starting and tended to be self regulating as the advancing bucket shadows the capture bucket more and more as speed increases, so it was virtually impossible to overspeed them. I am guessing the variable mechanism is an attempt to increase low airspeed efficiency. The fixed savinious was able to generate a significant amount of torque, and they were fairly easy to produce out of old drums…
Hi Rronmar, check out this article. High windspeeds are indeed a problem for Savonius turbines. Our design solves the problems associated with high speeds winds. In fact it totally negates the need for a braking mechanism or dump loads. www.turbinesinfo.com/innovative-wind-turbines/ ...interestingly this article also speaks to the little known fact that bad data published many decades ago, has led to Savonius turbines getting a bad rap for the last 50 or so years! -We are looking to change the history books and begin showing people what a truly well designed small scale turbine can do! Perhaps we can even become the new standard in small-scale wind power generation? Time will tell.
@@HarmonyTurbines well I only remember they were not an issue back then…
@@HarmonyTurbines So you have to apply power to the thing to make it close right ?
@@cuckingfunt9353 Yes but closing (furling) is only needed in high winds so there's plenty of power during those times to sacrifice 30w for 10 or 20 seconds. The power is only needed while the furling mechanism moves. It is NOT needed to hold the scoops in place once the movement has stopped. We're spinning too fast, pull in a bit, re-assess, still too fast, pull in more, re-assess ...ok we're good now. The total power that took was maybe 30w for 15 seconds. The turbine will be making over 400w of power at these times so we're totally fine to steel a drop or two of power for the sake of safety.
@@HarmonyTurbines
Whut?!
Is motors needed?
Why not a passive centrifugal regulator like old steam engines?
Horizontally-oriented wind turbines have variable-pitch blades, which enables them to adjust appropriately to wind velocity. The major issue is mechanical complexity. Those burning turbines are a result of these systems failing. I guess the greater efficiency of horizontal turbines keeps them worthwhile.
the problem is changing direction of wind. in such case this could be useful.
@@jebise1126 Horizontal turbines can change direction, but the wind doesn't change very rapidly in the environments in which they are constructed. Generally: wide open spaces. It is true, though, that they're not terribly good for small scale generation in more cramped locations, like in cities, where the air might be more turbulent.
@@jebise1126 home scale ones have a tail so they change direction according to wind. they produce 3kw in some models
@Kelly Harbeson They can provide a great deal of power. The problem is that their status as "green" energy is dubious, given that the blades can't be recycled, they have a huge concrete foundation and it takes a lot of petroleum-burning equipment to do all the work.
Recently saw a video about a company that recycles nothing but turbine blades & Solar panels.
Amazing device and fabulous commercial name. Congratulations from Spain!
An idea would be to introduce a centrifugal governor like those on steam engines. That way the system can be analog, not digital.
The governor on a stream or diesel engine works by cutting off the steam or fuel supply.
How exactly is your governor going to throttle back the wind?

@@kamoteph273 hmm. You're going to need some kind of power assist for that don't you think?
@@goodbye8995 centrifugal force rings a bell?
@@goodbye8995 He means a spring working against the centrifugal force. At high wind speeds the centrifugal force keeps the rotor open, at low wind speeds, the spring overpowers it

We can’t wait to see one on Our Property!
Well done! This is a great idea. Good luck bringing it to market. This makes so much more sense than the big bladed turbines we see now.
It really doesn't.
There are major issues with VAWTs, the primary ones being the stress on the lower bearing (think of the leverage), the poor start at low wind speeds (for savonius turbines) and the poor swept area.
No, the mathematics and economics does not add up. They will cost too much and be too inefficient. Do the mathematics and see you will need about 100 of them to power 1 home.
There's a reason why people who build wind turbines to sell the electricity choose 3 bladed horizontal axis types.
@@TerryClarkAccordioncrazy I agree with you - and it is clear from the responses from harmony that large-scale production is not their market. They are looking at the small and medium market, where their VAWT design definitely has some advantages.
@@Alastair510 What advantages would a VAWT have?
The vertical wind turbines are economically and mechanically advantageous to us and the environment and as it is a work of art for I always believed sustainable energy could take over. I wish you all success in your endeavors.
Seems like an interesting solution to the problem. Not an investor (I have no money), but I am an engineering student. Out of curiosity, I have a few questions; answer as you see fit.
How resilient is it to dust and plant fiber getting stuck in the furling mechanism and how often would it need to be cleaned if it were placed in a highly rural environment? If I look at 4:48, the plate that holds the blades to the central axis looks like a particularly vulnerable position to this type of wear/maintenance.
How was the shape of the blades chosen- is it optimal for high-speed wind, low-speed wind, cost of manufacture, or some mix between?
Is the furling system purely mechanical, or does it require a microcontroller to operate it based on a function of rpm; if it is a microcontroller, what wind speed is required to break even on power generation, and how was the furling function developed?
Is the system vulnerable to sudden strong gusts?
Is the system right-to-repair friendly, and if not then why not?
What is the break-even time on energy costs, i.e. how long does it take to pay for itself?
Coffee, dust and plant fiber will need to be tested ...obviously being higher up will help but that's why we go from development into testing so we'll cross that bridge asap. You're comment about wear is over-rated. The amount of time the furling mechanism will operate in a month will likely be just one or two hours total. Mostly it will be for seconds at a time and the rest of the month it's just sitting static, rotating happily. But there are nylon wear (washers) in between places where friction would occur. Shape of blades is a very long story, not going to get into it now. Mechanical microcontroller for furling yes. Sudden gusts are smoothed out by the weight of the system itself acting as a large flywheel and it seems to handle them just fine from early testing. Yes repair friendly. We estimate about a 7 year ROI if you have good strong winds in your area and $0.15 or greater cost per KwH electric.

I’ve always liked the vertical wind turbines but most are set at a fixed blade, scoop or what ever it’s called. However your design with variable settings in relation to wind speed is a great idea.
Thanks!
You bet!
How efficient are these turbines?
I'm guessing they produce quite a bit of drag on the sections that aren't facing the wind...
David, It's finally coming to light that there has been a large disinformation campaign for decades against VAWT's and in general Savonius turbines, starting back in the 1950's or around there. Savonius Turbines are actually > 30% efficient without any helix twist or ribbed sections. A proper helix twist greatly reduces stress over the entire unit and smooths out operation as well. The main noted drawback noted was high wind vulnerabilities which our patented design now solves. Look at this ua-cam.com/video/pbtR6VG-gLw/v-deo.html
As a welding engineer in the 90's I had the chance to work on a energy project
at a steam generated electrical plant, it very similar set up was used to govern the turbine speed, the main difference or improvement was in the impeller, the rear of it was shaped into a rounded tear drop there for reducing the return drag of the impeller, that improvement alone made it 16% more efficient and quieter! Also look into bamboo fibers and resin for making the impellers with a mold they can be made lighter and faster! Thanks Nate

Can the design cope with sudden onset of gusts of wind? Perhaps it could also benefit from being self-governing, that is closing up as wind speed rises even when the control fails to crank the motor.
I would expect that it can't. Gusts will pull the flimsy bones wide open, with how many moving parts it requires to function.
My personal guess is that compliant materials will be the solution these problems are looking for. Not sure how, though.
Super information, I am wishing you to success in this project.
Thank you very much
Found your channel searching for solutions.
I live on a small off grid business property in Doney Park AZ (suburb of Flagstaff). We have serious gusting wind here, nearly 365 days a year. Recently gusts topped 90 mph. Our power needs aren't substantial and our revenues are (currently) humble so cost is an issue.
Do you have any cost projections on full systems (less battery bank)?
In Arizona, use solar.
@@Stefan_Dahn I have solar but have parts & want another alternative for backup.
don't waste your time, this is a scam.
And as of your concern, wind turbine benefit a lot of scale, so for individual installation it's not a very good solution. Would be much better to reach out to local community/authorities and collectively fonds one or more industrial sized one. To minimize battery usage the best solution is to pump water up (PHES) it's especially good if you are in mountain region. But unfortunately AZ is more flatland and not much water to spare i believe, so i'm not sure it will be suitable in your particular case. Big flywheel can be an option but here again scale is your best friend, i'm not sure it would make economical sens for individual installation, although industrial size one do show pretty good abilities. I know in Spain they explore molten salt solar panel and they would be a very good solution in AZ also as the climate is probably pretty close, but once again that only make sens in industrial scale as it rely on thermal mass (energy is stored as a volume so m^3 and lost is per unit of surface so m^2 so the bigger exponentially the better). Although i totally understand the will for independence (and actually share a major part of that desire) i'm afraid energy is one domain where community scale is king. The only interesting individual solution that i can think of (out of solar panel + lithium battery) in your case would be low/mid depth artificial geothermal, but it only cover thermal regulation part of the energy need (i.e. : heating/cooling air) and you need land area at least 10x your house living area. That show very good result in south of France, they install it under olive tree plantations.
Just ask your neighbors. Lots of people in Flagstaff have wind turbines. Otherwise, you can take a trip to the university and ask to see their renewable energy lab behind the engineering building. You can see the whole setup there and two different turbines. If you find a guy in Hawaiian shorts, he’s the one to talk to.

Lots of wind turbines have breaks and blade pitch control to resist high RPMs in severe winds...
Finally, this is great! I hope it's reaction time in extreme weather is 'up to speed'
Could you add a concave cover on the wind catching side? I love the design but here in Maine that scoop is going to fill with ice and snow...and that's the time of year I'm going to need it most in a hybrid system. Perhaps a heating element?
Could probably just remove some of the lip on the bottom to maybe 10% of what it is and still keep some of the original rigidity. It could still flare at the base where the gear teeth are.

@2:24: direction of smoke doesn't seem like there is severe wind... just mentioning
Having a bachelors in electrical engineering it doesn't seem that this produces enough power to power a small house let alone something industrial. There's too much of moving parts where energy is lost. That's what makes the 3-bladed wind turbines way more effective - low amount of moving parts.
I don’t much about this but I looked incredibly inefficient and a lot of places for loss to build up
what moving parts are you referring to?
@@lorenzo42p
02:13 On just 1 of these layers there is 8 points of contact where friction is created. That is the middle gear that touches those 2 half-gears on wings, and then you have poles that are in the center of those wings. Mind this construction is intended to not be fixed because the wind needs to open and close those wings automatically.
(03:12 may be a better visual for this)
03:29 Because this is 4 layers it becomes 32 points of contact where friction is created.
Then the whole construction needs to be held vertically by at least 2 points (1 on the top and 1 on the bottom)
so as a whole there is at minimum 34 points where friction is created and that could drastically add up to major energy losses.
Also the shape of the turbine is inefficient so you already have losses there.

@@PurpleDuneEfa the gears on the wings only move when the wings are folding or unfolding. the wind does change a lot, so that could be often. it would need a motor to turn those gears, which is extra load on its generation. this type of wind turbine is known for having very low efficiency, as it fights against itself as you described. I can see dirt getting pressed into those gears and jamming up the whole thing. the wind tends to pick up and carry dirt, and there's a lot of the stuff out there in nature.
I'm impressed! If you would like to test one in summer temps that can reach more than 115 degrees with occasional very high gusty wind speeds (once reached 115 mph!) , you could put a prototype in my Phoenix, AZ back yard.

I saw something very similar in Florida when I was visiting my dad at an expo. I just assumed it was some sort of public art sculpture.
I enjoyed this video and your concept very much. Thank you for sharing. Question : Do you have any plans in the far future to design a turbine for waterways using your open / close system.??
No plans at this time for a waterways system Maurice. But many people over the years have asked me about it. Yes it would work in water just fine though water does not often flow faster when you have flooding, just more volume so there's not much need for the furling capability in water applications.
I've probably watched 200 wind turbine videos and only today stumbled on this. Brilliant design and aesthetics, I look forward to watching from the beginning
And out of those 200 different wind turbine videos, how many actually came to market and is actually producing decent price per watt power? Many wind power scams have come and gone. Why isn't there any demo of this actually generating any power?
I think you misunderstand. I would never spend a dime on any windmill or invest. I am however happy to "borrow" the design and built my own.
Good work Chris
Can an array of them be mounted on a flat roof ?
How close together can they be before they interfere with each others airflow ?
They can actually interfere in net a positive way. Their next video at 3:14 mentions a paper showing that vertical turbines in a grid pattern improve performance by up to 15% (spaced by at least three turbine lengths)
@@dl5244 Thanks for that
Great invention I think, keep on doing the excellent work, this can save our planet.
Interesting, we need to see the cost though as it's competing with solar, less complicated wind turbines and the grid which you can already buy renewable energy from for a low price.
Our goal is to sell them for 2500 USD shipped globally. We estimate about a 7 year ROI if you have good strong winds in your area and $0.15 or greater cost per KwH electric. We have 120 videos so maybe you should watch a few more. :) Please sign up with our Newsletter to receive the latest updates from Harmony Turbines: groups.google.com/g/harmonyturbines
I suggest you propose this design for boats as well. When the turbine contracts, it can become a Magnus Effect cylindrical rotor. This only occurs when the wind is perpendicular or slightly diagonal from behind. At any other angle it would be open, not for propelling the boat, but for other needs on board.
Thanks we have been engaged with both Yacht and Catamaran manufacturers for about 2 years now looking at this. Once we're further along we will be working on units to do exactly this. We have even had Cruise lines contacting us so Magnus effect and Fletner rotors are definitely on our TO-DO list. :)
This is so cool!! A few questions. Have you thought about using composites for the air scoop to keep weight down and strength up? Also, is the unfurling mechanism electrical? If so are you using a slip ring to deliver power? And lastly can I have a copy of the stl files of your original models I kinda want to test out making a 5v device charger that can be carried around, or used in camping.
Watch the video close enough, warm up your CAD Skills & Start your design, and you'll probably be OK!
A fascinating, simple & elegant iteration on wind turbines!
No matter what you do, Betz's law limits the available energy, making small turbines an uneconomic proposition. This will always be the case.
Furthermore, the image of the burning turbine, supposedly caused by excess wind, is bogus. That fire would be down to failure of the mechanism, itself designed to adjust to wind speed, not the fact that the wind was strong. This silly design would be no less likely to have operating faults.
I love the idea of a self-defense mechanism against extreme winds, best of luck
Reduce the torque the shaft has to deal with by having two sections of buckets spinning in opposite directions. Will reduce the amount of concrete needed in the base.
I'm not sure I understand what you mean. Assuming the wind is coming from the west, the pole will be pushed the opposite way, regardless of the direction of rotation of the bucket sections.
@@londonnight937 Torque.
Significant step forward in the wind energy business. Major improvements:
1. Continous operation during wind storms. Non-interuptable power. Huge advancement.
2. Very little noise and no propeller flicker. Huge step forward.
3. This design is not a bird killer. Very important.
Support these guys, this is the way forward!
Thank you Jim, we're doing our best to push as hard and fast as our time and finances will allow.
I thought that vertical turbines, while they always look cool, have been pretty soundly debunked as having terrible efficiency, particularly compared to blade turbines.
It's all because power is proportional to the active cross sectional area presented to the wind.
It's finally coming to light that there has been a large disinformation campaign for decades against VAWT's and in general Savonius turbines, starting back in the 1950's or around there. Savonius Turbines are actually > 30% efficient without any helix twist or ribbed sections. A proper helix twist greatly reduces stress over the entire unit and smooths out operation as well.

@@HarmonyTurbines But... physics?
Looking at that prototype only 25-30% of cross-section is even capable of catching the wind, and a lot of the other side are actively opposing it. Now, maybe there are rotational components I'm not considering... does the pictured prototype ACTUALLY generate 400w of power? Under what wind conditions? If so that's hard to argue with.
@@HarmonyTurbines ok so now you claim that 50years of scientific literature is "disinformation campaign" ? And that for promoting a win turbine design that is not even your's ? Patented you say ? BS ! I call you patented liar.
If you want to call out on scientific result it's simple set up an impartial protocole and put your numbers on the table.
This is the first I have heard of this design!!! Why?
Has UA-cam been blocking your content? I wouldn't be surprised.
A savonius rotor made from an oil drum will typically produce a bout 180 Watts at a wind speed of 10m/sec (Wikipedia). So your design is barely different so it won't produce much electricity: something you conveniently didn't mention. If you've spent 3 years so far then you haven't got very far. Sorry but you are backing the wrong horse with this project.
Persons living in mud huts do not have extravagant requirements for electricity.
My understanding is that your comparison Sir, is not suitable to make solid point. The new type of blades are far more sofisticated than the Mother Earth type possibly could have been. Fair enough though, it was your opinion and not based on facts.
Love how many people are trying new energy options! This is great!! A guy from Japan, Atsushi Shimizu designed a turbine that will withstand hurricane winds and produce power.
Challenergy claims 30% efficiency, where a conventional horizontal turbine gets 40%. Vertical axis turbines have a severe problem. The reward-facing blades fight the foward blades, greatly reducing efficiency. I seriously doubt their 30% claim. I used to be president of a wind turbine company, so I know all the calculations. Unless you have some moveable components, you are simply not going to get that much efficiency out of a vertical axis turbine. Once you add complexity, you add cost and reduce reliability. You might as well go to horizontal axis and gain much higher power. Farms have been using horizontal axis for many decades to pump water. They are simple, reliable, and survive the storms you find on the plains.
I'm not interested in video footage of work in progress or fluff about saving the planet for a better future for the kids, I want to see HARD DATA, ideally in the form of a graph of Power Generated VS Windspeed. This is the bottom line. Thanks.
That will be coming as our 3 universities (Bucknell, PSU & Northumbria) begin their research projects on Harmony and our technology. Performance data and lots of other great stats will be fully published then.
@@HarmonyTurbines So in all the years you've been developing, you've never taken any basic power measurements and correlated them against wind speed? Not even a Prony brake style set up to measure raw mechanical power from the turbine shaft? If not, how did you become convinced you had a worthwhile product on your hands...? 🤔
@@saiello2061 the pony brakes that we looked at trying are thousands of dollars and need stationary mounting. This means we have to have wind come to us which is unlikely in our area with such bad winds here. To mount a setup on a moving trailer or platform is also very complex and dangerous as we found. If you have links to a simple inexpensive pony break, I'm all ears. We also tried 2x different off-the-shelf generators and both were terrible for our low RPM’S. So what sounds like a simple thing is really very complex. It's why we're now developing our patented generator. It's our best option for moving forward and getting all the data we want.
@@HarmonyTurbines Sounds like excuses to me now. You can make a Prony brake for next to nothing using some form of spring balance, a handheld tachometer and a few other bits and bobs. Lots of info online. As for a generator, there are so many options out there to get some sort of voltage/current reading it's hardly worth mentioning. With the size turbine you're experimenting with, I doubt you'll even be getting 100W shaft power out of it in a stiff breeze....
@@saiello2061 you be as angry and pissed off as you want. Scream at the top of your lungs and run around like a little girl. It doesn't matter what you're saying "should" be easy or quick to do ...it's not. We've had PSU and Bucknell both look at this issue with us and it's more complex than it appears at first glance. The way other turbine companies get their power ratings is NOT with a pony brake. It's with a properly sized generator matched (tuned) to the RPM's that they need to run in a wind tunnel at the rated windspeed. Then most of those ratings are thrown OUT the window because Underwiring Laboratories demands open air equivalent testing which negates wind tunnel testing and wall effect from compression. But who am I to tell you ...you seem like an expert and probably know all of this. For now the best I can give you is a "sorry you're going to have to wait" the data is coming as quickly as we can get it. No amount of insults from you or anyone will make them come quicker. By the way with the CRAPPY generator and charge controller we had we got up over 300w in our testing last year so your 100w prediction is off by a factor of 3x.
I love inventors like this
Inherently inefficient, especially near the ground. Some aerogenerators break down, so do all machines.
Your success is everyone's success.
I am so glad you are out there trying. I wish you could publish the actual data on how much electricity your system can produce versus the conventional propeller/airfoil design. All large scale industrial wind farms are sticking with the airfoil design; they must have a good reason for that. I have read many explanations on why they use only 3 skinny blades, for some crazy reason I am not convinced, we need more blades and fatter ones.
That's a beautiful design! It looks like a life form.
Thank you Old Man. I believe it could be the new global standard in small scale wind power generation. We just have to get through the rest of our development and move into low volume production.

@@HarmonyTurbines I think that the aesthetic appeal of your product should not be forgotten in your efforts to promote.
When you were having videos shot for promotional purposes, I think it would help a lot if you had an artist involved in the presentation.
I am not suggesting that it should be me, frankly I'm not qualified. I'm just sharing my perspective because your product is inspiring.
@@theobserver9131 Thank you... I have spoken about this in many of my videos. Perhaps having different color options or allowing people to have custom silk-screen prints on their turbines. It would be more expensive but very cool. Flames licking upwards, for example. But yes the Aesthetics are one of Harmony's biggest selling points and that includes their being SILENT in operation which is also hugely pleasing to onlookers.

What is really cool is that this would fit at my house! I am in a very windy area in South Africa.
Awesome build brother! I will definitely tell people about this
Wow love it! Someday will get in touch with you. Wishing you all the best from Sri Lanka.
This a great invention, as industrial engineer to be am proud of your work. Working with wind turbines companies to produce green energy is always my dream
Put a series of VAWTs on top of existing Electric Power Transmission Line towers, so that most of the height above ground is built, and electrical connection is mostly built, and right-of-way maintenance is already planned for and budgeted. It could also be done bit by bit instead of having to be mostly complete before being useful. At least, when building any new or replacement towers, take into consideration building them so that VAWTs can be added later.
You should look into adding lightweight extensions that slide out from the "blades" for even more power.
Superb video and concept. Well done! Keep pushing
I like what you've done with your truck
Excellent idea added to an old idea ... BRILLIANT!!!
Praying for your success.

As if praying is going to change the laws of the universe. Power is mainly determined by wind speed. For 1 square meter the MAXIMUM energy from the wind is kW = 0.0006 * wind speed CUBED. So for 1m^2 and average city wind speed of 2m/s you get 4.8 watts. Small city wind turbines will always be useless.
Would be interested in one for our Off-Grid Homestead.
The yin yang shape is very pleasing also!
To power a home in an average city (wind speed about 2m/s) you are going to need about 120m^2 of surface area to be covered with these turbines (that should give about 500 watts) (more like 360m^2 at 30% efficiency ). The problem in cities is the low wind speed. Big turbines are built in high wind areas and are tall to access the stronger wind. The formula for the maximum wind energy from 1 square meter is: kW = 0.0006 * *wind speed CUBED* So for wind at 2m/s, and turbine area of 1m^2 you have 0.0006 * 2^3 = 0.0048 kW (4.8 watts). But efficiency will probably be about 10-20% for that design. Turbines always face the mathematical physics of *wind speed CUBED* you solve that by finding high wind speeds (tall turbines mounted on ranges, or where there is clear air out at sea).
Sabert00th if you have 2m/s winds at your home you would be denied approval for a Harmony Turbine. Sorry to break it to you. Coastal and boating customers will be our first target market. Extremely good winds with high incidents of storms and severe wind events. Perfect for our products.
@@HarmonyTurbines sure, but for the majority of the population these will not be effective.
@@HarmonyTurbines "denied approval for a Harmony Turbine", you are that important?
That is remarkable 🙋🏼♀️ I hope it catches on quickly.

I’d think you’d want to try and utilize the storms winds.
Yes, that's exactly why I created Harmony, to capture all the amazing wind that others are ignoring.
Wow this is ingenious. Wish you all the best
Very interesting , I am from Puerto Rico where the weather is constantly changing and huracanes are a constant weather challenge. There is a critical energy situation in the Island and I think this type of Turbine could be tested there.
Great idea 💡
Very cool. Great advancements on a brilliant idea👍💕
I have always loved the Savonius design. Very cool spin you have put on them.
