- The most powerful vertical axis windturbine (VAWT) on earth?
Of course !!! IT IS NOT !! ...is it forbidden to have some sense of humor ?? the RS is an amazing wind accelerator.
That means: the RS doubles the windspeed... and that is: power x 8 !!!
(Newton's second law of motion: If the wind speed is twice as high, it contains 8 times as much energy )
If the sweptarea (booster flaps) is made larger and larger, it is even possible to triple or quadruple the windspeed !! (with very low investment= super ecological footprint= Good ROI "return on investment")
That means:
RS SUPERBOOSTER produces energy at ULTRA LOW windspeed
That means : the RS is suitable for areas with too low average windspeed for conventional wind turbines (Darrieus)
As we all know: It is pointless to install wind turbines in areas where the average wind speed is less than 5 m / sec
That means : The RS is suitable in areas with even only 3 m/sec !!! (or even less)average windspeed.(more than 80% "on shore" average windspeeds on earth have less than 5 m/sec)
NOTE : GreenEnergyFoundation is a NON PROFIT organisation !!
All "royalties" are 100% invested in Third World countries(100%donated).
I didn't think much of this wind boosting tech until after seeing this video. Very impressive, thanks for posting this.
This is a very simple device to build. I built an 8 sided one. More importantly it's a great educational project.
When I made mine a few years back I sent it's design to a few colleges.
Sadly they said it cost to much and had to much swept area.
I work in a metal factory. I can make most the components from our scrap. And package it by upcycling our corrugated board.
I could also suggests to keep the packaging for additional projects.
Look at the 6 yellow fins. Sandwich them between plywood. That's how I did mine. 8 fins though.
Now put that device on a hill. The hill also funnels the air.
Use solar panels with it for same effect. The device now become a mount as well.
Roofs give the funnel effect as well.
Since it's easy enough to build with many different materials makes this ideal for 3rd world countries.
Just my thoughts.
Maybe someday I'll be able to talk my boss in to making these DIY kits from our scraps. But not yet.
Great idea. Great educational project.
Успехов тебе!
How fast it's spinning is of no real interest. The important thing is how much energy can be extracted from the flow. What needs to be measured is Watts, not R.P.M.
good point!
That is correct. The implication left, otherwise, violates both natural sense, and natural laws of physics.
In certain condition, the faster it spin, the more energy inertia it hold and manage to overcome power losses due to frictions when attached to the generator. Thus, more watts output generated.
@@tanpabaju2556 no sense, to justificate the friccion, the value of the fricction would be in comparation of more inerce at some times not valace. sorry but not convinced.
Doesn't the deflectors merely increase the surface area of wind that is directed over the blades? Someone mentioned the pressure that builds up in front of the blade. It would be good to have an explanation of that. What goes in must come out, In terms of "volume" of water, air, gas, all hit the restriction of the blades right. The blades can only catch so much air, unless this is supposed to be some type of airfoil, which he did not demonstrate the shape of his VAWT blades? Then the issue of high pressure zone and low pressure makes sense. It seems that the deflectors would increase the pressure ahead of the blades which would not increase the power or lift, it would decrease, but once the attack angle was accurate to the deflectors at that moment it would work but counter acted by the other forces working against the blade in front and in back of the one at the optimal angle for the wind speed and shape of the wing?
A voiceover explanation extolling the virtues of the system would have been useful.
good idea
thanks
also what is avp.that would explain a lot!
its like a flux capacitor only completely different.......
Kent Simon Bwahahaha
it could use more banana peel and empty beer cans for increase output
Adding funnel essentially increase swept area of the turbine system. So it's no surprise it increases output.
Yes, but the neat thing is achieving increased rpm without increasing mass rotated!
@@vloogle4924 great point. It would be interesting to have a meaningful comparison with another vawt that's has the same swept area, see which one has higher power output.
Static diffuser(s) try a variation of foil shaped blades, create a negative high speed pressure between the static blades and a positive pressure and dense airflow aft as it acts on the impeller blades. Id like to see if this design would benefit from the aviation tech.
the hard drive in my computer spins at 10 000 rpm , but it wont produce a lot of energy.
These data imply the outer fins are as an important part of a VAWT as its vertical orientation. I won't deploy one without them. Further, the housing will provide a fixed structure to attach the windings for a generator, and heavy magnets affixed to the inner spindle carriage will act as a flywheel.
is there a video to explain this video??
it seems there is----the answer is blowing in the wind
I'll some it up... they recreated a darrius turbine.. (very old design) put a but of fins to dirrect air into it... then failed hard by creating this video and claiming its the most powerfull.. when science already tells you a lenz 2 design is more effecient lol.... my lenz 2 puts out around 550 watt at that speed, its 3 and 1/2 feet wide and 4 feet tall..
with 3.... only 3 wings.. (lenz 2 's wings are position to which the wind push's it and the wing pulls it the rest of the way) push/pull instead of just push like this darrius
here you have one
th-cam.com/video/cYh7jR4vLQg/w-d-xo.html
A couple of points .....
I assume you are simply trying to measure the increase given by your add on to an existing device. Placing it in a wind tunnel will not show this accurately for several reasons
1 You get pressure build up ahead of the device in the tunnel because of the drag coeficient of the device ..... increasing the wind-speed will only amplify this error!
2 You have no load on the turbine so the increase of rotation is, at best academic!
Why not mount the device in free airflow and measure the wind-speed and rotation of the turbine (with fixed load on it) then once you have the measurements over a reasonable range of speeds simply repeat with your add-on bolted to it? That way you get a concrete measurement of Power Increase ..... which I assume is the purpose of the experiment!
I was just about to said the same thing well said they have to show the reality thanks
What power does it produce! My son's bicycle wheel spins in the wind! I can see the device works, but what torque can it handle? How many watts can it produce in given wind and motor conditions?
You might be able to use those flaps to close in dangerously high winds.
Better to make large diameter axis turbine support like 3 to 10 meter dia. and to have the blades articulate to the wind. In such configurations you can take advantage of the airfoil effect of blades/sails. This will vastly increase the torque of the system. It can thus use low wind speeds and It can also be made to self brake or slow down in high winds. Especially useful in rural areas where space is of little concern.
Pretty interesting. Inlet guide vanes. A very simple, but very effective idea.
Anthony Smith yes it does.
Isn't torque measured by the wind speed and rate of air volume over surface area minus co-efficiencies? These blades appear to be very narrow. By the way, the 80's just called. They want their music back.
USNVA “Blowin’ in the Wind” (Bob Dylan) is from the sixties.
The RPM is nice , but what is the power out ? ?
Free spin is easy to make but we are looking for POWER :-o
Great, nice. Lo mas importante es que con muy poco viento ya esta produciendo y el otro cuando apenas empieza es casi triplicado y después se mantiene al doble.
OK, that is amazing no matter how critical you are about the accompanying music, I mean really now, they went to a lot of effort to show these results, I like it! please when you guys get a moment lets see some power being generated from this turbine, be really interested in seeing those results too
Good for you riebedebie, We are running 2 x 3kw vertical turbines 2.5mdiam x 5 x 2.6m blades. While they turn well,start up 2.5 m/s there is no real power with our permanent magnet generators until we have 8 m/s wind speed which equals about 80 rpm. Doubling that with your set up would be very handy. Not practical for us though, our towers are 13 metres high.
collo1712, I'm not sure I understand your numbers. Each turbine has a diameter (not radius) of 2.5m, ~8ft, and each blade of the turbine measures 5m by 2.6m? So each blade is as wide as the entire turbine? Is there any website where I can see these turbines? What percentage of the time are they generating power?
Instead of straight inlets how about slightly curved one?
How about losing the stupid music and adding an informative narrative?
I thought the music was nice. But, yea, how about some narrative?
That was Bob Dylan you fucking moron. He's a legend and you're just a stupid piece of shit. BTW: You're last name has too many syllables.
Green Genes at least I'm not afraid to use my name. So sorry you have trouble with 4 syllable words. That must make you feel bad. I don't have to hide behind a nom de guerre so that I can hurl vulgar epithets at people like a coward. If the point of the video was to highlight Bob Dylan's music it might have been appropriate, but the creator titled it so that one would expect info about a VAWT. Other than a few useless images there was no info in this video.
All of a sudden? You don't know me. You come across a post I made over half a year ago and attack me with vulgarity and you seem to think that's fine. You must have a hard time finding friends if that's an indication of your personality.
I hope you do some chores once in a while to compensate your mom for letting you live in her basement.
You are wasting your time and "breath". What surprised me about this exchange are two things: 1) Little Bobbie Dylan's music is popular with someone on the mother ship, and 2) they allow nuts in the asylum to access the net.Okay spaceman, go ahead, say something inane and vulgar-put your double digit IQ in overdrive.
Great video!!!! Sorry that you did not put some specific load on the shaft. The RPM speaks nothing more about work since bearings friction is too small to measure the difference of work between device with RS and without it. It similar like many here are showing voltages of generator which speaks nothing about work / energy of the device. Nevertheless the sum of frictions and air resistances on the device show us clearly that your assumes are correct and very useful! Thank you very much for this video. ( I partially agree with Rich that many of youtubers destroy their videos by stupid music or with high volume of whatever music. Most of them even use high volume music or even worse disturbing heavy metal or any other music using distorted guitar effects having very negative overall impression of any good video. Any film producer would tell us that quality of noise makes the great film or video and not the moving pictures.)
Please define AVP - - if not by writing it out in the video, AT LEAST define it in the written section below. Definition of RS also possibly helpful
Alien Vs Predator (AVP)
This is a wind accelerating arrangement (set of vanes). The turbine is out of scope.
The idea is to make any turbine spin at low wind.
uh, no, the wind being redirrect on any plane = it slows it down. the only way you can accelerate wind... put a fan on it and blow the air into the turbine... hardly affective.. but hey these guys are frauds anyway, thats a Darrius design turbine, and its not the most effecient design in the first place. a LENZ 2 design will take the same ammount of wind and do twice the work, giving its a push/pull design with actual Y section airfoils :-\
Wrong... Turning at low windspeed is useless. Low windspeeds have almost no energie.
Looks nice and it spins fast.
What form of alternator/generator do you plan to use?
I love this design. I have been working with it for 12 years now. Tinkering mostly with the turbine and working on the alternator for this design turbine.
Achieving max velocity with blade angle adjusting Took a while for me without the wind tunnel.
I took mine to Ocean Shores WA. and tested it on the beach in 30-60 MPH wind storm. Max I could get to spin was 75 mph with out the alternator, free spin. Strapped it to the top of my truck, hooked it to a 12 volt battery and drove back to Seattle, average speed 60 mph. 80-85 mph is max speed I could get it to reach. The volume capacity of my inner turbine area limits air flow and prevents over speed. Truck @ 90 Mph, turbine 85 mph.
Can't wait to see what hits the market, if it does.
are u using a similar design? and whats wrong with 30 mph or more? how are u driving ur alternator? perhaps u need some reduction gears? is ur alternator and load too big for the wind turbine u made?
Yes, it was part of an alternator design patent I was given to build. The turbine itself was was easy enough for me to duplicate.
The alternator design in the patent is my main focus now. Reducing a 4' disk to 9 inches took a little work to complete.
The original PM alternator was to big and sits on a shelf now.
Nothing wrong with 30 MPH unless your pulling tarps over hoop houses in the wind.
When I started working on this, the patents were the only place I could find information on this particular VAWT design. Now there every where in many different variations, like yours.
Sines I'm a relative honest guy, I will let you know this, of all the VAWT's I have watched develop over the years, I like your design the most, for its simplicity.
Same 4 photos over and over again. I drew out this idea about 10 years ago. They are missing several components from my original design that allows the turbine to use the "wave" aspect of the air flow as well as the sustained straight force air flow. The speed of the turbine and the power output are connected, however, this design does not work well with intermittent slow rolling wind. As I stated before other aspects to the design need to be added to get the best power output. Here's a tip for the designers of this turbine: Wind temperature, altitude of turbine and spot barometric pressure all play a part in overall efficiency of this particular device.
Essentially you are increasing the size of the turbine. If you simply increase the size of the internal vawt to the size with the deflectors it will be about the same. It is the same with hawt turbines that use an outer cone to funnel wind into the blades. It is the same as just making the blades bigger.
But the cone is cheaper to make than the blades. Problem is the cone is fixed and in high winds will be blown down where the spinning blades can survive better.
Bonjours !
Je suis Tony, je vous contacte de France et aimerait entrer en contacte avec vous, mais apparemment votre vidéo sur l'éolienne a ses commentaires qui ont étaient désactivé, et soit vous avez mal écrit le lien pour vous contacter, soit vous vous faite saboter vos vidéos et plus...
Vous êtes en Belgique et je vais essayer de vous trouver...
Merci de continuer et de nous donner des nouvelles et de l'espoir !!!
Why no torque figures? High RPM with SFA torque is about as useful as tits on a bull.
for years ive been thinking how to reduce the wind on the other side of VAWT. a lot of concept. but this is not what i think. Good job.
Your results are based on a closed system where the air cannot move around the construction. This means that the air is pressed through the turbine. Under environmental conditions with an open system you will receive a completely different result. The use of guiding plates in combination with a vertical axis turbine is not really new and was already investigated. A power inrcease up to 70 % depending on rotor type could be shown.
We don't think we "claim" something REALLY new !
All is based on Bernoulli/Venturi effects and ancient Persian windmills (3000 years old)
We claim OPTIMASATION of the system
(Newton's second law of motion: If the wind speed is twice as high, it contains 8 times as much energy )
That was our goal...and we succeeded !!!!
the RS doubles the windspeed...and that is: power x 8 !!!......as simly as that!
De results in "open air" (more low pressure behind the turbine) are even better than in the wind tunnel (more vacuum = better exhaust = more power)
The rotor is our famous SuperBooster Rotor (lift/drag TSR 1.2)
I think I am going to build a house inside a wind turbine. The energy is mine...all mine! And the vertigo!
Matthew Rhett Larson. I recommend a yurt since they are round like the turbine. :-)
HAPPY TO SEE THE RESULTS TAKEN CORRECTLY I DID NOTICE THAT AFTER 4 M PER SECOND SPEED RATIO CHANGES DRAMATICALLY VERY INFORMATIVE
I'VE BEEN THINKING THAT SMALL DIAMETER AND HIGH SPEED IS POSSIBLY THE ANSWER THERE IS NO LIMIT ON TORQUE JUST GO VERTICAL. THANK YOU FOR POSTING YOUR TEST HOPE TO SEE MORE
PS I WISH I HAD A WIND TUNNEL TO PLAY WITH LUCKY YOU LOL!!!
Oops! I forgot! Thank You for the great video and information. I think I have to investigate this AVP. Again Thank You.
It's good to see people are doing proper tests on this stuff.
Those who are working on the VAWT alternative are doing something that potentially could move wind power into the next generation and could help climate action to move beyond HAWT. I hope that the SDG network (Sustainable Development Goals Network) supporters in #SDG7 and #SDG9 are able to do something to bring VAWT into the world's action plan soon.
could you tell more about this
Add a load of some kind. High RPM in low wind is easy if no torque is required to spin a generator or PMA.
would stop any of them dead.. you dont put a load on windmills, you charge a battery and draw of that,
simple rectifier makes sure you not pulling from the turbine
can i please have a stl for your model? i find your research awesome!
Power is decided by the generator/alternator. As the wind turbine increases it's rpm, the generator will increase it's output.
Vertical axis windturbine achieves less than 50% of the regular propeller type that we normally see with 3 blades. It is heavier to build. That is the reason why we see more those 3 blade propeller windturbine.
The way the collection vanes are positioned you would think the turbine would spin clockwise. Are the wind turbine scoops, the round part on the left or on the right? The round part must be on the right side for it to turn counterclockwise.
Noise. Any obstacle especially multiple obstacles combined with multiple blades causes a whirring sound. If at all, they need to be of uneven pairing and varying distances.
so, what do we learn: a big screwdriver can rest on the floor of a wind tunnel measurement section safely within the boundary layer at speeds up to 10m/s before it flies away to do damage and gets noticed by the cameraman
I design similar one wich has only 1 and much bigger "AVP" what u can turn always to wind direction. So you concentrate wind speed.
When can I see the final results??
At the end of the video
🙄😅
resuming, you get 60% more energy with the system than without it. and also energy with low speed. Great! thank you! good job!
Actualy you can harvest wind anergy at larj ariya with tha dayrection partition, obvesly you can gat hi speed,
If you can test with sam window ariya for both model then test result we need,
Double the apparent frontal area of the turbine doubles the power collection. That's what should be expected, right?
I agree, larger fins to collect more wind = more torque then gear it up for more rpm at the generator. I do see some benefit using larger fins to channel the wind, like being able to keep the spinning moving parts smaller. also maybe channeling could increase wind speed like a venturi .
It's blocking the wind from te ruturning direction from the blades (the ineficiensy of vertical axis wind turbines) and jost that will speed up the rpm 1,5 to 2x (so boosting ???) but it work good blocking the wind from any direction with no need for moving parts (eg a teal moving the blocking part) so good.
Hi we are in a 3rd world country (State of Para, in the Amazon, Brazil)... Can you help us design small windturbines 5kw/10 kw so we can build it here so small communities that strugle with power shortages can have better life ?
I think I may be able to help ...im working on the same type of issue and came up with some amazing outcomes...
How can I contact you ?
My email or phone 646 946 3574
Or 1lawharris@gmail.com
I'm in an eastern time zone
I put it on mute so I could understand the video better. There are several principles of physics that can affect how the system functions and what effect the wind has on the mechanism.
hi, sir, i work on the same project please can u send to me the information about who to build this VAWT
excellent idea to be tested in practice.
I need just 4250 KW / years for my consommation of electricity
The old wind mill from decades ago used to develop lots of energy with its four massive sales which was realy needed to operate the heavy machinery ,by using ones imagination how much electricity woud it turn out if it the same machine could be made under modern techniques
Why isn't this with the avp technology up and running instead of the normal unefficent turbines that are up today?
Your project is excellent, I hope everything goes well!
Did you realize this project in full size (with the wap)?
do you expect you to send me documentation (pdf, dwg,…)?
Thank you
Good luck !
RPM != Power
cP & torque are powerindicators!! but are tied to rpm (double winspeed= 8x power & this turbine has double windspeed !!!)
I'm not sure the windspeed ^3 rule would apply in this case because as the turbine resists turning (when it has an alt) that resistance may have a larger affect on the incoming wind. I do think you will get close to the power of the area of the collector instead of just the turbine though so it does help.

The wind moves around houses and other structures but your design acts like a system of sails and to cope with strong gusts of turbulent wind you would need a very strong support system (set in deep concrete.) Here in Southern Alberta Canada where we make a lot of wind power the winds gust a lot( 35 mph to 55mph in a heart beat). I've witnessed roofs blow off, 90 mph gusts. Empty panel trucks were blown over. If you have the guts to want a real world test, bring it here and get permission to bolt it to the 3 Rivers Dam test site outside Pincher Creek.
By the way, you can play any music you want but ACDC would be great to listen to while you're watching the destruction.
You wish... I would love those winds. :0)
You could put a high-torque gear and have the whole device spin in case of high winds.
Less music and more natural voice naration (no synthetic computer voice) would be nice. What does 'RS' stand for? Good to see you corrected some of the spelling sinse your last video. Correction, "Asymmetric Vortex Propulsion". Close, but no cigar.
Good luck in holding any Interlectual Propery or receiving any royalties, as 'Variable Guide Vanes', their correct name, have been used in Turbine Engines and Exhast Driven Turbine Supercharges (Turbos) for decades. Nice try though.
So much wrong in this video, the major one being no load test.
Converting the wind booster baffles into 3-D Venturi Effect wound dramatically boost the power output also. In other words extend the baffles above and below the 2-D plane of the wind turbine blades. This will increase the surface area of wind captured and introduce the Venturi Effect (curved baffle profile above and below the plane).
Additionally the wind baffle structure can incorporate wind brake safety features, like to close baffles when wind gets too strong & screens to prevent animal strikes.
Can you do power output tests?
If it's not connected to a load it's not much of a test. Connect it to batteries and charge up the batteries.
The problem is, if you simply increased the diameter of the rotor to equal the diameter of the vanes, would you get even higher efficiency and with far greater simplicity and easier installation . It's the same issue as Ducted Horizontal Wind Turbines.
If you increased the diameter of the blade to that of the diameter of the duct, then any supposed 'gains' are (pardon the pun) blown away. No such thing as free lunch.
Your not compleetly right here...
In TH-cam we have one video (have feeling from Israel??) were one guy show own vertical turbine with "guiding plates" and tell, that he have a patent over that system. When that pricip is too long known, is it possible, that we cant use them for economical profit!?
The Japanese are working on something like this as well for the 3 blade type (sorry don't know a lot about wind turbine). It looks like the same principle... This is great!
with NO yellow vents it gets wind from the whole of the windward side, with the yellow vents it gets wind only from 45% of the windward side
so the yellow vent is acting as a channel compressing the wind
Anything can whizz round POWER OUTPUT
RPM doesn't matter. all matters is how much torque
Imagine a little DC motor as a test load generating milliwatts, and see if you can significantly increase the output. Otherwise, it's a gadget.
I like the "stupid music" an informed narrative is only needed for simple minds.
A little more information would be helpful, as it stands it is just an irritating teaser.
g
do you have plans I'd love to make one. My average wind speed is little above 4 m/s
Very efficient but does it have control in different wind conditions to prevent fast tear down in bad weather
Spinning free with no load what does that prove?
you cant put a load on a wind turbine..
all you can do is charge batteries... then dump the batteries, any load on the turbine will stop it dead..
and yeah, even those gigantic ones.
@@harleyme3163 - You can sure as hell put a dummy load on the output of the generator. Otherwise, everything is meaningless. It's the difference between a dynamometer and a tachometer.
@@harleyme3163 Idiot.
Super, j'ai fabriquer une colonne double à 9 pâles de 440 sur 800, qui tourne à 120 rpm, bois et PVC, je vais fabriquer votre amplificateur c'est pas con, merci
espectacular rendimiento los felicito Dios los bendiga
Small and light weight horizontal wind turbine can we fix on electric car for charging while driving ??
good vid, also GREAT SONG, it Scorpions song about world peace They were the first band from out side the USSR to be let in after the fall of commy control. Watch Winds of Change by Scorpions, its a awesome vid.
Thanks for the info.
Yaarrr.... Where is the Torque? Only RPM isnt enough. Good Concept by the way
so basically attach a funnel to catch more wind, ground breaking lol
was there a generator attached ? was there any load? looks good
could you help us to produce such kind of turbine ..could you tell the information of generator?
How can we have it? Need solution for a project in Haiti. This fits perfectly!
And just how big, expensive (and ugly) does this have to be to withstand a gale without the whole caboodle disappearing over the horizon?
do they not have a website, is it so difficult to paste the link of the website of greenEnergyFoundation.
Why in the world would anyone want more than 300 RPMs for a wind turbine. The most recent system that I designed generates great power at 200 RPMs. Also, I am not an engineer to begin with.
cwrobinson6363 i suppose you could put a transmission gear on it and run your generator with more torque
Nobody wants more than 200/400 RPMs but for a TSR 0.8/9 turbine (Savonius) of more than 3 meter diameter is that impossible to reach without gears !!
All low RPM PMGs need only 200/400 RPM max. and the RS is THE solution for that problem
Terminology question: RS?
Sorry, another terminology question: TSR 0.8/9 turbine?
What interests me is the final power output ??????
would like to see a model were you take 5KW out, how big it needs to be?
diam 8 m x heiht 2.5 m
show us one in real en give all the specs, also how much noise it produces can it give 5Kw @ windforce 3 we are looking for the real stuff not maybes not only @ top windspeed.
a 2 kWh proto is in production
as soon as we have results we will publish them on youtube
24 feet in diameter!!! Does that represent the outer measurement of the shroud, or the diameter of the turbine itself?I assume your estimate took into account the torque and rpms necessary to drive a 5 kW generator, as well as the gearing necessary to raise the turbine shaft speed to required generator shaft speed?Also, does the configuration shown in the video represent the most effective configuration (angle of the shroud walls, angle of the turbine blades, width of the turbine blades, etc?)Why does the turbine on the AVP system seem to turn in the opposite direction as the non-AVP turbine?One more thing, is it possible to shape the AVP walls to produce a venturi effect aimed at the outermost part of the turbine blades?Finally, excellent video. I also liked the music, found it humorous. I thought the video was just fine without narration, better really. All the information you wanted to show, I could see. Narration would have been a distracting noise to me..
what ever happened to this project and where can one contact the people behind it
Ótimos ensaios amigo ajuda bastante.
Do you sell a kit or plans
FANTASTIC !!
Does adding the vanes increase torque as well as velocity?
YES and NO : but best way to know is : see Bernoulli & Venturi effects on internet
you need to show some verifiable data that will be used to compute for power, because any increase in RPM alone is not sufficient to confirm your claim. Please include the span, chord and the coefficient of lift and if possible what NACA number was used in your airfoil if it is an airfoil, the pervading temperature when the test was made and the elevation of the test area whether above or below sea level, what was the angle of attack?
This is a Drag turbine i think, so it does not have Cl.
yes, I think is something like a turbo, drag based windtubines as far as I know are always less efficient than lift based so..the title of the video is already false :), but nice turbine anyway
You can probably stop this turbine with your finger. It has very little power output potential.
It doesn't matter how serious or technical the video is, IT MUST HAVE MUSIC! HAHAHAH where are the naked dancing girls?
Funny... I've seen six videos lately of different wind generators that say "The Most Powerful...."
