Tunisia: Revolutionary bladeless wind turbine could change game in wind farms
Вставка
- Опубліковано 11 жов 2024
- Tunisian innovators have looked to the past for inspiration from sails on ships to come up with designs for new bladeless turbines.
A start-up known as Saphon Energy has developed a new turbine design which is quieter, safer and more efficient than traditional wind turbines and is capable of capturing twice as much wind energy.
37-year-old engineer Anis Aouini leads the Tunis-based firm. He says that they looked to the old technology used by sailors of the ancient civilisation of Carthage, as…

In case it's not obvious to you, it can only potentially extract the energy from that tiny circle of wind, that's why turbines have big blades, to interact with a lot more wind.
For all people that can only speak
Try to provide advice in a polite manner. This is an important achievement for Tunisia. The creative mind behind this invention has proven its worth, so please stop your mockery
Well, I'm not trying to offend anybody, but I'm pretty sure that it is impossible for that generator to have an 80% efficiency (as they say in the video). The maximun theoretical efficiency is Betz limit = 16/27 = 59%.
all you people commenting got it wrong, this is a wind GENERATING machine. It generates wind. In other words, it is a fan.
This looks like a very powerful system. Good enough to power a single LED or 30 mA..... On a windy day.
A wind turbine’s efficiency can be imagined pretty easily by thinking about what would happen if you ran the turbine generator as a motor. Would this turbine turned into a motor generate a lot of wind? I think not.
wow, I had seen a many bad designs, but this is an ultimate winner :-) The wind turbine power output depends from the crossection area and the windspeed. It looks, that the Tunisian engineers need a little bit more study of technologies 50+ years old.
I wants to see a scale up of this technology i.e. a 20 feet size dish flapping in a hail storm? yes, yes, do it!!!
I have to add.. the cost of the gearing that produces that oscillation, and is out in the weather... Big money sink. Also, that gearing is spinning mass - a big energy sink. Add in the (relatively) tiny surface area for wind to act on, and I don't see how this could possibly be more efficient than a spinning blade.
It Will Never Break
Its So Well Balanced
Wow, they are really close! All they need are some large blades and then redesign it to make it rotate centrally instead of the power losing eccentric position...lol!
To all you skeptics out there. The engine works and had lots of prizes all over the world where it has been presented. Microsoft is even in talks with the company in order to become a global distributor. Yes it is African, but it will be wrong to presume that there are less competent inventors in Africa. Half of the engineers in Nasa if not more are from so called developing countries. This company just chose to produce this turbine in Tunisia. It's going to be manufactured very soon in large scale. I suggest that you read some more about it, litteraure it's available in the company's website and various other places. The Saphon is going to be installed in India pretty soon. Many countries in Africa in Asia are interested in the project. Good luck to one innovative energy provider with zero pollution
Peder skram what we cant critique stupid ideas because they come from 3rd world countries ? Are there ideas held to different standards? Your being condescending assuming anyone believes this is stupid because Africa came up with it. It's stupid because there is very little energy in air. 1/4[1.225]A*V^3 to be exact. So fundamentally to get more power than the big offshore turbines it has to be about that same size. Can you imagine a 190 m diamater dish!? Preposterous wind turbines work by using as little material (blades ) to sweep the largest area possible ( a big circle) this only gets energy from air that runs into it meaning you gotta build the maximum amount of material for minimum benefit. Fundamental laws of physics say this not just me. You cant take more energy from air than it has without sending the wind back the other way. Furthermore blockage effects limit the efficiency as solidity approaches 1 so there is no way this thing will ever pay for itself go ahead and try to dispute the fundamental physics of wind power but I'm afraid you have been scammed too
Nice thinking out of the box. Very inovative.
It looks like it would shake itself to bits and the surface area and mechanical resistance make me doubt that this is either practically function or the best use of materials for energy collection.
Amazing. Between 1 and 5,75 Watts being generated there. That's not enough to power a single average LED-bulb.
Oh I got 1 and 16W from the meter readings, though considering the obvious complexity [and cost] I would certainly agree.
That was the V.I supplied to the motor to make it go round and round.
They have a bigger one designed that will power 2 LED bulbs.
hmmm... 1 led..... 6 volts at .5 amps
oh wait your right, soon as you plug it in that thing will stop dead
50 of those short towers makes 20 kilowatts. Impressive especially the design! Solves the bird and blade erosion problems too. I think you have a winner and the decentralized aspect will not only cut costs but will work well in India. India is on its way to a huge change in it's society along with the electrification of all developing countries. Once there were electric lights in America everything changed. The biggest was work, which could now be a 24/7 affair. It doesn't work well to work in the dark or by torch light so people didn't do it unless they had to. Lives began to move twice as fast and everybody loved that. This meant production around the clock and more jobs for everyone and we loved that too. This is what's coming soon to an undeveloped or under-developed country near you and it's going to be massive.
It's not even going with the wind direction if you watch the trees in the background, lol. Thing is probably a dough mixer from an old bread factory
A 3 axle gear box requiring lubrication and periodic maintenance checks is suppose to be lower cost? It also looks like it is not self orienting (the blue mechanism looks like a hydraulic actuator to turn it in the right direction. Even the website says "Saphon’s aim wasn’t to improve the current wind turbines technology"
That's where my old saddle-light dish went! lol
Simple test of an efficient design: imagine reversing it's function. Imagine this as the propeller on a small aeroplane and ask yourself, would it fly?

Put this design on a sail boat. If the wind pushes the boat, ask yourself if it’s efficient.
I should’ve typed boat, not sail boat.
Interesting design . But wind-turbines derive their energy from the length of the load-arm . For example : short length (diameter) of rotor is small power , long length of rotor is high power , because the longer the lever or arm (blade) of the rotor is , the more the wind can exert load on the axle of the rotor , and so on the generator . No matter whether it is a propellor , or this system . It is analog to the system of the lever , or like a crow bar . I also think this system is more prone to failure due to its more complex functioning than a more simple and therefore more robust rotor-system . The more simple the system the lesser the wear and tear and thus the longer the lifetime . If the disc is made bigger , then the energy output will be higher . That is also why the present generation of wind-turbines have such huge propellors . The long the lever , the higher the load possible .
Efficiency is more than power. It can refer to the ground space utilized, for example, the noise produced or the number of birds killed.
It's amazing, you just plug it in and away it goes!
Yeah Hah,hah,.!. that was my fi rst impression
20V and 30 milli amps for those light bulbs? Are you kidding me? It's a fraud.
It looks like it would fall the hell apart at higher rpm. Strange design.
It gets pushed by the wind on one side and pushes back on the other....that makes no sense...also looks like a real vibration maker with that crank shaft. Might make a better sex toy than generator.
It does.
totally agree, another technology SCAM
I needed a good laugh this morning!
New genre of comedy in Tunisia!
Covert 80% of the Wind energy to electricity?
How can anyone measure that let alone be able to capture 80% of the "Wind Energy".
What does that even mean?
It makes no sense !
Unintentional hilarity!
As a power generator it looks catastrophic. But as a CETI radiotelescope it's awesome.
IT IS NATURAL MOVEMENTS HOW THIS CUP WILL ACT IN THE WIND ,BUT IT WILL BREAK SO EASY IF THE WIND IS STRONG,AND THIS KIND OF ARTICULATION WILL MAKE IT UNDER STRESS ALL THE TIME,IT WILL WORK BUT IT WILL NEEDS CONTINUOUS MAINTENANCE AND WILL BREAK,SINCE IT IS NOT LIKE THE MOVEMENTS STURDY AND IN ONE DIRECTIONAL PLANE TO REDUCE THE STRESS ON THE TURNING JOINTS LIKE NORMAL WINDMILLS
No way this is more efficient than a normal prop. To many moving parts too.
If it ain’t broke, don’t fix it.
Yeah and you can't beat coal fired power stations. hahahaha
I think that red light on the unit might be all it is able to power.
Anton Nym Sorry, that runs on battery.
It couldn't even power that.
If you look at your video you'll see a wind indicator which a far better design for generating energy. 3 cups any size will do the trick charge bat use inv to drive loads
That's funny
Mankind still has humour
This is a drag device. As such, it's going to be absolutely left for dead by devices that have blades
"twice as much" breaking news Albert betz died from a stroke then he heard this news
My very first impression is bad design. Looks very inefficient and will break in a couple of days.
Yes, I support you.
it will break in the first hour, after scientist have been fighting hard to perfect a rotation machine without eccentricity, lo and behold, another SCAM

GENIUS
I have been watching these siphon wind turbines for several years, the fact that I have never seen one for sale proves that they DON'T work
So brilliant ....
When they claim 80% that's a red flag. The highest possible is the Betz limit (no matter how strange the turbine), and that's 59%.
Yes the thing is utter lunacy. Albert Betz made some gross assumptions in his reasoning, but also drew attention to an otherwise overlooked fact.
Another fact that is overlooked - particularly by "windfarm" designers - is that a Turbine has opposite " economy of size" to that of an Alternator.
This makes the combined economy of size, a necklace- shaped function of Size. (on a "log". scale, i.e. x times so much per scale division) there exists a size region of lowest cost per unit of energy supplied. This is the region of size where the two components cost about the same. In my (rather large) experience, this region is around 0.5 to 1m diameter !!
Indeed, Don't forget Mr Betz!!
damnit! my girlfriend saw this and wants one now. she has this great recipe for scrambled eggs.
Very nice this type of wind will give constant torque to generator. Wonderful idea
Unic turbin.I like it.
I live in west Texas and the wind here can be rather high. There was a shopping center that had 5 small China made wind turbines installed to power the shopping center. They lasted about 6 months. There are large wind turbines all over this part of the state but they have to be able to withstand a constant wind of 20 mph to gust of 60 mph. I heard that the 5 small wind turbines cost about 10,000 each.
?ummmm ..... vertical NOT horizon blades solves that issue
google 'tension turbine' it provides more power than the 3 blade, and is vastly expandable. the ferris wheels in NY prove it!
certainly innovative.
I'm confused as to how this works and what sort of sails the Carthaginians used back in their day.
we'd had a similar design in USA but we have the the large turbine blades.
More like the blue thing behind is doing all the work. It’s a motor. The action is more mechanical than wind generated. Someone has eluded the same already.
Hay que colocarla en un tunel de viento y medir la eficiencia, asi de facil. ( yo estimo un 15% )
doesn't look that efficient to me, its blowing about 20mph at ground level, yet the saphona thing is intermittently working. I'd get about 500 watts with a 6 blade, 3foot blade length 1kw turbine
Da wird man ja Seekrank vom zuschauen
I applaud their efforts in attempting to replace the "bird guillotines" we have now.
It can be destroyed absurdly ease, super unstable fighting against strong wind it won't last 2 minutes. Forget it
Kaipogan+ but it could retract, but you are right. I'm happy they are trying though, even a stupid idea could spark a brilliant one! quote Ben Harkness-Brown
LtHarkness187 It is not a bad criticism I am just saying cos I have experience working with wind
As an 'alcoholic' (more just relaxing to me) I get threw 1.25lt of Johnny Walker Red Label 40% maybe a little more every 1-3 days, I have to work so I stop drinking 4-hours before work its the work that stops me, but intelligent enough to know work funds this degenerative life style? Its like that catch connect 4 "uno that works" when you need work, knowing the hard work pays for such a degenerate behavior?....... well that's how hard my dick is right now..... I too have experience working with wind! they(()) their really should be sarcasm text.... for better users kek..
Jason Poole + Hence a Retractable type wind model would be more advisable and I'm sure are being analysed and tested, stupid idea's spark insanely inconceivable idea's Quote "Ben Harkness-Brown"
That might be the worst wind turbine I’ve ever seen.
Boy, were they ambitious with the number of bulbs on their display board, or what?
At 0:47, we see voltage (apparently) between 20V and 33V. We see current (apparently) ranging between 20mA and 40mA.
That's a power of between 0.4W and 1.2W. As someone else mentioned, not enough to light an LED light bulb.
On a really windy week (month). they could harvest 1kWh in, what, between 40 days and 120 days? At $0.16/kWh, that'd be about $0.50 and $1 per year.
We're talking a really, really long return on investment!
Maybe the could put two or three garbage can lids up there and double the power.
Or build a wind farm in a foreign country!
With a wind farm, maybe you could light a single light bulb!
wow! a dish shaped blade
It does make sense, instead of two blades it is one, I get it, just don't know the proper terminology to describe it.
keep going you are close guys!!🔝
What happened when strong wind hits that wobbly thing lol that will fly like a ufo
Awesome. Keep your chin up and keep trying.
Did they thinks the vibration can make it collapse ...
Powered by the sound of one hand clapping?
well at least they tried. I haven't come up with anything better , how about you guys?.
yeah, google 'tension turbine' several times more efficient than the 3 blade, and is vastly expandable.
I am so sorry to tell you this but your accent is so strong I cannot understand what your saying, I tried to watch several times to no avail. I thought nothing could be worse then syn-voice, well I found it this morning.
So you know im so very interested, I wish I spoke Hindi...
Ronald Reed Easy to understand when you are used to a bit of international English.
it look good idea and super diversion from long not so nice wind mill
This is just to stupid. It's suppose to create energy in spite of also creating its own resistance to the contrary.
Yep !! This is just supposed to make money ;-)
It seems more like a Monty Python video, than real life. I have a feeling this thing only "generates" publicity for grant money.
is there a dwarf inside to make it moving..?
@ Erik J
I can only hope you're joking...
First, there is no perpetual motion of any kind, it defies the basic laws of thermodynamics.
Second, there is no pressurization of any kind occurring here, and even if there were (which there isn't) the "pressure" can never exceed atmosphere, 14.7lb/in^2 at sea level (where they are) and the wind being a fluid will not allow itself to become pressurized when it isn't contained in any way and will just flow out and around any supposed containment this preposterous design would attempt to achieve.
Third, this video is two years old, and you haven't heard a single thing about this ludicrous design of bladeless wind turbine elsewhere... why exactly do you think that is?
Keep in mind, wind turbines/mills have been tried in numerous configurations for literally THOUSANDS of years, and only now is this magical design magically appearing and so great, save for the fact that the demonstration can't light even a single bulb in the array because it displays on the multimeter at 0:45 at around 33 volts and about 0.11 amps, so maybe around 3.63 watts. Oh, and that's DC, not AC, so if you wanted to use it for a household appliance that uses AC it would have to go through an inverter, which would be "lossy" as well.
This isn't me saying it's generating no power, this is THEIR OWN EQUIPMENT saying it's generating hardly enough wattage to light a SINGLE LED bulb used in a keychain flashlight.
So, they are fighting against mathematics, physics, thermodynamics, and reality... which is why this scam died out over three years ago and merely managed to bubble its way back to the top of the crap heap in the last two years to make another round of april-fools.
Nobody Uknow
I think you misunderstood my use of terms ... obviously PRESSURE cannot be accumulated as the air can flow around the bowl... I was referring to the FORCE of the wind, which is trapped inside the bowl like the wind on the sail of a boat. You do understand how sailboats work right? Although Sailboats have no regard for atmospheric pressure, magically the FORCE of the wind still makes them move anyway. Have some common sense bro. Additionally you also have no idea how the geometry of the toggle system and the gearing angles and other internal mechanisms are set up. It is true that is isn’t generating a lot of power, but that has nothing to do with the mechanics. The generator is obviously not efficient but again... this is a prototype and those shortcomings can be rectified. They comment very early on about the efficiency. Look at the small size of the thing. It seems apparent to me that it would be useful in situation where a large bladed turbine would not be feasible. I think that’s the point. A small footprint solution for specific situations. It’s seems evident to me that more work is needed, but I see this as a concept... not a finished product and I’m giving them credit for creativity. There must have been some necessity for them to design it the way they did. I don’t think they meant for it to replace the huge wind turbines already out there... it’s a solution for a specific situation.
This is what inventors do, they work as much as they can on a concept until they need outside help, either with technical assistance or with finances. I don’t see them as scammers. How many products have you invented and brought to market? There is a difficult process to navigate. And There are countless products that never make it to market for many different reasons. To say that a lack of mass production is equal to lack of validity just isn’t true. Big corps couldn’t care least about the environment. They just want fast easy money, and they aren’t concerned with helping out small niche groups or dealing with specialized products unless they can rape people on the pricing. This is why specialty products are usually reserved for the wealthy because that’s the only way they can make the profit margin they require for niche products. obviously isn’t a fortune maker, but it could be useful in certain situations.
And you’re over reaching on the single led power consumption. 3 Watts is plenty for a small led panel which can provide a quite useful amount of light. I’ve developed products in the LED industry. A Walmart LED flashlight is far less efficient than a high end set up. There are more factors than just the led itself. No one uses the DIP or bulb that you are referring to. They use SMD chips, and along with a good driver you can put out a very good amount of light with 3 Watts. In any case, I doubt that they would be tapping the juice straight off the generator, they would be charging batteries with it, which this would do just fine as is. If left overnight to charge it could charge a full bank of 8 to 12 car batteries overnight. Which could be very useful. Obviously not as a continuous power source, but as an emergency back up system. It would work for a small outpost in an emergency situation.
I can see the failure points clear as day.
They didn't TURN with the wind! BIG fault! The motion alone will tear this thing to pieces in NO TIME!
They use these for all their power in Wakanda.
that explains why they have light bulbs that only need 1/5 of a watt to light up....
Looks like someone forgot to tighten a screw. Wobble wobble 🤓
looks like it wouldnt last long in a sand storm
Delenda Cartago!
Looks really cheap to make that very inefficient device that will wear out in no time. I unfortunately do not see them for sale almost two years after this is posted! Must be GOOD!
Why they looks like praying for the device start to work?
5 years... there is no changing game = Failed.
Cannot compete against new 12 MW off shore wind turbines, too little too late.
This is stupid. There isn't enough surface area to generate enough power and the design looks like it will never last. To much maintenance.
The best windmill is not the most efficient one, it is the one with the least moving parts. This one has many moving parts and is very small, which is why it is trash.
Looks like a mechanical nightmare...that would shake itself to pieces or at least create and enormous amount of wear on parts....
Haha what the fuck is this!
Show us the math in comparison with a three blade turbine
It’s shaking about more than gramps with Parkinson’s
so, I see they're in an area where the wind is pretty constant in one dirrection... thats because it has no way of turning itself into the wind.. number 2, it will never exeed 200 ish rpm because a rotating cantalever will destroy itself unless you counter balance it... hence thing thing weighs twice as much as it needs to... hence the gigantic pole that normal 3 blade gen's are on a broomstick.
and finally , we have trees ya stupid desert ppl. lol
Wow! Not just hogwash technology but also 10 times more distracting than a normal wind turbine and 100 times more unappealing.
Drumchef hubdad ,,Yup ,very distracting,,,,, to wildlife, birds,,,and fish! Memorizing as they hypnotize their investors...
Great stuff don’t let it get covered up.
What happens when the wind stops? uhhh..... yah.... try giant batteries.... theyare making them as we speak.
cheaper????? :)
Just like Futurism's blade-less turbines. Just not enough swept area, to produce any more power, than a traditional horizontal axis turbine. This may, or may not be competitive with a savonius vertical axis turbine. (55 gal. barrels, cut in half)For efficiency this poor, there are much simpler, more reliable designs.
This looks very cool but by design is the least efficient, even less than the savonius design.
Why does this thing look like a hoax?
you need to know the betz formula / law
If global warming was man caused, if "fossil" fuel was actually scarce, I would still not be interested.
Cant be serious. It will consume more power than it makes to rotate arm .
Fail
It is better than vortex which won the H2020 grant!!!
Wow
Not good. Its inefficient. The eay it moves its so restricted. Also there is to much drag.
It’s already broken
