That's basically a Savonius turbine. And you didn't mention how many of these designs would need to be installed to create the same volume as one of the masted horizontal axis bladed versions....
A number of VAWT's can be installed at different points and sides of the same tower to equal the same power. The best analogy would be having one ostrich egg or a doxen chicken eggs. And if one is being repaired, the others are still going.
As described in the video, the industrial one has upto 3kW. You will need 333 of those to match the conventional HAWT. But, I guess the price sum of all those VAWT would be much cheaper than the HAWT.
@@NuthanPrasanna Well im sorry but its not that simple, and from your comment you either haven't actually looked at their spec sheet for that turbine or you don't understand the industry and whats available, or both, its not a case of simple math by doing 3kw x 333 = the same a one HAWT, if only it was that easy lol... and also the 3kw is taking in to account a lot of assumptions and also unreal assumptions mainly being they will have a location for provide wind speed to produce that, even if it can achieve 3000w which I do not think it can, it stays in one piece. I had a look on the Icewind website, which is very basic, and not a hole bunch of test data available what so ever. The test data for proof available shows on the largest rated turbine the RW500 a maximum power output of not even 1kw on the test data chart and also has a rated speed of 10 m/s which results in the 500 watt power output. That fact alone is a terrible output. If you take a HAWT HP turbine using axial flux alternator, with the closest matching system (which I will use a smaller one at 350 watt to give the Icewind the higher output advantage) The HAWT HP turbine at 350w rating running at 6m/s would result annually in 888 kwh, which is way above the annual output of the icewind RW500 with 150watt more at the alternator/ generator providing the power. VAWT CAN NOT compete with a HAWT and not even close, which is why you do not see large scale commercial installs of these.
@@mannebk9978 VAWT are less efficient than HAWT, so what? They are superior in all other aspects. The efficiancy of VAWT is between 30-40% while HAWT are at slightly above 40%. The other diference us that HAWT are likely to get installed in places with the best wind quality thus naximizing the energy yield, for VAWT that is not the case, they are likely to be installed whereever is some funds left to get some extra electricity. And this is a concept that many people still do not understand: To get sustainable electricity we need to get every bit possible as compared to nothing. That means using every bit of space available in urban areas. Always remember that the alternative is none at all.
The turbine featured is a form of a Savonius vertical axis wind turbine, these typically have efficiencies of less than 17%, the common turbine design it is being compared to are 30 - 50% efficient at extracting the energy from the wind. there is another vertical axis turbine design, the Darrieus wind turbine, which is far more efficient than the Savonius turbine, at 30 - 40% efficient.
Just watched a video stating over $400M annually are spent on disposal of the short lived blades, in America alone. Non recyclable materials. Then there is the noise and physical hazards, along with the GSM driving wind velocities higher to the point (I believe) will destroy large systems. During the GSM the weather gets rather severe. From walking across the pack ice of the Everglades, to 300 mph winds across the plains. Times will be very rough no matter what we do. Preparing to survive it is more important than trying to change it.
@@ronnieince4568 why do I need to check out Betz Law? Obviously no energy conversion system can be 100% efficient, but some can be and are more efficient than others.
Too bad about all the up votes. This kind of BS needs to be discouraged. Vertical axis windmills have been around for a long time. They are not going to compete with large windmills that generate megawatts. They might compete with smaller windmills, but you'd have no idea of the possibility of that from this video. There is not a single quantitative fact mentioned in the whole thing about the windmill's performance compared to alternatives. Sometimes numbers matter and BS isn't all that important.
Yeah I typically upvote everything but had to go down on this one. Really garbage comparing little diy units to grid scale units… well the comments speak volumes already…
Flowind tried helix wind turbins 35 years ago. I invested in Flowind. Then filed Chapter 7 a few decades ago. Today, there are wind power mechanisms with no moving parts. That's an innovation.
I have seen this before many times, somewhere within the last 25 years. This seems like an already invented product that recently just got facebook support.
These "advertized" turbines can't even make 1% of the large industrial wind turbines that it bashes. Power production formula is related to square of the area that the blades cover during rotation.
@@DevonDandy I understand smaller scale wind turbines advantages, but it keeps comparing itself to the conventional high power high scale wind turbines
There’s a reason why the wind industry settled on the three bladed, horizontal axis turbine, and it wasn’t aesthetics. People have been pushing vertical axis turbines for decades and the laws of fluid dynamics keep saying “no.” The inherent turbulence and upwind travel of the blades lowers the efficiency of these into the teens. Just stop it.
I like this design because it could actually be scattered throughout urban areas, whereas there would never be a large traditional wind turbine installed anywhere in a city. Then we'll have two great power options for large scale and small scale
@@Nikosi9 NYC? What is that? do you know if there is much energy available from that wind. I know that the traditional wind turbine wants long runs before and after the turbine. The lack of urban turbines points me to think it is not as good as it appears. I do not have any figures to say one way or another.
AGREE ; Large scale is not very effective and kills way more birds than small scale or VAWT.... Take a look into Flap Turbines. They are a new type of Cycloturbine that is extremely efficient and easy to build. Small Wind is Win Win Wind
yeah, great for integrating into existing development, but there's a reason "traditional" turbines are still the way they are for dedicated high capacity production. the huge radius of the turbine blades is a feature, not a byproduct. it's to catch more energy from the larger area
About fifty years ago a friend showed me the same invention, with an extra boost, provided by a hoop much larger than the diameter of the centerpiece, fixed to receive a wheel attached to an arm fixed on the central axis, and resting on it, driven by the centerpiece, but as it's further from the center, more rotation.
That wind turbine has an maximum efficieny of 20% (hard mathematical limit), what means that the overal designs will reach 15%, probably. Currently used WT are at around >45%. So, you cant compete with solar, cause you still have moving parts and necesity for maintenence, and you can´t compete with HWT because this simply can´t meet the efficieny. This will not leave the bus stations...
On my afternoon walk today, there was a leaf or piece of debris blowing alongside me. A gentle puff of wind suddenly put it far ahead of me. When I caught up, I noticed it had and unusual shape. I immediately thought it might make a good wind turbine design. My 5 minute search brought me here. This is close to what I saw. All the best designs are already part of nature. Glad to see someone has put this one into production for a wind turbine.
It is funny how you call "traditional wind turbine" to three-blade horizontal axle turbine, which science and experience has proven to be the most efficient design, i.e. the one that grabs the maximum power from wind. VAWTs always have the same problem: the blades move against the wind as they rotate, and that consumes power. It is so simple to see that I am amazed you are selling it as a revolutionary possibility.
Yes, traditional turbines are huge and this one is small. But those huge turbines produce megawatts, but the Ice Blade could just power a couple of light bulbs.
the main reason that horizontal axis wind turbines are generally used is that they convert wind to usable electricity more efficiently; when you combine that with the economy of scale and mature designs of the horizontal variant its pretty clear why they're used for most applications.
That depends on how you define the efficiency. Traditional horizontal fans wins out if you only consider the area they occupy. But that may not be the most important factor as the world is huge. What matters more is energy produced compared with cost of installation or service cost. Traditional horizontal fans are so terrible for both that they are almost not worth building. The vertical type shown in this video on the other hand is very cheap, that makes it not only better then the horizontal fans, but also compete better with other alternatives. It doesn't hurt that it's also less noisy and intrusive making it easy to put anywhere.
@@znail4675 the range of wind speeds that thy operate in is greater Traditional horizontal fans need a big separation because of the turbulence they create
Silly narration with EXTREMELY dishonest comparisons between VAWT's and HAWT's as you're comparing multi-mW turbines to dinky 600W VAWT's on the ground! Multiple studies have been performed, by 3rd party engineering companies that show vertical axis turbines producing only a tiny fraction of the energy of horizontal turbines with ROI time frames of: 600+ years. There's nothing new about VAWT's, they've been around for many decades, even like this Icelandic dude's style and they still produce little-to-no energy. I know, I've sold thousands of small wind turbines over the past 15 years and have one in my own backyard, powering my own home, on a 40' pole. Putting ANY wind turbine on the ground will be a guaranteed waste of money as wind turbulence and low-wind speeds will starve the turbine. Don't waste your time and money on dumb ideas, buy cheap solar panels and call it good.
@@chenqin415 Look up Betz's Law, which states that at the maximum you can in theory obtain only up to 60% of the energy contained in a certain area through which air flows, in realistic conditions this number will be lower. As the area is very small for these small turbines and at low altitudes the speed is low, you'll only get tiny amounts of power. For the same amount of money you'll get much more power with solar panels, even at high latitudes. On top of that PV panels last longer and won't require (as much) maintenance, hence the $/kWh is much lower. For large wind turbines however, the wind speeds are much higher, for more hours in the year, in a much larger catchment area. Therefore, wind turbines in the MW scale do have lower $/kWh, even with maintenance cost included. If small wind turbines could be as cheap, we would see them all over the place already.
Has anyone figured out how to properly dispose of solar panels after their useful life? How about the tons of batteries that must be used to smooth out the intermittency issue?
Nah man, this video has inspired me to convert old soup and coffee cans into wind turbines to power my house. *ENERGY COMPANIES HATE THIS MAN* *POWER YOUR HOME WITH ONE SIMPLE TRICK*
@@scottcantdance804 If your house uses a LED night light you got that covered :-) If you can get by with a couple hundred watts total you can power a house.
@@scottcantdance804 I have a much better solution. There is this black goo i found a kilometer or so below the ocean floor. If i bubble it in a cauldron i can use it in a internal combustion diesel engine to get FREE ENERGY!!!!!
Well, it isn't totally BS, but it is a very wordy (I mean "wordy", not "worthy") video pasted together from recycled material known since the 1970's, and is mostly an advertisement (I suppose, but I don't know, that the owner of the video got paid). It seems most technology videos on YT are like this. Some people who have zero knowledge of the subject might find it informative. I wonder how many IP violations were committed in doing this video :)
Since 2012, the average height of wind turbines installed in the United States has been about 280 feet, or 80 meters. Wind at that height is much greater than close to ground level. The video shown here is merely about 10 feet.
It can probably power a LED för a busstop or something like that. But I have in my backhead that ALL windmills that are below 2m in diameter is waste of time and can never produce anything connected to the grid. There is ”probably” a reason that all windpower turbines look the same. 🤔
@@vaktgunnar They are actually really good. But most verticle turbines are only 20 - 30% efficient, where our big three bladed ones are 40 - 45% So, good on a small scale, not so much for large scale.
@@SoralTheSol that's the general problem with wind power. It used to be worse 2 decades ago, but in the 2010s we hit a stride with wind tech that let us get it up 10-15% efficiency. Solar Power is also incredibly inefficient. Albeit, not as much. If we could stack maintain a 50%+ efficiency maybe, but we barely maintain a 10-15% efficiency at peak sun. Compared to wind turbines which are hitting close to the theoretical caps of 59.6. With 50% being the max cap of current high end turbines. 35-45% being normal... If we can downsize current turbines, and get the exact same output. That would be great otherwise it's pointless. Not to mention for each mW, you need roughly 1.5 acres of land... so about 4-5 acres for the maximum wind turbine on the market. Not to mention clearing the area of all fauna, and flora other than grass
@@icarusunited it's the reason why I keep saying that we should go full nuclear, until we have a better solution. Have the grid power by mainly nuclear energy, and have the wind/hydro/sun sources supplement it and grow as fast as they can, until we invent out fusion powerplants.
Im just a dude and day dreamed this design many years ago, and a few more. I feel like millions of people have. So im glad its being built. Seems like there are infinite basic solutions to all lifes problems that just need funding. Very inspiring to see someone just do it.
I have worked in small scale wind for 35 years and produced well over 160,000 small wind turbines - Please, this is not going anywhere. It is cute but a drag style design like this has been around for 1500 years. Sorry buddy -
One of these and a TeslaPower wall would take most houses off grid easily. It’s not really commercial unless you can drive massive loads like a typical grocery store needs. So this is a nice product, yes.
Here's my perspective (MSc in Renewable Energy Engineering) Most of what he claims is true in it's basis, but not accurately depicted. For example: Horizontal axis wind turbine blades are also moved by the pressure differential, like an airplane wind. Also the noise and vibration really isn't an issue, the shadow flicker is. But that only affects areas a few hundred meters around the turbine (depending on location, but it can be easily simulated before construction) also he compares the sound of a 5MW turbine to that of a 500W turbine. Also also, the vertical axis wind turbines he shows are all on ground level. You know what's weakest at ground level? The wind... That's why the comparison again doesn't make sense. The disadvantages he's talking about like that the turbines will be destroyed when the wind is too strong or the exponential cost, or that the orientation of the turbines are all way WAY overblown. They were problems, then someone came up with a good solution, so now they're not a problem anymore. The entire video seems to be just an ad for a technology that has been shown to be inferior. It's not like those vertical axis wind turbines don't have any use-cases, but... well I don't know of any, other than where you need a helicopter to access the area. That's where horizontal axis is too heavy.
Actually, not that new of an idea. Similar devices have been made from split oil drums. The rub is that the wind mill is far more efficient. This is why we don't see farms of this type. There isn't much of an escape from high placement of the generator structure, as there is more wind higher up. This structure can be placed somewhat lower, but will still have to be put on top of a pole or tower. Whether this is feasible for mass power generation depends on the efficiency price paid for going with this set up. How many kilowatts per acre can this device produce?
I can see putting them on high tension, cell phone and some power poles to feed directly into the grid. I also like the idea of SMR's (small modular reactors) to generate electricity.
During the lock down, when the pollution cleared, the planet warmed up half of half a degree. The theory that pollution is warming up the planet is questionable, time to raise taxes...
It took only two months for Saethor Asgeirsson to develop his new wind turbine in his garage. For the last two years he's been working on a way to efficiently bring the wind into his garage.
I live in an apartment homes near me only one has solar panels he showed me his electric meter running slow hardly moving he said on a good day it runs backwards
My friend lives in a council house (home thats rented from the government basically). He has just bought a new electric car only hes not allowed to charge it at home. He'll get fined if he does so...yeah goin really well so far.😐
It's to keep air temps in attics cooler. Since heat rises, attics are always hotter. But due to thermal equilibrium, the hot attic will warm the cool room below it. The vent acts ass a vacuumed sucking hot air out as apposed to blowing air in.
Honestly I think the best way is to use miniature version of traditional turbines (radius of not more than 2 meters) and place them on each of the buildings that are reasonably tall enough.
People can't grasp that wind energy is unpredictable, insufficient in most areas, utilizes moving parts with limited life times, meaning replacement costs!
I noticed that these wind turbines work low to the ground also. It seems to me that the tower with ONE turbine should be outfitted with at least two turbines and maybe 3 or 4. Plus why cant you build them as tall as a traditional wind turbine with however many you can deploy up the tower like 10 or more? Just asking? Thanks
Yeah, and in my high school science class in 1970 we watched a movie telling us that if we didn't change, the earth would be a burned out cinder by 1990... Uh Huh...
And in that time, green energy production has boomed, helping curb at least some of the fossil fuel use that would have destroyed us by then. We haven't quite reversed the problem, but we've managed to slow it slightly.
I thought we were gonna become a popsicle in the 70s? Besides... I think the whole idea that a trace gas that comprises roughly 4 one hundredths of one percent of Earth's atmosphere does anything other than feed plants. Concentrations of that same trace gas were as high as 8 one hundredths of one percent in the distant past and the Earth was a lush green paradise by comparison to today. That was way, way before SUVs could join the party, BTW. Additionally... we don't really know how much mankind contributes to the total trace gas emitted - I've seen lots of BS claiming otherwise, but, It's just that. BS, IMHO. BS that comes from altering data, hardcoding 'desired outcomes' into simulations, and plenty of other well documented deceptions, all to create the "perfect scheme" to separate the public from their money while trampling on their God given rights at the same time. BC it's all for the children, or whatever the BS du jur happens to be... All in my cynical, yet humble, opinion. P.S., ask yourself a simple question; why does nearly all "climate research" funding go exclusively to one side of the debate? Greed coupled with lust for power, supported by made-up pseudoscience, never ends well for anybody. Enough said.
He starts talking about the new turbine at 2:50, more importantly the guys beard is red, though he doesn't have one and somehow he knows the guys descended from Vikings, all the important stuff we need to know.
This turbine will be crucial in 2000 when all computer goes down, or at 2012 when the world ends, maybe help us to cool down the global warming or balance the following global climate change and at the end definitively help us to warm up on the upcoming ice age....oppps I said too much the ice age part supposed to be advertised a few years from now only.
I'm happy that we have the earth 1 degree C over the little ice age, when people was freezing and starving to death, and that crops are grownig better with enough carbon dioxide in the air. Something humans hav'nt achieved. Let's hope that we can continue to have an atmosphere rich in carbon dioxide and suitable temperature. To be on the safe side we need higher temperature and more carbon dioxade.
This is a very old system. And anyone build it with floating magnet train system about ten years ago. I don't know why forgot this vertikal Maglev wind turbine.
I don't think it would even have enought power to recharge a single phone xd. Look at the poor light on the bus stop. It can't even be seen at night xd.
This idea, while not new has a lot going for it, not least the simplicity of design, the asthetics is better than that of the typical wind turbine. Maintenance should be easier on the vertical shaft wind generators, they could even be set up along suitable boundaries and act as both power generators and windbreaks. It would likely be a good idea to provide them in muted colouring that blend in with the environment. More robust versions could be installed in larger waterways, or in the sea where prevailing, or ever changing currents would power the turbines. The sizes could be larger as long as the foundations holding the turbines match the maximum forces they ever could encounter in a severe storm scenario. Off-cause, it might be easier just to use more smaller turbines rather than more challenging large versions of those turbines. Mass produced the cost of such vertical turbines for use in the air or under water should be competetive, or cheaper than alternate green energy generation methods.!😀💖
cost of vertical wind turbines Vertical Wind Turbines - Prices & Costs The purchase prices of vertical wind turbines are usually no lower than horizontal wind turbines. For the entire small wind power market, there are significant differences in prices and specific costs per kilowatt of power depending on the manufacturer and wind turbine model. The price range is between 3,000 and 10,000 euros per kilowatt of installed capacity. Due to aerodynamic disadvantages, system regulation and storm protection is more complex in vertical wind turbines. For example, horizontal wind turbines can be turned out of the wind as a technically elegant storm protection; this is not possible with vertical wind turbines. A vertical wind turbine therefore requires special technical solutions for system regulation, which is reflected in the construction costs.
Good for small applications; also you don't want to accidentally walk into one of these at night, or have a child put their arm into one. (assuming if mounted at ground level). Currently industrial wind turbines will generate 1-3MW of power each in ideal situations (typically their only installed in such locations). To put that in perspective that is 1000-3000kWh, or 1,000,000-3,000,000W, these as per video suggest they can generate up to 5,000W. Obviously this is GREAT for individual homes or small applications and may actually be better then solar in many places with decent wind. The only way this could be used to supplement a commercial power-grid however is if their installed over a great area on rooftops etc.. (light/power/mobile poles even). The downside however is having to deal with maintenance, mean failure or defect times would be quite critical for such a setup. Question: What energy/cost would it be to downscale a commercial 3MW one to 3-5kW? because that's the ONLY real way to compare them. Its like comparing a dinghy to a cargo ship.....
Why does everything have to be perfect to be meet your requirements????? Nothing is perfect. Yes it can work for small applications. Yes, it can power a home. So WTF more do you need for it do///// If it works for a house and can be used in 50% of residences think how much that would save for homeowners and the environment. Ease up with the whining. Getting off the power grid would be a major accomplishment for most families. I can use a dinghy. I don't need a cargo ship. Easy to find fault in anything. Just look until you are successful. So what is your solution????
It can be a great technology to use with the wind turbines we use today. To think they should replace the classic mill is crazy, but they can be used in many places as a supplement.
This video doesn't make it obvious that those tiny, slow-spinning turbines near the ground don't have even 1% of the capacity of the giant machines. A nice idea, but they are not equivalent at all.
@@shoddyproductions9793 wait so you mean to tell me! You got hurt cus I made fun of yall.... for saying these make wind?🤣🤣🤣. You two prolly almost get blown off the hywy when you pass a wind farm huh🤣
This is in effect for years now. Vertical axis wind turbines have a very small efficiency roughly about 10-15% and there are tons of other parameters to be optimum for continuous power production.Won't be cost effective to install one even in a household. None of the wind turbine giant corporates have ever installed a big vertical axis wind turbine. :)
Have been using solar and wind power for years ,wind power is perfect if you live near the sea , less maintenance you don't have to worry about cleaning the glass ,night time is when I'm using most power in the morning my batteries usually are fully charged most experts underestimate how good win generation is. In Australia unfortunately if you use wind generation on your house with solar panel, rebates you will do all your solar rebates I believe this is to help protect wind generator farms
Same here, 40 years of wind and solar use. Nothing beats wind for the NIGHTTIME, but now that I'm grid tied PV is my fav. Hard to beat no moving parts, noise, and not tower required.
Cities should have clean air, but climate chnage is due o geological cycles, actualy the inclination of the earth in thr 70s weas aroundf 23° and its now slihtly over 24°, tht makes the summerhooter and the winter colder.
Add a electric leaf blower from Walmart for $30! Make your own wind! For solar power just add lights! For hydro power just pump the water back into the lake!
Vertical axis Wind Turbines (VAWT) have been around for years. This is NOT new technology! However, it is promising in it's smaller design. If the wind can make it spin, it can produce electricity.
You are right. The first VAWT design shown is one of the oldest. In addition, wind turbines now feather in high winds. It's not such a problem as the presenter suggests. In addition, the bird issue is a canard that is virtually meaningless for several reasons. First, cats have driven 34 bird species extinct (Mother Jones), second, buildings kill the most birds, third, there are designs and coloring (stripes) that can reduce bird fatalities, and fourth, if renewable energy isn't grown, more birds will be killed by global warming than all windmills combined.
When you consider that burning gas is green tech, well, this makes the gymnastics of green tech quite interesting. The same thing about electric cars, that producess many toxic waste with their 5 year old lifespam batteries...
This is nothing new I saw something similar at least ten years back. They are small because their power generating capacity is tiny. Comparing the two is like comparing a row boat with a cruise liner.
Wind turbines DON'T produce a lot of noise or vibration, they're very quiet and exceedingly stable... This video is really full of a lot of ridiculous inaccuracies...
vibration is usually from blade delamination and unbalanced props. none of the points in the vid are ridiculous inaccuracies. I have yet to see a windmill incorporate what was used in prop airplanes for decades, blade feathering. a much better idea than having to lock down the prop in high winds.
Those traditional look wind titans are so high because the wind is much faster at that height, there seems to be a blind spot in this mini-documentary that doesn't address this.
Years ago my late brother drew a design for a Savonious turbine fashioned from an oil drum, sadly, he never had to opportunity to make one. Since then I have sometimes wondered why this style of turbine has not been adopted. Those who comment here to rubbish this design forget that, being able to place these locally without the problems of conventional turbines, they overcome the enormous cost of transmission lines and sea proof platforms. They can compliment conventional turbines, not replace them.
I built a Savonius turbine about 15 yrs ago and it came out great. I used chimney metal, split lengthwise and mounted on 12" dia acrylic sheet so overall diameter was about 12". It worked great, but then I tried to build the generator part. Not so good at that. So now that I'm retired, will build another turbine - maybe a little bigger - but then just buy the generator and go with that. If I'm really smart, I'll v-log the build and post on U tube.
One reason the large conventional turbines are gigantic is because wind blows more consistently the higher up you go. These are great if you live in a place with consistent winds at ground level, but there are many, many places on the globe without consistent, let alone any wind at ground level. They aren't the silver bullet the poster proposes because of this. Elevating them presents a load of problems not mentioned here.
At least he was woke enough to include a black female engineer. Very important that it not be a white male engineer. You know, something that is way more likely to exist.
I’ve seen a video showing this type of turbine situated on the divider of a highway, activated by the passing traffic. Seems a way better option than the massive turbines that are so environmentally devastating in their installation and end of life, which I believe is about 18 years, when they are not removed totally but just perhaps the blades. Certainly, the hundreds of tons of concrete and the steel reinforcing that supports the base are there forever.
Read up before making claims. The earths temperature has more to do with the sun and Traditional windmills are as a propeller also a spinning wing. By the way. A vertical axis of rotation is structurally much more sound, however the wind load still requires a very heavy foundation. Guy wire systems still have to tie into something heavy.
You do know that the "preverbial frog" was lobotomized before the experiment right? Healthy frog won't sit for you in a pot regardless of it's temperature. :D
While some Vertical Axis systems can reach energy efficiency close to those of conventional rotor blade, they suffer in areas that make them untenable commercially, for example the primary reasons a Rotor Blade generator is tall is not because of the blades, though larger blades increase efficiencies, but because of reasons of Mass Air Movement, as there is more energy the farther from the ground effect, this is why Horizontal or conventional Rotor Blade systems function best as large off-shore sea based systems, So even Vertical Axis systems will need to be built high, and this creates issues with servicing the Gearbox, as it is these mechanical issues that increase Vertical Axis operational costs and decrease their life spans. There has been some fascinating research on Vortex Based models but no testing systems have been developed as of yet.
I had seen a discovery documentary on this design ten to twelve years ago and I think this design was first originated and commercialized by a Canadian firm....I may be wrong
Well, the Savonius wind turbine was invented by the Finnish engineer Sigurd Johannes Savonius in 1922. However, Europeans had been experimenting with curved blades on vertical wind turbines for many decades before this. The earliest mention is by the Italian Bishop of Czanad, Fausto Veranzio, who was also an engineer. He wrote in his 1616 book Machinae novae about several vertical axis wind turbines with curved or V-shaped blades.
Unpopular opinion: Man will find a balance between Co2 productions and the consumption of the same. We will figure it all out. We will have our cake and eat it too. Humanity will go on for hundreds of thousands of years on earth.
NASA! they’ve been “ reimagining” the historical global temperature records again, which now , coincidentally, show an increasing trend, and also , double coincidence ! , correlate with the recent increasing CO2 measurements . 😂😂😂. The cult of climate continue at speed to delete and conceal any actual science or data that discredits their “ settled” climate science.
The fix to both these is size, but as he has not fixed the crushed bering issue that is why we have horizontal wind turbines and vertical now it's a red herring
A typical household may need 5-6KWh per day , so given 500W maximum power of wind turbine, 10-12 units would be necessary. Powering the household would be possible only in rural areas, not cities.
Meanwhile, a regular nuclear reactor somewhere in the world created about 1.8 MW while watching this video, 13.000MW per hour, some say they average about 1GW per 24h. So, how many of these do we need to compensate 1 Gigawatt? Let's average about 1500W for the industrial yeah? Hmm, we need oh that's a funny number... 666.666. Calc yourself... Divide 1 Giga (1 million) with average watts (1500) = 666 666.6666666667, that's how many you need. Question is, is it cheaper both environmental and economical to install 666666 of these wind turbines, just to compensate for 1 nuclear reactor??? How many reactors does the states have? Oh 54 of them... So I guess the complete goal to replace all reactors is.... 36 million wind turbines.
Biden is walking in Obama. Obama said that electric prices will "necessarily" have to go up so wind and power will be economical. Also I wanted to build a vertical windmill just for fun. I found that this type of windmill is a fraction as efficient as a horizontal windmill.
I would like one of these rather than have solar panels. My roof has too many obstructions, windows for loft rooms, velux roof windows but these would work well on my chimney stacks.
That's basically a Savonius turbine. And you didn't mention how many of these designs would need to be installed to create the same volume as one of the masted horizontal axis bladed versions....
A number of VAWT's can be installed at different points and sides of the same tower to equal the same power. The best analogy would be having one ostrich egg or a doxen chicken eggs. And if one is being repaired, the others are still going.
@@aphilipdent Rube Goldberg time....
The HAWTs range from 1MW to 6MW. It usually costs upto a million dollars to set up one 1MW unit.
As described in the video, the industrial one has upto 3kW. You will need 333 of those to match the conventional HAWT. But, I guess the price sum of all those VAWT would be much cheaper than the HAWT.
@@NuthanPrasanna Well im sorry but its not that simple, and from your comment you either haven't actually looked at their spec sheet for that turbine or you don't understand the industry and whats available, or both, its not a case of simple math by doing 3kw x 333 = the same a one HAWT, if only it was that easy lol... and also the 3kw is taking in to account a lot of assumptions and also unreal assumptions mainly being they will have a location for provide wind speed to produce that, even if it can achieve 3000w which I do not think it can, it stays in one piece. I had a look on the Icewind website, which is very basic, and not a hole bunch of test data available what so ever.
The test data for proof available shows on the largest rated turbine the RW500 a maximum power output of not even 1kw on the test data chart and also has a rated speed of 10 m/s which results in the 500 watt power output. That fact alone is a terrible output. If you take a HAWT HP turbine using axial flux alternator, with the closest matching system (which I will use a smaller one at 350 watt to give the Icewind the higher output advantage) The HAWT HP turbine at 350w rating running at 6m/s would result annually in 888 kwh, which is way above the annual output of the icewind RW500 with 150watt more at the alternator/ generator providing the power.
VAWT CAN NOT compete with a HAWT and not even close, which is why you do not see large scale commercial installs of these.
Helix wind turbines aren't new. Don't call a company making wind turbines of a type an invention please.

@@mannebk9978 VAWT are less efficient than HAWT, so what? They are superior in all other aspects. The efficiancy of VAWT is between 30-40% while HAWT are at slightly above 40%. The other diference us that HAWT are likely to get installed in places with the best wind quality thus naximizing the energy yield, for VAWT that is not the case, they are likely to be installed whereever is some funds left to get some extra electricity. And this is a concept that many people still do not understand: To get sustainable electricity we need to get every bit possible as compared to nothing. That means using every bit of space available in urban areas.

The turbine featured is a form of a Savonius vertical axis wind turbine, these typically have efficiencies of less than 17%, the common turbine design it is being compared to are 30 - 50% efficient at extracting the energy from the wind. there is another vertical axis turbine design, the Darrieus wind turbine, which is far more efficient than the Savonius turbine, at 30 - 40% efficient.
Just watched a video stating over $400M annually are spent on disposal of the short lived blades, in America alone. Non recyclable materials. Then there is the noise and physical hazards, along with the GSM driving wind velocities higher to the point (I believe) will destroy large systems. During the GSM the weather gets rather severe. From walking across the pack ice of the Everglades, to 300 mph winds across the plains. Times will be very rough no matter what we do.

Too bad about all the up votes. This kind of BS needs to be discouraged. Vertical axis windmills have been around for a long time. They are not going to compete with large windmills that generate megawatts. They might compete with smaller windmills, but you'd have no idea of the possibility of that from this video. There is not a single quantitative fact mentioned in the whole thing about the windmill's performance compared to alternatives. Sometimes numbers matter and BS isn't all that important.

Most important question: what's the cost per kilowatt hour compared to other turbines?
@Oz A Yes!
These "advertized" turbines can't even make 1% of the large industrial wind turbines that it bashes. Power production formula is related to square of the area that the blades cover during rotation.
@Oz A roughly the same as normal windmills

@@DevonDandy I understand smaller scale wind turbines advantages, but it keeps comparing itself to the conventional high power high scale wind turbines
There’s a reason why the wind industry settled on the three bladed, horizontal axis turbine, and it wasn’t aesthetics.
People have been pushing vertical axis turbines for decades and the laws of fluid dynamics keep saying “no.”
The inherent turbulence and upwind travel of the blades lowers the efficiency of these into the teens.
Just stop it.
I could mount one of those on my husbands rear end and power a small town.

I like this design because it could actually be scattered throughout urban areas, whereas there would never be a large traditional wind turbine installed anywhere in a city. Then we'll have two great power options for large scale and small scale

@@neddyladdy In NYC, thanks to the canyon effect of the skyscrapers, we are experiencing much higher winds...
@@Nikosi9 NYC? What is that? do you know if there is much energy available from that wind. I know that the traditional wind turbine wants long runs before and after the turbine. The lack of urban turbines points me to think it is not as good as it appears. I do not have any figures to say one way or another.
AGREE ; Large scale is not very effective and kills way more birds than small scale or VAWT.... Take a look into Flap Turbines. They are a new type of Cycloturbine that is extremely efficient and easy to build. Small Wind is Win Win Wind
yeah, great for integrating into existing development, but there's a reason "traditional" turbines are still the way they are for dedicated high capacity production. the huge radius of the turbine blades is a feature, not a byproduct. it's to catch more energy from the larger area
About fifty years ago a friend showed me the same invention, with an extra boost, provided by a hoop much larger than the diameter of the centerpiece, fixed to receive a wheel attached to an arm fixed on the central axis, and resting on it, driven by the centerpiece, but as it's further from the center, more rotation.
indeed, this is not an invention from this guy, is just another variant from a vertical axis windmill.
That wind turbine has an maximum efficieny of 20% (hard mathematical limit), what means that the overal designs will reach 15%, probably. Currently used WT are at around >45%. So, you cant compete with solar, cause you still have moving parts and necesity for maintenence, and you can´t compete with HWT because this simply can´t meet the efficieny. This will not leave the bus stations...
Solar needs maintenance
@@johnlucas7333 sure it does, I was just high lighting the pros of both techs and why they are used
why not make the blades photovoltaic?
On my afternoon walk today, there was a leaf or piece of debris blowing alongside me. A gentle puff of wind suddenly put it far ahead of me. When I caught up, I noticed it had and unusual shape. I immediately thought it might make a good wind turbine design. My 5 minute search brought me here. This is close to what I saw. All the best designs are already part of nature. Glad to see someone has put this one into production for a wind turbine.
Guess what, you were wrong.
These turbines have been around for decades, they're nothing new and they're very inefficient.
And leaves aren't exactly designed by nature to catch wind???
It is funny how you call "traditional wind turbine" to three-blade horizontal axle turbine, which science and experience has proven to be the most efficient design, i.e. the one that grabs the maximum power from wind. VAWTs always have the same problem: the blades move against the wind as they rotate, and that consumes power. It is so simple to see that I am amazed you are selling it as a revolutionary possibility.
Yes, traditional turbines are huge and this one is small. But those huge turbines produce megawatts, but the Ice Blade could just power a couple of light bulbs.
scale it up, it's not like those traditional turbines don't need ACRES of land to sit on because the rotational space of the blades, right?
the main reason that horizontal axis wind turbines are generally used is that they convert wind to usable electricity more efficiently; when you combine that with the economy of scale and mature designs of the horizontal variant its pretty clear why they're used for most applications.
That depends on how you define the efficiency. Traditional horizontal fans wins out if you only consider the area they occupy. But that may not be the most important factor as the world is huge. What matters more is energy produced compared with cost of installation or service cost. Traditional horizontal fans are so terrible for both that they are almost not worth building. The vertical type shown in this video on the other hand is very cheap, that makes it not only better then the horizontal fans, but also compete better with other alternatives. It doesn't hurt that it's also less noisy and intrusive making it easy to put anywhere.
@@znail4675 the range of wind speeds that thy operate in is greater Traditional horizontal fans need a big separation because of the turbulence they create
Silly narration with EXTREMELY dishonest comparisons between VAWT's and HAWT's as you're comparing multi-mW turbines to dinky 600W VAWT's on the ground! Multiple studies have been performed, by 3rd party engineering companies that show vertical axis turbines producing only a tiny fraction of the energy of horizontal turbines with ROI time frames of: 600+ years. There's nothing new about VAWT's, they've been around for many decades, even like this Icelandic dude's style and they still produce little-to-no energy. I know, I've sold thousands of small wind turbines over the past 15 years and have one in my own backyard, powering my own home, on a 40' pole. Putting ANY wind turbine on the ground will be a guaranteed waste of money as wind turbulence and low-wind speeds will starve the turbine. Don't waste your time and money on dumb ideas, buy cheap solar panels and call it good.
Why is the ROI so low? The wind turbine looks flimsy and does not need much material.
yes, this rather stupid narration forgot so say anything about efficiency
@@chenqin415 Look up Betz's Law, which states that at the maximum you can in theory obtain only up to 60% of the energy contained in a certain area through which air flows, in realistic conditions this number will be lower. As the area is very small for these small turbines and at low altitudes the speed is low, you'll only get tiny amounts of power. For the same amount of money you'll get much more power with solar panels, even at high latitudes. On top of that PV panels last longer and won't require (as much) maintenance, hence the $/kWh is much lower. For large wind turbines however, the wind speeds are much higher, for more hours in the year, in a much larger catchment area. Therefore, wind turbines in the MW scale do have lower $/kWh, even with maintenance cost included.
If small wind turbines could be as cheap, we would see them all over the place already.
@@Soepsliert Well said, the fact already told us the truth
Has anyone figured out how to properly dispose of solar panels after their useful life? How about the tons of batteries that must be used to smooth out the intermittency issue?

@@vaktgunnar They are actually really good. But most verticle turbines are only 20 - 30% efficient, where our big three bladed ones are 40 - 45% So, good on a small scale, not so much for large scale.

Compared to wind turbines which are hitting close to the theoretical caps of 59.6. With 50% being the max cap of current high end turbines. 35-45% being normal...
If we can downsize current turbines, and get the exact same output. That would be great otherwise it's pointless.

This presentation is from the salesman perspective, but I want to have it worked out from the engineer perspective.
Here's my perspective (MSc in Renewable Energy Engineering)
Most of what he claims is true in it's basis, but not accurately depicted. For example: Horizontal axis wind turbine blades are also moved by the pressure differential, like an airplane wind. Also the noise and vibration really isn't an issue, the shadow flicker is. But that only affects areas a few hundred meters around the turbine (depending on location, but it can be easily simulated before construction) also he compares the sound of a 5MW turbine to that of a 500W turbine. Also also, the vertical axis wind turbines he shows are all on ground level. You know what's weakest at ground level? The wind... That's why the comparison again doesn't make sense.
The disadvantages he's talking about like that the turbines will be destroyed when the wind is too strong or the exponential cost, or that the orientation of the turbines are all way WAY overblown. They were problems, then someone came up with a good solution, so now they're not a problem anymore.
The entire video seems to be just an ad for a technology that has been shown to be inferior. It's not like those vertical axis wind turbines don't have any use-cases, but... well I don't know of any, other than where you need a helicopter to access the area. That's where horizontal axis is too heavy.

Actually, not that new of an idea. Similar devices have been made from split oil drums. The rub is that the wind mill is far more efficient. This is why we don't see farms of this type. There isn't much of an escape from high placement of the generator structure, as there is more wind higher up. This structure can be placed somewhat lower, but will still have to be put on top of a pole or tower.
Whether this is feasible for mass power generation depends on the efficiency price paid for going with this set up.
How many kilowatts per acre can this device produce?
I can see putting them on high tension, cell phone and some power poles to feed directly into the grid. I also like the idea of SMR's (small modular reactors) to generate electricity.

Most houses have something like this on their roof for ventilation or something.
It's to keep air temps in attics cooler. Since heat rises, attics are always hotter. But due to thermal equilibrium, the hot attic will warm the cool room below it. The vent acts ass a vacuumed sucking hot air out as apposed to blowing air in.
The threat from fossil has not been known for 15 years. It's been known since the 70s.
Unfortunately these blades are going against the wind half the revolution, do the math.
Yup... thus it's efficiency can goes down.
Honestly I think the best way is to use miniature version of traditional turbines (radius of not more than 2 meters) and place them on each of the buildings that are reasonably tall enough.
People can't grasp that wind energy is unpredictable, insufficient in most areas, utilizes moving parts with limited life times, meaning replacement costs!
I noticed that these wind turbines work low to the ground also. It seems to me that the tower with ONE turbine should be outfitted with at least two turbines and maybe 3 or 4. Plus why cant you build them as tall as a traditional wind turbine with however many you can deploy up the tower like 10 or more? Just asking? Thanks
Yeah, and in my high school science class in 1970 we watched a movie telling us that if we didn't change, the earth would be a burned out cinder by 1990... Uh Huh...
And in that time, green energy production has boomed, helping curb at least some of the fossil fuel use that would have destroyed us by then. We haven't quite reversed the problem, but we've managed to slow it slightly.
I thought we were gonna become a popsicle in the 70s?
Besides... I think the whole idea that a trace gas that comprises roughly 4 one hundredths of one percent of Earth's atmosphere does anything other than feed plants. Concentrations of that same trace gas were as high as 8 one hundredths of one percent in the distant past and the Earth was a lush green paradise by comparison to today. That was way, way before SUVs could join the party, BTW.
Additionally... we don't really know how much mankind contributes to the total trace gas emitted - I've seen lots of BS claiming otherwise, but, It's just that. BS, IMHO. BS that comes from altering data, hardcoding 'desired outcomes' into simulations, and plenty of other well documented deceptions, all to create the "perfect scheme" to separate the public from their money while trampling on their God given rights at the same time.

This idea, while not new has a lot going for it, not least the simplicity of design, the asthetics is better than that of the typical wind turbine. Maintenance should be easier on the vertical shaft wind generators, they could even be set up along suitable boundaries and act as both power generators and windbreaks. It would likely be a good idea to provide them in muted colouring that blend in with the environment. More robust versions could be installed in larger waterways, or in the sea where prevailing, or ever changing currents would power the turbines. The sizes could be larger as long as the foundations holding the turbines match the maximum forces they ever could encounter in a severe storm scenario. Off-cause, it might be easier just to use more smaller turbines rather than more challenging large versions of those turbines. Mass produced the cost of such vertical turbines for use in the air or under water should be competetive, or cheaper than alternate green energy generation methods.!😀💖
cost of vertical wind turbines
Vertical Wind Turbines - Prices & Costs
The purchase prices of vertical wind turbines are usually no lower than horizontal wind turbines. For the entire small wind power market, there are significant differences in prices and specific costs per kilowatt of power depending on the manufacturer and wind turbine model. The price range is between 3,000 and 10,000 euros per kilowatt of installed capacity.
Due to aerodynamic disadvantages, system regulation and storm protection is more complex in vertical wind turbines. For example, horizontal wind turbines can be turned out of the wind as a technically elegant storm protection; this is not possible with vertical wind turbines. A vertical wind turbine therefore requires special technical solutions for system regulation, which is reflected in the construction costs.

Good for small applications; also you don't want to accidentally walk into one of these at night, or have a child put their arm into one. (assuming if mounted at ground level).
Currently industrial wind turbines will generate 1-3MW of power each in ideal situations (typically their only installed in such locations).
To put that in perspective that is 1000-3000kWh, or 1,000,000-3,000,000W, these as per video suggest they can generate up to 5,000W. Obviously this is GREAT for individual homes or small applications and may actually be better then solar in many places with decent wind.
The only way this could be used to supplement a commercial power-grid however is if their installed over a great area on rooftops etc.. (light/power/mobile poles even). The downside however is having to deal with maintenance, mean failure or defect times would be quite critical for such a setup.
Question: What energy/cost would it be to downscale a commercial 3MW one to 3-5kW? because that's the ONLY real way to compare them. Its like comparing a dinghy to a cargo ship.....
Why does everything have to be perfect to be meet your requirements????? Nothing is perfect. Yes it can work for small applications. Yes, it can power a home. So WTF more do you need for it do///// If it works for a house and can be used in 50% of residences think how much that would save for homeowners and the environment. Ease up with the whining. Getting off the power grid would be a major accomplishment for most families. I can use a dinghy. I don't need a cargo ship. Easy to find fault in anything. Just look until you are successful. So what is your solution????
It can be a great technology to use with the wind turbines we use today. To think they should replace the classic mill is crazy, but they can be used in many places as a supplement.
This video doesn't make it obvious that those tiny, slow-spinning turbines near the ground don't have even 1% of the capacity of the giant machines. A nice idea, but they are not equivalent at all.

Vertical axis Wind Turbines (VAWT) have been around for years. This is NOT new technology! However, it is promising in it's smaller design. If the wind can make it spin, it can produce electricity.
You are right. The first VAWT design shown is one of the oldest.
In addition, wind turbines now feather in high winds. It's not such a problem as the presenter suggests.
In addition, the bird issue is a canard that is virtually meaningless for several reasons. First, cats have driven 34 bird species extinct (Mother Jones), second, buildings kill the most birds, third, there are designs and coloring (stripes) that can reduce bird fatalities, and fourth, if renewable energy isn't grown, more birds will be killed by global warming than all windmills combined.
@Mark Twain Your claim is false. Many studies have shown otherwise.
When you consider that burning gas is green tech, well, this makes the gymnastics of green tech quite interesting. The same thing about electric cars, that producess many toxic waste with their 5 year old lifespam batteries...
This is nothing new I saw something similar at least ten years back. They are small because their power generating capacity is tiny. Comparing the two is like comparing a row boat with a cruise liner.
I’ve visited several sites in varying conditions - vertical generators don’t scream.
Wind turbines DON'T produce a lot of noise or vibration, they're very quiet and exceedingly stable... This video is really full of a lot of ridiculous inaccuracies...
vibration is usually from blade delamination and unbalanced props. none of the points in the vid are ridiculous inaccuracies. I have yet to see a windmill incorporate what was used in prop airplanes for decades, blade feathering. a much better idea than having to lock down the prop in high winds.
@@aphilipdent variable pitch blades have been used for years on wind turbines
600Watt = 0,6 kW. We as 300 citizens are building two windmills of 3.850 kW each.
It's a POS scam. Any decent engineer can see that at a glance.
The reason they built the wind mills so tall is because the wind is more stable. This will no change the world only for small scale in my opinion.
I like anything that harnesses the power of nature.
I have a concept design bouncing around my mind I need to get more serious about.
Those traditional look wind titans are so high because the wind is much faster at that height, there seems to be a blind spot in this mini-documentary that doesn't address this.
Years ago my late brother drew a design for a Savonious turbine fashioned from an oil drum, sadly, he never had to opportunity to make one. Since then I have sometimes wondered why this style of turbine has not been adopted. Those who comment here to rubbish this design forget that, being able to place these locally without the problems of conventional turbines, they overcome the enormous cost of transmission lines and sea proof platforms. They can compliment conventional turbines, not replace them.
I built a Savonius turbine about 15 yrs ago and it came out great. I used chimney metal, split lengthwise and mounted on 12" dia acrylic sheet so overall diameter was about 12". It worked great, but then I tried to build the generator part. Not so good at that. So now that I'm retired, will build another turbine - maybe a little bigger - but then just buy the generator and go with that. If I'm really smart, I'll v-log the build and post on U tube.
One reason the large conventional turbines are gigantic is because wind blows more consistently the higher up you go. These are great if you live in a place with consistent winds at ground level, but there are many, many places on the globe without consistent, let alone any wind at ground level. They aren't the silver bullet the poster proposes because of this. Elevating them presents a load of problems not mentioned here.

At least he was woke enough to include a black female engineer. Very important that it not be a white male engineer. You know, something that is way more likely to exist.
Harmony Turbines are the best to date!
I’ve seen a video showing this type of turbine situated on the divider of a highway, activated by the passing traffic.
Seems a way better option than the massive turbines that are so environmentally devastating in their installation and end of life, which I believe is about 18 years, when they are not removed totally but just perhaps the blades. Certainly, the hundreds of tons of concrete and the steel reinforcing that supports the base are there forever.
Great comment.
Trying to recuperate aerodynamical losses of moving traffic instead of simly minimizing them is kinda funny))
I thought of this a few years back, should really just be dialed down to support one household ideally.
The average temp in April has so far been much higher than in March. If this trend continues, the earth will be a molten blob by December.
Nice.
Read up before making claims. The earths temperature has more to do with the sun and Traditional windmills are as a propeller also a spinning wing. By the way. A vertical axis of rotation is structurally much more sound, however the wind load still requires a very heavy foundation. Guy wire systems still have to tie into something heavy.
You do know that the "preverbial frog" was lobotomized before the experiment right? Healthy frog won't sit for you in a pot regardless of it's temperature. :D
Also wasn't boiled in milk
Hence "proverbial"
While some Vertical Axis systems can reach energy efficiency close to those of conventional rotor blade, they suffer in areas that make them untenable commercially, for example the primary reasons a Rotor Blade generator is tall is not because of the blades, though larger blades increase efficiencies, but because of reasons of Mass Air Movement, as there is more energy the farther from the ground effect, this is why Horizontal or conventional Rotor Blade systems function best as large off-shore sea based systems, So even Vertical Axis systems will need to be built high, and this creates issues with servicing the Gearbox, as it is these mechanical issues that increase Vertical Axis operational costs and decrease their life spans. There has been some fascinating research on Vortex Based models but no testing systems have been developed as of yet.
Old Savonius innovation from Finland.
It's 🐝 two years since you uploaded this video and the world has not changed yet my friend 😅
Six-hundred watts = 600 watts not 1600. Quality check your work before publishing it.
I saw an anemometer on the British coast fifty years ago employing this type of blade.
I had seen a discovery documentary on this design ten to twelve years ago and I think this design was first originated and commercialized by a Canadian firm....I may be wrong
Well, the Savonius wind turbine was invented by the Finnish engineer Sigurd Johannes Savonius in 1922. However, Europeans had been experimenting with curved blades on vertical wind turbines for many decades before this. The earliest mention is by the Italian Bishop of Czanad, Fausto Veranzio, who was also an engineer. He wrote in his 1616 book Machinae novae about several vertical axis wind turbines with curved or V-shaped blades.
Unpopular opinion: Man will find a balance between Co2 productions and the consumption of the same. We will figure it all out. We will have our cake and eat it too. Humanity will go on for hundreds of thousands of years on earth.
Where did you get these “Rise in Temperature” stats from?
Out of their butts!
NASA! they’ve been “ reimagining” the historical global temperature records again, which now , coincidentally, show an increasing trend, and also , double coincidence ! , correlate with the recent increasing CO2 measurements . 😂😂😂.
The cult of climate continue at speed to delete and conceal any actual science or data that discredits their “ settled” climate science.
decades of records taken from the top of a giant tropical mountain covered in snow.
@@RIXRADvidz are you thinking CO2 readings from Mauna Loa ?
What if we were embarking upon extraterrestrial beings with a turbine engine😂
They do not produce enough power. Also very expensive for the power produced.
The fix to both these is size, but as he has not fixed the crushed bering issue that is why we have horizontal wind turbines and vertical now it's a red herring
this sounds like a not terribly well camouflaged advert for `Icewind'...
A typical household may need 5-6KWh per day , so given 500W maximum power of wind turbine, 10-12 units would be necessary. Powering the household would be possible only in rural areas, not cities.
Meanwhile, a regular nuclear reactor somewhere in the world created about 1.8 MW while watching this video, 13.000MW per hour, some say they average about 1GW per 24h.
So, how many of these do we need to compensate 1 Gigawatt? Let's average about 1500W for the industrial yeah? Hmm, we need oh that's a funny number... 666.666.
Calc yourself... Divide 1 Giga (1 million) with average watts (1500) = 666 666.6666666667, that's how many you need.
Question is, is it cheaper both environmental and economical to install 666666 of these wind turbines, just to compensate for 1 nuclear reactor??? How many reactors does the states have? Oh 54 of them... So I guess the complete goal to replace all reactors is.... 36 million wind turbines.
Biden is walking in Obama. Obama said that electric prices will "necessarily" have to go up so wind and power will be economical. Also I wanted to build a vertical windmill just for fun. I found that this type of windmill is a fraction as efficient as a horizontal windmill.
Fossil fuels are highly subsidized...
@T Patterson Do you not know what a subsidy is? XD
I would like one of these rather than have solar panels. My roof has too many obstructions, windows for loft rooms, velux roof windows but these would work well on my chimney stacks.
I actually built one of these a few years ago. I'm an idiot, why didn't I patent it.
Because despite what this idiotic video states, this turbine was invented in 1922.
@@NWChickenDad Thanks. I wasn't aware of that.
Helix wind turbines have the least bird strikes, time to make a change.
