I looked this up and it doesn't seem very affordable compared to solar. However, for most areas, you need a permit to have wind installed on a roof, so a silent model would probably be the only option if you want wind. Also it has one big advantage over solar: Ameren (my local utility) has a net metering program tat gets zeroed out once a year which happens to be at the end of summer. This means that even if they owe you money they will just void that and remove any credits you earned from generating power in the summer. This means that you need a system that exceeds your average usage if you want a grid tied system where you don't have to pay the utilities. Wind, however, is more abundant in Autumn right after that reset date so depending on the cost might be better than solar or might work well as a hybrid system. Looking at the numbers: The "Liam F1 Mini Urban" model wind turbine costs around $5,450 + installation costs, goes on the roof, and generates no noise. It's based on the Archimedes screw and is advertised to produce an average of 1500 kwh per year with wind speeds of 5 m/s average, but will produce energy when wind is blowing as low as 2 m/s and nothing below that. This means that the advertised "average" will really depend on how windy your area is on average. Getting an anemometer first would be a good idea to determine what your average will actually be. You can buy one for less than $100, but unless you plan on writing down the numbers multiple times a day every day for a year you are better off spending a bit more on a model that can log historic data. You can then use that data to determine how suitable wind is for you. The average household in my uses 8,376 kwh a year. If we round up and assume you'd want 9,000 kwh and if we also assume each unit gives you an average of 1500 kwh a year you'd need 6 of these for a total cost of $32,700. A house that uses 9000 kwh a year will end up spending an average of $500+ a month so such a system would save $3000 a year meaning it would take 11 years for the system to be paid off assuming no maintainence is required.

[@TheyCalledMeT]

sounds like your utility provider will put the zeroing for wind at mid autumn .. 11years at best for ROI is a bad deal, is there a tax deductible or something you left out? else solar is much better thanx to those

[@larryroop2050]

When I signed up for net metering with Ameren Illinois four years ago, I was given a choice of resetting October 1st or April 1st. To me it made the most sense to go with the April reset date. It has been my experience that having the build up of credit going into winter allows me to supplement natural gas forced air heating with electric quartz heaters. I would like to add a small wind turbine to my solar panels as a safety net to allow additional heater usage should I need to.

[@RichardHarlos]

It's not a mutually exclusive option. If you already have solar, you can install this as an adjunct. When it's bright and sunny, let solar be the primary source of energy. If it's cloudy, or windy overnight, then the turbine fills in what solar cannot do. Why the 'all-or-nothing' mindset?

[@flodjod]

[@Elliandr]

With solar on a grid tied system you usually need to plan for more than your average usage because utilities like to zero out what they owe you at the end of summer right after peak power production. Wind, on the other hand, peaks in Autumn (at least in my area) so you might be able to get away with a smaller system. From what I read each one is supposed to average 1500 kwh a year when the average annual wind speed is 5 m/s. This translates to 11.18 mph which is higher than the average some states receive. Then again, increased height decreases obstacles so increases this average. You'd really need to put a good Anemometer on your roof for a year to know for sure what to expect in your area. This would not only tell you your average wind speed, but also when the wind peaks which you'd need to calculate against your local net metering rules to determine if you need a system larger than your usage. Assuming the listed averages are correct though, 6 of these units would produce an average of 9000 kwh a year at a cost of $32,700 - not including installation and shipping costs. This is actually fairly close to the price of a grid tied solar system. Maybe a bit more expensive, but certainly not 5 times the price unless you live in an area with very little wind. The real problem is that unlike solar systems most areas require a permit to have wind installed. They are more likely to approve a small system that doesn't produce noise which is probably why units like this can be more expensive than what we used to see. Regarding maintaince a solar panel needs to be maintained up to 4 times every year. They have to be cleaned because dust and leaves will reduce their ability to function. Heat also tends to damage them over time leading to gradually decreased returns. Interestingly, wind turbines need just as much maintainance. I guess the advantage here goes so solar though since you could technically just install a PVC pipe to the side of your house, run it to the roof, and have it spray over the panels to clean and cool them whenever you turn on a hose making the typical kind of maintainance in solar easier to plan for whereas wind turbines need to have the oil checked meaning you have to actually go up there onto your roof. So, not more maintainance, just more difficult maintainance.

[@RichardHarlos]

@@Elliandr wrote, _"whereas wind turbines need to have the oil checked meaning you have to actually go up there onto your roof."_ You're talking about those massive 3-bladed industrial turbines, not the archimedes turbine in the video. Of the latter: **Lifespan and warranty** The standard warranty on the turbine is 2 years. At purchase you receive the warranty form. This should be filled in and handed to the producer (or agent / dealer, depending on where you get the warranty) to obtain standard warranty. Additionally, 18 years warranty can be purchased, bringing the total at 20 years. The wind turbine is expected to last 20 years, if properly maintained. You can obtain a maintenance contract / maintenance package at your agent. For more information please contact your agent, they can be found at the website. Despite the design of the wind turbine LIAM F1, which is completely mechanic and contains only two moving parts, these parts will wear over time. The axis of the blade is mounted with two ball bearings, as well as the shaft which makes it possible to “look for the wind”. The wear depends on the number of turns that the parts make. The number of rotations depends on the wind speed. Location of placement is therefore important. Theoretically, the bearings can endure 250,000 to 300,000 operating hours. Assuming 8000 hours per year, the bearings can last approximately 30 years. However, we recommend, depending on the circumstances, to replace the bearings after 10 to 20 years.

[@frustratedalien666]

[@anandawijesinghe6298]

As an engineer with wind turbine design experience, I can say this is false sales hype. The total wind energy input is decided by the maximum area swept by the turbine, it is therefore quite small. As a drag type turbine, its conversion efficiency must necessarily be below the maximum 59% Betz limit, and much smaller than that of a lift driven 3 bladed propellor turbine. The cost of this device will be much more than that of a structurally simpler and lighter 3-bladed propellor. which uses much less construction material. Its mounting immediately above the roof means it essentially has no mast, and that it is not installed high enough above the roof to capture sufficient free unobstructed wind flow. There is no way this device would cost effectively produce sufficient wind energy to justify its cost; it would simply be a white elephant, and a neighborhood eyesore continually pivoting like a weathercock towards the turbulent local wind direction, and not efficiently capturing the kinetic energy of even the turbulent local wind! Don't be misled by this sales hype !🥵 !

[@solarwind907]

Yeah, I would like to see their published power curve for this device. It looks like a rip off. I also wonder how quiet it is. If it’s screwed to your roof, it’s going to transmit sound to you if there’s any sound to transmit. The last time I was in a house that had a little wind turbine on it, it sounded like they had ghosts. And if you’re really unlucky, of course, you’ll have a resonance problem and you will have screws backing their way out of your sheet rock. Well, thank you for your post.

[@MickPsyphon]

@@mikewaterfield3599 To your point about green energy sources, it seems that they're most effective the closer to the equator that you get. Where I live wind and hydro are probably the best sources of green energy, but wind is unreliable at certain times of the year. During the winter, there's plenty of wind; and it can make -25°C feel like -40°C when it's really howling. We get a fair amount of snow. Sometimes I even need to clear the snow from the roof to avoid it causing a collapse from all the weight. No doubt, any wind turbine would need to be cleared of that much snow; and even freezing rain will bring everything to a halt. What I'm wondering is just how difficult it is to maintain these turbines in wintery conditions; and how robust are they?

Despite all these sources of energy we still suffer from rolling brown-outs and power cutting out for less than a minute, every other week.

A wind turbine can only extract energy from the wind that impinges on it's frontal area. And not all the energy that exists in that cross section of wind, at that. Even if this turbine could extract all the energy that impinges on it (It can't) it would be limited by it's frontal area. Add to that that solar panels have no moving parts and are therefore intrinsically longer lasting and it is no contest.

Yep, the next small form factor rooftop mounted scam. Solar is king. Prices are now few times lower than coal per watt installed capacity. On top of that solar panels are almost maintenance free and expected to last at least 25 years without significant degradation in efficiency and very possibly more than twice that. Wind has it's place but only the big commercial wind projects when installed in places that see constant winds in excess of 10m/s. These rooftop mounted flimsy turbines are nothing but a scam luring not very technically savvy people into spending their hard earned cash.

STORE the heat. we keep throwing HEAT SINKS on everything and BLOW THE HEAT AWAY. we call the heat the LOSS when the heat runs EVERYTHING. what does heat do? can cook on heat. heat water. dry clothes. AC works by heating a fluid to cool a fluid... a lightbulb is just a heater driven to luminescence. electricity is convenient, thats all. we have grown accustomed to it. it doesnt mean its the best way to do things, its just easier... in most cases. in just about all cases i think of using electricity... its just heat. motors and a few other things here and there being minor exceptions. storing it as electricity? its stupid. nukes and coal plants run on heat. steam. the bigger the tank, the lower the losses through the walls... lot of energy in water. even more as it changes phase...

[@nunyabidnez2729]

Something found on the web. These things are up there with those water out of thin air devices. It's a drag wind generator with no aerodynamic component increasing generation. This makes it effectively closer to a Savonious than to even a Darrieus turbine, which is to say close to the least effective common form of wind generation used for pumping water and the like. A two- or three-blade horizontal axis wind turbine and most Darrieus-style vertical axis wind turbines get an extra kick from aerodynamic lift, especially the HAWTs. It uses an awful lot of material for the amount it generates. All else being equal, you need to increase your swept area to get more energy from the wind. A two- or three-blade HAWT uses a very small amount of material to increase the swept area because swept area increases by the square when you have a circular swept area with an axis in the middle. This thing looks as if it would increase material required more than the swept area, which means its intrinsically limited to be tiny. There's no way to feather the thing except by turning it 180 degrees to the wind, which only partially reduces the wind load. This means that you can expect it to get blown over in high winds much more regularly than more sensible designs. They are idiots about installation. Their site shows these things mounted directly on rooftops. Anybody with any knowledge of the physics of laminar air flow knows that all else being equal, rooftops are really stupid places to put wind generators because the wind is slow and extremely turbulent there. Putting wind turbines on masts well above surrounding obstacles and in the clearest air possible is the only way to get economic amounts of electricity out unless you build your wind generator from spare parts you have in your shed as a hobby. They go down the path of dissing solar panels -- need maintenance!, don't work in the dark! -- and other types of wind generators -- kill birds! -- instead of publishing standard wind speed to power generation curves which every credible wind generator manufacturer does. And I say this having dug into the spec sheets and scientific papers on their website. This is two anti-patterns for the price of one.

[@fermitupoupon1754]

They do actually publish efficiency curves for the turbines and they do not look good. 3m/s is the cut-in speed. If it's below that either it can't spin the generator or it just doesn't spin it fast enough to generate any sort of usable power. Even on their 1.5m model in order to get the 1500kWh/yr it would need to output 172ish Watt constantly 24/7. In order to generate that 172W it needs a wind speed of around 9m/s. So it needs constant wind of around 5bft or 20mph in order to get that advertised number. In order for it to reach it's rated output it needs wind speeds of 12.5m/s or just over 6bft or 25mph. Oh and it cuts out at 14m/s and self destructs at 35m/s. So it doesn't do anything below 3bft, it won't reach rated output until 6bft, it cuts out at 7bft, and it dies at anything over 11bft. That seems an awfully small window of operation. Oh and they apparently start at 10k euro, not including structural work to the roof, because it needs to withstand 3kN of load during normal operation and probably a lot more during storms.

What's also important here is understanding and thinking well. This isn't being presented as a universal solution. Where solar makes sense, use solar. Where solar is spotty but there's some wind, use both. Where it's cloudy most of the time but wind is present, this makes sense. The video said the turbine operates on *_as little as_* 5m/s, not that it requires an *_average_* of that velocity. And again, it's being presented as the one universal device that everyone, everywhere, at all times, should use exclusively. So, yes, to the video, eyeballs are important. But to the intelligent, they're understood as being important to every video on KZbin, not only this one. So, when you mention something universal as if it's particular, you're either being dishonest, or you simply don't understand why what you've said is 'a difference that makes no difference'. Thinking well is a *_skill._* As such, it can be learned about, practiced, and improved. 10/10 do recommend you look into this option.

30m is a tad high, anything above 80ft in the US needs a red blinky-light.

[@Snowwie88]

This type of energy production (at least here in Western and Northern Europe) is very useful because solar panels do not give enough production during the winter period. And at those long nights you don't have sunshine either and in winter it's often cloudy (windy) weather. There this turbine comes in pretty handy. According to sources the average windspeed on my location here in the North of the Netherlands is about 7.5m/s, so it definitely can help out. When the wind is blowing, especially at night, and the temperature is cold, then turn on the convector heater or even store heat in a type of stone that can store heat for a long time, only when you have excessive power available. That would be ideal. I would love to buy one or two of these, and never have to worry about energy again. Also because in my country 'netting' is being abandoned.

[@janos5555]

The North Sea is definitely a windy location, but I think it is highly unlikely that you can achieve such wind speeds. The usual rule of thumb is 4 m/s for a good location, 5 m/s for a very good location, and 6 m/s for an extraordinary location. If you really thin about it, you should put up a mast and do measurement for at least 1 year.

[@smaragdwolf1]

a good video for a small chuckle. There is a reason why we install bigger an bigger Wind turbines on Land and Sea. A small turbine, low to the ground, thats only usable if a certain wind speed hits it, will not generate much energy. Also... if the neighbor build a new house or a single is in the Way, that alone can change the currents in the area, therefore affecting this small turbine. Today is a typical Day in November.... that turbine wouldnt even work because its less than 5m/s windspeed...... but solarpanels work fine, because they dont need a clear sky.... just light. Plus... the moving parts have to be checked regularly. If its silent, it means the Dynamo inside, that generates the energy, doesnt give much resistance. Low resistance, low energy production. Its not a good comparison but think of the old style dynamos on Bicycles. The faster you are, the more energy it generates... but that also means it gets louder. Its the same principle here. Sure that can be reduced if you use ball-bearings... but that are just more moving parts that can fail. They dont even give technical data beside the size and how much it allegedly generates. A proper advertisement would mention atleast the needed technical data.

[@137bob3d]

good comparison to an old style dynamo, the one on my schwinn bike pressed against the front wheel. and the drag it created could be sensed while pedaling. having a light 'on' was a lot more pedaling effort. given that the spring -force pushing it against the tire was a constant un-changable pressure has me wonder if the drag it caused vs the light energy created was overkill. this all was back in the '50's. some time before re-chargable batt's. later on i changed the lite on my bike to one using c-cells.

Hey everyone, just a quick note, I invite you to check the data : The video says that the Liam F1 (diameter = 1.5m) can produce 1500 kwh/year with wind at 5 m/s, I have serious doubt about it. First let's compute the power of the wind : Pwind = 0.5 * p * a * v^3 With p : density of air (kg/m^3) = 1.225 kg/m^3 A : area of turbine (m^2) = 3.14 * 0.75^2 = 1.76 m^2 v : speed of wind (m/s) = 5 m/s So the power of the wind that will be put in liam F1 will be : Pwind = 135 W = 0.135 kW Number of hours in a year = 365*24 = 8760 hours So the energy of the wind in a year will be : Ewind = 0.135 * 8760 = 1184 kwh Wich is less than the 1500 kwh said in the video. Morover, the wind will not go at 5 m/s 24h/24 (by far), the efficiency of the F1 is not 100% (see Betz limit) and we should have energy loss due to storage, friction or stuff like that. I don't know where these 1500 kwh come from, if my reasoning is wrong, pls correct me, otherwise, it is unprofessional to tell these kind of numbers without quick verifications.

[@MrSummitville]

No, the rated power is at 12 m/s wind speed

[@axe2grind244]

In Hamburg, NY you could put one of these on a house and you could power a small city with the amount of wind we get here. Gusts are “only” peaking at around 40mph today, pretty calm out there.

This is a Northern European design. So I have a 34 KWh solar system with lithium batteries that cost about a third more than the big turbine of 20 KWh output, backed up with a 17 KWh generator.

We live in Andalucía, Spain and get on average 320 days of wall to wall sun. In summer, very little wind so we will stick with our solar panels, thanks.

Not like serious sales, more like scam. To harvest 1500 kWh per year I need 3 standard solar panels where I live. Less in southern europe or the US.

But it is considerable more expensive than solar.

Solar panels as well as wind turbines vary in their ability to produce energy. Solar panels are dependant on the amount of sun that day, and of course, are useless at night. Wind Turbines are dependent on the wind. No wind, no energy production, Low wind, low energy production, high wind, max energy production, and unlike solar panels, works also at night. IMO, using both wind and solar should result in a more efficient system for producing energy.

[@Kristian-sj8bn]

Seems difficult to find a seller/installer and there's no original site. Also the 1.5m one seems only to produce 1000w which is not much at all compared to the 5500 USD cost I found.

[@yvesinformel221]

1kw and they claim it can produce 4X the power of solar panel, all you need is 2.5 panels, of course it does not procude anything at night (so put 5 panels), but wind does not blow all the time either (except in some places and I would not want to live there).

[@garygough3158]

They are depending on people not doing the math. If you divide the total kwh by the year in hours you get an output of 171 watts at the average wind speed. So with the average modern house using 1000 watts ( also on average ) it would take 6 of these to power one house. Also need storage to handle peak loads and calm winds, a microwave oven alone would take the full output from 6 and add a toaster and you are drawing from batteries.

What if we decide to combine mini residential wind turbines with solar??? Then we can produce renewable energy all throughout the day. Just a suggestion!

[@Lea_Kaderova]

Of course you can (and you far wouldnt be first with such system). Problem of these wind turbines is incoherent power output, as it can change from maximum to almost none in single minute, or even shorter time. Its problem for fotovoltaic too, but in branch of wind turbines, its a much bigger issue as intensity of wind is more random and changing more rapidly than sunshine. In other words, if you want wind turbine with more serious power output, you will have to somehow store energy harvested, because management of power grid will not allow you to let into grid those random peaks and voids of electricity. So with wind turbine since certain power otuput, you will need also own battery storage, which depend on batteries type cost quite a lot money (at least as much as turbine itself, but probably more), or clutch off turbine generator from turbine itself = you will not produce electricity quite often to cut off those power surges = your investition will not produce value quite often. There are also other approaches to solving of this problem. Some people store energy in form of small pump water dams (when they harvesting more electricity than its their actuall consumption, their system automatically start water pump which pumping water into higher water reservoir and once they need more energy than their micropowerplant producing, they start small water generator feed from water from that reservoir to produce more electricity). But again for such solution you need space for water reservoir, mechanization (water pump/water turbine, electric generator etc.), quite a lot of electronics and money = more investitions. Other approach is to store energy of that unstable power source as wind turbine in some flywheel, in form of kinetic energy, but its too complicated and expensive for ordinary people, same as that water dam before. Unfortunately, there are reasons why wind turbines arent so widespread as renewable energy source between people as fotovoltaic and this is it. It start to be economicaly reasonable only in much bigger dimensions (wind power parks etc.). I personaly think, it would be much better to adjust this type of turbine for water and developed some mini generator for small creeks. Such streams have also iregularities in their flow, but incomparable smaller than wind flows, so that need of complex and expensive solution of storaging of energy would fall off.

[@mattj8937]

One of the major issues with renewables is displayed so clearly in this video, companies are racing to to be the top and they'll never tell you about the options of integrating multiple renewable systems.

On days of clouds interfering with solar power, weather patterns without sufficient winds also effect the efficiency of energy production. Every power source has its strengths and weaknesses in the process. By utilizing the best multiple sources available for your particular area, is it possible to offset consumption from the grid power. Install wind and solar energy together as a hybrid system. Or solar and hydro power systems together. Just don’t depend on one source of energy such as the utility grid. They also can fail at any time.

[@dscott1524]

No, this will not replace solar cells. There is a minimum wind velocity. I tried a wind turbine near the ocean with a on shore breeze, but it failed. Mine only needed 2.5 m/s wind velocity. Couldn't get that reliably, was intermittent at best. Except for special locations, there is just not enough energy in the wind. Get a anemometer and check your wind speed before buying into this. Most likely you won't make the 5 m/s minimum. It's a very stiff breeze. Cheers.

Based on typical wind speeds, the output from these wind turbines might only be about 1/3 the maximum power. Also, they cut out when wind exceeds certain speeds when they could be generating even more power. The cost for these is also ridiculously high since you would need a rooftop full of these to replace a rooftop of solar panels. It looks like the price could be around $1K-1.5K or less if mass produced. Of course, wind turbine efficiency would decrease as more units are placed closer together, and there isn't that much room on a roof, and most urban houses are on relatively small plots of land.

For example, the government was giving a good tax incentive to get solar panels, but the solar companies (I figured out) were calculating that into their open market pricing structure.. at the end of the day that corporation would end up with the profit, and the government incentive tax money, while the homeowner still gets his tax rebate the following year, not calculating the artificially increased pricing structure because the homeowner expects a rebate.. if we want Green to succeed, one thing we need are government regulations to enforce fair pricing for installs.
