I saw a while back a type of wind turbine that was small and omni-directional. I have not seen any follow-ups since. Could you see what you could find out about them and where the tech is now? Great video and this was a sponsor I could get behind....
I'm an aerospace engineer with an interest in energy systems at the moment.
I have been trying to tell people that some of these types of alternative wind technologies like Vertical Axis Wind Turbines (VAWTS) will have applications in future and in particular on the tops of houses, apartment blocks and office towers where Horizontal Turbines (HAWTS) just don't work. Either they are to noisy (propeller noise) or their mountings are structurally incompatible with mounting on a rooftop.
Yes without doubt big 3 bladed HAWTS have the efficiency when they are out in the open country side, perched on top of large posts with suitable footings, BUT you can't put them in your backyard or on your roof.
I'm in Australia and we have 1000s and 1000s of homes with solar in places with good reliable wind, especially in coastal regions because they get incredibly reliable sea breezes. Plus Australia's sea breezes are driven by the sun but they are operate on the opposite side of the solar cycle. They start to blow in the afternoon and then blow consistently through to the next morning and drop when the sun starts heating things back up.
So in certain locations the solar inverters (right now) are only pumping out power when the sun is up. If those systems are fitted with a small *COMPATIBLE* wind units those systems go from pumping out power during daylight hours to *ALMOST* being able to generate power 24/7.
So I think these guys are being very smart. They aren't trying to solve to overall energy problem but instead they are trying to fill a gap that's there.
the carbon cost of the unit is surely much lower than conventional turbines as well, less maintenance and a much longer projected life with easier maintenance has to be factored in.
@@kevinwillis6707 Great point! I haven't seen any life cycle assessments on it, but I bet that is true.
@@ZirothTech saw a report where they stated that because the moving parts were inside, they could be in the roofspace or even at ground level, and not subject to weather, the projected lifespan was essentially indefinate, compared to a 25 yr span for conventional wind turbines.
If you shape a whole building or skyscraper using the same principle... probably that could generate a lot of power?!
Now there is an idea 💡 🤔
Agree, there are several building sites in downtown Los Angeles where a wind tunnel effect has been inadvertently created. At times you can barely walk at street level.
Could potentially also provide HVAC airflow, reducing power consumption.
@@williamlloyd3769 Got any examples for reading and curiosity? Interested to see what they look like.
It would in Chicago-if a majority of wind there goes at one direction! 😒🥶 A different angle would be less efficient.
Been here since your first video. I'm so glad to see how much this channel has grown and the continual quality content. Cheers!
Thank you! It is truly appreciated :D
I remember an episode of a show called "That's Incredible" where a Japanese building had its 11th floor emptied and it's glass removed to stop 60 MPH gusts of wind at its base. I have since then wondered about using wind shear to power turbines.
Bladed systems are SHIT for building turbines... But imahine a building designed to capture sheer from 4 directions and a solar facade and rooftop
I remember that show.
I would be super interested in this type of company setting up on beaches. Most beaches have some sort of structures on them. Where I live, NYC, the beaches have large, raised toilet blocks at regular intervals. There tends to be constant wind at those sites as well. Would be interesting to see how this tech works in such an environment.
I mean it could be even better at offshore platforms but the issue there would the elevation
Thank you for a clear description and analysis.
I keep getting ads for the "Harmony" wind turbine which looks interesting as it can fold in on itself to protect itself from very high speed winds but still generate some power tucked in and expands its sails in low speed winds to grab more air. Doesn't seem to produce more than about 400watts for one unit but it's a nice concept.
This is off of the top of my head at the end of watching this, so I have not considered engineering loads, etc. This may be a useful application mounting this horizontally on High Rise buildings in cities to take advantage of the updraft created by solar heating of the glass and building. In combination with newer solar window films, some city buildings may be able to become self powered or even have a surplus depending on conditions and all of the engineering I have neglected to this point.
My solar is quite good for 3/4 of the year. There is lots of wind in winter and shoulder seasons and it would be nice to have a supplement especially as our electrical needs will go up with the eventual installation of a heat pump, replacing natural gas. Not much makes sense yet at small scale. Hoping for a breakthrough that will change that.
This would also surely work at night? I've seen this elsewhere and it appears you can have this even if you've already got solar panels on your roof
It means having less batteries too, which is kinda cool. Efficiency is nice though it's cost per W that matter to most
@@waqasahmed939 Yes I am waiting for specs to come out for some of these ideas. I have a property large enough for a small turbine, but not sure how the neighbours would react. A more discreet design with guaranteed low bird impacts would be great. We live along a river with lots of hawks, eagles, geese, ducks. The list goes on.
@@leroyharder4491 Aeromine doesnt use moving blades. No bird impact
@@cuzz63 I know, lets hope it proves to be an option
I am glad he pointed out the most important factor in wind power -- the wind speed at the site of installation. Unless you live in a very windy area, forget about wind power by any means.
Naw don't forget about it... you just have to stick a super tall pole 80 feet in the air and take site measures for two or three years to know what you are dealing with. Wind can be great but needs to be looked at as site specific and getting your wind measurements perhaps viewed more like getting your land surveyed (albeit a much longer timeframe). Just one man's opinion.
I would like to see smaller versions of the same thing, so that by being less burden on the roof, and being able to spread their weight and directional orientation, flexibility would be gained. Production costs might increase, but so would volume of sales and use. They might also be utilised for ventilation.
this is the smallest look at the fan itself from the bottom it is not possible to give such energy
@Truth Balm He's useless, he's not even good for that.
I'd think the maximum survivable wind would be more of an issue than the loss of efficency when the wind is blowing the "wrong" way. A hurricane often blows from a different direction to the prevailing wind and there would be a LOT of oscilating sideways force on those aerofoils once the AoA is such that the wing is stalled. If I was making them I'd think about easily replaceable blowout panels to deal with that.
@@arrell1xyz The TURBINE does but the guide vanes are fixed.
smaller versions of these would be amazing to run in addition to my solar system, hope to see it in the future
You'd be doing well to sub to the Robert Murray-Smith channel. The man's a goldmine of very useful projects and information.
Whoa very informative, always wondered about these 👍
Glad you found it useful!
Great video! How does this turbine compare to leading competitors in the micro-turbine market, in terms of efficiency and market acceptance?
I've seen this design doing the rounds for while now and whilst I used to get excited by new wind turbines whether vertical or horizontal or 'bladeless' like this, it becomes clear that wind is a tricky thing to deal with - solar on the other hand is more accessible in that you know what you're getting provided there's no shading or obstructions - the amount of radiation may change from day to day and location but it's tried, tested and "solid state" so no maintenance - I often think new products are introduced to market on the basis that the company will have ongoing income through maintenance contracts - sounds cynical but every "small" turbine I've seen on the market that then appears in real life ends up shelved after some years nowhere to be seen again apart from the odd early adopters...
Small wind turbines are genuinely at a disadvantage compared to the large ones.
@@garethbaus5471 If you simply look at the energy of wind carried over a typical rooftop, you'll never get a lot of power from these things even in strong winds, and if they were 100% efficient. This thing would have to be very very cheap to make sense economically.
@@kaasmeester5903 Yes.
What I find so strange is that they compare solar power to wind power. Those are two different recourses. And often when one of them has a lot of energy to harvest the other one is hasn’t that much energy in it. So you would need both to have more reliable coverage…
And by the way when we compare wind to wind.
The biggest turbines generate with one spin (6seconds) around 20kWh, here in the Netherlands the Eva rage Dutch household uses 7,5kWh for a whole day.
So one spin (6sec) of the turbine can power two households for 24hours😮
@@marekdg I suspect the marketing teams were struggling to find any tangible benefits over traditional ‘big’ turbines so they took their aim at solar as a means of a selling point 🙄 I have had PV up for 10 years now and not had to do any maintenance, okay it’s annoying when there is little or no sun (like now) but instead I have invested into a community wind turbine array of 8MWp which pays me back for the portion I have invested in (1kW) - it’s not my ‘own’ juice being generated locally but it makes more sense to have a bigger, efficient turbine sat in a nice consistently windy location rather than shoving something smaller and likely ineffective into a not so windy location 🤷♂️
Thanks very much . Very much. From Shiraz. Iran.
Super informative and a cool technology!
Thanks Lois!
sounds like a theranos start up
Well done!
I saw a scientific publication indicating that there are still eddy currents of wind within the system that need to be studied to improve the Aeromine design. I would be interested in trying it when that happens because my house, on the shores of Lake Huron, stands three stories tall on a 40 foot bluff. I have built two platforms for windtowers, but just need to select them and try them out when the technology is mature.
Nice video, thanks :)
Interesting... Good to try out in my place.
*How does this video not have more views???*
*How does this channel not have more subscribers???*
It would still be great to have supplemental source of, let's say, 2kW of wind to roof-top solar. Just the fact that it can produce some energy in the night, when you normally only use grid or battery, would be great. But having rotating turbine on the roof is a problem... So even with 4.2m/s winds inside the city, the aesthetics of the thing would still overrule the efficiency, I guess.
I would say the idea needs refining. You could introduce a motor to rotate the blade system into the prevalent wind direction to deal with places where the wind could come from different sectors (maybe two models, one fixed, one movable). The thing looks terribly ugly particularly the bottom part with the turbine. Perhaps for domestic pitched roofs the thing could be designed so the turbine part fitted into the roof space? You might also get some advantage from the roof pitch if the wind was coming across the ridge line. The other issue with it in the domestic situation might be noise. Will the turbine make a lot of noise and transfer that noise into the building structure? The designers will also need to be careful small birds cannot get into the system through the vent holes in the blade and also maybe wasps trying to build a nest.
Apart from ugly it sounds like a good idea.
I don't think we can allow the aesthetic aspects to get in the way of clean energy. It's a luxury we can no longer afford. We have to work with what we have now and keep our fingers crossed for the future.
@@kr1886 Well, agree, but if you can make it look better by hiding the base part with the turbine you get a win, win. You might even consider if a roof can be designed to use the same principle to generate power. Could include solar as well.
Solar is a non-moving system… wind turbines though need to move to generate current so it makes sense to place the solar on the homes and mount the turbines on towers AWAY from other buildings.
Consider what the company is not telling us. They are not telling us the actual long-term average power we can expect to get from a unit in a particular installation. Given its size, it is not going to produce much power. People are not going to go through all the installation and maintenance ado for minimal return. Indeed, it will produce some energy at night, but not a reliable supply. Energy storage is still required.
Here's a silly make-believe extreme example: A company offers, at no cost to me, to install turbine-generators in the bottoms of my rain gutter downspouts to produce power when it rains. Wow - free energy! If my roof is 3000 square feet, and if my downspouts have 10 feet drop, and if I get 40 inches of rain per year, and if the turbine-generator system has 60% efficiency, I will receive about 1.4 kilowatt-hours of electricity in a year. (I'll spare readers the calculations.) At the rate I currently pay to my electric company, that is worth about 17 cents per year to me. Would I let the company do it? No.
thanks so much for useful video, very nice system we can use also in country side in Turkey.
There is one particular problem about putting it on top of buildings, if you put this on top of a house often times it's going to act like a sail and capture some of the wind giving it a little push. the problem could come about if the roof of the house is not reinforced to take this extra pressure, it could cause it to slowly over time degrade the structure of the roof or cause a failure bringing the roof down either on the building or pushed to the side
This is a great point, thanks for commenting it! I wonder what would be the best way to solve this - either highly reinforced roofs (sounds expensive) or some kind of pitching/retracting of the aerofoils to reduce drag when the wind is too strong 🤔
@@ZirothTech There are ways of doing it to where you can reinforce the overall structure to make it fit the problem is, if the house is a older house like what you might see in europe, you might not have all that much room or all that much capability to reinforce the roof for what would be needed
Honestly it might do better that instead of going vertical like what they originally going with, they could do a horizontal type of way which would make it shorter but in theory use left of the strain on the building, also there is a little of fact that if wind hits a structure like let's say for example a rock wall, the wind could actually be stronger than it would be if it was just in open-air because the structure would be pushing more wind in a particular direction
@@ZirothTech it's just the thing about new technology, we adapt our lives and environment to it. it's a natural process. what we must be careful of is the power of money from big oil manipulating things.
CORRECT, IF ROOF NOT DESIGNED FOR THESE WIND GENERATORS, PLACE THEM ON THEIR OWN STANDS OR POLES.
your videos are very good!
even the sponsor is interesting xD
Good job
Nice innovation wind turbines.
Small wind turbines just don't make sense... Sad but true.
Insane is the correct assessment.
Mega interesting vid, thanks a lot for sharing!!!
Good job keep it up
Hi Thank you for the elaborated video, do you have any idea of how the Aeromine is going to be connected to the home where utility is already available. I've searched on the net but I could not find any. Thanks!
Thanks for the video. Interesting. No bird shedding. No throwing kilo ice blocks. I like it You'd think they could have rotate for best wind direction.
Very informative...
Sounds like a good idea. How have the accommodated for vibration and noise?
The one shown on the roof seems to work a little different, with the rounded divider between the airfoils and the turbine visible beneath. The divider may cause an extra low pressure behind it, sucking up air from the bottom, making the turbine spin.
This thing is basically a Dyson fan run in reverse.
Good spot!
Awesome video!
Thanks Joris!
Do you think this can decrease electric car prices and battery need if we brought back radiator openings on the grill and we install one there that could charge the car as it drives?
Soooo, why is it not automatically redirected based upon wind direction? I also believe that a series of circular cowlings would have higher efficiency per square inch than a two sided airfoil.
2:50 the long winded shpeal on steel was an unecessary detour from the issue that really matters, which is the design of the windmill per se. If you keep these postings as concise as possible, they drive the point through more efficiently.
I believe that was the sponsor of the video so he was obligated to add that *spiel as you say. 🤔🤔
Really interesting and a great balanced assessment. It seems clear massive turbines work in open windswept places, but we should remain open to research into other micro level applications that might integrate with infrastructure and land in use. As a real estate agent might say, it's about location, location, location. Perhaps on the roof edge of the right apartment or industrial building, or who knows even on a cargo ship, these could offer better energy density, low cost power at point of use when the sun doesn't shine. I can see these working alongside highways with the right prevailing winds, potentially integrated with lighting posts. In Australia where I am they might even produce power for EV charging stations and communities in remote off-grid locations. We even have an EV charging station on a remote highway that runs off used fryer oil from the roadhouse!
Great idea, and this made me ponder if this effect could be used on sail masts. It would introduce drag, but it might be possible to engineer it so there is a good enough balance between energy gain and drag to be worth it.
Windy West Texas is perfect for something like this.
It would need to be steerable over on the east coast as our wind directions tend to be either SW or NE 180deg apart.
czcams.com/video/otQszp_LK4c/video.html would be much better
Tijeras Canyon east of Albuquerque would be the Ideal place to use these guys. There were fairly reliable daily winds that would be channeled east through the canyons. Especially during the winter and spring seasons.
great successful research coming to the actual truth...-thanks
Served 18 months in Iceland at Naval Air Station Keflavik. An interesting field test of the Aeromine would be on the island as solar panels aren’t viable at high latitudes. If the unit survives the gales and weather in Iceland, it will survive anywhere. Faroe Islands or Jan Mayen island maybe a better test site as sites don’t have access to other renewal energy like hydroelectric or geothermal power. Another benefit of this system is that it doesn’t have as much of a visual impact on the landscape as giant wind turbines.
PS - Wind blows morning, noon and night at Keflavik, Iceland
PS2- good video but you should cut the excursion into green steel
Thanks for your comment! This sounds like an ideal use case for this, I imagine it would fair well in extreme weather due to the lack of moving parts.
Should also look at the Halcium Power Pod which is a similar idea but has no issue with different wind directions. Not yet on the market however.
Isolated houses in steppes or coast, or isolated high buildings (when there is a good ammount of wind from ONLY 1 predominant direction, that is, the tropic falling wind of the equatorial climatic cell did not move north and south of the location with the seassons)
I have a wind turbine from MO wind and solar just a 12 volt 1500 watt and it helped
keep the battery power up at night.
A worthy and clever Idea using Bernoulli effect . Needs some development .
A weathervane controlling a Rotary Baseplate would fix the Directionality issue .
Great video sir
The place where i live, usually wind blows for Max about 3 months n it is a costal area.
Remaining period not much wind but in the afternoon after 2pm a small breeze of air there that's all
So is it a viable option to keep such type of windmill here n a viable cost option sir. If so what will b the breakthrough period on getting back the capital.amount on windmill set up sir. Please reply
Thanks n regards
it makes sense on a boat, might be cool to have a few of these on a sailboat
Great content. What about maintenance costs due to sand/dust sucked into turbines?
Weigh that in, and cost efficiency compared to PV will even drop further
That's only a concern in certain parts of the world, and actually the same costs, also for solar.
In the Sahara, Panels have to be cleaned from sand regular.
In Europe, in relativly humid conditions, that's not a topic at all. Rain is cleaning panels, Storm is blowing free turbines.
These devices look very promising, but mainly if consitions are met: on big office buildings, and warehouses. There are plenty of these around! Also, they can be comnied with solar panels. I also wonder if a rotation mechanism would make them much more expensive? And are they more efficient when scaled up like traditional wind turbines?
I have built a sectrometer that included a central pillar that provided a robust central angle of rotation. The first neutron spectrometers were built using WW2 technology for rotating turrents for battleships (the shielding is that heavy). Adding a single degree of rotation would be a challenge on a rooftop. You need a central pillar, with a height that would be sufficient to keep the unit from tipping over. I'm sure it can be done, but the cost of doing it reliabely could add considerabely to the cost of a unit.
I contacted aeromine a few weeks ago with a query on pricing , availability etc, but have received no feedback. i have a 12 kW solar system but would love a small wind system to supplement on dull days
It isn’t abvious the way how it works?
Can you explain the lines of air and what are the matters that respond to air stream?
Is it by friction of air?
Or by the spinner fan under the device as shown in the video?
I didn't know that this was a thing, It's genius.
This is fenomenal...but what have you something good for no-high factory sheds?
Good analysis. In most cases it would be better to build big wind farms with big efficient wind turbines than small scattered inefficient turbines on individual roofs.
Thanks for your comment, completely agree!
Depending on cost a small, inefficient turbine for a homeowner could give them ownership and potential savings vs sticking with the power company and paying whatever they charge for their "clean energy."
This so often crops up on energy generation discussions - why not do both? Most green energy is cooperative, not competitive.
@@LabGecko There is finite pot of money. So we should be making strategies which give us the quickest route to net zero with our current pool of resources. Sure you could tax more to make that pot slightly bigger, and borrow to make it bigger still. But the pot is still finite! So we need to be strategic.
@@patrickdegenaar9495 With the premise that a finite budget exists, sure, I agree. But I don't agree with the premise. We're dealing with completely unrelated budgets - city, state, nation, home, all can afford to build on different parts of the grid projects.
To fix the wind direction issue it could be equipped with a rotation mechanism and some sort of wind sensor. The rotation motor needn't be fast or powerful, so no significant amount of energy will be diverted.
Well, what will cost something like that, for a house? Any websites where I can find some examples?
Might be a terrific resource on top of tall buildings. Cities do 'though often produce a heat dome that shelters them.
Greetings from LooseNatural farm in Andalusia.
I like the ridge blade at the moment. Can u do review on it. ? ✌
As I've stated elsewhere they need to be scaled down so as not to be an eyesore in an urban landscape and possibly attract the ire of the local council who could ban them. Perhaps they could also rotate on a near friction free base ie redirect some of the airflow so as to create a hovercraft effect so it can catch the wind & rotate at all angles optimising the wind flow at all times. If the wind dies down it could still have a low friction ball bearing base on which to rotate.
Does anybody know what is the source of the cost comparison graph presented at minute 7:20?
I'm having trouble finding a good reason why the design can't be adapted to cope with different wind directions. Sure it will provide some challenges, but the solutions that I can think of are significantly easier than what they've already achieved. Any insight?
Excellent unbiased reporting of this company and it technology. I came across SSAB on another video. Both companies are worth investing some spare change in if one likes to gamble in the "Wall Street Casino". The odds are better here than in the Las Vegas casinos.
So what would happen is you raised the up on a pole like the wind turbines?
I am not college educated. But I have a question about the use of hybrid electric/diesel trains and if their use would be a possibility? Is it possible to run a train on diesel in one direction, while charging a battery bank with energy gathered from some of your style wind generators to a bank of batteries and then using only the generated battery energy to return to the next destination? All while sending the energy from the turbines mounted on top of the train back to recharge the batteries while returning? Thank you.
2:48 "reduces the steel needed for construction"
So what are they using? im guessing 110% recyclable fibre glass then
Depends where you are, in australia solar is going very, very well for a lot cheaper than any alternative. The only thing we need here to get to 100% renewables is lots of LiFePo4 battery storage.
I favour residential wind generation. My case is on the basis for available materials and reduced reliance on complex production chains. There's a lot of very good resources arguing that both material and also production capacity used to create PV panels is very limited for the forecast demand. Even simple things like glass fabrication is limited. I think local materials can be maximised especially if using recycled plastics ensuring minimal waste post life.
the bit about the straw sucking up the fluid. you don't suck anything up. you create a vacuum in you mouth and atmospheric pressure on the surface of your drink forces the fluid up the straw.
This is 100% venturi effect and more akin to a carburetor than someone drinking through a straw. 👍
Might be incredibly powerful energy production in Australia, where you could literally have that (strong consistent winds in some regions) and solar on houses and let houses feed the grid...
Why not just invest in large wind Turbine farms, they produce enough energy in 6 secs to power entire households
@@Skorcch Because... and get this... You need to transport the energy. Wind Turbine Farms have a huge environmental, ecological impact as well as their CO2 cost in production. Their primary use is close to agricultural facilities on farms (or best use) where emissions can potentially be off-set with smart farming. Decentralised power is always superior for residential power requirementals and reduces grid surges. Most solutions to energy and multi-layered and have multiple different types of energy.
@@TimBarnesPolygonPerformance Oh I actually didn't know about the environmental impact, I mean it is never paid much attention here in India cause like its less than burning fossil fuels so govt have happily invest in wind farms
To me, I think what is important is having a cheap way of installing renewables, whether that be solar or wind and low price for buying of that, for personal use.
Consumers are much more likely to push this renewable revolution over governments if the cost of installing and the price point of buying is cheap enough to do, whereas governments keep dragging their feet with the fossil industry lobbying them to slow down the adoption, consumers don't have that issue because they will do what's in their interest to lower cost.
This is why for me, having a low-cost installation could do wonders for the industry, at the moment, it's too expensive and complicated which puts a lot of us off, even thought the cost of solar isn't that expensive now and is getting cheaper, the installation cost and complexity is a mess for most, sort those problems out and the adoption rate would likely skyrocket and consumers are much harder for the fossil industry to lobby against.
The icing on the cake will come about with improvements to battery tech so we can store weeks or even months of energy per household.
As for this wind tech, even if it doesn't generate as much energy as they say, does it really matter if it can be done cheap enough for consumers to use? Mixing things up with solar and wind could be quite useful for many, especially as solar doesn't generate energy at night where wind can.
Still, we need more information on this tech in real world use cases but it does look like the tech shows promise and could be made better to take advantage of wind from all directions.
What about installing those in the median of highways. Lots if wind there
Silly question but when you want to grow trees what gas do you use?
In connection with steel manufacture, you should also look at the Australian developed Hazer process which converts methane into hydrogen and graphite, with no CO2 emissions
This could be applicable to street lights and large highway sign supports. Manufacture the supports using this principle along roadways and highways the captured energy can be directed back into the grid. Instead of trying to utilize a small number of large generators, utilize a large number of small generators.
I wonder if there is a maximum wind speed that it withstands and also if it works with wind gusts as well as constant wind. Greetings from Patagonia!
I wish to know whenever it will be up for sale
I love the idea of doing a live steam where we can interact and ask questions, however why wait until Dec. 19? Why not just wait a few days?
Glad you like the idea! The plan is to do it about a week after the upload normally, but I am on an extended buisness trip with work for a few weeks, so unfortunately it is quite delayed this time!
Hello from where we can purchase as distributor for mea region
Good technology viw
open source for humanity
Can you please do a talk on the ridgeblade. 👊
Can’t say I love the idea of a massive thing like that on the roof of my house. Maybe 1/3 of the size and combined with solar. It would have to be silent though. Otherwise I’d be better off buying a few extra solar panels and batteries.
Can they not design telescopic fin wind tunnel deflectors to channel the wind when it blows from a neutral direction?
It's a reverse Dyson, genius idea.
So... What if you replaced the fan on the win turbine with toroidal fan?
I think they are on to a winner here, with a few updates you can see this being very useful.
What they need to do is miniaturise it and sell it as garden kits so it can be played with by people who like to experiment.
But I have seen something similar years ago on a TV program but they did not use the wind for generating power.
The fact that it is ancient tech means it will work it just needs adapting in the right way.
If they made a miniature kit it would make it possible to explore ideas, until they do this it will be out of the reach of most people unless they make their own version.
Solar's Achilles Heel is clouds, which often are accompanied by windiness. Providing power when solar cannot, like at night, makes it complementary. But only if a turbine can deal with non-laminar flow...
They should implement this concept to a vehicles. While the car is moving, turbines generates energy from the movement.
This Does not work like intended. The generated energy would be produced by the car. The engine would have to work harder for the same speed.
Ideally you would need 1kWh of fuel in addition to generate 1kWh of electricity, but there are a lot of losses, so it would be worse.
Sry for bad english, not a native speaker
sir how rooftop wind motionless work show graphic vedio please some time turbine below and other in air pipe attach that concept please clear
Company says not for houses. For commercial properties? Together with solar could be really good. But needs to be able to swivel to catch wind from any direction?
It’s weird, but in sunny Spain/Canary islands there are almost no solar roofs
