that is a nice thing to say mate - cheers
Too bad we have smart everything today except smart governments. Too bad the United Management Body Of Planet Earth still doesn't exist. What a dystopian ineptness.
They'd ruin it somehow ... 😂🤣
Robert, about those bearings. If someone is trying to build this from scratch the bearing size that you used is a 6005 (47 x 25). If buying one new you should specify 6005-2RS which is a sealed deep groove bearing. Deep groove bearings are better able to handle the axial loads created by gravity with the rotor oriented vertically. The 6005-2RS has an axial load rating of better than 300kg, which is more than enough for this application. Very well done!
Its not gravity, Is just that materials with densely packed particles are heavy depending on the element some dense structures are heavier than others. And it just so happens that most things are heavier than air. Due to denstiy.
Yes, there is a bit of weight in that thing. The bearings he has is fine for testing, but for long term use it would be better to go with your suggestion. If built in metal it will be a lot heavier and if you put some weight in it for a flywheel it will be a lot heavier. Thanks for pointing that out Mark.
thank you for posting that mate - that is really helpful - to be honest if I bought the bearings I might go for some more suitable for this job - I am just using what I found and trying to moderate it for using it in this orientation - I think you are right they will do just fine given what I am doing with them and the load on them but it would certainly be better if they had a conical design
@@EnterTheRealm strictly speaking the weight of an object is defined as an objects mass multiplied by the gravitational constant, which in our case on earth is around 9.81 ms^-2. Density is a measure of mass per volume and is not used in the measurement of an objects weight.
@@michaelpearson5465 strictly speaking the gravitational constant is non existent. The force doesn't exist so nullifies what you have said. In only works in theoretical maths. In reality its just density.
The weak point will be the blades. You would do well, to place a spacer in the middle of every blade, attaching one blade to another. Then, you will have an official "squirrel cage", just like in many HVAC units.
lack of elementary knowledge in this video is painful. 9% efficiency's for drag type VAWT is max. Check how much energy 1m2 can give you at 20m/s wind speed. it's disinformation. if it is honest it's just thick
That spins great in the car park! This, so far, is the best-looking VAWT I have seen yet. All good wishes!
1:20 he threw the turbine by hand and let it spin, it's not the wind that spins it
I'm a retired electronics engineering technician going to try building a vertical wind turbine generator that is a little different, I've had this idea for about 15 years I just haven't done it yet. It's time to turn a drawing into the real thing. Not connecting the turbine to a generator but turning the turbine into the generator with no belts, or shafts. I'll probably make it out of wood, and fiberglass in resin and use bronze bushings with neodymium magnets on a shaft for bearings. I figure there are blade angles that work the best so I'm watching videos and learning before doing it myself. I like to use wood because I can cut and fill wires and magnets inside and after fiberglassing it's super strong and can take good g force, also I have done this construction skill before building robots, test equipment, and hot rods. I plan on using magnetic sensors maybe Hall effect and some kind of digital speed controller that will turn on and off power resistors for braking. The magnetic field on the turbine created by the resistor load will slow it down in high winds. I would like to find an already-built module for speed control but if I can't find anything I'll use open-source robotics software that can run on something low-powered like a Raspberry Pi. just have to get something small working. I think using robotics software I can use part of the circuit as a brake while using the other parts to generate at the same time if the batteries need it. Also, anyone like hobbyists or students can rewrite apps or subroutines for it.
nice...but the design would be lucky to get over 200 Watts . simply the cross section facing the wind is too small for 1kw. Unless it was a tornado.
I think a Horse could kick it to bits..... thats at 750 watts 1 Horsepower.
Love your works. Always promoting your channel. :o)
to be honest mate I am just going by the power curve on a representative 1 kw commercial turbine - I need a wind speed meter really and I plan on seeing how it does in various wind speeds and doing a comparison - you are quite right I think it will need 25-30mph wind to have a chance at 1 kW - but so do commercial wind turbines of fan blade design - so we will see - maybe it will fly apart - that will be fun lol - cheers
I love how you used the bottoms of hydraulic office chairs to stabilize the turbine. A+
Agreed.
funny think to work so well lol
God has said in the Quran:
{ O mankind, worship your Lord, who created you and those before you, that you may become righteous - ( 2:21 )
[He] who made for you the earth a bed [spread out] and the sky a ceiling and sent down from the sky, rain and brought forth thereby fruits as provision for you. So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 )
And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 )
But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 )
And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 )

By my calculations even if it cost £200 and you got 500W for no more than 8 hours a day it would pay for itself in a year.
So have you measured the torque? Speed is fine, but TORQUE is a vital necessity in wind generation devices. A small suggestion; If you made the blades much bigger, and blocked the wind from the up-wind side, you would create lots more torque. The blocking wall would turn with the direction the wind blew, so the wind could not blow the blades backwards, and rob you of torque.
Nicely diplomatic Jack.
Otherwise what a humongous waste of time and resource for what will be a truly puny output;
It has **far** too many blades for a start. It will work as a wind blocking device - you **have** to let the wind blow through the thing. It would make an epic fan though, as per what's buried in the dash of most cars.
So why not just use 3 blades, a little more plastic for a tail and use the bearings so it can follow the wind.
Thus using a fraction of the materials, a fraction of the time to build, an off-the-shelf motor as its dynamo, much greater reliability and get 10 times more electricity out of it
Just come across your channel love the project I have subscribed looking forward to you testing it in the wind it's should do pretty well by the looks of your test. I need to go and watch the other episodes thanks for sharing.
new content idea- "wind turbine ASMR" LOL. that things spins so smooth its quite calming
lol
The shaft needs to be supported on both sides with a rigid mechanical bonding, yet most of these turbines wear out over a few years because the frame should have springs to permit some flexibility. I would also add shock absorbers to eliminate chatter or extremes. Without full frame flexibility, the unit wears all in the exact same places and simply fails an early life. Good luck.
I tried it but it doesn't give you enough torque to move an alternator on high speed 😐😐
Great stuff. 'Love it Rob.
-One question: are you considering magnets and coils only on the bottom or both bottom and top?
just on the bottom
@@ThinkingandTinkering it would be awesome on both !!
That reminds me of Joe 90. 🎶🎶
Great videos, going to try do the same using bicycle wheels for the top and bottom. Thanks for inspiration keep it up.
how did your wind turbine turn out?
Just a question with it. Could you mount magnets on top and bottom and change mount structure to double the output? I would like to build something like this but I would need accurate and complete list of things involved
Magnets itswlfs would just act as a flywhell but when you would add coils it would generate resistance and i doubt efficiency would be good much better to make transmission from the shaft onto the generator
Seems like too much mass for that low of an rpm. That's good for maintaining rpm. But only in high gusts.
If you want some actual power from that. It should be 4 times as tall. And three times as wide. And your blades could be a little bit closer together.
That's what you want for the amount of weight you already have.
Then you'll get some real thrust to wait action. You could even put a smaller gear on it for a higher ratio to the generator.
I believe that u could design a generator that could power a home for a grand or two do u ? Make it quite powerful and self supporting, no need to be on the power gread and ur make billions
Love the VAWT, I would wager you'll get about 250 to 400 watts out of it based on size and number of blades but, it will be cool either way. Hopefully you can reach the RPM needed.
to be honest mate I am just going by the power curve on a representative 1 kw commercial turbine - I need a wind speed meter really and I plan on seeing how it does in various wind speeds and doing a comparison - you are quite right I think it will need 25-30mph wind to have a chance at 1 kW - but so do commercial wind turbines of fan blade design - so we will see - maybe it will fly apart - that will be fun lol
I love the construction but 1000 Watts seems a bit optimistic. Any update on accurate figures?
I was wondering about the same thing... so did a bit of estilations: Assuming a wind speed of 10m/s, air density of 1,16kg/m3, rotor efficiency of 30% (optimistic for sure) and cross sectional area of 1 square meter, that would produce 174 watts of power. Double the windspeed for quarduple power, half for quarter power etc. That's just the rotational power, rest depends on the electronics.
It seems the blades should be on a "collective" similar to helicopter blades, where the angle grabs the wind for up to 270* of rotation, and "feathers" thru the other 90*
This would require lots of rods attached to an offset crankpin, and LOTS of little bearings on the blades.
Interesting. How much noise will this produce cmpared to a horisontal three-blade turbine? Noise is usually the biggest issu for place a windturbine. I'm ging to build a new garage and placing a system of vertikal windturbines would absolutely be somthing I would be considering. Needs a double roof to protekt the windturbindes from snow. Also placement of a radial windturbine into a venturi could be interesting to try. We almost always have wind, but combining several small turbines with a battery solution...
Look up water studios Parthenon.
I had thought of that with about 20 foot vertical wind turbines forming the top portion (and 30 foot wave turbines underneath), with slotted recurve wave walls and slotted rock armor that would stagger out for more or less a mile like a spider web rice patty with each ring about 5 feet lower than the previous, that would greatly reduce large waves before it even got to the 20 foot wall, all the while generating power from water, wind, and solar on top of each portion of the vertical wind turbine top ring.
I thought it would be made out of graphene concrete and graphene plastic or carbon fiber or steel. Each ring would be about the width of a 2, 4, or 8 lane highway.
The inner circle would have relatively calm water, and the air “should” be calmer. You can have a more central proportion that would close like a Huge stadium roof (hurricanes)
What I’m Really curious is how it would fair in Really Rough Seas like a Hurricane.
I thought of the interior, and exterior you could grow algae for oil in bags like kelp. That way you could grow oil, you would have all renewables as your Wall, and you could generate hydrogen and transport it to the mainland. Besides having a floating city in the middle where everyone could live and work, and you could have floating hotels for people to visit and see everything up close in comfort
Brilliant video thank you 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍 brilliant man
I have been watching a lot of wind turbine videos. My question is if you mount the turbine with a tail so it will rotate. If you block off 1/2 the blades that would cause drag on the system would it not this turbine to work better. I am thinking sort of like a water wheel.
this is a brilliant idear, but to big to be usefull for house hold. what about in a closed housing with low opening on Roof line. so the Rotation isn´t visible from the ground, also kill the sound of the unit.
Now attach it to a D Drive (australian) invention. Have you seen the windmillsof Iran, fantastic bits of kit. You should be able to get 5kva.
Whats a windmill of iran? Any links to go read?
cheers mate
got good bons success there family
With a 1KW turbine like that how long would it take to make 8KWh (the average daily use in UK 3bed house)?
Vertical Axis is the superior design over conventional horizontal axis wind generators.
This is totally pointless. Most of the time there will be no useful output and it will never pay for itself. For starters the great majority of people liv e in areas where the mean wind speed is not particularly high. The power output is proportional to the cube of the wind speed. Next this thing is not very big. The power output is proportional to the square of the linear dimensions. That is why, to be worthwhile, wind turbines have to be big and in windy places. Anyone taken in by this will be very disappointed.
I could see 3d printing small bracket/receivers for the blade end mounts, slow, but good repetitive work for the printer.
Just rewatched this brilliant btw was thinking would your serpentine coil and magnets on the bottom edge of turbine work.
I do realise the amount of wire would be huge and a massive pain to make. Thanks
ha, ha ze vraj 1KW. Odhadujem max 10W pri rychlosti vetra 30km/h
Im sorry but vawt such are yiurs are known to be weak in torque. This is because half of it is not facing the wind. With rrspect to the other half facing the wind 25% of that is oppposing the other 25% percent. This is because the left and right side of that other half facing the wind are being pushed in opposite directions. Its not only low cost that matters but efficiency. There is not much future for this kind if turbine.
If hell doesn't break out in America because of the election chaos then I will be waiting for part three of this amazing series.
Hoping for the best.
yes I have been watching the results come in!
This is almost as exciting as project Binky. . . But moving along much more quickly.
how many episodes has that got up to now?
@@ThinkingandTinkering - I think the last one was episode 32 and the first one was 7 yrs ago. No rush guys :)
Looking forward to seeing your turbine generating power Rob . . .
Hey Robert I seen you making wind turbines at like squirrel cages and stuff have you ever seen them a Bird gone or shiny things they put on people's roofs and stuff they look like a wind turbine it spins but it's shiny so it reflects in the birds Don't go near it have you ever tried to make a wind turbine out one of them want the wind gets going they they do pretty good so check them out you're good at building all kinds of stuff like I've been watching your channel for a little bit now about a year or so pretty interesting keep it up stay safe and have fun
HEY,
make a big one of those using the new bi-facial solar panels as your blades.
Are you sure you're not an identical twin to Anthony Hopkins
maybe not with something that big, but i'm wondering if you have the vertical squirl cage design if you could have a top and bottom magnet bearing. or how about a magnet bearing using 3 magnets with the center one mounted to the rotor with the top magnet could attract up to carry more load or maye repel down for stabilithy ---- then have a set top and bottom.
These designs were found to be highly inefficient. That's why no one wants to build them. While you have spinning motion, the leading edge always creates drag on the system and wastes the momentum.
I was wondering if stronger magnets like industrial graded magnets would yeild more power or make the whole set up more unstable?
Walmart sells electric leaf blowers $30! Make your own wind!
Hi Mr Robert Murray-Smith. Where can I mail you a vid of my project?
Beautiful Bernard
Thank you! Cheers!
@@ThinkingandTinkering Morning Rob Imagine How That Would Look With Red , Green And Blue LED's Spinning @ High Speed

Fake idea not building
it's only testing 👎
I'm getting dizzy watching the chair base spin round, and round, and round, and round,and round! Well you get the picture!
Looks very functional Robert; how stable do you think it will be in high winds?
lol - I find it hypnotic mate
I wonder if you placed a wing inside and kept it orientated in direction of the wind if you could control how the air flows over the blades
@Robert Murray-Smith >>> 👍👍
I wish I could get an idea of the dimensions: the diameter and the height of the assembly
yıllar önce bir Türk'ün böyle bir projesi vardı. Ondan mı esinlendin yoksa çaldın mı ?
Certain washing machines have axial flux motors built in. They also have SUBSTANTIAL mounting/bearing bosses with meaty, beefy bearings as standard, designed to take VERY high radial inertial loads ... A 9kg load spinning at 1200 rpm ... Is a LOT of inertial load!
The biggest problems you are likely to face are:
1. Finding a suitable direct drive washer, nowhere near as common as standard universal motor. Look for good German makes.
2. Being able to dismantle & cut the outer drum away sufficiently but keeping sufficient material to use as a mounting. Alternatively, cutting the hub away completely from the outer drum is often an option.
3. If the washer is scrap due to worn or seized bearings then the biggest issue is gaining sufficient access to be able to remove BOTH inner and outer bearings and replace them with new. It's doable with the right tools and technique but often it takes a LONG time due to greasy gunk, gunge, rust, and all round general filth especially around the bearing water seals - yuck!
Even if not used for this kind of project it's worth it to just get at the direct drive motor (used as an alternator) and removing the hub completely to work at on the bench and used for any project having to handle large radial and moderate axial loads.
Access to a decent sized lathe gives MUCH flexibility in altering the diameter of the bearing seats in the hub to take different style bearings, like even beefier or larger bearings. Originals may be a non standard size so changing bearing seats can give access to much cheaper, more easily obtained bearings from Ali Express (great low cost source, albeit slow to get ... 2-6 weeks).
From personal experience I'd say ALWAYS use xxxx-RS or -2RS (RS = rubber sealed) and not -ZZ (steel sealed) as they are well worth the miniscule difference in price (pennies) and the slightly less operational efficiency due to the rubber sealing friction but MUCH longer life in dusty/damp/external environments (VAWT).
I've pulled apart many washers and tumble driers (good source of reversible synchronous motors!) and it's not just the motor that's of value:
Lots of useful parts like temp sensors, heating element, general flex wire, heavy duty springs, tube sealing spring clips, vibration dampers, switches, water valves, relays, triacs, thyristors, other electronic components.
But the biggest, often ignored pieces are the large area enamelled/galvanised FLAT steel panels easily cut out with a steel cutting disk on an angle grinder - brilliant for all sorts of things like magnetic white boards (!!), Cutting further, bending into custom size steel project boxes & enclosures, creating other structural pieces, large sheet galvanised side up tops to protect your work bench top when doing metalwork. The list is almost endless.
Telling you those hover board motors are cheap.
Please excuse my ignorance, but can the voltage (inverted) just go to the grid (using a meter)? I couldn't go the work of storing and using the power, so can't I just sell it to the National Grid (if I built a big one...or four)?
The alignment of the sides could be adjusted with metal wire under tension. Similar to bike wheel spokes.
nice idea mate - cheers
Another bird mincer. Useless when the wind stops.
You are amazing sir... am your new student.
ridiculous !! read betz's law
What happens if you turn it such that the main shaft is horizontal?
How is this going to be used in the space where there is no AIR?
I am a old wood worker
So your chop saw m8
Can cut perfect circles !
Sink the saw into large bench , i use a hatch and drop suported below so when not in use easy to remove !
Position saw and work peice , large circles saw at 45
Use a screw in center of circle to spin the work peice and start choping , you will get to a point where you hold the saw down and finely trim perfect circles, shure you can fill in the gaps of my explanation, your not daft!! , you can use the setup to index very accurately as well and so on , like drilling or edge details ect
Have you considered using magnetic bearings to float the rotor
yes mate
@@ThinkingandTinkering does this have them?
wow it nearly produces 7 Watts I'm impressed . He should work for Nicola
Good luck with your project. Renewable energy rules!
cheers mate and it does indeed
VERY COOL!!!!! i wonder if the efficiency would be boosted by having one on top of the other spinning opposite directions coils on one and magnets on the other, or alternating on both.
yeah probably
I think you'd get the same power generation benefit from just making a single one twice as tall without the added complication?
@@popuptoaster the reason i think a second one going the other way, is that it would increase the speed at which the magnets and the coils passed each other. doubling the height would infact double the torque (theoretical), but reversing the top one would double the speed as well, without any actually penalty to torque (also theoretical, as it would increase the drag created by the magnets passing the coils)
@@ravenbishop2557 You'd have the same amount of wind hitting the same amount of blade area with one twice as tall as with two the same size so you could either use the increased torque to add more magnets and coils which would have the effect of speeding up the pulses or you could put twice the load on the existing magnets without stalling the turbine.
Maybe it's more efficient your way and to spin less magnets faster I don't know, but i suspect that, long term having twice the amount of bearings and effectively twice the maintenance requirements would even things out. You could also spin the magnets faster by increasing the diameter of the turbine without adding the complexity of an extra one spinning in reverse.
One of the main arguments for solar over wind is the increased maintenance, noise and vibration that comes with wind generation so you'd be wanting to minimise that as much as possible I would think.
@@ravenbishop2557 I'm not poo pooing your idea, just thinking about it from a KISS point of view.
Looking even better now it's vertical. Looking forward to seeing what it can generate.
Please be careful it doesn't take off and chop someone's head off! ;-)
I was thinking of making the blades from sharpened steel just incase it did fly apart but then I realised I was being mean lol
I want to learn this concept. This is amazing. Do you have any reference for the same. Please do the needful.
HOPE WE CAN SEE INSIDE THE POWER POD WIND GENERATOR
Have you ever thought of a small one for vans
у меня есть разработка лучшая
Sir... Do not use bearings, use permanent magnets and let it hoover with almost no fricktion.
Cool. Looks like one I designed a while back. I levitated it on neo magnets and put alternator on top.
U should check out my little video on my channel.
Could see these mounted on lamp posts.
Nice video. Although, given the swept area and a relatively inefficient collector I don't see it producing 1kW at any reasonable wind velocity.
Hello Robert, can you give information about noise levels? It's important in a urban area to have this in consideration in my opinion. Thank you for all your sharing of knowledge. Not just on this project, on all your videos. Thank you!
I don't know right now. mate - but I guess I will see
@@ThinkingandTinkering Thank you!
I did not see a single electron move!
I wonder if a partial shroud to shield the negative side of the turbine would work, could us a wind vane to keep it oriented for changing winds.
Very good if 100W
It spins so easily, and keeps running a while I expect this to be a total success and will likely generate more than your target. Love it! 🌎✊🏽🌻✌🏽
Fingers crossed!
Hi Robert, I keep wondering whether it might be better to cut curved slots in the discs to house the ends of the blades. The blades could then be glued into the discs
He seems to err towards simplicity. There's a lot of opportunity to make an errant cut with what you suggested, even though it would be more sturdy. If you have the skills$equipment, go for it. Just pay attention to detail
poluliach blia.
1kw ??????? wer
Could have cut grooves into the disc and slide the blades onto them, ring on outside to keep them from flying out
I wonder if you could get that cost down by using a slow speed generator, using a big wheel to mount arms on it. At the end of each arm would be mounted a giant bamboo half to catch the wind like a cup. And you could have a few of these mounted on the wheel for a vertical wind turbine. While using air scoops to speed it up or that funnels air to the wind turbine. ?
Will you sell it?
The real problem is that there are not 1000W, you have 50-60W, sorry...
yep might well be - I will certainly see
How easy is it for this kind of wind turbine to runaway in high wind ? Like when the big ones spin fast enough to rip themselves apart.
@Chet Carson i mean yes I am ignorant about this kind of thing. That's why I ask.
@Chet Carson i don't mean this specific wind turbine. I mean the vertical style that he's making commercial or home built. Intuitively it looks to have a self limiting factor due to the blades.
Sir's question is quite relevant, even if materials don't cost much. Thinking intuitively, this design is quite self limiting so spinning too fast will not be a problem. Freakish winds bending the blades might be but the construction seems pretty solid, more now when he reinforces the connections of blades. Some long bolts from top to bottom around the outher side of the inner body could do the trick?
@Chet Carson I think your are missing my question. Its not about what its made of. Its the design of the blades. Presume that it was indescribable, and we had an infinitely fast wind speed for this hypothetical, would by the nature of the blade design the wind turbine self limit the maximum rpm the it could obtain .
@Chet Carson You DO seem to miss his question. Does the design of the turbine allow over-revving and thus making it break?
Love it, cant wait to see part 3. Keep it up!
cheers mate
either you are a classic cheater or you are crazy
You can only get 1KW with it in the center of the hurricane
What a BS. Lower efficiency than the horizontal axis and what wind speed it gets 1kW at? During a hurricane?
Show how it spins when it is loaded.
If it spins at all.
You are happy that it’s spinning freely?! What an accomplishment! Wow!
that seems a very mean comment and really not very well thought out - any 1kW commercial wind turbine needs 25-20mph winds -and did you watch the other vids? or just figure one was enough? ah well -it takes all sorts - cheers
Robert Murray-Smith I’m in the business of wind turbines. Also invented the most efficient VAWT yet.
It does not change the fact that they are BS.
Just a few places on the planet that they make sense where average annual wind speed is 8 m/s or higher.
What everyone fails to tell the overly enthusiastic iPhone kids is that the rated power of a turbine is given at 10 m/s. In most places the average is not even 5 m/s. And that when wind speed drops down by half, turbine output drops down not half by 5 times!
To 1/8 of its rated power (2x2x2=8).
Yes, it is a cube, not proportional.
No matter what wind turbine it is, they are all BS. Especially the VAWT. There is not much energy in the wind. End of the story.
I have seen only one honest company that actually showed what happens when a 1kW turbine is loaded by a 100W light bulb at a moderate wind speed. Just one hundred W load and the turbine practically came to a stop. So did the sales of that company.
Cannot defy laws of physics.
sir,is it worth more energy efficient than electricity generated from solar panel ?
Use a smaller radius on the wheel for the magnets. This adds torque for the magnets to pass the coils. Looks good though. Looks very balanced.
to be honest mate - I am astounded about how well it is balanced and quite honestly this has nothing to do with me - I just stuck the chair legs on the pipe and it worked!
How much this turbine can generate and at what wind velocity?
I used to love watching the Christmas lectures as a boy you make every show just as interesting and fun thx Robert...
Lots of room for improvement with little cost. Like old Muslim windmills, cover the half that is returning against the wind with holes to allow the air pressure out on the sides, then on the other side have a bit of plywood or something sticking out to the left channeling more air into the active bit of your windmill, like a funnel is for water and it will spin faster with more torque. IF you want it faster for longer, use ceramic bearings as well, they are brilliant but not cheap. You can store excess in super capacitors and lithium batteries, then when the wind dies down, you're good to go.
1kw=wild claim. I doubt it. I work in they wind industry. Too many claims around hobbyists. I respect the work but make no claim in until proven please.
fair point mate and I agree with what you are saying
a high speed motor could turn that faster and make even more energy using a beat truck alternator. with just one 775 and a solar panel and one e bike battery i can make using a 40 amps alternator (self excited) then transformer for a 120 volts 20 amps high speed 3hp motor to turn 4 beat truck alternators (which totally works) (self excited so you only have to install energy when starting up). then you have 1400 amps plus some volts that mean 700 amps worth of 120 volts and 20 amps. which is 5 per hundred and 7 x 5 is 35 120 volts and 20 amps wall socket and that is just a under an apartments worth with 17 plugs plus one. that is the two per wall type. the only hard part is the huge wire transformer to turn 1400 amps into 700 amps 4200 volts.
240 volts for the win..
