I think that I see the potential for another scrapped bicycle project.

nice!

[@petevenuti7355]

I've seen a vertical turbine made from two bicycle wheels connected by slats from some old blinds with something like a magneto on the rim, made out of garbage for free.

[@ryanjamesloyd6733]

That was super cool. You are just Such an educational treasure. The Things you do are fun and interesting, but your explanation of how you think and why, and how you bring us all along on this Journey of invention with care and delight is simply invaluable.

If RMS was attached to a university, he would have been inaugurated as a professor. His outputs alone warrants such an accolade. Even though he is self deprecating, his theoretical knowledge, his teaching ability & erudition is phenomenal. I would venture he puts out more than many academics publish. Thank you Sir for wonderful ideas, practical concepts and background knowledge. Well done. 😊

[@ThinkingandTinkering]

wow - cheers mate and bless you

[@emel60]

I genuinely believe you're changing the world! I don't even read the feel-good, positive news anymore, I just go to your channel and feel good.

[@ThinkingandTinkering]

oh wow - cheers mate

[@hrothgeirrH]

I really like this take on a modular design. On a larger scale you can set each cog pair on a post to drive a generator. When you need to expand and some more chain, a few flaps and another post. When a generator breaks down you don't lose the whole system.

[@pedjamilosavljevic6235]

Actually (depending on available wind and engaged surface area of "sails/blades" , you can put a brackets for multiple cogs and generators . That , also , can be done with more "classic" designs of wind turbines. This can easily be put on incline/hill (doesn't have to be flat ground). Though , it is a pretty complex setup and the maintenance can be more demanding than in the classic setup (more greasing , wearing of the more components , how to deal with cable/chain material behavior on different temperatures , etc...).

[@hrothgeirrH]

@@pedjamilosavljevic6235 I wonder if the option to deploy the solution on a slope or varied terrain drove the choice to use cable instead of chain.

[@pedjamilosavljevic6235]

@@hrothgeirrH I believe it was more of price concern (maybe weight concern - I don't know is there a much of difference) , because one can adjust the angle of the cogs , on multiple points to be in the same plane . Presumably , the blades would be vertical , therefore, mounted at some angle (not right angle) in relation to the chain (or cable) , but that depends on the "attack angle" of the wind stream .

[@salimufari]

​​@@hrothgeirrH slope is one thing that challenges this particular concept. The operation really wants to be in one flat plane & horizontal minimizes gravity wanting to twist the drive system. The torque on any system through those redirects would induce a lot of stress & friction. Even aircraft cable has inherent twist depending on the tension relative to the lay of the wire.

[@spikeccx]

Still need the frame...the chain would fall off ...chain also no good over distance horizontal

[@stefanplozza3411]

After your 2113 video it was clear that one had to expect a follow up - and here it is! Fascinating... I know a bit about computers but never was in engineering. I found your channel some weeks ago when zipping through VouTube looking for alternative energy production and I was fascinatited by you phantasy, logic and skills. Absolutely great channel!

[@ThinkingandTinkering]

oh wow - cheers mate

[@edjones3410]

Great to see such creativity! it might be more efficient with one supporting track in the middle like the aero loop rather than one at the top and bottom as less friction. Would love to see these around the tops of buildings!

[@ThinkingandTinkering]

i agree mate

[@lancealderman2755]

Look out below 😅

[@user-ih3se7nj6r]

Between this and Undecided’s video, I’m excited to see where this type of design leads. Certainly won’t be the best choice in all or even most situations, but seems like it could work exceedingly well in certain geographies. I hope several companies get ready to compete for this market. Maybe some ski lift building companies or engineers can join in.

[@jimbobarooney2861]

The Air Loom is similar to the Madaras Project proposed back in the 1930s. A large circular tract filled with carriages end to end. On each carriage stood a magnus/flettner rotor, each rotor was proposed to be about 80 feet tall and 22 feet in diameter. To maintain propulsion the rotors rotation would need to be reversed on the leeward portion of the tract. Power was abstracted from a dynamo fitted to each carriage

[@cosmicseekin]

Great simplification of a great concept. In real life the uprights/pylons/pillars at each corner could be solid inset in the ground. From there the blades can be on parallel ropes between the pivots at each upright. So, there could be anywhere upwards of 3 uprights and each upright would be a generator point driven by the wings strung between the parallel ropes. If the wings were carefully pivoted a small slave or flying wing could pitch the generating wings to follow perfectly the wind direction to trap the most lift/power from each wing as it moves round the path of the ropes. So the wings would automatically pitch themselves to maximum power generation as the ropes run round their pathways. The final refinement would be magnetic bearings at the generator vertical pylons that guide the rope round any corners. Thus, the maximum thrust will come from every wing all the time and no friction would lose power at the turning pylons/pillars. This completely removes any disadvantage a VAWT has except possibly height above the ground. That would be the design I thought of years ago.

[@danedmiston9673]

I agree. The concept is great for large scale operation with long straight power runs and short 180 degree turn around runs, but would only work well when the wind is blowing perpendicular to the long straight runs. To maintain the optimum angle of attack the "wings" would look like high performance gliders turned sideways. The wing airfoils would be symmetrical like most large scale VAWTs. The most efficient symmetrical airfoils have a lift to drag ratio of about 80 to 1. HAWT non-symmetrical airfoils, have lift to drag ratios between (100 to 1) and (140 to 1) along most of the blade. My feeling is that the "AirLoom" type system cost of construction and maintenance would greatly exceed the costs of today's HAWTs for the same amount of power production.

[@TheMarcusrobbins]

This design appeared in my imagination the other day - nice to see it's already a thing! One more idea I don't have to pursue :)

[@ThinkingandTinkering]

you should pursue it mate - my ideas and your ideas are bound to be different

[@TheMarcusrobbins]

@@ThinkingandTinkering Thanks :) I'm too busy trying to make a savonius using fabric pulled tight to form the blades.

[@industrialmonk]

If you use a bicycle wheel with the blades and magnets turning inside a slightly bigger bicycle rim with a serpentine coil you would have a very nice wind generator.

[@justtinkering6713]

If you remember way back in physics class about levers. Generation at the rim is at the end of the lever. There is more speed but less torque available. At the axis there is more torque and less speed available. Six of one , a half dozen of the other. The more current you pull from the generator, the more mechanical resistance there will be at the rim . It really comes down to how you design the generator. I've come to conclusion after playing with these things for the last ten years that. A very large, slow wind turbine is the way to go, at least at ground level. There is way less wear on the components. You can gear up the speed of the generator with a CVT. Also generation at the rim requires much more magnets and coils. Pretty expensive

[@lonnieschreiner5879]

Wow your 3D printers have been busy. Amazed too see this model video pop up so quickly after the first one on the subject. Actually seeing your model I tend to think that a horizontal setup would the better overall option not only in power production but in structure design and equipment maint. as well. Thank you for shedding more light on this concept.

[@kadmow]

- a new take on the "power wall - the whole wall (rainscreen) moves and generates.

[@ThinkingandTinkering]

i like the idea of a horizontal version mate

[@8ank3r]

Man, that looked like it would never work. When it started building speed, I was like WOW! Great stuff Rob

[@ThinkingandTinkering]

cheers mate

[@Nobe_Oddy]

I didn't think it would move so smoothly, very impressive! When you brought up it being no different if it were turning horizontally from vertically I would expect gravity to play a major part once it was scaled up (and of course as a small prototype too, but not nearly as much) I would also think that putting the chain around a circular frame instead of a square frame would me a LOT more efficient too. Those are fairly obvious to see that they are more efficient, but I can't tell if using a generator on the outside would have a difference between using one gear connected to the top chain and using both chains connected to one generator with a rotor that passes all the way through the generator body and a gear on each end..... That just not something that seem intuitive to me.. which version would produce more power? And that's just like you were saying about building a model/prototype compared to just working it all out in the mind. And that is why I love watching your videos... you actually take the time to build it and not just just assume that you can work out the answers on your own. :)

[@danielbuckman2727]

Thank you, I have gained an understanding of An unnecessary transfer of energy taking place. One day I plan on building a wind turbine for my house. I'll keep this in mind. The large commercial wind turbines all have this problem. They transfer high speed low tork at the wing tips to low speed high tork at the center. Then they use a transmission to convert it back doubling their losses.

[@recumbentrocks2929]

Very interesting as usual Rob. Personally I think there are too many friction points on this generator that will all contribute to lowering it's efficiency. But it does open doors to other ideas which is what tinkering is all about.

[@user-gs6lp9ko1c]

I was thinking that too. Four axles with frictional loss vs one. But, how does the friction scale with size? May not matter when you build a full size system. Completely agree with you and Rob about tinkering with it.

[@richardclark5112]

Yeah, imagine the amount of torque you could achieve if this same model were extended to be meters in length! @@user-gs6lp9ko1c

[@ThinkingandTinkering]

exactly mate! I think you are the first person to have got that and said it!

[@richardclark5112]

Thank You Robert! …Quite some years back I had vision of this type of idea after watching the Americas Cup and also maybe the land speed attempt team NZ made. The vision was perhaps a bit crazy but it was to have fences across farm land utilising this concept running small land yachts attached together running on a rail… Dreams are free eh! I really appreciate your endless energy and effort making these things into a form of reality! @@ThinkingandTinkering

[@Berkana]

I keep hearing "heirloom" and the thought of an heirloom turbine just seems amusing.

[@ThinkingandTinkering]

lol - i keep hearing that too mate

[@dinosaur0073]

Thank you, Robert. In my area, we have little wind but a lot of sun 🌞. So I'm more into solar power for little power for my farm... Thanks 😊

[@trygvetveit4747]

Holy s..t!!! This solves a lot of my problems!!! Love your videos alvays make my day better!!! This morning i met with a close freind who owns a warehose selling tools and other, i told him of your Loom video and asked if something like this could be tested on his building... as it will serve as a wind wall also (40m X 110m building 15m tall on a open plane, in a windy place by the cost) Now im just going to find 600m lightweight chain (and do some 3D printing.. LOL) He said he is in and will supply eqipement to install a test system if i get the design. this is before i saw this video! Btw, he is a engineer also!

[@trygvetveit4747]

Forgot to ask: will it work like this wit a "building" in the middle?

[@ravenmad9225]

It should work with a building in the middle. Not sure where you live,but here in the UK doing what you suggest would mean a lot of red tape. Planning permission,safety inspectors etc.

[@ThinkingandTinkering]

that is awesome mate - yes it should work with a building 'in the middle'

[@maxvaessen]

Haha, nice one! Thanks as always ❤

[@user-hf3ym7lh4d]

That worked remarkably well! Thanks for sharing. Maybe a chain tensioner on the next version?

[@tonyiliffe8907]

It would appear that the chain tends to flex outwards when spinning so is, in effect, self tensioning. An additional tensioner would simply absorb energy and be counterproductive. Excellent video!

[@user-hf3ym7lh4d]

The energy to keep it flexed outwards as well as the energy for all the flapping around it's obviously doing is not free. All you gain by excluding tensioners is premature wear and a bunch of racket. The decreased rigidity will also reduce kinetic energy transfer between the driving and driven parts of the system when you put load on it.

[@ThinkingandTinkering]

for sure mate

[@sylviekoenig9960]

Love it. Love your energy and your enthusiasm! ❤

[@lorenedailey8691]

Think horse walker with several booms attached to a center post. Instead of horses underneath the booms you place wind catchers on top of the ends of the booms, instant leverage. --- With planetary gearing, I'm gearing up a large magnetic rotor with the matching serpentine coils. --- I'm using a large back yard trampoline on stilts to help support the booms that rotate around the trampoline's metal hoop which I'm using as a rail for the rollers that are attached to the booms. That's what I'm working on. I actually think I will be able to move the system by hand when there is no wind. Don't worry I have that trampoline securely attached to the ground.

[@levon9999]

Robert, thank you for sharing, wish your show was available to more viewers, consider making children's educational toys, it would open their minds to the wisdom of thought!

[@ThinkingandTinkering]

it is quite a task to create and market toys mate

[@mattw7949]

I love your content. I do find it funny that the algorithm thinks that if we are here watching science, we must also be interested in "one weird trick..." and "free energy" ads. Don't worry, we don't hold the algorithms ad choices against your content.

[@ile84]

Air loom sounds like "heirloom" doesn't it? :D

[@ThinkingandTinkering]

yes it does - i wonder if that was deliberate

[@KronosGodwisen]

This is maximumly mechanical. Lovely.

[@DerekRoss1958]

One of the interesting things you could do with this concept is to have multiple rows of blades moving in opposing directions. Thing is that the chain doesn't need to go round the perimeter of a rectangle: it could go back and forth within the area of the rectangle instead.

[@htmagic]

RMS, make it a window width. Then make 2. Put one airloom wall on the lower floor, one on the top floor and let convective currents drive a small generator. Put one on each post and you might have an impressive power system to charge a bank of phones.

[@sammyvanhorenbeke6735]

About 2003 I played with a very similar concept, I called it the ‘waterpilar’ like caterpillar tracks. Imagine your square design would be elongated and would float/be semi submerged. The water would push the flaps and above water tucked in with little to no resistance turn. As you mentioned talking about is, is one thing making another.

[@colrodrick8784]

I enjoyed it too. I like where this is going Rob. Thanks for sharing

[@William_Hada]

Nice build on this design Rob! Works great. However, I don't see the advantage of this design over the conventional circular ones with a center axle. My feeling is that the chain or cable has a lot more friction to overcome vs the conventional ones with just a center axle, therefore less efficient.

[@kadmow]

Part of the limiting factor of a VAWT is that they don't generate (much) on the upwind blade (think as the lossy part of the cycle) - and the downwind blades are in the drag regime (think sailing boat) - putting it on a "conveyor belt"/zip-line/traintrack/loop- analogy, with a prevailing wind - the blades are mostly working on a "beam reach" - ie. fully acting aerodynamically with zero slip to the wind - as a wing should. Now (using a very thin track - ie. like a chairlift track the VAWT can approximate the duty cycle of a HAWT, with very few blades in the upwind or downwind legs - and they can be hauled by the working blades ( in the high power regime) of course as you point out, friction is the enemy - (so is g-force too, as with all VAWTS - at high rotational speed, - if they use- cantilevered blades need internal support). There are now many ways to tackle the "problem", steel wheels on rails are the most efficient (but a little noisy) - then we could use airbearings or maglev (on a rigid rail(s), now how to interconnect and attach to the generator (or maybe don't?? - haul a single cable around the loop, vs autonimous cars / - and multiple generator stages all around - or short independent trains chasing each other...vs a single huge bicycle chain - and several smaller - -distributed generators (like a long overland conveyor with several power units (now reversed as generators - OR take the cablecar idea and use 2 rows of cable for vertical support - and generate at the end wheels... . Then as you say - one could just set up a row of counterrotating VAWTs under the towers of a HAWT farm along a cliff-top - and generate an approximate amount of power -without the whole track setup..(there will be an upwind and a downwind blade (phase during for each rotation more) for each merry-go-round built.)... Models are good to play with - realworld vs digital, having a bit of fun is good.

[@ThinkingandTinkering]

well, they make bold claims and it certainly caught my interest - but that's where I am with it right now - lot's of investigation to do for sure

[@jimparsons6803]

Liked it. Interesting and thanks. Out if a field somewhere, I would guess that there's stuff that could get into the mechanism, wind-blown debris and so on. The 'cable' idea might reduce that, but not by much as there would have to be rollers and the like to support the cable.

[@janettehill8544]

It's great the way you turn a typical engineering concept on it's ear. I see that other folks have commented on the additional friction. Which was a thought that came to my mind as well. With larger proportional blades, the additional friction may be a moot point.

[@ThinkingandTinkering]

they comment on friction because basically they don't really understand chain drives and were they sit in real life power transmission applications

[@eugenevoltage1654]

Just discovered your channel, loving the huge variety of topics. I'm an engineer working with CNC machining alongside industrial 3D printers. Very cool to see how your opinion on printers developed and now you're using them for all concepts/prototypes. We have a Fuse1 SLS machine by Formlabs. It's insane, making large functional parts out of powder... and it connects to a 3 pin plug. I can see this type of machine being hobby accessible in 10 years.

[@hunnybunnysheavymetalmusic6542]

Gluing magnets and pickup coils along the edges of the links would surely work quite well.

[@ThinkingandTinkering]

i would think so

[@lorenedailey8691]

If I put an air loom system in my back yard I would make it multi-purpose. The support pole might as well have their own wind turbines. The spaces between the poles might as well grow beans, or be a clothes line. I have plans to make a merry-go-round generator for additional off-grid power because I'm looking for a mechical advantage to hand powered, power generating. With an air-loom system I can use it with wind power and hand power.

The age old argument of rimming a slack ring vs rimming a rigid ring.

[@goldcountryruss7035]

With the same blades between two shaft mounted discs, you would have the similar rotation with less parts and less friction, of course that would make it an articulated paddlewheel which would work well in a stream of water.

[@Lawrence_Marks]

You could still do generation at the rim though couldn't you? If you incorporated magnets into the individual chain links by making them a bit wider or longer, then put the coils above and below the chain links - they don't have to be circular in pattern in how the winding is placed in, right? So long as the magnets run perpendicular to the coil? My 3d printer has a huge queue so I can't get to this real soon (but I do have a new Creality K1 Max coming, YAY) - but I think that would be worth some fun trying. Will give it a go soon if I can get to it.

[@ThinkingandTinkering]

yes i think you could mate

[@hissst69]

Brilliant. could make snap together square frame bits to make a long one or larger square then the print bed.. or make a large frame out of plywood at desired sized.. I do have a question about direct wind square in it not blowing on one side, will the side and back all be pushed by the wind.. anyway.. brilliant brilliant stuff.. I love modular and this is the height of customizable and modular. I have a feeling this could be absolutely crush horizontal wind turbines of compatible size.. this is truely awesome, looking forward to your next videos.. I love the chain for ease of use but in application it is probably much quieter to use some sort of cable.. but the chain is absolutely brilliant for experimenting and mock ups.❤

Have you considered fixing each blade to the chain rigidly by its mid-point? It would turn automatically as it rotates. There would be less wear and tear and less energy loss due to flapping.

[@extraincomesuz]

Does the airloom produce more energy. Gates seems to think it will produce more energy than giant wind turbines with a lot smaller, cheaper, footprint. Yours works great but looks clunky and noisy. Airloom looks more kite-ish and it's supposed to have less noise. I am so happy you had a close up of the connectors on airloom. I think you're absolutely right that the generation is at those links and they are all basically the same. 🎉❤

[@ThinkingandTinkering]

mine is clunky mate - but then it is a simple model to explore the concept

[@st33ldi9ital]

Interesting... because of the design it wouldn't be that much more difficult to make it a hybrid solar/wind device. The fins could be solar cells.. the cable rigging could be wires... The fins could even be angled by adjusting the loops of wire/cable.

Wouldn't chain top and bottom significantly increase losses and increase complexity?

[@richardglickman7203]

I think the vertical setup would be better. Less stress on the sides of the chain as chains are designed to work on a vertically oriented sprocket.

[@arnswine]

Only trouble with the real thing is each tiny, high-rpm, high duty-cycle bearing represents a hard-to-detect, single-point failure mode. You should invent a sort of carrier\cartridge system for replacing and servicing as many spinning thingies as possible in a single window of opportunity. Also, the carrier\cartridge thingie could sport a rail of permanent magnets to interact with a linear arrangement of small, easily mass-produced, collecting coils (vs mechanically linked rotary generator).

[@ArbitraryOnslaught]

I wonder if you could increase the capture\storage by installing those folding opening and closing spring loaded sails. I cant remember the name but you showed them on another video. I imagine the shape you have would hit leading edge and open like a cup only to shoot by and closeup (repeat)

[@kaiwheeler64]

How about using V rollers like the ones on your 3d printer, to individually mount larger fan blades centered onto a single 3d printed V track? One roller on each fan blade could then be geared to, or directly attached to a dynamo. They could be tethered together as the airmine/loom is.

Possibility for multiple points of generation, I would like to see the blades a little longer for more torque, and add a Darwin type setup that's pushing the wind down from the top and up from the bottom to help focus it on to the blades.

Wouldn't it be better if the wind turbine blades were the opposite way round with the thin section at the hub and the larger section at the perimeter of the sweep? Generating more torque at the hub and capturing more energy.

Try to space out the blades like two feet apart more like the aroloom model to see what kinds of wind speed needed to get it going

Quote of the day: "When I get something in my hands, I can start to think about it." - Robert Murray-Smith, 2023 Jokes aside, in the first thinking phase, we tend to disregard qualities like flexibility and shape-caused resistance, because we don't actually know. We don't even *begin* to know until we've done some sort of mock-up, seen it react, have hands-on experience with it... The map is not the territory, they say, but more accurately: The forecast is not the weather 😉

If you added fins above and below the chains, would that increase the efficiency? If they were offset from the fins above or below would that increase further?

I feel like you could build this with sails fairly easy. Then it's just a belt hawt.

I was expecting a replication of a circle skylift mechanism. Cable holding a blade (the chair) with a pulley like mechanism at the pulls to pass the cable and blade.

that would work mate
