I Built DaVinci's Windmill-Does It Actually Work?

[@Imaboss8ball]

Honestly i think the fact that you seem to still be operating in a suburban neighborhood is probably whats holding you back. If you owned a larger field with a larger workshop you could build these large projects to scale without concern. The base for this windmill is way too short and no where near wide enough to even be considered useful. I mean windmills need access to stable wind. Low height with fences and trees interferes with that.

[@web1bastler]

Absolutely my thoughts as well. In order to power a grindstone he'd need to gather at least 600W worth of shaft power. Ideally 1kW or more. Anything lower wouldn't be feasible as it would get lower than the power of two people (~500W) and require so much reduction gearing (causing more mechanical losses) to be far too slow.

G'day, The Numbers are...

Turbulence involves Asymmetric Windspeeds (And thus, Lift, Drag, & Torque on the opposing Blades when they're Horizontal. And that invokes Gyroscopic Precession..., Manifesting in ALL the stored Kinetic Energy resident in the Rim of the "Flywheel" being focussed across the Axis of Rotation..., but Applied 90° later - in the Direction of Rotation... Basically, Turbulence ,in the upwind Air Column will Violently Stop the Rotor from Spinning, with Vertical Impulses, as it Yaws out of Wind, Hammered by big Cyclic Jolts of Gyroscopic Precession... Look into my Playlists, to see how I KNOW this to be true... (I still have the Remains of my Skypower Mk 4-c Wind Turbine Rotor..., after I attempted to "furl" it when over-speeding in a strong Wind). As the Tail attempted to Yaw the Disc out of Wind, Gyroscopic Precession duly Pulled the Bolt-Heads & Washers through the Main Bearings' Pillow-Block Mountings. And, thus, one Blade hit the Tower, at 600 RPM+... The largest Splinter off the other Blade came over the top and speared into the Ground, about 3 ft from myself, at the foot of the Tower.

Hi Andy, love the video. I am a bearing engineer and appreciate the attempt at a rudimentary thrust cylindrical roller bearing. In order to prevent your wobbling issue, you need to add more rollers to increase the load sharing and fix the rollers along their pins so they stay in the same rolling path and do not slide axially (this will prevent slippage and reduce friction). In order to accommodate an increased number of rollers, you may need to forge a more advanced cage design that maintains roller spacing. You may also consider a larger roller diameter to increase load capacity. Also be sure to grease adequately. Love the content!

[@Neoprenesiren]

THIS also bearings on the top and bottom of the vertical gear to reduce energy loss to friction. Separately reducing the mass of the sails which he spoke on a bit. AND setting the gears to mesh better / easier to again reduce energy losses.

"grease adequately" is just solid life advice in general

[@creamsiclem4433]

​@phalange2021 I was wondering if they could make one of the sail crosses able to slide in relation to the other. Giving the sails variability of pitch, perhaps linking it to the centrifugal regulator. This would allow them to catch or spill the wind as necessary.

The main flaw of this type of windmill drive is that it will try to turn out of the wind the moment a load is applied to the driveshaft. You can see the problem easily if you imagine the central shaft as fixed. Then the dive gear will turn the blades out of the wind. To make this work you need a guiding sale with at least the same surface as the sum of the wind blades itself. Secondly support the central shaft at the bottom with a "nail in a cup" bearing. you create a shallow iron cup and polish it on the inside. Ten you cut the end of the shaft to a point and set it in the middle of the cup. Lubricate it with a lot of lard. Repeat that upside down at the top. This will create a stable and "low friction" bearing that can hold up the windmill. The outer tower is only there to hold the central shaft upright. You can size up such construction up to 1hp. Beyond that friction will be destroying the bearings.

[@Varadiio]

Right, this is like a helicopter without a tail rotor. You can test the spin of your blades and find no issue, until you do "work" and lift off the ground. In this case the body of the windmill is trying to spin rather than impart that work. If we're trying to maintain DaVinci's concept, we could consider a seer/pin relationship with the tail sail. We need "NOT" logic. If Tail Sail receiving wind, seer is disengaged. We still need a tail that can overcome the shaft's backlash, but it's not constantly fighting it, even at such a slight angle that the tail sail is receiving very little energy. The seer could just be a rod or pin with some amount of sprint force down onto a radial set of locking grooves, which is overcome by something like a rotating or twisting of the tail section. When the wind is at a significant enough angle and speed to disengage the pin spring (spring tension could be adjusted for the workload) the wind also imparts closer to its maximum force, providing the excess energy to overcome the work and reengage the pin at a more favorable angle to the wind.

[@lawr5764]

[@JOUST-2]

And now you see why very rarely see small windmills. The power of the wind becomes useful only with larger sails, hence the use of water and water mills; the inertia and momentum of water carries so much more energy that it makes it so much more efficient, especially material wise... But as you stated, its not given to all to have a running stream close by, contrary to windpower. All in all, was a great episode! Neat to see you all learn from the past iterations of the wood gears and the progression of knowledge and usage of metal working with the rollers ! Very cool to see :) Looking forward to the next episode!

[@DisKorruptd]

One thing that might help would be if Andy made some ropes and pins to tether the windmill down with. the problem is that the wind is allowed to pull the machine over without anything resembling a foundation holding it in place.

[@Varadiio]

This was basically stated above, but I think this also adds to it. Being in a low, fenced area is not helping. A larger windmill is a more stable platform for a taller system, and height is the only reasonable way to get more predictable and uniform wind flow.

Not an expert in windmills, but was a former Technology & Engineering Ed teacher. A few things come to mind watching this 1. I love how you're taking design ideas from minds like Da Vinci 2. This seems like a great proof of concept to show that you were able to make something at least somewhat functional. Does it work perfectly? No, but it works 3. I think some of the other factors you're limited in are the height and location for a windmill. Most windmill are made to be very tall (where winds are stronger and more constant) in areas that have less to interfere (I'm sure the trees, fences, and buildings nearby are at least somewhat blocking wind)

[@joe2marrow]

Hey Andy, as someone who got a degree working in alternative energy and works on windmills I think you had the right idea with the large blades at 15° angle to give to ample surface area for it to work. However with that amount of surface area being taken up your tail needs to be further back to give it the best chance at turning the face into the wind. Also with that minuscule amount of energy you will be able to capture I highly doubt you will be able to spin a grindstone. HOWEVER! I think you would have a good chance of making it work if your yaw was attached to a belt that would climb against a screw and drop crushing the grain Monjolo style.

[@rexmcstiller4675]

In Guédelon in France they build an medival water mill an had also problems with binding at the beginning. After a while it runned smother and had the same wear marks than found of medival mills. So those wooden gears just need time to work them self in.

[@sasssquatch1467]

I work as a maintenance guy for a factory. We call it "wear time". Imperfections in parts or imperfect pairings (due to new parts being put in an old machine) tend to wear each other into smoother interactions over time. The knee jerk reaction most people have when they repair or build a machine is that it "doesn't work, try again". But really, they should just run to the shit out of the machine until it either breaks or works better than ever.

[@vreeze33]

There are a quite a few small windmills in the Netherlands used to pump water. The old big ones are the ones that are well-known, but to protect smaller plots of land there are tiny ones. Most wind powered pumps have been replaced by modern pumps but some are still in use. The ones I've seen are made of metal, which probably makes them a lot more efficient, and smaller than the one you built, size varies depending on how much pumping is needed. Theremay have been wooden ones in the past. I tried to google for some images but I couldn't find what I was looking for. I have no knowledge of the actual engineering. I just remember seeing some. It's very windy here so that probably helps, too. Edit: Apparently the tiny windmills have been given the nickname "Bosmannetje". These waterpumping systems, regardless of size and method, are called a "gemaal". If you search for the two terms combined you should be able to find some pictures. From what I could find this type began being used in the 1930s so probably no wooden ones. Besides a tail, newer designs also have one arm that catches wind to create a better angle.

[@theomelchior2739]

[@GusCraft460]

Precision has a very specific meaning in manufacturing and engineering. Modern precision didn’t exist until the beginning of the Industrial Revolution. The way that you can achieve precision begins with three blocks of granite or cast iron. You rub two of these blocks (we’ll call them blocks 1 and 2) together until they perfectly fit together. We then switch out block 1 for the third block (block 3) and repeat. Then we switch out block 2 for block 1 and repeat. We keep repeating this whole process another two or three times. At the end of this all three block should have a perfectly flat surface, and I mean *PERFECTLY* flat. That surface is the beginning of precision. From there onwards it’s all a material of geometry. So that’s how you create precision with rocks and math.

[@ClashBluelight]

@@GusCraft460 That's really cool, but weren't there prior methods too? Like the ancient Greeks and Egyptians creating perfect circles, triangles, and squares from one another, from which they then created perfectly flat surfaces. I remember reading about how the creation of geometry unlocked the world of precision all the way back then, and saw videos with examples of foundation stones with perfectly flat faces as evidence. Edit: Oh yeah, I almost forgot. There's also the antikythera mechanism. That required mechanical precision, and was ancient in origin.

[@No.Good.Nickname]

​@@ClashBluelightyou can also achieve perfectly flat things by using water as a spirit level. But I don't know how much it was used by regular people.

[@GusCraft460]

@ there’s precision, and then there’s *precision*. While many ancient cultures could do the geometry part easily, without a perfectly flat object to use as a reference you can’t get modern precision. Ancient cultures could get as precise as about 0.1 mm, but modern precision can go to as little as 0.001 mm. The difference like the difference between making wood screws you trust to hold two boards together and the screws that NASA uses to hold their rockets together.

[@Jon-yv4iu]

Wind tends to blow only from two directions in any location and one of those directions is directly opposite the first. So long as you have an accurate record of that (called a Wind Rose or a Wind Compass) the whole need for a swiveling windmill doesnt seem needed. It would let you capture energy from 90% of winds at a location without needing a swivel. Then again Davinci isnt exactly known for coming up with the simplest solution for any given problem (lookin at you "just add a connon for each direction you might want to shoot")

[@MissMerc]

That style of governor is why we have the term "Balls out". When you run an engine "balls out", it's "running as hard and fast as it can."

[@kirkpoore9871]

I think it needs to be noted that the horizontal windmill was invented 300 years before da Vinci was born and was in common use across Europe in many forms. The da Vinci sketch certainly shows the basics, but you have also uncovered the drawbacks in his design-a weak and unstable base, an undersized wind shaft, a tail mechanism which might be overwhelmed by wind pressure on the actual sails, etc. I suggest looking into medieval and early modern post mills for further design clues. (For what it’s worth, I have built a small 17’ tall medieval post mill that I’ve used to grind wheat.).

[@samstewart4444]

I have a photo of a middle eastern design where the central axis sticks out several feet. Guy wires go from the end of the axis to the tips of the sail supports and to the vertex of a triangular shaped sail. Note, only a single, light weight piece of wood supports the sail much like the mast on a ship. The angle of the sail can be adjusted by the length of the guy wire (again, much like a ships sail).

[@davidhitchcock6398]

That would lower the weight of the sails which would be a big help. Also reducing the sail arms even slightly (thickness, taper, drill holes) will also help lower the weight letting it turn better.

[@diegoparga9324]

This video reminded me of a story my aerodynamics professor told us in class. A military guy consulted with him about using an old helicopter propeller as a wind turbine. My teacher said it wouldn’t be feasible because the airfoil geometry in both applications is different and not interchangeable. The military guy ignored the suggestion and built his wind turbine anyway, but it did not work. He came back a year later to consult with my professor (paying by the hour, of course) and asked how to make the turbine spin. The answer he received was certainly not what he was expecting because my teacher said “go buy an electric motor, attach it to the turbine and turn it on”

So on the sails- one of the things you want is going to be longer, thinner sails. You'll notice this on real-world windmills and turbines, as well as on propellers and stuff. Long, thin aerofoils (which is what sails are) are able to get more oomph from less air movement- it's why gliders have such long thin wings- gives them more lift at slower speeds.

After you test more smaller blades, you could also test wooden airfoil propeller blades, to see if using the heavier wood with an airfoil shape would be better than using angled cloth with a wooden frame.

[@deadcell66]

An honest question. I've heard that brass and bronze are kind of self lubricating, so wouldn't that a good plating material for the nut instead of straight up greasing the wood. I feel that's also why the rotation was more easy than getting spin. The rollers probably reduced drag a lot, while the wind blades had quite a bit of drag to overcome with the nut, but definitely also the gearing.

You need to attach the tower to a firmer foundation or the wind is going to push it over with how top heavy a windmill is. Attaching the millstone directly to the bottom could solve this, but while you get to that point, get some sand bags or some concrete bricks and weigh it down at the base with the weights firmly attached. I am talking by hardware or ropes you would use on a sailing ship. Steel cable is beyond your tech tree still, but that would be the other option.

[@ravenpineshomestead]

I'd argue you'd want larger sails, the weight of the sails versus the limited potential pounds of thrust from the wind keeps it from spinning as well. There has to be a sweet spot where your sails are large enough to harness the pounds of push needed to spin, and the weight of the sails are no longer hindering it(sail weight vs. Potential ratio). I'm sure my terminology is atrocious but i hope im able to get the point I'm trying to make across.

[@IvoTichelaar]

I am Dutch and as such windmills are a big part of my heritage. I have a book about the structure and construction of windmills, and there is actually a lot more in the book about how to build a strong frame, than there is about the sails and the gears. A proper windmill was built with an octagonal tower. Hexagonal was acceptable because it was a lot cheaper and still pretty sturdy. Square towers deform too much with varying wind. The timber frames are massive, with intricate joinery. Basically, Leonardo's windmill focuses on the exact opposite. He shows detail in the gears, there are token shapes to illustrate the functioning of a windmill (make no mistake, this is just a diagram of what was an already well established type of windmill), it's definitely not a functional design. All things considered, I think it was more successful than I had expected, which is likely your contribution. Well done.

[@Wishbone1977]

I imagine that making the tower conical (broad at the base and narrowing towards the top) rather than straight up-and-down is also important to the structural stability.

[@jeffreyyoung4104]

[@simonfraser3332]

I think it would get more wind if it was higher, im thinking like those wind turbinids. not only is wind stronger the higher you go but it would also be above the roof line of houses so incoming wind wont be blocked or slowed down.

[@kittyprydekissme]

I was wondering if perhaps the sails and the wood framework for the sails are too heavy, and cause the axle to tilt. That would cause more friction and that could be the reason it won't spin much. Maybe you need a counterweight on the opposite end of the axle. Did you soak the wood before steaming it? Does anyone know if a windmill would work well for grinding pulp for paper?

[@yeetmcmeat]

I'm not an engineer or a woodworker, so my 2 cents aren't worth much, but my intuition is saying that the shafts you're using are only just enough to work. with the size of the sails and the gearing there has to be a lot of force on the shafting, both an axial and torque load. If you are going to build a more permanent version, adding any thickness to the shaft will help.

[@AB-Prince]

Not to cast shade but, believe it or not, craftsmen and engineers from ancient times (even far before Da Vinci) had materials and craftsmanship that exceed some of your experiments, leading to more reliable operations. Realizing you don't have the time to build those skills, you might consider more modern construction methods and materials to put you on an even playing field of those ancient craftsmen.

Seems the vertical shaft needed support at the bottom to keep it from tilting the head around. Also a pyramid style base will add a ton of stability to keep it upright in winds. Youve proven it does work just missed the mark in overall execution.

[@blackhawk15897]

I think that your biggest problem was that your base is just too short and wasn't anchored down. The sails and gearing were great, but you just didn't have them high enough. Wind speeds pick up and get more consistent the higher you go and the less you have obstructing it. Your backyard is surrounded by trees and fences, and your tower didn't even get the sails above your roof. You were never going to catch any decent wind with that setup. Your tower would need to be at least two or three stories tall before you started getting decent results.

I could be wrong, but I believe the steam turbine is the most efficient type of steam engine.

Something to think about when you revisit the steam engine.

While a good steam turbine is more efficient than a piston steam engine; I doubt the same holds true for anything HTME could achieve.

[@gibberishname]

i know right?! It's the same vowel in wind and mill. HOW do you end up with such different pronunciations?

[@Guru_1092]

​@@gibberishnameI'm just joking around and poking fun at his pronunciation. Otherwise it was a good video.

[@tonyberg8382]

It’s a Minnesotan accent… we soften “I” in for example Milk and Mill and “A” in Bag

[@MrJmagenta]

What about a different design in general, a Panemone windmill ala Sistan and Baluchestan

[@thecrazy8888]

Was the tower anchored?

[@ludecom-cz1wz]

Groovy.

[@xpndblhero5170]

"I want to play w/ wind power" and "anything weak" never mix well... If you want to go that big you're going to need a better frame and anchor to the ground and possibly even guide wires. I can say w/ complete confidence that 2x4s will not work, you're going to need 4x4s or 6x6s as a base and possibly even buried just to keep it up against a slow wind.... There is so much force oce you get over a few square meters of area, it gets ridiculous real quick. It's like trying to carry a mattress by yourself in a strong wind... 😂😂

Need better bearings everywhere, the shaft going to the gearbox, and the top that rotates.

[@CaptnApathy]

could you make a ball bearing with wood instead of the rollers you made? da vinci did make those too.

i can't believe you've overlooked the easiest power of nature to harness: slave labour

[@ThomasSchannel]

They did in the early days with interns, though they knew too much on how to do the things and overshadow Andy a bit

[@cvspvr]

@ThomasSchannel annaliese could've overshadowed a thousand andys

[@DH-xw6jp]

I believe they are called interns in the modern world.

Have you missed the dog video?

[@ericwilliams1659]

I would place money if he asked dozens of people would show up and volunteer their labor for a day or weekend.

[@Hex3d-v5y]

Put the windmill higher in the air
