While I appreciate all the work that went in to the production of this video, to me, there was left a big question. What about the sluice gates? How do they work, design etc...?
Waitt... i read some article this concept are got inspiration from Chinese civilization.. the biggest and long human made canal are till here still in china..
Tgn
it's interesting that academia likes harping on his art and political patronage to the ruling families, his war machines and concept flying contraptions, but they never talk about his enduring practical and essential inventions we still use daily. it's almost like they want to relegate him to the past, instead of embracing his contributions to the level of einstein or newton, when in reality he contributed much more to how we live our everyday life than they did
This is kids level yes?
My dad did maintenance on the Panama canal and told me the motors to swing the lock gates were not powerful. He said the gates were so well balanced that a man could open and close them. The powerful unit was the mule engine that pulled the ship through the locks. The big maintenance item is keeping the upper part of the canal dedged
Cap.
Back in the Panamá days.
Your dad was the lead singer for the band "El Chombo", then he worked as a bodyguard for Gran Papi for a while.... Later on he became a stunt double in the 80's hit show miami vice.

@@deontaywallaceescalade who was my dad
@@ns6q333 need some info on him firts, bro.
@@deontaywallaceescalade LMAO Wtf
It's amazing how da Vinci stopped flow of water using its own pressure
It works like a reverse aerodynamics.
Parachutes!
Hydrodynamic
Indus valley civilization of Dholavira In Gujrat, India It has the same port system invented in 3rd BCE...used to increase and decrease the amount of water and locking it in ports during tides. ✨
(Edit-A slight mistake It was Lothal which had water locking system in Port and Dholavira had water locking dam system for water Storage.)
@@anishdesai7303can u please post the link of the source information ,i want to know more... Unbelievable if it's true.. Thank you..
The Chinese invented this same design in the Song dynasty in the 10th century, about 300 years before da Vinci was born. Just search up on China's Grand Canal, which still works to this day.
You've been such a great educator over the years, it's time to give something back so you can keep teaching others into the future

Great Video, superb animation and narration. It is amazing to think how the geniuses come up with such great designs and many engineers perfect it over time.
Thank you for your kind words!
@@Lesics was the warping problem experiences by engineers here
@@chaalakchatur8533 warping? Is the material of the gate inconsistent?
Used extensively in UK canals during the industrial revolution his idea turned into practical use and used in the Panama canal today, and still nothing as effective and simple to build (simple compared to rising and falling gates) he was an incredible man
Bruh the Chinese invented this type of mitre lock about 300 years before da Vinci was born. It was used in China's Grand Canal. No idea why this channel is ignoring that.
Sluice valves are mentioned once but never explained. It's as if you think their particular design mechanism is too obvious to explain. But how do they stay watertight? If they are part of the gates, how are they opened from the canal bank? Opening them against strong water pressure must be difficult too. If not, why not?
Everything has been explained in this video bro.
@@rohannampalliwar4526 what he ask was, what is the machanism of sluice valve (1:40) and how can sluice valve can be opened while inside the water?
@@rohannampalliwar4526 except the sluice valve. How does it work?
@@GemulChannel Forget about the sluice valves. Here's another way to level the water.

Thank you, I had the exact same question.
I live near one of the canals that Leonardo designed in the 15th century. They still have dams placed where he wanted them to be. He was such a great genius.
I was already to comment about the difficulty in how the two gates meet in the middle when closing, but the step at the bottom solves that. Brilliant!
Yes such a genius design
Bro was just on creative mode
Lesics as a channel is so damn underrated
I think. with 6+ million subscribers, this channel is not "damn underrated" (If that's what you meant?)
@@WuppertalerWanderWade Deserves more views TBH
@@someshyv Indeed
he mean this channel should be in billboard, tv, radio, tv news
@@eidodoos sadly on these kind of platforms everything is filled with entertainment not knowledgeable stuffs!
What about water leakage at the hinge posts? Do those have the same type of step as the ground?
They automatically get sealed like the middle V as the doors in our house do... or by cementing it (maybe solidifying earth at Leo's times)
@@tilak09 They would use cement in da Vinci's times as well. Why wouldn't they?
The veins in our body also have these valves to prevent the blood from flowing back o the organ
Yah, a very similar valve is there in the human heart. I should have included it.
maybe that's how Leo came with this idea. You know he was into human anatomy too.
I just randomly came across this channel with this first video. It seems like those simple informative videos that were made in the early 2000's that I was shown as a kid, It is much appreciated!
What prevents leakage at the hinges?
Nothing really, except well designed components.
A certain amount of leakage is acceptable in most canal systems.
He also decode the codex pages to upgrade ezio's hidden blade
Truly ahed of his t Jajabsbshdhhas
Thank you for this amazing demo
I finally know how they seal the bottom. It always bothered me how they seal the bottom
Just when I thought I had heard of all of da Vinci's genius inventions.
The sealing of the miter joint and the bottom is explained, but what about the sealing between the hinged edges and the walls?
OMG I saw this when I was studying in Scotland. I was fascinated by it and to know that this creation was hundreds of years old is astonishing
I have been around miter lock operations most of my life and have yet to see one that is watertight, no matter the level on the upstream side. It is theoretically possible, of course, with the right sealing materials installed, but in practice, that free joint in the middle is not constructed _that_ perfectly no matter how much pressure is applied. The leakage is generally not significant, so it is still the most useful design, but It is a very different construction type than, say, a precision airlock on a space capsule.
I was a tow boat deckhand, can confirm. The joint is always leaking water, just not enough to cause an issue.
I drove by a canal once and I cannot confirm or deny any of this
I used to be a miter lock door. I will not confirm or deny the claim at this time. I will be contacting a lawyer for assistance. 😛
yeah watertight is a bit of a superfluous detail. truly watertight mostly comes down to a matter of maintenance since a soft rubber could seal completely but would require regular replacement since every time the join flexes under the pressure cracking and wear also grows in the material. The real trick is that the pressure on that joint is able to be so large you can use quite hard materials as the seal (such as steel or other metals) which have much more favourable wear characteristics compared to most water sealing materials. The pressure also helps to reduce tolerances for things like squareness of the two doors and surface roughness at the joint (though they do still have a pretty tight tolerance for straightness at the meeting edge and parallelness of the two meeting faces)
In leonardo's time of course they didn't have so many options for materials and the only options for a water seal for that use case would have been wood or a soft metal like copper which means high pressure joints were the only option available to stop a notable leak. Nowadays most locks play with the wiggle room that a small leak is perfectly tolerable in their use case and so they leverage that to reduce maintenance costs meaning most do still let some water through
I am the water leaking through the locks and I approve this message
I was wondering how you make a seal around the hinge that rotates? Is it rubbing against the edge all the time?
I was also thinking exactly the same.
Thanks for improving our knowledge
Amazing combination between visualization and commentary! Very well done! You just got an other sub😊
Thank you for this great video! 👏🏼👏🏼👏🏼
Simple yet ingenious ❤️
That’s was really interesting, thanks!
I’m glad I learned that, thanks
Leonardo da Vinci >>> Genius Artist & Scientist ... 🌷🌿🌏💜🕊🇮🇹
Great explanation!
This is really nice explanation
It's helpful for me, thanks.
I love when something in a clever way is created to work with the forces & situations it's naturally going to experience & battle against.
Woww, this is an detailed video, loved your efforts
Great video, thanks for sharing.
Amazing video, totally got me subscribed
Good work lesics
Very easy to understand.
very good animation and explanation
Amazing visual 😍
So in addition to being a ninja, he also designed the Panama Canal gates. Damn, this turtle be putting humans to shame.
Cool engineering, had never heard of miter locks before this.
Amazing
Thanks
Coolness, thank sir Da Vinci.
God bless you.
so cool animation !
Brilliant idea 💡 ✨👌🏻
Awesome video
I agree with the person in comments who already said this - "Great Video, superb animation and narration".
Superb Video.
Excellent video. Thank you.
Informative video
great video i´m from Panama 👍
I travel the Trent/Severn waterways each summer . This was built in between 1830 and 1901 . They still use this style of gate. They can leak on occasion but solid. They change out the timbers when needed ,but really an amazing feat of engineering
That game style animation is quite pleasing to watch 😊
I've lived in several places along the Trent-Severn Waterway in Ontario, Canada. I can walk to one of them in 5 minutes. Most of those locks operate on these same principles, taking into account modernization of machinery and maintenance. It is a 386 km route with 45 locks. Also it's through some of the prettiest scenery available in central Ontario. The same can be said for the Rideau Canal system locations. That one is just over 200 km in total, using 29 locks.
Because they are no longer of use by commercial boating, and are for recreational boating, the staff are super accommodating to explain how everything works. It's simpler than I first imagined. Brilliant use of the water to do the work.
This was great to watch and da Vinci was certainly a gifted artist, engineer, etc.
During the video I got a memory trigger of something else that always intrigued me in terms of achieving a water-tight seal in order to hold back a large body of water. That is, the door/seal system on a dock, or dry-dock, to be precise. We've all seen a picture of a vessel in a dry-dock under construction, or in for maintenance, cleaning, etc. Here, the fluid dynamics seem in contrast to that of a river flow, pushing against the angled gate faces, using the flow force to achieve the seal (as shown in the video). Instead, the sea is 'flat' against the dock gate.
How is this achieved safely and reliably, anyone?
Thanks.
Thank you, youtube recommendation.

great page
Yep he was ahead of his time ,,,
and how do you prevent leakage at the sluice valves and how do you control them
Exactly. And the gate hinges too, don't understand how those don't leak.
The Magic of Arts and Science combined
Brilliant
Question, you miss something, how do you open the sloose gate and close it again once the water at equal height? What if the water was too deep? Do the operator has to dive to close the small sloose door again? I'm asking about the manual medieval version.
Awesome
The machine shop where I do NDT supplied the Corp of Engineers with HUGE gears and transmissions for a dam in Kentucky. A lot of work when into them.
awesome
How is water tightness achieved around the hinges of the gate? Is it similar to the bottom?
Vinci 🙏🏻🙏🏻🙏🏻
great explanatio
Wow....just wow
Hello Sabin, Thanks for your educational videos, very informative and engaging.
May I please request that you make a video on third-rail current collectors for electric trains (subway trains). If you have already made a video on that topic then please provide the link.
Appreciate what you do, thanks again.
You don't need to go to the Panama canal to see this. The nearest modern style canal will suffice. Here in Sweden some 10 km:s north of me, we have Göta canal: only a minor tourist canal, indeed, but every lock is of this type.
What about the leakage on both the edges of the gate and how do they prevent ??
The leaking is easy to compensate for in any canal or waterways
Very Nice Bro! Get Good People!
Thank you to see this video
Cool video
This video already seen
Amazing. Just one question. What about the point between the gate and the wall? how is that water tight?
I love the animation so much. Its so janky but so complex. Who made this?!
woo! genius idea
Great
we have these everywhere in the UK our country if full of Victorian canals in Liverpool there is loads of them near the old tobacco warehouse
I love you. I love you in every universe. It's not that I don't want to care or want someone to care for me. I'm just...In the grand calculus of the universe, my life is worth less than the millions still living.
You good bro?
@@johnmcdonald7644 looks like he ain't 😅
I think it would be the grand "calculation" of the universe. But do the ven diagram, you are also a part of the millions still living, so you put yourself in the awkward math situation of your life worth in a contradictory position. By living, you have a worth by the very nature. ipsofacto.
It's first time i get to know about this great invention. So amazing.
That Da vinci is freaking amazing....
Great video, commenting for better reach.
My dad would love this kind of technic
Water tight joints are the best ones, you can smoke even when it's raining
Where I used to live there was a canel with manual ones, never knew they were designed by da Vinci
Nothing more secure than a mitered joint!
Davinci was a person who wake up to early at 3 am when everybody still asleep
simple yet brilliant.
Unfortunately I don't think we can have renaissance men like Leonardo anymore, as the human knowledge have become so great, that no single human can know it all
NO, it is possible; you have fallen into the trap of thinking that you must hyperspecialize. You could easily become an engineer that researches physics that paints masterful paintings and makes life like sculptures. I, for one, have taught myself a bunch of musical instruments, drawing and painting, and physics & mathematics
Sounds like you just want an excuse to not try to become a master of such things
@@pyropulseIXXI what I am saying is that it is impossible to be a master of all.
One can be a master of one thing and good of many, but the world is so complex now that we need to specialise if we want to truly master anything, and only the brightest of the bright can even do that
Neither was Leonardo master of all. What made Leonardo different is that he was not yet subject to the division of labor and hyperspecialization that now governs society. His intellectual ability was that of similar people in his position. Polymaths weren't that uncommon during the peak of the Italian Renaissance as the Nobility, the Church and Merchants were all in constant struggle to control society and thus neither ultimately controlled it fully. This allowed sufficiently wealthy people to study and practice as they saw fit or needed rather than prostitute themselves to one particular task for the benefit of one of these sectors for the rest of their lives.
We could have Renaissance men again without much issue, the point of technology and knowledge is that it ultimately makes people more productive than the generations prior. You don't need to reinvent the gear or deduce Archimedes' law from scratch. Leonardo took a lifetime to reach his peak in art and material science because he had to collect that knowledge through experience and collecting rare books. Nowadays it only takes a few years for someone to match him, granted one has the resources, time and access to knowledge to do it, which is rare.
The promise of the industrial revolution and the Renaissance were that. No longer would you have to dedicate most of your life to tending to your crops as a peasant or serving your guild master as an apprentice. Mechanization would mean less work hours and more studying to improve society further. Unfortunately, the rulers simply saw mechanization as a way to make their lifestyle cheaper and more plentiful.
@@siraethelwulf8914 I am not sure completely what thy point is.
Was it that powers were divided between multiple factions back then and today its not?
Because we may call them something else but it is still basically the nobility (old money) the merchant (new money) and the church (moral crusaders) who are in charge.
Is it that there aren't people with the resources to just dedicate their lives to studying different subjects, because we have plenty of that. We don't even have to be rich anymore. Its just, most choose to spend their leisure time watching tv or writing dumb comments on youtube (I am referring mostly to myself here) then they are to pushing the boundaries of human knowledge.
Because that is why I think we can't have polymaths anymore, a polymath is someone who is an expert, someone who have contributed something important to human knowledge in several fields.
A Renaissance man is different from being a jack of all trade, because a Renaissance man is a master in many crafts, while a jack of all trades are competent in many but master in none
They use this at the Rideau Canal in Ottawa, Canada. Fun to watch
Jenius
My mind was blown so many times. I paused to try to think of a solution, but nothing as clever.
I’m not surprised
Jk
@@happybuggy1582 haha, not too far off though
This video made me feel smart 9/10.
Why did you stop uploading on your Sabins channel? Your inductor video really helped me visualise the concept when it was taught in class.
Can you make a video about how railgun works
Just like valves in heart
