Man. Your work is amazing, and sooo underrated. Even though i am an engineer and i already knew the concepts, i loved the way you break down and explain the phenomena in such a simple way so that anyone can understand them.
The attention to detail is amazing! I can notice where one fact smoothly flows to the next, and each piece of information is clearly segmented. You deserve more subs!
Did a paper on steam power last semester. Really mind-opening stuff and is the perfect way to understand where much of the world comes from. And what's fun is that many people think that the steam engine is gone, but the reality is that it just evolved to be much more efficient as a turbine than as direct kinetic power. Most of the world runs on steam power via electricity generation rather than it's earlier locomotive usage.
Well, you can figure it out yourself, although you can't be certain about it. I think it works like this: When water cools down the steam and the pressure in the cylinder goes down, the valve of the boiling water and that other valve which I don't remember the name of opens. And when the steam fills the cylinder again, the valve of the water opens due to high pressure.
I think the original question has not been answered yet: how are the valves opened and closed? For example, does person need to do manually (at 12 cycles per minute I think that this would be feasible, especially if someone needed to just flip a lever) or is it done by linkages? Or it could be bit of each, with person doing the first openings and closings, and maybe doing timing adjustments while the engine is running. I saw an at least partly manually controlled engine at a museum at Kew, London, UK some years ago.
The first commercial steam-powered device was a water pump, developed in 1698 by Thomas Savery. It used condensing steam to create a vacuum which raised water from below and then used steam pressure to raise it higher. Small engines were effective though larger models were problematic. They had a very limited lift height and were prone to boiler explosions. Savery's engine was used in mines, pumping stations and supplying water to water wheels powering textile machinery.
I've never seen any Factories Powered by any Savery Pump or Newcomen Atmospheric Pumps. In Britain from 1800 to 1900. 20,000 Waterwheels decreased in number. Windmills decreased in number. The Englishman Thomas Newcomen's 1,500 Atmospheric Pumps disappeared. The Scotsman James Watt's 500 Steam Engines and their descendants increased in number to 10,000,000 !!! For every SINGLE Waterwheel in 1800 we now had 500 Steam Engines in 1900 !!! That's an increase in total Power output of 500 times for the whole country!!! And consequently it's production capacity. And it was all due to James Watt's Invention of the world's first PRACTICAL Steam Powered Engine.
Very educative. I learn a lot from you. In Africa, teaching is not detailed and no teaching aid for instruction. Your animation simplified the concept. Now I know the myth behind steam engine. Thank you
If you want to talk about "the first engine *ever*" then you're wrong on at least two counts: 1. Thomas Savery built the first steam-powered mine pump in 1698. 2. Hero built the first steam turbine in the first century AD. The Newcomen Engine was merely the first *practical* engine.
@@martijnverschuren3578 That's a fair point, this applies only to steam engines which in turn are a subcategory of heat engines. Clock engines are typically powered by gravity or spring tension and when you include those power sources there are far more exceptions. Even if you limit only to heat engines you still find plenty more examples which pre-date the Newcomen Engine.
The tree of technology is so important. We take everything for granted these days. We don't realise how our everyday lives were created thanks to some innovators like Newcomen starting three hundred years ago, leading to all comfort and convenience and safety. Without them we would still be riding horses, burning candles for light, living in our villages, and dying early.
This is what I'm thinking about for a long time. 3D rendered educational videos. Maybe some day it can even become a standard. I can already see where this idea can grow: interactivity, so it becomes Interactive 3D Unreal Engine Educational Simulations. We can expand this even further: VR.
That's exactly what I was thinking when I started. I even learned a bunch of Unity before deciding to animate in Blender. Making interactive 3d models and lessons are a little ways off still.
I could not agree with you more about this engine. Ninety nine percent of people do not realise what we owe to this engine…basically everything! There is not a product or process that could not be traced back to this engine and the ones that came after it. Then there is the subject of metallurgy. Now that we are inventing these new engines, what are we going to make them out of? Let’s invent cast iron. Ok, how are we going to machine it? Let’s invent tool steel. The development of engineering also lead to the creation of new standards. George Whitworth standardised threads, nuts and bolts etc. I would say that the Newcomen engine is the greatest invention of all time, possibly only beaten by the wheel. We can only speculate how the world might have turned out it this engine had not been invented. Great video.
I showed up here after watching the Technology Connection series about lanterns (and, essentially, pre-electricity light), in which he shocked me by mentioning that the (now) basic concepts of combustion weren't understood until the 1770s...That really sparked my interest (no pun intended). I wanted to understand the origins of a piston-driven engine, and this video was a lovely explanation. Now to find a small-scale Newcomen engine to set up in my back yard. I'm sure the wife won't mind XD
ARGH, Real question becomes how are the valves working and how are they piped. Intake manifold and exhaust manifolds are always something I have a hard time picturing in my mind in 3-D models.
It only takes 2 lb of steam pressure to fill a 44 gallon steel drum but when the drum is sealed and the steam condenses the drum will crush under the force of the atmospheric pressure on the outside surface.
I would love to see a video in this level of detail about Watt's innovations too. Hell, I would love to see a video in this level of detail about pretty much anything! Congrats! I can only imagine how many hours were spent to achieve such a quality.
According historians and books, the first steam machine was patented by Thomas Savery in 1689. But in 1600, almost one hundred years before, Jerónimo de Ayanz had patented in Spain, one steam machine similar to that patented by Savery. These machines were used to pump out water in flooded mines, and is the first use of steam with industrial purposes; this device it is considered to be the precedents for James Wat's steam engines

There is a working replica in the Black Country Museum near Birmingham UK. There is also an original one, still in its original building near Barnsley.
why use a cooling condensing stroke as a power stroke and not the high-pressure steam? If you use steam to drive the piston, the discharge can charge a second, larger piston and that steam, still at pressure, can then charge a third, very large piston. Plus, the ability of the water to cool the steam is limited, requiring extra plumbing to be less efficient than a water jacket. If the piston started at bottom, the rocker alone won't lift the piston - the rocker is like a flywheel; if it was off-balance, it wouldn't work.
Newcomen's engine was simple to build at the time with the technology they had. So even though it was not very efficient, it was much better than the animal power that had been powering the pumps before it. The mine owners saw how much better it was and were happy to spend the money to get one. And when Watt made the pitch that a pressure powered engine would use much less fuel to do the same job, the mine owners were happy to pay the higher price for the new engines that were more complicated, and harder to make. Machine tools got more accurate to bore the smoother cylinders that the Watt engines required. A whole cascade of technological improvements were kicked off by Newcomen's invention.
Gotta start somewhere. I remember my grandmother had some ancient encyclopedias and I looked up internal combustion engine and about all it showed was as far as new experimental engines used in the NEW automobiles people were building. It was mostly about the Otto cycle ( as a new thing ) and I vaguely remember it describing someone before Otto trying to make a piston engine run on gun powder. The encyclopedia were so old I remember looking up television and it didn't have ANYTHING I often remembered that that whenever someone like ' Mythbusters ' would bring it up.
The valves were operated by links and rods which were moved by the rising and falling of the inner end of the beam. There were handles attached to them so the could be set by hand to anticipate the starting of the engine.
I don't understand: 1. Who turns switches to let water in and out? Is it manually? 2. How do you make a perfect vacuum with a piston than can move with an atmospheric pressure but also can lift tons of mass?
Great video but the title triggered one of my pet peeves. The first steam engine turbine was the Aeolipile. However the engine you described was the first one to be useful in any way shape or form.
It depends on your definition of an engine. Heron of Alexandria invented many steam/atmospheric engines. Waterwheels were in use already in the bronze age.
how the valves of the cold water opens up? what is it that triggers the valves of the cold water to open up ? this was an important part and insight. others than that im satisfied
The valves were operated by links and rods which were moved by the rising and falling of the inner end of the beam. There were handles attached to them so the could be set by hand to anticipate the starting of the engine.
The trick is using some mechanism to control the valve operation. (Not quite shown in this video though, although the rest of the principle behind it is explained.)
I think the start of the cycle is when the steam pushes the piston up and the beam to the water pump goes down. If not, how does the beam go back up once the steam turns into water?
@@kissi1859The weight on the Pump side pulls the piston back up and sucks Steam into the cylinder. When the Steam cools down it changes back into water and creates a vacuum, then the weight of Air sitting on top of the piston pushes it down. The cylinder is open at the top.
Clarity is in the eye of the beholder, I suppose. These were the most confusing drawings ever seen. Like that baby elephant trained to hold a paintbrush.
I really like the format. I think your descriptions are good except for the atmospheric pressure. In the case of the steam you are using a change in energy so the balls should bounce a lot and bounce less depending on the energy. The atmospheric is a static pressure so it should be a matrix of balls just sitting on top since their energy is not being discussed. It is essentially an unchanging force like a barbell weight on top of the cylinder.
No. Atmospheric pressure is exactly what this author depicts. It is the sum of the forces that the atmospheric air molecule bounces to the surface divided by area.
This looks the same as the Cornish Machine still functioning in The Cruquius gemaal in Haarlemmermeer in The Netherlands. The main cylinder with a diameter of 3,6 meters driving 8 pumps like the one here. Each stroke delivers 64 cubic meters of water 5 meter higher!

This is such a great video! what controls the opening of the valves though?
hand with fingers or magic
The valves were operated by links and rods which were moved by the rising and falling of the inner end of the beam. There were handles attached to them so the could be set by hand to anticipate the starting of the engine.
At first, the human operator. But, apparently, some of them were lazy, and fitted automatic mechanisms powered by the pump beam.
I don't understand:
1. Who turns switches to let water in and out? Is it manually?
2. How do you make a perfect vacuum with a piston than can move with an atmospheric pressure but also can lift tons of mass?
