- The science behind the first Steam Engine largely consisted of creating a vacuum inside a vessel by adding cold water to steam.

By destroying an oil drum the team demonstrate how using steam the wrong way turned out to be the right way, thus demonstrating the principles behind the first ever practical engine.

'The Genius Of Invention':
Michael Mosley and team pick 12 inventions and explore how they have changed the way we live our lives.
Welcome to BBC Earth Science! Here we answer all your curious questions about science in the world around you. If there’s a question you have that we haven’t yet answered let us know in the comments!

A video titled 'How Steam Engines Work' did not teach me how steam engines work.
Essentially what you would have is a vessel making steam. Then mount a cylindrical drum with a piston in it above it. which in turn has a water box connected to it.
Once up to temperature, you can open a valve allowing steam to be released from the vessel into the drum, as pressure builds up on the underside of the piston it force's the piston up, when the piston reaches the top of it's stroke, the valve to the steam vessel is closed and another valve to the water box opens briefly allowing the water in. As this water cools the steam, the steam condenses back into water. As water is denser then steam the steam which filled the drum now occupies a much smaller space and so vacuum now exists where the steam used to occupy on the underside of the piston and so the corresponding higher atmospheric pressure above the piston forces the piston back down.
Once the piston reaches the bottom of it's stroke the valve to the steam vessel opens again and the process repeats.
@@louiscypher4186thank you for filling it in! Much appreciated
This clip didn't actually show how how a steam engine USED this effect to derive mechanical work from the effect.
calculon000 they never claimed to
"I want to show you a demo of how using steam the wrong way was actually using steam the right way." @1:12
This is a clip of a much longer show. Not long after this clip they do show how it's used.
waww that's amazing every time you see things in practical that is the best way to learn and you will never forget
A better title would've been "The effects of Atmospheric pressure on a depressurized barrel"
Wow!!! Geniuses! Best video ever on atmospheric pressure vs vacuum.
Great demonstration of Atmospheric Power!
So, why call it a Steam Engine?
Not all early machines were powered by Atmospheric Pressure.
James Watt's machines were powered by Steam Pressure from the start.
It's an Atmospheric Pump, not a Steam Engine, it provides Atmospheric Power.
A Steam Engine's different, it provides Steam Power. That's why it's called a Steam Engine.
James Watt dumped Newcomen's Atmospheric Power and Arkwright's Water-Power for High Pressure Steam Power.
To achieve that he had to invent a new machine, the world's first PRACTICAL Steam Powered Engine.
It was no ordinary invention, it changed the world!
It WAS the Industrial Revolution!
This just gave me a visual if the submarine that imploded but not how a steam engine actually works which I know the basics but wanted to learn more about the valves, rods and pistons and the type of hardware used like bearing types and gears and the dissipation of energy
As y'all across the pond would say that was bloody brilliant.
Rename the title to " How to ignore handshake "
the video says''how a steam engines work'' there is a wrong with the spelling
Nice
James May wants his shirt back!
do I need a TV licence to watch this?
RIP Michael Mosley.
Just found a use for that old drum at work TY lol
Where can I find this episode +BBC Earth Lab ?
The content did not actually show how steam engines work... bruh man v have asked for candy from a wrong house lol
I'm big fan of steam engine James watts is a great inventor 😎
wow
Click bait...
"It killed people left, right, and center. It was...
(sunglasses)
a dead end."
ooooWAHHHHH
I watched this for the reactions
where do I watch the full vid
Search "Genius of İnvention"... this video is from 1st episode of the show
0:03 where may I buy a machine like that? 😍😍😍😍
See the great thing about the BBC is that they can manage to waste five minutes of your time and still not tell you what they promised
So this is what happened to that titan submersible
Reverse the process and you could also show how James Watt's Steam Engines works.
The first TRUE Steam Engines.
By the way, how come nobody shows how James Watt's Steam Engine works?
That poor drum
Britain from 1800 to 1900.
20,000 Waterwheels decreased in number.
Windmills decreased in number.
Englishman Thomas Newcomen's 1,500 Atmospheric Pumps
disappeared. They didn't change the world.
Scotsman James Watt's 500 Steam Engines and their descendants increased in number to 10,000,000 !!!
They did change the world.
For every SINGLE Waterwheel in 1800 we now had 500 Steam Engines in 1900 !!!
That's an increase in the whole country's available Power Supply of 500 times, in one human ( possible ) lifetime !!!
And it was all due to only one Invention, James Watt's Invention of the world's first PRACTICAL Steam Powered Engine.
No Steam Power, no Industrial Revolution.
I wonder... Can this become a science project?
why are they both holding empty mugs
Reverse Films The woman isn't. You can see her spill coffee on herself at 2:35
hi
Call it by it's proper name. It's an Atmospheric Pump, not a Steam Engine. It was a 70 years long dead-end. It changed nothing, no Industrial Revolution, that had to wait for James Watt's Steam Engine, it supplied Steam Power.
Newcomen's Pump wasn't powered by Steam, It was powered by Atmospheric Pressure and it supplied Atmospheric Power.
It's not the principal behind James Watt's Steam Engines, which were the first ever PRACTICAL Steam Engines.
Reverse the process and you'll have the principal of James Watt's engine, a real Steam Engine.
The title should be, how an Atmospheric Pump works!
There's an Industrial Revolution's worth of difference between Watt's and Newcomen's machines.
Ahah this guy is everywhere
I know the BBC is completely useless, but is there any quality control at all? Look at the title: 'How Does a Steam Engines Work?' It should be either 'a steam engine' or 'steam engines'; the indefinite article is not placed before the plural form. Perhaps if you actually focused on quality rather than half-baked ideology, people might consider paying for a TV licence, rather than abandoning you for Netflix, the Internet, or just giving up on the entire medium of video.
Where's my main man Greg Foot? -.-
Blak 👋 We're putting up an original film every Thursday and an archive film like this every Tuesday. So a couple more days until my text original one 👌
Ayyyyy, it's Greggayyyyy. I'll be sure to watch the text original one you put out :>. Ty for replying :>
Why are they holding mugs?
Implosion. IOW what happens when a stricken submarine exceeds test depth.
who came here for classwork
Me
I did
For the toefl
I like trains
it's that -trans- trains guy.
Daksh Joshi you know it boi
TrainMaster15 OHHH look it's that trainsgender guy!
2:47 Cringe
So how does a steam engine work?
Heat water it becomes steam that expands 1,699 times the volume it used to be pipe the expanding steam to a piston it pushes the piston turning a crank you pipe steam to the other side of the piston and push it back turning the crankshaft and so on.
Not big fan of these type of videos. Like there so much blabber to make it "interesting" but you barely learn anything within the large amount of time wasted
They Wasted 3 Minutes and 25 seconds Of My Live With There Worse Content
