@@kenneth9874 Don't change the subject. The sarcastic commenter was being incorrect on purpose and then you jumped him for being incorrect. That's what I'm teasing you about. C'est ca?
This can be debated. It was a rediscovery of sorts tho - ancient greeks and later the romans that used "borrowed" greeks to do the heavy maths for them knew of the power of steam and how to put it to use. Romans technically had everything to kick off industrialisation - they didnt because slaves where way cheaper...
@@billklatsch5058 A recreation of an invention is not a discovery. There are no steam engines in nature. An analogy I like to use is the wheel. The roller is a discovery - someone was pulling something heavy and it got easier when it ran over a round tree limb. But joining a wheel to an axle and mounting it in a bearing was 100% invention. The steam engine is just like this.

What about the Sharrow props that have been the rage in the boating news? I thought they were supposed to enter the cargo shipping industry soon. No mention of them here. I can't imagine an industry that would benefit more from increased prop efficiency than shipping.
its possible that the efficiency doesn't scale properly to the size for large ships. the complexity and expense of making a sharrow prop at the size required for large shipping vessels might offset any gains they would see. The large ships also see much slower rotation speed so the issues that the sharrow prop addresses may not apply.
Sharrow props have to be CNC machined. There is not a CNC machine anywhere on the planet even half the size that can make one. It’d probably cost a few hundred million dollars to make a CNC machine that large. Also props that large have variable pitch and you can’t vary the pitch of a Sharrow prop otherwise you’d see them on the front of prop planes as well.
@@ova578who told you that? I'm curious, I've been working on propellers since '96 and work in the largest drydock in the Western Hemisphere. We are at a point now where it's 50/50 with CPP versus fixed. I just did a set that were 40 foot diameter.
Voith propulsion units, although they make ships very manoeuvrable,they are not as fuel efficient as a propeller.I served in a Voith tractor tug for 15 years as an engineer,as well as conventional tugs.nearly 32 years in total.
Designing a specific propeller is structured work of art.
Thank you sharing beautiful ships.
No sailor would ever claim to conquer the seas.
I must admit that I am jealous of those Rudders receiving better care than what I get!😠

The steam engine was invented, not discovered.
Was steam discovered or invented?
@@RandyBaumery-s4ican you read?
can you read sarcasm? 😉
@@RandyBaumery-s4i not in your comment. Would like you to enlighten me, whats your point then?
Note that my question was if STEAM was discovered or invented. Of course it was discovered!! Haha
I find the whole process very interesting. Thank you very much. 😊😊
The scale of this stuff is pretty awe inspiring.
Nobody “discovered” the steam engine. It was created by creative engineers. Similarly to the Wright Brothers “discovering” the airplane.
And don't forget who invented gravity.
The Wright Brothers didn't "discover" the airplane, they designed and built the first one to fly 😉
@@kenneth9874 That's his point. It's a little thing called sarcasm🤠
@@badad0166 I guess even his grammar was sarcastic, similarly?

The "discovery" of the steam engine? It was an invention - they didn't find one buried under a tree.

Yes, indeed the video was pretty interesting. Keep them coming. Thank you.
Wonderful video.
giant propellers for ships

Thank you.
The "discovery" of the steam engine? Did they dig up a fossil engine or find one in the Amazon rain forest or something?
I think "development" is the word indicated here
Dont tell anyone but a steam engine can run on wood, turf and coal is known about 3k years just not in the west.
Do you guys film all these videos by yourself or its some stock footage?
99% stock they find. They cite the source in most of the clips it’s kind of obvious.
Azipod was developed in Finland.
I wouldn’t trust anyone who said that steam engines were discovered.
Can the propellers be made from stove eye plate metal?
What is between the double hull?
The steam engine was discovered? Alien tech left behind? (0:40)
6% Fuel saving is possible. It is proved in huge container ships (2 ships). Twice of those 3 %.
Hmm. no mention of azipod at all. How so? I think it is the the latest and best innovation in propulsion.
half the video is about azipods. The ABB branded units are all azipods.
If YOU are rich and desinformated, YOU should forget the windpower. A power, only for poor shipowners.
Very interesting.

@@brandonadams7837 most very large props are in fact not VPP. So that is not an issue

J’ai oublié mon chewing gum
On shaft system from engine room may be diametr of screw make bigger
and count r\ min of engine .... ?
in the same sentence it is A 'STATOR' then it is 'STATTOR'?
So which is it?
wow amazing ser,,

EPS = Expanded Polystyrene
der titel in englisch, und ich hätte keine zeit verschwendet.
Is it a Stattor or a Stator? @04:07
Ok
More of a "How it is made" for current tech. Besides mentioning da Vinci, not much history. Three points off your score.
Just photos but no tech info.

"can be traced back to leonardo da vinci" this guy hasn't heard of archimedes I believe. BS article
these shows are nearly unwatchable,
feels like a massive commercial
Yep. The robot is hard to listen to
The robot doesn't even know the difference between the words ship and boat. Ship is big. Boat is small.
Interesting that the robot pronounces the same word two different ways in two consecutive sentences. I am not sure if the author is just shy or what.
