Thank you sharing beautiful ships.

I find the whole process very interesting. Thank you very much. 😊😊

Note that my question was if STEAM was discovered or invented. Of course it was discovered!! Haha

I must admit that I am jealous of those Rudders receiving better care than what I get!😠 😅😅😅

Nobody “discovered” the steam engine. It was created by creative engineers. Similarly to the Wright Brothers “discovering” the airplane.

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

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.

half the video is about azipods. The ABB branded units are all azipods.

6% Fuel saving is possible. It is proved in huge container ships (2 ships). Twice of those 3 %.

What is between the double hull?

Propeller made the ship moved not to make it float, just guessing. The question is what makes the ship float...?

I wouldn’t trust anyone who said that steam engines were discovered.

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.

@MascottDeepfriar

10 ай бұрын

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.

@brandonadams7837

10 ай бұрын

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.

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.

in the same sentence it is A 'STATOR' then it is 'STATTOR'? So which is it?
