Anemoi Rotor Sails - m/v Afros Sailing

[@2MeterLP]

Whoever decided to print the brand name on those may have forgotten that the people on the bridge have to look at it all day. I dont think I could look at the branding rotate for longer than 5 minutes without my eyes hurting.

[@jetyoung-ja3891]

You don't see it with your eyes, the camera will.

[@pablomuzzobar8940]

yea u dont see it with ur eyes its just a blur. camera cant record fast enough

@@pablomuzzobar8940 You mean camera records faster

[@litamtondy]

@ Not really. If there were more FPS, our eyes would blur it like it would do in real life. So the previous person is right, the camera records too slowly.

@@litamtondy Yeah I guess it is a mix of faster shutter speed that captures the whole non blurry logo + slower frame rate that lets us perceive it.

[@Diego-we5ui]

Whoa I didn't think they would spin that fast

[@massimopiu]

@Diego-we5ui mmmh... i don't know: somehow too many fakes on the web, to be a "believer" at first watch... it needs more true-working check outs, but, It seems more impressive and suggest positive vibes.

[@dnomyarnostaw]

A terrific solution to reducing ship emissions.

[@bhawanisinghindia2287]

really amazing work...🌍👽🙏

[@jeanbecker3031]

Is there a comparison about the energy generated by a rotor and those of a Flettner system? Actually, both make most sense if the object they are mounted on moves rectangular to the wind.

[@hurri7720]

It's the same thing. en.wikipedia.org/wiki/Flettner_rotor

[@douro20]

I had no idea they spun so fast...how big are the motors which spin them?

[@madse9356]

Wind power 😀

[@douro20]

@@madse9356 No, there are electric motors which spin them. The ones on Enercon's hybrid ship are 70kW each.

[@madse9356]

douro20 aha! I thought they were passive like regular sails. If they need to be powered, how efficient can they be (taking up space on board with less room for cargo, stability mechanisms)? In another video, they claim a daily saving of $400 - is that with maintenance? Sure is interesting tech, really looking forward to see if it will be a viable tech

[@douro20]

The technology was already proven back in the 1920s. It worked well but the technology of the time didn't make it commercially viable since it took too much power to drive the rotors.

[@Enkrod]

A reduction of fuel consumption by 25% has been measured under very special circumstances before, but you'll get a more consistent reduction of 5%-10%. The Estraden has measured a mean reduction of 6% with her sails, that's 400 metric tons per year. They want to build a tanker with Flettners and because they can go bigger on a ship that doesn't need much of its space on deck, calculations show an estimated reduction of 10-12%, for that ship that would be 700 metric tons less fuel used per year. New production methods, new composite materials and automated software, controlling the rotation speed make this 100 year old technology finally economically reasonable.

[@Danielbode14]

God the maintenance work we seafarers have to do

[@paulskywarrior6943]

I wonder if they can apply also an current turbine for a vessel

[@tomasmuller5839]

Ah, der Flettner-Rotor!

[@user-km5mu7mg6x]

Imagine Prius and make it 1000 times bigger

[@jelly-eo6re]

hello ANEMOI, i'm working at ship building company. Althought rotor sail's height disrrupts wheel house's visibility, Does Ship Class give Ok sign to make a blueprint???

[@ChockPoint]

thanks very inpiring

[@paulskywarrior6943]

Wind power vessel is an acient but highly advanced and effiecient

[@davidanalyst671]

sure, these are great, but are they as great as some kind of cloth that is attached to the boat in such a way that it catches wind, and somehow moves the boat???

[@dnomyarnostaw]

Yes eight time's more propulsion for the same area, no heeling effect like sailboats, automatic sail trimming no matter the wind direction, fully push button operation

[@LogieT2K]

Plus the they dont take up deck space on the ship with masts and rigging that would delay loading and u loading making it more expensive and slower to operate the ship

[@isaac_aren]

Maybe not, but these require minimal space and training to use

[@2MeterLP]

Regular sail would triple the crew requirements, take up deck space and be in the way of loading/unloading

[@davidanalyst671]

@@2MeterLP huh. i guess you got a point there!!

[@richardfinnigan7458]

All of the drive down one side of the ship, how does that work?

[@MrCharliebbarkin]

I'm guessing the rotors interfere with loading and unloading the ship, so they only put them on one side while the other side is left unobstructed.

[@dnomyarnostaw]

With Rotors, the drive is perpendicular to the wind , and the best performance is on a reach, with the wind at right angles. There is no imbalance created by off set Rotors. There might be a slight imbalance if the wind is coming from the stern, but there is vastly reduced power to the ship at that wind direction.

[@kevinplatzer4058]

German invention; Flettner rotor; magnus effect

[@Coolgeorge48]

The crane obstructions, coupled with this, lookout will be nightmare, I'm curious to see how this vessel complies with SOLAS V/22

[@sisidmarinoyow5182]

It's foldable sir during cargo operations.

[@4s616]

How much fuel we save by this technology

[@whiteclifffl]

Not enough.

[@kanister21]

Up to 50% percent they said in a documentary.

[@whiteclifffl]

@@kanister21 Not true.

[@ParthPaTeL-wm3kt]

400 usd per day

[@markhoward53]

3-15% at current but new technologies will increase that

[@mrmoneyhacks5480]

I don't see how that makes the ship go forward any faster.

[@ikarus342000]

The rotor is also called a Flettner Rotor. He used the Magnus effect first. There are many youtube videos of how the system works

[@4s616]

I think we can also use in car

[@whiteclifffl]

No.

[@4s616]

@@whiteclifffl why

[@whiteclifffl]

@@4s616 Have you ever studied physics? There’s a thing called wind resistance.

[@2MeterLP]

@@4s616 For the same reason you cant put any other kind of sail on a car, the car moves too fast.

[@X02switchblades]

πως δουλευει αυτο???

[@X02switchblades]

mind blown!

[@user-yj4qz5lo6k]

Δεν θυμάμαι ακριβός but it somehow produced force towards the front. You can watch KZbin videos explaining it

[@LogieT2K]

They utilise the magnus effect to create an opposite force with propels the ship forward. Its pretty cool. I you throw a ball with a bit of backspin off a balcony or some high up it will travel forwards due to the same effect

[@JustLuckyYT]

My mom has these on her car so she doesn't have to pay 6 dollars per gallon

[@hswing11]

WIND MAKE ELECTRICITY AND POWERS THE SHIP.

[@m1leswilliams]

No, electricity spins the columns and causes low pressure perpendicular to the wind direction, pulling the ship along.

[@boomeranglord3035]

No wind? Crate it.

[@SkyDudley]

😵‍💫

[@H3Et]

Now the lookouts will be hauinted by ANEMOI for the rest of their lives.

[@ChristopheVerna_yovo]

Other sail for freighters : kzbin.info/www/bejne/r5e4o6CrjqmLnpI

[@WindThrusters]

I presume the thrust from the rotors just about compensates for the drag of the cranes - not ideal, but better than nothing and a step in the right direction.

[@matrcbt]

Wow

[@ShubhamBhosale2791996]

The branding on the columns shouldn't be this prominent, Imagine watch-standing 8 hours a day for 6 months just to stare at the big letters that appear to blink on the column, its so obnoxious

[@larrybuzbee7344]

Better keep the bearings greased. A failure there could make the great big spinney things go flippety flip in very dangerous and annoying fashion.

[@daviddavidsonn3578]

Imagine one taking off and flying into the distance... 🤣🤣🤣🤣🤣🤣
