"Precious" reflection from the cliff sent on November 16, 2022 (16:41) by Paolo P. 74 comments, 1415 views. [retina]

E' “Preziosa” ma…..….ce la possiamo permettere? L'ho ripresa “da casa”, all'uscita dalla Rade de Brest, una nave da crociera di 333 metri, 4.345 passeggeri + 1.313 di equipaggio. I suoi motori endotermici (di norma Wärtsilä o Man) consumano non meno di 120.000 Kg/giorno (circa 142.000 litri) di “bunker oil” che è circa 3.500 / 4.000 volte più inquinante del gasolio per autotrazione; giusto per dare un'idea, è il medesimo inquinamento generato da 82.834.500 (si, ottantadue milioni….) di vetture a ciclo diesel che percorrono, ciascuna, 100 Km. (Ho rifatto il conto un paio di volte, io stesso stupefatto, ipotizzando un consumo di 6 litri/100Km di una vettura media a ciclo diesel). I motori endotermici della nave producono solo elettricità, sia per alimentare i fabbisogni di questa città viaggiante, sia per la propulsione delegata a motori elettrici “azimutali”. Anche ipotizzando un rendimento globale elevato, dico fino al 50%, dato dall'efficienza dei motori più i sistemi di recupero termico ad essi applicati (vapore a media pressione dai fumi etc..), resta un disavanzo “delta S” di carico entropico pari a circa 732 MW/giorno utilizzati per scaldare mare ed atmosfera (valore assolutamente minimo poiché gran parte dell'energia elettrica viene poi ritrasformata in energia termica “di scarto” dai sistemi di climatizzazione, dalle celle frigorifere, dall'effetto Joule dei motori elettrici dei vari servizi). Per rendersi conto di quante navi siano costantemente in viaggio è sufficiente aprire vesselfinder.com E la Conferenza sul Clima ? spero si siano divertiti….. Personalmente ho conservato un solo discorso politico fra miliardi di parole spese a casaccio o, peggio, per demagogie dozzinali, nell'ultimo mezzo secolo. Lo pronunciò Jacques Chirac il 2 settembre del 2002 a Johannesburg “Notre maison brûle et nous regardons ailleurs”. Cosa è stato fatto da allora ? Era già stato detto tutto senza la necessità di alcuna esegesi. Chiunque abbia avuto potere, almeno da allora, è colpevole. Ma è stata solo messa la faccia di un'attricetta svedese a stupire un mondo di non vedenti, non udenti. Ignoranti.

You have taken this ship very well embellishing the image with an elegant color change. Wow what a view you have from your home, blessed are you. ( For the caption you wrote, leave me speechless, eeeh you just a great pollution, I also add the plane, in my part just raise your eyes to the sky to be disgusted by the plane strips that say it is water vapor, of course it is water vapor but in the middle there is also combustion to advance the plane and so on for everything that moves through fossil combustion, all a real disaster ..... . Hopefully well. Excuse the gossip). Hats off to you, Hello

Your analysis does not make a wrinkle, but you want to put a nice cruise trip in front of sacrifices on your lifestyle?
It is a losing battle also because the road we have taken for some time now towards extinction I believe is without return.
We don't deserve planet Earth!

I have never loved cruises although I have often refused this way of traveling.
Alas, to move to Sardinia I have to take the ferries.
This means consuming and polluting.
The world is set to movement and energy consumption.
To switch to less polluting sources will still have to spend a lot of time and we humans multiply.
Will we have time to stop this poisoning of the globe?
Your children and or grandchildren will have to see an increasingly bleak future with a growing environmental problem.
Nice shot for a reflection
that interests us all.
Hello Alexander

The photo is "clear" and the caption even more so!
What most people have not understood is that we do not have to save Nature... but Us!
Nature will survive anyway!

Nature always manages to evolve by adapting to contingencies.
We don't.

Come on.... that now with electric cars we solve everything :-P :-P :-P :-P There
are no words to describe stupidity.... human hypocrisy and greed....
But despite the fact that we consider ourselves smarter than any animal... I'm sure we won't get to inhabit planet Earth as much as the dinosaurs did ;-)
I fully share Paul... and I respect you .... because I find it right that at least someone writes that (unfortunately in a few) we feel taken for the c ... ulo....
