Irreversibility "S" sent on November 30, 2021 (10:34) by Paolo P. 90 comments, 1362 views. [retina]

Entropia crescente, surriscaldamento…. La condizione climatica che fino a pochi anni or sono rappresentava la quasi quotidianità per alcune zone, è diventata occasione particolare e abbastanza rara. Da oltre un secolo si sta correndo dissennatamente verso un vertiginoso aumento dell'entropia, ovvero il passaggio dell'energia da una forma primitiva ad una forma diversa fruibile secondo necessità pratiche ma che, non potendo avere efficienza pari al 100%, ne trasforma una parte in calore. Ad es. il motore a ciclo “otto” a benzina rende ~ 30%, a ciclo diesel ~ 40%, trazione elettrica ~ 35% (se va bene, in funzione della produzione primaria della risorsa) e non parliamo dei riscaldamenti domestici o di qualsiasi lavorazione industriale. Tra non molto “andremo arrosto” senza possibilità di ritorno, eppure la fisica di base, ed i principi della termodinamica erano conosciuti da molto prima dell'escalation determinata dalla rivoluzione industriale e dall'esplosione demografica. In funzione dell'età potrei dire che non me ne importa molto ma cadrei nella medesima ottusa cecità di chi ha gestito opportunità di potere nel recente passato (in termini planetari) facendo scempio delle risorse in tempo brevissimo, con la logica che…… “il domani avrà cura di sé” (Matteo, 6-34) valida nella sua accezione evangelica ma non per la gestione energetica e la prospettiva di vita umana.

Beautiful this scene especially for the presence of fog; the fog I like is inside me .... too bad that for some years it is no longer like that of years ago.
Merry Christmas Morning Paul

Nice to meet you, Enrico.
I thank you for the nice comment and, again, I renew sincere wishes for every good.
Paolo
I was born "Padano" too and the fog is part of our being.

Eh, I have a weakness for these images shrouded in fog; I like it, bravo. [ 8-) very curious your note ... from Matthew 6-34 to thermodynamics 8-) ... but what you say is true: I too remember the cold when I was a child with ice in the ditches for weeks or months, the trees full of frost for days and the ice candles that hung from the roofs; .... on the first of January 2022 here in the Mantuan plain for the dense fog there were four degrees but climbing the Emilian Apennines there were twelve-thirteen; there were guys with short-sleeved t-shirts....]

Good evening Giancarlo, thank you for the passage and the complete comment; I too, born in Pavia, am part of those of the "low" where the summer heat alternated long periods of winter fog.
Now we have the heat left .....
A cordial greeting.
Paul
