Exciting developments in solar.
Just read this fascinating FT article on perovskite solar panels – the next-gen innovation that's lighter, more flexible, and up to 20% more efficient than traditional silicon ones.
Imagine panels turning everyday surfaces into power generators

Prima che si scateni la cavalleria, sappiate che il valore acqueo è un gas serra importante però a differenza della CO2 condensa, ha un ciclo di vita di 24/48 ore e il grosso si distribuisce per lo più nei primi 3000/4000 metri di atmosfera. La CO2 non è condensabile, arriva a 50 km di altezza...1/2
Poi qualcuno si domanda perché ultimamente ci sono così tanti nubifragi.
Senza contare la retroazione positiva che un incremento della concentrazione di vapore acqueo ha sull'effetto serra complessivo.
