En lisant ce livre: https://www.editions-ulmer.fr/editions-ulmer/produire-son-electricite-autoconstruire-son-installation-photovoltaique-829-cl.htm , cela donne très envie de s’y lancer !
Je n’avais jamais entendu parler des batteries NIFE qui ont l’air super intéressantes au point de vue écologique ! (30 ans de durée de vie, robustes et bonne recyclabilité)…A voir si cela se trouve facilement quelque part :)

Today in #Spain people is scared to death by news:
Core of The #Earth -that #NiFe of #HighSchool days- has stopped spinning
First of all, today #ElPaís echoed a paper of #Nature, according to which core stopped spinning around 2009
#Core very hot at very high pressure is made up of two regions: inner solid and a cover of liquid Nickel and Iron: this means that Core is uncoupled
from the movement of mantle -old SiAl and SiMa- of Earth
there is no gear between the two spins
Not END OF THE WORLD
