#efficiency of natural #lighting

“Les plus performantes de nos ampoules ne transforment en lumière que trente pour cent de l’éléctricité nécessaire à les faire fonctionner. Le reste s’évapore en chaleur.

Ce rendement est triple chez les animaux lumineux : poissons des abysses, calmars ou… insectes.”

(Erik Orsenna, Isabelle de Saint Aubin, Géopolitique du Moustique 2017)

(These lights are at the good new Victor brasserie at the Bozar in Brussels. The only picture I have of the animals mentioned by Orsenna and St Aubin is this one, from the Easter kite show at Châtelaillon-Plage –

– it seemed insufficiently serious.

The book itself, I find slow moving and over-demonstrative.)
