More #NoctilucentClouds over Europe this morning, an even larger show than last evening - but sadly mostly covered by low clouds in Bochum. See https://skyweek.wordpress.com/2026/07/18/die-leuchtenden-nachtwolken-sind-weiter-aktiv/ ("Das Morgen-Segment war heute ...") for a few more timesteps of this teaser that never delivered the main act here.
it was a good idea to get a ready-to-eat roasted chicken from the supermarket
chopped up the meat from the limbs to make some chicken & sweetcorn sandwiches with some fresh-ish bread (baked yesterday evening)
and there’s still lots of breast meat, i should think up something creative to do with it
“The bigger prize: shrinking network costs, not just reslicing them
[.] Demand flexibility is the mechanism. If heat pumps shift consumption away from the hours when the grid is most strained, less capacity needs to be built or reinforced in the first place. Our paper provides direct evidence on this: a heat-pump-specific time-of-use tariff reduced evening peak demand by 47%. That demand flexibility is the ticket to a genuine overall saving.”
