How 2,000 Tons Of #Sand Stores 100 Megawatt-Hours And Slashes Carbon Emissions 70%

"#PolarNight is doubling its size with a new 250 megawatt-hour facility in Vaaksy, #Finland, which will output 2 megawatts of energy consistently. That newer and bigger battery will use only slightly more sand – 2,400 tons – because the #SandBattery’s design renders it more efficient with size. What will become the new world’s largest sand battery is already under construction and is scheduled for completion in summer 2027."

Inuvik, Northwest Territories 🌑 Polar Night. No sunrise today, but plenty of cold. We’re sitting at a bone-chilling -40°C with clear skies. The stars and Aurora are the only light we’ve got, but they should be spectacular tonight!

High: -35°C | Low: -41°C

Tip: Check on your neighbors, especially elders, during this extreme cold snap. #Inuvik #NWT #PolarNight #ArcticCold #AuroraBorealis

Beautiful clouds at 14:33 on 26th December. Polar stratospheric clouds if I'm not mistaken. This North it's somewhat bright only around 11 - 14.

Spending a few days in Lapland. This was the view from our cottage 10:00 in the morning. Probably in about an hour or so it will be somewhat bright. The sun rises here next time 7th January.
Merry Christmas and happy holidays to all who celebrate
