      Giant 'sand battery' holds a week's heat for a whole town
      from https://newatlas.com/author/michael-irving/
      A new industrial-scale 'sand battery' has been announced for Finland, which packs 1 MW of power and a capacity of up to 100 MWh of thermal energy for use during those cold polar winters. The new battery will be about 10 times bigger than a pilot plant that’s been running since 2022.
