Have thought about this article.
And now I've got some questions.
Do the sand batteries just use sand for insulation?
That would be so nifty.The article, from memory here, writes about the sand being heated up by hot air(?) and then says (?) this is resistive heating same as an electric radiator (?).
But these are different things. An error?There are quite a few disused concrete silos around. How they'd go with hot sand in them?
