Curious, can this be used in reverse, to keep sand cool and use it to cool down houses? Would bring down a lot of AC usage in tropical countries.

- weberer 4y agoNormally they just pump sea water since that's usually below 20 C anyway. https://en.wikipedia.org/wiki/District_cooling https://en.wikipedia.org/wiki/District_cooling
- calaphos 4y agoA major problem would he that the temperature delta for storage will be way smaller. There isn't really space for the same 500C below ambient in that direction :)
