Not a lot of use, I know, but I saw something on TV a while ago where they went through the "mechanics" of a passive larder / cooler - I think it had an opening to the outside, and IIRC there was a specific combination of rock types for the interior surfaces.
Do you have any measurements that show how effective this is? And what size fan is it? Ta.
