I did a bad bad thing by putting on the AC that day. Now I want it. LOL. I think actually the nights are warmer, so it's making the afternoons hotter. I'm still holding out...
In the meantime, here are some ideas for alternative cooling
using zeer pots, an evaporative cooling shelf, and a radiant solar cooler. If that last sounds contradictory, it's a pretty cool idea.
More solar and other alternative cooling ideas can be found here.
Ice houses! Spring houses! There are new technologies and old for cooling, but my impression is that none are really easy. Which explains a lot about the history of food preservation, doesn't it?
