I need to look into propane refrigerators. It might be a good option for us.
The appeal of the solar/ice maker concept is its longevity: not being dependent on fuel that must be purchased. If an outage goes on for a loooong time, a cooler with a ready supply of ice could be like my grandmother's icebox that she talked about and could make a big difference in our lives. It looks pretty portable, as well.
And A/C is a big deal, but people lived a long time in the South without it. Check out the older homes, like the King William district in San Antonio, that have a way to open tall windows at top and bottom, to let hot air out and cool(er) air in. They also used fans and screen porches to beat the heat.
In the Southwest, the very simple swamp cooler is the "A/C" for many homes. In Las Cruces, few houses had "refrigerated air." We did fairly well with our flat roof and swamp cooler. I did the maintenance of both every spring. I miss the simplicity and low cost of both.
Thanks,
