In general, we have run heavy duty extension cords to the refrigerators, freezers and window air conditioner or heaters for the power outages that last longer than a day.
We’ve always had enough water and alternate cooking methods to get by for several weeks in this manner.
But longer term, I want a way to get water from the well - preferably from an indoor faucet - to fill 4 or 5 - 5 gallon buckets every other day. That’s the minimum for my kids, grandkids, and great grand kids.
Got room for a big stock tank?
I’ve a 10’ diameter * 2’ tall one that holds about 125 gallons
My 50’ * 20’ section of barn roof can pretty much fill it with a one inch rain.
