I want a generator. The ideal one would run on natural gas or propane from a tank in the yard. My primary misgivings are the noise that the device produces becomes a magnet for hungry people who didn't prepare to take your provisions. Refrigeration is the top candidate for the generated power.
Powdered whey protein, bars and shakes fill the protein void adequately without need of cooking or refrigeration. Water is a necessary adjunct to those sources.
Make sure it is quiet enough so the neighbors don’t hear it.
Gather some wood, buy charcoal and lighter fluid and fuel for the Coleman.
Right now, print out some simple cardboard and foil solar ovens instructions. I think the one I made is a cook-it pattern. It’ll cook up a pot of rice and more. Buy some foil, tape and get a toilet paper box for the cardboard. Read up on how to use it. It’s not so much the outside temperature but the sun’s rays. Or buy one.
You have a small water source in your canned goods. Don’t dump the liquid but use it.
Inverted generators cost more, but use less fuel and are much quieter. Youngest child has two generators, one of which is inverted, and survived three weeks without power. Now he is looking for a dual fuel one.
