With a little thought and preparation, you can solve many of your electrical needs safely in the event of an extended power outage. The do-it-yourselfer might want to make their own portable solar power supply, or put a 12 volt motor in a small swamp cooler to solve those electrical needs.
When I give seminars to school age children on solar cooking I usually see a student with a clear bottle of water and I ask them, "did you have to get that water out of a river running behind your house? Did you have to dig a hole in your yard to find that water?" They laugh. Millions around the world have to get their drinking water every day that way.
It is not fun being without air conditioning in the summer. Several years ago we had our house unit go out on the hottest day of the year. It was 126 degrees F in the shade and even hotter in the house. Fish were dying and we were miserable. After searching for two days I finally found a window swamp cooler that got us by until we could get the house air conditioner fixed.
I use my Global Sun Oven to cook anything that I would normally cook in my regular oven. My family loves fresh-ground wheat bread and we regularly cook roasts, cookies, rice, casseroles, baked potatoes, cakes and more. I can't tell you how many times I've been told that sun cooked chicken tastes better than Kenny Rogers' rotisserie chicken (and I love K.R. chicken).
For emergencies there are all sorts of hand crank lights, solar flashlights, and low power LED flashlights. There's even a "shake-up" flashlight that uses a shaking motion of the hand to produce the needed power.
Developed in 2017, the STI-H250™ is consists of two linked torsion beams that rotate simultaneously following the sun's path. They are moved by just one motor, cutting supply and maintenance costs. STI-H250™ dual-row tracker includes backtracking mode to avoid shadowing between adjacent rows and stow function to protect the tracker in extreme wind conditions. For cleaning, vehicles can pass between trackers and each row can be placed in a different position.
