Build This Solar Cooker Fast and for Under $6

Occasionally, we run across an item in our family preparedness journey that is not only valuable to the preparing/prepared family but is also simple, inexpensive, functional and readily available. The solar cooker we’re going to discuss is all of these things. Here’s where to find the plans for  this DIY gem:

We got the heads-up on this cooker from a good friend who was kind enough to introduce us to a close family member that has not only built one, but has modified/improved the plans you’ll read about and has some cooking experience that he can share also. Thank you “Cousin Martin”.

First, lets take a general look at the solar cooker as described by the posting at ‘wikia‘:

“The Fun-Panel solar cooker can be built in about an hour from a single cardboard box and some aluminum foil. This is significant, because traditional solar panel cookers such as the CooKit often require a large sheet of cardboard for construction. The Fun-Panel can also be adjusted more easily for different sun angles. This very powerful cooker is a true breakthrough.”

Here are some of the Fun-Panel’s advantages:

• “It’s easy to figure out how to cut and fold the cooker using the cardboard from half of a single box — you don’t need a big sheet of perfect cardboard. Every US Post Office sells a large cube-shaped box (20” x 20” x 20”) for about $6 that can be used to make two Fun-Panels.
• All cuts are 90 (degree) cuts — no curves.
• It is easily scaled to the size of cardboard box you have on hand.
• You can cook at all sun angles including low sun angles (morning and evening or high/low latitudes)”

Here are some of “Cousin Martin’s” observations/experiences:

• ’My experience with this very simple and VERY cheap-to-construct cooker has definitely convinced me of the practicality of solar cooking. It plainly has its limitations, but you really can cook without fire, without fuel, without smoke, and without electricity. Because it so cheap to build, it is very cost-effective. So many preparedness items involve $$ that are in short supply. This is one everybody can have, and the fuel is free.”
• “I cooked in the solar oven today. I put a sectioned sweet potato in at 11:30, in enough water to float the sections. I pulled it out about 2:00 and it was fully cooked. The ambient outside air temperature was 52 F and the official winds were NW at 12, gusting to 18mph, though I cooked in a wind-sheltered area. I re-oriented the oven twice during the cooking.”
• Here are three techniques “Cousin Martin” has found to improve the solar oven construction experience:
• “Scoring” the outer layer of the cardboard along the projects fold lines with a shallow cut using a razor knife
• Using a stiff straight-edge for the initial bends of the fold lines. Cardboard has a ‘bias“ because of its internal stiffening structures and it doesn‘t want to bend straight along just any line that happens to be drawn on it. The aforementioned scoring helps, but so does a stiff, straight board or piece of metal held along the fold line as one bends the cardboard.
• I used 3M general purpose aerosol spray adhesive (the Home Depot, <$5) to bond the aluminum foil to the cardboard after all the folds had been “worked into” the cardboard.”

A genuine “thanks” is appropriate here to PH’s friend and “Cousin Martin” for their observation and interest in providing preparing families with a great alternative cooking method for good times or bad.
Until next time; keep your eyes on the horizon as the weather’s changing fast.
