I am a packrat at heart and I am always looking at ways to make things from stuff and junk I have accumulated. I have been interested in trying to make a solar oven for a while.
We got a shipment in today that had perishable items and the box was lined with 1 think Styrofoam sheets. When I opened one of the box I realized that I was already on the way to making a solar oven. This is a very easy construct and with junk on hand the cost is ZERO. If you collect junk like I do you should be able to build this solar oven in less than an hour and still come up with good results.
Step 1: Parts and Tools
1 insulated cardboard box (BOX A)
1 cardboard box (small enough to fit inside first box snuggly) (BOX B)
1 cardboard box/cap to fit over BOX A (BOX C)
1 piece of glass – this came from a free scanner that was obtained for free off of craigslist.
Tape (shipping or duct tape)
Black spray paint
Clear plastic bag (zipper bag or twist tie)
Black or dark pot (small enough to fit within BOX B.)
Cutting board (optional)
Pencil, pen or marker
Step 2: Your First Cuts
Remember that anytime you use a knife or other sharp tool to practice responsible use... safety first!
Step 3: Paint It and Stick It...
Step 4: Keep a Lid on Things
Step 5: Staying Within the Lines
Step 6: Window With a View
Step 7: Lets Get Cooking
This will cook similar to a crock-pot and the best hours for cooking are usually around 10am to 3pm. Aim the oven at the sun and forget it. If you are able to monitor the oven you can reposition it through out the day and get a little extra temp out of it.
Get everything ready and load it in the morning and you should be ready to eat later that day.
