Slant faced solar oven from cardboard boxes

After building several smaller ovens from cardboard boxes and cooked with great success, I decided I wanted something bigger so I could cook a whole meal, including dessert in one oven. This one reaches well over 225 degrees once heated up for an hour before food is put in, then stays consistently at 200 until food is baked. This oven has 2 inch space between the two boxes and insulated with newspapers.
The inside is lined with heavy duty aluminum foil, glued to the walls and floor, a black metal roasting pan tray is on the floor, with metal racks, and several 1/4 inch thick ceramic tile painted flat black with non toxic paint are leaned up against the back wall, to provide stored heat when a cloud comes through and blocks the sunlight.

Anytime the sun is out, and no threat of rain, I put several ovens out to preheat and begin baking breads, bisquits, cakes, casseroles, meats as the day progresses. This saves on electricity in the summer not having to heat up a kitchen to cook food.

There really is no need to pay several hundred dollars on a solar oven when you can easily build a good one, many times, for less than a meal, costing 5 bucks.

All you need is several cardboard boxes, one bigger than the other, some aluminum foil, cheap school glue, and black acrylic, tempura paint, or non toxic when dry flat black BBQ paint, and large oven turkey bags.

You can build panel cookers that fold up and be taken with you to go camping without messing with fires if the weather is sunny.

But, you must be patient cause it is slower cooking since the temps are lower, but its well worth the effort.

i WONDER IF YOU COULD HAVE A SOLAR FAN IN THEIR TO CIRCULATE THE AIR TO STOP IT FROM STEAMING

[solarcookingnut]

@warrensavage You sure can! I have seen quite a few wooden solar ovens where they put computer fans in to keep the air circulating for even temps and keep the steam down. I just keep lids on my foods. I done this so that people could see just how hot one of these get. I rarely have problems with much steam since my ovens aren't air tight.

@solarcookingnut But doesnt it take from the point tof using less energy. Although I'm sure the energy required to run a computer fan is subtantialy less than to heat the oven,

@bluntley420 compare the use of an electric oven, :) there simply is NO comparison here to a mere little fan. all one has to do is simply.....set up a simple solar panel to power the fan. Lets consider this, Solar cooking saves all around in that if you DON'T solar cook, and just use your oven indoors, realize, you also run the central cooling system in your house to cool down the house while cooking inside. how much electric did you use while you posted this?

Using the solar panel in the first place

[solarcookingnut]

@bluntley420 My goal here is to help people incorporate methods of cooking here that will help them be less dependent on the grid. I am here to merely educate people, especially those who are low income and can't afford to buy solar panel systems. What I am showing is even a homeless person can do this without needing electric or other fuels. From what I show others, all they have to do is use their imagination from that point on.

I love the close up of the sizzle.

@bluntley420 The sun released it's energy ~ 8 minutes prior to earth receiving it; it isn't like adding another load to the electrical grid which requires another lump of coal added to the boiler to maintain steam turbine RPM, or taxing the rods that much more at a nuclear reactor etc.

The sun has no idea we use it's energy - it remains unaffected no matter if we had trillions of planets being 100% powered by the sun; it's lifespan is set in stone no matter how much its power is harnessed.

The temps always fall once food is put in. Steaming of the window is common with some ovens. Just wipe it off with a paper towel. some people leave the lid up just a tad bit for air circulation, but you can lose heat that way. try putting your pan of food inside a turkey roasting bag, then put in the oven, or use two large glass bowls to put the vessel in, capping one bowl over the other. Once the food is steaming hot is usually an indicator your food is cooking or already cooked.

Nice video! I built one solar oven with a 1/8x12x16 inches glass top. The box I used is from a print paper. The temp rouse to 250 deg F. When I'm cooking, the temp only reaches 215 deg or lower because of the steam fogging up the glass. Does anybody have a fix for this?
