Solar-powered cooking





You don’t need four burners and a gas line to make some great-tasting trail food. All you need is plenty of sunlight. Make your own solar oven and feed the whole group. Solar ovens work by bouncing sunlight off a reflective surface into a pot. The hotter the pot, the faster your food will cook. It’s easy to make—and cheap.

reflector-550

WHAT YOU’LL NEED:

  • A pizza box
  • Black construction paper
  • Aluminum foil
  • Plastic window covering
  • Permanent marker
  • Glue
  • Tape
  • Scissors
  • Ruler
  • String

WHAT YOU’LL DO:

reflector-1STEP 1: Line the inside bottom of the box with foil.

 

reflector-2 STEP 2: Cover foil with black paper and tape in place.

STEP 3: Set the plastic under the box and trace the outline of the box.

 

reflector-4 STEP 4: Remove the box and draw another outline 1⁄4-inch inside the first outline and cut along inside line.

 

reflector-5STEP 5: Close the box cover, and draw another line 1 inch from each side.

STEP 6: Cut along the lines on the front and sides—not the back.

 

reflector-7STEP 7: Open the cover and line the inside with foil.

STEP 8: Glue foil in place.

STEP 9: Cover foil with the cut plastic and tape in place.

STEP 10: All layers should be airtight and wrinkle-free.

 

reflector-11STEP 11: On the outside of the box cover, attach a string long enough to keep the flap open and let the sun shine in.

STEP 12: Once you have the oven, all you need is the sun. Choose a spot that will get at least several hours of direct sun away from any strong wind.

 

TRY IT OUT

Solar cooking takes a little practice. Try this recipe first:

Solar Oven S’mores

Ingredients:

  • Graham crackers
  • Milk chocolate bars
  • Marshmallows

Place graham crackers next to each other on the bottom of a black cast-iron pot. Black pots are best because they absorb and retain the sun’s heat better than light-colored pans. Top each cracker with a piece of chocolate and a marshmallow. Put a glass lid over the pot and place the pot in the center of your solar oven. When the marshmallow is gooey, take out the crackers and add the second layer of graham crackers on top to complete it.

    Love it!

    Ac tually it is quite workable.

    In one case something like this was shown to reffuges in a camp in Africa. One tribal group that seemed impervious to new ideas tried it and soon started taking courses in other subjects.

    Do a GOOGLE search on Solar Cookers, Solar Stoves, ect.

    Another good source “Fun With the Sun” by D. S. Hallacy.

    Simple cookers can be made from three reflector panels (like two walls and a floor), a dark colored glass jar with lid (to hold the food) and a plastic roasting bag. The three panels form a two walls, corner and floor structure. Put the food in the jar and add water to cover and close the jar. Put the jar in the bag. Put the bag in the reflector corner. Inflate the bag slightly and tie it shut. The bag helps to trap hot air around the jar.

    I have heard a rumor that if you lay a closed one liter pop bottle half full of water in the sun for six hours the water will get hot enough to kill microorganisms. I would advise against testing this method but try to see how hot the water can get as a Science Fair project.

    we are looking for a SOLAR POWERED RADIO XD

  8. Galactic Marine says:

    This is a neat thing! Great for when you can’t get a fire started!

  9. joe says:

    i can melt a candy bar in my pocket, what if i want a hamburger, or cook up some road kill? bogus.

    It like it!

  12. amby bamby says:

    wow i dont even knoazy how too make it lol im cr

  13. Okay says:

    I’m gonna get food poison and suit the magasine. The real American Way!

  14. Mr. Mustache says:

    It was a good idea but still flawed

  15. Anonymous says:

    I think it is a great idea and it sounds lightweight.

  17. Tomás says:

    I thought it was great!! By the way, I don’t want to sound rude or anything, but for those who asked “how does it get the heat?” the answer is the following: Light energy in the form of photons hits the black construction paper. The black construction paper absorbs the light energy, turning it into heat. The aluminum is apparently for centering more light onto the paper, therefore creating more heat.

    It seems soooooooooooooooo cool!0:)

  19. hott bunz says:

    i wish we did this in Girl Scout camp, but we only did the “Dutch Oven.”

    i want to tri it!!! this is my 1st time onthe website i love most(after 5 minutes)!!!;)

  27. byrdye says:

    it’s not actrually solar powered. it’s powered by heat energy

  28. Inventor8 says:

    sorry about sounding so mean but i watch the science channel for fun

  29. Inventor8 says:

    turnten itgetstheheat from the sun

    solar=sun

  30. wowowwowowowowowow says:

    yuuuuuuuuuuuuuuuuuuummmmmmmmmmmmmmm!\

  31. The Unknown says:

    There is also a way to make biscuits like this. Take a regular box and cover all sides with aluminum foil and tape it in. Take old wire coat hangers and punch them through, about three of the long ends to hold a pie plate. You fill another pie plate with coals from your fire and put the biscuits on the other pie plate above the coals, resting on the coat hangers. close the box and let them cook. They are great. You must make sure the whole inside of the box is coated in foil or else it will burn through. This happened the first time my patrol and I tried it, but the biscuits were still great. We laugh about it all the time now!

  32. meemles says:

    i love it. its brilliant!

  33. Dog says:

    Hey, Tumten the black paper absorbs the heat with reflection of the aluminum foil. It also sounds really COOOOOOOOOL.

  34. BOLTISTA says:
