Solar Power

Numerous different solar oven designs have been developed and are cheap and easy to make in contrast to learning how to build a solar powered panel. Construct a box for your cooker out of MDF. I discovered small veneer pins to be exceptionally useful because they may be pounded neatly into the end grain of thin MDF and not split the wood.

They are sufficiently sturdy to be put to this use.

Now measure the size of the cube within the lined polystyrene box. You need to cut the mirror plastic to this size, and further line the box with it. Duck Tape is more than perfect for making good all the joints and securing things into place. Next, reflective surfaces need to be prepared. Use a bandsaw to cut a 2 foot wide strip of mirror plastic.

Draw a line extending along the edge of the mirror to the corner at a 67 degree angle, making a right triangle with the scrap plastic section. Now you have to mark up a string of trapeziums down the side of the mirror, where the shortest part is the same length as the inside of the cooker box. Use duck tape to join the mirrored reflectors on the non-reflective side so that the reflector side is on the top. Using Duck Tape permits you to make flexible hinges, which permit the reflector to be folded and stored out of the way. Take the stove to a sunny area to use. Positioning the rods supporting the reflectors will be far easier if you have somebody to hold the reflector at the right angle while you position and glue the support rod.

For practical, efficient cooking, heat needs to be captured and retained in the cooker to build up adequately to appropriate levels. If you don’t cover it up, all the hot air will escape. Oven heating bags are both cheap and simple to cook with. A pane of glass, ideally double-pane glass is an alternative solution. The glass should be slightly wider and higher than the lesser sized box, yet sufficiently small to let you easily take it out of the inner box. Using specular film instead of tin foil for the outside reflectors is an alternative way to make the stove better. This may not be used inside your oven since it is unable to withstand the high temperature. If you are pressed, you can heat up foods that have already been cooked (like canned goods) with the double zip lock bag trick. The food should be placed within a smaller zip-lock sack nestled inside of a bigger plastic zip-lock.

Whenever possible, place them on a reflective surface such as the reverse side of a bag of chips or a car sunshade. Of course solar ovens will not generate electricity, to do this you will need to learn how to build homemade solar panels.

Would you like to be able to soak in a warm bath when you are camping or your electricity goes out? Fill up some large soft drink containers with water, and set them on your car’s dash in direct sunlight. Close up the automobile to catch in the heat. Take a bath when the sun is at its highest. If you’d like to take a bath at night put the warm bottles in a thermo box. Alternatively you can learn how to build solar panels to power your appliances
