A solar oven is a cooking gadget that receives 100% of its power from sunlight. This characteristic makes a solar oven environmentally cordial as well as portable, because it requires no gas or electricity to operate. It's also easy to make and store one, so you won't need to set aside much space.
You'll need the following tools and materials:
Umbrella, Aluminum foil, Cooking pot with lid (black is better), Hacksaw, File, Black duct tape or electrical tape
Hammer, Beaker tripod and wire gauze, Uv protection glasses or sunglasses with polycarbonate lenses, Work gloves, Meat thermometer (when cooking meat)
Step One: Solar Oven protection and Design
Understanding the way solar ovens work and knowing the precautions you should take is leading before you begin development your own. Basically, a solar oven cooks food by using the light and heat power contained in the sun's rays. You'll be able to accomplish temperatures approaching 300 degrees Fahrenheit by focusing this solar energy. This is hot enough to cook meat as well as boil and sterilize water, but it can also give you a serious burn so you need to be careful whenever you're using it. Wear standard protective glasses to prevent your eyes from being damaged by Uv light.
Step Two: Apply Aluminum Foil to an Open Umbrella
The reflective outside of a solar oven focuses the sun's heat and light, and aluminum foil makes a fine reflective outside when applied to a fully opened umbrella. Open the umbrella until it locks, and then cut a two-foot strip of foil for each of the umbrella's sections. Next, cover the umbrella's edge with foil, then apply one of the two-foot foil strips to a section of umbrella, ensuring that half the strip is on each side of the umbrella and there's an even overlap on each side of the divisions. Overlap that first strip with another strip of foil on the inside of the umbrella, and apply tape to keep the foil in place. Repeat until the inside of the umbrella is wholly covered by aluminum foil.
Step Three: take off the Umbrella's Handle
While you're wearing work gloves and polycarbonate glasses, cut off the umbrella's handle with the hacksaw, 1 centimeter above the umbrella's locking mechanism. Plane out the sharp edges with a file, and then hammer those edges toward the center to originate a beveled shape. This can help prevent accidental burns while your solar oven is being used.
Step Four: How to Use the Solar Oven
To cook something with your solar oven, first open up the umbrella and lock it into place. Next, point it toward the sun, using rocks or other objects to prop it up and keep it aimed at the sun. Insert the tripod into a level portion of your solar oven and position the wire gauze on it. Fill your cooking pot with food, put the lid on and then place the pot on the wire gauze. Make sure that it continues to point toward the sun while your food is cooking. Finally, when you're cooking meat, make sure you use a meat thermometer to be inevitable it's cooked to a safe temperature.
