Simple Solar DIY: Building a Fresnel Solar Cooker<\/a>.<\/p>\n

Cooking is a rather natural use for solar power. We all know how the sun warms things that it strikes, leaving the inside of our cars hot and making us sweat on a sunny day. Many of us have also played with magnifying glasses as kids, using them to light dried leaves and scraps of paper on fire.<\/p>\n

That power can be harnessed in a more structured way, making it extremely easy to cook with. Scientists have built solar furnaces which are hot enough to melt iron. While you don\u2019t need anything quite that hot, a simple solar cooker could be a great piece of survival equipment to add to your collection.<\/p>\n

There are several different designs of solar cookers you can make, but the most effective uses a Fresnel lens. Fresnel lenses are flat plastic magnifying glasses. If you\u2019ve ever used one of those\u00a0sheet magnifiers<\/a>, you\u2019ve used a Fresnel lens. They consist of a flat plastic sheet that has concentric rings molded into the back side. The rings act in the same manner as a regular magnifying glass, with the exception that each ring is a separate thin magnifier.
