Cardboard box solar ovens make a great summer project for the family. Not only are they fun to make, but they are also fun to make food in. You get to use an all natural souce- the sun!

Many things can be cooked in them. Hotdogs, English muffins just to name a few. Here we show you how to build one step-by-step.

Basically the idea is that a tower is constructed, and a large circle of the ground is covered with a material that sits 3-15 feet off the ground. Light can shine through the material, heating the air underneath the material and funneling it toward the only escape for the hot air, a tower at the center of the circle.

Here is a solar concentrator that I put together last year just to see what something like this could really do. This is a very powerful little unit. Solar concentrators have alot of potential in the renewable energy field due to the amount of energy they are able to collect from the sun.

Making a solar heater type furnace is not that hard as you will see I built a small one last year that just works. These are NOT toys and can reach temps of up to 350 F
