Simple Solar DIY: Building a Fresnel Solar Cooker
Solar is one of the best ways to cook if you lose power due to a storm, emergency, or even if the grid goes down. Even in the winter time!
The problem is that unless you have a powerful system, it’s not very efficient, meaning you usually can’t cook very quickly or very much food at once.
Luckily, you can build a very powerful system using parts that you can find out of any trash dump, and you may even have the parts in your neighborhood. Either way, this project can be done very inexpensively and isn’t all that difficult to do.
Be careful when you build this beast though, it can melt concrete!
