Solar Cooking
You can cook everything under the sun.
Where I live, here in the southwestern part of the USA, we have over 300 days a year that is sunny. Cooking with the sun is a great resource. No fuel needed. Just the sun and a reflective surface.

How do solar cookers work?
Solar cookers work by harnessing sunlight to generate heat for cooking food. They typically use reflective materials concentrate sunlight onto a cooking pot, which absorbs the heat and cooks the food inside. By utilizing renewable solar energy, solar cookers do not need fuel of any kind. No wood, propane or briquets. All you need is the sun. I have actually cooked in my Sun Oven on a cloudy day, it just takes longer.
Solar Cooker Designs

Global Sun Oven
This style of solar oven has been around for many years.
It was my first solar cooker. It is easy to use but bulky.

GoSun Solar Cooker
This was the second type of solar cooker I received. It was a gift from a neighbor friend. It is much more portable than our Sun Oven. It can also boil water.

Pop-up Reflective Cooker
This type of solar cooker stores well as it folds into itself.

Parabolic Solar Cooker
This type is very large and bulky, but it will get you your hottest temperatures. If you want to fry something, this is the way to go.

Homemade Box Oven
This is an cost effective way to start learning how to cook with the sun. It is especially effective when you use a Dutch oven inside to help retain heat.

Cast Iron and mirror Reflector Oven
Cast iron is very good at retaining heat. Cooking a stew with this method would be very effective.
