Cooking with the Sun on the Navajo Reservation in Utah

This was a really interesting entry. Here several Navajo students from Paul McCarl’s class at the Whitehorse High School in Montezuma Creek, Utah present their solar cooker projects.

Especially interesting is a Fresnel lens cooker the students built in order to be able to fry the popular Southwest fry bread.

As one of the student notes, you don’t see too many solar cookers that will fry.

The students introduce themselves in Navajo and then go on and explain their projects.

Intro to the box style solar oven/cooker

This is a video produced by the manufacturer (or a distributor) of a brand of solar ovens/cookers (both terms seem to get used). As this is a commercial item it’s been realized to a really high standard but as the overall technology is simple and solar ovens in general aren’t hard to make, I like to think of the SunOven displayed here as inspiration.

If you don’t want to DIY, you can of course buy a SunOven. They retail for upwards of $200. Neat features it has: it’s parts fold up to make it portable, a cooking shelf that adjusts to how you’ve angled the oven and an adjustable foot to let you change the angle (to face the sun as it moves in the sky) more easily.

The presenter here does a really good job of explaining the features of a solar oven and how it works.
