CooKit Solar Cooker Made Out of Wood

The nice folks at Solar Cookers International gave us permission to reprint plans for their CooKit solar cooker in our book Making It. You can access those plans, as well as many other solar cooker projects, for free, on their website here.

I’ve made CooKits out of cardboard and aluminum foil a couple of times. One problem is that I eventually bang up the cardboard and I’ve got to make a new one. This summer I had a lot of  1/4 inch plywood leftover from fixing up Mrs. Homegrown’s writin’ shed. Rather than send that plywood to the dump I decided to make a more permanent CooKit.

I blew up the CooKit pdf from the SCI website using Adobe Illustrator.  I did a tiled printout and taped the pieces together to create a life sized pattern. I used this pattern to cut out the plywood pieces.

I spray glued the aluminum foil to the plywood. Next, I drilled holes in all the pieces and inserted twist ties to, essentially, create little hinges so that I could fold up the CooKit when not in use.

The plywood CooKit folds much better than my cardboard versions did.

This type of “panel” solar cooker works best for things like polenta and rice. Now I’ve got a convenient folding panel cooker for backyard use and camping trips.

  1. I’m interested in seeing how this works as well. I’m wondering how well reflective mylar sheets would work with that? You know, the stuff they use in hydroponics? I bet it would make that more efficient.
