We cooked with a number of different solar ovens that we made from nested cardboard boxes. We had a few prototypes and the last one we made, we used
for 3-4 years while living on the beach near Mulege.
A good book is: Heaven's Flame: A Guide to Solar Cookers, available on Amazon.
You can buy the pre-fab ones, but they are expensive. We probably spent about 10-15 dollars, all of that on buying two pre-cut pieces of glass that
to fit the top of the oven and for the oven thermometer and aluminum foil. We used good, thick, recycled boxes, one that fit inside the other with a
gap of a few inches. This space was stuffed with pieces of cardboard for insulation and sealed. There are a number of designs out there.
We then made our own reflectors and lined them with aluminum foil. The above mentioned book gives good plans and designs, talking about the ideal
size & proportion for your oven (too small or too big won't generate enough heat) as well as how to make the reflectors.
We cooked rice, beans, stews, soups and even brownies in our oven.
You have to monitor and adjust the oven to keep the temp. up at maximum, but we easily achieved 320-360 degrees for 5-6 hours on a sunny winter day on
Bahia Concepcion.
Think: slow cooker. Once you make it and adjust to using it, no more gas or electricity.
Just make sure to figure a way to fasten your reflectors so they dont fall over. Rocks work well to prop the oven, with a string tied to the
reflectors. Putting it in a protected place also helps. Amazingly, we never had problems with dogs wandering by to raid the oven, even though it sat
right on the sand in front of the palapa and we commonly went away for a few hours. But, quien sabe?
Good luck! |
