just driving down the road and BAM, right to the back of the head. gotta tell you, unlimited texting to email myself ideas like this has saved many a useful thought from being lost to my wandering mind
wait, this is another of those ideas i have that i assume would be obvious but actually aren't isn't it? went to look for plans to make a solar oven/"haybox" combo out of a cooler. why aren't there any plans? seems easy - make a solar oven out of a cooler with a 'solar lid' and then when needed swap it for the insulated lid for a 'thermal haybox' that can also be used on sun-free days. one box, fewer used resources.
the basic thought so far:
cheap cooler with a hinged lid
line the lid and inside with mylar
make a frame to fit the top with a sheet of glass in it
black cast iron pot with a lid. the pot needs to be not too much smaller than the cooler itself to function effectively as a haybox.
a rack to set the pot on to keep from melting the plastic of the cooler
my dutch oven is still too new and grey, needs a few years. i will likely have to buy a preseasoned one or search thrift stores
