Nice! Please keep us updated. I'm interested how your project will sail smooth too!
Will prolly depend upon the materials you choose. Mine is intended for shorter trips and is not collapsible, but can be used for storing stuff while not in use.
I'm almost finished with it but need to test it for quality.
If it works, I will show you.
I made the glass out of 3 layers of 5/16 strata glass. Strata glass is a more scratch resistant glass. The best they make I think. I used 3 layers for the weight. Prolly two if it's 3/8ths.
Then I trimmed the glass with that foil tape. Next I'm going to put thin black rubbery foam to help it seal.
Painting the inside of the cooler black this am, and applying the foil tape to the inside of the cooler lid.
Then comes the test. Does it work? how well? will it boil water? Bake bread? How long will it take? etc...
