Just made my first solar cooker, panel style. This is the one I did:
Made it out of reflectix. Weighs 8 oz. Folded down its about 14x14x3. I guess it could be rolled too.
I guess a scaled down, and lighter version, could be made from that windshield reflector stuff. Or same size and use one of those space blankets.
I'm waiting on my antigravity gear pot so I can test it, unless I find something today that I can use for car camping.
Also just made my first alcohol stove, super cat. But that thing needs a stable stand. I know Wood has a design for one on his site, but I might try something else.
