[QUOTE="archive10, post: 991025"] Just curious - a lot of discussion on this forum relates to parabolic antennas tracking the sat arc. How do you get the reflector of a sun-cooker to track the sun when you need to cook anything that takes more than a couple of minutes? And how do you control the temperature of the cooking vessel? Do you only cook stuff that boils in water? As an academic contemplation, I can see a "stove"-mount that tracks the sun (probably a computer controlled El-over-Az mount), with a pot hanging from some suitable arrangement allowing it to be moved up and down in the focus, giving control of more or less sunlight/cm2 to adjust heat irraditation. And of course a short-time mechanism to compensate for clouds etc. Now there's a challenge for the polar mount builders of this site... :) [/QUOTE]
