Solar Cooker Update

After taking a break from solar cookers, we got back into it. Benjamin, one of the others in my group, brought it home and finished the main construction. So far we have a fresnel lens on two legs with notches to adjust height. Two weeks ago, I went outside during fourth period after finishing a test, and the wind had knocked it over. Then someone else outside came over and picked up the lens and started burning a wooden stick. It caught on fire, and there's a pic below. I readjusted the cooker after sixth period Kyle, the other group member came to me and told me that it had burned the other piece of wood I placed inside of the pot beneath the lens at the focal point. Now the only problem we have is finding out how to make it wind resistant, and focusing the focal point onto the pot when lying straight. We've gotten to around 175ºF, and we're aiming for about 200ºF-225ºF. We'll get that working and I'll update later.
