I am creating a solar water boiler. The max dimensions are 1meter diameter. What I would like to do is create a giant parabola with water can at its focus point. Unfortunately, I need to brush up on my parabolic knowledge. The parabola should be as wide as possible in order to capture the maximum amount of sunlight but the focus must stay within 1 meter of the origin of the parabola. Anyone want to run me through first few steps?
Thanks a bunch
