Solar cooker

thingiverse

The solar cooker designed for my Calculus class features a paraboloid generated by rotating y=0.8x^2 around its axis within the bounds [0, 0.25]. It includes one full 18-degree slice for printers with large print areas. For those with limited printing capabilities like myself, slices can be divided into two pieces to assemble later. This project requires dedication; it entails printing 20 slices for a complete paraboloid. However, fewer slices can suffice depending on the reflective material used. Ensure your chosen reflective tape adheres well to the plastic you use and print at the lowest density possible without altering the upper surface's shape, as this is crucial for functionality. The paraboloid's design allows it to focus light parallel to its axis onto a single point - in this case, 31.25 cm above the center of the cooker. This concentration of energy enables cooking tasks like marshmallow roasting. If you try this solar cooker, kindly share your experience.
