This  past semester, the concentrated cooker sub-team has spent much of it's  time researching past successful parabolic cookers and both designing  and constructing its own concentrated cooker. Past teams' attempts at  building non-conventional box-cookers have been relatively unsuccessful.  Therefore, our team's goal was to build a parabolic cooker that  effectively reached high temperatures of 250 degrees Celsius needed to  fry tortillas (a staple food in Nicaragua).
\\

We used a "petal" approach to build the reflector. We cut multiple  petals into a flat aluminum metal sheet, curved each petal upward and  overlapped the edges to form a parabolic surface. Each petal was adhered  together using reflective tape. After the paraboloid was completed, a  wooden framing system was built to support the reflector. The framework  was designed so that it could tilt the parabolic cooker to directly face  the sun at any angle in the sky. In addition, the support system is  mobilized on wheels so that it can rotate a full 360 degrees.
