A cardboard prototype of the trough was assembled to evaluate the construction of a trough, test the efficiency of an imprecise trough, and test the overall feasibility of a trough. The frame of the trough is constructed of cardboard sections fitted together. The trough is 40 inches long and uses the solar trough parabola and a ¾” steel metal rod for the receiver.

Subject Matter Expert Review

Dr. Stevens viewed the parabolic solar collector favorably. He confirmed that it should be able to produce steam at the rate we were seeking. He found few concerns with collector itself, though he did voice some initial concerns over the solar flower’s tracking mechanism and the method to circulate water through the distilling system.

Photovoltaic Backup

Prior to proof of concept analyses, the team was unsure of the solar trough’s ability to produce steam at the required rate. In order to mitigate detrimental impact on the project, the team chose to develop a design and BOM for a photovoltaic sub-system as a “plan B” to implement into the distiller design if the trough is shown to be infeasible.

McMaster-Carr Purchase Parts

Above is a PDF version of our teams personal Bill Of Materials and Budget Tracking Spreadsheet. The spreadsheet is conditionally formatted to highlight parts that we can potentially get for free, as well as once a part is purchased, it automatically subtracts the cost from our remaining budget. It updates automatically from conditional formatting, drop down lists, and if statements. At the bottom of the sheet estimated cost and remaining budget are both shown.

We've also decided to separate out parts by vendor. The majority of our purchases will be in store pick ups, but we do have some parts that are purchased online and need to go through a formal RIT purchasing process which requires parts to be separated by vendor. The "McMaster" link shows how these will be formatted, and contains all of the parts which will be purchased from McMaster-Carr.

Risk Assessment

Risks

Above is a PDF version of our current working Risk Assessment/Mitigation Document. This document highlights rows green if a mitigation plan has been implemented which decreases either the severity or likelihood of the risk. The summed importance of our risks before and after mitigation are shown at the bottom of the sheet.
