Finals, Papers, and Sunshine OH MY!

The final sprint to the end of the semester has begun.  With only a couple weeks of classes left, I am somewhat relieved, while being simultaneously overwhelmed by the amount of work that is piling up.  I have spent the majority of my efforts this week preparing my research paper for S-STEM, and hopefully I will have the paper and the power point done this weekend.  This week we finished the parabolic trough...finally.  Mylar sheeting has been attached to the frame and we are on course for steam generation for the latter part of next week.

Below are a few photos of the parabolic trough, before attaching the Mylar sheeting to the trough.  The process involved with attaching the takes a few days to complete.  Cleaning the sheet metal with acetone was step one, followed by laying down a layer of primer on the sheet metal.  After the primer dries, it is then wet sanded and another coat of primer is applied to the sheet metal.  After a final sanding, the Mylar sheeting can be applied using glue, and a careful hand when applying the Mylar, as it can dull and scratch quite easily.

Concentrate!





This week was another round of exams making life more difficult than usual, but all in all I think everything went pretty well.  I aced my Differential Equations exam and feel fairly confident about my Calc 3 and Physics exams as well.  In regard to my project, I got to use a new piece of equipment called a shearer.  Basically it cuts large sheets of metal into smaller ones.  The sheets of metal cut will make the parabola of our concentrator.  There are a few shots of the concentrator below with no sheet metal on it, as well as a piece of equipment called "Chicago".  Chicago is the shearer that cut our sheet metal like a hot knife on butter.

METS

Lat Friday our special projects class at SMCC took a trip down to ASU to watch a presentation by the METS department.  METS stands for Motivated Engineering Transfer Students.  They gave us a very in depth look at how to transfer properly as an Engineering student to ASU.  Financial aid, scholarships, and application deadlines were all discussed.  If any of my fellow STEMmers are planning to transfer to Ira Fulton anytime soon, I would definitely suggest going to one of these presentations.

This was especially helpful to me, as I just changed my engineering major to Materials Science Engineering, and had a ton of questions about potential new course requirements.  The METS department put me in contact with an adviser for my new major , which has taken a lot of stress off of my shoulders for this next year.

For my project, my team has been incredibly busy and we will be spending the whole day tomorrow finishing our concentrator.  Pictures will be posted sometime this weekend.

More Progress.




This seek we completed the frame for our parabolic concentrator.  Luckily one of the guys on our team is a welder, enabling us to make a metal sub-frame for concentrator.  To do this, we first drew the curve of our parabola on a table.  After the curve was drawn, we then used it as a template to bend the steel rods into place.  Ideally we should have used a tubing bender, but our resources were limited, and we did the best we could with what materials we had.  One of the pictures above shows the "tool" that we used to make our steel parabolas.  To enable adjustments, which will allow us to focus it, we welded little slots onto the steel parabolas.  We tapped the slots, and now using simple bolts we will be able to focus the direction of the parabola in twelve different places.  This weekend we will be fine tuning the parabola, and then we will start on the actual energy generation aspect of this project.
