Yesterday, I set up the aluminum pipe again since the last experiment was not accurate in the sense that we had an air gap in the pipe due to the fact the wax was filed with bubbles in there. We should avoid the air gap while filing up the pipe because this case slows the temperature change process.
Today I will try the experiment one more time and see.

yesterday, I did the experiment using the aluminum pipe filled up with wax and the result is shown on an excel graph.
The first solar intensity measured was found to be w/m^2 at 11:28 am. Then at 11:45, it went up to 1302 w/m^2.
The support structure was adjusted at 11:32 am. The intensity went down to 590 w/m^2 at 11:45 am, and again the support structure was adjusted at 11:58m.The intensity was measured again at 12:00 pm 1410 w/m^2 and 1210 w/m^2 at 12:06 pm.The support structure was adjusted at 12:24 pm.
I just want to let you guys know must you can find graph on goggle drive as well. Thank you.

Yesterday,I set up the aluminum pipe by filling it up with wax and I sealed it. Now I just have to wait for a nicer day to perform the next experiment.

Today the weather isn't with us, so instead we are helping are classmates in the block house project.
However, here are some pictures from last week's experiment

Yesterday, we drilled a hole on one cap of the aluminum cylinder and we sealed that end with silicon. We weighted the pipe.
Today, we are performing our a new test.
11:14:45 AM 1225-1230
11:27:26 AM 1280-1287 The sun intensity was different where we were, so we moved the solar concentrator to the area where there was greater intensity.
11:42:15 AM 590-610 There is a cloud under the sun, and the instrument is showing around a 50% difference in sun intensity.
11:45:44 AM We adjusted the solar concentrator
12:00:43 PM 630-650 Cloud is still over us.
12:10:55 PM The sun is being covered by long low clouds, which are covering at least 70 percent of the sky. This experiment shows how the solar concentrator does with partial sun exposure. On the field we noticed that the temperature of the center thermal sensors continue to increase at a steady pase, but not as quickly as when we had full sun exposure. However, seeing the steady increase of the temperature without having a medium inside the center cylinder is promising. Once we have a medium inside, it should show even more retention and continues increase.
12:13:19 PM 620-650 The temperature has started to go down. Thus we hypothesis that the reserved heat has broken even, and with no reserve it has started to lose its previous rising slope.
12:19:39 PM 750-780 We are experiencing temperature fluctuation now, since the sun is coming from under the clouds, but as the wind blows it changes our temperature variables. However, the temperature is back to rising steadily, but slowly.
12:24:08 PM 1100-1121 The sun is now is almost at its center point, still partially covered, but the temperature is rising steadily.
12:28:47 PM 1312-1315 The test shows that the temperature is rising steady and that if we were cooking something it would slowly cook. Our empty cylinder is not letting the heat escape and is slowly absorbing the heat.
12:30:52 PM 1412 mark 421
12:32:18 PM 1330 mark 424
12:34:22 PM 1412
12:34:42 PM 1430-1440 mark 450
Final notes Jun 25, 2015 This experiment was done on partial sunny day with no medium inside the aluminum cylinder within the solar concentrator.
Today, we are performing our a new test.

Yesterday was not as successful as we hoped. Our experiment with the wax proved to be a runny one. The waxed leaked from one of the ends of the cylindrical pipe. It was quickly noticed since the temperatures in the thermometer started to fluctuated once the wax leaked.
Today, since it is gonna rain and our materials aren't here, we are gonna help in other projects we are involved in.

Last Thursday we set up a phase change material using a pipe filled up with wax and sealed both ends.
Today we will try our second test.
The second test was not a success since there was a lick on one end of the cylindrical pipe. The reason is because the red silicon applied to seal both ends did not hold. The temperature went up too fast after 300 degrees Fahrenheit because of the wax melting out of the pipe and accidentally increasing the temperature out of the pipe. Hopefully we try something better with the aluminum pipe.

Yesterday, we did a lot of work with the solar concentrator experiment. we started tracking the sun light intensity in order to orientate the solar concentrator structure. We had to set up the temperature reader device plug thermocouples, and the SD card; then we mounted the glass tube. We started recording measurement until we almost the maximum temperature of the glass tube. At the end we made our excel graph

Yesterday we worked on reading one of the papers professor gave us.
- Review on thermal energy storage with phase change materials and applications by Atul Sharma, V.V. Tyagi, C.R. Chen, D. Buddhi
Today's Goal
- To produce a data plot of the solar hot dog
Notes for the future:

- Ambient temperature

__________________________
Experiment 1 Data- Testing the hardware
Solar intensity at the beginning 1230 w/m² (11:00 am)
Solar intensity
- 1228 (11:20 am) (set up)
- 1257 (11:35 am)
We adjusted the solar concentrator at 11:30, 11:32, 11:35 to get a better focus point. This might be seen in the data.
We notice the focus point on our hot dog solar cooker is a bit off and we are not getting the best possible focus on the cylinder tube. We might need to rethink the angle or redesign the solar concentrator.
Notes for the future:
- A tube to block reflected light and get a more accurate light intensity reading is needed.
- Metal Clips are need to be made to keep the thermocouple wires in place
- An thinner aluminum tube is needed to house our medium. Our current metal tube is too thick

During our meeting with
Professor Sivo we discussed the process of using wax as an organic
battery to collect the thermal energy from the solar concentrator. As a
result, we researched different types of wax and examined their melting
point to see which on fix our criteria.
After examined the following types of waxes.
We determined that beeswax will be our mostly likely candidate for our first prototyped.
Since we need to work with Fahrenheit, we reset and retested the (name the instrument, add a picture). Our excel data collection is working properly as of right now. To protect the sensitive thermocouples, we looked into thermal casing. Our chosen medium is red silicon tape or their silicon sleeves.
We also research 1ft threaded pipes, but found none with such dimension. We will continue to look into this.
Here are some information about the 1 foot pipe as needed
As part of our research, we watched various videos on how to make a parabola mold out of concrete. This mold is later used to created the parabola shape with fiber glass.

Today we are working on all the reading material provided to us by Professor Sivo.
After examined the following types of waxes.
• Natural Wax
- Beeswax: Melting point 142°-150°F.
• Synthetic Waxes
- Microcrystalline wax: Melting point is approximately 160°F.
- Paraffin wax: Melting point 135°-140°F.

Yesterday, we discussed with Dr. Sivo ways to design the parabola and how to perfectly locate the focal point.
we went over equations but still the idea is that we will start with a satellite dish miniature version for our first attempt and then we will scale it in the future on the big satellite dishes.

Yesterday, we had to set up a plan with all the steps necessary to construct the parabolic shape of the solar concentrator.
We chose to build one instead of using a satellite dish, and the first step is to be able to write the equation of the parabola and then find the best location of the focal point using a mathematical model.
Today we will start with the theory on this project and Professor Sivo and I(team leader) will be working on it the get the conceptual approach of what the construction is about.

Yesterday, we did studies on solar concentrator and end up deciding to start with a satellite dish just to see how it works and then scale it to a larger parabola dish.
we contact DPW Saddle Brook and the STC department at BCC to find out if we could get one free, it was impossible. We still trying. On the other hand I spoke the stem coordinator Luiz Deabreu about a possibility of getting one cheap from one of the BCC partners.
We sent to Eric all the info about the project(member, team leader, meetings frequency, and faculty involved).
