temperature (and with that performance)of solar modules, is the airflow around them. With only average daily and not hourly wind data available from anearby town, this data may only be used to verify a visual trend of any impact stronger winds may have onmodule temperature. Figure 4 gives an example of this data, the trend-line creating a very clear divide on highinsolation days, between higher winds (red- above 2.65m/s) and lower winds (blue- less than 2.65m/s).This didnot hold up for some other months, as seen in Figure 5. While seemingly random, all high winds for themonth(>=3m/s – Figure 6) did correlate to lower temperatures (though not vice versa). This is expected to bedue to the necessity for much stronger winds in order to cool the

students.IntroductionAccording to the National Science Board (NSB)’s Science and Engineering Indicators 2004,enrollment in undergraduate engineering and science programs in the United States has been indecline since the 1980s1. Clearly, there is a continued need for increased enrollment andretention in science and engineering. Science, Technology, Engineering, and Mathematics(STEM) have become increasingly central to our economic competitiveness and growth. Long–term strategies to maintain and increase living standards and promote opportunity will requireunprecedented coordinated efforts among public, private, and non-profit entities to promoteinnovation and to prepare an adequate supply of qualified STEM workers2.The MSETI - AREA project utilizes an undergraduate

28 mph (12.5 m/s) and astart-up wind speed of 7 mph (2.7 m/s). The aluminum body houses an accurate heading anglesensor (in-house modification) and a generator with charge regulator that produces 12 VDC forcharging batteries. A cup-type wind anemometer, wind direction vane, and a shielded thermistorare also mounted on the mast. Outputs from the DC generator and all sensors are routed to a dataacquisition panel located in a laboratory classroom. The panel displays DC voltage, DC current,wind speed, and temperature with outputs for load connection and analog outputs for computerdata logging of all sensor outputs. Students record data during a 2-3 day windy period and thenreduce the data to yield a power curve that is compared with that of the

of the practical. Surveying commercial applications would help, too. (The professor)'s experience and stories of how things are really done was of great value. I wish more courses would tell students what it is really like out there. I use this aspect of the course when writing cover letters or talking to recruiters. • The course required a lot of research and creativity because the subject material is not frequently touched upon by many classes. • I thought that this course challenged me to think a lot more than most other courses at this level. I loved the concept of actively coming up with a new solution to problems in our assigned fields. I loved this creative aspect of the class and feel it was

This came in response to the question “which of thefollowing alternative energy sources…hold[s] the most promise in easing US dependence onfossil fuels over the next ten years?”6 Within the responses, hydropower also received negligibleresults. A couple of important differences to note were that nuclear energy was not listed as itsown
