Description
1:00 IMPROVEMENTS AT THE WEST GEORGIA OBSERVATORY, Bob Powell and Robert Moore, Jr., University of West Georgia, Carrollton, GA 30118. An on-campus observatory was opened at the University of West Georgia in October, 1979. The five-meter dome housed a 14-inch Cassegrain telescope, purchased with a National Science Foundation Grant for Instructional Scientific Equipment. During the last 29 years, the observatory has been used for astronomy class and laboratory observations and student projects. Regularly scheduled public observations have brought thousands of people to the facility. School classes and clubs as well as civic clubs and church groups have arranged visits to the West Georgia Observatory. Even though the sky now has severe light pollution, a campus observatory is needed for the convenience of students. In October 2008, a 16-inch Meade LX200 Schmidt-Cassegrain telescope was installed in the facility. This computer-driven scope enables the operator to locate dim celestial object more easily. In addition, an Orion StarShoot Pro Deep Space Color CCD Camera was acquired. This camera has a 1.8-inch format CCD with a 3032x2016 pixel array with thermoelectric cooling in the camera to reduce thermal noise in the images taken. Exposure times can be varied from 0.002-second to 9.5-hours. Despite the light pollution, good photographs are being taken of celestial objects, such as the Ring Nebula (M27), the globular cluster in Hercules (M13), and the Orion nebular (M42). The new telescope and camera will allow more students to complete projects. 1:15 PRELIMINARY STUDIES OF PRODUCING HYDROGEN FOR A FUEL CELL, Raymond Hill, * Austin Kerlin, * Benjamin Jenkins,* Robert Moore, Jr. and Bob Powell, University of West Georgia, Carrollton, GA 30118. Students are interested in alternative energy projects. This research group selected a project to generate hydrogen to operate a fuel cell. Work has been completed on two aspects of the project. A device has been constructed from stainless steel to electrolyze water. Studies have been completed to optimize the efficiency of this apparatus and to reduce contamination of the hydrogen produced due to unwanted reactions between the electrolyte solution, conductor plates, and wiring of the apparatus. Studies have also been conducted on the production rate of hydrogen gas as a function of electrolyte concentration and the number of electrode plates The second part of the study involves the usage of a solar panel to produce electricity for the electrolysis. Studies have been completed on its output in regard to the orientation with the Sun. Usage of lenses or mirrors to concentrate the radiant energy is being conducted. Electricity from the solar panel will be used to generate hydrogen via the electrolysis of water in the next phase of the project.
