“The material covered in LSSU's engineering program provided me a solid foundation for graduate studies. The systematic approach and communication skills needed to tackle engineering projects were taught and then practiced over and over again. In particular I appreciate the many hours spent by the faculty to develop oral presentation skills in each student. As a graduate student now, these skills have proven to be highly beneficial and, to my surprise, obviously not taught to the same extent at many other universities.”

Project Description:Vehicle Dynamometer Testing System


Donors & Technical Advisors: Revolutionary Engineering, owned by LSSU Alums Dan (’92) and Allen White (’95), and engineer Matt Slaght (’07)

The main objective was to create an instructional test cell for evaluating automobile performance to be used by the vehicle systems option students. The test cell controls a dynamometer via computer to record the torque, speed and horsepower of a vehicle. Team GLDS refurbished the system and restraints, and developed the safety systems. Additional instrumentation may be interfaced with the work cell to measure the vehicle’s emissions and vibrations in a controlled environment. The dynamometer and test cell are unique to this region and can serve to benefit the community.

Alternative Management of Anaerobic Landfill Bioreactors for Improved Energy Potential

Josh Kuzimski

Converting municipal solid waste to usable energy is an emergent and growing method for modern waste management. Through microbial facilitation of methanogenesis, methane gas can be extracted from landfill bioreactors to yield a significant amount of usable energy. The hypothesis was that a sufficient addition of sodium acetate to a controlled bioreactor environment would promote larger growth of methanogenic microbes and subsequently promote a greater amount of methane relative to a control (Madigan et al, 2003). In order to simulate an anaerobic bioreactor environment, the method for the study took place in modular sections to cover the design, construction and operation of laboratory scale bioreactors. Upon completion of bioreactor engineering, the biological and chemical components were scrutinized to match ideal conditions of a landfill. Methanosarcina was the chosen genus of the methanogen family to seed the bioreactors, and a total elemental analysis of the waste source was analyzed to approximate methane yield. Over 557 hours, each bioreactor produced approximately 1.3 liters of biogas with less than 1% containing methane. Given analysis through gas chromatography, the bioreactors may have had stunted methane production do to presence of argon gas in the headspace and/or low C/N ratio of the waste. The presence of argon should have been replaced with nitrogen, and the waste source should have contained more carbon per nitrogen. The generation-3 design of constructed bioreactors was successful in containing all gasses, liquids, and solids internally, however did not produce enough methane biogas to accept or reject the hypothesis.
