The article describes a student project of installing a micropower generation system utilizing energy from the water drained from underground coalmines. The paper contains a description of the site which is a manmade phenomenon from the anthracite mining era. The project described in the article was completed as part of the project-based learning curriculum. Students had the opportunity to work on a team and apply theoretical knowledge learned in individual courses as part of the engineering curriculum. The article also focuses on the calculation of the potential power capacity to a proposed hydropower generation system. The proposed micro-hydro system is harvesting the potential and kinetic energy of the water discharged from the water-draining tunnel. A commercially available micro-hydro turbine combined with an electric power generator was adapted for this purpose. The article also includes an analysis of the profitability of the project and the time of return on investment. The calculations are based on the current price of electricity (2021), depreciation schedule and present tax incentives (2021) to generate electricity from renewable sources. The article also includes some lessons learned from the project as well as the recommendations for future projects.

The article describes a student capstone design project completed by a team of five students and implemented by a resort and casino in Northeastern Pennsylvania (NEPA). This project was completed within the framework of project-based learning (PBL). Students had the opportunity to apply the knowledge that they learned in the classroom in a real-world application. Students also had the opportunity to work as a team which was supervised by the faculty. The outcome of the project provided valuable experience in creating of grid, a reliable source of energy. The heat generated as a by-product was used for the purpose of heating hot water and a swimming pool as well as space heating for the hotel and casino during the winter. In the summertime the excessive amount of heat was used to dehumidify the air in the hotel and casino. Dehumidifying the air increased the level of comfort in the hotel and casino as well as in the enclosed swimming pools area. The article is focusing on the cost effectiveness of the off-grid heat-and-power solution. The net present value and internal rate of return as well as the payback time were calculated.

The publication focuses on assessing the energy efficiency in residential and to some extent commercial applications. An energy audit is always the first step in addressing energy efficiency. The purpose of the publication is to present the benefits of using an energy audit. It explains a “do-it-yourself” procedure for an energy audit. The publication also focuses on calculating the potential energy saving by updating low-efficiency electric appliances with high-efficient alternatives. The environmental benefits of addressing the energy efficiency of households is also being discussed. An energy audit using a “do-it-yourself” procedure focuses on the economic, ecological and social impact to environment. The energy audit contributes to the implementation of the concept of sustainable development in our day by day life.

Purpose: The aim of this paper is comparison of the Curriculum of Mechanical Engineering Program in Poland and the United States. One of the institutions is The Pennsylvania State University (PSU), in the United States (USA). The other institution is Politechnika Opolska (PO), in Poland. Design/methodology/approach: Desk Research Method is used. Paper is based on Politechnika Opolska’ documents and The Pennsylvania State University’ documents. Findings: The paper addresses the similarities and differences in both curricula. It also addresses the positive and negative aspects of both curricula. The strengths and weaknesses from the perspective of the future career development of graduates is also being addressed. Both Mechanical Engineering programs are striving for excellence in preparing students for engineering jobs in industry, but the philosophy of those programs is very different. The Mechanical Engineering program at PSU is providing the student with a stronger theoretical background. Graduates from the PO program are well-trained in application-focus current industry practices. They are not going to require on-the-job training after entering industry. There are also suggestions and recommendations for both programs from the perspective of identifying the best practices. Originality/value: The article contains a comparative analysis of the curricula of the Mechanical Engineering program at The Pennsylvania State University USA and Politechnika Opolska, Poland. The comparison of the curricula was done using the most recent catalogs of both programs. The authors of the article have had experience as faculty at their respective programs. The comparative analysis was done for the purpose of identifying the best practices and subsequent follow-up. The article addresses the similarities and differences as well as the strengths and weaknesses of both programs. The article also contains suggestions and recommendations for both programs.
