Design and fabrication of a demonstration model for promoting low-carbon energy technologies

Abstract

This article presents the design, construction, and educational application of a large-scale model representing renewable energy facilities that do not yet exist. The model features a circular layout with a diameter of 2 meters, divided into two halves: the Mokrice Hydropower Plant and a nuclear power plant with an accompanying low- and intermediate-level radioactive waste repository. The Mokrice half highlights key ecological and technical features, including two fish passages and a solar power plant installation, with realistic water effects achieved using epoxy resin. The nuclear half includes a removable low- and intermediate-level radioactive waste repository, allowing viewers to explore storage arrangements via a cross-sectional view. All components were fabricated using FDM 3D printing, assembled, finished with paint and landscaping materials, and mounted on a wooden base with a metal support structure. While the model was not intended to achieve exact technical scaling, it effectively communicates complex energy infrastructures, facilitating public understanding, awareness, and dialogue about low-carbon technologies. The combination of additive manufacturing, interactive features, and detailed landscape representation demonstrates the value of models as tools for education, demonstration, and the promotion of sustainable energy solutions.
