Abstract
This research paper explores the lifecycle assessment (LCA) and techno-economic assessment (TEA) perspectives in depth while analysing power-generating bearings. Power-producing bearings are novel parts whose purpose is to capture mechanical energy wasted in friction and transform it into useful electrical energy. These cutting-edge bearings offer a viable path towards sustainability and energy economy in a range of mechanical systems. The research work provides an overview of the basic ideas behind power-generating bearings, including their construction, working principles, and their uses in a variety of sectors, including renewable energy, aircraft, and the automobile. Subsequently, the life-cycle assessment (LCA) is used to appraise the ecological consequences linked to the complete lifespan of these bearings, encompassing the extraction of raw materials, their production, operational utilisation, and eventual disposal or recycling. This evaluation offers a comprehensive picture of the sustainability credentials of power-generating bearings and highlights important environmental hotspots. In addition, the TEA provides an economic viewpoint by evaluating the expenses and viability of funding related to the creation, manufacturing, and use of these bearings. Cost analysis, market possibilities, payback times, and economic advantages over traditional bearings are all included in the TEA. In order to give stakeholders a comprehensive knowledge of the investment and economic return, it looks at a variety of economic possibilities. This research work gives a comprehensive study that illustrates the advantages of power-generating bearings for the environment and the economy by merging LCA and TEA. It also helps identify options for optimisation and development. The knowledge gathered from this comprehensive evaluation is essential for directing future studies, creations, and applications of economically viable and environmentally friendly power-generating bearing technologies.
