This study presents the design, development, and experimental evaluation of the BCEE – Biomimetic Wind Energy Capture System, engineered to enhance the efficiency of small-scale wind energy conversion within the context of local sustainable development and the 2030 Agenda (SDGs 7 and 13). The research is grounded in a comprehensive theoretical review of global climate change, the role of fossil fuel-based energy systems, and the technical limitations of currently available small wind turbines. This led to the adoption of biomimicry as the guiding principle for the geometric and functional design of a new wind energy collector. The BCEE system incorporates a cylindrical casing with internal and external deflectors and a multi-blade rotor, whose topology was iteratively refined through a sequence of laboratory learning tests aimed at identifying the most efficient configurations for wind redirection, blade count, and deflector arrangements. Experimental investigations were conducted in a dedicated laboratory environment using a wind tunnel, anemometry, and electrical measurement instrumentation, comparing two BCEE prototypes (cm and cm) with state-of-the-art vertical axis wind turbines under controlled wind speed regimes. In all comparative trials, the biomimetic prototypes demonstrated substantially higher conversion efficiency than reference systems with similar characteristic dimensions, evidencing a significantly improved capacity to extract kinetic energy from the airflow under the tested conditions. The results corroborate the technical feasibility of the BCEE concept and its potential as a distributed micro generation technology compatible with the requirements for clean, decentralized energy solutions suited to local contexts, reinforcing its relevance as an innovative contribution to the advancement of wind energy systems aligned with sustainable development goals.
