We conducted finite element simulations using COMSOL Multiphysics to analyze thermoelectric generators (TEGs) placed between a warm surface and cold deep seawater channels under different operational conditions. The research examined parallel and counter flow configurations at Reynolds numbers between 3987 and 73,800, with channel heights varying from 0.002 to 0.072 m. Results indicate that Reynolds numbers above 12,000 ensure stable heat supply to TEGs, resulting in a consistent output power of 3.01 W. The optimal net power of 1.45 W was attained at a channel height of 0.002 m, attributed to reduced pump power consumption. A comparative analysis of Bi2Te3-based material combinations demonstrated that improved electrical and decreased thermal conductivity notably enhanced system performance. This study offers essential insights for improving the design and implementation of TEG-OTEC systems, especially in offshore contexts where operational efficiency and system durability are critical, thereby contributing to the advancement of sustainable ocean energy technologies.

It highlights Taiwan's integration of AI into biodiversity monitoring, underwater exploration, and environmental analysis, while addressing legal challenges in intellectual property, data protection, and national security. A governance model was developed to enhance the legality, security, and credibility of marine datasets through data collection policies, legitimating measures, and inspection protocols. Comparative insights from the EU, United States, Japan, and Korea stress the need for Taiwan to refine AI policies, strengthen cross-agency coordination, and align with international frameworks, particularly the UN Sustainable Development Goal 14 (SDG 14) and the Ocean Decade. Taiwan's experience provides a replicable prototype for emerging maritime AI nations, linking innovation with legal compliance and sustainable ocean governance.
