The article discusses using tidal current power technology in cooling water channels in South Korea to generate clean energy. The researchers conducted experiments in a circulating water channel to study rotor design, floating body stability, power delivery, and device maintenance. They found that the high-speed discharging water in the channels can be harnessed effectively for power generation without significant variations in speed or direction. This approach could help maximize the utilization of clean energy while minimizing environmental impact compared to traditional tidal barrage systems.
