The Sea Cheetah, a hydrogen-powered flying vessel developed by Miami-based startup, is set to revolutionize transport with its concept based on ground effect technology. Powered by hydrogen-fueled electric engines and generating hydrogen locally, it promises fast and zero-emission travel for passengers and cargo. The craft's unique design, featuring a large wing optimized for ground effect with winglets for stability, poses as a disruptive innovation in the shipping industry. The Sea Cheetah's regulatory classification as a ship in the US accelerates its commercial rollout by circumventing lengthy aircraft certification processes. However, challenges like stability during flight due to swells and integration into maritime traffic raise concerns, necessitating advanced collision avoidance systems to ensure safety. Despite obstacles, the Sea Cheetah faces competition from other ground effect aircraft like the Viceroy Seaglider in the zero-emission transport market, highlighting the industry's shift towards sustainable air and sea travel. Ground effect technology, which boosts lift and reduces drag for increased energy efficiency, underpins the Sea Cheetah's promise of efficient, long-distance travel with minimal fuel consumption.
