Which outcome impairs ship engine efficiency when scaling geographically?

💡 Explanation

Elevated seawater temperature reduces the temperature difference in the Carnot cycle, therefore decreasing engine efficiency because the thermal efficiency depends on the temperature gradient, rather than improved combustion or compression that would aid efficiency.
