The discussion revolves around the concept of increasing wing surface area to enhance lift while minimizing drag. The idea of using pores or corrugations on wings is explored, but it is clarified that such modifications may not yield a net gain in lift due to the counteracting forces involved, ultimately leading to increased drag. The conversation touches on the complexities of airflow dynamics and the role of wing design in managing pressure differentials, emphasizing that larger wings are a more effective solution for increased lift. Additionally, the importance of understanding aerodynamic principles, such as Bernoulli's principle and Newton's laws, is highlighted in relation to airflow behavior over wings. Overall, while innovative ideas are discussed, the consensus is that increasing surface area without added drag is challenging.
