How To Fly More Fuel-Efficiently

The video discusses the significant energy consumption and climate impact of aviation, highlighting that even small efficiency improvements can have a large effect. Engineers are drawing inspiration from nature, such as sharkskin and geese, to reduce fuel use. Sharkskin-inspired coatings reduce drag, while formation flying mimics geese to save fuel. These innovations, along with others, have significantly improved aviation efficiency since 1970. The video emphasizes the importance of continued efficiency improvements as air travel increases.
