While the idea of an edible airplane is purely fictional, the real energy potential within an aircraft is astronomical. A single US gallon of jet fuel contains approximately 34 million calories, meaning a large passenger jet like an Airbus A380 carries over 2.8 trillion calories in its fuel tanks alone. The question 'how many calories are in an airplane' is a fascinating thought experiment with a very real, and massive, energy-based answer.

This statistic hints at the complex ways transportation relies on water, encompassing everything from maritime ballast to the vast, indirect consumption tied to fuel production. So, how does transportation use water and what is its true impact?
