For decades researchers have been trying to create this incredible vehicle, but with little success, Harvard University reported. The largest challenge has been a serious conflict in design requirements: aerial vehicles require large airfoils such as wings or a sail, while underwater vehicles need to minimize their surface area to reduce drag. To solve this problem, a team of research took inspiration from puffins, which use similar flapping motions to propel themselves through both the air and water.
