If Leif is right in that it will eventually have triple the energy density and stiffness, it might become really useful for electric powered flight. You want to be in a situation were having isolated internal supporting structures made of batteries is enough. With the current specs you'll probably have to replace every single structural component with batteries. Even that might not do it.
