A method is provided for preserving live bacteria by subjecting an aqueous system containing the growing bacteria to drying without special equipment, in the presence of trehalose with or without the addition of divalent cations as stabilizing agents. The fairing element includes a lower support surface extending beneath the body substantially between the extremity of the motor vehicle and the motor-vehicle member along a negative incline, such that the low point of the lower support surface is lower than the low point of the motor-vehicle member along a vertical axis of the motor vehicle. The method also includes identifying at least one alternate source of power for the at least one zone, identifying at least one switch within the power distribution network capable of supplying power from the at least one alternate source to the at least one zone, and generating a restoration plan for restoring power to the at least one zone.
