Scanning electron micrograph of Salvinia natans,showing detail of the hydrophilic tip (brown) on top of a trichome. This floating fern plant has superhydrophobic hairs (trichomes) on the upper side of its leaves. Each of these eggbeater shaped hairs exhibits a hydrophilic tip on top of each hydrophobic hair. The combination of a hydrophobic surface with hydrophilic tips is called the "Salvinia Effect". These air retaining surfaces are of great interest,particularly with fuel consumption when applied to ships having to overcome friction produced by the drag of water on their hulls. This drag could be reduced dramatically with the "Salvinia Effect",a layer of air between the ship's hull and the water,saving vast amounts of fuel. A suggested estimated saving of 20 million tons of oil per year for just a 10% decrease in drag for shipping alone. Magnification: x7320 (x1800 at 10cm wide) | |
