Shark-skin is an effective way to move in liquid.
As proven by scientific experiments, this surfacing helps sharks achieve immense speed and acceleration in water. Reseach has been made as for how to apply this surface to modern applications.
It’s all based on its hydrodynamic shape.
The dents have real smooth surfaces with minimal friction.
In addition to, the base of the dents contains hydrophobic material that does not allow water (liquid) particles to enter.
Its industrial, simplified version is much more probable for an industrial or commercial application.
Its shape is much more simple, yet holds the same key design language.
Trials have been made for surfaces of trains and ships.
The problem up to this day remains the high cost of the application, even though it is slightly balanced by the fuel consumption saving.
