Young University (BYU) are developing extremely waterproof
surfaces that they believe could dramatically improve the efficiency
of both power plants and solar energy systems. These surfaces, called
superhydrophobic surfaces, are extremely difficult to wet since they
cause water to aggregate and form beads that sit on the surface.
you turn to nature you can see numerous examples of naturally
occurring superhydrophobic surfaces such as duck
feathers, butterfly wings and lotus leaves. These surfaces
efficiently repel water, causing it to clump together and form little
beads because it is more attracted to itself than the surface. These
surfaces have inspired many engineers in the field of biomimetics,
where scientists attempt to imitate elements of nature to solve
problems. Read more.
