The speaker mentioned that one advantage was that it was not a coating, the
refore would not wear off. That got me wondering if the etching could event
ually get filled up with minute particles of dirt. Perhaps the etching is s
o small that nothing (yet) could fill the spacing. He did use the terms mic
ro and nano scale, so perhaps that is not an issue.
The water repelling (and self-cleaning) behavior requires the aid
of gravity. That means a flat surface will still collect water and
If the surface is tilted with respect to level, as the water washes
the surface, it takes dust with it. The advantage of this surface
treatment is that the tilt needs to only be a couple of degrees,
vs. thirty or more for standard water repellant surfaces.

Why would there need to be a flat surface within the contained space? Angle everything and continually rotate the space.
Here's my plan: Use the energy harnessed from the continually bouncing water to provide power to the motor that rotates the space.
Perpetual Motion! ;-)
Given how long it takes to do a square inch, a boat hull may be a few
years away 8^)
Now if they could get it to shed water in a preferred direction, a self
propelling boat would be kinda cool,
