Perhaps, it is there that we will begin to solve some of the problems that have plagued man since the dawn of the Industrial Age. We are now in the beginning stages of developing the basic science that can turn ordinary materials into extraordinary materials of great value. This is how finally we can maintain the health of Planet Earth, and meet our most basic needs.
Nanotechnology with all its promise and all the hype will likely
be used first to make promising new materials. Perhaps, one of the
scientists at Argonne will discover the ultimate material, the Golden
Fleece of Materials Science – a substitute for purified silicon made
from ultrathin amorphous oxide and a superior semiconductor.
We
could never solarize the world with expensive and highly purified
silicon. This material is rare and comes from just a few places on
earth. There simply is not enough to go around, but there may be a
substitute that is becoming available to us now with advances in
materials science taking place at Argonne – ordinary amorphous glass.
Ordinary
amorphous glass can be thought of in terms of the din of traffic noise
– an irritating jumble of confused and random structure. Semiconductors
on the other hand are really quite ordinary except that the structure
of ordinary material is rearranged into a symphony of great beauty.
These are akin to nature’s fine crystals formed under great heat and
pressure, and some of the most precious and valuable of all earthly
things as valuable to us as gold.
The future of
the semiconductor industry probably does not lie in bulk
semiconductors, but more likely in ultrathin oxides between ½ nanometer
and five nanometers in thickness. These oxides because of the
transition into the dimensions of the quantum realm below nine
nanometers, begin automatically to take on a crystalline
structure. These are more akin to semiconductors than ordinary
amorphous or non-crystalline oxides. It should only be a simple and
intelligent manipulation to purify these materials and add the impurity
atoms to these ultrathin oxides in order to make a tunnel glass.
In
an electron accelerator, we acquire energy from an electron by
accelerating the electron. At high velocity, electrons gain energy.
There is however another way other than a massive accelerator to
accelerate the electron.
Scientists have been
aware for many years that an electron tunneling or accelerating into a
vacuum gains energy. Instead of using a massive electron accelerator,
we could use the science of Nanotechnology to construct a tiny sphere
of tunnel glass from ultrathin oxide in order to accelerate an electron
and derive useful energy from it. Any vacuum, no matter how pure,
contains some errant atoms and this may be one method of tapping the
elusive zero point electromagnetic field.
The
universe is indeed postulated to be in the form of a polarized vacuum
in the shape of a sphere, and experiments are ongoing to validate this
hypothesis. Perhaps we can imitate the structure that we perceive as
nature’s grand design and solve our most pressing problems. The science
of "Symbiotics" to coin a new word, or simply taking a jumble of
ordinary material, and turning the ordinary into a great symphony is
our bright hope for the future. A whole new industry may come from this
one endeavor alone.
The likelihood that
scientists such as those at Argonne will make use of the emerging
science of Nanotechnology to solve our energy problems and many other
pressing problems is quite possible.
Our future may be indeed very bright.
