Many moons ago, (as I recounted in my
book ‘Rocket Surgeon’,
and also in a recent Speculative Fiction Showcase article), I wanted to be
Jacques Cousteau.
The inventor of the aqualung, several
submersibles and captain of ‘Calypso’ caught my imagination and sense of wonder
in several specials he did for the National Geographic Society.
As I matured, I knew what I wanted to do
when I grew up. In fact, after studying the sciences and math in high school, I
went so far as to enroll in college to major in Ocean Engineering.
Today, I am struck with my naïve
optimism to both try to emulate the eminent National Geographic Awarded
scientist and explorer, and the unmitigated balls it takes to call ANYONE an
‘Ocean Engineer.’
As I have monotonously pointed out in
all of my writings regarding Global Climate Change, it is very apparent that
the sheer orders of magnitude of trying to stop waves, infiltrate the
atmosphere with climate shredding chemicals to try to reduce the destructive
force of hurricanes, or even mold the coastline into some semblance of
manageable terrain is the very epitome of hubris.
Now, the more well-travelled among us
will no doubt point to Holland, or China’s vast engineering efforts as evidence
that we can throttle natural forces.
Scientists and engineers can point to
the Trieste or nuclear-powered
aircraft carriers as more evidence that we can indeed create resilient
structures that can withstand much of what our planet can send against us.
But, after all of that, we don’t have
the real proof of mastery of the oceans: undersea cities.
Why?
CORROSION,
STRESS, MATERIALS SCIENCE and YOU
One of the most interesting scientific
experiments I performed in my career in aerospace was developing coatings for
the TF-30 jet turbine engine that powered the Grumman F-14 Tomcat.[1]
FIGURE
1: A.E.’S FAVORITE JET FIGHTER OF ALL TIME![2]
The engine was problematic, as it was the
world's first production afterburning turbofan.
This complicated mouthful of
techno-speak meant that it had to overcome not only the incipient issues of the
turbofan system, but it also needed to address specific flight regime
parameters needed for supersonic operation via afterburning.
FIGURE
2: A.E.’S NOT-SO-FAVORITE ENGINE OF ALL TIME![3]
So, there was intense focus placed on
assuring that the engine would function from both land-based and carrier-based groups.[4]
One problem we faced was titanium fires,
which can occur when something hits the engine at speed and knocks pieces off
and into the working bits.
When an engine is operating, it is
rotating at very high rates, and the ingestion of small amounts of debris can
be very impressively destructive. Jet engines are tested for this Foreign
Object Damage (FOD) in several ways.
One interesting method is performed by
shooting frozen turkeys or chickens into the front of the running engine the
while they are mounted on a test rig. The results are spectacularly grotesque,
as the bird carcasses are shredded - and presumably, roasted – and then ejected
from the ass-end of the engine.[5]
The engineering that goes into assuring
that bird strikes are survivable is important and rigorous.
Some of the tests that are developed, such as
salt-spray exposure, are routine and self-evident regarding an aircraft that
spends much of its time on the runway deck of a carrier.
Others, such as simply rotating the
parts of the engine holding the blades rapidly until they completely shatter,
are not as obvious in their intention.
All of these tests add up to data that
allows the scientists and engineers to predict failure modes, which is to say,
what will cause them to break.
------
The issue at hand was that the vanes and
blades in the TF-30 were corroding, due to exposure to the winds and spray from
the ocean waves. The water would collect on the inlet and then, during startup,
would get sucked into the engine. When the engine was then operating at
temperature, this caused an environment that was very hostile to the
superalloys that comprised the working parts.
We were tasked to study ways to prevent
or mitigate this, so we sought out vendors who could lay claim that they had
various materials that could aid in protecting the substrate metals.
Some of these solutions were just paint,
in which the parts would be dipped. Some were sprayed onto the individual
components, and then it would all be assembled. Some were applied with exotic
techniques such as ion-vapor deposition.
All of them were advertised as being
very good products to prevent corrosion from salt water exposure.
And, the reason for that was that all of them were in current use on oil
platforms, naval and commercial vessels, seawalls and other structures that
interacted with water. They had been exposed and tested to the real-world for
decades, and almost a century, in one particular case.
The science was well-established, with
the chemical effects of galvanization and corrosion amongst the most intensely
studied areas in every field in which it could apply.
From the nails holding on the shoes of
horses, to the glues and rivets that held together satellites, corrosion was
Man’s ancient nemesis.
We tested these elite coatings, trying
to gauge which one could best solve our problem.
The punch line was that all of them
failed the salt-water test, to one degree or another – eventually.
The best candidates outlasted their
competitors by very large margins. Paints or physically applied products would
chip, exposing the base material to the elements. That they failed predictably and repeatably
was good, solid Scientific Method kind of behavior! It confirmed our
suspicions, as we tested hypothesis after hypothesis, adding to our knowledge
base.
But even the best anticorrosive products
eventually succumbed to the simplest of corrosion: rusting.
When immersed for a long enough time, everything
that could rust, would rust.
This mechanism also facilitated galvanic
corrosion, which is when the ions in the water combine to form nasty things
that pit the metal.
To combat this, we used deionized[6] distilled water. It was non-ionic,
having been specially filtered to remove almost 100% of the one thing that
propagated this reaction.
The point being that, even structures
that are exposed to the ocean for long periods of time will eventually corrode,
or weaken, and failures are inevitable.
Oil rigs, submarines, freighters,
warships and all other constructions (i.e. dams, seawalls, piers, jetties,
docks, drydocks and even houseboats) fight the losing battle with entropy every
second of every day.
When you are Holland, keeping the sea at
bay is an unending fight against waves, tides, and storms.
When you are China, the immense dams,
bridges and seawalls are constantly being chipped away by time and tide.
Being above the water is of huge benefit
in performing these exercises. It makes all the details surrounding breathable
air, water pressure, shear strength, compressive stresses, statics and dynamic
forces and, above all, having enough time to react manageable.
But, if you are living in Atlantis, this is a matter of life and
death.

I love James Bond movies, as you know,
and The Spy Who Loved Me is probably
in my top three for the series.
The villain, Carl Stromberg, lives in an
underwater castle.
It has a sealed helicopter pad
(waterproof!) where he lets Caroline Munro store her Bell chopper, in between
chasing Bond and shooting machine guns at Agent Triple X (the always lovely
Barbara Bach!)
Dining on a sea bass[7]
while ordering his henchman Jaws to make sure Bond is stopped, Stromberg clicks
a button, and his castle, Atlantis,
rises like an evil black skull-spider from the depths, to the classical
melodies of Mozart.
FIGURE
3: A.E.’S FAVORITE DWELLING OF ALL TIME![8]
Now, the sheer arrogance of Stromberg’s
will to halt the effects of Nature on his abode still staggers me to this day!
Let’s dissect just a few things about
this fantastic structure:
- It is based on an oil-drilling platform and located off the coast of Sardinia
- It is coated with some manner of sonar and radar transparent or absorbent material
- It is large enough to house an aircraft hangar and satellite transmission station
- Is possibly nuclear powered
- Can raise and lower from the ocean floor, deep enough that Bond needs a minisub to get to it*
- Houses command and control for running missile tracking systems
- Is apparently immune to maritime or statutory law
Clearly, Stromberg has invested billions
of dollars into constructing and maintaining this thing. As well, one can
imagine that he is constantly having to ‘fix’ things. Like, leaks…
FIGURE
4: A.E.’S FAVORITE AUTOMOBILE OF ALL TIME?[9]
Stromberg can watch the water flowing down
the windows of Atlantis, as it rises
from the sea, and feed his secretary to his pet sharks, all while sipping some
Bordeaux. A wonderful example of free-market capitalism at its best.
Oh, and, lest we forget, he’s batshit
crazy, too.
His plan is to blow up the world by
causing World War III when Russian and United Kingdom nuclear subs shoot
missiles at London and Moscow. It’s a dog’s breakfast of Cold War era intrigue,
but luckily Bond shoots Stromberg in the balls[10],
and saves the day.
Score one for the good guys!

The problem of how Atlantis operated vexed me for many years,
During one showing, I was blessed enough
to be in the company of one of the designers of the submersible Lotus Esprit.[11]
We talked some shop, and I was
disappointed to learn the truth about the Hollywood magic on the screen: the
cars were either miniatures, modified fiberglass shells, or sets. Who knew?
He did go on about the difficulties that
the film crews had surrounding the electrical circuits, lighting and –
corrosion.
I sighed, and mentioned the TF-30
issues, carefully avoiding the classified aspects of the research.
In the end, I came away with a new
appreciation for how difficult building any manner of structure to survive
exposure to the oceans must be.
My dreams of undersea cities were
relegated to the science fiction of Frank Herbert,[12] Frederik
Pohl and Jack Williamson ‘Undersea City’
trilogy, and, of course, Gerry Anderson’s ‘Stingray’.

One of the harshest lessons of my young,
naïve life, and one that ranks right up there with discovering that Ocean
Engineers usually end up as Assistant Managers at Walmart.[14]
COMING SOON:
The writing of my satirical trilogy[15]
has taken priority, so I have moved some of the promised articles to the back
burner, for the nonce.
However, I have begun writing a three-part
series for Speculative Fiction Showcase that addresses the eagerly awaited Sci-Fi Weapons focus.
Don’t worry, Bovine Flatulence is not far behind![16]
There is so much material on the weapons
research, th
at I am also writing a Guide for Authors on this!

[6] On a chemical
level, atoms are made of protons, neutrons and electrons. Whenever an electron
is added to or removed from the atom, it becomes charged, and is known as an
ion. Ions want to return to being well-balanced atoms, so they react with other
atoms nearby to cancel out that imbalance. This is one mechanism for corrosion.

[10] I am NOT kidding!
[11] Perry Oceanographic was located up the road
from me, and down the road from the aerospace company where I was employed.
[12] Yes, the guy who wrote ‘Dune’… look up ‘Under Pressure’
[13] God, I really enjoyed all of the stuff that Gerry Anderson made! It
was so cool, and for its time, really stretched the imagination of
impressionable young boys! And girls! Lady Penelope and Tin-Tin Kyrano were
role models that went far afield of the Barbie doll sensibilities of that
simpler age. Did you know that The Tracy brothers were named after Mercury
Seven astronauts: Scott Carpenter, John Glenn, Virgil "Gus" Grissom,
Gordon Cooper and Alan Shepard! What a time to be a kid!
[14] So, this is a rather long story. When I entered college way back in
the day, I took the curricula that would lead to a Bachelor’s of Science degree
in Ocean Engineering, from a prestigious school in South Florida. I have
documented my academic travails elsewhere…
During that time, I became employed
in aerospace. Needing money, as young people often do, I took a second job as a
stock boy at a store that was the ancestor of Walmart. It’s long gone…
One day, I was stocking shelves and
occasioned to engage in a bit of banter with the Assistant Manager. Let’s call
him ‘Bob.’
Bob asked where I attended classes,
and what my major was. I informed him. He informed me he’d attained that exact
degree, some years earlier. I put down the box of cheap drinking glasses I was
moving to a higher shelf, perplexed. Surely, there was some mistake of
interpretation.
“An O.E.? From Prestigious U?” I
gasped.
“Yes,” he replied.
“Why on earth do you work here,
then?” I asked, incredulous.
“Better pay, and you don’t have to go
to Antarctica or work for the Navy,” he said, deadpan.
I resolved to look into this new
information, and soon thereafter, had transferred into Mechanical Engineering.
How I ended up with three unrelated
degrees is a tale best left for another time.
[15] ‘Imperius Wrecks,’ ‘Second
Coming,’ and the soon-to-be-released ‘Third Trimester’!
