“Mr. Trump, tear down that Wall”
Written by Dan McDonald
Presidential candidate Donald Trump
wants to build a wall to help keep out immigrants entering the United States.
There are other things he could build that might do a better job of minimizing
immigration entering the United States from Mexico. The reality is that illegal
immigration is fueled by a large gap in opportunity depending on which side of
the American-Mexican border one lives on.
We need to imagine different ways of
addressing the illegal immigration issue. Imagine that you are living in
Mexico. You don’t speak English fluently, but you know there are Spanish
speaking people living in many areas of the United States who can help you
learn the language. You live in a nation with mediocre infrastructure, high
unemployment, and large numbers of people working for less than $5 a day. You
learn that across the border there are cities where the minimum wage is $15 an
hour. You are faced with a dilemma. You can try to enter the USA legally and
probably will never be able to do so. You can enter illegally and maybe you
will get caught and returned to Mexico, but you know many have made the illegal
entry and have been able to stay and their children born in the USA have an
opportunity for a stable life. Which is more important to your system of
values? Is it more important that you obey American laws that seem to protect a
huge wage gap between the USA and Mexico or do you try to provide a better
opportunity for your children whatever might happen to you?
Presently the goal of Presidential
candidate Donald Trump is to try to build a wall to keep people from entering
the United States illegally. That can be done but it will involve a huge cost
of building the structure and a continual cost of providing enough people to
guard the wall and keep it maintained. It will do nothing to address the
reasons why people are willing to cross a border where they do not fluently
speak the main language, where they will often be treated with disrespect, and
yet they feel that they are giving their children an opportunity to live stable
lives with their spouse and children. There will still be people who find a way
to work around any wall to keep out immigrants who are entering illegally.
But the other possibility we need to
consider is if it might not be actually cheaper to build pieces of infrastructure
in strategic areas within Mexico that might help to create within Mexico the
hope that life will get better even if one remains in Mexico.
To this end I wonder if instead of
spending the money for building a wall between our nations, we built something
like solar wind tunnels in the desert regions of both the United States and
Mexico. There are actually two kinds of solar wind tower models to choose from.
In past years solar wind tunnels were built using an updraft method. At the
bottom of the tower, large tube structures have air forced into them which is
then heated by the Sun heating the tubes. As the air heats from a number of
tubes, then the hot air rises into a tower and is pushed by the heated air
looking to expand and as the air flows upwards turbines placed throughout the
tower are turned producing electricity. There is virtually no pollution in the
process and the desert that covers much of Mexico as well as areas of our
American West would be an ideal place to build these structures.
A second kind of solar wind tunnel
is now being developed with the hopes of building the first of its kind in the
city of San Luis, a city along the border of Arizona and Mexico. You can read
about this innovative solar wind tunnel that uses a downdraft instead of an
updraft here.
Instead of using tubes at the bottom to collect, heat, and force air upwards
into the tower; the method used in this second solar wind tower pumps water
across the top of the tower cooling the air around the top of the tower. The
result is the cooled air naturally descends into the tower and then multiple
turbines at the bottom of the tower produces electricity. The advantage of this
method is that electricity can be produced at night as well as in the day using
the cooling of air to drive the generators. The disadvantage is that it will
require water but much of the water will be able to be recollected in the
process and will for the most part not be polluted. The tower planned for
building at San Luis will cost approximately $1.5 billion. The tower planned at
San Luis is expected to produce an amount of electricity equivalent to that
produced by the Hoover Dam. The cost of the electricity produced to consumer is
projected to be about the same as the cost of natural gas produced electricity
in present power plants. This is minimal pollution, tremendous amounts of
energy produced at quite competitive costs.
I wonder how much Mr. Trump’s wall
will cost to build, man, and maintain. Will it produce electricity? Will it do
anything to give the average Mexican laborer a reason to hope? We could build
towers as part of a beginning to build a modern electricity producing grid
capable of powering a 21st century economy. The American electrical
grid is in need of modernization. The Mexican electrical grid has been less
than sufficient for its twentieth Century needs. Mr. Trump wants to get Mexico
to pay for the wall he dreams of building, you know it will be a really great
wall but how do we really think Mexico will pay for the wall. But these solar
wind powers that will help create the power to make Mexican lives better, help energize
increased productivity and help raise standards of living might be something
that Mexico would be interested in contributing to the towers’ building.
It is at least something worth
considering. Maybe Mr. Trump or another person elected to the presidency can
tear down the wall before it is even built.
