The obvious successes
of past technologies have made politicians and environmentalists
eager to be in the forefront of promoting futuristic schemes for their goals.
Everyone wants to be on the side of the next Great Idea. All too
often these futuristic fantasies are sold to a gullible public, as
well as fellow politicians and the news media, with impressive but
scientifically-flawed arguments that bump up against harsh physical
realities that are immutable. These cannot be changed by any amount
of laws, government spending or propagandizing. Solar power and wind
power are examples. So is global warming.
SOLAR
Sunlight, despite being
plentiful all over the earth, is inherently dilute. It arrives at a
rate of 1 kilowatt per square meter (about 11 square feet) when the
sun shines unobstructed directly overhead. That rate can never be
increased. It imposes an inefficiency that can never be overcome.
As Dr. Petr Beckmann, a professor of electrical engineering, explained:
“No amount of
technology, no amount of money, no genius of human inventiveness can
ever change it....The effort of concentrating it, either by
accumulation in time or by funneling it in space, is so vast that
nothing as puny as man has been able to achieve it; only Nature
herself has the gigantic resources in space, time and energy to do
the job.”
“To get an idea of
how concentrated the energy is in coal, and how dilute sunshine is,
consider a lump of coal needed to make 1 kilowatt-hour of
electricity. It weighs under a pound...its shadow would measure
perhaps 15 square inches. How long would the sun have to shine on
those 15 square inches to bring in 1 kilowatt hour of energy? For
1,000 hours of pure sunshine. In the Arizona desert, where the sun
is out about 12 hours a day, almost three months. For the average
location in the U.S., our little lump of coal would have to be out
for almost half a year to be struck by a total energy of 1 kWh. But
only struck by it; if we wanted to get 1kWh out from that
sunbeam, we would have to divide by the conversion factor....That is
how concentrated the energy is in coal, and how dilute it is in
sunshine.” And the energy in coal is available almost immediately.
WIND
Power from wind energy
also bumps up against immutable physical realities. One is the fact
that the wind doesn't blow all the time. That can never be changed.
Another is that 25 to 60 percent of the time the wind is blowing, it
is at a rate less than the maximum efficiency for the turbine. As a
result, windmills operate at only around 33 to 40 percent of maximum
production level, compared to 90 percent for coal and 95% for nuclear
power. Turbines start producing power with winds at 8 mph, operate
most efficiently at 29-31 mph winds, and must be shut down at 56 mph
winds (though the highest winds have the most energy to be collected)
to avoid potential damage, such as rotor blades flying off or "cause vibration that can shake the turbine into pieces."
Wind turbines are—and
will always be—unable to achieve high efficiency even under the
most favorable conditions. To attain 100 percent efficiency would
mean the blades would stop rotating. The best efficiency achieved is
about 47 percent, which is about as good as it can get because of a
physical law known as the Betz Limit. This has been known for a
hundred years. It was independently discovered by three scientists
in three different countries: Albert Betz (1919) in Germany, Frederck
Lanchester (1915) in Great Britain, and Nicolay Zhukowsky (1920 in
Russia. Their discovery applies to all Newtonian fluids and
identifies the maximum amount of kinetic energy that can be captured
by windmills as 59.3 percent. But the advocates of wind power are
either ignorant of this or willfully ignore it to make wind power
seem feasible for achieving their goals. Wind turbines may be useful in remote locations with
adequate winds where more efficient energy sources are unavailable,
but they will never achieve widespread displacement of more economic
energy without the waste from government subsidies and/or
artificially high electricity rates for consumers.
ETHANOL
The government's
taxpayer support for industry to produce ethanol—for which both
republicans and democrats received huge campaign donations—and the
requirement that consumers buy it at gas pumps are further examples
of forcing us to pay wastefully higher prices for an inferior fuel.
Ethanol has only two-thirds the energy of gasoline, meaning it will
take a car only two-thirds as far as a gallon of gas without ethanol
would take it. And the amount of energy in ethanol cannot be
changed; you cannot get more energy out of ethanol than is in it. No
amount of laws, government spending or research is going to change
that. Ethanol corrodes rubber, aluminum and steel, imposing costs on
the design and construction of surfaces with which it comes in
contact. US
Department of Energy’s Oak Ridge National Laboratory warns against
the use of zinc with ethanol.
(Carburetors are made from alloys of zinc and aluminum.) Because
ethanol attracts water, including moisture from the air, it cannot be
shipped by pipeline—the cheapest method of transport—and must be
distributed by truck.
There have been several
studies of the economics of ethanol. The most thorough was done by
Cornell University Professor David Pimmentel, who also chaired a U.S.
Department of Energy panel to investigate the energetics of ethanol
production. Pimmentel and his associates found that it takes more
energy to produce ethanol than you can get out of it. They found
that “131,000 BTUs are needed to make one gallon of ethanol. One
gallon of ethanol has an energy value of only 77,000 BTU....a net
energy loss of 54,000 BTUs [per gallon].” Pimmentel adds, “That
helps to explain why fossil fuels—not ethanol—are used to produce
ethanol.”
A study by Hosein
Shapouri is championed by pro-ethanol advocates because it disputes
Pimmentel's finding and instead claims a modestly positive net energy
balance. But Howard Hayden, a Professor Emeritus of Physics from the
University of Connecticut and Adjunct Professor at the University of
Southern Colorado, notes that Shapouri et al “use the most
optimistic figures: the best corn yield, the least energy
used for fertilizer, the least energy required for farming,
the most efficient distillation techniques, the most
residual energy (in the form of mash); and in general the most
favorable (but still credible) values for any and all aspects of
[ethanol] production.” Even so, Hayden says that, using Shapouri's
numbers, the net average power available from the ethanol of one acre
of corn would be enough only to keep one 60-watt light bulb burning
continuously for one month. To keep that bulb burning for a year
would require 12 acres of corn, an area larger than nine football fields. (An acre is 43,560 square feet.)
Pimmentel vigorously
defends his study and launches a formidable criticism of Shapouri's
report. He gives this explanation for their differences:
“Pro-ethanol
people make [ethanol] out to be positive by omitting many of the
inputs that go into corn production. For example, they omit the farm
labor — I’m not talking about the farm family, I’m talking
about the farm labor. They omit the farm machinery. They omit the
energy to produce the hybrid corn. They omit the irrigation. I could
go on and on. Anyway, if I did all of those manipulations, I could
achieve also a positive return.
“However,
that’s not the way these assessments are made. You can go check the
noted agricultural economists who have looked at corn as well as
other crops, and they do include the labor, they include the farm
machinery, they include repair of the farm machinery, and so forth
and so on. And so, those are all inputs that the ag economists
include. Why are the pro-ethanol people leaving them out?”
One aspect of the
dispute between Pimmental and Shapouri involves credit for distillers
grains, a byproduct of ethanol fermentation that is used as animal
feed. Pimmental says Shapouri uses an extravagant credit to make
ethanol look good, while Shapouri say Pimmental doesn't account for
the credit. Pimmental's response:
“We
do account for it. Distillers grains, incidentally, are being used as
a substitute for soybean meal. So we went back to the soybean meal,
and examined how it’s produced, and the energy that is required to
produce it. Instead of giving [distillers grains] a 40 to 60 percent
credit as the pro-ethanol people do, we found that the credit should
be more like 9 percent. They [pro-ethanol researchers] are
manipulating the data again.”
How can the correct
numbers for all the inputs be determined? How can each be given an
appropriate weighting in the total picture? How can we be sure that
no inputs are left out? Or manipulated? The free market
automatically does this through the mechanism of prices. It is a
further waste of resources to employ hordes of government regulators
and researchers to determine that which the market can automatically
do more thoroughly and accurately. If the inputs for ethanol, or
anything else, add up to a profitable price for demand of a given
commodity, it will be produced voluntarily in the market. If it is
not profitable, laws and regulations on producers and consumers will
not make it so. They will merely translate the losses (waste) into
higher prices for consumers or taxpayers or to future generations in
the form of depreciating dollars and a growing national debt.
Other biofuels—which
futuristic fantasists acclaim is the next Great Idea in energy—are
worse than corn-based ethanol. They all bump up against the limits
of photosynthesis. Chlorophyll converts sunlight into energy, but
solar energy is dilute to begin with and plants, on average, collect
only one-tenth of one percent of the solar energy available. If
corn-based ethanol were to replace all the oil used in the U.S. for
transportation, 700 million acres of corn would be required, compared
to 408 million acres currently used for all types of crop production.
If soy biodiesel were the substitute, it would require 3.2 billion
acres of soybeans—one billion more acres than the entire U.S.
including Alaska. Nevertheless, in 2013 the Obama administration
announced contracts for $16 million to 3 biofuel plants in Illinois,
Nebraska and California.
ENVIRONMENT
It has long been argued
that solar and wind must be the energy sources of the future,
regardless of cost, because the world will run out of petroleum in a
few centuries. But that argument has been destroyed in recent years
by new drilling techniques, the invention of fracking to extract oil
and gas, and the discovery of hundreds of new oil and gas fields all
over the world—even at extreme depths under the oceans—all of
which mean the world will not exhaust petroleum resources for many
thousands of years, if ever.
The environmentalists
preach that the extractive industries which produce fossil fuels rape
the landscape, pollute the air and water, and consume resources that
should be left in their natural state. They worship the primitive.
Their ideal is a pristine state of nature uncontaminated by
civilization. So they favor renewable energies as being less damaging to the environment. But they ignore the environmental consequence of the
consumption of energy and other resources that solar and wind
utilization requires, which are greater than the traditional energy
industries they deplore.
Like the pro-ethanol
advocates, the advocates of solar and wind energy fail to consider
all the inputs in the claims they are economic. The construction of
a 1,000 MW solar plant requires 35,000 tons of aluminum, 2 million
tons of concrete, 7,500 tons of copper, 600,000 tons of steel, 75,000
tons of glass, and 1,500 tons of chromium and titanium and other
materials. These amounts are about 1,000 times greater than what's
needed to construct a coal-fired or nuclear plant producing the same
power. Nuclear plants require enormous amounts of concrete for the
massive containment structure, but a solar plant of equal capacity
requires 500 times as much..
Those massive material
requirements also consume massive amounts of energy in their
manufacture. These include: 75 million BTU per ton of aluminum, 56
million BTU per ton of steel, 18 million BTU per ton of glass, and 12
million BTU per ton of concrete. And the manufacturing processes
emit pollution of various sorts, some toxic, along with other wastes,
for which disposal sites must be provided at further cost.
Solar and wind
generating plants require vast land areas, with the most favorable
areas being distant from the urban populations that require
electrical power. This means further cost and energy requirements
for establishing a power distribution network.
GLOBAL WARMING
Though it is no longer
believable that the world is going to run out of petroleum, there is
another scare tactic that demands we must use renewable fuels even
if they are uneconomic. That is the threat of global warming ruining
the planet. Isn't saving the world more important than saving money?
But once again, just as in the foregoing examples, inputs have been
left out resulting in a false conclusion.
What has been left out?
Temperature
records were discontinued or no longer included in the data base in
certain cold regions of the world, thus showing an elevated global
temperature record. New measuring stations were added in warm areas,
with the same result. Data was manipulated, falsifying records.
There is no recognition of, or explanation for, the earth being
warmer 1,000 years ago, 3,000 years ago and 10,000 years ago, when
there were no factories or automobiles. Also omitted is that 10,000
years ago when the carbon dioxide level was about the same as today,
the climate rose as much as 6 degrees Celsius in a decade—a hundred
times faster than the rate we are supposed to regard as troubling—yet
without the catastrophic consequences now predicted for global
warming. Also omitted is incontrovertible evidence that rising temperatures
produce rising carbon dioxide levels—not the other way around. Also
omitted are 90,000 measurements of atmospheric carbon dioxide made
between the years 1812 and 1961 and published in 175 technical papers
that give lie to the claim industrialization has increased
atmospheric carbon dioxide. Those measurements were made by top
scientists, including two Nobel Prize winners, using techniques that
are standard textbook procedures; they show an average of 440 ppm
carbon dioxide in 1820 and 1940. Also, ice cores show over 400 ppm
carbon dioxide in 1700 A.D. and 200 A.D., as well as 10,000 years
ago. Samples from Camp Century (Greenland) and Byrd Camp (Antarctica)
range from 250 to nearly 500 ppm over the last 10,000 years. These
make a lie out of the claim in 2013 that the recent atmospheric
carbon dioxide level of 400 ppm is the highest in 3 million years. I
explained these issues in previous postings on this blog so will not
repeat them here. What else has been left out? Almost 5,000
peer-reviewed
scientific papers in professional journals, identified by the
Nongovernmental International Panel on Climate Change, showing the
claim that carbon dioxide causes dangerous global warming is
baseless.
One
doesn't need to be aware of all those shortcomings to realize the
falsity of the global warming propaganda. It was sold to the public
on grounds that the computer models on which it was based represented
the real world. Reality has shown they do not. That is all you need to know. Eighteen years of no
global warming—in the face of enormous increases in carbon dioxide
emission—invalidate the global warming hypothesis. The U.S.
government alone has wasted more than $165 billion since 1993 to
combat global warming from carbon dioxide and caused many billions of
dollars more to be wasted by the private sector.
One
other item missing from the anti-global warming campaign is the role
of the sun. It determines not only the earth's climate but the
carbon dioxide content of its atmosphere!
The
sun's radiation is varied by “sunspot cycles,” disturbances on
the surface of the sun. Magnetic fields rip through the sun's
surface, producing holes in the sun's corona, solar flares, coronal
mass ejections, and changes in the “solar wind,” the stream of
charged particles emanating from the sun. The solar wind, by
modulating the galactic cosmic rays which reach the earth, determines
both the formation of clouds and the
carbon dioxide level in the earth's atmosphere. Sunspot
cycles cause only slight changes in the sun's radiation, but these
changes are amplified many fold by interaction 1) with ozone in the
upper stratosphere, and 2) with clouds in the lower troposphere.
Clouds have a hundred times greater impact on climate and temperature
than CO2.
“Cosmic
radiation comes to the earth from the depths of the universe,
ionizing atoms and molecules in the troposphere, and thus enabling
cloud formation. When the sun's activity is stronger, the solar
magnetic field drives a part of cosmic radiation away from the earth,
fewer clouds are formed in the troposphere, and the earth becomes
warmer,” wrote N.D. Marsh and H. Svensmark, pioneers in this issue.
The process was explained with eloquent simplicity by Theodore
Landsheidt of Canada's Schroeder Institute: “When the solar wind is
strong and cosmic rays are weak, the global cloud cover shrinks. It
expands when cosmic rays are strong because the solar wind is weak.
This effect [is] attributed to cloud seeding by ionized secondary
particles.” Or, as Zbigniew Jaworowski put it more poetically, “The
sun opens and closes a climate-controlling umbrella of clouds over
our heads.”
The
sun also sets the carbon dioxide level in the earth's atmosphere by
the same process. Nigel Calder explains: “The sun sets the level of
carbon dioxide in the earth's atmosphere by the cumulative effect of
variations in the galactic cosmic rays reaching the earth, as
modulated by the solar wind. My results leave no room for CO2
levels due to man-made CO2....nothing
to do with emissions from factories or cars
(emphasis added.)"
After
about 210 years, sunspot cycles “crash” or almost entirely die
out, and the earth can cool dramatically. These unusually cold
periods last several decades. Of greatest concern to us is the
Maunder Minimum, which ran from 1645 to 1715. (See It's the Sun,Stupid for graphs and explanation.) Some years had no sunspots at
all. The astronomer Sporer reported only 50 sunspots during a 30-year
period, compared to 40,000, to 50,000 typical for that length of
time.
In the year 2008 there were no
sunspots at all on 266 days, an ominous indication of extreme cold
weather for several decades despite all the BS about carbon dioxide. While
the believers in anthropological global warming usually try (and fail) to make
their case on a basis of a century or less of data covering the rise
of industrialization, a prominent Russian solar physicist
was looking elsewhere. Looking at 7,500 years of Maunder-type deep
temperature drops, Habibullo Abdussamatov predicted
a slow decline in temperatures would begin as early as 2012-2015 and
lead to a deep freeze in 2050-2060 that will last about fifty years.
In October 2013 he updated his earlier warning: “We are now on an
unavoidable advance towards a deep temperature drop.”
Everyone
knows the sun's heating of the earth and atmosphere is uneven. We
have all witnessed changes in the sun's heat we receive throughout
the day, that it is warmest in midday when the sun is directly
overhead; and as the sun moves across the sky, new volumes of air are
exposed to its heating while others are left behind. This uneven
heating is the basis for wind currents. A similar process takes place
in the oceans, creating ocean currents. According to NASA,
“uneven heating from the sun
drives the
air and ocean
currents that
produce the Earth's climate”
(italics added)
While
others were studying and propagandizing about carbon dioxide, Don
Easterbrook, a geology professor and climate scientist, noticed a
recurring pattern in an ocean cycle known as the Pacific Decadal
Oscillation going back to 1480. Every 25-30 years there was an
alternation of warm and cool ocean cycles. In 2000
he concluded
“the PDO said we're due for a change,” and that happened.
No global warming now for 18 years.
Nitrogen,
oxygen and argon comprise more than 99 percent of our atmosphere.
Water vapor and carbon dioxide are the next most abundant gases.
Carbon Dioxide comprises 0.04 percent and is a weak greenhouse gas; water vapor, a strong one. Joseph D'Aleo, first direct of meteorology,
the Weather Channel, offers this perspective,
“If
the atmosphere was a 100-story building, our annual anthropogenic
(man-made) contribution today would be equivalent to the linoleum on
the first floor.”
Meteorologist Joe Bastardi says only 1/50,000 of the air is man-made and carbon dioxide is “too trivial of a factor” to be of concern regarding global warming, that the whole argument is “tiresome and absurd...Warmists are living in a fantasy world.
Meteorologist Joe Bastardi says only 1/50,000 of the air is man-made and carbon dioxide is “too trivial of a factor” to be of concern regarding global warming, that the whole argument is “tiresome and absurd...Warmists are living in a fantasy world.
“To
those who say there is...a gas (which is only 1/2500th of an
atmosphere in which the most prominent GHG [Greenhouse gas] is water
vapor, and with oceans that have 1,000 times the heat capacity of the
atmosphere) is somehow controlling all this (recall that we once had
an ice age at 7,000 ppm CO2), you live in a fantasy world.
“Then
again, men who have the fantasy of saving the planet by
controlling others are indeed in their own world. It’s up to
those grappling with the real facts to make sure that the world we
live in is one that promotes freedom and the betterment of mankind,
and not one controlled by those who believe they are superior to
everyone else. This is where the real battle is, and not with a trace
gas that has little if anything to do with the climate of a planet
created and designed the way it was.”
We
close with a quote from Reid Bryson, founding chairman of the Department of Meteorology at the
University of Wisconsin: “You can go outside and spit and have the
same effect as a doubling of carbon dioxide.”
Great site. Lots of helpful information here. I am sending it to a few pals ans also sharing in delicious.
