 What has happened to the PV miracle since 1964?
What and where is the Livermore
Lawrence Radiation Lab? If one grew up in Livermore, California, in the sixties, one knows the answer to those questions. Just about everyone in the surrounding subdivisions were scientists working at the
LLRL. 1964 was when solar electrical energy started to become well known in Livermore. There was a Dr. Wells whose son attended Joe Mitchell
junior high school. Dr. Wells was a scientist, but he was a very practical
guy. He had the best looking wife of anybody in town. He built his own
things, including an airplane, a two seater glider, and electronics
stuff. He didn't joke about physics like some of the other scientists,
you know, like, "What would you get if you twisted an electron into the
shape of a pretzel?" That kind of stuff. His son, Sandy, turned out quite
a bit like him.
Anyway one day in 1964, during the year we were in the seventh grade,
Sandy comes up and asks to go in halves on
a science fair project. So we said no we already had a project going. So
he says that it's ok to have two projects and he really needs someone to
split the cost of his project. So you're thinking a) how much is he going
to need? and b) what kind of contraption does he have in mind?
Turns out he wanted twenty dollars. He was going to buy some solar
cell chips from Edmund Scientific Company by mail order. Not the grab bag
imperfects but, the ones with rated wattage. He showed the PV cells in the catalog. Ok,
it sounded interesting. But what do we do with them? His
dad had some books which Sandy had been reading and he thought we would make
a diagram-slash-demonstration exhibit. Oh and one more thing, we'd need
to use slot cars and track. Now you see the real deal. Sandy didn't
have a slot car set and always came over to borrow one. Anyway, we got the
diagrams made and they looked really sharp. And we had three books which
we bookmarked with the best pages. We had a really high powered sunlamp
laying around so we decided to use that for the "photon source." The solar
cells came in the mail while there was still plenty of time, which was
lucky because in those days the mail could take weeks. And without the
solar cells, well you've got no science fair project. So he calls up
and says he's coming over and we can set it up. We clamped the lamp on
a stand and put the track together. It had to be in a circle because a)
we only had one lamp and b) the science fair rules specified the area of
the exhibit.
Sandy was an expert with a solder iron so we had not trouble there.
We got everything set up and switched on the lamp and well, and nothing.
The darn things wouldn't budge. Sandy had thought there would be plenty
of juice for the electric motors to run on. We knew Ohm's Law but at that
time. We had just used the rated
output of the cells for an initial calculation and that had compared favorably enough for us to think
it should have worked. But when the rubber hit the road, nothing moved. We tinkered around. We took the car body off the
chassis to try to lose some weight. Nothing. We took the motors out and
just hooked them up directly to the solar cell lead wires. Nothing. We
soldered the leads in case there was too much resistance from a bad connection.
Nothing.
So was that the end of the project? Nope. We had some dinky little HO
slot cars. They were about one eighth the size of the regular slot cars.
Sandy says hey let's try that. We didn't take the HO cars apart because
we couldn't have reassembled them. To make a short story, Sandy soldered
the leads to the motor and held it up to the lamp and the wheels started
turning around furiously. Oh yeah! It even worked when we set the cars
down on the track and put the lamp a few feet above the circle so that
all areas got the same amount of light.
The smaller HO slot cars zoomed around and around the track. We remember we got a prize of some kind for that. But more importantly, a lot of people whose parents worked at the Lawrence Radiation Laboratory
remembered that exhibit. It was the first time many Livermore Californians had ever heard of
SOLAR CELLS and electricity from sunlight. That science fair was in 1964. A long long
time ago.
What's happened to PV since 1964??? At best it could be characterized as
a waste of time. A more accurate characterization though, would be that
the time hasn't been wasted, it's been used quite effectively, but used
effectively by the wrong parties for the wrong purposes.
What is happenning presently?
Richard Duncan says all it takes at this time is for a critical mass
to "intuit what is happening."
buddycom.com/ecol/Brainfood/duncanoil.html After almost forty years maybe there is a need to clarify the
potential for renewables. Maybe there is a need to separate the hype and
BS from reality. Maybe there is a need to tell others from a small website exactly what's going on whether it's accepted or not. At least
it gives satisfaction that the Rain Forest Guy told you so... IF there is still time.
geocities.com/combusem
Maybe there's a need to say hey folks wake up the propaganda machine
is leading / has led us by the nose to Voltaire's "best of all possible
worlds." A dream come true for both the Papacy and Mr. Undershaft.
There's a chance for a historic opportunity as Bush had repeated again
and again while he was here in Japan. The power elite are so bold, so confident.
All one needs to do is read the news, listen to their spokespersons. All
options are on the table. Except one. And that missing option is a way
out. Is there truth? Yes. And the power elite are the only ones who know
it completely.
We are facing an energy precipice. One which has been obviously well
planned.
We are facing an overpopulation precipice. One which has been obviously
well orchestrated.
There exists a overwhelmingly vast superiority in military technology.
Mass destruction Schmass destruction, indeed.
There is as complete a lack of scientific literacy as there is a will
to question misinformation or motives.
The plutocratic wirepullers know absolutely everything necessary in
complete detail, the rest fritter away time with trivial speculations and
irrelevant repetitive arguments, while the most believe the important condition is
that it must appear that nothing is known for sure amid an ocean of uncertainties.
You'd have to rate that belief, that social construction/distortion of reality, a complete success.
Having fulfilled biblical prophesy any world dominating regime capable
of pulling it off would effectively control the minds, the morality,
and the social construction of reality. FOREVER.
The power elite are in control of the one thing which can not be controlled
by any of us. The signal to begin.
Begin what? The cutoff of the energy flow while the world is still dependant upon fossil fuels. The Yahoo! energyresources group? Jay Hanson had recommended it to answer energy resource questions.
Question 1: How much total electrical energy the USA uses
per annum. Question 2: An energy conversion factor to
convert Quads to other forms of energy, in particular electrical forms.
Why? The energy currently utilized from solar and wind is trivial. Yet some say the potential
is huge, no pun intended. Independent calculations can show one what is
what if King George tries to keep it from being known. Fuel Energy content in British Thermal Units (Btu), Short ton of coal, 21,400,000, Barrel
(42 gallons) of crude oil, 5,800,000, Cubic foot of natural gas, 1,027,
Kilowatt hour of electricity, 3,412 http://en-env.llnl.gov/flow/
http://en-env.llnl.gov/flow/dataused.html
The pdf document which a Randy Udall suggested had the energy flow chart from LLRL. That had
been objective number one, to find the total electrical energy used in
the USA each year from a reliable source. The LLRL is both as
reliable and as politicized as ever because you know what? Even nationalist
zealots need the facts. Objective number two had been to find some conversion
factors to convert the various forms of energy into values which
one could compare apples to apples with. The links in the Udall
doc led to the LLRL site and the energy conversion factors they had used.
Those specific conversion factors were more relevant than some of the ones found elsewhere. Still pending: The total amount of solar energy generated and the total amount
of wind energy generated each year. Thus the course of the growth can be followed from their pathetically miniscule relative amounts to something more promising. By whom? By anyone who can multiply and divide. So BTW,
What do you get if you twist an electron into a pretzel?
A) a really small pretzel.
B) a negatively charged pretzel
C) We give up, what do you get?
D) Nothing, silly you can't twist an electron into a pretzel.

PV, Photovoltaic, a more benign view. Just corporate greed?: This form of energy could be widely used right
now if only the established power companies did not wield so much power in the
halls of congress among the powers that be. Those companies and their allies in
congress have a vested interest in delaying as long as possible, the inevitable
use of solar power. They have invested a lot in the necessary infrastructures
for the extraction, refinement, transportation, and distribution of their
product. They have tapped into the fossil fuels beneath the surface of our
earth and they want to sit on it for as long as they can and let the profits
flow into their bank accounts. They will continue to resist vigorously and with
continued success, the switch over to solar energy precisely because they are
supported by the consumers of their product who collectively demand that they
do so.
The two main flimsy excuses you have heard
for too long are : 1) PV technology is not ready yet. 2) The cost per kW for PV is too high.
These rationalizations have traditionally been
accepted implicitly as a justification for complacency. For several years now,
the efficiency of photovoltaic cells has been between 15% and 20%. That is
sufficient for a level of electrical energy production which would support the
same style of living in the developed nations that people have been accustomed
to expect as normal if the scale were ramped up... So the technology is and has been ready. But, because the
efforts to encourage the necessary increase in scale of production of
photovoltaics have been continually and successfully thwarted, the cost per
kilowatt remains higher than for fossil fuels.
When wide areas of arid land are used to
collect the sun's energy, especially near oceans, seas and other bodies of
water, we will split water molecules into diatomic oxygen and hydrogen
molecules for use as energy. In the absence of solar and wind power, we can not
really use electric engines for automobiles unless we are willing to accept a
net increase in overall output of carbon dioxide, or accept a much wider use of
nuclear energy and at the same time accept lower performance of our vehicles.
Since these three suppositions are false, that leaves us with using solar
panels to split water for the production of hydrogen as the eventual solution
to the problem of what we will use as the energy source for our vehicles and
for other energy needs. We can not eliminate vehicles or the need to produce
vast amounts of electrical energy but, we could stop increasing the number of
vehicles by lowering our population, in both the rich and the poor countries.
The latter is an eventual absolute necessity. There is a finite limit which
will be reached not within the next one hundred years, but within our own
lifetime. In order not to jeapardize their careers or personal futures by being
labeled alarmists, most ecologists and demographers have been unrealistically
generous and intentionally vague in their predictions about our future. Dr.
Paul Ehrlich characterizes as, "preposterous", the blind conviction that the
earth could maintain a population of ten billion. The only question is how soon
the regulation of our numbers will begin and whether the regulation of our
numbers shall be responsible and voluntary or will be by more violent and
tragic means such as war and famine. By now everybody is well aware of this.
Everybody.
The term sustainable is used often.
Neither the hackneyed term sustainable nor the prefix eco- when used in any
particular context renders a concept either sustainable or ecologically sound,
although the power of these linguistic devices is almost universally presumed
to have just such magical proportions.
Everyone has heard of Bernard Shaw, explainer
of reality and spokesperson of the power elite. The power elite are not the
merely super rich, but the true power elite, the families who control the
manufacture of arms and munitions. Although his classic play, Major
Barbara, and the character of Undershaft shall remain forever etched in the
minds of the British royal family with whom Bernard Shaw had had a very close
personal relationship, and in the minds of a handful of professors of English
literature, few are the number of people who remember Undershaft. Fewer
remember Undershaft's reincarnation as Daddy Warbucks. Old folks can remember a
syndicated political newspaper cartoon series called Orphan Annie. That cartoon
series was a means by which the newspaper segment of the media elite
trivialized the role of the power elite in the minds of the working classes.
Daddy Warbucks could be likened to Apophis, destroyed every morning at dawn by
Ra as he delivered the morning newspaper. After several decades of Daddy
Warbucks everyone had become inured to the plutocratic wirepulling which
controlled wars at various locations around the globe. Attention attenuation
pure and simple.
It is in this almost universal state of
ignorance of the role played by Undershaft that the term sustainable is
employed. Ignoring the huge profits to be made from wars, those who are not
members of the power elite feel a strong need to decasualize the spectre of
war. Bruce Springsteen, a famous balladeer for the working class seems
resolutely convinced that war is good for, "absolutely nothin'." A big war
every thirty years or so may be de rigueur for the human race- and for
the power elite. But people like to speak only of past wars. The next war will
never happen. Sustainable is thus a popular term for contemporary inhabitants
of La-La Land. Apple carts never get upset, bad things never happen and this
blissful state of peacefulness can be sustained forever. Undoubtedly this is
what those who speak of sustainable things have in mind.

The world population right now is two to three times what a world without fossil fuels will maitain. Within the next several years grain
production will decrease more rapidly, and fish stocks will become depleted to
such a degree that they will be insufficient for the needs of the world
population. We need to use solar energy to stop destruction of the earth's
ecosystems. We need to use solar energy for this reason and not because it
lowers per capita destructive effect of our population so that we may feel
justified in letting the population increase further.
That's the long and short of it in a
nutshell.

Solar + Fuel Cells =
?
We were thinking about putting solar cells
together with very efficient fuel cells. It seemed like a clever idea. So we
asked the Big Kahuna, Jay Hanson. He must have been in a really rotten mood,
however.
Dear Jay; We thought that once the
solar cells were made, they could be used to create electrical energy forever.
Then they would replace the energy it took to produce them, right? Then
also the solar cells and / or some additional techniques could be used the
electrolyse water to get the hydrogen for fuel cells. What could be more
hunky-dory than that?
The Big Kahuna replied: "No. That's a
popular misconception. The only valid studies that have been done (Odum and his
students) show that solar cells can not support themselves. In other words,
when global oil and North American gas "peak" by the end of this decade, this
civilization comes to a violent, radioactive end. That's why I don't worry
about biodiversity. There won't be any "versity" at all in a radioactive
mushroom cloud." . -- Jay
Why so glum, Jay? Look, here's the multipart
solution. Admittedly it's far fetched. But it is nonetheless possible.
Some in Japan are already thinking in these terms. 1.)
Media tells the truth about energy and overpopulation. 2.)
Population goes down while substantive energy
conservation is instituted. Utterance of obfuscatory remarks, jingoism, and
platitudes are made crimes subject to severe punishment. 3.)
Available dwindling energy sources, including fission, are
used to produce solar and hydrogen energy infrastructure. And that
infrastructure is used as the interim solution for something else which isn't
as yet on the drawing board. 4.) Institutions and social
modes of human behavior are given time to adapt themselves to new
exigencies.
True, solar and hydrogen don't strictly pencil
out ergonometrically. And true, fission fuel won't last forever. But with a
population of four billion humans or hopefully less, this approach is not only
possible, it is very do-able. It beats the heck out of Dr. StrangeLove, doen't
it?
The biggest IF humanity has ever faced. In fact
the biggest IF humanity could ever concieve.
Possible? Possible schmossible. Everything
depends on plutocratic wirepullers. IF they really want Armageddon, they will
make it happen by doing nothing. Make that continuing to do nothing. The
situation has been well understood for quite some time, many decades. The
status quo has humanity on a collision course with Armageddon. All they have to
do is to give instructions to the Media to refrain from initiating the
process by telling the truth. The beautiful thing about the Media is
that it follows its directives very well. The beautiful thing about a democracy
is that it can very easily be made to believe it is, in truth, a democracy.
Which will it be?
Armageddon or Brave New World? When will we know?
When we hear the Media telling the truth, we
will know that the decision has been made to choose a course for a New World.
Until we hear the truth in the Media, the
status quo has humanity on a collision course with Armageddon.
The Media is the message. |

Reviews from Amazon.com:
Jon E Traudt from
Omaha, Nebraska "This book is a great case study in management
and innovation. It shows once again that a small group of dedicated individuals
can compete successfully against much larger competitors. Fuel cells have long
been successful in space craft. Soon you will be able to use them in your
vehicles and buildings. Utility power plants typically discard about 60% of the
heat energy from fuel. A fuel cell in your home would provide electricity
efficiently. Instead of discarding the heat, you could use the fuel cell to
heat your water everyday and provide some winter space heating. A fuel cell in
your vehicle will increase fuel efficiency and eliminate the need for oil
changes. About 40 cubic miles of crude oil remain available for more than six
billion people, and we are consuming more than one cubic mile each year. By
helping to reduce fuel consumption, fuel cells will help us to delay and reduce
the severity of the coming shortages of fossil fuels."
Let the Hydrogen
Revolution Begin! August 10, 2000 Reviewer: A reader from San
Francisco, CA USA "The Hydrogen revolution has started with the unexpected
emergence and success of fuel cell maker Ballard Power Systems. This is a very
exciting industry. We are looking towards a future of abundant clean energy.
Greenland is racing to become the first ever hydrogen economy, extricating
itself from the reliance on foreign oil, and positioning itself as a possible
future exporter of hydrogen. Oil companies are scrambling to redefine
themselves as "energy companies." Innovative companies such as Energy
Conversion Devices have come up with technologies allowing safe hydrogen
storage. I suggest this book for anyone interested in environment and the
future of energy."

Book
Description The use of fuel cells as independent power sources
is expected to become increasingly widespread in the next twenty years. From
electric vehicles to mobile phones, the uses for this environmentally friendly
and efficient energy source are growing. This book seeks to broaden
understanding of the technology by setting out the working methods, behavior,
limitations, special features, and potential of fuel cells in terms accessible
to electrical, automotive, power, and control engineers.
Robert Wilder from
Hawaii "Fuel cells including their ranging balance of plant, are
quite difficult to write about in usefully technical fashion, because the
authors must have expertise across so many various disciplines: i.e. chemistry,
engineering, materials, thermodynamics, systems theory, etc. Yet Larminie and
Dicks are clearly up to the task, and we are the more fortunate for it. They've
done the trick of not only writing a technically-inclined and broadly
encompassing work for a fast-growing field (one that's much in need of such
books now)--but they've also done it in a way that's surprisingly quite
readable. This book could serve as an excellent self-instruction text for those
new to fuel cells, or as a very helpful text for experts in particular fuel
cell types who wish to brush up on other systems. And it could be used in any
university level class. Should I be pursuaded to lend my copy briefly to
someone I know well, then I shall also take care to ensure that I get it back
promptly! It is quite reasonably up to date and highlights for instance Basic
Principles; Efficiencies and Voltages; PEMFCs, AFCs, PAFCs; MCFCs; SOFCs;
various possible fuel types; compressors, turbines, fans, blowers (etc);
delivering FC power, among other topics. Remarkably, this book even happened to
cover a very wide swath of topics that are of a personal interest--despite
their diversity. I might suggest more discussion on just a few quite developing
topics like sodium borohydride as an H2 storage/generation medium. Yet I note
too that near-term emerging topics like that (and much farther off, potential
blue sky topics like carbon nanotubes) are likely best left for a future
edition of this excellent book. In sum, I highly recommend this book. It's
usefully technical yet readable, essential for fuel cell enthusiasts. Though
rather dear, it is I believe well worth the price..."
Understanding Fuel
Cells "This book is an actual text book that can be used for self
learning. It is a year 2000 publication so it has up-to-date information on all
types of fuel cells including an in depth chapter on Proton Exchange Membrane
(PEM) fuel cells that most other books lack. The authors develop concepts and
formulas in such a way that you don't have to have a PhD in electrochemistry to
understand the subject. It also gives specific examples of the concepts and
formulas to show how to use them. This book doesn't just cover the fuel cells
themselves but goes into fuel reforming, pumps, electric motors and DC/AC
inverters. It has many useful diagrams, tables and photos of fuel cells and
their applications. I highly recommend this book to anyone who deals with any
aspect of fuel cells." |

Land, Energy and Water: The Constraints
Governing Ideal U.S. Population Size by David and Marcia Pimentel January
1995
Excerpts:
Prosperity and
Population
"If the United States were to move to a solar
energy-based economy and become self-sustainable, what would be our options and
levels of prosperity? With a self-sustaining solar energy system replacing our
current dependence on fossil energy, the energy availability would be one-fifth
to one-half the current level. Then if the U.S. population remained at its
present level of 246 million, a significant reduction in our current standard
of living would follow. This would occur even if all the energy conservation
measures known today were adopted."
"If, however, the U.S. population wishes to
continue its current high level of energy use and standard of living and
prosperity, then its ideal population should be targeted at 40-100 million
people. With sound energy conservation practices and a drastic reduction of
energy use per capita to less than one-half current usage, it might be possible
to support the current population. One projection suggests a significantly
lower population level and the other a dramatic reduction in the standard of
living. On the positive side, however, we do have sufficient fossil energy,
especially coal, to help us make the needed transition in energy resources and
population numbers over the next century, if we can manage the environmental
impacts."
Conclusion
"At present levels of fertility and migration,
the U.S. population will rise one-third by 2080; A modest increase in fertility
could drive it past a half billion. We could be heading eventually toward
population densities like those in present-day China. Comparisons to China
clearly emphasize why the United States will be unable to maintain its current
level of prosperity and high standard of living, which is based on its
available land, water, energy, and biological resources. We know that supplies
of fossil energy, a nonrenewable resource, are being rapidly depleted. In just
a few years, most U.S. oil resources will be consumed. Fortunately, natural gas
reserves will last for nearly 50 years while coal reserves will carry us beyond
the next century."
"Therefore, we must start now to make the slow
transition from our dependence on fossil fuels to development of solar energy
power as our major energy resource. For the United States to be self-sustaining
in solar energy, given our land, water, and biological resources, our
population should be less than 100 million-significantly less than the current
level of 246 million. However, with a drastic reduction in standard of living,
the current population level might be sustained. With planning and
determination, the United States could gradually reduce its numbers to more
manageable levels."
"The available supply of fossil fuels,
especially coal, will provide the time we need to make the necessary
adjustments involving new solar energy technologies and agricultural practices.
Coupled with this, Americans will have time to change their behavior and
respect for natural resources and the environment."
"With a population of 40 to 100 million, the
United States could become self-sustaining on solar energy while maintaining a
quality environment, provided that sound energy conservation and environmental
policies were in effect to preserve soil, water, air, and biological resources
that sustain life. With these far-reaching changes, we feel confident that
future generations of Americans would be able to enjoy prosperity and have a
high standard of living. Starting to deal with the future before it reaches
crisis level is the only way we will be able to avert real tragedy for our
children's children. By education, fair population control, sound resource
policies, the support of scientific research, and all people working together,
Americans will be able to face the future with optimism and pride."
