January 1974, I began publishing the monthly Living in the
Ozarks Newsletter (LION) using a hand-crank mimeograph machine at my mountain home
in the Arkansas Ozarks. I wrote the newsletter for 36 months to share homesteading
information and thoughts with other back-to-the-landers. In 1976, the Arkansas
History Commission put the 36 newsletters (367 frames) in the state archives.
Unfortunately, the only internet references I found were after 1976 when the LION
name was used by someone else. This story was in the first issue of Living in
the Ozarks Newsletter.<o:p></o:p></div>

As Tzu-Gung was traveling through the regions north of the
river Han, he saw an old man working in his vegetable garden. He had dug an
irrigation ditch. The man would descend into a well, fetch up a vessel of water
in his arms and pour it out into the ditch. While his efforts were tremendous,
the results appeared to be very meager. Tzu-Gung said, “There is a way whereby
you can irrigate a hundred ditches in one day, and whereby you can do much with
little effort. Would you not like to hear of it?” Then the gardener stood up,
looked at him and said, "And what would that be?” Tzu-Gung replied, “You
take a wooden lever, weighted at the back and light in the front. In this way
you can bring up water so quickly that it just gushes out. This is called a
draw-well.” Then anger rose up in the old man’s face and he said, “I have heard
my teacher say that whoever uses machines does all his work like a machine. He
who does his work like a machine grows a heart like a machine, and he who
carries the heart of a machine in his breast loses his simplicity. He who has
lost his simplicity becomes unsure in the strivings of his soul. Uncertainty in
the strivings of the soul is something which does not agree with honest sense.
It is not that I do not know of such things; I am ashamed to use them.”<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
This story has been retold countless times. In his book, “<span style="background: white; mso-bidi-font-family: Arial;">The Physicist's Conception
of Nature,”</span> Werner Heisenberg used the story and wrote “it has often
been said that the far-reaching changes in our environment and in our way of
life wrought by this technical age have also changed dangerously our ways of
thinking” and that “this objection is much older than modern technology and
science, the use of implements going back to man’s earliest beginnings. Thus,
two and a half thousand years ago, the Chinese sage Chuang-Tzu spoke of the
danger of the machine.”<o:p></o:p></div>

Today, people are enamored by movies, television, computers,
the internet, video games and so-called smart phones. People are so mesmerized
by their hand-held devices that they walk into walls. How smart is that?<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<br />
<div class="MsoNormal">
I’m not one to glorify
primitive people. They live short, painful, frightened, and brutish lives.
Instead, I’m inclined to agree with Ishi that modern men and women are “sophisticated
children...smart but not wise” from “Ishi in Two Worlds: A Biography of the Last Wild Indian in North
America” by Theodora Kroeber. Yet
striving to find a balance between appreciation for technology and nature
brings to mind a line from the prologue of Goethe’s Faust: “Es irrt der Mensch
so lang er strebt.” Man will err as long as he strives.<o:p></o:p></div>

I was born in Philadelphia in 1943 and lived there for 19 years watching it fall into economic and social decline after the Second World War boom. Businesses
and white people fled Philly as black people escaping Southern racism migrated North only to find just as hateful Northern racism. Poverty
and crime increased in Philadelphia during the 1950s and I learned how to survive in the Strawberry Mansion section of the city, just one of its many tough neighborhoods.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
I also learned about revolutionaries like George Washington
and Thomas Jefferson. When I rode the subway, I would emerge
from the station into the downtown hustle and bustle and look up in awe at the statue of another revolutionary hero, Benjamin Franklin, atop City Hall. I often visited Franklin’s printing press, Independence
Hall, the Liberty Bell and other historic sites.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
On the way to school, I walked past the Thomas Paine
Institute. Back then, it was just a store-front shop with books and
pamphlets written by American revolutionaries on display in the window.
Each day, a featured book or pamphlet would be opened to a different page for the
passerby to read. Through that window, I read Paine’s “Common Sense”, “The Age
of Reason” and “The Rights of Man” and was introduced to Henry
David Thoreau.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Today, young people read about Thoreau’s quiet life on Walden
Pond, but fewer people read his essay on Civil Disobedience. Even fewer know Thoreau
felt “government is best which governs not at all” and that “The mass of
men serve the state thus, not as men mainly, but as machines with their bodies.
They are the standing army, and the militia, jailors, constables, posse
comitatus.” Few have read that “In most cases there is no free exercise
whatever of the judgment or of the moral sense; but they put themselves on the
level with wood and earth and stones; and wooden men can perhaps be
manufactured that will serve the purpose as well.” Today our wooden men are robots and drones that serve the state.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Thoreau asked if we should obey an unjust law until we can
change it or break the unjust law at once. He wrote that people fear to resist
unjust laws because they fear government reaction and force like we saw in
1970 at Kent State University as government troops gunned down students peacefully protesting an unjust war.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Thoreau ended his essay on civil disobedience with a vision
that is my measure of good government. </div>
<br />
<div class="MsoNormal">
“The authority of government, even such as I am willing to
submit to, - for I will cheerfully obey those who know and can do better than
I, and in many things even those who neither know not can do so well, - is
still an impure one: to be strictly just, it must have the sanction and consent
of the governed. It can have no pure right over my person and property but what
I concede to it. The progress from an absolute to a limited monarchy, from a
limited monarch to a democracy, is a progress toward a true respect for the
individual. Even the Chinese philosopher was wise enough to regard the
individual as the basis of the empire. Is a democracy, such as we know it, the
last improvement possible in government? Is it not possible to take a step
further towards recognizing and organizing the rights of man? There will never
be a really free and enlightened State, until the State comes to recognize the
individual as a higher and independent power from which all its own power and
authority are derived, and treats him accordingly. I please myself with
imagining a State at last which can afford to be just to all men, and to treat
the individual with respect as a neighbor; which even would not think it
inconsistent with its own repose, if a few were to live aloof from it, not
meddling with it, nor embraced by it, who fulfilled all the duties of neighbors
and fellow-men. A State which bore this kind of fruit, and suffered it to drop
off as fast as it ripened, would prepare the way for a still more perfect and
glorious State, which also I have imagined, but not yet anywhere seen.”<o:p></o:p></div>

If you are considering a career in photovoltaics, here are some things to consider:<br />
<br />
1. You have to "do" PV to be "in" PV. A lot of PV workers
don't have PV on their homes or offices. Would you buy a Ford from someone who
drives a Toyota?<br />
2. PV professionals practice their profession (like doctors and other practicing professionals) which
means a commitment to life-long learning about PV.<br />
3. It takes time to develop a good reputation
"rep". Plan on spending at least 2 years eating, sleeping and working
PV full-time before you even begin to earn the reputation as the “PV guy”. You know
you've made it when solar is mentioned in your service area and people
say, "You've got to talk to (your name here). He's the solar expert."<br />
4. You can make more money doing something else. If you are getting into PV
because you think that someday PV will make you rich, forget it.
"Someday" never happens.<br />
5. Do what you love to do and do it well. People reward
competence. In a capitalist society, people reward competence with money. You
won't get rich, but you can earn a good income.<br />
6. Understand the difference between vocation and an avocation.<br />
7. Love, work and knowledge are all there really is to life.<br />
8. Under-promise and over-deliver.<br />
9. Make your customers your friends.<br />
10. Know more electrical engineering and electronics than the next guy, but
also know what you don't know.<br />
11. Laugh a lot. It's good for the digestion.<br />
12. Watch your back. There really are bad people out there.<br />
13. Read everything written by people who actually work with PV.<br />
14. If you can’t memorize the National Electrical Code, then at least know how to
find rules in the code book.<br />
15. Respect your competition. Remember, you look like them to them.<br />
16. Pay your bills on time. Better yet, pre-pay and ask for discounts.<br />
17. Give more than you get.<br />
18. Don't be self-righteous, unless you never ride in combustion vehicles, don't use utility power, grow your own food, and do volunteer work at the
orphanage or hospice. Then you can brag.<br />
19. Visit PV factories, distributors and dealers. See live PV.<br />
20. Take hands-on PV installation classes.<br />
21. Work for a custom homebuilder for a few years to learn contracting and how homes
are built.<br />
22. Work for a commercial electrical contractor for a few years to learn how
the big boys do electrical work.<br />
23. Visit every PV installation and take lots of photos.<o:p></o:p></div>

<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">PV
has evolved from a scientific curiosity to a reliable power source for orbiting
satellites and space stations to cost-effective power for remote homes and
villages and to renewable energy distributed generation in cities and towns
around the world. PV use will continue to rise rapidly as the need to replace
fossil fuel and nuclear power plants becomes increasingly critical. The change
to PV will accelerate as new materials and production methods come on-line. As
more people understand how easy, practical and rewarding it is to use PV, electric
utilities will find ways to integrate privately owned PV into the grid power
mix. PV is already becoming an important addition to utility companies’
portfolios.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">Building
Integrated PV (BIPV) will become commonplace. Today, megawatts of PV roofs,
curtain walls and power generating windows are being built. PV shade structures
and carports are turning parking lots into solar power plants. Tomorrow, BIPV
and PV shade structures, which are simply PV arrays with long legs, will be
deployed on polluted urban wasteland as part of the “brownfields” cleanup
process.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">In
the not-to-distant future - less than 10 years if we focus our resources on
peace and plenty instead of war and waste - buildings will be rated either net
energy consumers or producers. Older, high density, multi-story buildings like
skyscrapers and inner-city hospitals with limited roof space or inadequate
solar access will continue to be net energy consumers while new buildings will be
designed to produce all the energy they consume. Low energy use buildings like
warehouses will have PV roofs that produce excess electricity for sale for
credit or directly to their neighbors.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">Homes
in the future will be super energy efficient and have PV roofs to provide all
the home’s electricity plus power for the homeowner’s electric (EV) or hydrogen
fuel cell automobile. PV modules are already available in many shapes, sizes
and colors to fit any building application. Mounting hardware is already more
user-friendly. Building-integrated mounting and wiring will be inconspicuous.
Multi-purpose inverters that operate with or without batteries will allow you
to choose battery backup now, later, or not at all and back-up power will be
stored as hydrogen and utilized through fuel cells. PV on home, garages and
carports will charge EVs and solar power stored in EV batteries will be fed
back into the utility grid to reduce the need for polluting, inefficient fossil
fuel peaker plants.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">Electric
service panels will be made solar-ready with built-in connections and circuit
breakers for on-site power production. Electricians and tradespeople are
learning how to install PV just as they learned to install heating and air
condition units a few decades ago. Someday all electricians will be as familiar
with PV as they are with lighting equipment.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">PV
will change the way people think about energy production. Most of us are already
concerned about continuously increasing consumption, power plant pollution,
diminishing energy resources and buying oil and gas from nations that harbor
terrorists. On-site PV equipment costs are now included in homeowner’s mortgage
payments in lieu of paying a separate monthly electric bill. Mortgage-financed
PV is already cheaper in many places than utility power. In Asia, Europe and
the United States every year hundreds of thousands of people buy PV for their
homes, schools and businesses for economic and environmental reasons. This
trend is expanding throughout the world.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">In
the future, politicians will be required to provide energy solutions that reduce
the threat of war, improve the environment, and enhance individual freedom. Individuals and corporations will be held
responsible for the energy resources they consume and the health and
environmental impacts of their actions. PV will help everyone to meet these
goals.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">On-site
PV use will grow by thousands of megawatts every year. Large-scale centralized
PV power plants will still be required to power urban areas that house over 50%
of world population, but plans are on the drawing board for a global network of
PV arrays that will feed into a global electric grid. The Genesis Project is
one such plan. Genesis, which stands for Global Energy Network Equipped with
Solar cells and International Superconductor grids, is the brainchild of Dr.
Yukinori Kuwano, one PV’s most innovative scientists and founder of Sanyo’s PV
division. His 200-year plan is to make PV the planet’s prime energy source. (1)<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">The
Genesis Project is not science fiction. A look at Earth from space shows that
rainy and cloudy areas cover less than 30% of the total land mass and that it
is always daylight on one side of the globe. A global PV power grid connected
by super-conducting cables would enable daylight areas to provide clean solar
energy around-the-clock. Super-conducting cables are practical today and plans
are to increase their use. (2)<o:p></o:p></span></div>

<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">When
Dr. Kuwano first proposed the Genesis Project, global energy demands were the
equivalent of 14 billion barrels of crude oil per year. About 4% of the world's
desert area (800 km square) covered with 10% efficient solar cells could meet
this requirement.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">Is
a global PV grid possible? People who install PV power generation systems on
their grid-connected homes and businesses are building the global PV network
right now. As this trend grows, national networks will then be connected by
superconductor cables now in development.<o:p></o:p></span></div>
<div class="MsoNormal" style="line-height: 150%;">
<br /></div>
<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">The
United States, Canada and parts of Mexico are already interconnected as are the
electric power grids of some European countries. The "Silk Road Genesis,”
proposed by the Tokyu Construction Company, calls for the construction of PV
power plants along that ancient trade route. The first stage of the project,
which now includes the support of Sanyo and other companies, involves building over
a hundred 100-megawatt PV plants along the Silk Road by 2030. <o:p></o:p></span></div>

<div class="MsoNormal" style="line-height: 150%;">
<span style="font-family: "Times New Roman","serif";">Desertec
is another large scale project aimed at creating a global renewable energy plan
based on the concept of harnessing sustainable power from sites where renewable
sources of energy are more abundant and transferring it through high-voltage
direct current transmission to consumption centers in north Africa and Europe.
All kinds of renewable energy sources are envisioned, but the sun-rich deserts
of the world play a special role. (3)<o:p></o:p></span></div>

if it takes 50 years for a global electric grid to materialize, hundreds of

August 1999, I asked some hands-on PV pioneers who had the
first photovoltaic powered personal computer (PV powered PC). Here are their
responses and some comments.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
My own PV powered PC experience began July 1982. While living in the Arkansas Ozark mountains, I got an Apple II Plus. I wanted to connect the computer directly to home 12-volt DC PV system instead of using an inverter so I
called Apple Tech Support to make sure what I wanted to do would not harm the computer. Apple technicians told me that my computer
was the first PC they knew of that was PV powered. I connected my 12-volt PV
system battery bank (6 each 2-volt 400 amp-hour C&D lead-acid cells) to a separate 12-volt
group of gel cells. The gel cell 12-volt output was connected directly to the Apple’s
hard drive and the computer's 5-volt RAM was connected through a voltage-dropping resistor.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
When I moved to Los Angeles in 1982, I continued to power my Apple II with PV using a Tripplite 550 inverter with a 120-volt square wave output. I have also
owned Compaq, Kaypro, IBM and PC clones that I powered with Tripplite, Heart
and Trace inverters. Most PC power supplies can work with unfiltered utility power
so they could also work with most of the square and stepped square wave inverters
available back then. I also powered my Sharp laptop and Epson notebook with PV power and a
voltage dropping resistor into the internal battery. Computers and PV power are
very compatible. This blog was written on a desktop PC in a completely solar
powered home and office. See <a href="http://www.solarsolar.com/oursys.html">http://www.solarsolar.com/oursys.html</a><o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Here are a few of the 1999 RE-Wrenches replies. Someone wrote that a
company named “KISS” (Keep It Simple Solar) has a patent for a solar powered
computer, but I couldn’t confirm it. He also wrote that KISS sold out to Advance Power (Power
Experts) around 1997 or 1998. In 199, Sunwize offered a PV module to power PCs. IBM
had an interesting patent for an amorphous PV module that was behind the PC’s
LCD screen. Office or outdoor light that passed through the computer screen's non-energized
pixels and onto the PV module could charge an internal battery or capacitor. That was more than 15 years ago yet there are still no computers or hand-held screen devices that do not require
plug-in charging.<o:p></o:p></div>

Phil Karn <a href="http://www.ka9q.net/pv/">http://www.ka9q.net/pv/</a> reported: I dunno who was
first, but right now (1999) I have three Linux systems running on solar power
all day, crunching Seti@Home datasets. There should be a separate competitive
category for solar-powered SETI. The last time I measured power consumption with
a Brand Electronics power meter my three computers plus networking gear
(various Enet hubs, cable modem, ADSL box, GPS receiver, etc.) was about 330
watts. That's with Seti@Home running on all four CPUs (one machine is
dual-CPU). Idle CPUs draw significantly less power, at least under Linux. I
figure my home computers use about twice as much energy as my EV1 (see Note) does
on a normal daily commute (about 10 miles round trip). SDG&E comes to swap
my meter tomorrow. Then I'm clear to enter SELL mode. I have an interesting
saga to tell about doing net metering with TOU tariffing; perhaps I should
write that up too. The bottom line is that little old me was able to get a big
bad utility to change a tariff just for me. Of course, it helped to have
California state law on my side. My note: The EV1 was General Motors’ wonderful electric
vehicle that they recalled and destroyed. See <a href="http://www.whokilledtheelectriccar.com/">http://www.whokilledtheelectriccar.com/</a><o:p></o:p></div>

Walt Pyle <a href="http://hionsolar.com/">http://hionsolar.com/</a> reported: I doubt that we
were the first, but we powered our Imsai 8080 that was built as a kit from a
bag of parts in 1976 with 10 each 10-watt Solarex silicone-potted
single-crystal silicon modules. Those PVs charged a pair of 8-volt locomotive
batteries with 12 volts tapped off and one cell not used. I used a Tripplite square
wave inverter to go from 12vdc to 120vac that rattled the transformer windings
of the Imsai. Later, we replaced the Tripplite with a Trace inverter.<o:p></o:p></div>

Loren Amelang reported: I built a Z-80 S-100 system in 1981
which took DC power from the PV array that powered my home and well near Philo,
CA. At that time there were 6 each 35W Solec panels in a 12V array. A multipole
switch moved several lead acid batteries between 12V charging configuration,
and the complex series array needed to get the 8 and +-16 Volt S-100 supplies.
It had the PerSci servo-actuated 8" DSDD dual floppy drive for the fastest
response short of a real 14" hard drive (which I didn't feel I had enough
PV to run). It had a 12", 12 VDC monochrome serial ASCII terminal, and/or
a directly connected (5 inch?) monitor from an Osborne. The original Epson
9-pin printer (made entirely from metal!) ran from a Heathkit inverter when
needed. It even had a 12VDC 300 baud modem, but there was no phone line. To access
Micro-Net I would plug the ASCII terminal and the (acoustic coupled) modem into
my pickup and drive to the only pay phone in the next town. When the Tandy
Model 100 (the original laptop) came out, it made this payphone surfing much
simpler, and became the serial terminal for the S-100 box. That same Tandy 100
is still plugged into my PV system right now, logging data from my water
system! Today I have various modern laptops, plus a P200 ISA backplane system running
from an Aquire, Inc. ACE-870C 24VDC input switching power supply with all the
normal regulated PC voltage outputs. And the original flat panel Apple Studio
Display, 25 watts for the most beautiful 15" screen image I've seen
anywhere, plus it takes S-Video in from the satellite system. See a video about
Loren’s off-grid home at <a href="http://www.youtube.com/watch?v=m5rM7QDi_5E">http://www.youtube.com/watch?v=m5rM7QDi_5E</a><o:p></o:p></div>

These replies plus email and snailmail exchanges with
thousands of PV users confirmed what I had imagined. Back before the turn of the
century, there were thousands of PV powered PCs ranging from the computers used by Home
Power magazine founders and many of their readers, to Peace Corp volunteers and
missionaries in developing countries, to techies and amateur radio operators,
to people who just happen to have their PC plugged into their PV powered home.<o:p></o:p></div>

In the 1970s, I was living off-grid in the Boston Mountains of the
Arkansas Ozarks. I did some PV module group purchases in 1979, but the first PV
Bulk Buy was August 1980 when I bought 58 Arco Solar 33-watt modules from Steve
Baer at Zomeworks. 4 modules were added to my PV system and rest were for a few other people
in northwest Arkansas.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
In 1981, I presented a paper about my PV powered home at the International Solar Energy Society (ISES) Conference in
Philadelphia. At that conference, I met Paul Maycock, Karl Boer, Stephen Strong,
and several other PV pioneers. I also met Rodale Press editor, Michael LaFavore. In the
Summer of 1981, Michael visited my home and wrote an article about it in the
November 1981 issue of Organic Gardening magazine. See
<a href="http://www.solarsolar.com/solarog.html">http://www.solarsolar.com/solarog.html</a><o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Michael’s article encouraged more than 900 people to write to me asking how they could start using PV. Hundreds more people wrote to me after
reading about my PV system and the PV Bulk Buy in Solar Age magazine,
Christian Science Monitor, Progressive Architecture, Mother Earth News, and
other publications. By the end of 1981, I was organizing regular PV Bulk Buys and shipping more
than 100 of the “new high-power" Arco Solar 35-watt modules at $375 per module including UPS charges. By today’s standards, this would be a small order of very expensive solar modules, but in 1981 less than $11/watt was the lowest price for
do-it-yourselfers.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
My supplier, Steve Baer, told me to buy directly from his distributor and
introduced me to William Lamb. Bill Lamb was friends Bill Yerkes who founded Solar Technology International in 1975. Atlantic Richfield bought Yerkes PV company in 1978 and renamed it Arco Solar making Wm. Lamb Company the world’s first PV wholesale
distributor.</div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
By January 1982, my PV Bulk Buy mailing list had grown to almost 3,000 people
and I had switched from mailing almost monthly letters to everyone to publishing The PV Network News on newsprint to announce regular Bulk
Buys and share info with do-it-yourselfers.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
The PV Network continued to grow as word spread about the PV Bulk Buys. March 1982, Bill Lamb invited me to California to tour Arco
Solar’s factory located in Chatsworth at that time. Bill and the Arco Solar
people were big supporters of the PV Bulk Buy and gave me an Apple II
computer to facilitate publishing the PV Network News. I couldn’t resist
opening the computer chassis and connecting my home’s 12-volt DC PV system directly to
the computer’s DC circuitry. In those days, PV pioneers were opening radios,
tvs, record turntables, tools and other 120-volt AC equipment to bypass input
transformers and connect equipment directly to their PV systems.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
By the Fall of 1982, I was regularly shipping more than 1,600 Arco
Solar modules to do-it-yourselfers all over the United States but mostly in California. I
wanted to offer another brand solar module so I contacted John K., who was working
for Photowatt, a French company with a PV module assembly factory in Arizona.
John liked the bulk-buy idea as did David K., a PV equipment distributor, so we
did a Photowatt module Bulk Buy shipped from David’s shop in northern
California. Later, I also offered Kyocera modules.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
My Ozark home was off-grid with no phone and the only way to communicate with me was by mail. I didn't to deal with personal checks so people had to pay for their PV modules with cashier’s
checks or postal money orders sent to my Pettigrew, Arkansas General Delivery
address. This was old-style mail-order. (Remember the ads in magazines and back of comic
books?) People were very trusting. I don’t think this
could happen nowadays because rip-off artists have just about killed people’s
trust.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
I lived several miles from the paved roads or as locals would say “so far back in the woods that I used hoot-owls for roosters.” Once
a week, I would drive my truck or ride my horse to the post office in
Pettigrew to get my mail and the PV Bulk Buy orders. Back then, Pettigrew was just a 12x12 feet post office where the spit-and-whittle old-timers met, a general
store, a few houses, a repair shop with a trailer home out back, and a junkyard
full of rusting cars and trucks. Pettigrew is still just a little settlement on
Route 16 near the mouth of the White River in the beautiful Arkansas Ozarks.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Once a week, I would drive to the bank in Huntsville,
Arkansas to convert Bulk Buy checks and money orders into one big cashier’s check
and then mail it along with people's shipping addresses to Bill Lamb in North Hollywood (not "Hollywood") California. Bill would ship the modules promptly and everyone was happy. Back then Huntsville, the
Madison County seat, had about 1,200 inhabitants and the county was the
2nd poorest in the 2nd poorest state (they use to say "thank god for
Mississippi"). Today, Huntsville has about 2,400 people and Arkansas
is the 3rd poorest state. Madison County remains poor.<o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
Interestingly, those early PV Bulk Buy modules are still
producing solar electricity. See
<a href="http://www.greenbuildingadvisor.com/blogs/dept/musings/testing-thirty-year-old-photovoltaic-module">http://www.greenbuildingadvisor.com/blogs/dept/musings/testing-thirty-year-old-photovoltaic-module</a><o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
In November 1982, after living in the Ozarks for 10 years, I decided
to give up subsistence living and do what I could to make society better. Bill Lamb encouraged me to return to Los Angeles where had lived 1966 when I got out of the Army until 1970 when I moved to Oakland, California. LA in the 1960s was fantastic. I had a wonderful time. I liked the weather, the beaches
and the people so I returned to LA LA Land and worked as Bill’s sales manager until he died
in 1987. During that time, the PV industry grew rapidly thanks to Jimmy
Carter’s pro-solar policies. Ronald Reagan’s anti-solar policies
killed the federal tax credit for solar December 1985, but PV had taken root and nothing could
stop its growth. <o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<div class="MsoNormal">
George Orwell's 1984 did not happen as predicted. In fact, 1984 was a great year for
me. I was so busy selling PV that I asked Paul Wilkins, a New Mexico
PV pioneer, to take over the PV Network News. Paul continued sharing PV
information until he died in 2010. Also in 1984, Fran and I got married and we bought
our home. That same year, the defunct National Energy Journal awarded me Solar Man of
the Year and Greg Johanson and I built the solar vehicle that established the
Guinness World Record category and started the international pastime of solar
car racing. See <a href="http://www.solarsolar.com/suncar.html" target="_blank">http://www.solarsolar.com/suncar.html </a><o:p></o:p></div>
<div class="MsoNormal">
<br /></div>
<br />
<div class="MsoNormal">
I was fortunate to have caught the PV wave of the
future at the right time and have worked on a lot of interesting PV projects with
some wonderful people. I no longer sell PV equipment, but I still like to work
on interesting solar projects so email if you need a PV expert.<o:p></o:p></div>
