Solar Power advances
The world is facing huge energy problems. As we pointed out in the last
eNews, world production of oil will likely peak and subsequently decline,
and this will force petroleum companies to raise prices and look for oil
from unconventional sources. At the same time, the environmental and
health problems caused by fossil fuels are also rousing critics and
adding to cleanup and insurance costs.
More than 3,000 megawatts of solar-powered electricity is generated in
the world today. World production of photo-voltaic cells grew 32% from
2002 to 2003, with more growth expected this year. It took 30 years
(1969-99) to produce the first gigawatt (billion watts) of solar-power.
Total production has tripled since then.
In 2003, the solar power industry generated $5.2 billion in revenue.
With scientific breakthroughs coming and production costs dropping fast,
solar energy is expected to surge significantly in the next decade.
Till now, Japan, Germany and California have been the three largest solar
markets because of subsidies that rebate about half of the cost of a solar
installation. The annual growth rate of solar power is highest in Japan
(45%) and Europe (43%), where government programs help residents buy
rooftop units. In Japan, the cost of solar-power has dropped to a level
that nearly matches traditional sources. Even individual households that
use solar technology can sell excess electricity back to their utilities
for higher-than-market prices.
Solar-power is clean. It eliminates air pollution, greenhouse gas
emissions, coal or radioactive wastes. It is silent, and mostly unseen
- solar-power systems can be installed in densely populated areas.
There are no fuel costs, little or no maintenance.
Unfortunately, without subsidies, solar-generated electricity is still
about 10 times more expensive than equivalent power from old coal-fired
plants; 4 times more than natural gas; twice as much as nuclear; and
3 or 4 times as much as wind energy. But, technology is bringing prices
down very quickly.
The photo-voltaic cells used for generating solar energy in the past were
expensive, rigid silicon chips. Only techno-snobs were willing to show
off the ugly roof-racks. Today's thin-film solar-cells can be sprayed
by ink-jet nozzles in precise patterns onto sheets of plastic or roof
tiles. Not only does this cut costs, but the obtrusive arrays are gone.
There is no real infrastructure to encourage the use of solar power,
which inhibits its wider use. And many people would rather flip a switch,
than buy their own equipment to generate their own power and learn the
confusing technicalities. But solar power will become much more
user-friendly, practical and economical in the decade ahead.
Of course, the future of conventional fuel and power is being increasingly
questioned because of high oil prices, conflicts in the Middle East, the
threat of terrorism at domestic facilities and the kind of Enron-related
"rolling blackouts" that California recently experienced. Generating your
own, independent power suddenly becomes interesting. And as technology and
increased production brings down prices, and as the cost of traditional
electricity rises, solar power is becoming increasingly attractive.
The fast growing solar power markets are attracting venture capitalists
to fund startups. A lot of VC funding is moving into solar energy products.
Worldwide, 6 companies raised $64 million of VC money in 1999; 22 companies
received $114 million in 2001, and 26 companies got $277 million in 2003.
The VC bets are expected to top $0.5 billion this year.
Nanotech is coming on the scene, with Nanosys of Palo Alto working on
sprayable solar coatings for roofs, and Nanostellar looking to produce
cleaner, cheaper catalytic converters.

Stuck in the old industrial mindset
Growth, inflation, rising interest rates - the world seems stuck in an
outdated industrial-age mind-set. With all his intellectual power and
confusing financial techno-speak, even Alan Greenspan seems a little lost.
Today's economic thinking needs a big does of today's reality. Andy Kessler's
thought-provoking article in the Wall Street Journal is summarized here.
The term "output gap" is the difference between actual output and an
economy running at "full" capacity. Since the onset of the 2001 recession,
the US economy has theoretically fallen behind its full capacity by $4.4
trillion.
In the old "factory production" days, "full capacity" was when 3 shifts
were running, and new labor was expensive (too much training was needed).
It caused the familiar wage-price spiral which no one wants to repeat.
But the problem is that "capacity" and "production" are outdated,
industrial-age terms.
In the new techno-driven age, it cost's almost nothing to make another copy
of software. A high percentage of TV advertising is for pills, pills and
still more pills - which cost almost nothing to make. The high costs of
pharmaceuticals are in research and FDA trials, not factory production.
The incremental cost of another music download is zilch - the work went
into negotiating the royalties and setting up the system. Sending another
email costs me nothing but my own time. My computer sends 8,000 eNews
copies in less than an hour, and it costs me nothing.
It costs the telephone companies almost nothing for you to make another
phone call - once the equipment is in place. So, the land-line companies
are starting to offer unlimited nationwide calling, as a way to raise their
average billing. And the cell phone must look for new ways to get people
to spend more money - with video downloads, on-line chat, news services.
Even the service businesses have plenty of capacity. FedEx and UPS handle
the Christmas rush, with excess "capacity" the rest of the year. Wal-Mart
and COSTCO can easily multiply their shopping aisles with new buildings.
Harry Potter and Bill Clinton books can sell a million a week, without
depleting stock. Stock exchanges can handle hundred billion share trading
days without straining "capacity". Bankers have very little to do to
process another loan. Most movie theaters are multiplexed - there is a
24-theater AMC near my home, staffed by a handful of people.
In the knowledge age, there can never be an "output gap". And when
knowledge sources (research, design, engineering) is available somewhere
else in the world, at cheaper prices, the center-of-gravity of the old
industrial world is shifting.

The technology of big transistors - an inflection point
In these days of skyrocketing oil prices, a completely electric car
still not practical (low range, and you can't "re-fill" fast enough).
But "hybrid" cars are coming!
Since the internal combustion engine was first developed almost a century
and a half ago, the mechanical power was used to turn wheels and pump
fluids. With a hybrid, all the power from the engine (about 100 HP in a
small car) is used to generate electricity (about 70 kilowatts) to drive
electric motors distributed throughout the vehicle. Technology converts
the power from mechanical to electric, and electric provides the drive.
Everything is super-efficient, and power is never wasted.The battery is
automatically re-charged every time the car brakes, or goes downhill.
And the braking is electrical, brake pads and transmissions don't really
wear out.
Hybrid automobiles will sweep across the auto market in the next decade
or so, not only because they're cleaner and more fuel efficient but also
because they can radically improve almost every aspect of performance over
conventional cars.
The key enabling technology for the hybrid revolution is digital power
control, made possible by the power transistor, invented only about 25
years ago. Integrated circuits have millions of gates per chip. By
contrast, power transistors are single chips which handle kilowatts of
power. These transistors are big enough to control the propulsion of
trucks, automobiles and industrial machines. Sales of these big power
switches are already more than $1 billion annually, and will double every
few years for decades as more and more applications (like the hybrid car)
come on line.
Building a transistor switch that handles kilowatts generates an
inflection point which sets the stage for truly fundamental changes
in the infrastructure of the new industrial economy.
We will soon start to see the escalation of this revolution in the
auto industry. It's very likely that you and I will be driving a hybrid
electric car within the next decade, simply because it'll be cheaper
and better. And the old gas guzzler will be out of date.

Editorial - Fahrenheit 9/11
Someone said, "It's difficult to tell a saint, from a flake". Whatever
you think of Michael Moore (saint, or flake) you've got to admire his
persistence, his guts, and his moviemaking - albeit quirky and offbeat.
Moore's movie Fahrenheit 9/11 won the Cannes Film festival award
- though, of course, conservatives are complaining that there was
political motivation behind the award. In any case, it is grossing
more money at the box office than any documentary ever.
The movie is disturbing because of what it reveals about the characters
and motivations of the current US administration, the war in Iraq,
the deceit used to start the war, the media's naive endorsement of that
deception, the physical-emotional-mental horrors of the war in Iraq,
the corruption that comes with power.
The sight of flag-covered coffins returning from Iraq is disturbing,
especially considering that these coffins are strictly not allowed
to be photographed. It is sad to see the stumps of American amputees
coming home from the war, soldiers who gave their lives and limbs for
reasons that turned out to be "intelligence errors". The evidently
authentic footage of Bush is so candid and revealing that it's hard
to imagine how Moore got access to it.
Here's David Letterman's
"Top Ten George W. Bush Complaints About Fahrenheit 9/11":
10. | That actor who played the President was totally unconvincing |
9. | It oversimplified the way I stole the election |
8. | Too many of them fancy college-boy words |
7. | If Michael Moore had waited a few months, he could have included the part where I get him deported |
6. | Didn't have one of them hilarious monkeys who smoke cigarettes and gives people the finger |
5. | Of all Michael Moore's accusations, only 97% are true |
4. | Not sure - I passed out after a piece of popcorn lodged in my windpipe |
3. | Where the hell was Spider-man? |
2. | Couldn't hear most of the movie over Cheney's foul mouth |
1. | I thought this was supposed to be about dodgeball |
Disney (which owned the US distribution rights) tried to stop the movie
(beyond innuendos, no one openly admits why). The right-wingers are now
calling Moore a "domestic enemy". And as if on cue, the conservative
intellectuals are writing critiques that suggest it is empty nonsense.
This is NOT "just another Moore movie" - if it was, it would be easier
to ignore. No matter whether you're a Republican or a Democrat, if you
haven't seen Fahrenheit 9/11, you've just got to see it.
AFTER you've seen it, I'd like very much to receive your feedback!

Michael Pettengill [michaelpettengill@earthlink.net] adds insights
to my editorial on "the corruption of democracy" (eNews 1 July 2004):
"In a democracy, majority rule doesn't always produce a fair and just
outcome. The US Founders purposely made government cumbersome and limited
because they didn't trust decisions made in the heat of the moment.
"The USA is based on a rule of law, although in recent years it is clear
that many do not consider this to be an obstacle for implementing rule
of man.
"Certainly Bush doesn't understand the bit about not being a democracy,
but being governed by rule of law. Otherwise, he would have stated his
objective in Iraq as, and planned for, a rule of law. But rule of law is,
as the Founders intended, cumbersome and slow, so Bush has done what
he can to implement a rule of Bush.
"As to the reason for many not voting, the answer is simple, as any game
theorist or economist or engineer can tell you.
"If two competitors, say red and blue, are selling hot dogs on the beach
with each betting the other he will sell more hot dogs, the position both
will pick will divide the beach goers equally on either side. Each will
limit their choice to hot dogs, even if some customers might rather have
hamburgers, sausage, brats, fried pickles, because the bet is for the
most hot dogs. The people at the ends of the beach who hate hot dogs can
see no reason to bother to walk half way down the beach to buy a hot dog
from either the red or the blue hot dog stand. Both are equally
distasteful.
"Not willing to give up any possible hot dog sales, both red and blue
do all they can to prevent green from setting up a stand anywhere on
the beach selling brats, for example. Customers can never depend on
finding the green stand open, so many never bother searching.
"If all parties were to cooperate, a much larger group of customers could
be satisfied. For example, by locating red one quarter of the way down
the beach, blue at three quarters, and green in the middle. But the
tastes of the customers are fickle, and both red and blue might end up
losers. So we have the current system, with many unhappy customers and
the winner of the red-blue bet depending on the fickle choice of mustard
or relish brand. Do you prefer Heinz?"
