A guy in Florida quoted 48 years pay back time. I ran
the numbers for my home - over 40 years, and I pay 13
cents per kwh. A 2 kW system costs $15000. Assuming
an average of 8 hours per day of 2kW per hour, that
solar system would give me 16 kWh. I pay 16*.13 or
$2.08 for 16 kWh. Works out to 19+ years for payback,
if you don't count on mortgage payments for the system.
Add that in, and the cost of a $15000 system is
much worse - over 30,000 in a 25 year, 7% mortgage.
You have to take into account that the cost of a kWh from
the grid in 25 years will be a LOT higher too, if there
still is a grid during and after WW3 that is.

I don't blame you for being paranoid about WW3, if you're from Holland.
History has treated those countries poorly during the last WWs. But
then, who cares if there's a WW3? I'm more concerned about the next big
earthquake. Some scientists are predicting a big 6.something earthquake
in the Southern Calif. desert before Sept. I hope so, 'cause some of
these immigrants might consider going back to their point of
origination.

Yea, every place has it problems, here it is the water level, and dikes
-so flooding-.
Those imigrants are a workforce, illegal immigrants behave usually pretty
well to avoid being exposed.
I personally think they have equal rights as the native Americans who stole
the land from the Indiens (spelling?).
Zero rights? Or the right of the strongest.
Was it not Reagan who pardonned most of them in California?
Then they started paying taxes....
Was not California short of cash?
JP


FINALLY! I've figured out Jan's source of news and historical
information... comic books ;-)

Wrong again, as first hand experience working in California
I KNOW how it is.
I ALSO know what a jail full of illegal Mexicans looks like from the inside.
So you better stop joking, I probably know US better then you.
And no I am not a Mexican.
That was the south border, I can also tell you about the north border.
Now go and dream on, dream dream dream the US dream my friend.

Have you seen the windmill "farm" west of Indio, California (on I10) ?

HUNDREDS of large windmill AC generators.


Is that the farm between LA and (around) Palm Springs? I drove
through there ~five years ago and was amazed at the size of the
wind-farm(s?) and the number of turbines that were stopped.

I believe the name of that farm is "San Gorgonio Pass" and has
about 3500 turbines. The "Altimont Pass" farm has another 3500
and an even larger one in "Tehachapi Pass" (5000). (there is a
common thread in these names ;-)

Altogether something like 1% of CA's electricity comes from wind.
That's impressive, though hardly scale able to 100%. The CA
mountain passes hardly indicate the viability of wind power in
the rest of the country/world.

I haven't been able to determine if the stopped units were off-line
for repair, or simply off-line based on grid needs. I've *never* seen

From my conversations with wind-energy proponents after seeing
the farm, they seem to be off-line for maintenance, and the
required maintenance wasn't deemed profitable. No subsidies for
maintenance, only development. This may have changed since the
generators have become cheaper, perhaps even profitable. ;-)

I think, other than the pollution, the costs are included in the
overall running cost (dead miners, etc. etc.). The pollution is a bit
harder to figure, but modern plants are pretty clean. I live close to
a big thermal plant and the left-wing newspapers have been running
pictures of the stacks (usually with evil lighting) saying that
"smoke" is rising blah blah. They've dug up old pictures with all 4
stacks running, and it's usually running at 25%; never more than 50%.
Of course it's mostly steam and some CO2- on a clear day you can see
nothing in the air discoloring it, just the refraction from the heat
and steam trails that rapidly dissipate. The stupid new gov't has been
making noises about closing the thermal plants *AND* the nuclear
plants- I don't know where they think the power would come from (maybe
we can buy it all and export the problem to less "responsible"
people). Bleh. Even with conservation measures and some
deindustrialization, population is growing at a healthy rate, and so
is consumption.

Highland Ham April 19th 04 12:11 AM

Last month I went to Palm springs for the Faire, and there was no
noticeable difference in the numbers of windmills in operation.

=====================
Having seen these machines near Palm Springs ,they seem to be rather small
and of an older design.
Modern machines are much bigger (up to 2 MW rated capacity) and more
reliable.
In the Netherlands they are now planning a number of 2MW machines offshore
,approx 8 kms off the coast placed on seabed based stuctures.
Their designers are focussing on minimum maintenance ( only once every 3
years) .

To date land based machines produce on average only 16% of their rated
capacity ,due to periods without adequate wind and to technical outage /
maintenance. Yet they seem profitable. In the Netherlands many farmers have
them on their land ,especially
in the northern provinces.

That's silly economics. I do not have to take into account the
cost of electricity in 25 years. I can wait. Solar cells are
becoming cheaper too. When the cost of the solar cell is less
than the cost of power from the grid I can switch, saving all of
the negative amortization inbetween, and have a *new* system in
25 years, just as you're in need of replacing yours. ;-)

My guess though, is that solar cells for the individual will
never become cheaper than power from the grid, since the power
company has access to the same technology and a *lot* better
financing possibilities. ...and they don't have to have the pay-
back in my lifetime.


They have access to the tech, BUT, they also have to maintain the
distribution system. Since my electricity has been unbundled,
roughly half of my cost per Kwh goes to the distribution co., not the
producer. Ice storms, drunk drivers, blown line fuses all cost money.
As well as the personel and associated benefits packages,
transportation costs of materials, etc. for maintaining the lines.
All this is avoided cost on home solar.

And...
www.solaraccess.com/news/story?storyid=6482

talking about a new discovery:

"A solar cell with the simplest possible physical structure could
achieve 50 percent efficiency or better, far higher than any yet
demonstrated in the laboratory."

It isn't cost effective for most of us yet, but the tipping point
is coming.

You have to take into account that the cost of a kWh from

That depends to some degree what you consider the "costs" of burning coal
are.


I think, other than the pollution, the costs are included in the
overall running cost (dead miners, etc. etc.). The pollution is a bit
harder to figure, but modern plants are pretty clean. I live close to
a big thermal plant and the left-wing newspapers have been running
pictures of the stacks (usually with evil lighting) saying that
"smoke" is rising blah blah. They've dug up old pictures with all 4
stacks running, and it's usually running at 25%; never more than 50%.
Of course it's mostly steam and some CO2- on a clear day you can see
nothing in the air discoloring it, just the refraction from the heat
and steam trails that rapidly dissipate. The stupid new gov't has been
making noises about closing the thermal plants *AND* the nuclear
plants- I don't know where they think the power would come from (maybe
we can buy it all and export the problem to less "responsible"
people). Bleh. Even with conservation measures and some
deindustrialization, population is growing at a healthy rate, and so
is consumption.


I assume you are talking about coal fired plants? They release particles
as well as mercury and radioactivity. There is no clean power.

I wonder if they shouldn't be replaced, that's prime wind territory.

In the Netherlands many farmers have them on their land, especially

Do they rent the space to the wind-generator owners, or do they each
install and maintain them themselves? Is there a subsidized rate for
the sale of electricity to the grid?

Actually, this probably has more to do with the great public defender they
are likely to get.

You haven't got the perspective! The sleep on the streets and
hang out at businesses hoping to be offered work and have
destroyed whole neighborhoods.


Well, I lived down in Orange County CA for a long time. I must admit that
there are some offensive things going on, but most of the illegals I know
about are not the quintessential Hobos of our modern society. Too much risk
in coming above "the man's" radar. They hang with their extended families,
and out in the farming districts where they get seasonal work. Big
population in Colorado for some reason.

The problem is spreading and it is
really bad the nearer you get to the boarder. Farmers along the
border have their crops and equipment stolen or spoiled and have
to maintain a security patrol to keep their homes from being
broken into. These people are criminals and do not respect any
laws.


Beg pardon. These people, except for course for the drug mules that we pay
to bring us our cheap drugs, are the brightest, best, and most ambitious of
a seriously abused population. We might solve 90% of our problems, at the
cost of a bit more expensive lettuce, by making them semi legals and
preventing their abuse.

.... (subject. Paying taxes.)
Not then, nor now! They are a major burden on the state to the
tune of about $4b a year!


Whew! Is that all? They are responsible for around 12 billion in company
proffits, of which they get around 3 billion, and out of that they pay
around half billion in sales taxes. Actually I expect their employers
collect federal and state tax from their salary, and pay it to themselves. I
think that overall our illegal emegrants likely provide us more benifit than
cost, and on top of that they are such an easy target for racial and
cultural hatred. Easy to blame our total failure to provide for our own poor
by calling them all illegals because some few are, horror of horrors, unable
to get legally admitted to our official version of heaven.

BTB, I just made up the numbers for the heck of it. Sounds reasonable to me,
so find better ones.

Reagan was Governor from 1967-1975, didn't think illegals were on the radar
back then. During his presidency in the 1980s they were noticeable. I lived in
LA til '86...so thought you were referring to that time period.

No. The tribes "owned" the land they could defend with their ferocity,
cunning, and a sharp stick or flint ax. They did not farm as individuals but
as extended families, so they had no need to own the land as individuals.
The horse, and the steel blades changed all that quite rapidly in historic
terms, well before the settlers started to sweep across the country.

Rather small?!!!! You call 350kW or more with blades 150 Feet (45m)
long *SMALL*????

Modern machines are much bigger (up to 2 MW rated capacity) and more
reliable.


Even bigger!

In the Netherlands they are now planning a number of 2MW machines offshore
,approx 8 kms off the coast placed on seabed based stuctures.
Their designers are focussing on minimum maintenance ( only once every 3
years) .


To date land based machines produce on average only 16% of their rated
capacity ,due to periods without adequate wind and to technical outage /
maintenance. Yet they seem profitable. In the Netherlands many farmers have
them on their land ,especially
in the northern provinces.


I'd like to know what has to be done to get the generated power back
into the grid.
