Schizo Hydro Power Plant Does Both 50Hz and 60Hz.

[Watson A.Name - \Watt Sun, the Dark Remover\]

WOW! 750kV AC! -+500kV DC! The 2nd & 3ed pages give pics and info on
the generators, etc. Each of the 18 generators puts out over 700MW,
which is about as much as half a regular or nuclear generating station!
Mamma mia! Two separate power plants. Rectifiers the size of
buildings! Everything's so HUGE!

Many environmentalists don't much like power dams either & perhaps with
good reason. For example, by the time the Colorado River gets to the Gulf
of California there isn't much water left. I guess that screws things up
for the whales & the Mexicans who live there. But I guess that is OK as
long as the desert is kept watered for those with
money. JLS

All bow down to the gods from California!

We hear the same reasoning from the NYC folks. They say we should be
damn happy to landfill their trash because NYC gives *so* much to the
WORLD!

Y'all can keep your cotton California. We south easterners were growing
cotton long before California was "liberated" from Mexico... And we will
contimue to do so long after California sails off into the sunset, and
sinks to the bottom of the Pacific Ocean.

Prior to California's great experiment in desert beautification, we used
to have great variety in our vegetables and fruits. (year round too!)
Now, we get 3 kinds of apples, tasteless tomatoes, mushy pears, strawberries
luciously red on the outside, and white on the inside, leathery
green beans, mangoes that go straight from green to rotten... Come to
think of it, most of the fruits we get from California go straight from
greem to rotten. Definitely worth the drying up of a river!

I guess there has been one major benefit to California's "liberating" all
of the water from the Colorado River: The irrigation has rinsed the selenium
out of the desert soil, and poisoned the ground water (formerly the only
safe source of potable water in your desert.).

Nonsense. Mexico is part of the treaty settlement covering the
dispensation of Colorado River water. Mexico has a guaranteed
portion, and is also guaranteed low-salinity.

I don't know if it's specifically RO, but we DO have desalination
plants, plus specific electronic controls at the farm irrigation level
to stop the feed before overflow... I worked on some of the metering
systems that fine farmers based on overflow.

There are no gods in California (well, excepot for me maybe..). There
are just a bunch of huge agribusinesses that run farms out there in the
desert that grow most of the produce for the U.S.

They said on TV that some of these businesses are hurting for labor
because they are having a hard time getting illegals for their job
openings.

Sure you were. It's just that California grows so much more of it.

No, you got it all wrong. The western side of the San Andreas fault
will still be there, while the east side will sink into the ocean! [

Do you mean *real environmentalists* or NIMBYs ?

Seeing the same trouble here in the UK with 'wind farms'.

It made an area inhabitable that previously wasn't. I guess you can debate
the merits of that til the cows come home.

I've heard about that selenium problem. Nothing to do with the power generation
itself of course.

[Watson A.Name - \Watt Sun, the Dark Remover\]

The 500KV DC intertie between Celilo, OR and Sylmar, CA
transmits 3.1GW from our dams on the Columbia River to Los
Angeles. Another more-or-less parallel AC system carries
an additional 4.8GW to San Francisco and LA. The HVDC line
started in 1971 at 400KV and 1.4GW and has been upgraded
twice.
Awesome!

They are replacing the old mercury-vapor rectifiers with
"Siemens light-triggered thyristor valves"
http://www.transmission.bpa.gov/PlanProj/Transmission_Projects/photos.cf
m?page=CM
I'd never heard of such things before, but here is a picture of
one the size of a Japaneese apartment building...
http://www.tic.toshiba.com.au/website/newtic/hvdc_lttbimg.htm

Yeah, like I said.

I've heard that the reason for DC was because of transmission
losses at 60Hz. According to my calculations, the wavelength
of 60Hz is 500KM. So the length of the transmission line is
1361KM which makes it 2.72 wavelengths @ 60Hz. How
does that work?

At a half a megavolt RMS, the corona discharge is what causes a lot of
losses. That's 1.414 MV peak-peak. Using DC reduces the voltage.

IIRC, the Sylmar end of the line is inside a humongous cage of
chain-link fence next to I-5. Just across the interstate from there
are those two huge pipes that carry Colorado River water over
the hills into the LA basin. The ones we've seen in movies
("Chinatown"?) http://you-are-here.com/location/aqueduct.html
is an early pix from back when the first aqueduct was built.

Wow, Gigawatts. Our newest campus is right beside those high towers.
Must be less than a couple hundred feet away. Oddly, I never see any
birds fly up and land on those lines. But the pigeons are always
landing on the 66kV lines around town.

Well, the dam serves two purposes, irrigation and power generation.
Without the dam, you wouldn't have the selenium problem.

They should extract it and use it to make the next set of replacement

To be accurate - you *couldn't* have the selenium leaching problem.

How the water is used doesn't itself make the use of a dam wrong for
power generation in any way.

If it's the one I'm thinking of - covered by the UK's excellent Open
University TV broadcasts http://www.open.ac.uk/ - wasn't that where the
birds had problems with thin shells and early mortality of their young ?

p.s. the Russians created a great ecological disaster by using irrigation
to produce cotton in the area of the Aral sea. In that case the
fertilisers - insecticides etc ran off into the inland sea and basically
killed it. The wind now also blows about toxin laden dust too causing all
manner of health problems in the area.
