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

I read in alt.binaries.schematics.electronic that "Watson A.Name - \"Watt Sun, the Dark Remover\"" wrote (in ) about 'Schizo Hydro Power Plant Does Both 50Hz and 60Hz.', on Wed, 6 Apr 2005:

Especially the methane emissions from the decomposing vegetation in the lake. TANSTAAFL!

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

?? The cotton in the shirt on your back was very likely grown in the Imperial Valley, watered with that very water that came from the Colorado River!

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.).

All in good fun,

my trash goes to Pennsylvania via Route 78.

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.

Nonsense. The best cotton is Supima cotton, grown right here in Arizona ;-)

The straight green-to-rotten stuff comes from Mexico and various South American countries.

Hence the RO plant on our side of the border...

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.

A friend of mine headed the hydro department of a major US equipment manufacturer when this was being bid in the '60s. He told me that the original concept called for a dual

He also told me that the required bribes were spelled out in the bid documents. I don't think any US company got a part of this mega job (maybe Harza Engineering in Chicago was the designer, I don't recall). The various contractors probably went thru hell... talk about trying to serve 2 masters.

In spite of other comments here, this is about as clean as power comes at this scale.

BTW, my friend did go on to design some of the largest hydro generators installed in the US, a fitting cap to his career.

LOL, The red line on the floor indicates the border of Brazil and Paraguay.

I wonder if you have to go thru immigration to walk from one end to the other. Is that a red line I see on the control room floor? Yes, "The control center of the 18 generators Left half of it (in Brazil) controls the 60 Hz units, right half  (in Paraguay) controls the 50 Hz units." I'd bet that the floor area on each side is the same to within a small fraction of a sq meter. Maybe even the number of meters and control switches is the same. Lawyers and politicians should be required to leave the property when any serious science or engineering is being done.

LOL#2, Upon looking up the spelling of politician I find this : One who seeks personal or partisan gain, often by scheming and maneuvering.

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.

will

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! [:-)

Yeah, using that very same Colorado River water!!

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.

They are replacing the old mercury-vapor rectifiers with "Siemens light-triggered thyristor valves"

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

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"?)

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.

Graham

In Ireland, the border between the North and the Republic passes through some ppls' houses !

Graham

Awesome!

Yeah, like I said.

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.

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.

Look up Kesterson Wildlife Refuge.
