I certainly wasn't suggesting commercially using such. But it's pure steady DC. It has it's uses.

My understanding is that a major savings is actually the cost of the land right-of-way leases since it can be significantly narrower for a DC monoline.I think that any new installations that require a long distance transmission are going to consider DC, there are incredible savings to be had, with the loss of one conductor and the much reduced losses.

Was the necessary semiconductor technology available even back then? And if so, why has it taken so long for it to become more popular?The 3 HVDC conversion stations we presently have were built in 1968.
Presently there is a total of 5 Hydro stations with 15 Hydro generators capable of producing 5,700Mw.
Another new one in the works.

There are environmental considerations, especially when traveling through arboreal forest.My understanding is that a major savings is actually the cost of the land right-of-way leases since it can be significantly narrower for a DC monoline.
They used Mercury Arc Valves on the original systems. We had similar AC/DC plate voltage converters using Mercury Arc Valves in some of the original HF transmitters we worked on.Was the necessary semiconductor technology available even back then?

DC is just a very low frequency AC signal.AC is just manipulated DC. You can think of DC as male and AC as female. There are thousands of studies confirming this theory and these characteristics.
Obviously that's a perception problem on behalf of your own personal biases towards what you read.Also, you speak like engineers and business people running the utility are stupid.
Yea we have a large DC transmission line going through our state not too many miles south of me. It's been there a long time now.It is generated in the usual way (AC) the conversion takes place either end.
Yes, over many Km the saving in the one less line is also considerable.
ABB were one of the first to install in the west quite a few decades ago.

I agree. The speed of the investment can be faster if the benefits still exist when you must invest in more infrastructure before the current infrastructural has reached it's life-cycle.If there is money to be save, they will invest.
Yeah... but then they'll buy it at a price equivalent of a $(4x4)^(4x4) ....Even the government, will wait 5 years or 60k miles before getting a new 4x4.
Oh my... Our governments must be related... welcome to the family!GSA, the supplier of the U.S. government would rather buy new tires than do a front end alignment.
But, running 5 years and selling it to the public, individual A obtain the Vehicle at reduced price. Then B purchases it and runs the rubber off and put another set on and sell it to the next guy C, who purchases it at an even more reduced cost.GSA, the supplier of the U.S. government would rather buy new tires than do a front end alignment.
You get it by the time it reaches me. I pick it up for $1000 dollars then drive it into the ground then sell it for scrap metal.
If the project is being done by BC Hydro or in Ontario, I will be questioning the numbers a lotIn engineering speak we call this the point of deminishing returns - but thanks for the math.
Also, you speak like engineers and business people running the utility are stupid. If there is money to be save, they will invest. If there is no money to be saved, they will find another location to spend the money. I'm sure you will fire back with various conspiracy theories and superficial examples about unprofitable projects but cash is king and grid reliability or other less obvious goals impact the cash a utility makes. I'm certain their decisions have merit.
That's your prerogative. Do you care to share why? Do note that my statement included: "...reliability or other less obvious goals".If the project is being done by BC Hydro or in Ontario, I will be questioning the numbers a lot
Yes, it was a bit of a gut reaction...That's your prerogative. Do you care to share why? Do note that my statement included: "...reliability or other less obvious goals".
I await details.
