I don't know the funding history of the original copper and microwave land line system, but the defense department did not pay for the cellular a network in place today, which was funded by commercial debt and user fees. So too the fiber optic network replacement of the copper and microwave landlines, though the FCC offers some subsidies to accelerate more "broadband" access.Windadct said:The entire US telecom system was built on subsidies as a part of national defense,...
Perhaps, and perhaps it is a tool to promote cronyism.but it is a tool to promote change.
Ah! Hahahahahaha!Windadct said:Found this List of Siemens projects - seemed to relate. Sorry - kind of a large PDF.
I'm glad I'm not the only one:OmCheeto said:But, as I've said, this is way too much information for me to process in just a few days...
It really is, quite complicated.However on the issues of Subsidies - it REALLY is not black and white, examples,...

anorlunda said:Here is an interesting item I would like to share. It seems that China has drastically pushed the boundaries of power transmission grid operations. They boldly go where no man has gone before.
How and why?
They are doing things that old timers like me never imagined. Specifically, they challenged the catechism that increased interconnectivity of the AC grid is more reliable; a principle we used for more than 100 years. Hats off to them.
- The combination of geography and demographics leads them to place large generation resources very far away from the loads where consumers live.
- Excessively long transmission lines make HVDC attractive as a competition for AC.
- Excessive number of HVDC lines brings new operational challenges and opportunities, which they seem to be managing just fine.
Not so much. Check the IEEE reference supplied by the OP.Guy Madison said:I think they are just spreading the pollution around...
...It operates more than 20 HVDC lines that deliver hydro, coal, and wind power from the nation’s interior to its eastern megacities. In southern China, five HVDC lines carry about 26 gigawatts of hydropower from mountainous Yunnan province to the coastal factories of Guangdong, ...

Also, the pollution harm from coal is not linear. That is, the collective harm from particulates and smog is not as great as when it's concentrated, say, near a city. So it may be true that the same amount of particulates are 'spread' around, but the harm is not the same.
I think you missed my point about concentration. Locating a coal plant in rural area is someone else's problem, but it's *less* of a harmful problem even on the individual basis, given the next plant is, say, 250 miles away instead of 10 miles away, possibly nobody lives within a couple miles of the plant in a rural area (unlike urban coal plants), the rural stack is, say, 100M tall instead of 40M in an urban area, etc.Guy Madison said:Sure.. but when it's away from a major city.. pollution becomes someone else's problem. Major coal plants even in the US are located away from major cities for the same reason, and it's so much much easier to offload coal trains in sparsely populated areas. Think of all the coal plants that line the interstate 90 corridor from Montana to Chicago.
