Here's an interesting story from www.cattlenetwork.com about farmer opposition in Kansas. Personally, I think its premature to say hvdc powerlines do not produce stray voltage that harm dairy cattle milk production. I'd be curious about the data and studies.
It's amazing just how much is written about stray voltage from hvdc powerlines being corrosive and harmful to pipelines. Sure, the Electromagnetic Field issue is different with a DC powerline as opposed to the traditional AC powerlines, but stray voltage is still an issue, as the pipeline industry.
A friend in the pipeline industry explained it to me this way. A pipeline wants to be the most negatively charged thing in the ground. Like a direct current powerline, the gas is flowing one way and can create a negative charge. When a hvdc powerline is much more negatively charged. When there is short or stray voltage (and there always is some to a varying degree) , the powerline can be a far greater negative charge than the pipeline. To put it in simple terms, this reverse flow of charged atoms away from the pipeline causes to pipeline to corrode.
It's amazing how little documentation there is about the potential health hazards hvdc is to people, but there is so much written about the hazards of hvdc to an inanimate object like a pipe.
Just google "hvdc corrosive pipeline"
The internet is littered with studies like this one.
One last comment about pipelines. Is the Rock Island Clean Line really going to locate next to the Northern Borders pipeline or is the proposed right of way going to change again for the "safety" of the pipeline? Would RICL desire to place the pipeline in the middle of the field, well away from the fence line for the "safety" (potential future liability) to the pipeline?
But no....according to "clean" line there is no hazard to people or dairy cattle. Pardon me, I am having difficulty suspending my ability of disbelief to accept the claim stray voltage from a hvdc powerline is a problem to pipelines but not to dairy cattle.
Next week I'll probably read claims from hans&franz that living near a hvdc powerline cures gastroenteritis.
Ok, I have a question. Suppose a HVDC powerline (RICL) is running parallel to an existing natural gas pipeline (Northern Borders). Because of stray voltage issues and pipeline corrosion, the powerline elects to seek a right of way 1000 feet away from the pipeline.
Sure the powerline only wants to purchase a 200 foot wide right of way but they are effectively recieving a 1,200 foot wide right of way. That 1,000 feet between the two right of ways is effectively useless. You can't build on it and develope it. No other company will seek a right of way between to two right of ways.
If there is a 1,000 foot gap between two right of ways and the HVDC powerline is only buying 200 feed width of right of way, the powerline company is effectively recieving the extra width that is five times larger than the 200 foot right of way for free.
If a powerline company thinks they can get away with this, they better think again. Powerline executives better ask themselves this simple question. What is a local county court going to determine in an eminent domain case? I'll give you a hint. The court is going to say buy the real right of way 6 times larger than the company intends at a FAIR price for a right of way.
The damages to the property value isn't going to be a few poles. It will be much much wider than 200 feet.
I am speaking from personal experience, here. Another farm of my family has 3 or 4 pipelines next to each other plus a 100,000 volt powerline. Two of the pipelines and the powerline lies on our property. The other pipelines are on the neighbors property and come up to a quary pit. When they start taking up more than their right of way, land gets used up quickly.
There is literally no more room for another right of way. To the north is a enormous pit mine. To the south are some massive hills, farm buildings and houses. The next company that thinks they need to put a right of way through this corridor is going to have to think again. The right of ways will have to start piling up on top of each other. There is no more room.
Now I seriously doubt RICL will change their mind and move the powerline to the south of the Northern Borders pipeline and on to my property. There is a mountain of overburden from a gravel pit a few miles to the west of Prairie Center. RICL will have to go to the north of that pile and it is unlikely they would the cut back south and affect me directly, but if they did, we wouldn't be talking about a paltry $8,500 per acre for a 200 foot right of way. We would be starting at $45,000 an acre and the right of way would start at the edge of the Northern Borders pipeline right of way.
If RICL or Duke or any other powerline company thinks they can just take more land than their allotted right of way, they had better think again. We've grown tired of this nonsense.
