    Me Feinners all the way.

    As is everyone in reality.

    That's a great discretion of the anti-pylon brigade.


    a varyin mix of compo / nimbyish depending on the individual

    How many times have I dropped the hint ?

    And still no one from the anti-pylon side has been able to show any empathy for those already living with pylons. Me Feinners all the way.

    Do you realize at all what you are saying ?
    You are saying that anti pylon groups should spontaneously, without even being asked, start a crusade to have long term pylon suffering people compensated (I presume it's money you are suggesting not undergrounding).

    And I am arguing that really, all these people in the estates you have linked to, the people on here who are saying they live beside a pylon, are absolutely 100% positively free to join the mobilization if they so wish.

    Presumably these people are not children who need to have someone speaking for them ? :confused: Holding their hand, anticipating their grievances ?

    If you have a pylon on your land, or know directly someone who has, and are not happy with it, what are your options ? Sit on your ar$e and moan about it (or the fact you didn't get money), which is what you're doing on their/your behalf, or go out and do something about it ?

    Again I will repeat very clearly since you seem to skim over some bits :

    What do you think the reaction of an anti-pylons group is going to be towards a person who wishes to join, and who already has a pylon on their land ? Are they going to :
    a) welcome them and support them ?
    b) reject them and say "tough $hit" ?

    Because right now you seem to suggest that :
    a) the initiative should be that of anti-pylon groups to also militate for people who have chosen to live beside a pylon, or have not objected previously.
    b) anti-pylon groups are actively going to reject such a person with a "tough $hit" comment.

    I think you are just blinded by this self-victimizing stance (yes).

    What a paranoid, self-victimizing attitude.
    The bottom line CM is that other people in the same situation would have had the same opportunity to oppose the pylons as the people currently opposing them.
    I mean, Ireland has been a democracy and a republic long enough for people, whenever, to make a stand.

    And they did - there was opposition to rural electrification. Luckily the Government of the time was strong enough to reject the luddites who would make you believe electricity would leak from the sockets and kill you. Much as they should do now for those who think the view from their once off is more important then the national interest of secure energy supply.

    Your definition of Democracy is flat out wrong. It has nothing to do with people making a stand and simply means that the majority rule. This allows communities to make decisions that are to the advantage of the larger community and not simply in the interests of a minority. The exact opposite of your worldview where a tyranny of the minority can hold wider society to ransom.


  • Registered Users, Registered Users 2 Posts: 6,705 ✭✭✭Mountainsandh


    How disingenuous.

    My point is obviously that anyone can speak out.

    edit : I think CM is focusing on urban dwellers having to suffer pylons.
    edit again (don't want to multiple post) : and your link refers to the first switching of lights, the first connection to electricity.
    The current debate is not about just an upgrade for say, villagers use (if we were to take the villagers in your link), but also to accommodate wind farms generation/power for export.

    An important point lots of people are missing when discussing future energy consumption needs is how long a project like this takes from initial studies through to final commissioning. I've been told the average worldwide is something approaching the 12 year mark, and then the line itself might expect a 40-50 year operational life. For this reason you pretty much have to sensibly plan much past the projected energy demands at time of project completion. Why do you think we haven't had to build any new lines of this scale in a while.

    Year on year energy demand growths of 1-2% may sound small but give it twenty to thirty years and that becomes a large increase in energy consumption. Factor in things like electric vehicles and demand could easily grow higher than that.

    You can add capacity on the existing pylon system if that is an issue - the pylon projects as envisaged are totally out of kilter for a country with a population of less than 5 million. Again Eirgrid have consistantly referred to wind energy export projects as the basis for these plans to drive massive new pylon infrastructure through every corner of the country(the current plans are just the tip of the ice-berg with a large number of other major pylon projects in the pipeline). The idea that our countryside should be sacrificed and turned into a wasteland of pylons and giant wind turbines to facilitate the Brits who don't want such things in their rural areas is abhorrent. In any case it is increasingly doubtfull whether this wind export plans are even viable given the UKs turn to Nuclear and the EU plans to revise its renewable energy planes on the back of rising energy costs on wind dependent grids and failure of wind to lower CO2 emmissions in countries like Germany.

    Already been done. Lots of cable upgrades in recent years. But there is a limit to how far you can go. Especially when you've only got a skin depth of about 9mm in Aluminium at 50Hz, which means there are limits to how much power a tower can handle.

    http://europe.nxtbook.com/nxteu/zahra/em_20121011/index.php?device=accessible&pg=25&cid=share
    The Inchicore-Maynooth 220kV Double Circuit Line is about 19km in length and was originally built using 600mm2 steel reinforced aluminium conductor, known as ACSR. Over the years, industrial and commercial development near the lines has reduced clearances and the maximum operating temperature to 60°C. This imposed significant load capacity restrictions on these lines and limited their effectiveness.

    Upgrading both lines by replacing the existing ACSR with newer high-temperature low-sag conductor types (HTLS) would significantly increase the capacity of the line to over 800MVA in winter and an operating temperature of up to 210°C

    Pylons pose no major health threat to humans, says European Commission

    Electromagnetic fields from pylons pose no major health threat to humans, according to a review by the European Commission.

    Don't bother, these Luddites will ignore any real research and go by local rumour instead.

    They will take any illness near a pylon to be the "proof" they need.

    We had less than 3 million in 1971, less than 4 million in 2003

    Go back to 1841 and the population of the 26 counties was over 6.5 million.

    The skin depth is irrelevant to that point though. There will be a limit regardless of skin depth.

    Pardon? I'm not following you I'm afraid. I post a link to a news piece about EU study on health effects and you say it is proof it is about turbines??

    IIRC you have a material interest in the area of wind turbines.

    Why is this the cry, Someone who understands the need for the upgrade suddenly is working for or part of government.. Can you not believe normal people could just disagree and not have an agenda ? it’s getting boring the amount of omg Enda is that you or whatever. And nice to see the E.U debunking that CM but I'm sure they will spin it and say there information is wrong and another group that has an agenda is correct.

    What needs to happen is a review of the business case, not nonsense about compensation and under grounding. We either need them or don't and I think enough of a question has arisen over the business case given the length of time since is was signed off.

    The McGuinness thing will find what every other analysis has - no discernable health implication and the costs of underground are stratospheric. We need an economic analysis though as to whether the basis still stands. It goes ahead regardless of the Nimbys if the case still exists.

    Exactly.

    It's just that you hit that limit a lot sooner since only the outside 9mm of the cable carries the bulk of the current.

    Quadruple the cable cross section area and you only double the current carrying capacity


  • Closed Accounts Posts: 13,376 ✭✭✭✭Bruthal


    It's just that you hit that limit a lot sooner since only the outside 9mm of the cable carries the bulk of the current.

    Even without skin effect, the outer half of a cable would carry 75 percent of current. The skin effect is a little different than that of course.
    Quadruple the cable cross section area and you only double the current carrying capacity

    When a cable goes from 600 square to 1200 square, the effective skin effect area is 70 percent larger. So it would be expected to have a 70 percent higher capacity.

    However, a cable doubling in cross sectional area cant dissipate heat twice as fast as one half its size, since its outer surface has not doubled, so it is this, as much as skin effect, which reduces the capacity increase:size ratio.

    Two smaller cables in parallel are often used instead of one larger one, to get around the above limitations.

    I have a feeling you are confusing me with someone else and would ask that you reconsider that remark.

    As a whole..the argument(for having these 400kva power lines anywhere near peoples residences) is about as strong as the "smoking doesn't cause cancer" brigade.

    And as weak as the hope that having unprotected sex with an AIDS patient won't give you AIDS.

    err no them 2 have actual peer reviewed scientific evidence to back them up.

    Unlike EMF causes cancer because I read somewhere on the internet. Or paper written by doctor spock says so

    Odd that you don't believe the EU when it's said to be safe and no issue.

    The EU mentioned increased risk and that's enough for me. I'd take EU reports with a pinch of salt anyway.

    Love the way people get worked up about a potential health risk, when living in the country carries some very real health risks like a much higher chance of dying in a road traffic accident.

    we don't know if anyone has had suffered anything other than a nocebo effect when living in the vicinity of pylons,

    But we do know that there have been hundreds of excess deaths in rural areas from road traffic accidents over 70% of the total.


  • Registered Users, Registered Users 2 Posts: 6,705 ✭✭✭Mountainsandh


    WHO are due to release a report of their own mid-year I think, that will be interesting. Haven't read the EU report yet, great if it took into account studies with a long enough scope to make a real assessment.
    I still wouldn't like a pylon too near to my house.

    From my point of view a scheme of that scale is still a mistake of course.


  • Registered Users, Registered Users 2 Posts: 6,705 ✭✭✭Mountainsandh

    And potentially a lot less deaths from repeated exposure to fumes, stress related illness, and anti-social behaviour, all harder to quantify.


  • Closed Accounts Posts: 2,435 ✭✭✭Stavros Murphy


    Remember mobiles giving you cancer ? and all that nonsense most people would not be able to live without there IPhone and so on now

    They're still not too sure on that one btw. And pylon love depends on how you react to being near them. I have to the odd time for work and the fcukers give me a raging headache. And mobile masts? I used to work training the operators on that scene and the time allowed close to the mast is very limited. Why's that, I wonder? ZZZZTTTzzztttZZZtt.

    High level microwave radiation near the tower it's self, completely different kettle of fish to EMF. And it's only Dangerous at short distances e.g next to the tower why they have fences and so on next to them. There are always safe levels of exposure taken into account in regards to how close to your house they are for example just like Pylons.... If people are that scared of Mobile phone towers better chuck out your microwave as well. And your mobile handsets. The whole you cant prove it’s not safe argument I find is used for far to many small groups opposed to progress. If these things were dangerous there would be peer reviewed papers highlighting them and not some spurious paper produced by some random/untrained person who thinks their a scientist.


  • Closed Accounts Posts: 24,461 ✭✭✭✭darkpagandeath


    Them two do. Do they?

    Smoking has been proven to heighten/cause cancer yes.
    As for the other one again that would massively increase your chances of getting said disease.
    I'm sure you can find the information on the WHO site. I'm not finding information for someone else's argument. As it's completely irrelevant and grasping at straws comparing pylons to those 2 points


    Not sure what you're getting at here. Some attempt at an insult me thinks

    Nope just saying the evidence used by the other side is never reputable and a spurious paper from either none scientist or lobby group.

    The EU mentioned increased risk and that's enough for me. I'd take EU reports with a pinch of salt anyway.

    You say the EU say it increases the risk and then make a sweeping statement about not listening to EU reports ? That's not contradictory at all

    But underground is fine yes ?

    If so why ? The EMF would be higher I'm guessing if undergrounded as their not going to stick them as far underground as they are up in the air on cables as they will need to be repaired. I think people misunderstand putting something a few feet underground will solve the EMF problem they perceive. Maybe they don't understand the Earths massive EMF comes from the earths core. And guess how far underground that is
