Argyll's online broadsheet.

Newsroom, If you read my first comment on this …

Comment posted Wind energy may be controversial but the logistics and the skills are mesmeric by Scots Renewables.


If you read my first comment on this thread you will see that it was to say that China has begun to clean up its rare earths industry.

One of the consequences will be less for us – or we have to start mining our own.

  • Wind turbines consume relatively miniscule amounts of electricity from the grid Malcolm. The yaw motors operate only when the wind changes direction, and the blade feathering controls only come into play when the turbine is already at maximum output.

    All power stations consume electricity from the grid for heating, lighting, security systems etc.

    If a period of low temperatures is combined with a low-wind condition, a wind turbine may require an external supply of power, equivalent to a few percent of its rated power, for internal heating.

    This Wikipedia article gives the example of the St. Leon, Manitoba project. It has a total rating of 99 MW and is estimated to need up to 3 MW (around 3% of capacity) of station service power a few days a year for temperatures down to –30 °C.

    This factor obviously marginally affects the economics of wind turbine operation in cold climates. However, Manitoba is in Canada where winters are much colder than they are in Scotland.

    Electricity is not used to turn turbine rotors, this is just a daft conspiracy theory with no evidence to support it.

  • What’s your view on the moon landings Keith?
  • I laid it out so a child could understand it – and none of you would say – OK – now we understand Malcolm’s point of view.

    That is because your figures are unsubstantiated, plucked out of thin air and have been thoroughly refuted more than once on here.

    I know the Doc is too polite to complain, but your pathetic personal abuse is not the way civilised debate is conducted. You really do seem to have lost the plot Malcolm – time for a wee lie down perhaps?

  • 90% is, frankly, rubbish.

    Between 2005 and 2009 the UK nuclear fleet never exceeded 80% load factor in any year, and in 2008 it was below 50% (figures from DECC [table 5.10, page 142]).

    It would be nice to think that in 2012 a load factor of 90% was going to be achieved, but it seems unlikely as there have been a spate of unplanned shutdowns. The 640MW Torness 2 reactor was mysteriously offline for three months from May 13th to August 10th. (with no explanation). At the same time the 1200 MW Sizewell B nuclear reactor was taken offline. This was Sizewell B’s second unplanned outage in three months. Earlier In February Hinckley Point B was shut down due to a hydraulic leak.Today (Aug 17th) the 550MW Dungeness B22 reactor has been taken offline for refuelling.

    And of course Hunterston B has only been operating at 70% capacity since 2007 as a safety measure.

    I’m not blindly anti-nuclear per se, but I am anti the lies and nuclear hype. Nuclear is expensive and nuclear power stations go wrong. We need a very high load factor to justify the cost of new nuclear, but false claims do not help. If we get 80% from existing plant we will be lucky. I would not trust anything EDF say.

  • Who is ‘the most technically knowledgeable person in Scotland on the truth about wind farms and their worth’ Malcolm?

    Time to name your source if you want to retain any credibility – otherwise you are just trotting out the same tired old figures yet again.

    Your comment about Dr. Mackenzie and the gutter is beyond the pale and I for one feel a public apology is in order. Newsroom?

  • Russell admits vehicle element of former Dunoon ferry was indeed publicly funded
    A threnody is a song, hymn or poem of mourning composed or performed as a memorial to a dead person.

    Quite appropriate. The promise that was the original ForArgyll is indeed quite dead.

    I think I will stick to the Cowal Courier from now on. That’s a proper news site that seems to have your measure.

    Toodle pip!

  • Russell admits vehicle element of former Dunoon ferry was indeed publicly funded
    Oh do cheer up Newsroom! The hybrid ferries are non-military ships being built on the Clyde. Surely something to cheer about?

    Re. your concerns about staff training – I think you will find that staff require retraining whenever a new vessel is brought into service . . . each boat is different.

    And please do stop all this ‘we hear rumours’ rubbish. No-one believes you. Come up with facts and their sources like a real journalist or stop smearing doom and gloom. Less fuel is less fuel. And the new ferries are also designed to have lower maintenance costs.

    Now, here’s some more potential good news on the ship technology front for Scotland . . . CMAL has been commissioned to carry out a feasibility study for Scottish Enterprise to evaluate the technical and commercial possibilities of using hydrogen fuel cells to power zero emission ferries. If this goes ahead it could put Scotland at the forefront of another new technology, with the consequent design, development and manufacturing of hybrid engines being located here. Great news – though I expect ForArgyll will want to talk it down.

  • New Mobile Theme for
    The mobile version isn’t triggered by my iPad, which is a good thing – but it does come up in an iPhone emulator I tried.

    Strangely enough specific mobile versions of websites (as opposed to apps – which are here to stay) may be a relatively short-lived phenomenon. As bandwidth on phones increases dramatically and most displays become HD 1024 pixels wide or more so standard websites become more and more useable. I don’t come across many that don’t display well on the iPad.

    A mobile version was far more essential on older 320 pixel devices like Nokias, but these will die out. The non-mobile version of this site (for example) is quite useable on a new smartphone once it is rotated horizontally.

    Apps that do specific things on mobile devices are another matter – they are definitly here to stay. And for blog sites like this the mobile version definitley increases useability (but see below).

    Some feedback – I couldn’t view the comments on the mobile version, but I was using an emulator rather than an actual smartphone. Can other people view and post comments OK on the new mobile site using an iPhone or Andriod phone?

  • Scottish Conservatives underline common ownership of Saltire
    It is Scottish Labour that really needs to up its game dramatically if it wants to keep a credible presense in Holyrood in the 2016 election. What Ruthie and the Scottish Conservative Party do is of little relevance.

    According to Newsnet Scotland a recent poll shows Westminster voting intentions in Scotland as:

    SNP 39%
    Labour 33%
    Conservative 16%
    LibDem 6%
    Others 7%

    If this doesn’t ring alarm bells for Labour nothing will.
