B & Q wind turbines ?

    What a bloody laugh.

    Just been doing a few calculations on those bloody B & Q wind turbine
    things, I reckon that by the time they have paid for themselves, the
    bearings will have gone and the unit will be shafted.
    So for all your troubles you will end up with a free scrap wind
    turbine, which ironically will have created roughly the same amount of
    carbon emissions in its production and subsequent disposal, as it saves
    by coming into existence.
    Its enough to make you want to roll about on the bloody floor laughing,
    you may as well get one of those kiddies windmills from the seaside and
    stick it on your roof, the effect on your wallet will be pretty much
    the same.

    I hate these wind turbines with all my heart. How they can be called
    environmentally friendly I do not know. The are a blot on the landscape
    and noisy. Also the amount of power they generate is pathetic, only
    those in Scotland get anywhere near the 30% the government forecast, and
    the loss to transfer the power wipes that advantage out.

    LOL! While you're busy hating those you'll not be wasting your energies
    hating other things :)

    I seem to remember reading somewhere that small turbines such as this can be
    efficient if they're used to heat water (domestic hot water or for heating).
    You can then use a simple immersion heater type arrangement which has little
    of the eletronic jiggery-pockery required to sync. them to the mains
    (seperate immersion element of course). I believe it's the electronics that
    are wasteful for such "local" turbines.

    Of course transmission loss from the big boys is a problem but it is from
    all generators. The best location for a powerstation is "at the end of your
    road" - but NIMBY immediately cuts on.

    Better yet for gas generation is local combined heating and power systems.

    Its the initial cost thats the biggest problem, making payback time way
    into its service life, if they were £50 the story would be different.

    I think they look rather nice, and having camped and walked near them
    I've never noticed them being much noisier than the wind that's powering
    them when up close - further away they're inaudible.

    I agree wholeheartedly, for the large ones. I thought the OP was talking
    about the small, 'domestic' sized ones. I've never seen one in action. A
    supplier told us that our situation wasn't suitable, too much turbulence
    from other buildings and trees.

    I'm thinking about marketing ones with empty shells and no control gear at a
    much lower cost. I think they will sell well to those who want something to
    point to when people criticise their big 4X4s. Maybe I will add electric
    motors so they turn and still fulfil their role when the wind isn't blowing.
    They will sell well to politicians as well I expect.

  9. We are talking about small doemestic jobbies not commercial ones. These
    small ones are noisy.
    Doesn't mean they are not noisy but that is a different and very poorly
    researched area.

    Surely it's a complete nonsense to use a turbine to generate electricity
    and then use it all to heat water? Why not just convert the mechanical
    power to thermal energy by a paddle in a tank?

    Because that doesn't involve enough "technology" so isn't considered
    marketable.

    If you do that, Mr Hansen will demand that the electric motors are solar
    powered..

    The pump on our solar hot water panel is solar powered. Excellent idea.

    Proof that green supporters have no sense of humour?

  16. I went to a comedy club a while ago and one of the acts did a bit on wind
    farms.

    He reckoned he had discovered where the wind comes from - he had seen these
    great big fans in Cornwall that made it. He knew it was true because the
    faster they ran the windier it got! He also said he wouldn't like to pay
    the electric bill to run them :)

    What a terribly sad reflection it would be on a country whose mechanical
    engineering products powered the world, and which produced accurate
    clocks 350 years ago (that are still running today), and built Merlin
    and Napier Deltic engines, if we couldn't turn a shaft through a couple
    of right angles and swish a paddle in a tank. Have we really got so
    obsessed with "solve it in the software" that this seems too difficult
    to contemplate? Cost? I can buy a mechanical watch movement, with auto
    winding, and in one-off quantities, for 5 quid, so there is still the
    capacity for low-cost manufacture out there.

  19. I'll bet it's not made in the UK, though.

    No - proof that you don't reecognise it :)
