B & Q Wind Turbine

Discussion in 'UK DIY' started by The Medway Handyman, Jan 20, 2007.

  1. About a month ago I spotted one of these being fitted to a house just around
    the corner.

    Guys fitting it had a brand new van, brand new access tower, brand new hi
    vis clothing. Looked like they had just equipped themselves from scratch.

    Same guys came back last week & removed it.

    I wonder if it's because they are having problems with them? I keep hoping
    to spot the house owner so I can ask.

  2. The Medway Handyman pretended :
    Not worth the investment, if you were considering one, nor are they
    green if you do the sums.

    The house occupants were too old for that sort of vibrator.

    Certainly not a long term financial investment. If you google for
    figures from the people that have recorded their total output, you'll
    see theyre more total loss than investment. If anyone were getting
    payback then their good figures would get published as well.

    If you do the sums regarding windspeeds in populated areas, again same
    deal. These things are a sad misapplication of technology that makes a
    workable fringe technology look terrible.

    Wrong sort of wind...

  6. I'm willing to bet spending the same money on near any house on extra
    insulation would conserve more energy than one of those will generate.
    Double glazing cuts down noise - not makes it.
    More correctly, the figures produced to advertise such devices are
    *always* a con.

    People produce figures to "support" claims that "wind turbines" are green.
    However, that does not mean that the figures are correct.

  8. It would be interesting to know the (environmental) cost of producing
    these windmills...

    £5 in Shanghai and a contribution to this week's coal fired power station.

    That's the problem, their site surveys say great, lets sell you one,
    even when payback for 99% of the population is never going to occur.
    Its the package thats bad rather than windgen technology, unfortunately
    the public will interpret it that windgens are no good.

    If you strap in on your car and drive up and down the street outside at
    60 mph it works great - you need a long extention lead though.

  12. But that's the way the majority perceive it. Doing something 'active'
    rather than passive like insulation. Something to show - and show your
    neighbours - for the money.
    No political party has even scratched the surface with ideas about saving
    energy.

    The obvious thing would be for each B&Q store to have one installed,
    coupled to an in-store display showing real-time and historic output
    data.

  14. This is very true. The hark on about loft insulation, HW tank insulation,
    double glazing, LE lamps, and make some paltary grants available if you
    qualify (generally meaning you have to be on state benefit of one form).

    If they where really serious they would ensure that every house was
    *properly* insulated and draft proofed with correct attention paid to
    ventilation. But loft insulation isn't sexy and doesn't show, you don't
    get many votes from it.

  15. submitted this idea :
    These types of stores are usually built where there is a great deal of
    open space or at least large car parks, such that the wind would be
    less turbulent than it would be if installed at a typical semi. Air
    turbulence makes a big difference to the efficiency of a windmill and
    none of this seems to have been taken into account.

    Therefore it would not be a fair comparison of likely output once
    installed at a B&Q customers site.

  16. Quite likley. I spotted a small, very much B&Q like, turbine on a house
    near us this morning. I've not seen it before so I fairly sure it is very
    new. Now this house is just above the 440m (1440') contour and directly
    exposed pretty much all the way from South to North via West. Superb open
    views across the South Tyne valley just like us.

    This morning at the time I drove past (0745) my anemometer (at 1400') was
    giving a mean speed of F6 Strong Breeze 25mph NW'ly gusting to the mid
    30's mph. This turbine was hardly rotating. Now I don't know what the
    design RPM is for these things in that sort of wind but I should imagine
    it's a little more than the 20 or 30 RPM (2 sec or more per revolution)
    that this one was doing. It looked to me as if it was being braked, I
    don't think the blades were feathered.

    I half know the people who live there I shall have to enquire... Note
    that this house is probably in a pretty ideal location, so if it isn't
    making a decent amount of power most of the time a similar turbine
    elsewhere just isn't going to do anything useful, at least as far as
    energy generation is concerned.

    For us F0 to the start of F6 Strong Breeze (25mph+ sustained) is not
    windy at all. F6 is a "little windy" but nothing out of the ordinary.
    "Windy" is F7 Near Gale (32mph+ sustained), in winter any decent Atlantic
    depression will produce winds to that level (5 in Nov, 9 in Dec, 4 in Jan
    so far...). "Very windy" is F8 Severe Gale (42mph+ sustained), just 4 in
    the last couple of months. Gust speeds are generally 10mph above the
    sustained speed with the odd half dozen/hour 15 to 20mph above the
    sustained speed. Vistors nearly always comment on the wind and unless it
    really is blowing a Gale our reponse is normally "What wind?"...

    Fair point, but it would at least show whether the things worked at
    all. Perhaps the manufacturers should enter into a deal with some
    domestic customers, supplying and fitting instrumented turbines in
    typical locations at reduced price. In return they would be supplied
    with output data.

  18. You have a rather more charitable view of folk than me. The very fact that
    B&Q sell them will give many the idea they will work in the area that
    store serves. After all twerps like drivel set great store on who sells
    electronic scale 'preventers'. Argos - at one time at least - wanted your
    postcode before selling you a FreeView tuner, since they won't yet work
    anywhere. Yet it's easy to find out which areas are covered. I'm sure you
    can think of other examples.

    If that's the real quote it's poor English. 'Energy' is missing between
    'renewable' and 'technology'. Although it's a Freudian slip - things like
    wind generators on the vast majority of domestic premises *will* need
    renewing long before they've paid the initial investment.
    At least that bit *may* be correct. The jury is out on whether it reduces
    overall CO2 emissions rather than just at the point of use.

    Why would any company do something that would
    a) cost them money
    b) wipe out 99% of sales ?

    Maybe they'd put it on the wrong house.
