The Medway Handyman

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.

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 a long term financial investment,
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.

Certainly a long term financial investment, but that does not mean
that there are not reasons to install one in the right
circumstances.
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.
The same can be said of replacing single glazing with
double glazing.
Double glazing cuts down noise - not makes it.
People produce figures to "support" all such claims. However, that
does not mean that the figures are correct.
More correctly, the figures produced to advertise such devices are
*always* a con.

Nowhere will you find anyone with an understanding of sustainability
urging people to rush out and buy a house mounted wind turbine as
the first thing they do. That is just a straw man put up by some.

Some party politicians may urge people to rush out and buy such a
turbine first, but they can defend themselves.
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.

It _may_ be a realistic financial investment - for those off grid, in
windy areas.
Your average house, well, no.
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.

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.

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.

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.

It's probably been too windy...
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.

Debatable. Some, certainly.
While there are undoubtedly people who want to show off, just as
people once did with television aerials, I suspect that the majority
of people who look into such things do so in rather a less shallow
way.
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.

They would then come across government advice on the subject,
such as http://www.sbsa.gov.uk/homeimprovements.html
"If you’re thinking about investing in a wind turbine, a solar panel
or another micro-renewable technology, make sure you’ve limited your
demand for energy first!
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.
"If you have a well insulated home and have reduced your demand for
energy, you may be able to reduce your home’s CO2 emissions if you
add micro-renewables"
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 ?
