1. Following last issue's note on micro-wind power (news215.1), the
Guardian reports on B&Q's new domestic turbines (APPENDIX A).
2. Dermot Finnigan (news215.4 etc.) wrote 28.10.06 to the Queen to ask
that Sir John Parker, NG chairman, be relieved of his knighthood, on the
grounds of his alleged fraudulent misrepresentation of a land boundary
in HM Lands Registry in the course of denying the need for a wayleave.
He has also written to the Prime Minister and keeps writing to the NG
Chairman, apparently without reply.
3. Falkirk Council is to withdraw its objection to the Beauly-Denny
line (APPENDIX B).
4. The Stern Review on the economics of climate change reported this
month. It has been criticised for promoting the case on global warming
made by the IPCC, whereas its brief was on economics and not on
reviewing the science. Stern shows that the economic impact on the world
economy of the sort of climate change suggested by the IPCC would be
severe, but that the (expensive) measures suggested to resist it would
be affordable. However he is not able to say how effective those
measures might be, if at all. One general trend, reflected elsewhere in
government agencies, is towards "adaptation", i.e. preparing to cope
with inevitable climate change, as distinct from prevention. The 27-page
Summary can be seen at
5. Power cuts across Europe caused a stir the evening before bonfire
night (APPENDIX C).
6. The Antarctic ice sheet perhaps isn't melting after all (APPENDIX D),
and sea levels are falling rather than rising, in contrast to the global
warming scare stories unquestioningly perpetuated in the Stern review.
7. My Revolt Chairman's Report 2006 is at APPENDIX E, as accepted at the
AGM.

APPENDIX A B&Q domestic turbines
To see this story with its related links on the Guardian Unlimited site,

Blowing in the wind
B&Q is now selling wind turbines over the counter. But how easy are they
to install? And do they
work? Dominic Murphy gives the lowdown
Dominic Murphy, Thursday October 26 2006, The Guardian
How do they work?
Turbine blades rotate in the wind, turning a copper coil inside a
magnetic field and creating an electrical current, in the same way as a
dynamo. The Department of Trade and Industry estimates that by 2050, 6%
of all our energy could be generated this way, with mini windmills
either attached to the home, or to a mast in the garden. There are two
basic systems: stand-alone or grid-connected. The first has
traditionally been used to power batteries in remote areas. A turbine
connected to the grid will need a "grid tie inverter", which converts
the current to the 240 AC mains voltage.
How much will it cost?
A typical one-kilowatt domestic turbine will cost upwards of £1,500.
With installation, this could rise to £2,500-£3,000. Larger systems in
the region of 1.5kW to 6kW come in at between £4,000 and £18,000. Many
turbines qualify for a government grant of a third of their cost (0800
915 7722; Lowcarbonbuildings.org), and prices are expected to come down
as demand increases: B&Q anticipates selling 50,000 of its Windsave
system, which might explain the price of £1,498, including survey and
installation.
Can you install it yourself?
In theory. However, you will need an electrician to connect it to the
mains, and will not get a grant unless you use an accredited installer.
Will they make a noise?
B&Q says the noise on its turbines is 40 decibels: "This is the
equivalent sound of two people walking in front of your house talking."
A study by Nottingham University found that the StealthGen turbine, the
windmill David Cameron is proposing to put on his London home, is
quieter at 2-3 decibels above background noise.
Do I have to live in a windy area?
Turbines operate best with constant wind, rather than gusting, which can
wear out parts more quickly. Average wind speed in the UK is 5.6m/s,
which is a gentle breeze, and many models are designed to work at around
4m/s. You can check the average wind speed in your area here, but such
measures are notoriously inaccurate, not taking into account local
factors such as surrounding buildings and trees.
How much electricity will it produce?
"Up to 30%" of a household's needs is a common figure bandied about, but
it verges on meaningless because it is often based on average wind
speed. Not only will the true saving depend on how windy your area is,
but how much energy your property uses - according to the Energy Saving
Trust (est.org.uk, 0800 512012), a typical home uses between 4,000kWh
and 7,000kWh per year. So that is two wildly divergent figures from
which to begin your calculations.
Can I sell any surplus electricity back to the national grid?
It is quite possible that you could produce more electricity than you
need at certain times - at night, say, or in a gale. In which case some
turbines will "export" this power back to the grid. In reality, however,
it is actually quite difficult to do. First, you will need to invest in
a special meter (about £120), then negotiate a rate with your
electricity supplier. This will probably be an insulting few pence per
unit of power, as opposed to the 11p or more that they are charging you.
Compare this with Germany, where micro-generation incentives include
paying householders 30p for every unit of solar electricity they export.
Much easier is to sign up with a "green" supplier of electricity such
as Good Energy, which will pay you around 5p for every unit of power you
generate - special meter or not. Then there are ROC (renewable energy
certificate) allowances, which is money you can claim from your
electricity supplier for reducing your carbon emissions (this could be a
round £60 a year, though expect some nightmare paperwork to claim it).
Am I going to get back my investment?
The £1,500 question. Again those average wind speeds figure in some
controversial calculations. B&Q reckons its turbines will take seven to
eight years to pay for themselves at current electricity prices, but a
Sussex University study suggested it could be as much as 28 years for
some models.
Will I need planning permission?
This year's Climate Change and Sustainable Energy Act requires local
authorities to set targets in micro generation, so you could well find a
sympathetic ear at the planning department. However, you will still need
permission and policy varies from council to council. Building Control
will also need to know about your plans.
Do I need a survey?
Nope, but you would be mad not to have one. You can try to find an
"environmental consultant" for some advice, but at the moment the wind
turbine industry is a young, unregulated pup, so you could end up none
the wiser. You can look up the list of accredited models and installers
at
.
Will it structurally damage my house?
A good reason for getting that survey, and a controversial point. Wind
turbines mounted on masts have been around for years and are tried and
tested energy producers. Those bolted to homes are not, and many have
doubts about their suitability. Alternative energy expert Nick Martins,
writing recently in Building for a Future, the green construction
magazine, says: "This is not the same thing as fitting a satellite dish
on the side of a house. I would guess that the lateral thrust exerted by
these turbines on a Victorian chimney stack in a high wind would be more
than sufficient to topple it. The same might be true of the gable ends
of many older houses."
Would I be better off with some other form of micro-generation?
The bottom line is that wind turbines mounted on homes is relatively
untried technology. Solar hot water systems, however, which could cost
as little as £3,000 and qualify for a grant, have been with us for
years. There are no moving parts, so there is less to go wrong, and you
don't need planning permission. Also, achieving 50% of your yearly hot
water needs is not unrealistic. The cheapest power-saving option? More
insulation, switching off appliances and low-energy light bulbs.

APPENDIX B Falkirk Council to drop pylon objection.
Pylon objection set to be dropped
Power line Falkirk Council is expected to withdraw its objection to
controversial plans for a line of huge electricity pylons from the
Highlands
to Central Scotland.
The line, proposed by Scottish and Southern Energy (SSE), would see 600
pylons built on a 137-mile route.
Falkirk officials have recommended that councillors approve the
withdrawal.
The move would mean the authority not taking part in a forthcoming
public
inquiry on the plans, which have attracted thousands of objections.
The authority had earlier lodged a "holding objection" to the plans, but
planning chiefs pointed out that only a small part of the line would
come
into the authority's area, having a minor effect.
A council report added that it had yet to receive additional information
on
an application for a sub-station near the listed Torwood Mire wildlife
site,
meaning councillors would not be able to determine it.
Perth and Kinross, Highland and Stirling councils have objected to the
power
line, but SSE said the development was needed in order to transfer green
energy from proposed projects in the north of Scotland.
The line would run from Beauly near Inverness to Denny near Falkirk,
passing
through the Cairngorm National Park and close to the Wallace monument in
Stirling.
The public inquiry, called by the Scottish Executive, will be held in
2007

APPENDIX C Power cuts strike Western Europe
Last Updated: Sunday, 5 November 2006, 03:01 GMT
Power cuts have struck several countries in Western Europe,
leaving millions of people without electricity.
Power companies said the outage started in Germany with a surge
in demand prompted by cold weather, and then spread to other parts
of Europe.
Some five million people in France lost power, mainly in the east of
the country and including parts of Paris.
"We weren't very far from a European blackout," a senior director
with French power company RTE said.
Pierre Bornard told the French news agency AFP that two German
high-voltage transmission lines failed, causing problems across
western Europe.
This triggered a "house of cards" style system breakdown, he said.
Automatic security systems cut supplies to some customers to avoid
a complete blackout.
Italy, Belgium and Spain were also affected by the power cuts.
Most electricity supplies were restored within two hours of the
outage, and so far no injuries or accidents have been reported.
Fire brigades in France said they had to answer several calls from
people stuck in lifts.
High speed rail links were also disrupted.

Bid to overhaul Europe power grid
Story from BBC NEWS:
Published: 2006/11/05 16:07:20 GMT
Italy's prime minister has said Europe needs a central power authority
to
prevent the kind of blackouts that left swathes of West Europe without
energy.
An overload in Germany's power network triggered outages leaving
millions without
electricity on Saturday night.
Romano Prodi said there was a "contradiction" in having a unified power
network but
no central authority.
Power failed first in Cologne, Germany, before shutting down across
parts of
France, Italy, Spain and Austria.
Belgium, the Netherlands and Croatia were also affected.
"My first impression is that there is a contradiction between having
European
networks but not having a central European authority. It is somewhat
absurd," Mr
Prodi said.
Transmission failure
German utility provider E.ON said early investigations suggested the
supply failures
were caused by overloads in the power network in northwest of the
country,
according to Reuters.
The power outages were quickly restored in most cases but in some of the
worst
incidences:
In Paris, firefighters responded to nearly 40 calls from people stuck in
lifts as the city
lost power
Scores of trains were delayed in Germany's industrial Ruhr region for up
to two
hours
The Italian regions of Piedmont, Liguria and Puglia lost energy
overnight between
2100 and 2200 GMT
In Spain, power was lost in the cities of Madrid, Barcelona, Zaragoza
and parts of the
Andalucia region.
European blackout risk
E.ON said the power failures may have been linked to a line across a
river being
switched off to allow a ship to pass through safely, Reuters reported.
France was one of the worst affected, with five million losing power
mainly in the
east of the country and the capital, Paris, and its suburbs.
"We weren't very far from a European blackout," a senior director with
French power
company RTE said.
Most electricity supplies were restored within two hours of the outage,
and so far no
injuries or accidents have been reported.
The worst recent power blackout struck Italy in 2003, plunging the
country into
darkness for 18 hours between 28 and 29 September.

APPENDIX D ANTARCTIC ICE SHEET MASS BALANCE
CO2 Science Magazine, 8 November 2006
Reference
Wingham, D.J., Shepherd, A., Muir, A. and Marshall, G.J. 2006. Mass
balance of the
Antarctic ice sheet. Philosophical Transactions of the Royal Society A
364:
1627-1635.
What was done
The authors "analyzed 1.2 x 108 European remote sensing satellite
altimeter echoes
to determine the changes in volume of the Antarctic ice sheet from 1992
to 2003."
This survey, in their words, "covers 85% of the East Antarctic ice sheet
and 51% of
the West Antarctic ice sheet," which together comprise "72% of the
grounded ice
sheet.""
What was learned
Wingham et al. report that "overall, the data, corrected for isostatic
rebound, show
the ice sheet growing at 5 ± 1 mm year^-1." To calculate the ice sheet's
change in
mass, however, "requires knowledge of the density at which the volume
changes
have occurred," and when the researchers' best estimates of regional
differences in
this parameter are used, they find that "72% of the Antarctic ice sheet
is gaining 27 ±
29 Gt year^-1, a sink of ocean mass sufficient to lower [authors'
italics] global sea
levels by 0.08 mm year^-1." This net extraction of water from the global
ocean,
according to Wingham et al., occurs because "mass gains from
accumulating sno
w, particularly on the Antarctic Peninsula and within East Antarctica,
exceed the ice
dynamic mass loss from West Antarctica."
What it means
Contrary to all the horror stories one hears about global warming-
induced mass
wastage of the Antarctic ice sheet leading to rising sea levels that
gobble up coastal
lowlands worldwide, the most recent decade of pertinent real-world data
suggest
that forces leading to just the opposite effect are apparently
prevailing, even in the
face of what climate alarmists typically describe as the greatest
warming of the
world in the past two millennia or more.

APPENDIX E Revolt Chairman's Report 2006.
UK energy policy is due to be framed in a new white paper, expected to
promote both renewable and nuclear energy, against volatile oil and gas
markets and the increasing profile of climate change concerns.
On the subject of climate change, the (in)famous "hockey stick" graph
purports to show an underlying trend of a flat temperature profile for a
thousand years followed by a steep rise in modern times. Although that
flies in the face of historical evidence of the mediaeval warm period,
it has been heavily promoted by the IPCC, government agencies and even
the Royal Society. Yet its method is fundamentally flawed, as confirmed
this year by two key US government sponsored reports. Of most interest
to me is the Wegman report by eminent statisticians, which completely
upholds the statistical criticism of the hockey stick. It also confirms
that the flawed method would give such a result when purely random input
temperature data are used. While global warming remains a proper and
serious concern, this falsification of science at the highest level is
equally alarming. Royal Society take note!
Wind power, with its excessive powerline implications, continues to
drive ahead. Wind farms themselves are likely to be the single most
damaging visual impact in the UK over the next decade. Yet the severe
limits to their effect in combating global warming continue to be
misunderstood. Revolt has made representations in the new (limited)
regional and local planning procedures this year. Hambleton DC is at the
forefront of the new processes.
Revolt is collaborating with objectors to the Beauly - Denny 400 kV
proposal in Scotland. A public inquiry is to open in February and is
expected to be a new testing point for considerations of health and
undergrounding. The applicant, Scottish and Southern Eenergy (SSE), had
repeated the old story of a "sterilised swathe" across the countryside
caused by undergrounding, in spite of the contrary example in Yorkshire
(and the photos on Revolt's web site). Yet, after objectors arranged a
presentation to the Scottish Parliament by Europa Cables, SSE has had to
accept that, contrary to its environmental statement, it would use the
more benign XLPE cables rather than the old oil-filled type.
Further developments on new and cheaper forms of undergrounding, led by
European firms, have emerged from objectors in Ireland. Revolt is again
collaborating and gathering information on improved technology.
The stakeholder advisory group (SAGE) on health issues from EMFs has not
yet reported but continues to be very active with Revolt taking a
central part. One outcome is my collaboration with Professor Denis
Henshaw on related research and analysis.
Revolt's web site continues to be heavily used, as we are largely an
internet-based organisation. Over the last year 17 issues of Revolt
email news were circulated.
