By *Ian Angus*
August 24, 2008 -- Will shared resources always be misused and overused?
Is community ownership of land, forests and fisheries a guaranteed road
to ecological disaster? Is privatisation the only way to protect the
environment and end Third World poverty? Most economists and development
planners will answer “yes” — and for proof they will point to the most
influential article ever written on those important questions.
Since its publication in /Science/ in December 1968, “The Tragedy of the
Commons” has been anthologised in at least 111 books, making it one of
the most-reprinted articles ever to appear in any scientific journal. It
is also one of the most quoted: a recent Google search found “about
302,000” results for the phrase “tragedy of the commons”.
For 40 years it has been, in the words of a World Bank discussion paper,
“the dominant paradigm within which social scientists assess natural
resource issues” (Bromley and Cernea 1989: 6). It has been used time and
again to justify stealing indigenous peoples’ lands, privatising health
care and other social services, giving corporations ``tradable permits''
to pollute the air and water, and much more.
Noted anthropologist Dr G.N. Appell (1995) writes that the article “has
been embraced as a sacred text by scholars and professionals in the
practice of designing futures for others and imposing their own economic
and environmental rationality on other social systems of which they have
incomplete understanding and knowledge”.
Like most sacred texts, “The Tragedy of the Commons” is more often cited
than read. As we will see, although its title sounds authoritative and
scientific, it fell far short of science.

"GetUp! is coming... are you?"
This event is planned to start at 5:00 pm on Sep 5, 2008 at Sunshine
Coast, Paradise Dam & Hervey Bay.
http://www.savethemaryriver.com/downloads/pdfs/GetUpSaveTheMaryRiver.pdf.
Some events require registration, so plan ahead. And in the interests
of being climate friendly, there's buses running between the events,
book your seats early!
The proposed Traveston Dam will not only increase Queenslands
greenhouse emissions, but threatens the homes of endangered species
like the Mary River turtle which occur nowhere else in the world! This
is a great chance to get out and meet other GetUp members in your
area, while also taking effective climate action on this important issue.
The more locals in attendance the better our chance of securing
crucial media coverage, so please come along and join in! And do

Dear Friends,
Â
Greetings from MASS & Water Initiatives Orissa !
Â
We are compiling a country strategy paper on "Climate Change and Drinking Water
and Sanitation" that will form the base for a National Workshop on the subject,
we will be holding shortly. For this paper, we are looking for good studies &
reports that narrate impacts of climate change in water and sanitation. We are
also seeking examples of adaptation and mitigation, especially community based
approaches. Please lead us to any reports and web links that you think would
help us get a real picture of these issues in general and India in specific.
Â
May we also request you to kindly share with us your ideas and experiences on
the subject and also please let us know if you think you can participate in the
workshop and contribute a paper. At present we are looking forward to
"Abstracts" of papers that individuals and institutions can present in the
workshop and would shortly write to people with further details on the
workshop. However, it would be highly appreciated if you could share your
ideas and abstracts asap so that we can plan the final list of participants.Â
Selected participants will be provided with travel and logistics by the
organisers.

China has already overtaken the US as the world's "biggest polluter",
a report to be published next month says.
The research suggests the country's greenhouse gas emissions have been
underestimated, and probably passed those of the US in 2006-2007.
The University of California team will report their work in the
Journal of Environment Economics and Management.
They warn that unchecked future growth will dwarf any emissions cuts
made by rich nations under the Kyoto Protocol.
The team admit there is some uncertainty over the date when China may
have become the biggest emitter of CO2, as their analysis is based on
2004 data.
Until now it has been generally believed that the US remains "Polluter
Number One".
Next month's University of California report warns that unless China
radically changes its energy policies, its increases in greenhouse
gases will be several times larger than the cuts in emissions being
made by rich nations under the Kyoto Protocol.
The researchers say their figures are based on provincial-level data
from the Chinese Environmental Protection Agency.
Advertisement
Video showing the extent of China's smog problem
They say analysis of the 30 data points is more informative about
likely future emissions than national figures in wider use because it
allows errors to be tracked more closely.
They believe current computer models substantially underestimate
future emissions growth in China.
We are awaiting a formal comment from the UK Chinese Embassy, but Dr
Max Auffhammer, the lead researcher, said his projections had been
presented widely and no-one had raised a serious complaint.
All those concerned about climate change agree that China's emissions
are a problem - including China itself.
CARBON EMISSIONS
Line graph showing carbon emissions
Global carbon emissions statistics were last published in 2004. They
show Chinese emissions began rising rapidly in 2002.
University of California research suggests China overtook the US as
the worst producer of carbon emissions in 2006
But China and many other developing countries struggling to tackle
poverty are adamant that any negotiated emissions reductions should
not be absolute, but relative to a "business-as-usual" scenario of
projected growth.
That is why this study is of more than academic interest.
If it becomes widely accepted that China's future emissions are likely
to be much higher than previously estimated, that will have to
factored into any future global climate agreement if the Chinese are
to be persuaded to take part.
In brief, although this study looks bad for China's reputation, it may
be good for China's negotiating position.
The Chinese - and the UN - insist that rich countries with high per
capita levels of pollution must cut emissions first, and help poorer
countries to invest in clean technology.
America's per capita emissions are five to six times higher than
China's, even though China has become the top manufacturing economy.
US emissions are still growing too, though much more slowly.
Dr Auffhammer told BBC News that his projections had made an
assumption that the Chinese government's recent aggressive energy
efficiency programme would fail, as the previous one had failed badly.
"Our figures for emissions growth are truly shocking," he said.
"But there is no sense pointing a finger at the Chinese. They are
trying to pull people out of poverty and they clearly need help.
"The only solution is for a massive transfer of technology and wealth
from the West."
He acknowledged that this eventuality was unlikely.
Those scientists aspiring to stabilise global emissions growth before
2020 to prevent what they believe may be irreversible damage to the
climate may be wondering how this can possibly be achieved.

Brendan Nelson's confused call for a renewed debate on nuclear energy
would be funny if it were not so serious, Australian Greens spokesperson
on nuclear issues Senator Scott Ludlam said today.
"The Greens welcome the call for yet another rational, informed debate
on nuclear energy. Australia has these debates every couple of years,
and the pro-nuclear side keep losing. They never seem to figure out
why."
"Australians have a deep distrust of nuclear technology. It is not
because they are emotional, irrational or uninformed, but because
nuclear power and uranium mining have no place in a sustainable society
and people know it," said Senator Ludlam.
"Nuclear weapons, nuclear waste and the risk of accidental contamination
for thousands of years stands in stark contrast to the prosperous,
renewable society that most Australians want. So by all means lets have
the nuclear debate again, and this time let's talk about the role
Australia plays in providing uranium fuel to this most destructive of
industries. I'm eager to hear Minister Peter Garrett's views on that
subject," he concluded.

Wong ducks deforestation hypocrisy-Greens
Tuesday 19 August 2008
The Minister for Climate Change, Penny Wong, has ignored Australia's
logging and burning of native forests as a critical contribution to
global warming in her Sydney speech to loggers today, Australian Greens
Leader Bob Brown said today.
"The latest Australian National University research shows that such
logging may produce up to 25 per cent of Australia's carbon pollution of
the atmosphere. But Minister Wong, while outlining the Rudd government's
overseas aid to stop logging in Indonesia and Papua New Guinea, ducked
Australia's need to stop logging here," Senator Brown said.
"In fact, Prime Minister Rudd has committed $100 million to Tasmanian
transport infrastructure spending with Gunns' proposed pulp mill the
beneficiary.
"Senator Wong's promise to the loggers to fund reforestation activities
is crazy when she backs public funding of a pulp mill which entails
deforestation of 200,000 hectares.
"Senator Wong advocates carbon sinks as "practical action" while also
backing destruction of Australia's biggest carbon sinks - its native
forests. This is bad economic, environmental and forest policy," Senator
Brown said.

S-E NSW biomass power is no solution to climate challenges
19 August 2008
Developing wood-fired power stations based on so-called wastes from
native forestry in NSW's South-East would weaken Australia's ability
to reduce greenhouse gas emissions, according to Greens NSW MP John Kaye.
Dr Kaye who is today visiting the South Coast to talk about energy
issues said: "We will be working hard to stop biomass electricity
generation from native forestry feed-stocks being included in
renewable energy targets.
"Recent research from the ANU massively increased estimates of carbon
locked up in the native forests.
"This moves these biomass power stations from the green side of the
ledger to the brown team. They should should sit alongside coal-fired
generators as major contributors to global warming.
"In a climate change-constrained world, continued wood-chipping of
native forests will inevitably be recognised as an irresponsible and
unnecessary release of greenhouse gases.
"Developing power plants based on biomass from these forests would not
only create new economic dependencies on a high emission activity. It
would actually increase greenhouse gas emissions.
"Professor Mackey's research released two weeks ago shows that ending
the exploitation of Eastern Australia's native forests and allowing
them to regrow would take about 24 per cent of Australia's current
annual greenhouse gas emissions out of the atmosphere for each of the
next 100 years.
"That would be a massive and welcome 136 million tonnes of CO2 annual
contribution to repairing the climate.
"With figures like these there is little hope of generating
sustainable electricity based on products coming from an industry
that is a major emitter.
"Forestry industry propaganda talks about burning wastes to create the
impression of sustainability.
"Wood-chips would inevitably end up in the furnaces and biomass would
drive the continued expansion of an unsustainable industry," Dr Kaye said.

TAMAR VALLEY POWER STATION PURCHASE NOW A FAIT ACCOMPLI?
As Government Energy Strategy Collapses Under Basslink Gamble
Tuesday, 19 August 2008
The Tasmanian Greens today responded to the Premier's Ministerial
Statement regarding the government's buy back of the Tamar Valley Power
Station, which had been predicted by the Greens, saying that the
purchase was now a fait accompli due to Labor control of the Lower
House.
Greens Shadow Energy spokesperson and Member for Bass Kim Booth MP said
today that all domestic power consumers would ultimately pay the price
of both the Tamar Valley Power Station buy-back, and the Basslink
gamble, which has left Tasmania in a perilous energy position, through
increased power prices.
Mr Booth also pointed out that the Premier suddenly has had to take over
the issue of the Tamar Valley power saying that it appears that Mr
Llewellyn had bungled this project and misinformed the public about its
future so badly that Mr Bartlett has had to intervene in a desperate
attempt to restore government credibility.
"The Labor government has now locked Tasmania into expensive power with
no room to move," said Mr Booth.
"This latest farce of the government buying back the Tamar Valley Power
Station is just another sad chapter in Labor's book of energy mistakes."
"Thanks to Labor incompetence and failure to listen to advice, we are
now taking over a half finished lemon with no grid connection at this
time, instead of a unit that should have been custom built to operate
within the frequency restraints of the current Tasmanian system, as the
Greens had advocated when we were the only Party in the Parliament to
vote against the station's sale last year."
"Again and again I queried what was going on with the Tamar Valley Power
Station, and I was just fobbed off by Mr Llewellyn, I broke the news
publicly last week that the government intended to buy back the station
and was ridiculed by the Minister at the time."
"Now it is David Llewellyn who looks ridiculous as his ducking and
weaving, and bungling of the Energy portfolio, has been exposed to the
extent that it has required the Premier to have to step in, confess to
the Tasmanian public, and clean up the mess," Mr Booth said.

Thanks for posting that Peter. Barry Brook's comments on GW/CC
denialism/scepticism, Andrew Bolt's latest fabrications in particular, are IMO
good advice.
As I pointed out (in Qld Greens forums & maybe here as well) the day following
Bolt's appearence on ABC1's Q&A
where he (Bolt) claimed "global warming stopped in 2001". His deception
conflicts with
the fact Europe had its hottest temps on record in 2003, North
America had its in 2007, and 2008 looks like being yet hotter again.
Warm to sceptical science:
http://www.news.com.au/heraldsun/story/0,21985,24085879-5000117,00.html
YOU'VE no doubt
come across a few opinion columns over the past year which claim that
global warming has stopped. Or that we are heading into a new ice age.
Or indeed, that rising carbon dioxide levels have nothing to do with climate
change - it's all just natural causes.
Yet the great majority of news stories on the latest scientific findings say
that global warming is accelerating.
Or that its impacts are happening faster than earlier predicted.
Or that spiralling industrial carbon emissions are pushing us ever faster
towards climate disaster.
Pretty confusing, eh? Who, or what, to believe?
The key to navigating this minefield is to use a bit of sceptical thinking.
By this, I mean "sceptical" in the dictionary sense - doubt what's
told to you at face value, ask sensible questions, consider all
evidence, and most importantly, to demand a consistent argument.
Once you become a real sceptic - something scientists are trained to be - the
rest is fairly easy.
So just as a talking point, let's ask some sceptical questions about
a few of the graphs that the Herald Sun's Andrew Bolt recently claimed should
end the warming hype and make the Rudd Government feel sick.
I don't have space to cover all seven graphs, but you'll get the gist.
Andrew impishly asks: "So, dude, where's my global warming?"
I might as easily respond with the question: "So, mate, what's propping
temperatures up?"
After all, to be consistent, if all those extra greenhouse gases
really don't cause global warming, and if the sun is now in a cool
phase, then why haven't the thermometers immediately dropped back to
the levels of the 19th century?
Why, in 2007, were global temperatures still an average 0.83C higher
than during the first year of modern temperature records, in 1880?
Alternatively, take the much talked about "cool" decade from 1999 to 2008.
If global warming has stopped, why was the most recent decade 0.86C
hotter than the same decade from 100 years before, 1899 to 1908?
Indeed, if 1998 really was the global warming high point, then why
was it an average of 0.33C cooler between 1989 and 1998, but a whopping
0.48C lower the decade before that?
The sun can't be the answer to this problem, since the prevailing
non-greenhouse viewpoint argues that the recent inactive sun (no
sunspots) threatens to take us into the next ice age.
So it must be other natural changes.
Yet they can't agree on what these may be - or find any way to measure their
effect.
The above numbers were taken from the NASA land-ocean surface temperature
record.
But you probably want more than NASA's word for it. No problem.
Last year the World Meteorological Organisation announced that the 11 hottest
years on record have all occurred in the past 13 years.
This finding was based on the UK's Hadley Centre temperature data.
Even Andrew's favoured satellite measurements of the lower
atmosphere show that the hottest decade was 1999 to 2008 and that the
decade before that was cooler, and the decade before cooler still.
Andrew also claims that the seas have stopped rising because of a dip in 2007.
But he left out the standard "inverse barometer" correction - with this the blip
then vanishes.
I could go on, but I've made my basic point.
You can "prove" just about anything by cherry-picking what statistics to show,
and what to leave undisclosed.
But the real issue actually boils down to this: climate scientists don't use
temperature charts to "prove" global warming.
They use the scientific principles of physics, chemistry, geology, biology, and
so on, to form ideas and to make predictions.
Then they go out and test them.
And because scientists are inherently sceptical people, they do this repeatedly.
In as many ways as possible.
It's only those theories and models that have withstood repeated
scrutiny and evaluation against new data that end up making the cut.
It's these results that form the basis of the conclusions of the
Intergovernmental Panel on Climate Change reports. Hard won,
continually verified, science.

global change to government, industry and the community (directly, via
public lectures and workshops and advisory committees, and indirectly
via the media - including television, radio, the print media and
popular science articles).
It is his belief that presenting hard-won technical scientific
evidence to a broad audience in an intelligible way is the surest path
to provoking meaningful societal change towards long-term sustainability.

Renewables target: Government must ignore short-sighted agenda of big
polluters
Brisbane, Monday 18 August 2008 The Rudd Government must ignore the
short-sighted agenda of Australia's big polluters and stick to its
commitment to lift the Mandatory Renewable Energy Target, Australian
Greens climate change spokesperson, Senator Christine Milne, said today.
Senator Milne said, "It is no surprise that Australia's biggest
polluters are lobbying the Government to protect the status quo under
which they can keep raking in the profits and pay nothing for the carbon
pollution they pump into the atmosphere.
"The Australian Industry Group, the Business Council, Cement Australia
and the Aluminium Council are all hard at work in Canberra trying to
lock Australia into a resource economy which will soon be in the past,
and deny us all the benefits of moving swiftly into the clean, clever
future.
"The greenhouse mafia claims that the renewables target will undermine
our export industries, coming on the same day that we are seeing new
concerns that the resource boom is coming to an end, reveal just how
much these people are locked in the past.
"Policies to boost renewable energy are about making sure that Australia
will be in a position to achieve the serious emissions cuts we will need
to make. Without bringing on the alternatives to polluting coal, we face
far higher costs in the future. A high renewables target substantially
reduces the cost of cutting emissions over the medium term.
"With the proposed emissions trading scheme compromised, and early
indications that the scheme's cap will be far too weak, the Mandatory
Renewable Energy Target is the Rudd Government's only remaining scrap of
credibility on climate change. If Rudd and Wong bow to pressure from
polluters on this vital issue, they will pay the political price for
abandoning those Australians who voted for climate action in 2007."
Senator Milne is in Brisbane today in hearings for the Senate Inquiry
into the tax treatment of carbon sink forests. She is available for
interviews on either issue.

COSTLY BELL BAY BUY-BACK PREDICTED
Consumers to Pay for Labor's Energy Bungles
Kim Booth MP
Greens Shadow Energy spokesperson
Monday, 18 August 2008
Contact: State Parliamentary Offices of the Tasmanian Greens, (03) 6233
8300
www.tas.greens.org.au
The Tasmanian Greens said today that the Bartlett government's
confirmation that they intend to buy back the Tamar Valley power station
at Bell Bay from Babcock and Brown, which the Greens had predicted
barely a week ago, has exposed that the state's energy strategy is in
tatters.
Greens Shadow Energy spokesperson Kim Booth MP said that the Labor's
announcement that they would buy back the power station for $100 million
while Aurora would foot the $240 million bill to complete the upgrade,
was an indictment on the lack of coherent strategy and planning by the
government, and also raised further concerns about whether the station
will end up being an expensive 'stranded asset'.
Mr Booth also said that it will be the Mum and Dad electricity consumers
who pay the price for this buy-back through increased electricity bills.
"When I announced last week that the Bartlett government would buy the
Babcock and Brown power station at Bell Bay, it was met with a wall of
spin and denial and yet less than a week later exactly what I had
predicted has been confirmed," Mr Booth said.
"It now appears that the Bartlett government was attempting to keep the
purchase secret in order to dress up a disaster, in terms of a crisis in
the state's energy strategy, as good news."
"The government needs to explain what has changed so quickly to the
extent that a half-finished potential lemon is now worth purchasing,
when only last year the government was adamant that the best option was
to sell this station on the bogus grounds of retiring debt."
"It now appears that Aurora will need to go into debt to complete the
station's upgrade."
"Babcock's power station is a half-finished project, and one which we
suspect cannot connect into the grid."
"The challenge is now on the government to detail how they intend to
connect the station, and how it will put back on track the State's
desperately needed Energy strategy," Mr Booth said.
Mr Booth reminded that the Greens were the only Party to vote against
the sale of the Bell Bay power station, and had the government not sold
it the design of the generators would have been to suit the Tasmanian
electricity grid frequency controlled requirements but instead Labor is
now purchasing by knee-jerk reaction equipment that was purchased to
suit the needs of Babcock and Brown and which may not be able to be
connected to the grid, or if so, at a vastly reduced capacity.

Come Clean on Port Stanvac Clean Up
The Rann Government has refused to release, under Freedom of
Information, progress reports on the clean up of the Port Stanvac oil
refinery site.
"The Government is refusing to tell us what progress is being made by
ExxonMobil at Port Stanvac. What dirty secrets are they hiding? This
has a real smell about it," said Mr Parnell.
"The public has every right to be suspicious - especially as the
Government has announced Port Stanvac as the preferred site for their
desal plant before finalising negotiations with ExxonMobil.
"They have put themselves in a very tricky bargaining position.
ExxonMobil's responsibility to clean up Port Stanvac must not be
traded off by the Government in order to secure favourable terms for
the site," he said.
Under the agreement between the Government and ExxonMobil signed in
July 2006, the company was required to provide a progress report every
six months to an Independent Site Environmental Auditor and the
Environmental Protection Authority (EPA).
The Department of Premier and Cabinet has refused to release to Greens
MLC Mark Parnell the three reports completed so far on the grounds
that it 'could have an adverse effect on the business affairs of the
third party'.
"Why won't they release a report they were publicly heralding just two
years ago?
"Is the pollution worse than we thought, or has the company made
little or no progress on their clean up?
"Either way, the public has a right to know, especially if a third of
Adelaide's water is set to be manufactured on this land," he said.

SLIVER Technology:
SLIVER solar cells are a new type of solar cell with the potential to
revolutionise the global solar power industry. They were developed at
the Centre for Sustainable Energy Systems with funding assistance from
Origin Energy. SLIVER technology uses a revolutionary process to
achieve high efficiencies while significantly reducing the amount of
expensive silicon in solar cells. Solar modules made from SLIVERs can
be lightweight, flexible and transparent and offer imaginative
opportunities for building integration and other applications. By
substantially improving the cost competitiveness of photovoltaics
compared to electricity derived from fossil fuels, slivers have the
potential to revolutionise the photovoltaics industry and
simultaneously address the critical environmental issue of global warming.
A solar panel using SLIVER Cell technology needs the equivalent of two
silicon wafers to convert sunlight to 140 watts of power. By
comparison, a conventional solar panel needs about 60 silicon wafers
to achieve this performance. By dramatically reducing the amount of
expensive pure silicon, the largest cost in solar panels today, this
new technology represents a major advance in solar power technology.
The above is an excerpt from:
http://solar.anu.edu.au/research/sliver.php
Two communities affected by one new global market – the trade in carbon
dioxide. In Scotland, a town has been polluted by oil and chemical
companies since the 1940s. In Brazil, local people's water and land is
being swallowed up by destructive monoculture eucalyptus tree
plantations. Both communities now share a new threat.
As part of the deal to reduce greenhouse gases that cause dangerous
climate change, major polluters can now buy carbon credits that allow
them to pay someone else to reduce emissions instead of cutting their
own pollution. What this means for those living next to the oil industry
in Scotland is the continuation of pollution caused by their toxic
neighbours. Meanwhile in Brazil, the schemes that generate carbon
credits give an injection of cash for more planting of the damaging
eucalyptus plantations.

Your chance to support Christine Milne's FIT Bill
Posted by: "Steve Meacher" via Climate Emergency Network
Date: Wed Aug 13, 2008 1:19 am
This Friday, August 15, is the deadline for submissions to the
SenateInquiry into Christine Milne's Private Member's Bill for a
nationalgross Feed-in Tariff for all renewable energy technologies.
http://greensblog.org/2008/06/20/help-me-make-a-renewable-feed-in-law-
a-reality/
http://www.aph.gov.au/Senate/committee/eca_ctte/renewable_energy/

It is extremely important that the Inquiry receives a large number of
submissions from interested parties in order to demonstrate to the
members of the Committee that there is strong demand for a feed-in.

The Great PV Solar Rip-off
Greens MLC Mark Parnell has asked the Essential Services Commission to
investigate how much electricity companies are paying householders for
the electricity they produce from their solar panels, after accusing
retailers of using the introduction of the solar feed-in premium laws to
make a windfall profit at taxpayer's expense.
Solar panel owners should be receiving 2 payments:
1. A payment for the electricity the households export to the grid
(paid for by the energy retailer)
2. A 44c/kilo watt hour premium (paid for by all domestic
electricity consumers)
Instead, some retailers, including Origin and AGL, stopped paying the
first amount when the feed-in scheme commenced on July 1 this year.
This will potentially deliver a windfall profit of about $350,000 (and
possibly much higher) to big energy companies - money that should be
going to households as an incentive to encourage more people to install
solar panels, not as a subsidy to big energy retailers.
"The feed-in incentive should be on top of, not replace, what the
electricity retailers were already paying. Otherwise, South Australian
electricity consumers are effectively paying almost half of the feed-in
law benefit directly to the big end of town, not to the householder with
the panels," said Mr Parnell.
"Electricity retailers were quite happy before July 1 to pay for the
power generated from household solar cells. Now, some electricity
retailers are using the feed-in laws as an excuse for the rest of the
community to pick up the tab.
"Retailers have to pay for the electricity they source from power
stations, why shouldn't they pay for the electricity produced from
people's roofs? They used to pay; now they don't pay a cent. That's
just not fair.
"They are collecting windfall profits while handballing responsibility
for climate change action to the rest of the community. If companies
like Origin and AGL don't start doing the right thing, I will introduce
legislation to fix up the scheme," Mr Parnell said.

regarding Victoria's Feed-inTariff LegislationImportance: High Dear
David, On behalf of Helen Halliday and Bob Weis, thank you for
meeting with us lastweek. We appreciate your having been so generous
with your time andattention. Please find attached an electronic
copy of the briefing notes left with you- We trust this document will
also be of interest to your colleagues. As agreed, climate change
is happening much faster than even the worst casescenarios predicted
by IPCC scientists. Further evidence emerges daily thatour climate is
approaching dangerous tipping points - such as the polar icevanishing
100 years ahead of
schedulehttp://www.guardian.co.uk/environment/2008/aug/10/climatechang
e.arctic. Of course we know that by driving our environment to
collapse we willdecimate our economy. Business as usual is simply not
an option. Victoria must move rapidly towards a zero emission
economy and, while itwill be a massive transition, it is doable, it
will be affordable and itmust be done. Removing all subsidies for
fossil fuel energy sources and projects, whileputting a high price on
pollution will generate many new opportunities. Asexperience in
Europe has demonstrated, renewable energy and energyefficiency
industries offer more secure and more sustainable jobs. For
amultitude of reasons, it would be foolish and irresponsible for us
tocontinue to protect the OLD at the expense of the NEW local
economy. Meanwhile, the Brumby Government continues to commit
billions of tax payer'sdollars to projects which will have disastrous
environmental impacts onVictoria. It is of deep concern to us that
the Opposition is literally'Missing in Action' while these appalling
decisions are being made. While wehave no effective Opposition, our
democracy is severely compromised. For example, in our view, there
has not been a meaningful response from yourParty to: . The
legislation for a Victorian Feed-in Tariff - a distortion ofthe
market mechanism adopted by over 40 nations so far and designed to
fail(see attached doc) . the Wonthaggi desalination plant proposal -
already being dubbedthe worst infrastructure bet ever taken by a
first world
government<http://www.climateemergencynetwork.org/images/stories/cen/d
esal.doc> Properprocess would reveal the deception in desal .
Proposals to build more road tunnels instead of improving
publictransport . Approving and funding the HRL Limited coal-fired
electricity plant . Dredging the bay at massive financial and
environmental cost forno apparent social or economic gain .
Continuing to allow logging of Victoria's old growth

Government appears to be both out of touch and out of control. In
search of answers as to why efforts to implement sustainability
measurescontinually meet a thick brick wall with decision makers, and
having spokenwith a number of other campaigners also meeting with
VictorianParliamentarians, we are convinced that Peter Batchelor is
the seniorMinister most responsible for frustrating progress. This is
the same PeterBatchelor whose involvement in fraudulent 'how to vote'
cards was covered upby the Cain Government in the mid 1980s. Perhaps
it is time for MinisterBatchelor to wake up to the reality of 21st
Century life or re-think hisposition entirely. Perhaps, in the
interests of the wider community, heneeds some help with this
decision. Finally, with regards to the climate emergency we face,
here are someshort-cuts to the important messages in the new book
Climate Code Red byco-authors Philip Sutton, The Arctic Challenge for
Australia,on ABC RadioNational Perspective last Tues
05/08/08<http://www.abc.net.au/rn/perspective/>http://www.abc.net.au/r
n/perspective/ and David Spratt's recent article ispasted below.
Perhaps the two most outstanding books on global warming to have
beenpublished lately are The Hot Topic .. and Climate Code Red. Were
I a philanthropist, I would purchase several hundred copies of
bothand send them to our politicians and policy-makers. Robert Manne
(The Monthly) David, we were encouraged by your commitment to seek
cooperation fromJennings to bring the Feed-in Tariff legislation to
the next COAG meetingand will be in touch regarding any further
developments. After all, the VicFiT presents the ideal opportunity
for all Victorian Parliamentarians to'walk their talk' re
sustainability. Thank you again for your time and attention -

cubic meter, r = radius of the wind turbine in meters, and v = velocity
of the air in meters per second.[5]
As the wind turbine extracts energy from the air flow, the air is slowed
down, which causes it to spread out. Albert Betz
<http://en.wikipedia.org/wiki/Albert_Betz> , a German physicist,
determined in 1919 (see Betz' law
<http://en.wikipedia.org/wiki/Betz%27_law> ) that a wind turbine can
extract at most 59% of the energy that would otherwise flow through the
turbine's cross section, that is á can never be higher than 0.59 in
the above equation. The Betz limit applies regardless of the design of
the turbine.
This equation shows the effects of the mass rate of flow of air
traveling through the turbine, and the energy of each unit mass of air
flow caused by its velocity. As an example, on a cool 15 °C (59
°F) day at sea level, air density is 1.225 kilograms per cubic metre.
An 8 m/s (28.8 km/h or 18 mi/h) breeze blowing through a 100 meter
diameter rotor would move almost 77,000 kilograms of air per second
through the swept area. The total power of the example breeze through a
100 meter diameter rotor would be about 2.5 megawatts. Betz' law states
that no more than 1.5 megawatts could be extracted.

Hello again Ghoppy9,
Have my precautionary comments deterred you from your fledgling
interest in whirlyig power?
You were thinking of using a whirlygig to generate some household
power and I raised some potential difficulties with the concept -
although I know you'd definitely get SOME power from such a device.
I found this on the Net at ..

"The most ubiquitous application of the Savonius wind turbine is the
Flettner Ventilator which is commonly seen on the roofs of vans and
buses and is used as a cooling device. The ventilator was developed
by the German aircraft engineer Anton Flettner in the 1920s. It uses
the Savonius wind turbine to drive an extractor fan. The vents are
still manufactured in the UK by Flettner Ventilator Limited."
.. and also this:
"Description:
Savonius wind turbines are a type of vertical-axis wind turbine
(VAWT) used for converting the power of the wind into torque on a
rotating shaft. They were invented by the Finnish engineer Sigurd J
Savonius in 1922. Savonius turbines are one of the simplest turbines.
Aerodynamically, they are drag-type devices, consisting of two or
three scoops. Looking down on the rotor from above, a two-scoop
machine would look like an "S" shape in cross section. Because of the
curvature, the scoops experience less drag when moving against the
wind than when moving with the wind. The differential drag causes the
Savonius turbine to spin.
"Because they are drag-type devices, Savonius turbines extract much
less of the wind's power than other similarly-sized lift-type
turbines."
So ghoppy9, to spare you much experimental effort (which was my noble
aim in order to forestall teeth-grinding frustrations, vexations and
miscellaneous sufferings!) I suggest you search the Net for "Vertical
wind turbines" or have a go at designing something uniquely your own.
I wish you the best of success in such efforts.
There's also wind turbines on You Tube.
