Severe solar storms predicted for 2007/8

Severe solar storms predicted for 2007/8
A new computer model suggests that the next solar cycle will be 30 to
50 per cent more intense than the previous one, potentially spawning
magnetic storms that will be more severe and disruptive to
communication systems, reported The Advertiser (8 March 2006, p.35).

Due to start late next year: The next cycle is predicted to
begin in late 2007 or early 2008. Solar storms, which eject plasma and
charged particles into space, can disrupt power lines, radio
transmissions and satellite communication.


No long-term solutions for disposal of waste from nuclear power stations available

admin /8 March, 2006

No long-term solutions for the disposal of nuclear waste, such as the
spent fuel from atomic power stations, were available, let alone
acceptable to the public, Britain’s Sustainable Development Commission
concluded in a report to the Government.

Dangerous, hard to manage and long lasting: The report said
nuclear waste was dangerous, hard to manage, and long-lasting in its
effects, reported Michael Harrison and Michael McCarthy in The Independent Online Edition (Tuesday, 7 March).

Half life of plutonium 24,000 years: For example, the half-life
of plutonium was 24,000 years. The pressure group Friends of the Earth
once produced a poster showing a Roman centurion with the caption: “If
the Romans had had nuclear power, we’d still be guarding their waste.”

Uncertain economics: The waste problem was one of the
Commission’s five key objections to the use of nuclear power stations.
On cost, another objection, the report said the economics of building
new nuclear power stations were highly uncertain.

Little justification for public subsidy: It said there was
little, if any, justification for public subsidy, but if costs
escalated there was a clear risk that the taxpayer would have to pick
up the tab.

Capital costs could swing wildly: The
capital costs of building stations were colossal and could swing wildly
with project overruns and increases in interest rates.

Enormous cost of decommissioning power stations: Another cost
issue was whether to factor in the enormous costs of decommissioning
nuclear power stations at the end of their lives.

US dooms Nuclear Proliferation Treaty by striking deal with India

admin /8 March, 2006

The nuclear non-proliferation treaty (NPT) horse has well and truly
bolted; there’s no prospect of persuading India or Pakistan (or Israel)
to give up their nuclear capabilities after a deal was struck between
the US and India, according to The Australian Financial Review (7/3/2006, p.12).

Washington strikes deal with India: In its current phase the
story runs back to mid-2005, when Washington began negotiations on the
deal clinched during the week, trying to regularise the position of a
nuclear weapon state which, as was its right, ignored the NPT.

France agrees to conditional supply: French President Jacques
Chirac, another would-be nuclear supplier to India and pillar of the
NPT, dodged the issue facing Howard by visiting New Delhi just ahead of
Bush. Chirac did agree in principle to sell India French nuclear
material, including fuels, pending “the adjustment of the international
civil nuclear co-operation framework”. The Bush deal brought this
adjustment closer.

Howard in tricky situation: Howard is in a bind: Alexander
Downer reaffirmed Canberra’s adherence to the NPT only last week. But
Howard wants to broaden Australian access to Indian markets.

US wants civilian nuclear sector: A requirement of the Bush deal
is the creation of a purely civilian nuclear sector which the US can
supply without contributing to India’s strategic arsenal. To comply,
New Delhi will designate eight of its 22 reactors as military.

Thorium still a possibility: Theoretically thorium can be
processed into nuclear fuel and if the process for doing so has yet to
be perfected, India hasn’t given up trying. “We have large thorium
reserves,” said S Banerjee after taking over as director of India’s
prestigious Bhabha Atomic Research Centre in April 2004. “It’s enough
to give energy security to this country,” he said.


Federal Governmen seek answers to potential fuel emergency

admin /6 March, 2006

What would happen if a terrorist attack, full-force hurricane or other
catastrophe suddenly threatened Australia’s petrol supplies? No doubt
the Federal Government would step in and appropriate enough fuel to
guarantee essential and emergency services, argued The Age (4/3/2006, p.8).

Plans to reduce fuel quality: But a current tender from the
Department of Industry Tourism and Resources involved a different
strategy, and that was to reduce the quality of the remaining fuel
supplies – to in effect dilute or adulterate them – to increase the
amount available.

Study undertaken: The department had called tenders from
suitably qualified consultants to complete a study that “examines the
issues associated with decreasing fuel quality as a mechanism for
increasing supply of petroleum products when responding to a liquid
fuel supply emergency”.

Issues to consider: The study would “examine the potential
impact of lower petrol and diesel quality on vehicle operability,
including emission control devices; air quality and other environmental
impacts such as potential impacts to groundwater; industry
competitiveness; and the extent to which net product supply from
refineries, other domestic sources and from imports might be increased
by the relaxation of fuels standards during a national emergency”.

Help farms stay profitable: focus on potential yield, not profit

admin /6 March, 2006

With farmers set to suffer one of the worst cost-price squeezes in 2006
since the early 1990s, farm consultants and advisors have been urged
not to deviate from what should be their core aim: helping farms stay
profitable, reports an article in Farm Weekly (23 February 2006 p18).

Yield important, but farmers have to stay in the game: In too
many cases the focus is not on profit but potential yield, which
according to Australian Association of Agricultural Consultants (WA)
president Paul McKenzie is a red herring. During Crop Updates, Mr
McKenzie first outlined how farmers’ gross margins were worse than
people thought.

Do the sums: He illustrated his argument by providing data on a
farmer selling 2t/ha of wheat at an estimated pool return (EPR) of
$210/t less $10/t for upcountry freight. It was assumed there were no
premiums on dockages. With total variable costs at $200/ha, the
audience was asked to estimate the gross margin, with a choice of
$200/ha, $160/ha and $140/ha.

Margins easily over-estimated: “The correct answer is $140/ha,”
Mr McKenzie said. “There are approximately $30/t costs related to
fobbing and harvest loans to be deducted from EPR indicators.” Mr
McKenzie said the example showed how easy it was for investment returns
to be overstated and risk not to be fully recognised. “Those who chose
$200/ha overstated returns by 43pc,” he said.

SA contributions to new water efficiency strategy aimed to help save Murray

admin /6 March, 2006

A huge new $6 million forest in the Riverland and a rebate for having
rainwater tanks plumbed into homes will be the centrepiece of a new strategy
aimed to help save the Murray, according to The Advertiser (6/3/2006, p.15).

Rainwater tanks to save 18bn litres of water: It has been
estimated 18 billion litres of water could be saved if all SA
households had rainwater tanks plumbed into their homes. From July this
year, all new homes in SA are required by law to have a five-star
energy rating and rainwater tanks.

$400 rebate for rainwater tanks: Premier Mike Rann and
Environment Minister John Hill launched the policy at Unley on 5 March.
Rann said it had been decided to extend the scheme to existing
households by giving them a $400 rebate to have the tanks connected
voluntarily.

$2 million for next 4 years cost: He said $2 million had been
set aside over the next four years to cover the costs. He said the new
Murray forest – the biggest regional forest in the state’s history –
would cover 1600ha and follow the river from Morgan to Renmark.
