Considering thorium
Julian Cribb sings the praises of thorium reactors as having a lot of passive safety, as well as other attractive features (including scalability in size, and no need for large amounts of cooling water.)
I must admit, I have read little about them, and thought that, to a large extent, they were still pretty experimental.
I guess it's time to correct my knowledge deficiencies.
It's complicated, Part 2
....researchers at Columbia University's School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation of the Southern Hemisphere all the way to the equator. While previous work has shown that the ozone hole is changing the atmospheric flow in the high latitudes, the Columbia Engineering paper, "Impact of Polar Ozone Depletion on Subtropical Precipitation," demonstrates that the ozone hole is able to influence the tropical circulation and increase rainfall at low latitudes in the Southern Hemisphere. This is the first time that ozone depletion, an upper atmospheric phenomenon confined to the polar regions, has been linked to climate change from the Pole to the equator.As the BBC version of the story notes:
The team found that overall, the ozone hole has resulted in rainfall moving south along with the winds.
But there are regional differences, particularly concerning Australia.
"In terms of the average for that zone, [the ozone hole drives] about a 10% change - but for Australia, it's about 35%," Dr Kang told BBC News.
The CSIRO will no doubt be very interested in the study.
It's complicated
Despite the emergence of regional climate policies, growth in global CO2 emissions has remained strong. From 1990 to 2008 CO2 emissions in developed countries (defined as countries with emission-reduction commitments in the Kyoto Protocol, Annex B) have stabilized, but emissions in developing countries (non-Annex B) have doubled. Some studies suggest that the stabilization of emissions in developed countries was partially because of growing imports from developing countries. To quantify the growth in emission transfers via international trade, we developed a trade-linked global database for CO2 emissions covering 113 countries and 57 economic sectors from 1990 to 2008. We find that the emissions from the production of traded goods and services have increased from 4.3 Gt CO2 in 1990 (20% of global emissions) to 7.8 Gt CO2 in 2008 (26%). Most developed countries have increased their consumption-based emissions faster than their territorial emissions, and non–energy-intensive manufacturing had a key role in the emission transfers. The net emission transfers via international trade from developing to developed countries increased from 0.4 Gt CO2 in 1990 to 1.6 Gt CO2 in 2008, which exceeds the Kyoto Protocol emission reductions. Our results indicate that international trade is a significant factor in explaining the change in emissions in many countries, from both a production and consumption perspective. We suggest that countries monitor emission transfers via international trade, in addition to territorial emissions, to ensure progress toward stabilization of global greenhouse gas emissions.Here's my half stupid suggestion: can we agree that Apple products are as good as they need to be for the next 20 years? In fact, now that I think of it, all computers are as good as they need be for the next ten to 20 years.
I'm pretty happy with TV technology as it is too. Does anyone need a better audio system than those available at the moment?
If you stop making things brighter and shinier, maybe people will stop buying new ones. Then China can shut down several factories in a few years time, people in the West won't buy so much stuff, and we can all feel better about importing less CO2.
Just call me Clive 2.

Couple of videos about ocean acidification
The first makes me feel cold just watching it. Mind you, I am not sure of the significance of the phytoplankton polymer production that he is researching, but still it's interesting to see the efforts scientists go to:
The next is about ocean acidification generally, and the effect on larvae of some shellfish in particular. Seems a sensible man:
Back on board–kinda
So, what did I miss while touring Australia’s South Island (a.k.a. Tasmania. Photo post to come.)
Labor in more than a spot of bother with refugees; Labor and Gillard’s popularity still down. Ho hum: there is obviously not going to be any change for Labor until they have some sort of circuit breakers of success; we all know the government is going to look ineffectual until something starts to appear to be a decent policy well implemented. Could Gillard be the opposite of Rudd: too reliant on her Ministers working out the details when the country really wants to know what they are? Time will tell, I guess.
The PM’s de facto having a chat with the Empress of Japan: I bet he never saw this future role for himself 5 years ago. I do wish they would marry – Tim and Julia, I mean, not Tim and the Empress. While some would bemoan this as a cynical move to reverse the popularity slide, all conservatives should rightly welcome it as a good example for the institution of marriage, and visited Asian royalty and leaders would no doubt be much relieved. But while ever they continue to do things like attend a royal wedding, they keep inadvertently bolstering the image of opportunism if they were to marry soon afterwards. Who cares – just do it, I say.
Andrew Bolt still banging on about Fukushima not being such a bad thing because no one has (yet) died of radiation. Meanwhile, in Japan, where the 80,000 odd people who had to leave the 20 km evacuation zone have been given 5 hours to collect stuff from home before the enforced exclusion from the zone, and people in the band of higher contamination to the north west well outside of the evacuation zone have been told to leave their towns within the month, they might feel somewhat less sanguine about nuclear power.
(OK, let’s assume the Japanese government is being overly cautious. Yet they are acting on scientific advice, and hey, would Andrew Bolt or Gavin Atkins move back into the area with his own children if that was the advice being given? Look – Atkins is right to bemoan anti nuclear drama students that even want to shut down the small, medical isotope providing facility at Lucas Heights; but fair’s fair. Stop acting as if the indefinite abandonment of huge swathes of land and townships – a 20 km radius is a lot of area, and there are towns 30 or more km away about to be largely abandoned too – is just worth a shrug of the shoulders. Your much proclaimed low number of radiation deaths comes at a very, very high human and economic price – in both Chernobyl and now Fukushima.)
As for other areas of the world which might have some major human issues if there is a nuclear accident – Nature ran an interesting article pointing out that many plants are much closer to large population areas:
Yet working out the risk position of such areas is complicated, as the rest of the article argues. Well worth a read. I would say it largely supports my hunch: smaller nuclear is better; passive safety should now be the over-riding feature of future design. (And keep them away from large population centres anyway.)An analysis carried out by Nature and Columbia University, New York, shows that two-thirds of the world's 211 power plants have more people living within a 30-kilometre radius than the 172,000 people living within 30 kilometres of the Fukushima Daiichi plant, who have been forced or advised to leave. Some 21 plants have populations larger than 1 million within that radius, and six have populations larger than 3 million.
Speaking of Andrew Bolt – remember him pooh-poohing the European flight bans last years during the Icelandic volcanic eruptions? Because computer modelling was used to try to track the ash? (As someone else already noted, this was a ridiculous comparison of climate models with computer forecasts for a few day’s of wind; but Andrew is very opportunistic with his anti-modelling line.) Well, a couple of scientists have published a paper begging to differ. The ash stayed dangerous for a long time. (And I am betting there was no easy way to track its precise path in the sky.)
It seems it doesn’t matter what safety issue it is – radiation, volcano ash, climate change – the right of politics has taken such an ideological position against AGW that it distorts their attitude to all other issues of public safety too.
Conservative politics hasn’t always been like this – they used to like and trust science, I think. One day it will swing back that way, but it seems a long, long way off in the future.

Good points, Tim
Tim Costello makes many good, sensible points on the issue of regulation of poker machines.
Polling today indicates quite strong support from the public for tightening their regulation. Support seems stronger from lower income people. So much for one argument from one participant at the blog noted next that regulating pokies was a form of class warfare to punish the working class for enjoying their preferred form of gambling.
Libertarian types at that certain blog continue to show themselves as whiny, hysterical types who exaggerate and use straw man arguments to disavow any government proposal to tighten regulation in virtually any field, no matter what evidence is provided. In fact, their ideological blinkers means that most of them don't need to consider evidence at all - just look at the typical libertarian attitude to climate change.
Libertarians are the mirror image of left wing ideologues who put their ideology ahead of what comprises good government from the view of common sense pragmatism. Both are to be avoided.

Not built like they used to be?
Is it just me, or does it seem to anyone else that Navy ships just don't seem to used for very long anymore before they're decommissioned and then, nearly as a matter of routine, sunk for an artificial reef? It just seems to happen so often now, and for ships I have a vague recollection of hearing about when they were in service; seemingly not so long ago.
Or is this just a sign of my advancing decrepitude?
Yuri's ghost
The Guardian has a brief piece on the superstitions of astronauts, particularly Russian ones relating to Yuri Gagarin:
They leave a red carnation at his memorial wall, visit his old office and ask permission from his ghost before launch. More bizarre is the tradition of male cosmonauts urinating on the right rear wheel of the bus used to transfer them to the launch site (women have the option of dashing a cup of their own urine on the wheel too).Well, I suppose that rules out men with a "shy bladder" ever being an astronaut in Russia, then.
Here's the link to an story with a lot more detail of such superstitions, and it's a fun read.
Where's the Beano?
Anyway, I was the one who chose the cassoulet (the hearty bean dish with sausage, duck and pork belly in it), bravely knowing the likely later consequences, which did in fact arrive, but not until about 4 am.
Which got me thinking: whatever happened to Beano. I remember reading about this in Discover magazine in (I think) the 1980's. They used to have a humourous columnist, a woman whose name I forget now, but I remember her column about a forthcoming enzyme based product which (if I recall correctly) was to be sprayed on your beans to reduce later gaseous consequences.
But Beano has never appeared in Australia, and I have never gone looking for it on the internet.
And here it is: you can get it in the US, but to take as a tablet, not put on your bean-y meal. (That was probably never a goer, but I'm sure I remember that being suggested as the way it would be used.)
I am pleased to see that the anti-flatulence product does not take itself too seriously. The videos at the University of Gas are done with an appropriate level of humour.
Maybe you can buy it online in Australia, but I have never noticed it in a pharmacy or supermarket. If it works, this is a product that deserves better marketing here.

Understood up to a point...
I always start to eventually get lost in the detail when reading about Bell inequality, free will and determinism, but this story about it was not a bad explanation for the most part.
They only want you to think they did
We all know they actually ended up in cardboard boxes in Mulder's basement office. How naive do they think we are?
Living in a hole
People a bit smarter than expected?
From the link:
A major tobacco-industry funded advertising blitz has backfired, with new research revealing the “It won’t work, so why do it” campaign persuaded more people to support the plain packaging of cigarettes than oppose it. The Cancer Council Victoria survey of 2,101 Victorians who recalled the ad campaign found has found that more than eight out of ten (86.2%) respondents said the ad didn’t affect their view of plain packaging 8.4% of respondents said the ad actually increased their support of plain packaging.Neat.
Nice view!
Just click on the link to see a lovely pic of the great view they have in the International Space Station from its big-windowed cupola.

Picturing C
"I just burnt a Koran...in my bedroom."

"Welcome all. So, our policy response to the last 4 Labor initiatives: bullsh*t, bullsh*t, bullsh*t and double bullsh*t. Meeting adjourned. Now to relax with some freedom sticks."
"My gym has a very loose dress code..."

"I moisturise daily, but I don't think anyone notices."

Atlas burned
Here's his mea culpa paragraph:
Millions of people have read “Atlas Shrugged” and been brought around to common sense, never mind that the author and her characters don’t exhibit much of it. Ayn Rand, perhaps better than anyone in the 20th century, understood that the individual self-seeking we call an evil actually stands in noble contrast to the real evil of self-seeking collectives. (A rather Randian sentence.) It’s easy to make fun of Rand for being a simplistic philosopher, bombastic writer and—I’m just saying—crazy old bat. But the 20th century was no joke. A hundred years, from Bolsheviks to Al Qaeda, were spent proving Ayn Rand right.A rather simplistic take in itself, I would have thought. I mean, O'Rourke himself notes this:
In “Atlas Shrugged” Rand set out to prove that self-interest is vital to mankind. This, of course, is the whole point of free-market classical liberalism and has been since Adam Smith invented free-market classical liberalism by proving the same point. Therefore trying to make a movie of “Atlas Shrugged” is like trying to make a movie of “The Wealth of Nations.” But Adam Smith had the good sense to leave us with no plot, characters or melodramatic clashes of will so that we wouldn’t be tempted to try.This really gets to what I don't understand: why does anyone need the over-the-top version of Rand's take on self interest and capitalism to believe that capitalism and more-or-less free markets have (in the broad sense) worked well? It seems to me that she took the obvious, inflated it beyond common sense, and then turned it into a cult.
But what really amuses me about the review is that this praise for Rand at the (shall we say) "meta" level clearly does not please the Randheads. One comment simply reads:
Are you reviewing the Movie or just happy to pan the views of Ayn Rand?And a lengthier one notes:
I find it interesting that a simple truth can be looked upon as so evil a thing byso many; One works hard. One is paid. One’s pay is immediately stolen via a rather shady progressive personal income tax that punishes anyone who actually tries. The more you try, the heavier the punishment. Seems in another age this would be called theft or craven evil by any sane person, but today, to raise objection means castigation.And on it goes. You get the drift.
There has been controversy about burning the Koran lately. It seems to me if you really want to cause trouble within the American political system, where Randian inspired politicians are on the rise (even though I reckon level of enthusiasm for Rand is inversely proportional to a politician's degree of common sense), have a campaign of Rand book burnings and public denunciations of her philosophy.
It would amuse me, anyway.

Mammals are interesting
Reasons not to take them seriously
I refer to a couple of stories in the media this morning. In the first, Lenore Taylor takes to task a specific example of Abbott scaremongering about the cost of a carbon price, noting that a large increase in a butcher's electricity bill is not quite what it seems, for the customer:
And Peter van Onselen in the Australian notes the Coalition figures who are taking hypocritical pleasure in the government's carbon price PR problem:For Greenwood, that [$4000 per year in increased electricity] is undoubtedly a significant extra cost. But he also told us his rough annual turnover, which allowed us to calculate that in order to pass on all that extra cost to his consumers, he would have to raise his prices by about 0.187 per cent.
For Greenwood's customers in Coffs Harbour that would mean T-bone steak at $22 a kilo would now cost … wait for it … . $22.04. Minced meat at $11 a kilo would now cost $11.02.
The indicative Treasury modelling released last week under freedom of information shows the average cost of a household weekly shop would rise by somewhere between 80 cents and $1.70, depending on whether the carbon price was set at the upper or lower end of expectations and whether it was allowed to flow through to the cost of petrol.
van Onselen reckons that Hunt has a broader leadership potential, and is being hobbled by having to do the hard sell on a Coalition policy that it he clearly can't genuinely believe is the best option.Climate change spokesman Greg Hunt, manager of opposition business in the House of Representatives Christopher Pyne, deputy leader of the opposition in the Senate George Brandis, shadow immigration minister Scott Morrison and countless other Coalition MPs are getting their media fix gloating about Labor's climate change woes in the here and now.
But they would do well to remember that in late 2009 each of them were arguing till they were blue in the face - with colleagues and through the media - that Turnbull should be backed in his efforts to pass the ETS. "You must price carbon if you want action on climate change" some bellowed. "If we don't pass the ETS we will be comprehensively routed at the polls," others exclaimed.
Hobbled he may be, but personally, I fail to see his broader public appeal. I don't find his media performances at all convincing, and (although this is admittedly a shallow assessment!) I have trouble getting over his strangely old fashioned hair and strained grimace that passes for a smile. (One has to admit, Howard was not always a natural smiley face either. Politicians can be convincing despite odd looks, but Hunt is far from achieving that yet, in my reckoning.)
