Over at ATTP, someone in a recent thread posted this 2011 video of Vaclav Smil explaining why carbon capture just never looked credible. It's great, and it's a sign of the dissembling that has gone on in climate change policy (even amongst the well intentioned) that it was given credence for so long:

Varieties of weirdness viewers
Beachcombing's Bizarre History Blog is a continual delight, and I was amused by this paragraph in a recent post which was, initially, about the number of people who have hallucinations:
Beach has had some experience with collecting fairy reports: that is children, men and women who believe they have seen an entity that they would describe as a fairy, here is a little (ahem) ‘wisdom’. Those who see fairies split neatly into two groups: there are the shamanic mystics and the Joe Publics. Mystics are individuals who have recurrent visionary events throughout their lives: the lady who is presently cleaning the Beach family kitchen has spotted fairies in the garden; she has encountered ghosts and she has ‘feelings’ and ‘instincts’ that she chooses to act upon. In short, she would have been burnt alive in the sixteenth century, whereas today she is pleasantly eccentric company and a bad influence on the kids. Joe Publics, on the other hand, are those who have never had these experiences prior to a one off bizarre event. Some will absorb it, some will ignore it, some will eventually discount it. Back in the sixteenth century they were doing the burning, and if they did see aliens with tin-foil helmets descending from the sky they shut the hell up or blamed their neighbours.
The second category is more interesting than the first, because their experiences demand more of an explanation.

The Atlantic has an extraordinarily good set of weekly photos up at this link. (Hope it's a permanent one.)
It includes this one, from China, the viewing of which alone makes me nervous:

On squeezing a teat
At this year's RNA Show, I forced the initially reluctant family into watching the very kid-centric milking and dairy display, but it was worth it all because we (wife, daughter and me - my son was too teenage to try) got to squeeze a cow's teat. Never done that before.
I asked the high school student (from Nambour State High, where they keep cows) who was supervising my handiwork closely "how many litres can you get from one milking", and after some consultation, I was given the answer - 25 litres (!).
I said that seemed an awful lot, but I was assured that a cow's milk producing parts extend way, way up inside her. I was given the impression that the tank, so to speak, extends well beyond the udder.
But, while not wanting to question the standards of Kevin Rudd's alma mater, I think the student was a bit misleading.
As far as I can tell, from this detailed slide show from the University of Wisconsin, where they seem to know a thing or two about cows, there are bits that help suspend the weighty udder that extend way up the internals of a cow:
but the parts that produce the milk are pretty much in the udder area:
In any event, on the question of how much milk you can get from a cow in a single milking, given that there are normally two milkings a day, and there are sites saying that an average cow can produce 35 to 50 litres a day, 25 litres at once seems certainly a possibility, if on the high side of the range. It's remarkable to think that, at a generous household consumption of 2 litres a day, one cow could make enough to keep 25 families happy.
While looking into this, I discovered that the Israelis are actually world leaders in coaxing high yields out of cows:
As just mentioned, the amount of milk cows are now enticed to produce is the subject of criticism from animal's rights groups. It is a pity that unwanted calves are killed at a very young age - something I have noted here before. In fact, it seems we don't even eat the meat ourselves:

It's remarkable to think that, at a generous household consumption of 2 litres a day, one cow could make enough to keep 25 families happy.
While looking into this, I discovered that the Israelis are actually world leaders in coaxing high yields out of cows:
The average cow in Israel produces 12,000 litres of milk a year, double what Australian dairy cows produce, at 5,500 litres a year (Dairy Australia 2014).
It could provide useful lessons for Australia, with our similar climate.
"The Israeli dairy industry is cutting edge technology for dairying," said Dr Ephraim Maltz, of the Institute of Agricultural Engineering at Israel's Volcani Centre.
Israel has pushed the boundaries of what dairy cows can do.Now, 12,000 litres a year is about 33 litres a day, if you count every single day of the year. But as I think they are "rested" before being pregnant again, this isn't inconsistent with a higher yield when they are milked. One animal's rights site says cows on average are milked 10 months of the year, so in Israel, that would indicate an average of 40 lives per milking day. Why is the Australian figure in the ABC report above much lower than that? Do they have more rest periods per year?
As just mentioned, the amount of milk cows are now enticed to produce is the subject of criticism from animal's rights groups. It is a pity that unwanted calves are killed at a very young age - something I have noted here before. In fact, it seems we don't even eat the meat ourselves:
Most will be destined for the slaughterhouse within days of birth. Bobby calf meat is considered to be of low value and is predominantly exported as ground beef and offal to Japan and the US.Hence there is an ethical reason for the search to make a genetically engineered, yeast based, milk equivalent. Good thing I handled a teat while there was still time...
Supersymmetry and the scale problem
To Avoid the Multiverse, Physicists Propose a Symmetry of Scales | Quanta Magazine
For some reason, this year old article turned up on my Zite feed, but I've decided it's blogworthy.
It's not a super easy article about supersymmetry (ha!), but it deals with an alternative idea that's being explored.
I see that multiverse cynic Peter Woit was quoting Joe Lykken (one of the physicists mentioned in the article) back in 2013 at Not Even Wrong with approval, so perhaps I should pay more attention...

Judging what works in education
Another NPR story, this time about a researcher in education from Melbourne, yet I am not familiar with him. As with all of education research, it may be that some of his claims are debatable, but I strongly suspect this one is right:
Update: I also note that Naplan results in Australia indicate that having a mother born overseas is a good way to stay above the average. Bit hard to address that in your education system, though....
Many education reformers tout school choice as a tool for parent empowerment and school improvement through competitive pressure. But Hattie says his research shows that once you account for the economic background of students, private schools offer no significant advantages on average. As for charter schools? "The effect of charter schools, for example, across three meta-analyses based on 246 studies is a minuscule .07," he writes.On the other hand, I don't quite understand how you study this at all:
Putting televisions in the classroom, on the other hand, has an average negative impact of -0.18. Holding students back a grade really does hold students back, with an effect of -0.16.How do you judge how the child would have done if they had not been "held back"?

A credible argument about Art?
People Love Art Museums — But Has The Art Itself Become Irrelevant? : NPR
As this guy argues about the success of "art museums":
As this guy argues about the success of "art museums":
They offer a titillating experience. Lively interaction with the peopleThe argument is not inconsistent with what I wrote about modern art and my reaction to it in 2009. (The post also remains the only time I have posted a photo of myself on the blog.)
around you, well-dressed people — it's exciting. But what has happened
is the art museum used to offer objects, works of art, the finest that
we have. And it's gone from offering objects to offering an experience.
...
There's the critical moment: 1978. I was in college at the time. It
was the King Tut exhibit at the Met: 1.8 million people lined up to see
that show. And that got the attention of the administrators — not just
of the Met but the trustees of every museum in the country.
This hadn't happened before. Museums tended to be doudy places run by
superannuated financiers who every year would write a personal check to
cover the deficit. They suddenly realized that, well, "I don't have to
cover the deficit if you can produce more of these blockbuster
exhibits."
I actually talk about this in the piece. It was almost 20 years to the day, 20 years after The Treasures of Tutankhamun, the Guggenheim did The Art of the Motorcycle.
And it was equally thrilling, equally successful, but it tells us that
our society can no longer distinguish — effectively distinguish —
between a Harley-Davidson Sportster and a 3,000-year-old golden mask
from Egyptian New Kingdom, can't make a qualitative judgment about
intrinsic value.
So, the museum seemed to be more and more successful, but there's been a little bit of a bait-and-switch that's going on behind the doors of many.

The dodgiest bit is the flywheel system for "dynamic stability".
I wonder if such a tower would be a good base from which to then grab onto an orbiting skyhook tether with which to get into orbit? Maybe just need a short launch up, clear of the tower, to be snared by the hook...

Why does the US presidential gene pool seem so shallow?
There seems something distinctly "off" about the US political system when it keeps throwing up Presidential candidates that seem so underwhelming to the rest of the world. I don't really remember when I last felt particularly impressed by the qualities of a candidate. I didn't even think Obama was impressive; he certainly seemed under-qualified, and his promise of "hope and change" was very much like the shallow sloganeering of the Kevin Rudd ascendency. (Although, as it happens, I think Obama has turned out to be a pretty good President, after all. His recent interview with David Attenborough showed an intelligent and decent man, even if his image is assisted by the comparison with the dimwittery that has enveloped his opposition. His legacy in terms of health care reform, getting serious about some action on climate change, and on dealing with difficult economic circumstance, will stand him well in future, I think.)
Dismissing the Trump clown show, as far as I can tell Jeb Bush still seems the most likely Republican candidate. As many have noted, it's funny how Americans rebelled against dynastic rule a couple of hundreds years ago only to more or less endorse another form of it now.
Of course, everyone knows I follow the Krugman line that the Republicans have gone mad, and is currently a lost party that needs some very dramatic changes before it becomes credible again. But even on the Democrat side - I have never followed the Clinton family story closely, but remember how vigorously Hitchens condemned them, and I worry when any politician seems prone to self-aggrandising flights of exaggeration such as Hilary has displayed in the past. (Shades of Reagan telling movie anecdotes, apparently believing they were true, if you ask me. And no, I never thought highly of Reagan, even before it was known he was well on his way to dementia while still President.)
As for the only other Democrat candidate I have heard mentioned - Joe Biden?? Really? He may be a decent enough fellow, but I had the impression he was mainly notable for making silly gaffes and had a distinct "Dan Quayle" feel about his vice presidency.
The amount of money that anyone needs to run for President in that country seems truly ridiculous, but I still don't really understand why that results in candidate runs by people who fail to impress. Or is it just me, feeling underwhelmed ever since the last Kennedy was shot? I do feel a bit hypocritical, because with John Howard, I sort of liked the way he was underwhelming in physical presence and in oration, but thought he displayed relatively sound judgement and decency and that this is what matters at the end of the day. Perhaps it is because of the charisma of the Kennedy family that I feel the US leader should be impressive not just in deed but in appearance and campaign rhetoric too.

The more important story
While the political sideshow of an incompetent and rudderless government sucks up most coverage (as well as media sympathies on gay marriage as the greatest injustice the nation has ever seen, apparently), the truly important story of the government's actual punishment of those people detained in Nauru and Manus in order to stop others leaving Indonesia gets short shrift.
This should have been the lead story in the media this morning, and on 7.30 last night.
Still, they did a decent job, the ABC, and it's pretty disgraceful that there is not more attention paid to this issue. (It doesn't even appear on The Australian's front web page, as far as I can see. Fairfax and The Guardian feature it fairly prominently.)

About bicycle helmets
I'm not going to die in a ditch (allusion to not wearing a helmet not really intended) defending compulsory bicycle helmet laws, as I think that a more moderate legal line in use of bicycles generally in this country may be justifiable. (For example, if, as in Japan, the population was polite enough that cyclists could be trusted to ride at moderate speed and cautiously on urban footpaths, I wouldn't mind seeing that permitted, and for those who ride in such a manner not to be required to have helmets. Those who use dedicated bicycle lanes that are on the road - they can be treated differently.)
But still, people who say things like this:
In fact, let's look at the actual link at the claim, and here is what it says:
As for other reasons why the "never cycled as an adult in Australia" are not about to take it up now: the professional amateur cyclist (by which I mean "anyone who has ever wore bicycle pants - while on a bicycle") has probably done a greater deal of harm in the last 25 years than helmet laws which, I suspect, most adults have come to accept as sensible precaution. How? By frequently acting like entitled jerks on the road, and even on cycleways.
But still, people who say things like this:
But critics claim that helmet laws put people off cycling, causing far wider weight-related health problems due to Australians favouring driving, or not moving at all. One study found that 16.5% of people say they would ride more often if they were not required to wear a helmet at all times.should at least exercise some skepticism about what people say they would do were it not for factor X, especially when it comes to health matters. Just how many people would say, for example, that they know they should lose some weight, and will they take steps to do so, and then never quite get around to it?
In fact, let's look at the actual link at the claim, and here is what it says:
Oh really? Having to wear a helmet is just about the least of their reasons? That's not the impression that article initially gave.So what are the things that are preventing over 50% of the population from hopping on a bike, and what can our governments do to help the situation? Here’s what the they said was stopping them:
- Unsafe road conditions: 46.4%
- Speed/volume of traffic: 41.8%
- Don’t feel safe riding: 41.4%
- Lack of bicycle lanes/trails: 34.6%
- Destinations too far away: 29.9%
- No place to park/store bike: 23.5%
- Do not own a bike: 22.5%
- Weather conditions: 22.1%
- Not fit enough: 21.8%
- Too hilly: 19.6%
- Don’t feel confident riding: 18.6%
- Not enough time: 16.7%
- Don’t like wearing a helmet: 15.7%
- No place to change/shower: 14.6%
- Health problems: 14.4%

Modern marriage
I don't write much about same sex marriage because: it is, without doubt, the trickiest topic to address without feeling that you're hurting someone's feelings without actually wanting to; sexuality is actually a difficult matter theologically given that all types of relationships involving sex can be loving ones and God's supposed to be about love; and some of those on my side of the issue (against it, basically, while accepting that it appears virtually inevitable) are people:
1. only too willing to use derisive and insulting language with respect to homosexuals;
2. make it clear that they have a problem with homosexuality merely because they personally find the very idea of some forms of sex repulsive; and
3. have the worst possible judgement on the matter of actual great significance to the future of the planet*;
and as such it's embarrassing to be on their side.
Nevertheless, here we go:
a. I'm sorry, is this just an age related thing?, but whenever I see a same sex marriage ceremony on TV as part of their advocacy for a change in the law, I cannot help but feel it looks like a parody of what I, and (let's be truthful here) several billion other people both now and over history, have understood as a wedding. I have my doubts I'll ever get over that feeling, especially when you see things such as female couples in bridal gowns, cutting of wedding cakes with same sex couples on top, etc.
b. While we're being frank here, I've noticed what I think is an increasing strain of victimology coming in to some of the advocacy, particularly for those who claim that not being able to marry has made coping with their sexuality much harder psychologically. This at first blush sounds very plausible, but I was just checking around again on the matter, and as far as I can tell, homosexual people even in remarkably gay endorsing countries such as England still seem to suffer about twice the rate of mental health issues compared to the general population. Now, sure, I guess that no matter how many gay celebrities are on national television and how gay friendly your national laws are, being gay may well still cause tension and difficulties within families, and that can account for some incidence of depression and other mental health issues.
But....that being the case, and while fulling acknowledging that gay people were genuine victims of some appalling legal treatment via the criminalisation and medical definition of of their sexuality until quite recently, it seems near certain that gay marriage is not going to be a dramatic cure all for the increased rate of mental health issues which gay people suffer from.
Of course, the argument could be made that, even if the "gay gene" carries with it a predisposition to greater susceptibility to things like depression, that's all the more reason to remove any possible social reason as to why they might feel left out and unhappy. Maybe. But I still think some SSM advocates are overselling the benefits of this law reform as a cure all for what makes them - OK, some of them - unhappy. It reminds me a bit of the cases of the rich and ostensibly successful who find themselves puzzled because there is no longer any obvious reason why they still feel depressed much of the time. (Stephan Fry might fit into that category.)
c. I thought that Katy Faust last night on Lateline was actually not a bad advocate for the conservative position - but it's terribly unfortunate for the sake of the political and social argument that she is Christian. I have never heard of her before, and maybe if I read some of her stuff I might not find her as good as she appeared last night, but it seemed to me that her argument was not religiously based, but SSM advocates will dismiss her views because she is religious.
d. As Katy Faust would seem to agree, much of the issue that conservatives have with SSM is actually more to do with how SSM inter-relates with child bearing and child rearing. But heterosexual use of reproductive technology broke the ground for that, so there is no doubt that there has been a "slippery slope" effect in social views. Conservative Catholics would argue this started with modern contraception severing the natural connection between sex and child bearing, and as much as I disagree with them on the validity of trying to hold back the tide of improved methods of contraception, I have to admit it is a fair enough argument. The problem is, by over-reaching on the matter of how proscriptive they could be on the matter of what sexual acts are automatically against God's will, they lost all credibility for drawing lines anywhere else on matters of sex and reproduction amongst everyone except Latin loving Mass types, who also invariably happen to be nuttily against science on climate change.
e. On the matter of social attitudes towards reproductive technology and child rearing, people on the SSM side seem to always be inadequately acknowledging the degree to which they can change back to more conservative positions. Use of anonymous donor sperm is a great example of this: it was all the rage for a while there, and advocates for "anything goes" at the time never seemed to credit the importance with which the children from such a system could come in future to view knowledge of their biological parent.
It seems to me that with surrogacy, we could entirely face the same backlash in future, and all the gossip magazine current coo-ing over gay men happy with their adorable new baby pushed out by some well paid poor woman in India is not going to change that. (I find it deeply ironic that it tends to be women's magazines that see to be so gushing over celebrity gay male families using surrogacy. One commercial use of a woman's body is fine and dandy, apparently, yet a male celebrity using a prostitute doesn't get quite the same reaction.)
Even with lesbian couples, people seem blithely unwilling to question the matter of the relationship of the child with the biological father. Now, unlike commercial surrogacy, it may be that some such couples will be on good terms with the father who the child may always know (and, in fact, he may be something of a father figure to them if he is with them enough.) But it's clear that to a great many SSM advocates that this simply does not matter enough to even question - I'm thinking the case of Senator Penny Wong, for example - it's the fulfillment of the lesbian couple that counts. As with those who were thinking 30 years ago that anonymous sperm donation would never matter to the kids resulting, this is just a patently shallow attitude that is, in effect, the mere intellectual fashion of the moment.
f. Having said all of this, the popular tide of opinion, especially amongst the young, is strongly for gay marriage, and it appears socially inevitable and will not mean the downfall of civilization, so I don't quite understand why Tony Abbott, if going for a plebiscite on the matter, would not just bring it on for the next election.
I think it is pretty clear that however Abbott proceeds, it will come in, and any approach which is seen to be dragging out the inevitable only hurts him politically.
In order to keep face with his supporters, such that they are because, let's face it, he is a failure of a PM and you have to be nuts to disagree, the plebiscite idea is not a bad one. But why delay it for 3 years?

As with those who were thinking 30 years ago that anonymous sperm donation would never matter to the kids resulting, this is just a patently shallow attitude that is, in effect, the mere intellectual fashion of the moment.
f. Having said all of this, the popular tide of opinion, especially amongst the young, is strongly for gay marriage, and it appears socially inevitable and will not mean the downfall of civilization, so I don't quite understand why Tony Abbott, if going for a plebiscite on the matter, would not just bring it on for the next election.
I think it is pretty clear that however Abbott proceeds, it will come in, and any approach which is seen to be dragging out the inevitable only hurts him politically.
In order to keep face with his supporters, such that they are because, let's face it, he is a failure of a PM and you have to be nuts to disagree, the plebiscite idea is not a bad one. But why delay it for 3 years?

Combining solar farms and agriculture
Japan Next-Generation Farmers Cultivate Crops and Solar Energy - Renewable Energy World
I had been wondering about this for some time: lots of Australian farming land is flat, expansive fields in parts of the country where (I would have thought) the sunlight is of such intensity in summer that it's probably more than strictly necessary for most crops. In fact, some shading in the height of summer might be useful for decreasing soil drying.
So, is it possible to successfully combine large scale solar panels with useful agriculture beneath them?
From the link above - yes, it would seem that it is.
Worth looking into for Australia, isn't it?
Update: here's a paper from France looking at how some crops go under partial solar panel shade. Seems it can be made to work OK.

On finding other planets
Matt Ridley on filters | …and Then There's Physics
The astronomer who blogs about climate change has an interesting post up after the difficult work of finding other, potentially habitable, planets. (And climate change still gets a mention, too.)

A PM with scant authority in his own party room
Given all of the turmoil that Gillard had to face with disunity, along with an opportunistic policy windvane of an Opposition Leader, it's quite ironic to see from this report by Phil Coorey that Abbott seems to be having a lot of trouble convincing his own backbenchers to follow his preferred tactics.
Even more amusing was the last bit:
Even more amusing was the last bit:
The party room discussion comes amid growing unrest in the Coalition over Mr Abbott's leadership just six months after he survived a spill.
News of the push leaked while the party room meeting was underway. This caused angry scenes inside the party room as to who was leaking, according to further leaks.I tell you what: when Abbott goes, he's not going to be feted on the talk circuit by those on his side of politics as a basically good PM thwarted by circumstances, like Gillard. He is, undoubtedly, going down in history as one of our worst Prime Ministers by the reckoning of all sides of politics.
Mad film noted
Hard to Be a God review – mud, blood and holy hell | Film | The Guardian
This film seems to be in the category of "so bizarre, it might be worth seeing":
This film seems to be in the category of "so bizarre, it might be worth seeing":
This monochrome dream-epic of medieval cruelty and squalor is a
non-sci-fi sci-fi; a monumental, and monumentally mad film that the
Russian film-maker Alexei German began working on around 15 years ago.
It was completed by his son, Alexei German Jr, after the director’s
death in 2013. If ever a movie deserved the title folie de grandeur
it is this, placed before audiences on a take-it-or-leave-it basis:
maniacally vehement and strange, a slo-mo kaleidoscope of chaos and also
a relentless prose poem of fear, featuring three hours’ worth of
non-sequitur dialogue, where each line is an imagist stab with nothing
to do what has just been said....
It is set in what appears to be a horrendous central European village of
the middle ages, as imagined by Hieronymus Bosch, where grotesquely
ugly and wretched peasants are condemned to clamber over each other for
all eternity, smeared in mud and blood: a world beset with tyranny and
factional wars between groups called “Blacks” and “Greys”. In the midst
of this, what looks like an imperious baronial chieftain called Don
Rumata, played by Leonid Yarmolnik, walks with relative impunity: this
sovereignty is based on his claim to be descended from a god....
Each shot is a vision of pandemonium: a depthless chiaroscuro
composition in which dogs, chickens, owls and hedgehogs appear on
virtually equal terms with the bewildered humans, who themselves are
semi-bestial. The camera ranges lightly over this panorama of bedlam,
and characters both important and unimportant will occasionally peer
stunned into the camera lens, like passersby in some documentary.
