Hydrogen on Earth, Oxygen on Mars
His objections about the economics of making, transporting and storing hydrogen all sound pretty convincing, but it would be good to see who disagrees with him.
His suggested practical solution to US dependence on oil sounds somewhat more credible: the government to mandate "flex-fueled" cars, which can run on any mix of alcohol or gas. Interesting, although it doesn't help that much on the greenhouse gas issue, does it?
Meanwhile, Zubrin's ideas about terraforming Mars are set out in Popular Science here. All it takes is a 1,000 years to have a habitable atmosphere. (Mind you, it also involves things like crashing 40 asteroids on the planet.) It is, perhaps, the plan you would use if you had unlimited money and foolproof technology.
At least you can't accuse him of thinking small.
UPDATE: the prospects for a legislative requirement for flex fuel cars are looking up. See this CSM article which goes into some detail.

Some Iraq posts
Francis Fukuyama thinks that modern radical Islam can correctly be described as an outgrowth of modern "identity politics". His article about this is broad ranging and interesting, as it talks about the origins of identity politics in the first place, but I sure that there are grounds on which to disagree. If he is correct, he argues that it has this unfortunate consequence:
...the problem of jihadist terrorism will not be solved by bringing modernisation and democracy to the middle east. The Bush administration's view that terrorism is driven by a lack of democracy overlooks the fact that so many terrorists were radicalised in democratic European countries. Modernisation and democracy are good things in their own right, but in the Muslim world they are likely to increase, not dampen, the terror problem in the short run.
Note the last words there. Maybe in the longer run it still is likely to help end it?
Like I said, I am not entirely convinced by his argument, but it is interesting.
The Moon becomes more dangerous
It had been thought that the X-rays were not copious enough to be a major hazard, but a new study suggests X-rays really do pose a threat to astronauts working outside of protective spacecraft or bases. The research was carried out by David Smith at the Lunar and Planetary Laboratory in Tucson, Arizona, US, and John Scalo of the University of Texas in Austin, US.
Using the observed rate of solar X-ray outbursts of different magnitudes, they worked out that a lunar astronaut has a 10% chance of receiving a dangerous dose of X-rays from a solar flare for every 100 hours of activity outside of shelters.
The level of radiation they consider harmful is 0.1 Gray or more, which can cause bleeding ulcers and other internal damage, and would certainly increase an astronaut's risk of cancer. The Sun has even produced flares that could kill an unprotected spacesuited human on the Moon, they say, although these are extremely rare.
Astronauts working far outside need to have an x-ray umbrella with them for protection from such outbursts.It's sad that Robert Heinlein's stories of boy scouts camping on the Moon are not likely to ever come true. (Exploring deep lava tube caves might still be an alternative, though.)

The Left and Iraq
His story is similar to Christopher Hitchens: he comes with excellent Left credentials, completely understands why the Left criticised Western support of Saddam in the 1980's, but argues that it is the Left which changed its stripes and became hypocritical in its approach to the Iraq war and its aftermath.
This has puzzled me for some time. The anti-War Left feels vindicated over the issue of the justification for war. Fine, let's not quibble over the actual details, which they constantly misrepresent, and just assume for the sake of the argument that the decision to invade was a grave error, and even an immoral act. (This is just "for the sake of the argument" talk, remember.)
Second point: does any serious analyst anywhere in the world suggest that the withdrawal of coalition forces at any point up to and including now would have meant immediate greater stability in Iraq and the region? Not as far as I know.
The crux of the matter then is this: how does promoting a step that would now make the average Iraqi's position worse suddenly become defensible from the moral high ground that the Left supposedly occupies?
Cohen explains it this way:
There was too much emotional energy invested in opposing the war, too much justifiable horror at the chaos and too much justifiable anger that the talk of weapons of mass destruction turned out to be nonsense. The politically committed are like football fans. They support their side come what may and refuse to see any good in the opposing team. The liberal left bitterly opposed war, and their indifference afterwards was a natural consequence of the fury directed at Bush.
It is a fair argument, which I've heard many times, although I wince at the implied passivity. People don't just react to a crisis: they choose how they react. If a man walks down the street trying to pick a fight, you can judge those he confronts by how they respond. Do they hit back, run away or try to calm him down? The confrontation is not of their making, but they still have a choice, and what choice they make reveals their character and beliefs. If you insist on treating the reaction to the second Iraq war as a one-off that doesn't reveal a deeper sickness, I'll change the subject....
The anti-war movement disgraced itself not because it was against the war in Iraq, but because it could not oppose the counter-revolution once the war was over. A principled left that still had life in it and a liberalism that meant what it said might have remained ferociously critical of the American and British governments while offering support to Iraqis who wanted the freedoms they enjoyed.
Cohen argues that no such support was offered. (I note that those European countries which opposed the war might have grounds to argue that their troops' lives should not lost because of an error of the pro-War countries, but even so, have they tried to offer diplomatic or other assistance of any form between the regional powers?)The likelihood of success of the current "surge" is hotly debated, which is fair enough. (Even Hitchens seems fairly pessimistic about it.) I freely admit to not knowing enough to really be able to judge its chances of success; Bush's critics on this issue all appear to be armchair experts on counter-insurgency tactics. (That some retired Generals oppose it is far from conclusive; some of those still around must have given it support, and in a situation as politicised and unique as this one, dissenting voices even within the military are to be expected.)
If the surge fails, and the political process within Iraq is unable to rise above sectarianism, there will be a point in the future where the US will have to exit as gracefully as possible. But the problem Cohen writes about is the anti-War Left's immediate isolationism after the fall of the regime and continuing today. It is not a position that should be held with pride.
Porn and technology
But apart from that, the article points out that the porn industry is worth a lot of money:
Although the vagaries of entertainment accounting have become legendary, it is universally acknowledged that the U.S. adult-film industry, at around $12 billion in annual sales, rentals, and cable charges in 2006, is an even grander and more efficient moneymaking machine than legitimate mainstream American cinema (the latter's annual gross came in at $9 billion for 2006).
Figures of around $10 billion a year always interest me, because that is getting pretty close to the budget of NASA. (Well, now it's up to close to $17 billion, but as recently as 1999 it was only $13 billion.)
This may be a handy figure to keep in mind when you next have to argue with someone who whines about the expense of the space program. People hear "billions" and without context it means nothing.
Also, with figures like this, is public direct sponsorship of a space program really out of the question? All we need is an entrepreneur who is out to raise money to set up an orbiting studio specifically to make zero-G porn. (All the earth bound variations of sex were surely filmed by about 1985 anyway. ) Richard Branson is probably already considering a sex hotel anyway, I reckon.

Hitchens steps up to praise Steyn
Super fit to super dead
I therefore take some mean spirited pleasure from reading this:
People who regularly take part in endurance sports could be putting their lives at risk from damage to the right side of the heart, research suggests.
Marathons and triathalons are fast-growing events, more than 10,000 people regularly running, cycling and swimming long distances. But the super-fit athletes who train hard for such races can develop a life-threatening condition called ventricular arrhythmia (VA), in which the heart beats at an irregular rate and rhythm, according to the Belgian study. The condition increases the chance of sudden arrhythmic death syndrome, which kills 500 healthy Britons a year.
So, it's essentially a pointless activity that can also induce heart problems. Ban the fun run, I say!From the "only in Japan" files
Here, you can choose from a wide selection of delectable delights ranging from Spam to asparagus, and enjoy them in their purest form -- straight out of the can. No need to heat anything up (there's no oven on the premises), no need to have a waiter deliver the dish to your table and no need for fancy plates or silverware, as management thoughtfully provides plastic spoons and forks upon purchase. After you've ordered, pull your food and drink up to one of the steel barrels that serve as tables in the dining area, which is actually a bare lot, open to the air in summer and enclosed with plastic sheeting during the colder months....

You might well ask why anyone would pay to eat cold food out of a can?
"It's a combination of the friendly atmosphere and the novelty of the place," explained one customer. "A lot of people I know have started coming here."
I have an idea for Australia: this might be the simplest cafe franchise system, ever!
Maxine on board
As for Maxine McKew working for Kevin Rudd: well, being married to a Labor identity has long indicated where her sympathies lie, but from the way she has conducted interviews over the years I have always assumed she has quite moderate and reasonable views. It's no surprise that she is helping Rudd, and if she makes the party more centre or right wing, good on her.
And you thought the Pope was blunt
The Orthodox Greek church is not impressed:
The move is bound to aggravate the highly conservative Greek Orthodox church, which strongly disapproves of what it regards as paganism.
"They are a handful of miserable resuscitators of a degenerate dead religion who wish to return to the monstrous dark delusions of the past," said Father Efstathios Kollas, the President of Greek Clergymen.
I wonder how many ecumenical conferences he's been to...

Comet success
OK, you have to click on it to enlarge to see the comet at all, but it's there, top right.
While trying to get a better shot, I accidentally used manual exposure, and it ended up at 30 seconds, using the car roof to steady the camera. Lucky accident, as this was the result:
Much better!
Pilger Alert! Pilger Alert!
From the reader comments which follow the article , I like this one:
John Pilger has it completely correct. I returned to live in Australia in Oct 2005 after a number of years in Europe and was horrified at many of the changes. Muslim-bashing is rife, far worse than anything I saw during 1991 during the first Iraq war and is actively, personally vicious.
The author of that comment is "Bobthekelpie," whose nick I have seen before on an Australian blog, I suspect.

Running away from the fight
(Tigerhawk's position on global warming seems close to mine.)
Only a hundred years ago...
Having a browse through it, I get the impression that the Western world has changed a lot more between, say, 1915 to 1965 than it has in the last 50 years. Here are some extracts as examples (except for the section headings, all bold has been added by me):
Psychic Changes at Puberty. -- The angular, gawky feeling gradually disappears; the girl becomes self-conscious; new impulses arise, and she gives up many of the hoydenish ways of childhood. The girl's imagination is more lively, and just at this time mathematics form an excellent subject for mental occupation. The girl now begins to question the whys and wherefores, and demands reasons for the course that is laid out for her, and is full of ideas of her own; so that while as a child she had accepted almost unquestioningly the commands of her parents, she can be managed now only through the power of reason. And this is just as it should be, for the girl has reached the years of discretion, and now is the time when her reason and judgment are capable of rapid cultivation.
My comments: Well, why hasn't my range of books "Mathematical Amusements for Modern Young Women" volumes I to IX been running off the shelves, then?
Interesting how the current idea is that there is a 90% probability that you won't be able to reason with your young teenage daughter. People talk about children "growing up too quickly" now, but the issue is perhaps more to do with how young adults get independence without associated expectation of substantial domestic or social responsibility. Anyway, back to the good doctor:
Shall Husband and Wife Occupy the Same Bed? -- Among civilized nations custom differs in this regard; in Germany, for instance, the husband and wife occupy separate beds in the same room; formerly in this country it was almost the universal custom for husband and wife to occupy the same bed. The current of opinion has changed in this respect, and it is now considered in the highest interests of both that they shall occupy not only separate beds, but separate rooms; these rooms communicating through a door which connects their respective dressing-rooms. This is unquestionably the best arrangement from the hygienic as well as from the ethical point of view....
She's very precise with her recommendations, isn't she?
The Marital Relation. -- It is most important for the interest of both parties that there should be chastity in the marriage relation as well as out of it. Many young couples have had their lives ruined by excessive sexual indulgence. The effect is usually most severe upon the husband, yet the wife becomes weak, nervous, and excitable. Sexual excess is also the grave of domestic affection. The general rule given is that coitus should never take place oftener than every seven or ten days. When coitus is succeeded by langour, depression, or malaise, it has been indulged in too frequently...
When the conjugal act is repeated too often, the man will become gradually conscious of diminished strength, diminished nerve force, and diminished mental powers. Excess weakens a man's energies, and enervates and effeminates him. Moreover, it renders him liable to an infinity of diseases and a readier victim to death. Not only is the strength of the constitution lowered by the excessive expenditure of force and matter requisite for the perpetuation of the species, but this lowered standard of vitality is transmitted to children. There can be but little doubt that this is one of the reasons why so many healthy parents beget sickly children, who die early. They have exhausted themselves of the material from which a new life is created, and so it is not properly started at the beginning and never reaches its highest development...
Nothing like laying on the guilt to the parents of a lost baby by telling them "it's because you had too much sex"!
I also like the suggestion that too much sex saps the man's energy, while it makes the wife "nervous and excitable".
About the bowel:
Regularity in this, as in all other habits of life, is most essential, and the individual should go to the toilet at the same hour every day, even if there is no inclination to have a bowel movement, and thus the habit will be established; the most convenient time is directly after breakfast.....
But should the patient have gone so long without a bowel movement that all these means fail, it will be necessary to precede the water enema with one of oil; or still more effective is the following combination: take one teaspoonful of the spirits of turpentine, the yolk of one egg, and two tablespoonfuls of olive oil, and beat well together, and add to these one pint of water at a temperature of 110 degrees F.
Hmm, I wonder if using enemas which include "spirits of turpentine" helps cut down on toilet cleaning too?

A David Byrne fan
The NYT has an article about his many and varied artist endeavours of recent years. He also has a long running blog of sorts at his website, which I have been meaning to recommend for ages. Sure, he's as left wing as you would expect any New York avant garde artist to be, but his journal is well written, philosophical, covers his broad ranging and somewhat esoteric interests, and is generally more or less optimistic and cheery in outlook. He's still very cool after all these years.
The genre that refuses to die
Loose lips sink her ship
Tim Dunlop, who is going to need years of therapy if Labor loses the next Federal election, therefore has to spin this as perhaps not really influencing how people vote. Let's face it Tim, it's not exactly a vote winner though, is it?
It's also odd timing that the Julia interview comes after Nancy Pelosi is held up by the media in the States as a groundbreaking example of a woman succeeding despite having a whole houseful of children. Mark Steyn's commentary on this was the most interesting.
The thing is, I reckon there are ways Julia could explain her life and attitudes which would, even if not all that genuinely felt by her, not be able to be nitpicked by either side. She just hasn't learnt how to do that yet.
She can send me money if she wants my advice, though.
Update: just to fend off some possible criticism of this post: I am not saying that all conservative attack on her will be fair, but at the same time I think there is a sizeable slab of the breeding population (not all of whom vote Liberal) who share my social conservative instinct to prefer as politicians men and women with children, or at least those who seem to like children enough to have wanted some if circumstances allowed. On the other hand, there will be Labor supporting feminists who are not going to be comfortable about the spin that can be put on her seeming "can't have it all" attitude.
My main point therefore is that she is too good at setting herself up for attack from both sides with this sort of talk. She should either decline to talk about it at all, or find the ways that do pre-empt attack.
Update II: Hmm, it's at least 12 hours and still no post at LP about this. I am surprised. Should I be worried if I can't predict what will or won't get them posting? Nah, not really. Maybe they are too busy reviewing old posts for entry into some new competition for best opinion writing from a soft left perspective.
