Scientists Make Oxygen Out of Moon Rock

Based on experiments with a simulated lunar rock developed by NASA, the researchers calculate that three one-meter-tall reactors could generate one tonne of oxygen per year on the Moon. Each tonne of oxygen would require three tonnes of rock to produce. Fray noted that three reactors would require about 4.5 kilowatts of power, which could be supplied by solar panels or possibly a small nuclear reactor on the Moon.

I wonder, how long does a tonne of oxygen last for, say, a dozen people?

Presumably, find frozen water on the Moon would make oxygen production easier.

There was a lengthier version of this story on Nature News, but I think their stories still disappear behind a paywall after a short time.

The perpetual teenager

Pew, that was a lucky escape | theage.com.au

Catherine Deveny writes about Catholicism, her childhood religion, with all the subtly and wit of a 15 year old know-it-all flaunting a new-found sexuality and atheism to annoy her parents. (That is, with none at all.) Trouble is, she's 40.

I also wonder about this section:

The priest, obviously drawn by the unusual sight of new people, approached us to welcome us to his flock. I shot out my hand. "Hi, I'm Catherine."

All the blood drained from his face. "You're that writer?" "Yes," I replied. I happily introduced my sons, who, in an uncharacteristic display of manners, shook the priest's hand and said, "Nice to meet you." The priest wandered off in a daze. Or was it a trance? Maybe it was religious melancholy.

Why would the priest even recognise her? Unless she gave warning of her attendance (and why would she bother doing that?) I would be quite surprised that she would otherwise be known to him.

She's seems profoundly proud of her kids being brought up as free thinking libertines:

After surveying the ''good news'' of carnage and damnation on the wall, the 11-year-old asked what a virgin was. I explained. Then he said, "Is there something wrong with sex?"

We know what her answer would be. One gets the impression from previous columns that she intends to be terribly non-judgemental and open-minded to the point of quasi-encouragement to experiment, probably as a continuation of her resentment of her parents trying to set some boundaries for her. (Just a guess, there, but she does write in her column today how a comment made in the car by her father, about another family, made her want "to jump over the front seat and ram my father's head into the windscreen".)

If there is any justice, at least one of her kids will have a conservative rebellion and end up very religious. It will, hopefully, annoy Deveny no end.

The real Big Day Out

Time for a report on the trip to the Brisbane Exhibition last Sunday.

If it was up to me, I would arrive at 9am and leave at 9.30pm, but my wife is not from these parts, and considers that to be just a ridiculously long day. (You have to be born and raised in Brisbane to have the inordinate fondness for the place that quite a few of us here share.) I think she actually threatened last year to just leave me to take the kids this time, but somewhere in the intervening 12 months she changed her mind, and ended up a relatively happy participant. She missed my daughter - now 6 - telling me in the afternoon, without prompting, that it was "the best day ever". I passed the message on to my wife with a small degree of smug satisfaction.

[Later in the day, I observed to my wife that it is pleasing to see a lot of Asian and other immigrants at the show. She claimed it was because Brisbane was short of entertainment anyway, and people just go to whatever is on. As you can see, the brainwashing has some way to go yet.]

Before I leave the topic of the marital dispute over the exact degree of enjoyment an adult can appropriately extract from the Ekka, I should also mention that I took my aged mother along this year too. (She resisted getting in the car at first, but after a bit of shoving she accepted her fate.)

We arrived at about 11am, and left after the fireworks at 8.45.

So this year's highlights:

* new lambs in the sheep birthing place were cute (but we didn't actually see one being born)

* I get happiness from the fact that my kids chose relatively cheap buys in the show bags, yet were very satisfied. The boy takes the show as an opportunity to weaponise himself for the following 12 months, and this year he was happy with one $10 machine gun that, I must admit, I would have liked as a boy too. The girl went for a cutesy pet bag with lots of stationary in it.

* the "jet truck" was new and kind of slow and pointless, except it did make a very big flame that is pretty spectacular.

* we all decided that the latest rides look downright dangerous, and potentially not just to the riders. The current new types seem to involve variations on a theme of long arms which spin people sitting at the end around in a vertical circle. Why anyone thinks this is fun is beyond me; I can barely stand the roller coaster type rides at Disneyland, where one feels Uncle Walt surely wouldn't scare you to death. (Space Mountain is probably the strongest ride I have ever been on.) Not being a fan of the falling sensation, this looks particularly horrendous to me:




It's also clear that if there is a catastrophic failure, then, depending on the exact point of the circle it happens, the passengers could end up some distance away and take out many passers-by. I certainly did not like to stand in the plane of the ride, just in case.

Anyhoo, a pleasant day was had by all, even though my mother elected to stay the night but by the end decided she really was too old to spend that much time there. I pointed out that she was giving up to easily: there is always the wheelchair option when she's 90. (She's only got 5 years to reach that milestone.)

Finally, I note that big re-development of the site is finally going to get underway, which means that residential units and some all year round commercial use will be allowed on parts of the land. (As I recall, it is all owned by the Royal National Association, and the Council and State government have been lusting after the re-development potential of the place for decades.) This report gives an idea of some of the changes. I am not sure how it affect the Ekka itself; it's hard to imagine some of the old buildings gone. But the upside is: maybe I can retire there, as one of the blessed 10,000 residents. Not quite like living in Disneyland, but still...

Talking about solar

I see someone in the Economist talks about his options for domestic solar power in the US, and how it has become significantly more affordable in recent years.

I know that everyone says that solar power does not make economic sense at the moment, but there is one thing I think people don't factor in: the strong appeal of semi-independence from the grid.

On the weekend, I made my annual pilgrimage to the Brisbane Ekka (a longer post will follow), and I did notice a lot of people asking at this company's display about its domestic solar cells. I think the price was something like $2,995 for a 1.5 KW system. (After rebates I presume?)

I've never looked into it much, but from what I can gather, anything less than 2 KW is hardly worth the effort. Still, I think people just like the idea of not being so reliant on the grid, even if the cost is no where near going to be recovered in electricity savings.

If (as seems certain) an ETS is going to send up electricity costs pretty quickly, the appeal of solar is surely going to increase, although again it may not actually make economic sense. If an ETS encourages more people to install solar, and thereby reduce the drain on coal fired plants, that appears to be a good thing. The issue, I suppose, is at what cost to the government, as I presume that solar will still only succeed (in the sense that many people will buy it) with heavy government rebates.

If the money the government spends on supporting solar could be spent in other ways that are more effective at reducing CO2 from coal fired plants, then it's not such a good idea.

All I am saying is that experts should not overlook the inherent appeal of free electricity from the roof.

Appleyard takes on the Godless (again)

Bryan Appleyard reviewed a book "The Evolution of God" in The Times on the weekend, and now has followed up with an entertaining and interesting post on his blog.

Rich on US woes

Op-Ed Columnist - Is Obama Punking Us? - NYTimes.com

Frank Rich has an interesting column on Obama and the increasing perception that the US system of government is more-or-less corrupted wholesale by lobbyists. He ends with this:

The best political news for the president remains the Republicans. It’s a measure of how out of touch G.O.P. leaders like Mitch McConnell and John Boehner are that they keep trying to scare voters by calling Obama a socialist. They have it backward. The larger fear is that Obama might be just another corporatist, punking voters much as the Republicans do when they claim to be all for the common guy. If anything, the most unexpected — and challenging — event that could rock the White House this August would be if the opposition actually woke up.

Sunday scandal

Sex scandal behind Brideshead Revisited - Times Online

Quite a detailed re-telling here of the English aristocratic sex scandal which gave the inspiration for Brideshead Revisited.

This part shows a somewhat relaxed attitude to what was permissible in staff interviews those days:

Boom — as Beauchamp was known, ostensibly because of his foghorn voice — was said to have “exquisite taste in footmen”. His interviewing style was unique. He would pass his hands over their buttocks, making a similar hissing noise to the one made by stable lads when rubbing their horses down. If the young man was handsome and pleasant, the earl would remark: “He’ll do well. Very nice indeed!”

The true life story was much more scandalous than what goes on in Brideshead, though.

That's useful

Israel to blame for Arafat death: Fatah | The Australian

THE ruling faction of the Palestinian Authority has formally blamed Israel for the "assassination" of Yasser Arafat, one of the founders of the Fatah party.

At the party's conference in Bethlehem yesterday, delegates unanimously passed a resolution blaming Israel for Arafat's death and setting up a committee to investigate the death.

Well, that'll help things move forward. Maybe they are just annoyed that a significant part of the world believe the rumours that it was AIDS.

But the Saudi King makes some blunt comments that (except the "criminal enemy" quip) are useful:

Saudi King Abdullah said: "Even if the whole world agreed to the establishment of an independent Palestinian state, with all the needed support and backing, it will not be established as long as the Palestinian house is divided."

And referring to Israel as "the criminal enemy", King Abdullah wrote: "I'll be honest, brothers. The criminal enemy could not over long years of continued aggression have inflicted as much damage to the Palestinian cause as did the Palestinians themselves in a matter of a few months."

Over at Gulf News, there was an opinion column earlier this week (I can no longer see it) which urged Palestinians to make alternative plans for what happens if a two state solution is never achieved. The writer did not give any clue as to what the alternative for the Palestinians might be.

Sad Hollywood news

John Hughes, director of Ferris Bueller's Day Off and writer of Home Alone, dies - Times Online

I mentioned him here last year, and he was only 59. I can't think of anyone from Hollywood who has replaced him as a source of witty entertainment that (nearly always) could be enjoyed by adults, teenagers and younger children together. (It's better to put it that way than to use what has become a semi-derogatory phrase: "family entertainment".)

It's a miracle!

Opinion: Do you believe in miracles? - opinion - New Scientist

I'm still pretty busy, but in the meantime, readers of a philosophical bent can go read the above article about the issue of miracles.

I've only read it quickly, and while it's not as clear as it could be, it seems to make some decent points.

Comet or volcano?

Was there a comet impact in AD 536? Maybe.

Doodling discussion

Playing with a graphics tablet is a lot of fun, but I have some trouble finding the best software to use when wanting to do my somewhat pathetic and rushed attempts at cartoons.

My natural inclination is to go for freeware, but I can't say I have found anything I like much. I've tried Dogwaffle, and it is OK, but sometimes hard to find things easily. (One point I want to make is that, when you are using a stylus to move around the screen, the "left click" or "right click" functions are no where near as natural feeling as when you use a mouse. I therefore find software that requires those to bring down menu options quite annoying. (Although you can just tap the screen sometimes in lieu of a left click.)

I have also tried the free version of Art Rage, but for simple pen or pencil functions, I don't care for it.

The best software I have found is actually Art Dabbler, which came bundled with an old tablet before my current one. I find its interface very natural and easy to use. (You open a "drawer" to find your different tools.)

I also find it makes reproduces very smooth lines - something which Dogwaffle, Painter and and free programs do not always achieve.

Sadly, Art Dabbler was sold to Corel and is no longer available. I do have Corel's Painter Essentials (came with current tablet), but there is a bit of a learning curve involved, and it is just not as easy as I would like. (All I want to do is draw nice lines with a "pen" or "pencil" and be able to colour it easily.)

I am sure this is all very boring for people who have never used a tablet to draw, but if anyone has used freeware with their tablet which they are happy with, please let me know.

Lots of steam

World's Largest Solar Cooking System Installed in India

If poorer countries are going to reduce their CO2, while still cooking food, then systems like this will presumably have a role to play:

India already had the previous world's largest solar-powered cooking system, serving 15,000 pilgrims daily at the Tirumala temple in Andhra Pradesh. But now that one has been been one-upped, Taragana reports. The new system has been installed at the shrine of 19th century saint Sai Baba in Shridi and can feed up to 20,000 people per day:

The system generates some 3,500 kg of steam daily, which replaces on a yearly basis 100,000 kg of cooking gas.

3,500 kg of steam? That's how you measure steam?

Anyhow, it would be interesting to know whether the cost is worthwhile in terms of gas savings.

Turnbull and the amazing, all-knowing Rundle

Turnbull's solid case may fail to rescue credibility

Michelle Grattan in The Age is pretty forgiving in her assessment of Turnbull and the "utegate" affair. As she says:

...most honest journalists would have to admit that, presented with Grech and his document, they would have thought they had a pretty watertight story. Especially given that the evidence points to a long relationship with the Opposition.

The worst commentary on this is from Guy Rundle in Crikey (which is the subject of a LP post here), yet because it is a silly exercise in psychoanalysing all the major players and condemns Turnbull and everyone around him, the people at Larvatus Prodeo think it's great.

I don't begrudge that the leftie readers of LP think that Turnbull has shot himself in the foot in a major way. But what really annoys is that they (and in particular, Mark Bahnisch, who reproduced the article) do not call out the obvious flaws in the Rundle article as a piece of analysis. I mean, really, it starts:

It should have been obvious to anyone who came into contact with him that Godwin Grech was not a man whose robustness could be assumed. Apparently frail and ill from childhood, a solitary type who joined the CPS directly from university, he clearly found in public service a framework for his existence, and a meaning for a life he reasonably assumed would be foreshortened.

He can also tell how meetings he never saw must have gone:

Most people would have spotted instantly that someone like Grech was out of his element, in crisis, that there was a point at which to stop.

And Turnbull's decision to run with the issue:

...contributed to the ruination of a man whose one hope for a meaningful and rounded life, for a life that made sense, was to have been, and been remembered as, a dutiful and effective public servant. Turnbull was the stronger man. It was his fault.

As for Turnbull and Abbott:

Like many of a certain type of Roman Catholic, and Turnbull is the same, Abbott is a man without a soul who outsources its provisioning to the most dependable outfit around — and one that, unlike protestantism or Islam, doesn’t demand that you make much of an effort to change your nature.

You can bet your bottom dollar that Bahnisch, if reading some equivalent armchair psychoanalysis of Labor figures would be calling it as overheated rubbish and pathetic as an exercise of alleged serious political analysis.

The point is, Mark likes to get annoyed about the quality of political journalistic analysis, but only when it is against his side of politics.

Small black holes delayed

Large Hadron Collider Struggles, Adding to the Mysteries of Life - NYTimes.com

The LHC is currently planned to be turned again in November, but its major, major teething problems mean it won't be working at its intended full strength for some time (maybe never):

.....scientists say it could be years, if ever, before the collider runs at full strength, stretching out the time it should take to achieve the collider’s main goals, like producing a particle known as the Higgs boson thought to be responsible for imbuing other elementary particles with mass, or identifying the dark matter that astronomers say makes up 25 percent of the cosmos.

The report goes on to explain the technical nature of the problem, for those interested.
