Aussie fuel cells
On Saturday Extra on Radio National this weekend, they were talking about an Austalian company which is developing them too. There is no transcript available, but you can listen to it on streaming audio here. (It starts about half way through that segment.)
The link to the company itself is here. I don't think it is not mentioned on their site, but was in the interview, that it is CSIRO research which the company is trying to commercialise.
We won't be seeing them anytime soon in Australia, however. According to the interview, they are being commercialised for the European, Japanese and North American markets. This is because the cost of electricity here is such that they are not yet cost effective.

Just what the world has been waiting for...
...robots that make smells:
Pomi (Penguin Robot for Multimodal Interaction) can see, hear, touch and emit smells as well as making faces, Friday's Korea Times reported. It was developed by the state-run Electronics and Telecommunications Research Institute (ETRI) which plans to put Pomi to commercial use. The institute said Pomi's software, which imitates human expressions of emotion, will be available on the market by the end of next month. The robot can move its lips, eyebrows and even pupils freely to make faces and can emit two kinds of fragrances to match its emotions.Let's all pray that the Korean's never design a kimchi eating penguin robot that can "emit" smells.

The strength of a weed
The link is to a story about very thorough sounding research in the US which shows that marijuana is indeed much stronger than it used to be in its THC levels:
I note that it is talking averages too, so presumably a significant amount in use is above that level.The latest analysis from the University of Mississippi's Potency Monitoring Project tracked the average amount of THC, the psychoactive ingredient in marijuana, in samples seized by law enforcement agencies from 1975 through 2007.
It found that the average amount of THC reached 9.6 per cent in 2007, compared with 8.75 per cent the previous year.
The 9.6 per cent level represents more than a doubling of marijuana potency since 1983, when it averaged just under four per cent.
Last year, The Guardian reported that tests in the UK indicated the average there was 14% (with a small number of samples at 20%).
I'm not sure if similar research is done in Australia. Will have to look around some other time.
Analysing Japan
This commentary on the social problems within Japan (viewed in light of the recent Akihabara killings) is spot on.
A key thing that they have to change is the cultural attitude to mental illness and depression. I may have mentioned before, but an Australian friend who lives in Japan (and until recently worked in an administrative position in an english language school) told me that they always did whatever they could to avoid their foreign teachers being taken by police to a psychiatric hospital, because once in there was no telling when they would ever get out. Involuntary admission to a Japan psych ward is something to really fear, apparently.
Even non-psychiatric medicine can expect patients to be stoic to an extent that we haven't seen in the West for many years. A few years ago I was told by a Japanese specialist who performed stomach endoscopies that they were done without any anaesthesia, and as a result were very unpleasant for the patient. (He said he would take a lot of convincing to ever undergo one himself, as he knew how awful they were. I don't know that your gag reflex ever properly stops while you've got a tube down your throat into your stomach.)
As it happens, I had a stomach endoscopy once in Australia in the early 1990's, and knew nothing about it until I woke up. He could not really explain why Japan did not believe in anaesthesia for this procedure. I am sure that he knew that this was not just a peculiarity of the hospital he worked in.
One thing I did not know is that, according to the article, Japan's relatively generous medical insurance schemes do not cover psychiatric treatment.
Amazing, hey?

Real life ocean acidification
Here's a very interesting recent report on some science being done in ocean areas near Italy that already are more acidic due to volcanic CO2 bubbling through the sea.
As expected, the news does not look good for corals, sea urchins, sea snails, and mussels. (I assume that oysters, although they don't get a mention, would also not fare well .) One thing that does well appear to do well is seagrass. I suppose that might mean that one winner out of ocean acidification might be dugong/manatees. I don't know whether they taste any good, though.
Here's the abstract in Nature, but the article itself is behind a paywall. Grrr.
It's also interesting to note the recent stories about the surprising number of bacteria found to be living in the earth's crust under the oceans. The exact role of these in carbon cycling is unknown, but would seem to be potentially very significant. Kind of hard to study bacteria that live best under great pressure, though.
I assume that bottom living bacteria would be very significant to the feared production of poisonous gas if the ocean becomes warm and acidic enough. All a worry.
UPDATE: I hope the tone of my post didn't sound too dismissive of concerns about this.
The Nature paper attracted attention in The Times and The Telegraph. Here's what one of the scientists said in the latter:
Also, I note that, although there was a lengthy Sydney Morning Herald story on ocean acidification on 7 June, it did not mention this paper. In fact, I can't see from Google that it has been reported anywhere in the Australian media. Sort of odd, isn't it, given the implications for the Great Barrier Reef?Dr Hall-Spencer said: "What we saw was very dramatic and shocking.
"All the predictions made in lab experiments about acidity causing the disappearance of species is coming true.
"When we looked in the field it was already happening.
I must admit I though a lot of the claims being made about species disappearing amounted to scaremongering but now I have seen it with my own eyes.
"Our field studies provide a window on the future of the oceans in a high CO2 world. We show the dramatic ecological consequences of ocean acidification including the removal of corals, snails and sea urchins and the proliferation of invasive alien algae."
"Our observations verify concerns, based on laboratory experiments and model predictions, that marine food webs will be severely disrupted and major ecological tipping points are likely if human CO2 emissions continue unabated."
Why Israel must survive...
This Time blog link explains all:
Iranian Prez stars in Israeli TV Ad - The Middle East Blog - TIME
But oddly, one of the comments about the post thinks that the fact that Israel TV carries a parody about Ahmadinejad threatening nuclear destruction means that "it shows how the "threat" from Iran has been so indoctrinated into Israeli culture that it is accepted as common and undisputed fact."
I would have thought the opposite is more likely; if the population really fears immediate destruction, they presumably wouldn't find the ad funny. (That's not to say they don't fear a nuclear threat in the future.)
Anyway, as I am sure I have said before, can those who make excuses for Iran having nuclear weapons ever point to any Israeli leader talking about the imminent disappearance of one of their neighbours?
As for the ad itself, here's the Youtube link.
Stand on the scales, please
This article explains what steps the airlines are taking to try and economise on fuel. Some of it I find hard to believe:
Up in the cockpit, Delta is studying whether it is feasible to divide the heavy pilot manuals required on each flight between the captain and first officer, so pilots are not toting duplicate sets of five or six books that each weigh about a pound and a half.On the other hand if this is true:
“Every 25 pounds we remove, we save $440,000 a year,” Mr. McGraw said...airlines in countries with significant populations of the obese must be really suffering! Why shouldn't airlines be offering cash back offers for passengers under the national average weight if they are willing to stand on the luggage scales before boarding?
UPDATE: at the risk of referring to the Colbert Report just a little too much, he covered this possibility in last night's show (which I saw after my post):
Also on that episode, he had an interview with a guy who has a book out on the 1950's "comic panic" in America. I had referred to this recently when talking about the Dean Martin/Jerry Lewis movie "Artists and Models". If the topic interests you, the interview is both interesting and funny. (You can find it at Colbert Report website yourself.)
A Wednesday compilation
Andrew Bolt has covered well the silliness of giving money to Toyota to do what they were going to anyway. I expect the next question time in Parliament will go on about this at length, and rightly so.
* Crab scam: Also in Japan, the fraud is of a fairly esoteric nature. Read about the great Japanese crab scammers here.
* A new way of saying "when Hell freezes over": "when Tim Blair becomes a hypermiler": Wired has an article about "hypermilers" (being people who have become obsessed with driving in such a way as to get maximum fuel economy from their cars.) Some of the methods are just nuts:
Fulton routinely gets 55 mpg from his 1997 Toyota Paseo, a car the EPA rates at 29 mpg. He started hypermiling about 18 months ago when he landed a new job 37 miles from home and got tired of burning so much gas. He mastered "pulse and glide" -- turning off the engine and coasting while driving. "This technique alone dramatically increased my mileage from 38 mpg to 47 mpg on my first tank," he says. "I was blown away."Well, let's just sit back and wait for the first manslaughter conviction for a hypermiler who couldn't use his power steering to help avoid a deadly collision.
* Indiana Jones and the Green Left Weekly: Just what you were waiting for: a socialist left critique of Indiana Jones! The reviewer complains:
The indigenous people who help Indy in his exploits are sympathetically portrayed, but those who resist are seen as ignorant and superstitious. And some really nasty racism rears its ugly head.That's what I like about the po-faced Left: the way they attempt to crush the simple enjoyment out of life. (It is also analysis like this that made the first Austin Powers movie very funny. You know - the part where suddenly the movie veers into looking at the effect on the bad guys' families after they're killed.)
An audience survey of the most popular scenes in Raiders revealed that most people’s favourite scene was when Indy guns down a sword-wielding Egyptian man with a pistol in a crowded square. What if the situation was reversed and a sword-wielding white man was gunned by an Arab? Would it still be the public’s favourite scene? I don’t think so.

Monday compilation
* How unlucky can you be? To be born albino is pretty unlucky. But to be born albino in certain parts of Africa is taking things to a whole new level. A pretty amazing story in The New York Times explains that albino people s are being killed in sub-Saharan Africa because of magic:
....recently in Tanzania...at least 19 albinos, including children, have been killed and mutilated in the past year, victims of what Tanzanian officials say is a growing criminal trade in albino body parts.Darkest Africa indeed.
Many people in Tanzania — and across Africa, for that matter — believe albinos have magical powers. They stand out, often the lone white face in a black crowd, a result of a genetic condition that impairs normal skin pigmentation and strikes about 1 in 3,000 people here. Tanzanian officials say witch doctors are now marketing albino skin, bones and hair as ingredients in potions that are promised to make people rich....
In early May, Vumilia Makoye, 17, was eating dinner with her family in their hut in western Tanzania when two men showed up with long knives....
When Vumilia’s mother, Jeme, saw the men with knives, she tried to barricade the door of their hut. But the men overpowered her and burst in.“They cut my daughter quickly,” she said, making hacking motions with her hands.
The men sawed off Vumilia’s legs above the knee and ran away with the stumps. Vumilia died.
* God gets challenged again: Theodicy gets another discussion in this book review in the New Yorker. Interesting, even if nothing especially new in it.
* I always wanted to live in a dome: It turns out that Buckminster Fuller, famed for coming up with the geodesic dome (and some much sillier designs for all sorts of stuff) was quite the eccentric. Read all about him in a very entertaining article in the New Yorker. Here are some of my favourite sections:
With no job and a new baby to support, Fuller became depressed. One day, he was walking by Lake Michigan, thinking about, in his words, “Buckminster Fuller—life or death,” when he found himself suspended several feet above the ground, surrounded by sparkling light. Time seemed to stand still, and a voice spoke to him. “You do not have the right to eliminate yourself,” it said. “You do not belong to you. You belong to Universe.”...One idea that he came up with was for the "Dymaxion Bathroom—a single unit that came with a built-in tub, toilet, and sink". In fact, I believe this how bathrooms for apartments for Japan are made. Japanese bathing style requires that the entire small bathroom can get wet, so for apartments they are like sealed plastic units that come prefabricated to incorporate into the building.
Castro-like, Fuller could lecture for ten hours at a stretch. (A friend of mine who took an architecture course from Fuller at Yale recalls that classes lasted from nine o’clock in the morning until five in the evening, and that Fuller talked basically the entire time.) Audiences were enraptured and also, it seems, mystified. “It was great! What did he say?” became the standard joke....
Fuller championed, and for many years adhered to, a dietary regimen that consisted exclusively of prunes, tea, steak, and Jell-O. (!!!!!!)
Once you read the article, have a look at the slide show taken from an exhibition that inspired the New Yorker article.
* Justifying affairs: Across the Atlantic, and Zoe Williams in The Guardian takes a sarcastic look at a book entitled "When Good People Have Affairs". Her favourite of the 17 motivations listed therein: breaking out into selfhood.
On Colbert Report tonight, there's a slightly amusing interview with an writer who has also written about why people have affairs. I suspect that (towards the end) Colbert's personal conservative-ish views are on display here (which is fine by me, of course):
* Books for husbands to buy their wives: Back to the New York Times, and there's a review of two books by couples who tried to help their marriages by having sex every day. What's not to like about that idea?
How to annoy the neighbours
The Australian media is widely reporting today that our PM Rudd is the "first serving Western leader" to visit Hiroshima.
I had my doubts this was true. In fact it only took a visit to Wikipedia to show it's wrong. New Zealand PM Helen Clark was at the Peace Memorial Museum in 2001, as the link above shows.
I think the mis-reporting may be due to Rudd being the first to visit a certain part of the memorial.
So sorry about that, Helen.
Blogging slowdown
The record sales area there is a sight to behold, with lots and lots of vinyl LPs from my younger years to be found. My wife actually got some classical music LPs, which meant I spent some time turning them into CD's for the rest of the weekend. I got to hear most of Aida that way. It's mostly dull, I've decided.
The family also saw Prince Caspian yesterday. I will do a separate post about it sometime soon.
But generally this week, posting will be lighter than normal. I need money, as does the tax office, and as much as I enjoy posting intermittently all day, I really have to stop that habit.
(Of course, my invitation to mad benefactors is still open. I would mention you very favourably!)

Aboriginal issues revisited
Go the link for a disturbing story of apparent cultural norms in remote aboriginal communities in the Northern Territory. Short version: an Aboriginal community officer accepted his 13 year old daughter sleeping with a 20 year old bloke, who has since gone to jail.
The officer (who the newspaper calls a police officer, so I take it that is technically correct) will just face some internal discipline. As for the poor daughter:
The court heard the girl had contracted three sexually transmitted infections and that her baby had died in-utero.What I also find irritating about the story is this statement by the NT Police deputy commissioner:
"Following the Chief Justice's comments that Aboriginal leaders in communities should demonstrate leadership to prevent the practice of tribal marriages to underage girls, the Northern Territory police are developing an internal information package to assist not only Aboriginal community police officers, but police generally in this regard,'' he said.As I said back in June last year, what exactly is the insurmountable difficulty that any government has in making sure that aboriginal communities know a few basic laws? As I said then:
....this is an area where I think most people should rightly react along the lines: "forget cultural sensitivities when it comes to knowing what is child (or even adult) sexual abuse. They just need to be told in English (or if they don't understand that, their own language) a few key points: incest is illegal at whatever age; sex between adults and children is illegal. Sex without consent is always illegal too, no matter what age. No one who has an STD should have sex with anyone until it's cured. "Meanwhile, I've had some interesting talk with my relatives in Far North Queensland about how things are going in the Aurukun/Weipa area. The tavern at Aurukun now apparently only sells light beer, and this has not gone over well. Grog is smuggled in both overland and via boats. The police search vehicles driving into the township regularly, but grog is dumped in the bush for later retrieval when the residents can see that the polices cars are all back at the station. It is also smuggled in by boats (operated by aborigines, not whites.)
The basic rules just aren't all that complicated, surely.
Meanwhile, I am told that Weipa is now not safe to walk around at night. The places that sell alcohol at Weipa cannot refuse to sell to aborigines, and in fact much of the alcohol that ends up in Aurunkun comes from there.
What a nightmare.

Jews out of Egypt
Interesting story about Jews who were "exiled" out of Egypt since the creation of Israel:
In 1948, around 100,000 Jews lived in Egypt, but by 2007 that number had dropped to between 20 and 100.Some Jewish groups have sought documents from Egypt relating to the history of the former Jewish residents:
However, Egypt has refused to release the documents to the historical society. Sakkal said this was a consequence of the Egyptians' fear of restitution claims.The Egyptian government is just a little sensitive about the issue:
On May 10, Egyptian Culture Minister Farouk Hosni said during a parliamentary conference that he "would burn Israeli books myself if found in Egyptian libraries."
On Obama
But I have some impressions about Obama that I may as well share now:
1. There's a certain touch of the Kevin Rudd's about him. Lots of talk about symbolism and changing paths, etc; but pretty empty with clear, concrete policy when you come down to it. It's all to be worked out in the future.
2. Am I the only person who thinks that his political success is about 50% attributable to his voice alone?
3. Some things that raise doubts about his general wisdom: that church, and he was/is a smoker. (Yeah, sorry, but a guy with a family in his forties who still smokes is showing reduced common sense. Tough but true!)
4. His wife looks a little mean to me.
5. I worry that he will be another Jimmy Carter: all well intentioned, but weak when it comes to dealing with difficult nations.
6. He is really going to galvanise the pro-lifers in the campaign if this statement from this article from American Spectator is correct:
And he promises, "the first thing I'd do as president is sign the Freedom of Choice Act," which would over-turn hundreds of federal and state laws limiting abortion, including the federal ban on partial-birth abortion and bans on public funding of abortion.7. Apart from youth, the comparisons with John F Kennedy are somewhat off the mark. At least Kennedy had both distinctive military service and 14 years as a federal politician behind him. (Actually, I didn't realise JFK had been in politics for so long before he became President.) That crack that Hilary Clinton made about her experience versus Obama's "one speech" certainly rings very true.
UPDATE:
8. Great gaffe made by Obama about Jerusalem this week. He's really got the trainer wheels on. (How Bush would be slammed by the Democrats if he had said the same thing.)
Looks fun
While you are busy ignoring my warnings of ocean-led environmental catastrophe, it looks like you could do worse than take the kids to go see Kung Fu Panda. (Or just take yourself anyway.)
I saw the shorts at Indiana Jones, and thought it looked "nothing special". But the initial reviews from the States (see link above) are generally very positive.
Ocean acidification, continued
From this very short report:
Meanwhile, the Hobart Mercury reported recently about a conference there:CSIRO marine scientists say the Intergovernmental Panel on Climate Change and scientists worldwide are neglecting the earth's oceans in researching the effects of climate change.
In an article published today in the journal Science, the researchers argue that the effects of climate change on oceans is being underestimated.
CSIRO marine scientist Bronte Tilbrook said what was already known about ocean acidification was troubling.And earlier in the report:
"Indications are that we will see some fairly significant changes in the ecosystem," Dr Tilbrook said.
"Under the CO2 emissions scenarios -- and it's the high ones we seem to be tracking at present -- in about 2060 we'll cross a chemical threshold in the Southern Ocean where one form of calcium carbonate will become chemically unstable.
"It's very early days to say there will be a decline in (fishery) production or an increase -- some species will do better, we just don't know if they're going to be of much value for the ecosystem."
The gathering of some of the region's leading climate change experts was told oceans would reach a carbon saturation tipping point within 50 years and nobody knew what might happen then.Now, as the article makes clear, these problems are going to happen regardless of successful cuts in current CO2, because of the time it takes for the ocean to absorb CO2. So, you could argue that there is not much point in worrying now anyway.
But, go back to my original posts about this for my argument as to why we shouldn't let CO2 creep up towards 1000 ppm.
Pay attention, people.
Unkind cuts
This article speculates on why circumcision (and more drastic forms of cuts around the genital area) developed at all.
While I had heard about subincision before, I didn't know about crushing a testicle:
In some African and Micronesian cultures, young men have one of their testicles crushed.And you thought public circumcision would be something to fear as a 12 year old!
Anyway, the article argues that this is all to do with reducing the risk of younger men impregnating older men's wives. This is particularly the case in polygamous societies:
Sounds plausible, but caution is always advised in such matters of evolutionary biology.The older men have also gone through the ritual, and seen their own reproductive effectiveness reduced. But if a man with, say, four wives wants to ensure that any children his wives produce are his, there is pressure to make sure other men can't successfully impregnate them.
The husband's own reproductive ability is impaired, but continuous and repeated access to his wives makes up for it, while any genital mutilation is a greater handicap to an interloper trying to sneak brief occasional sex with his wives.
(Incidentally, in the all the guff that anti-circumcision groups go on with, do they ever take into account a preference that women may have for circumcised men? As this article indicates, I would assume that circumcised young men have more of an issue with premature ejaculation, which women don't exactly welcome.)
Me, me, me
Well, it's sort of fun to watch the emotionally needy Paul Keating say "it was me, me, me" again. He does go on about "lost years" of Howard government diplomacy, doesn't he? What exactly does he think Australia could be doing differently in China or Indonesia now if his great and glorious leadership had continued?
Anyhow, it's good to see Labor people being skeptical of any burst of symbolism from Rudd.
Speaking of needy personalties, as if you didn't know, we can add Richard Woolcott to the list:
....the Herald learnt that Mr Rudd's special envoy for the project, the former diplomat Richard Woolcott, found out about the proposal only two hours before it was announced on Wednesday night.Can't he just develop an interest in fishing, or something?
Prat
So, The Age gives us a review of Prince Caspian which is purely based on Philip Pullman-like ideological hatred of CS Lewis. Have a look at this line:
Sometimes critics are accused of reading sinister messages into works of harmless entertainment but that won't wash in the case of Lewis - a fierce polemicist who used fantasy as a platform to rail against everything he disliked in the modern world, including democracy, lipstick and progressive education.I wouldn't mind betting that Wilson, the author of that "review", is a youngster atheist who has never read Lewis.
You can safely assume that Wilson is on his own planet here: both Margaret Pomeranz and David Stratton gave it respectful reviews, and they are both liberal lefties who are uneasy about Christian stuff. (Oh, while you are at At the Movies, you should read the conflicting reviews of Sex and the City. It's pretty funny.)
I'll be off to see this weekend. Then I should go wave protest placards in front of Sex and the City.
Tim Train: I expect you to attend this weekend too. And you had better like it!
