Questionable side effects?

I had a quick read of Dr Kerryn Phelps's (relatively) well publicised submission to the parliamentary health committee's inquiry into long Covid, and I don't know, but it felt - kind of fishy.  

As everyone knows, she was no anti-vaxxer when Covid started, and the first 7 pages of her submission are really spent justifying her warnings early on about the danger Covid (and long Covid) generally.

It's when she starts talking about the damage vaccination caused her and her wife that it starts sounding  questionable.  First, it's pretty surprising that both of them should have adverse effects.   And secondly, despite her talking about all of the specialists who have confirmed a real problem with both of them, I would like to hear more directly from specialists than from her:

I have had CT pulmonary angiogram, ECG, blood tests, cardiac echogram, transthoracic
cardiac stress echo, Holter monitor, blood pressure monitoring and autonomic testing.  In my case the injury resulted in dysautonomia with intermittent fevers and cardiovascular implications including breathlessness, inappropriate sinus tachycardia and blood pressure fluctuations.

These reactions were reported to the TGA at the time, but never followed up. 

I have spoken with other doctors who have themselves experienced a serious and persistent
adverse event including cardiological, rheumatological, autoimmune reactions and
neurological consequences. Patients and other members of the community have told me
about their stories.

They have had to search for answers, find GPs and specialists who are interested and able to help them, spend large amounts of money on medical investigations, isolate from friends
and family, reduce work hours, lose work if they are required to attend in person and avoid
social and cultural events.

Look, this is really just my gut reaction, but there is a reliance on anecdote to bolster her argument  (and from people who sound like they have a "no one will listen to me" sort of semi-conspiracy mindset) which feels like there are some psychological issues drawn into this.   

On the other hand, it's true - I did find myself having some bursts of high blood pressure readings for the first time in my life during this year (they seem to have stopped or reduced now, and I suspected some work stress which has lessened now has helped with that.)    I did wonder whether Covid vaccination had any connection with it, and I posted before that some studies indicated that there could be.   

But I just get the feeling that with Phelps and her partner, it's more complicated than a direct vaccine side effect.

The weed that will remain un-named?

I have been curious to know more about how harvesting a bit of weed with your spinach could result is hallucinations and other ill health.   I see there was a bit more commentary on this yesterday, and I get the feeling that even if the weed is clearly identified, the authorities doubt it is a good idea to publicise it:

Australians are being urged not to seek out contaminated baby spinach products for a recreational high after more than 130 people who ate a range of fresh food items suffered symptoms including hallucinations and delirium.

Authorities were on Sunday night testing the weed believed to be responsible for the widespread recall of products containing spinach thought to have come from a farm in Victoria....

Symptoms can be severe and include delirium or confusion, hallucinations, dilated pupils, rapid heartbeat, flushed face, blurred vision, dry mouth and skin, and fever....

Dr Brett Summerell, chief scientist at Sydney’s Royal Botanic Gardens, said it was hard to distinguish between many plant species when they were small. He suspected toxic plants including nightshades could be to blame.

“There are lots of plants that could do this – lots of weeds that are relatives to potato and tomato,” he said.

“This is likely to be a nightshade. When young, they are just a few dark green leaves which is probably not that much different to spinach. You’re harvesting all these leafy greens now at a very young age, sometimes it can be quite difficult [to identify].”

Summerell said farmers were facing the extra challenge of an explosion of weeds right across the country after months of rain and floods....

Summerell warned people not to go searching for the contaminated products or pick and eat weeds they could not identify in search of a cheap high.

“People might be tempted to go out picking weeds thinking that they’ll get some sort of high [but] it’s really important to remember yes, there might be a hallucinogenic side to this, but there’s a whole lot of really horrible health issues,” he said.

Update:  well, that took a while, but it has been named:  thornapple.  Never heard of it, and kind of surprising that this is the first time it has happened.   

 

A direct line from God

I don't know why this crossed my mind recently - oh yeah, I do remember now, but the story is too long to relate here - but I thought "Isn't it odd that generally speaking, it seems Muslims faith does not involve the idea of God ever 'talking' directly into the mind of the believer, it's more about listening to what God wants as teachings mediated via your Imam.  Christians, on the other hand, and especially fundamentalist (and American) Christians, are all about thinking that God is causing them directly to think or feel something in their head.  One would think that the latter might be potentially more dangerous for society, and the Christian Nationalism movement in the US is full of highly armed people who seem to want to fantasise about killing the evil for God; but on the other hand, Muslim terrorist attacks have obviously been a thing.  It's a bit complicated..."

On the issue of "does God talk directly to believers", I thought I would Google it, and came up with this rather handy column from (of all places) the Reno Gazette Journal, which quotes people pretty much confirming my understanding:

Sherif A. Elfass, Northern Nevada Muslim Community president

In Islam, the means of communication that can take place between God and human beings are described by God in the Quran: “And it is not for any human being that Allah should speak to him except by revelation or from behind a partition or that He sends a messenger to reveal, by His permission, what He wills. Indeed, He is Most High and Wise.” (42:51).  Islam teaches us Allah (SWT) spoke directly to Prophets Adam, Moses and Muhammad (PBUT) only without ever revealing Himself (from behind a partition). Allah (SWT) spoke to some of the prophets, like Prophet Ibrahim (PBUH), through revelation that came as dreams. However, the most common method Allah (SWT) used to communicate to His prophets is through angels sent as messengers. Since no prophets will come after Prophet Muhammad (PBUH), the communication between Allah (SWT) and human beings is limited to revelations through dreams.

As for one of the Christians represented in the column, he's a bit cautious:

Steve Bond, lead pastor, Summit Christian Church, Sparks

Yes … God speaks directly to humans. Over 2,000 times in the Old Testament there are phrases such as, "And God spoke to Moses" or "the word of the Lord came to Jonah" or "God said."  We see an example of this in Jeremiah 1:9. "The LORD reached out his hand and touched my mouth and said to me, 'Now I have put my words in your mouth.'" Jeremiah claims to speak specific words God had put into his mouth.

During the birth of Jesus, God spoke to Mary through an angel; he spoke to Joseph through a dream; he spoke to the shepherds through an angel and he spoke to the Magi through a dream. Yes, God speaks!

But now that the Scriptures are complete, any word from God must be corroborated by the Bible. God’s Word is the plumb-line against which all new revelation is measured.

In fact the Catholic representative sounds a bit more into affirming the direct line from God to the brain:

Monique Jacobs, director of faith formation, Roman Catholic Diocese of Reno

God has a long history of speaking directly to humans. In Scripture — Old and New Testaments — you will see God has made it a priority to communicate directly with us over the centuries. If you love someone, you find every opportunity to communicate — it’s no different for God. Though you may not have experienced this (yet) God doesn’t reserve this loving, intimate conversation for saints alone. There is a lot of competition in our lives for the voice of God; the trick is to make time for quiet: intervals of solitude, hiking or running without earphones, sitting beside a candle trusting your presence is enough. Breathe. God is patient, so must we be. We cannot make these encounters happen by willpower; it is all God’s initiative — our part is the response. Our heart should be open, expectant; don’t worry about “doing it” right or imagining the whisper.

The Buddhist rep sounds a bit trippy:

Matthew T. Fisher, Reno Buddhist Center resident priest

Buddhism is a non-theistic world view, so this is not a central question. But we can ask if the Light of the universe can be heard? After the Buddha was enlightened he described a vibrant scene — more beautiful than any he had ever seen. He called this “being awake,” deeply hearing the world around him. All sentient beings can reach this state, but we are limited by biases and narrow habits of thought. This deep hearing of the light is joyous appreciation of the wondrous gifts the universe offers. Does the universe talk? Only if we listen.

Conversations do happen. Just after the Buddha was enlightened, the highest of Hindu gods, Brahma, encouraged Buddha to go forth and teach. Though Buddha was reluctant, he was swayed by Brahma’s request. And sutras recount many gods listening with interest to the Buddha’s important discourses like the Lotus Sutra.

Just wait until Elon Musk gets to put in brain implants:  maybe that will increase the efficiency of communication...

      


A short video on (Chinese) language

Yes, it's from CGTN, so naturally it's going to be here only to show something positive about China, but I had never thought of the benefits of their type of written language before, so here we go:

Things I didn't know about Chesterton

I've never read much about GK Chesterton:  I did start one of his Christian apologetics books once but gave up, finding the writing style too much hard work.   (From memory, it was a bit like Joseph Conrad writing non-fiction.)   

There's a long review of a book about him here which makes me glad I haven't bothered too much about his biographic details, as his life seems to have involved an awful lot of political intrigue which seems rather arcane from this distance in time.  (By which I mean, you have to have a pretty detailed understanding of early 20th century British politics to follow it fully.)  

Anyway, I did learn a few things which are odd and noteworthy:

Sex was not an obvious temptation either. Despite the restrictions she put on his wallet and on his waistline, G.K. adored his sober, dutiful, unshowy Frances, and was content to be mothered in his incompetence. But no children came, and Chesterton’s sister-in-law, Ada – she married his younger brother, Cecil – later claimed the wedding night had been so ghastly for Frances that their marriage had remained sexless. This might not be true: Ada had long nursed a grudge against Frances for taking G.K. out of the sharp-witted, boastful and heavy-drinking coterie of Fleet Street pals, where she had met the Chestertons, and off to sober Beaconsfield. 

[To be fair:  I see from a paper written for the Australian Chesterton Society, that there is this apparent explanation for their childlessness: 

The first eight years of their marriage they tried to conceive. Frances underwent an operation. Then a second. Then a third. There are no medical records as far as what exactly these operations were. After the third, the doctor sadly informed Gilbert and Frances that it was unlikely they would have any biological children.
The source for that is not given, however.]

He had a younger brother, Cecil, who apparently was a very unlikeable fellow:

Ada, writing in 1941, leaves this without comment, as ungainsayable evidence that Cecil was ‘the most brilliant debater of his time’. As a child, she adds, he kept pet cockroaches and stacks of copybooks ‘containing juvenile novels and political theses and economic systems – the outlines of a Cecilian form of government, which covered every phase of national life’.

Unpopular at school, Cecil would monopolise conversations with his ‘contradictory temperament and an extraordinary belief in his own ability’, his fellow journalist Frank Harris remembered. It could not have been easy being the little brother of someone so famous and well-loved, but Cecil was convinced he’d been overlooked: Leonard Woolf noted the streak of ‘fanatical intolerance’ nourished by a ‘grudge against the universe, the world and you in particular’.

I didn't realise he only became a Catholic in 1922, at the age of 48.  He died aged 62.   

Also, and this is not from the book review, but Wikipedia:  I knew he was rotund, but didn't realise he was also extremely tall:  6 foot 4.  

An odd character all around.


It's all making sense now


 (As you can see, I'm still visiting Twitter, but it is definitely starting to empty out of people I like.)

The rise of Mastodon?

I went and tried Mastodon in Android App form.

A few observations:

a.    creating an account is not hard, and I think it's a bit ridiculous that so many people are complaining that the basic way it operates is so confusing.   Gee, how much does it take to Google up any number of various guides as to how it works? 

b.    I don't know why more journalists I follow are not already on there, and putting their mastodon address on their twitter profile.   It is currently not necessarily easy to find people via search.

c.    This, in my short, less than 24 hours, experience is the biggest problem with it as a Twitter substitute - the search function seems very wonky compared to that of the blue bird.   Is it always going to be like that, because of the distributed server aspect of it?   

But look, overall, it seems to me to have potential.

"Twitter is my toy now and I chose who to share it with"

 It just occurred to me that Elon Musk is now running Twitter pretty much like how Sinclair Davidson ran his (alleged) exercise in "free speech" (the old defunct Catallaxy blog):  they both claim to defend it [free speech], but not to the extent that you can freely rubbish them or their special friends without knowing when the arbitrary  hammer would strike to ban or restrict someone just for annoying them.    

Musk's behaviour is increasingly erratic and petty:  and by the way, if the richest man in the world can't afford a good security minder for him and his family, who can?    It seems a significant number of people I like to follow have left Twitter now, as hanging around to be treated by the owner like you're a mere cat toy is degrading.

It has reached the stage that I have to investigate Mastodon.    Not that I post tweets, but yes, there really needs to be a general strike against using the site.

Fusion issues - when does an exaggeration become deception? [And cringe, but I cite Elon Musk in support!]

I'm a bit surprised, but Sabine Hossenfelder seems to not want to give any encouragement to fusion power skepticism after the "net energy gain" breakthrough announcement from Lawrence Liverpool this week.  

And look, I know that I criticise amateur "armchair experts" on matters like climate change and vaccines, so I feel I am at great risk of being called a hypocrite when I now put my own version of amateur assessment on this topic.  

But, but:  I reckon anyone just has to read a bit more widely to understand that the problem is not just getting fusion to work - it's getting it to ever work in a way that makes economic sense for power generation.  I reckon that it's that aspect which no one is asking the pro-fusion researchers to properly discuss and justify. (Sure, the timeframe question comes up - more on that below - but I reckon there is plenty of reason to doubt that it will ever be economically viable.)

I mean (ugh, I know I shouldn't do this appeal to gut reaction, because it feels so much like the same tactics climate "skeptics" use) but look at this photo:


Does this look even vaguely like an easily deployable system for power generation?   It's the National Ignition Facility at Lawrence Livermore where they made the breakthrough, and of course, it just an experimental set up and it was never meant to be something that would generate useful power.  But still, a picture gives an idea of the complexity of this type of fusion set up, so I'm still running with it. 

And when you read about the set up, it almost seems that the question should be "how come it took so long to even get to the net energy gain"?  

‘Nif is the world’s largest, most energetic laser,’ she explains. ‘It’s 192 separate lasers, each one of which is close to the most energetic in the world. And it’s housed in a building that’s three American football fields wide and 10 storeys tall, which is needed for all the amplifying objects. In fact, it’s the world’s largest optical instrument.’ When it fires, the facility’s beams are amplified by 3070 sheets of phosphate glass doped with neodymium, each weighing 42kg and set at Brewster’s angle, which reduces reflective loss. ‘The idea is we take all of that energy, which comes to about 1.9 megajoules, and focus it down on a target the size of a small ball bearing, about 2mm in diameter.’

As for how long they have been trying to get it to make net energy (and only considering the laser power going in, not the energy needed to make the lasers) Science magazine explains:

The $3.5 billion NIF began its “ignition” campaign in 2010.  ...That self-sustaining burn is what defines ignition, and after more than a decade of effort NIF scientists declared they had achieved that milestone after a shot in August 2021 produced 70% of the input laser energy. But NIF’s funder, DOE’s National Nuclear Security Administration, set NIF’s goal as an energy gain greater than one—the threshold it passed last week.

So, $3.5 billion and 12 years to get a single event in which the energy of the reaction was about "the equivalent of about three sticks of dynamite."  A small energy return on investment, if ever there were one.

The Science article does go on to explain a possible future direction for laser fusion (my bold):

The NIF scheme has another inefficiency, Betti says. It relies on “indirect drive,” in which the laser blasts the gold can to generate the x-rays that actually spark fusion. Only about 1% of the laser energy gets into the fuel, he says. He favors “direct drive,” an approach pursued by his lab, where laser beams fire directly onto a fuel capsule and deposit 5% of their energy. But DOE has never funded a program to develop inertial fusion for power generation. In 2020, the agency’s Fusion Energy Sciences Advisory Committee recommended it should, in a report co-authored by Betti and White. “We need a new paradigm,” Betti says, but “there is no clear path how to do it.”

Now that NIF has cracked the nut, researchers hope laser fusion will gain credibility and more funding may flow. 
[Betti, by the way, is from another research lab.]

About that funding - as everyone who has read anything about this knows, a lot more money is going into tokamak fusion research, in the form of the gigantic and hugely expensive ITER plant being built in France:

However, the leading tokamak device, the ITER reactor under construction in France, is anything but simple. It is vastly over budget, long overdue, and will not reach breakeven until the late 2030s at the earliest. With NIF’s new success, proponents of such laser-based “inertial fusion energy” will be pushing for funding to see whether they can compete with the tokamaks.

As for the cost - it seems a matter of much dispute as to how to actually cost it, which is a little odd, but the range (shared by many nations) seems to be from $22 billion to $65 billion.

All that money for possible breakeven by the late 2030's.

Also, the article I first linked to in this post is from Chemistry World, which explains one of the fundamental issues on the economic development of fusion power - the development of suitable materials needed around a fusion reactor:

The greatest problem faced in fusion isn’t achieving the incredible temperatures required – it’s the materials science required to maintain that environment long-term. It’s why Jet couldn’t go past a few seconds, explains Rimini. ‘Jet is based on fairly old copper coils for the magnetic fields, and the tokamak walls are not actively water-cooled, so the high fusion period is only designed to run for 10–15 seconds at most.’

UKAEA has built a new materials research facility at Culham Science Centre to tackle such problems. One of the staff searching for solutions is Greg Bailey, a computational nuclear physicist. ‘The copper magnets get too hot,’ he says. ‘So, in the future, we’re using superconducting magnets. And hopefully we’ll learn more.’ These material changes have already happened in the past. ‘Jet actually changed the material of its walls,’ Bailey says. ‘Initially we’d made the walls out of carbon, because that made life easier for the experiments. It should have been perfect, but, actually, it was terrible! We were getting a lot of tritium retention – we were losing our fuel into the wall, the hydrogen was drifting inside. So we had to change it.’

The design challenges discovered and solved by Jet are already being fed into Iter, explains Bailey. ‘What does a material for a reactor need to be? Resistant to damage [from radiation], it needs to be able to take the temperatures and extreme environments, and maintain its mechanical properties during its lifetime. So, in terms of a fusion reactor, the vast majority is probably going to be steel. The really interesting bits come inside the vacuum vessels, your housing, because they’re going to be facing extremes. They need armour, obviously.’

This has resulted in plans for Iter to be covered by 440 ‘blanket’ modules, weighing up to 4.6 tonnes, which cover the steel of the tokamak’s structure. Neutrons discharged during the reaction the enter the blanket can be slowed, and their kinetic energy transferred to a coolant system for another form of power. It’s hoped the blanket can also be used to solve another issue for reactors: their feedstock.

‘There’s plenty of deuterium on Earth,’ Bailey says, ‘but deuterium fusion produces much lower energy neutrons; it’s not really a viable source to make a power plant. And tritium is not naturally occurring.’ To obtain their tritium, the team plans to use lithium with an enhanced level of lithium-6, which can break apart under neutron irradiation to produce tritium. Although this is naturally occurring, the problem is that lithium is already in high demand for its use in lithium-ion batteries. ‘Frankly, when lithium comes into our reactor, we’re going to destroy it,’ Bailey says. ‘The fuel is not the problem; it’s how you produce it.’

This is where the blanket could come in, explains Bailey. ‘A lot of designs right now are mixing lithium with lead, or lithium with ceramic and some beryllium in there. The idea is that you get deuterium and tritium, the fusion reactor turns on, and neutrons produced in the fusion reactions smash into the blanket and tritium breeding reactions can occur. We can then extract that tritium to refuel the reactor. And, obviously, the neutron radiation into the blanket will cause a huge amount of heating.’ It’s still not perfected yet, but Bailey is confident the experiments done at Culham will show the way, potentially in collaboration with the private sector; fusion is already attracting major investors, including Amazon’s multibillionaire founder Jeff Bezos. ‘If we want to do fusion on an industrial scale we need to start building that supply chain now,’ says Rimini. ‘We need to start evolving the industry.’

Obvious questions I have:  how long will the "blanket" modules last?   How long will a fusion power plant need to be down while they are replaced?   At 4.6 tonnes each, and presumably all getting radioactive at the same rate - it's going to be a huge maintenance job, and it's something they are only now trying to work out. 

There's a complicated 2017 paper here about the materials science challenges for testing and developing suitable materials:

This paper presents a preliminary evaluation of the materials challenges presented by the
conceptual design [1] for a Fusion Nuclear Science Facility (FNSF) to bridge the development gap between ITER and a demonstration power plant (DEMO). Here the FNSF specifically denotes the concept that has been studied in the recent Fusion Energy System Studies (FESS) supported by the US Department of Energy, also called the FESS–FNSF, which is examining a  conventional aspect ratio tokamak. The FNSF is an experimental machine designed to establish the reliable performance of the critical fusion system technologies required in DEMO and power plants. The FNSF horizontal maintenance system [2] allows for periodic removal, examination, and replacement of full power core sectors.
As far as I can tell, this Facility does not exist yet, and won't for some time.   This presentation from 2014 seems to indicate that it wouldn't really get going until ITER is up and running - in the 2030's - and the 2017 paper says this:

A minimum 20-year timeframe will be required to accommodate the development of the advanced materials to commercialization and code qualification, development of blanket fabrication technologies, evaluation in non-nuclear integrated test programs, and 14 MeV neutron testing in DONES/A-FNS/IFMIF to validate irradiation performance.
So piecing this together, we're getting the "best hope" for tokamak fusion not likely getting to break even until the late 2030's, during which decade a materials research stage which will take a minimum of 20 years will have started.   

Does this sound like commercialisation of fusion power within 20 years?   No it doesn't - sounds more like 40 to 50 - if it is possible at all.  Because isn't this complicated materials science issue likely to be a key one in the question of whether fusion will ever be economically viable?  And we won't even know the answer to that for another 20 to 30 years.

AND YET:   this morning on Radio National, we heard Kim Budil, the director of Lawrence Livermore National Laboratory (home of the "breakthrough") say this at the 12.40 mark:

"So not 50 years away anymore, I would say probably 2 decades of concerted effort and it's plausible we have power plants in development"

To her credit, Patricia Karvelis, sounds skeptical "Wow - really - in 2 decades?"

And Ma says "I think so"

I'm sorry, but ever allowing for the qualifiers of "probably" and "plausible", I reckon that that answer is so practically unrealistic as to be deceptive.  

I'll come back and add a bit more to this post later...

Update:   I had a look at Youtube videos about it, and quickly found one in which a former Secretary of Energy (and nuclear physicist) makes an outlandish claim the he "think[s] we can demonstrate and maybe initially deploy some power plants on the grid within the next decade or so".  [!]

Gee, if anyone invests money in the company he's on the board of, based on this type of spruiking, I reckon it would come close to fraud:

 

More realistically (much, much more realistically) we have an actual former fusion scientist who thinks it's worth pursuing, but he explains in this video from a year ago the huge engineering issues yet to be overcome.  He says there is no way we will have fusion by 2040, and everything I have listed above indicates that is correct: 

 

Finally, and I didn't see this coming or realise it until now, but I'm on the side of Elon Musk!  Here's a short clip in which he says that sure, fusion will be achievable, but it's just not going to be economically viable as a power source, citing the tritium issue mainly.   [I can't embed it, as it's a Youtube short.]   

How embarrassing is that, given that he seems to have driven himself nuts by blowing many billions on Twitter?  Quite - but hey, if the facts are actually on his side on this issue, so be it.

 

What attention are wingnuts (and certain journalists and billionairies) giving to their Paul Pelosi conspiracy being blown away?

The New York Times reports:

It was as quick as it was brutal — captured in just a few seconds of grainy video from a police body camera. Arriving at the home of House Speaker Nancy Pelosi, two officers find an intruder and Ms. Pelosi’s husband, Paul, standing calmly, each with a hand on a hammer that the police demand they drop. Just then, the video shows, the intruder takes control, wields the weapon over his head and slams it with full force.

“Mr. Pelosi was face down on the ground, a pool of blood by his head,” said Kyle Cagney, one of the two San Francisco police officers who were first to arrive in the early hours of Oct. 28, during a court hearing on Wednesday.

As for the mangled initial reporting that Pelosi knew the name of his attacker:

The hearing began with prosecutors playing a recording of a call that Mr. Pelosi made to 911 shortly after the intruder woke him up. During the call, Mr. Pelosi speaks calmly but emphatically, seemingly trying to convey to the operator that he is in danger but without alarming the intruder threatening his life.

Mr. Pelosi said on the call that there was “a gentleman here waiting for my wife to come back.” He told the operator who his wife was, and at one point the intruder in the background could be heard saying, “The name is David.”


Chait on transgender reporting

I see nothing at all to disagree with in Jonathan Chait's column in New York Magazine, complaining about the progressives' debate tactics when it comes to the issue of transgender treatment of children/young adults.   

And it's disappointing when someone like David Roberts, who is sensible on most things, joins in with a snide attack on the bona fides of Chait.

Hoping for a save

It would appear that the screen testing rumours for Indiana Jones 5 (people hated the ending) are probably true?  John Williams said there is a new ending being filmed.

I'm not 100% sure, but I think some famous films (or at least a couple) have been "saved" by a late change to the ending?   

And it still means that I get to hope this happens:

END INDIANA JONES BY SHOWING HIM GOING ON BOARD THE MOTHERSHIP AT THE END OF CLOSE ENCOUNTERS.

 

Pretty good reason to believe this means we'll never hear from him again

RMIT really seems to operate as a sheltered workshop for IPA types.  I was amused to read this on Crikey a day or two ago, in an article about what some recent ex-politicians are doing now:

Tim Wilson

Following his loss in Goldstein to Zoe Daniel, Wilson did the only appropriate thing for someone who occupies his place in public life combining trendy finance and debatable climate change action. He’s doing a PhD at RMIT University’s Blockchain Innovation Hub, studying “alternative models for carbon markets through tokenisation and the development of derivatives markets”. Well, indeed.

Extremism on both sides is pretty depressing

While it's still early days in knowing fully what happened in the ambush of police in (what I think I can call) outback Queensland, it does seem already established that the perpetrators were all Right wing, anti-government conspiracy believers, who (perhaps most bizarrely of all) had each worked in significant roles in the government education system, despite that workplace having (pretty fairly, I would say) a reputation as being the home of Left leaning staff.   This was the type of murder that is more expected from the backwoods of rural America than Australia, but it does show the harm that the internet causes in easing the spread of conspiracy belief, and the reinforcement effect of people finding forums on line where others listen to them, and offer support (or at least, fail to condemn.)

I'm also feeling somewhat depressed about the state of Twitter, and in particular, damaged-manboy-who- just-wants-to-be-liked, it-doesn't-matter-by-who Elon Musk giving endorsement to Right wing conspiracy and extremism, and ruining people's lives.   It is absolutely appalling, in my books, that Right wing commentary in the US and here ignores the matter of death threats that are guaranteed to be made on the basis of Right wing conspiracy - the election workers who get harassed for just doing their job; anyone caught up in the "maybe he's a pedo" moral panic which is deployed freely by Musk personally.

On the other side of politics, there is also an extremism that is bothering me, and even though it is not as patently dangerous as Right wing conspiracy, it is annoying me that it is not being called out.   Take this as an example:


Kilroy is a bit of a lawyer celebrity:  she did time in jail for drug dealing as a young woman, got herself educated, and went from social work to a law degree and finally got admitted as a lawyer in Queensland despite her troubled past.   She is well known as an advocate for improving conditions for women in prison.   She has featured on "Australian Story" on the ABC.

Yet this comment, which I suspect she was inspired to make because a Victorian commission into child protection has been full of claims that it's just obvious that too many aboriginal children are being removed from families, is just patently extreme and silly.   It's of a class of the increasingly radical young aboriginal activist line that Australia just needs to be handed over to First Nations people and that will fix all of history's wrongs.  

It seems to be, reading the Tweets of First Nations academia (which I have been doing via one particular person always coming to my attention there), that the women in that field (as it is mostly women) live in an intellectual space that allows them to repeat to each other statements of escalating extremism, and they simply have no incentive to talk each other down.

This is bad in its own way, and I wish that the mainstream of politics - and reporting - would stop letting this happen with no pushback.  

If someone says something on line that is ridiculous and extreme, whether it is from the Left or Right, and they are being interviewed on the ABC or where ever, they should be challenged about it.  

I don't see that any good comes from pretending that the extremism doesn't exist, on either side.   

Update:  another couple of recent tweets from Ms Kilroy:

The fine print (that's continually overlooked)

Obviously, while she is getting quite well known, not enough people have seen Sabine Hosenfelder's video from last year about the huge amounts of energy that are needed to drive the systems needed to get "net energy gain" in experimental fusion.  Here's a link to it again.

Oh, and look, the Washington Post story about the "big breakthrough" at one facility, has this fine print, which really, honestly, should be reflected more in the headlines:

“If it’s what we’re expecting, it’s like the Kitty Hawk moment for the Wright brothers,” said Melanie Windridge, a plasma physicist and the CEO of Fusion Energy Insights. “It’s like the plane taking off.”

Does this mean fusion energy is ready for prime time?

No. Scientists refer to the current breakthrough as “scientific net energy gain” — meaning that more energy has come out of the reaction than was inputted by the laser. That’s a huge milestone that has never before been achieved.

But it’s only a net energy gain at the micro level. The lasers used at the Livermore lab are only about 1 percent efficient, according to Troy Carter, a plasma physicist at the University of California, Los Angeles. That means that it takes about 100 times more energy to run the lasers than they are ultimately able to deliver to the hydrogen atoms.

So researchers will still have to reach “engineering net energy gain,” or the point at which the entire process takes less energy than is outputted by the reaction. They will also have to figure out how to turn the outputted energy — currently in the form of kinetic energy from the helium nucleus and the neutron — into a form that is usable for electricity. They could do that by converting it to heat, then heating steam to turn a turbine and run a generator. That process also has efficiency limitations.

All that means that the energy gain will probably need to be pushed much, much higher for fusion to actually be commercially viable.

At the moment, researchers can also only do the fusion reaction about once a day. In between, they have to allow the lasers to cool down and replace the fusion fuel target. A commercially viable plant would need to be able to do it several times per second, says Dennis Whyte, director of the Plasma Science and Fusion Center at MIT. “Once you’ve got scientific viability,” he said, “you’ve got to figure out engineering viability.”

And yet the article still ends on a rather misleading note:

Current fusion experts argue that it’s not a matter of time, but a matter of will — if governments and private donors finance fusion aggressively, they say, a prototype fusion power plant could be available in the 2030s.

“The timeline is not really a question of time,” Carter said. “It’s a question of innovating and putting the effort in.”
The article didn't even mention the other well known problems of practical fusion power:  how to deal with the physical container getting radioactive from neutrons (or at least, at a slow enough rate that it doesn't become prohibitively expensive), the supply of tritium issue, and other matters which are detailed at links in my post of 2019.

It just seems that people are having a hard time believing that scientists involved in this type of research are prone to exaggerated optimism.  Why are there so few articles exploring this in depth in the mainstream media?? 

 

 

 

 

Fantasy world noted


I'm wondering what happens if a very rich man with a Messiah complex gets a brain implant that allows external control by others, only to have the input to it hacked by his "woke" critics.

I can imagine some very operatic endings for Musk too - like jumping in a Starship before it's properly certified, and blowing himself up.   

Speaking of the thrill that the conspiracy rattled brains of the planet are getting from Musk's continued descent into inanity:

How much longer can liberals keep using Twitter?

There are increasing numbers of the liberal types which I follow on Twitter saying "that's it, if Elon Musk wants this to be a Right wing conspiracy nuthouse, full of abuse, he can have it" and saying they are leaving.

This is, I should add, fully deserved.  His slimy "maybe he's a pedo" innuendo against his former employee, and ridiculous tweet on Fauci are more than enough reason.   It seems he doesn't care if the platform becomes pretty much the same as its Right wing rivals;  and he tweets with the obvious intention of getting attention from everyone, and the approval of the worst of the Right.   

The problem is that the alternatives are still not ready.   Maybe it's hard raising the money on the promise that a substantial chunk of Twitter users will flock to the liberal Twitter alternative?

Anyway, I hope it happens soon.

Lamb recipe noted

I don't know what it is about Irish stew that I don't find appealing, but part of it may be that it is often made with lamb neck chops, and the fact that they make it a little too obvious that you're eating vertebrae chopped up is a bit unattractive.   I don't mind osso bucco and the way it makes it clear you're eating a cross section of leg bone, but vertebrae and that bit of spinal cord in the middle - it's getting more "personal" or something!

Anyway, I still bought some neck chops on the weekend, as they were (relatively) cheap [for future historians reading this - $19.95 a kilo] and I decided that there must be a more interesting way to eat them than boring old Irish stew.

So I tried this recipe:  Italian lamb neck chop stew, and the result was pretty pleasing.  (I fiddled a bit with it - a chopped up fennel bulb went in too, and used chicken stock instead of vegetable, and a bit of red wine.  I also used panko crumbs for the topping [fried with a little bit of chilli flakes in the oil, then add lemon zest and minced garlic right at the end so the garlic doesn't burn.]  Worked well.)   Technically, I'm not sure it's a stew, which I would have thought is normally done on a stove top.  I would think it is more likely a braise, since it's done in the oven.

Somewhat mysteriously, although the recipe says to scoop off some of the oil at the top while its cooking, very little appeared, and it couldn't really be done.  The chops did have a fair bit of unremoveable marbling in them, so I was expecting it to be heavy in the oil department, but somehow it wasn't.  It was eaten with some thick sourdough toast, and microwaved asparagus. 

So, success all round.

"You may now urinate"

I am somewhat amused by the earnestness of this report by Singapore's CNA about an automated urine testing system (for drug offenders who are monitored) which they say is a "world's first": 

 

You just know that any other network on the planet would not have been able to resist a pun or some attempt at humour. But not CNA.
