This is an interesting Comment is Free article at The Guardian - arguing that Christianity really caught on as a result of a plague in the 3rd century which made a religion with a teaching and obligation to help the poor and suffering look much better than the pagan religions, in which the gods were capricious and mainly to be feared and appeased.
I wonder if some will challenge the image of pagan religion this relies on, though?
And now, let's ask Musk's AI thingee Grok to generate a nativity scene featuring New Jersey drones:
I guess the bearded Mary is the highlight, and is particularly ironic given it's the vision of anti-woke Elon's AI; but what on Earth is the ground covered with? The shed itself is in groovy 60's psychedelic style too, for some reason. And baby Jesus looks like one of those dolls made by stuffing stockings.
I see that Ireland is having second thoughtsabout being a hub for AI data centres, due to the huge amount of electricity and water they eat up. AI results like the above should make them even more concerned...
I'm finding it a bit hard to think of a worse year over the last several decades, in a "reasons to feel optimistic about the direction the planet is heading in," sense. I guess people may have felt this way in (say) the mid 70's - a far from happy decade - but I was still somewhat of a techno-optimist at that stage and had a teenage life to live.
But gee, I mean - now we have the whole Middle East a complete humanitarian disaster again; much of Africa in terrible governance and humanitarian crisis, again; the danger to the West and Western interests from Russia and China, again; the unbelievable election of Trump, again; the loonies he wants to put in control and the drug addled, power hungry billionaire who helped put him in place (well, I guess this not a case of again - it's like a bad gothic Batman story come to life for the first time.) Another Christmas market terror incident in Europe just puts the cherry on top.
Also - overlaying all of this (which was not the case in the 70's) is the global climate disruption that Right wing (mostly ageing) idiots still refuse to acknowledge, and which we can only deal with by waiting for them to die.
Anyway, I'm talking about the vagus nerve because of this interesting story at CNN:
Fournie had been married to his longtime sweetheart for two
years, and had no reason to suspect he had any mental health issues.
“I just thought to myself, ‘If this is it, if this is all
there is to life — if it ended now, I’d be OK with it,’” Nick, now 62
and based in Illinois, said of that fateful day outdoors nearly 40 years
ago.
But one day as he was mowing the lawn, his perspective on life abruptly
flipped from light to dark. The shift would set him and his wife, Mary,
on a tumultuous, yearslong journey of fighting for his well-being and
another chance at a happy life together — until they learned of an
alternative, obscure treatment that would change everything.
I wonder how often that happens - I am much more used to the idea that it develops somewhat gradually, or perhaps as a result of a sudden crisis such as a nervous breakdown.
In 1773, US polymath Benjamin Franklin argued that scientists should try to invent a method of embalming such that a human could be revived in the future. He admitted “a very ardent desire to see and observe the state of America a hundred years hence”. Neuroscientist Ariel Zeleznikow-Johnston thinks that such brain preservation and revival could well become feasible. But his complex book acknowledges this proposition as “scary and disquieting” — requiring us to scrutinize our own mortality, “a deeply unpleasant task”.
The book is The Future Loves You. The description at the publisher's site is:
A brilliant young neuroscientist explains how to preserve our minds indefinitely, enabling future generations to choose to revive us.
I look forward to reading a lengthier review!
Anyway, I am surprised at the observation of Benjamin Franklin - quite ahead of his time there. (I see that Frankenstein wasn't published until 1818, and I presume it may have popularised the concept of revival of the dead.)
You sure want to pick the right 100 year period to be revived in, though. I mean, he died in 1790, and although the world of 1890 had undergone the industrial revolution, it had got nothing on the changes between 1890 and 1990. I'm not sure we'll ever see anything quite like that century again, in fact!
I think the Medical Journal of Australia used to run humorous short pieces at Christmas, so I had a look at it today, and instead became depressed while reading this article:
It's open access, so you can read it and marvel too at the intensity of what I sometimes describe as "sociology talk": the use of a terminology invented for their own field and which has gone on to become the navel gazing justification for academic careers: whole careers devoted to taking to talking to each other about their own terminology and world views, and telling others that they just don't get it like they do.
Now, I know: you could have the same criticism of philosophy, which is a field I am generally sympathetic to. But at least philosophers don't turn up at government meetings arguing that their insights are crucial to solving social disadvantage - they by and large have the good sense to let economists worry about economics, and doctors and epidemiologists worry about improving health, and so on.
To clarify: it's not as if I am one to think you ignore everything (say) a remote indigenous community thinks about their health services if you want to improve it. But that's the immensely irritating problem I have with the likes of this article: its insights could be condensed to something like this: "indigenous people come from a different cultural background, and it pays to try to work with them and take their views into consideration when trying to improve their health services."
But no, let's spend money on career academics and researchers and their conferences that spin a simple principle into well paying careers of waffle.
Here are some key paragraphs:
Decolonisation
Colonisation stems from, as well as perpetuates racial
imbalances of knowledge, knowledge production and knowledge practice.
Decolonisation and decoloniality are a few of many tools used in
attempts to dismantle, hinder, reverse, stop or remove colonising
practices, with the aim of privileging the rights of Indigenous people.13,20,21,22
We acknowledge the various, and sometimes conflicting
conceptualisations and applications of decolonising and decolonial
practices. These conflicts are influenced by place, people and
socio‐political contexts, including the lack of transformative actions
that should be of benefit to Indigenous peoples.21,23,24,25,26
Three key features, of the many, relating to decolonial and
decolonising practices that we implement in our team are described
below.
Establish and understand positionality
Positionality is where one speaks from; it is reflective of values, beliefs and worldviews and how these underpin daily life.1
For Indigenous peoples, positionality is reliant on relationality,
whereby relationships to Country, family and community underpin values,
beliefs and worldviews.1,3
Positioning includes one's professional context and intentions of
research, as much as it is about positioning within the workplace.21
Furthermore, understanding one's workplace and the relationships formed
with Indigenous communities, past and present, is essential.
Positioning in context of colonisation is also important. Non‐Indigenous
people need to understand their own positioning in relation to
colonisation, including privileges associated with unearned power.20
Whereas Indigenous peoples' positioning with colonisation is linked
with both historical and contemporary forms of oppression, which aims to
eradicate Indigenous peoples and knowledges. Indigenous peoples have
another link to colonisation; one that is associated with survival,
resistance and a reclamation of Indigenous Knowledges and practices
The reasons he presents for this seem way, way, more about his good mood after a holiday, rather than a serious consideration of evidence.
If anything, even if you restrict the view to the USA, the fact that even Catholics have swung to a character like Trump should give more grounds for pessimism about the future of religions, rather than optimism. I mean, here is the Washington Post talking about the Trump flunky just appointed to be his Vatican ambassador:
Burch co-founded Catholic Vote, a lay advocacy group in 2005. The organization backed Trump in 2020 and 2024. Burch is the author of the 2020 book, “A New Catholic Moment: Donald Trump and the Politics of the Common Good,” and co-author of a 2021 book “America Catholic Daily Reader,” about Americans who have been shaped by their Catholic faith.
According to exit polls, Catholic voters supported Trump over Vice President Kamala Harris by a 20-point margin. In 2020, Catholics backed Biden, who would become America’s second Catholic president, by a five-point margin. In both years, just over 1 in 5 voters were Catholic.
The only reason I think Ross can sense a mood swing might be around certain culture war ones such as the extremes of trans rights. But just because the extremes of identity politics might be undergoing some successful pushback hardly means a return to mainstream religion in the population overall.
You
have a foot in each of two worlds, faith and academia, that often seem
like rival sides of the God gulf. Can we find paths of mutual respect to
bridge that chasm?
The
Gospels most often speak in the language of stories and poetry.
Intellectualizing these traditions — or turning them into dogma —
doesn’t make them spiritually deep. What we call Christianity is not a
single thing. Instead, it consists of a 2,000-year-old collection of
stories, prayers, liturgies, music, miracles — sources drawn from
traditions as different as Eastern Orthodoxy is from Pentecostalism or
Christian Science. No one can swallow the entire tradition: It’s
undigestible. Instead, anyone who identifies as Christian chooses
certain elements of it.
A professor
friend said to me: “I’m an atheist. How can you believe all that stuff?”
First of all, as I see it, “believing all that stuff” is not the point.
The Christian message, as I experienced it, was transformational. It
encouraged me to treat other people well and opened up a world of
imagination and wonder.
Your own faith journey seems to
bridge the chasm. You were raised in a household hostile to faith, then
became an evangelical, then had a crisis when a friend died and you were
told he wouldn’t go to heaven because he was Jewish.
When some
Christians said to me that non-Christians are going to hell, I left
their church. That made no sense to me. What about Jesus’ message of
God’s love? At that point I left Christianity behind. For some people,
there’s no middle ground. You’re either in or out — that’s how it’s
often practiced. So for years I was out, although I knew that something
powerful was there. But after years of being out, I kept wondering, what
made that encounter with Christianity so powerful?
So
I had to go back, asking questions. How were these stories written? How
do they affect us so powerfully? They speak to a deep human longing for
a sense of transcendence and spiritual experience. For we can respond
to the same story in more than one way. As a historian, I question the
literal truth of the virgin birth story. But I still love the midnight
service on Christmas Eve, where the story is gloriously told and sung as
miracle. As poet Seamus Heaney writes, “Believe that a further shore /
is reachable from here. / Believe in miracles.”
But I guess I have to wait for Sabine Hossenfelder's view on it before I can tell how seriously to take it!
(And I wish the article did more to explain the "'timescape' model of cosmic expansion". Or did Sabine already talk about this? It's hard to remember, she puts out so much content!)
This section, for example, explains stuff that is very often missed out in the discussion:
First,
as ice melts in Greenland or Antarctica, meltwaters spill into the
ocean, raising global sea levels everywhere. But, counterintuitively,
the coastlines farthest from the ice sheets are hit hardest.
That’s
because the ice sheets are gigantic — so gigantic, in fact, that they
exert a gravitational pull on the ocean. (The Greenland ice sheet weighs
approximately 2.7 quadrillion metric tons, equal to about 450 million
Great Pyramids of Giza; the Antarctic ice sheet is 10 times heavier.)
Normally,
that enormous weight pulls oceans close to the ice sheets, making sea
levels around Greenland and Antarctica higher than they would be
otherwise. But as the ice melts, that effect lessens. Sea levels close
to the ice sheet fall, and sea levels farther away rise.
Jerry
Mitrovica, a professor of earth sciences at Harvard University and one
of the leading experts on melting ice sheets and ocean levels, recalls
looking at a plot of sea levels near Greenland. “I couldn’t believe it,”
he said. “It was just an incredible thing to see around this melting
ice sheet that sea level change, at least regionally, is dramatically
going down.”
Researchers use satellites to track this effect. TwoGRACE
Follow-On satellites, launched in 2018 by NASA and the German Research
Center for Geosciences, orbit the Earth about 140 miles apart — as they
do, subtle changes in Earth’s gravitational pull yank onefarther from the other. Those shifts paint a picture of the planet’s gravity,which scientists can use to predict the precise pull of the ice sheets on ocean waters.
which I haven't read in full (paywall), but the point appeals to me:
My father-in-law, with whom I was very
close, spent most of his life on the same working-class street in
Barcelona’s El Clot neighborhood. Born in 1929, he saw Spain’s bloody
civil war taking place literally in front of his house. His family
experienced a lot of suffering. Some died; others spent years in jail or
were forced into exile. He himself spent a year in a refugee camp, an
experience that affected him for the rest of his life. Every time he
wanted to make a point about society or culture, he always started with:
“Well, during the civil war …”
One evening, a few months before he died, he read in his local paper an article of mine about unhappiness. “You have a lot of complicated theories,” he told me, “but the real reason people are unhappy is very simple.” I asked him to elaborate. “They don’t enjoy their dinner,” he responded. I asked him what he meant. “Well, during the civil war, we were always hungry,” he said. “But one day a year—Christmas—we got to eat whatever we wanted, and we were so happy. Today, people snack all day long, are never hungry, don’t enjoy their dinners, and aren’t happy—even on Christmas.”
Would I be happy with an Atlantic subscription? Possibly. Digital is $90 (US) a year. Maybe I ask the family to each pay a third.
Meanwhile, I still, lazily, haven't decided if I should drop the NYT or WAPO. I feel I only need one.
* Clive Robertson, the cranky persona-ed news reader and broadcaster, died last week. I hadn't thought about him for years, but his death reminded me how much I used to enjoy his late night news show. His droll, dry wit was very amusing, and I miss that we have nothing similar today.
* Australian author John Marsden has also just died (at only 74 - as I age, I long to read only about deaths that are at older ages than that!). I only read his famous first book in the "Tomorrow - When the War Began" and thought it was OK, but I knew he had been very influential in the youth fiction market, and in youth education generally. I didn't recall this:
John’s youth was harrowing in different ways, and he never hid the fact
that he was a bit bruised by life. He became suicidal as a university
student and was institutionalised; he once wrote that the world of the
psychiatric hospital was in some ways “more real than the one outside.
In here the masks are off, people don’t pretend so much. [They] don’t
have the energy or strength.” Perhaps that’s why he was able to inhabit
his characters so fully. It is extraordinary for a man of his generation
to write teenage girls so convincingly and with such empathy.
Update: yes, as Tim points out below, now Michael Leunig has died, aged 79. (Again, fellas, for my long term planning, I only want to see people start to leave this mortal coil from about 85!) I guess like most people I didn't mind Leunig at his peak, but his brand of idiosyncratic eccentric takes did start to wear thin in the long term.
If anything, I reckon it was way, way too gentle on Musk, even though she doesn't think his plans will happen any time soon.
She spends too much time on the long term difficulties of permanently colonising Mars (the issue of it not being to retain an atmosphere due to solar wind is covered, for example) without talking enough about the short term wild implausibility of Musk's fantasy - the huge number of rocket builds and launches needed, the totally tricky orbital re-fueling that has not been tried and is (I reckon) always going to be a high risk manoeuvre - probably with the potential to create a huge mess of orbital debris - and the routinely overlooked matter of how difficult it will be to build a biologically self supporting colony on Mars.
I think this latter issue is just common sense - look at the problems the Biosphere experiment went through, and that was on a planet where all the organic material needed could just be driven in on the back of a truck.*
At least I saw some support in the video comments for my view that if you want a "lifeboat" for planet Earth, why not build it on the Moon? (The only plausible reason against it that I can think of is that no one knows what effect low gravity pregnancy will have on the babies - but then, the same might turn out to be an issue in Mars gravity too. Wouldn't it be ironic if it turns out it's really, really difficult to carry a baby to term in low gravity, for some reason we have no idea about at the moment. That would ruin Musk's "longtermism" pretty rapidly.)
I remain very confident that Musk will face a downfall sooner or later, and people will wonder why more experts didn't speak out about his wild overconfidence earlier...
* Have a look at the website for a long on-going research project of the European Space Agency to develop a closed system for life support, including food, called Melissa. As far as I tell, they might be up to trying it out on a small rat colony. And I liked this part from their FAQ page:
Why after 30 years the project is not finish yet ?
The proper answer to this one is probably:
Why man has no try to duplicate the
Earth functions earlier ? In other words, although humans are fully
depending of the Earth ecosystem functions (e.g. oxygen, water, food,
...), we have today no back-up. Anyone who looks a bit more carefully to
the challenges of artificial ecology will rapidly perceive the enormous
difficulties. We have seen over the years many similar projects :
CELSS, CEEF, CERES, BIOSPHERE 2… almost all of them had to stop due to
incorrect evaluation of the challenges, and necessary amplitude and
duration of the efforts.
Yeah, I've slowed down a bit in my reading of the abridged version of Journey to the West, and I note as follows:
a.it takes to about the half way point of the book before the journey actually begins;
b.I am now 55% percent in, and we still haven't met the 4th travel companion (Sandy in the TV series);
c.I was rather surprised that in Chapter 17, the Heart Sutra suddenly appears in full. I had just watched one of the Doug's Dharma videos on Youtube in which he spoke about it.
Stancil, who it seems annoys a lot of people for reasons unclear to me, has (along with David Roberts) been one of the most consistent messengers about how that the Left needs to start paying much more attention to the inherent damage the information environment (including its speed and ease of manipulation) has caused.
So, we're getting a fair bit of handwringing over much of the public reaction to that US health fund executive being murdered:
While I agree that it's not good to celebrate vigilante actions, I'm also on the side of those on the Left who think that the Right complaining about bad taste is too often used to sustain a bad status quo.
And it has made me finally post a thought I've had about Trump for years.
As a growing body of research reveals,
Black people in the United States suffer the hallucinations and
delusions of psychosis — the voices that seem to emanate from outside a
person’s head, the visions, the paranoias, the breaks with common
reality — at a rate roughly twice that of white people. In Europe,
racial disparities regarding psychosis are yet wider. Even after
researchers control for socioeconomic factors and address issues of
diagnosis, the alarming racial gaps remain.
Studies
suggesting a link between minority or outsider status and psychosis run
back about a century. A 1932 study looked at hospital admissions for
psychosis in Minnesota. It found that Norwegian immigrants were admitted
at twice the rate of native Minnesotans or Norwegians in their home
country. By the 1970s, researchers were turning specifically to racial
divides in psychiatric disorders, and by the 2000s, the relationship
between race and psychosis (which appears to outstrip any correlation
between race and more common conditions like depression) was becoming
well studied in both the United States and Europe. Yet despite the
mounting data, in the United States, until recently, the issue was
relegated to the edges of mainstream psychiatry — or perhaps beyond the
edges.
The whole thing is pretty odd, as explained in this part (with my bold):
In the United States, Black-white ratios
are at least 1.9 to one; some studies show that disparities for nonwhite
Hispanics are narrower but still notable. In Europe overall,
Black-white differentials hover in the vicinity of four to one. In
England, the gap for Black Caribbean and Black African immigrants runs
between four to one and more than six to one. In the Netherlands, for
Moroccan, Surinamese and Antillean immigrants, the ratio is around three
to one.
Among the immigrant groups,
one plausible factor is the dislocation and stress that can come with
the immigrant journey itself. But while such trauma may seem an obvious
trigger, given that many immigrants arrive in their new nations after
dangerous journeys and unable to speak the language that surrounds them,
researchers have found repeatedly that second-generation immigrants to
the United States and Europe develop psychosis at rates at least as high
as their parents. Something is happening in the new country.
Compared to some people, I suppose I have pretty small exposure to social media, given that Twitter (and now Bluesky) was my only real social media app (if you don't count blogs with active threads - now a rarity - or YouTube). And one of the problems of Bluesky now being pretty good is that I am finding it too easy to just keep...on...scrolling...scrolling (and often avoiding reading the in depth articles sometimes linked.)
Earl Miller, an MIT neuroscientist and world expert on divided attention, warned in 2022 that we are now living in “a perfect storm of cognitive degradation”. Dr Gloria Mark, professor of informatics at the University of California and author of Attention Span, has found evidence of how drastically our ability to focus is waning. In 2004, her team of researchers found the average attention span on any screen to be two and a half minutes. In 2012, it was 75 seconds. Six years ago, it was down to 47 seconds. This “is something that I think we should be very concerned about as a society”, she told a podcast in 2023.
But we’re not entirely to blame if technology is making us less intelligent. After all, it was designed to captivate us totally. Silicon Valley’s dirtiest design feature – which is everywhere once you spot it – is the infinite scroll, likened to the “bottomless soup bowl” experiment, in which participants will keep mindlessly eating from a soup bowl if it keeps refilling. An online feed that constantly “refills” manipulates the brain’s dopaminergic reward system in a similar way. These powerful dopamine-driven loops of endless “seeking” can become addictive.
What will happen if we don’t get a handle on our declining cognitive health? The former Google design ethicist Tristan Harris told US Congress in 2019 that billions of people – “a psychological footprint about the size of Christianity” – now receive their information from platforms whose business model “links their profit to how much attention they capture, creating a ‘race to the bottom of the brain stem’ to extract attention by hacking lower into our lizard brains – into dopamine, fear, outrage – to win”.
His warnings are about as stark as they come. “Persuasive technology is a massively underestimated and powerful force shaping the world,” he said. “It has taken control of the pen of human history, and will drive us to catastrophe if we don’t take it back.”
The worst thing about it (internet brain rot) is likely the loss of book reading amongst everyone, especially the young.
I have been meaning to say for some time, but as I get older, I am surprised that I am still drawing connections between my life experience and some incidents in novels that have stuck in my head from what I might have read 30 or 40 (or more!) years ago. What I mean is - I have just recognised the truth or insight in the writing that long after reading it. It's quite surprising, and I just can't see people who have grown up in social media (with ruined attention spans for reading novels) being able to have the same experience, and it does feel like a real loss, but they won't realise it....
In 2023, the global mean temperature soared to almost 1.5K above the
pre-industrial level, surpassing the previous record by about 0.17K.
Previous best-guess estimates of known drivers including anthropogenic
warming and the El Niño onset fall short by about 0.2K in explaining the
temperature rise. Utilizing satellite and reanalysis data, we identify a
record-low planetary albedo as the primary factor bridging this gap.
The decline is apparently caused largely by a reduced low-cloud cover in
the northern mid-latitudes and tropics, in continuation of a
multi-annual trend. Further exploring the low-cloud trend and
understanding how much of it is due to internal variability, reduced
aerosol concentrations, or a possibly emerging low-cloud feedback will
be crucial for assessing the current and expected future warming.
Of course, how to work out the net effect of clouds has been one of the main bugbears of climate modelling. The skeptic hope was that higher temperatures would mean more cloud and more albedo to keep the earth from getting too hot. (I thought that was how the late Richard Lindzen's iris effect idea worked, but now that I double check, it was more that cirrus clouds would reduce and allow more IR to escape - so I'm not sure if an increase of lower, brighter clouds was actually part of that theory or not.)
Anyhow - it remains a major worry that it is unclear whether the modelling has got the cloud effects underestimated, so that global temperature increases could be more rapid than expected.
Gavin Schmidt at Real Climate has a brief commentary on the paper here. There is quite a bit of talk in the comments following about whether to credit reduced sulphur emissions from shipping as causing the albedo decrease, too.
The story over the last week or so about people claiming there is a lot of unusual large drone activity in the night skies of New Jersey is pretty intriguing.
I get the feeling that there is something to it - some of the descriptions of a line of drones one after the other seem unusual. But - if it is a company trying out some new tech, it's hard to imagine why they (or the authorities wouldn't be open to it. That's why it's intriguing.
I have mentioned once before though - it does seem at times that the airspace over parts of the US is not as well monitored as one might assume. Maybe too many things going on to keep track of all of it?
I see that the Bluesky user counter shows a considerable slowdown in the rate of sign ups since it hit 24 million. It will take quite a while at this rate to hit 25 million.
That's a pity, because it really has already become a good Twitter replacement. The only thing I kind of miss is a "trending" list - but half the time those was false alarms anyway. "Why is this person suddenly trending - has he/she died?"
I would also like to see more local accounts so that I could search for comments on breaking local news.
Speaking of comedians, Ronny Chieng has been on a roll hosting the Daily Show this week. This day's clip was particularly good I think - every joke seemed to hit:
The Junkyard, managers of Australian comedians like Aaron Chen and Sam Campbell, goes into administration
Let it be known that, of the younger Australian comedy set, I've always enjoyed Aaron Chen's comedy persona. That Sam Campbell - well I first saw him recently on an episode of Would I Lie to You (english version) and it was a few years old, but he seemed amusing in a similar eccentric persona to Chen. But then I think I watched some other clip of him on Youtube and didn't like it, so I dunno.
Anyway, back to the point: about the only fictional portrayal of a talent agent I can remember is from that Matt Berry series - Toast of London. And it fitted in with what is probably a widely shared assumption that actor's agents sit around doing nothing much all day other than reading the occasional casting call news and ringing up people on their list and saying "why don't you try this, I think it suits you". It seems like such a flaky way to make a living - even if, in the case of top Hollywood agencies, it's a very lucrative one.
But is it really like that? Does no one do a realistic portrayal of this line of work because it's hard to make "networking" interesting?
Update: Maybe there was an agent or two featured to a little extent in Bill Hader's dramedy Barry. But I think that shows attack was more against the incredible flakiness of cable television executives. In fact, I found it kind of amazing that the executives at (I think) HBO let such a damning portrayal of their job be part of the story! I presume they thought - it's not our network's execs he's attacking - it's the one down the road.
Gee, this has become a pretty familiar story - a small start up company manufacturing a clean, green energy product that just doesn't stack up in quality and reliability, then goes broke and tarnishes the reputation of clean energy overall:
A similar story happened in 2009 with some Stirling engine solar power plant that might have looked cool, but never worked well. (I see now that even the webpages for the long defunct American Stirling engine solar power company Infinia are gone! I always liked the look of their dishes. There's a photo on one of my posts from 2008.)
Not to mention failure to develop geothermal power in Australia: see this story, and this one.
[Oh, and I nearly forgot - the failure of various wave energy schemes. Frankly, this idea has always seemed to me to be extremely dubious - my gut feeling was always that there is too little movement in any single device riding waves to generate significant enough power to be worth the expense and maintenance.]
The common theme seems to be that they are not crank schemes per se (in that they are systems obviously capable of making energy) - but they need a lot of finesse to make them reliable and economical. Small companies grab the idea but don't have the resources to make it work like it should - and unfortunately, can start to sell the systems before they are proven.
Seems to me that what it all lacks is big companies with the resources to build and test properly the systems before selling them.
Following last weekend's flash flooding around parts of Brisbane, the ABC has this article up:
More wild weather forecast for Queensland raises questions about how Brisbane drains handle intense rainfall
with one guy saying:
"With the bureau forecasting more frequent events, the storm drains across the city simply aren't designed to take in flows of run-off and intense rain," Mr Winders said.
Rather than being flood-resilient, Mr Winders suggests residents need to become "storm-resilient".
"The local council can't do anything about the network, the drains are already in place and there's too much existing development," he said.
"All these things impede the ability of the council to provide any relief from local flooding."
And I suspect he's right.
One thing that isn't mentioned in the article, and that I'm pretty sure would be true, is that Brisbane's drainage system does seems to often handle much higher total rainfall events without flooding, compared to cities such as Melbourne, and probably Sydney too?
I mean, over the years, I have seen many news reports of flash flooding from storms in other cities, and the rainfall totals that caused it often seem to be well under the rainfall we hear about in Brisbane storms or rain events.
So I have always suspected that our drainage system has been engineered to expect higher surges than those of drier cities. (Melbourne in particular seems to get most of its rain in far less intense events than Brisbane - it's just spread out over drizzly days rather than in 10 or 15 minute bursts like here!)
* A month or so ago, I posted about whether or not I should go see a performance of Beethoven's 9th (for the first time.) I was encouraged to do so, but delayed buying tickets. I checked about 9 days ago if seats were available, and some were, but I still didn't book. Then, on Sunday, I thought I should check again - then thought "whoops - it's December!". I had become so busy with one work matter that I had completely forgotten the concerts were on last Thursday, Friday and Saturday. :(
When the seated choir (Brisbane Chamber
Choir Collective) rose to their feet, we were in for a surprise.
Unexpectedly, around the concert hall – in the stalls and side balconies
– other choir members also stood with opened books. Undercover,
plain-clothes, choral operatives had been inserted into the midst of the
unsuspecting audience.
As the instrumental and vocal volume
swells, Clerici is conducting a 360-degree enterprise. The sound is
heavenly, harmonious. Beethoven has played his trump card. The pitch
rises as the beautiful voice of the soprano soloist soars above the
music and the choir.
The performance earns the orchestra and
conductor a standing ovation. Orchestral sections are individually
applauded. Clerici shakes hands warmly with the concertmaster, Natsuko
Yoshimoto. As the soloists exit, Umberto bows graciously to the two
women before giving the baritone a hearty high-five. A tremendous
performance by our state orchestra and a triumphant conclusion to the
2024 season.
Ugh...
* There was flash flooding yet again in Brisbane last Sunday, yet oddly enough, in my corner of the city, it got dark and a bit thundery, but virtually no rain at all. Only 15 km down the road, people went to a well know pub car park, only to get their cars inundated:
This spring and early summer in Brisbane, and the south east generally, has been so wet that it is making me worried that Brisbane is in for yet another flood this summer. I checked the SEQ Water dam levels, and virtually all are full or overflowing, except for Somerset and Wivenhoe (the ones that protect the Brisbane River from flooding) and they are at 80%. (The last time I checked, about 3 or 4 weeks ago, they were 80% then, too. I'm guessing water is being released enough to keep it there.)
But, gee, I don't know. Seems to me it wouldn't take too much more torrential rain in the right spot to cause another major flood.
* So, Biden pardoned his son. I can't get too excited about it, especially with the absolute nutjobs who Trump wants to appoint who seemingly want to spend another 4 years of wasted effort on trying to pin corruption on him. Jon Stewart isn't happy - but his takes are only right about 75% of the time, it seems...
I saw a video on the "Megabuild" channel on the weekend about how Singapore is massively expanding its port facilities, from the seabed up. It's - kind of amazing:
But - if you don't have time to watch that, you can view instead a good multimedia graphics explanation that appeared a couple of years ago at the Straits Times website here.
It also explains something I was curious about - wouldn't the steel reinforcement that is throughout the giant concrete caisson corrode quickly when its in seawater? Would the whole box be a crumbling mess in 20 years?
Apparently, it's solved by spraying a sealant on the sea exposed parts. Huh.
