Things I don't understand about the electricity "market" in Australia

a.    How do fluctuating "spot prices" work?  I get the impression that move very quickly, but why? 

b.    If a power generating company, whether it be privately or publicly owned, says it can't make profit if the cost of gas or coal is at a certain level, over what time frame are they talking?   Businesses can wear a temporary loss if they make enough profit over the rest of the year - who determines whether these companies are being opportunistic when complaining about a temporary loss due to a temporary spike in cost to generate?

c.    There was talk about how if AMEO set a price, they would compensate companies for the loss caused.  Where does that compensation money come from?   And again, who determines what is reasonable compensation, as that surely involves the question of what a reasonable profit is (which raises the question in b.)

d.    How do the multitude of "retailers" manage to make a difference in price to customers.  I don't understand what an electricity retailer actually does, and why some should be able to offer significantly different prices to customers.

We're getting old

At the Washington Post, an article talking about the 40th anniversary of ET.

It does praise the movie, but I think leaves out two key aspects of its success:

a.    the operatic, deeply affecting, quality of the score.  Does anyone doubt that it contributes enormously to the emotional weight of the key scenes in the last 20 minutes of the film?

b.    although the article does say "Empathy is the film’s guiding philosophy", I would go further than that, and note that it doesn't really feature have true "bad guys" or enemies.  Sure, there are scary police/government officers who try to recover the alien in heavy handed fashion, but a key aspect of the film is that the adults want to "meet" ET too, just that they approach it with adult concerns that are not readily understood by children (the concern for biological contagion).   As with Close Encounters, the conflict is more a case of misunderstanding between groups - not deliberate ill will borne by one lot against another.   In this way, the Spielbergian universe of this era is the opposite of the scare world that the American Right was just starting to talk itself into, with fear of otherness cumulating in Trumpist nativism and demagoguery.   It's no accident that Right wing sites are always waiting to ridicule Spielberg and his movies for being a Hollywood woke liberal - he is their philosophical enemy for believing in a kinder world. 

Meatless Einstein

I seem to have missed that (some) vegans like to claim Einstein as a fellow non-meat eater.

However, as this article from the LA Times explains, he only went vegetarian for the last couple of years of his life.

He did, however, have misgivings about eating meat:

“I have always eaten animal flesh with a somewhat guilty conscience,” he once professed in a letter. He largely agreed with the moral motivations behind vegetarianism, but was unable to comply.

I sympathise.  

I didn't know he had life long "chronic digestive distress".  I should go back and actually read that biography sitting on my bedside table.

How Republicans will move away from Trump

I reckon Allahpundit's explanation of how a move away from Trump within Republicans will work sounds very plausible: 

To repeat a point from yesterday, Republican voters will never admit that the evidence produced at the hearings is damning and should disqualify Trump from being president again. To do so would be disloyal. They might, however, point to the hypothetical effect the evidence will have on swing voters and proclaim that Trump is hopelessly damaged goods. I suspect that’s how Ron DeSantis and other Trump rivals will spin the January 6 evidence if and when they face him in a primary. They can’t tout the evidence as proof of a character deficit but they can say that electability matters above all other things and Trump is no longer electable. The “witch hunt” destroyed him.

As a Republican, you’re not allowed to admit that you believe Trump is unfit for office but you are allowed to disguise that belief as worrying that others might find him unfit for office. Of course he’s fit for office! But … we want to play our strongest hand in 2024, don’t we?

The potential for floating solar power is bigger than I would have guessed

This is the subheading from a Nature comment piece last week:

Covering 10% of the world’s hydropower reservoirs with ‘floatovoltaics’ would install as much electrical capacity as is currently available for fossil-fuel power plants. But the environmental and social impacts must be assessed. 

There is mention of the benefits:

Placing solar arrays on reservoirs could have many advantages. The arrays are simply conventional solar panels installed on floats that are anchored through mooring lines. Proximity to water tends to keep them cool, making floating panels about 5% more efficient than land-based ones⁷. Arrays shield the surface from the sun and might reduce evaporation, retaining water for hydropower, drinking and irrigation⁸. Hydropower reservoirs already have the grid infrastructure for conveying electricity to consumers, reducing transmission costs. Pairing solar with pumped-storage hydropower could address the twin challenges of providing energy when sunlight is weak and storing it as potential energy in reservoirs when solar-power production is high⁹.

I've been saying this for some time....

A futuristic prototype if ever there was one

They were testing this prototype when I were but a boy (in the 1960's), but I am still a bit surprised that I don't recall ever seeing it before.   I think I would have remembered, as it's like a perfect example of what futurism in the 1960's looked like.   (Rather Thunderbirds-ish, don't you think?)

Agreed

Have I ever mentioned before that I was never convinced that the Turing Test made much sense?  I have a vague recollection of arguing with someone about this in the 1980's:

Update:  By the way, my bit of speculation that I think is fun is that sentience in Google (or the WWW generally) might be detected when it becomes clear that it's taking steps to reproducing itself.  Say, orders for new computers or Web components are emailed to a chip manufacturer, with someone discovering they were never generated by a human.

 

I was just complaining about the complexity of energy in Australia last week...

 And read Giles Parkinson on this:

It’s one thing to feel you are being held hostage by privately owned provider of an essential product, but quite another when the stand-off may involve a publicly owned company providing a service as fundamental as electricity.

The extraordinary scenes that emerged in Queensland over the long weekend, and which quickly infected NSW, where generators threatened power shortfalls unless they got paid more money – come from an electricity system – its markets and its regulatory environment – that are completely broken.

It has turned into a state of complete farce when, in Queensland, a state dominated by publicly owned electricity generators – apparently can’t guarantee an essential service because they can’t make sufficient profits.

 Even he doesn't really explain how to fix it properly, though... 

Update:   I suspect JQ  is right - 

Anyone reasonable can see the value in the Jan 6 committee hearings

I watched some clips of the second day of the Jan 6 committee hearing, and I have to say, the manner and questioning of several prominent Republican officials by Democrat Zoe Lofgren was very calm and effective in showing up how there was never anything to the Trump fraud claims.   A summary of 4 key takeaways from the day is here.

I really find it very difficult to believe that this will not prevent Trump successfully running again.  Sure, his deluded followers are not even watching it, and the ridiculous pro-Turmp pundits cannot reverse their opinion while saving any face - but there must some effect of this process on at least enough of the party faithful to not vote for Trump again.

Oh, and here's the Axios summary.  The comments of Allahpundit at Hot Air are worthwhile too.  He points this out, too:  a terrible aspect of the Trump lies that is so badly under-emphasised:

Trump was so sold on the “smoking gun” video that he pressed Georgia officials on it during a phone call a month after it was debunked, even mentioning one of the election workers seen in the clip by name. That woman and another worker were inundated with death threats amid the conspiracy-mongering in December 2020. Their lives have been more or less destroyed since then. As for Pak, he resigned as U.S. Attorney once he found out that Trump was considering firing him for failing to find fraud.  Pak refused to substitute the reality Trump preferred, so he had to go.

Right wingers, and stupid Bill Maher, are very upset that a nutter who planned on shooting a Supreme Court judge was not given enough publicity in the media.

They never talk about the thousands of death threats both Republican officials, and innocent election workers, received all based on a lie of a deranged President. 

More:

And more:

John Hinderaker at the Powerline blog, has moved on:

What we do not need is candidates who are obsessed with righting the alleged (and to some extent imaginary) wrongs that Donald Trump suffered in 2020. I don’t blame Trump for being unhappy, but his emotional state cannot dictate the future of the Republican Party. 

And Trump delusion continues:

You can read it here.  The footnotes are very often to 2000 Mules evidence - which prominent Republican pundits have already refused to support.

Yet more update:  this very damning take on the Bill Barr role at Slate is really worth reading.

He has a point, but still has priorities wrong

Latest Bill Maher kerfuffle:

Bill Maher is calling out Hollywood studios for being super woke on every issue except the most obvious one -- its own culture of gun violence and vengeance, and the role those images play in real-life mass shootings.

Bill got after the issue on Friday night's episode of his HBO show, "Real Time" ... pointing out Hollywood bends over backward to be politically correct, yet "when it comes to the unbridled romanticization of gun violence? Crickets."

Reacting to the recent mass shootings in Uvalde and Buffalo, and the growing cry for Congress to "do something" ... Maher said movie and TV studios also need to acknowledge some cold hard stats.

Such as the fact the average American kid views about 200,000 acts of violence on big and little screens before they turn 18 -- and the FBI says a "fascination with violence-filled entertainment" is a huge warning sign for potential school shooters.

I've been complaining about this for a long, long time too:  I didn't like how the original Matrix showed a world where everyone "not with us is against us" and gave permission for hundreds of normies to be shot up by characters dressed to look cool.    I've complained in recent years about the  "shot to the head, brains sprayed out the back" has become completely normalised in entertainment, such that it contains no shock value at all.    I even quit Squid Games over the violent silliness and am very disappointed that more people did not have a problem with it.  (It's been renewed for a Season 2, I see.  How stupider can the plot get?)

That said:   obviously, the entire world has been watching the same movies and shows and has not been suffering mass shootings in the same repetitive fashion as the US.   Obviously, you can in practice take action on the negative effects of glamorised media violence by stopping the population having such easy access to guns.

It's OK to complain about fictional depiction of violence, but it's not the immediate answer to an immediate problem.

 

Rupert making his feelings better known

So both the New York Post and The Australian have editorialised against a Trump return, and criticised him over the Jan 6 insurrection.  

I'm sure I've posted before that it had been reported that Rupert Murdoch never believed the election was "stolen".   So has he figured he has made enough money from gullible Trump supporters now, and can tell them they're wrong after all?

And he must know that Trumpists will not feel isolated until Fox News evening line up abandons them. 

How is he going to bring that Frankenstein monster to heal?   (Or does he have any desire to - money, money, money, after all.)

 

I wouldn't disagree

From Vox:

The January 6 hearings showed why it’s reasonable to call Trump a fascist

Another weekend update

*  Yes, this has been a remarkably cold stretch for Brisbane - fortunately, from last night, I thought the cold was starting to get less intense.  We just rely on turning split system air con to "warm" if it's cold, and most winters we really don't use them often.   But the last - what? 4 days? - the living room one has been on most of the day.

*  Saw Dr Strange in the Multiverse of Madness.  I rank it a solid "OK".  I don't know why, but I find the world of Dr Strange charmingly silly.  (I liked the way, for example, the guests at a wedding just stand on a high rise balcony watching while said doctor goes to deal with a giant, one eyed octo-monster from another dimension destroying a city street only a block or two from them, and don't run away in mad panic.)   Certainly, in this movie, the reminders Strange gives me of the covers to the Lobsang Rampa books, which I would see in bookshops as a child (but never read) became even clearer.    I guess without Marvel movies, there would be battalions of special effects artists out of work, and who knows what trouble they could get up to if not meaningfully occupied?

*  Oh, it might be something like this:

Google engineer put on leave after saying AI chatbot has become sentient

Yeah, yeah:  this story is wildly popular.   But so it should be, seeing it's like reading a science fiction story come to life:  a company has to seriously explain to one of its engineers why he is mistaken about his having helped create a sentient AI .  Mind you, I, and probably many others, had already begun to suspect broader sentience from Google just from Youtube recommendations.  (I don't really believe this, but I would like to be able to.)    

It's reminding me a little of David Brin's Earth. (Well, the bit about an AI being created - how it came to inhabit the Earth was a bit silly.)

David Roberts wrong for once

Yeah, I trust Noah Smith's take on this a lot more than I trust the (usually) reliable David Roberts's take:

Jonathan Chait's article at New York Magazine on this is also well worth a read (clear your cookies! - or use a browser that doesn't save them.)

 

Australian Fox News drone (insert Jack Nicholson yelling "You can't handle the truth")

Hey, look at old Tom, who seems to spend his days watching either Tucker Carlson or the horse races:

Tom says:

June 10, 2022 at 11:49 am

What we are seeing play out in Washington DC as we speak is unprecedented: a choreographed witchhunt by the Democratic Party against its political enemies, broadcast live from Washington DC by all three major free-to-air US TV networks and all cable news networks, except Fox News, which has refused to co-operate.

It is astonishing because this is happening in the “land of the free” which notionally has a free press.

It is not possible in a free country that the media could collude with a political party to smear (and eventually prosecute) party enemies.

Unless this is arrested, the USA will become a fascist one-party state indistinguishable from communist China or Soviet Russia.

It's truly a Goebbelsian level of brainwashing that the Murdoch family has achieved with their committed audience (of mostly cranky old white men, whose families can barely tolerate having over for dinner anymore).

Update:  from what I can make out from Twitter comments, the hearing has produced a lot of new clips of a lot of people close to Trump (including his daughter!) saying they know the election was not stolen.  It seems to have impressed a lot of people as being much more damaging and compelling than  than they had expected.

 

Energy and politics are a terrible mix

I've felt this way for years, but it's pretty appalling that energy production and sale, and government policy that affects it, is at just the right level of complexity that it becomes incredibly easy for self serving (and sometimes ridiculous) ideas about it to spread because of the mere veneer of plausibility.    For example:

 

And look, I don't understand it at all well either - I just get by on reading a range of material and getting a sense of who is talking more sense about it.

What we need is someone who is seen as a good communicator who can explain the complexities and what is possible and reasonable.   This is part of my "it's time for specifics" arguments too - as far as the plan ahead for replacing coal and gas with alternatives.   Rather than just waiting for the way it pans out now - with intermittent, ad hoc-ish, announcements like this:

Rio Tinto has called for proposals to develop large-scale wind and solar power in Central and Southern Queensland to power its aluminium assets, help meet its climate change ambitions and further encourage renewable development and industry in the region.

The approach, which is through a formal market Request for Proposals (RFP), is intended to support the development of multiple new wind and solar power projects that can, in parallel with firming solutions, start supplying power to Rio Tinto’s Gladstone assets through the Queensland grid by 2030.

Or this:

While on the topic of future energy, John Quiggin's article on nuclear in Australia seemed clear and comprehensible.   But his political allegiances (now, basically "Green") mean he's not going to be seen as a trusted national communicator more broadly on the future of electricity generation and markets, either.   I'm not sure whether he agrees with my concern about the lack of specifics, too.  I should go over to his blog and ask him, I guess!

I didn't even watch the show, but find this funny

On Twitter, David Roberts is talking about looking at episodes from the early seasons of Game of Thrones, and noting how good they were compared to the (apparently) shockingly terrible later seasons - especially the last.

Someone helpfully added this graphic illustration, which I find amusing:

 

 

When technology pushes physics

Here's a lengthy review of a book that concentrates on the development of the telegraph cable in the 19th century, and how these were up and operating before the science of electromagnetism was understood.

I hadn't really thought of this before, but the fact that 19th century technology was preceding the scientific theory behind it has been the theme of the author over several books:

 Hunt’s first book, The Maxwellians, shows how Maxwell’s disciples altered the form of his theory of electromagnetism so significantly after his death that the Maxwell’s equations taught today were unknown to Maxwell himself.¹ In his second book, Pursuing Power and Light: Technology and Physics from James Watt to Albert Einstein, Hunt examines nineteenth-century physics in the glow of nineteenth-century technology.² He shows that, just as Maxwell—and, later, his disciples—pioneered electromagnetic field theory only after telegraph wires already lined the countryside, the science of thermodynamics was developed only after steam engines were already widespread.

Hunt has now published a third volume, Imperial Science: Cable Telegraphy and Electrical Physics in the Victorian British Empire.³ It marries the electrical history of The Maxwellians to the underlying thesis of Pursuing Power—that science is pushed along by technology just as often as it pulls technology ahead.

Interesting!

When progressives go too far

I've read two articles inspired, mainly, by the recall election of the San Francisco District Attorney who seems to be the key one to blame for the rise in crime in the city.

The first appeared in the Atlantic, and seems to be written by a lesbian SF native, who certainly grew up with tolerance to the city's long standing quirks (such as public nudity in parts of it).   Here it is:  How San Francisco Became a Failed City.

The second one is by Noah Smith, who also lives there now.  His essay is broader and covers other aspects where he thinks progressives are facing some well deserved pushback:  The year we all became reactionaries.   

He doesn't cover the trans wars, and seems reluctant to dip his toe into that issue:  but as I keep saying, I reckon the progressive attitude that "there's nothing to see here" in the matter of trans in sports is not going to win in the culture wars.   

Economies of scale, and Mars

Paul Krugman talks about how even a million people living on Mars (as Elon Musk has envisaged) would not really make for an economy of the type we have come to enjoy on Earth.  He explains, with an example I hadn't heard of:

...in the modern world there are often huge economies of scale in production. These economies of scale make it efficient to supply the entire world market for some goods from only a handful of locations — sometimes just a single location — with international trade delivering those goods to customers in other countries.For example, a recent shortage of semiconductor chips — which seems, finally, to be easing — has drawn attention to the role of photolithography machines, which use light to etch microscopic circuits on silicon wafers. (Any sufficiently advanced technology is indistinguishable from magic.) The world market for these it turns out, is dominated by a single firm in the Netherlands, ASML, which has a complete monopoly on the latest generation of machines, which use extreme ultraviolet light to make circuits even more microscopic.

So how many factories does ASML have assembling these cutting-edge machines? One. (It has other factories producing subsystems.)

These economies of scale mean that no one country can reasonably produce the full range of goods required to operate a modern, high-technology economy. International trade is essential, and more essential the smaller the economy — which is why Canada is far more dependent on imports than the United States, Belgium far more dependent than Germany, and so on....

Now, given access to world markets, even small countries can have full access to the benefits of modern technology; life in Luxembourg is pretty good. But unless we actually invent the Epstein Drive or something, the realities of transportation costs mean that Musk’s hypothetical Mars colony would have to be largely self-sufficient, cut off from the rest of the solar system economy. And it wouldn’t have enough people to pull that off with anything like a modern standard of living.

As I said, I see Musk on Mars as a teachable moment, an unintended thought experiment that helps remind us of the positive aspects of international trade. Yes, there are downsides to globalization, especially to rapid change that can disrupt whole communities. But you really wouldn’t want to live in a world without extensive international trade. And you really, really wouldn’t want to live on another planet, cut off from the globalization we’ve created on this one.
