Why energy storage is a solvable problem

by John Q on January 12, 2022

Most discussion of energy storage that I’ve seen has focused on batteries, with occasional mentions of pumped hydro. But in the last week, I’ve seen announcements of big investments in quite different technologies. Goldman Sachs just put $250 million ($US, I think) into a firm that claims to worked out the bugs that have prevented the use of compressed air storage until now

And several companies are working on gravity storage (raising and lowering massive blocks) to store and release energy

Underlying these points is a crucial fact in physics/engineering: Any reversible physical process is an energy storage technology.

That’s why concerns about the variability of wind and solar power will come to nothing in the end

In defense of presentism

by John Q on January 9, 2022

I was planning a post with this title, but after some preliminary discussion, a commenter on Twitter pointed me to this piece by David Armitage, which not only has the title I planned to use[1], but a much more complete and nuanced presentation of the argument, as you might expect from the chair of the Harvard history department.

I won’t recapitulate his points, except to make an observation about disciplinary differences. The dominant view in history described by Armitage as “professional creed: the commitment to separate the concerns of the present from the scientific treatment of the past” is identical, with a slight change in terminology, to the central claim of “value-free economics”, that it is possible to separate the positive science of economics, from the normative question of what economic choices should be made. [2]

What’s striking here is that the idea of “value free” economics has been the subject of severe criticism for decades, starting in the 1950s with Gunnar Myrdal [3]. Hardly anyone now puts forward claims of this kind in the strong version presented most notably by Milton Friedman. This view is routinely denounced as a residue of “logical positivism”, an pejorative with much the same valence as “Whig history”, except for a reversal of sign.

Armitage’s defense of presentism runs along very similar lines to the critiques of value free economics. Most notably, he observes

can we plausibly deny that we choose our subjects according to our own present concerns and then bring our immediate analytical frameworks to bear upon them?

Referring to history specifically, he says

only history—again, only our individual experiences and that collective record of the human past in all its forms, from the cultural to the cosmic—can supply the information and the imagination to shape our choices, in the present, among multiple potential paths into the future. If historians too freely use presentism as a slur or as a taboo, then we may be guilty of depriving our readers, and indeed ourselves, of one valuable resource for promoting human flourishing: history.

Myths that stir trouble in the South China Sea

by John Q on January 5, 2022

Just before Christmas, I published a piece in The Interpreter (Lowy Institute) arguing that most of the claims made by the contending parties in the South China Sea are myths designed to promote the interests of nationalists and militarists in a variety of countries, including Australia. Final paras

The mutual sabre-rattling associated with South China Sea mythology is beneficial to a variety of actors in the United States, China and elsewhere. The military-industrial complex, against which President Eisenhower warned 60 years ago, is powerful in every country, and always seeks to promote preparation for large-scale war as well as the routine use of military power for political and commercial ends. Nationalist politicians promote territorial claims of all kinds, and exaggerate their importance. And both Chinese and Taiwanese governments have good reasons to keep the idea of an invasion of Taiwan alive.

Unfortunately, these myths are not harmless. The possibility that the United States and China will somehow blunder into war is ever-present. And if such a war broke out, Australia would have a choice of bad options: either a disastrous war with its biggest trading partner or a breach with its most important ally. Rather than joining the alarmist chorus, the government should be seeking to reduce tensions.

The week before Christmas is traditionally a time to publish for those who want to avoid attention, so my timing wasn’t ideal. But in the New Year there has been a bit more interest. I was interviewed by CNBC Asia and Radio Free Asia, and there have been a few republications/

Getting it wrong on the future of democracy?

by John Q on December 21, 2021

As I indicated in my previous post about self-driving vehicles, I’m trying to think more about where I’ve gone wrong in my analysis of current issues and trends, hoping to improve. I got some useful comments on that issue, though nothing directly applicable to my bigger predictive failures

The most important such failure has concerned the future of democracy, where my views were characterized by clearly unjustifiable optimism (see here and here). I’ve now shifted to extreme pessimism, but I would love to be convinced I’ve overcorrected, as I have done in the past.

Getting it wrong on self-driving vehicles

by John Q on December 9, 2021

A few years ago, I got enthusiastic about the prospects for self-driving vehicles, and wrote a couple of posts on the topic. It’s now clear that this was massively premature, as many of the commenters on my post argued. So, I thought it would be good to consider where and why I went wrong on this relatively unimportant issue, in the hopes of improving my thinking more generally.

The first thing I got wrong was overcorrecting on an argument I’d made for a long time, about the difference between radical progress in information and communications technology and stagnation in transport technology. The initial successful trials of self-driving vehicles in desert locations led me to think that ICT had finally come to transport, when in fact only the easiest part of the problem was solved.

There was also an element of wishful thinking. As commenter Hidari observed, the most obvious use of self-driving vehicles is to provide mobility for 75+ Baby Boomers. As someone approaching that category, and having never liked driving much, this is an appealing prospect for me. And I liked the idea of taking other bad drivers’ hands off the steering wheel.

That framing of the issue is very different from the way a lot of commenters saw it. Should self-driving cars be seen as automated taxis, and if so is automation desirable or not? Is any improvement in car technology a distraction from the need to shift away from cars altogether? I don’t have good answers to these questions, but they indicate that resistance to self-driving cars won’t be purely a matter of technological judgement.

Finally, having put forward a position, I am usually tenacious in defending it. Within limits, that’s a good thing, particularly in the context of a blog where the discussion doesn’t have any direct implications for what happens in the world. It’s good to put up the strongest case, and test it against all counter-arguments. But that approach carries the risk of being obstinately wrong.

I’m hoping discussion here will help me deal with more consequential errors of judgement I’ve made. So feel free either to discuss the original question of self-driving vehicles or the broader issue of how to think about mistakes, and particularly mistakes I’ve made.

The case for being born

by John Q on November 28, 2021

The New Yorker is running a profile of the anti-natalist philosopher David Benatar. Reading it, I was unconvinced by the implied response to the obvious objection, “if life is so bad, why not kill yourself”, namely that suicide is painful in itself and causes pain to others.

I searched a bit, and discovered that, not only had Harry covered the book here soon after it came out, but I had made the same objection in comments[1], which I’ll reproduce for convenience

given that Benatar is arguing from a utilitarian rational choice position, his argument leads straight to the (more or less standard utilitarian) conclusion that there should be no moral weight attached to suicide. That is, people should commit suicide if they reasonably judge that their future pains outweigh their future pleasures. Sympathetic others should not deplore the fact of suicide (though they should be saddened by the facts leading to the decision).

Once that position is established there’s no problem bringing new people into the world. If they don’t like it they can always kill themselves. That, it seems to me, is orthodox utilitarianism, with a bit of a helping hand from revealed preference.

Of course, this kind of thing is all very well in a philosophy class. In reality, suicide is more commonly the result of momentary despair and is a tragedy for both the person concerned and their friends and family.

Since 2008, most Australian states have introduced assisted dying laws, which seem to strengthen the case against Benatar’s claim (at least as applied to Australians). People who face suffering that outweighs any future pleasure can end their lives painlessly and without causing harm to their loved ones (most people who have faced the painful death of loved ones supported the legislation).

It’s true that this option is only available to the terminally ill (12 months to live), but there was no apparent demand for broader access, and the number of people taking the option has remained small.

So, if painless suicide is possible, and those who care about us should (and mostly will) support our choices if life seems unbearable on careful reflection, Benatar just seems to be saying that we are all making the wrong choice in staying alive. How (except in the extreme nature of his suggestion) does this differ from someone saying we are all wrong in our choices of food, music, life partners etc and would be truly happy if we only ate food listened to music, and shared our lives with people we hated?

fn1. This happens to me a lot, either because of failing memory or excessive opinionating.

Thinking the unthinkable

by John Q on October 27, 2021

If the last five years have taught us anything it’s this: the fact that something being unimaginable doesn’t mean it isn’t going to happen. So, it’s worth considering the prospect that Donald Trump becomes President after the 2024 election whether by getting enough votes to win the Electoral College under the current rules, or by having a Democratic victory overturned. Trump has made it clear that, in such an event, he would wish to secure at least a third term in office and perhaps a life presidency.

How big a bubble ?

by John Q on October 4, 2021

We[1] are often urged to “get out of our bubbles” and engage with a wider range of viewpoints. As Chris said here, this mostly turns out to be a waste of time. As I experienced from my side, engagement with the political right consists mainly of responding to a string of talking points and whataboutery, with little if any content. On the rare occasions these discussions have been useful, it’s typically because the other party in the discussion is on the verge of breaking with the right[2]

To restate the case in favour of getting out of the bubble, it’s easy to see examples of people on the left putting forward arguments that don’t stand up under criticism, but haven’t faced such criticism within the limited circles in which they’ve been discussed. But the most effective criticisms of such arguments is likely to come from people with broadly similar political aims and understandings.

As Daniel once observed, opinion at CT runs the gamut from social democrat to democratic socialist, and I have traversed that range in both directions. I get plenty of benefit from arguing with other people in that range and with some a little outside it, such as liberaltarians and (not too dogmatic) Marxists.

Opening up the discussion bubble now.

fn1. At least we on the left, I rarely run across this suggestion in the rightwing media I read.
fn2. TBC, I don’t think the powerful force of my arguments has converted them; rather it’s that people making this kind of shift often have interesting things to say,

The Scrooge McDuck theory of the rich

by John Q on September 25, 2021

Readers of a certain age will remember Scrooge McDuck, the mega-rich uncle of Donald, who enjoys diving into his gigantic money bin filled with gold coins. Replace gold with paper currency[1] and you have the archetypal version of a theory of the rich [2] popular in some versions of Modern Monetary Theory.
