Prog rock epiphany

Over at Slate, Dave Weigel has a series on progressive rock for which he admits a fondness, while quoting a description of it as the “single most deplored genre of postwar pop music.”. Thanks to the playing of Mike Oldfield’s Tubular Bells at the Olympics opening ceremony, there’s even talk of a revival. As it happens, this album played a significant role in my life – in fact, it was something of an epiphany, which changed my views on all kinds of things, though not in the same way as for Weigel.

This boy will go far

At what appears to be a tender age, UQ Union President Colin Finke has perfected the art of the non-denial denial. Responding by email to a question from the Brisbane Times about the exclusion of all opposition parties from the Union elections (their names having been registered by Finke’s cronies), Finke stated

“These accusations are completely incorrect,”

“My understanding is that the returning officer [gym manager Alexa Faros-Dowling], an independent officer overseeing the UQ Union elections, has informed students that there are a number of registered parties running in the union elections.

“This attack appears to be no more than petty student politicking.”

It will be fascinating to watch Finke’s LNP career.

Singularity review repost

The discussion of my repost on the silliness of generational tropes produced a surprising amount of agreement on the main point, then a lot of disagreement on the question of technological progress. So, I thought I’d continue reprising my greatest hits with this review of Kurzweil’s singularity post, which I put up in draft from at Crooked Timber and my own blog, producing lots of interesting discussion.  Again, seven years old, but I don’t see the need to change much – YMMV

How to solve the solar storage problem

Australians installed more domestic rooftop solar PV in 2011 than in any other country in the world. Despite sharp cuts in subsidies, that seems likely to continue, and raises the question of how this will effect patterns of electricity demand and in particular the capacity of the electricity system to meet peak demand. I just ran across an interesting infographic prepared by a consulting group called Exigency management which puts the question into sharper focus . Under current conditions, demand peaks around noon, remains high through the afternoon, then has another peak in the early evening, as people come home and turn on airconditioning or heating. Widespread takeup of home solar PV will increase supply at the noon peak and even more in the afternoon, but drop off as evening approaches. The result, in the absence of any other changes, will be a system with a demand trough in mid-afternoon followed by a much sharper evening peak.

What can be done about this? The first point to observe is that the demand projection is under current pricing rules. Any sensible system, faced with a demand pattern like this would set peak prices to cover the actual demand peak, not the one that prevailed under a 20th century coal-based system. But, price incentives alone aren’t satisfactory in the absence of some way of storing energy. There’s been lots of discussion of more-or-less exotic solutions, but there’s a much simpler answer.

Student union skullduggery

Student politics has long been the playground of budding party apparatchiks keen to try out dirty tricks, but the current Union election at hte University of Queensland goes beyond anything I’ve been seen before. I expect that, when these hacks graduate to adult politics, they’ll make the headlines in due course, and not in a good way.

Maintenance and champerty

Those are the marvellous names for the old common law offences/torts involved in persuading others to engage in a lawsuit for your own benefit (feel free to state more precisely, IANAL).  They’ve mostly been abolished now, which is probably a good thing in terms of alllowing class actions and similar, and they’ve never applied (AFAIK) in international law.

Nevertheless, a reminder of the reason such laws existed has come with the announcement of a WTO complaint by Ukraine against Australia’s plain packaging laws for cigarettes.

Disappearing Arctic Ice

It looks as if 2012 will set a new record low for Arctic ice extent[1]. As a measure of the impact of global warming, this is depressingly clear-cut. There’s no need to go into arguments about trends and variability, or use any kind of modelling – the ice is melting visibly.

fn1. Satellite data on ice extent goes back to 1979. There are other measures, arguably more relevant, such as estimates of ice volume, for which the data set is shorter. They tell an even gloomier stories.
