Modern unicorns part two: Nuclear Fusion
It’s a truism that nearly all the news about real life is bad these days. As if to compensate, the media seem to be turning in desperation to increasingly speculative subject matter, presumably in an attempt to boost morale and have something positive to talk about.
In my last post I referenced the stream of stories about Martian colonisation plans which currently infest the popular media. In this post I will cover the other ‘positive science news story’ that virtually every periodical (or at least, all the ones that feature in Google News) is now pushing, namely nuclear fusion.
The line that perennially introduces the subject of fusion power is that it is ‘thirty years away’, in fact it has been thirty years away for the whole of my adult life. It has also been the subject of constant reinterpretation and misinformation, a prime example being the fallacies perpetrated by the advocates of so-called cold fusion in the late 1980’s. Fusion has a tendency to lie low for decades, but like Dracula rising from his grave, will always return when least expected, or wanted.
One of those times is now…
The current attempts to develop nuclear fusion as a ‘reliable power source’, are characterised by the following; on the one hand, vast amounts of money spent by Governments who really ought to know better, building huge white elephant projects that suck in huge amounts of energy (as well as cash), without giving anything back. On the other, lone ‘geniuses’ working small-scale projects in obscure research institutions, making the same sort of extravagant claims as the proponents of cold fusion. The result is always the same; at best, fusion that lasts for nanoseconds and no prospect of anything approaching commercially-viable electricity generation.
One side side of me (the Romantic side) hopes that I’m wrong and one these lone geniuses will get it right, the rational side knows this a chimera, and the lone geniuses are in fact the modern equivalent of Medieval alchemists, doomed to spend their lives trying to transmute their base metal into gold.
The fact that any of this gets house room, let alone endless column inches promoting highly-speculative claims, tells us rather more about our current society than the credibility of the fusion lobby.
It tells us we have an obsession with the notion of genius, and of genius (sic) solutions. These are often promoted as hacks (or tricks), i.e. shortcuts that will enable us to solve difficult and intractable problems. As such, they appeal strongly to generations with limited patience and rather short attention spans.
Even a cursory reading of history tells us that these sorts of attitudes have prevailed in the past, usually in times of rapid technological change (the 1880’s and 90’s spring to mind), when even the highly-educated begin to lose track of the giddying pace of change and start to see science as a source of magical solutions. This particular zeitgeist is, of course, ripe for exploitation by charlatans.
There are however, underlying all of this, some even more fundamental notions:
1, that more tech is the solution to everything
2, that technology is always the solution to existing problems, never the cause of fresh ones
3, that endless economic growth is both possible and desirable
Recent history gives the lie to the first two; one only has to look at the intractable problem of storing the by-products of nuclear fission, waste that will remain deadly for thousands of years; at the non-biodegradable plastics filling our oceans; and to the dangerous climate change being unleashed by releasing millions of years of stored carbon through the burning of oil and gas.
The fallacies inherent in the last statement are nicely illustrated by the recent claim that ‘a population of trillions can be supported off-world by exploiting the resources of the Asteroid Belt!’
When it comes down to it, this guff is ideological and quasi-religious; advocated by people who propose spreading the Abrahamic notions of the Old Testament (‘…thou shalt have dominion over the Earth’, etc) throughout our Solar System and beyond.
As, like a plague of technological locusts, we seek to consume and destroy everything within our reach.
