A Deutschland disconnected from its Volk

As elsewhere in western Europe, the advanced liberal consumer democracies are ever more unable (politically unwilling) to implement genuine change. Deutschland’s rulers in Berlin firmly believe that techno-managerial innovation (and a hefty dose of financial risk-taking) will continue to provide cures for current ideas of what is unsustainable. As has happened time and again in Europa’s history of nations, from the mid-19th century onwards, the costs of such ‘revolutions’ will be externalised elsewhere (east and south), and the ecological sustainability that Germany’s admirable network of communes have long been admired for will remain out of reach of the country’s policy and practice.

A day in the life: further adventures at the mud hut

Now that I’m retired from the academic life — or rather, now that I’ve departed the academy in disgust and despair — I no longer spend time in my swivel chair, dispensing information on the telephone or tending to the tender young psyche of an overwrought twenty-something.

Energy concentration revisited

The difference between diffuse and concentrated energy sources, the theme of last week’s Archdruid Report post, means that some of today’s highly touted alternative energy schemes may be worth much less than currently claimed, while other technologies that receive much less attention may be the wave of the future. A closer consideration of energy concentration and its effects helps clarify which is which.

Improving the Performance of Solar Thermal Electrical Power

Solar thermal is a way of harnessing the largest source of energy available to us, so in this post I’ll have a look at the upswing in interest in the use of this technology for electricity generation in recent years and look at some of the approaches being pursued to make it economically competitive with coal fired power generation.
