Knowledge, technology, and the politics of rice

by

The dominant focus on advanced technologies and higher-level politics, I argue here, has limited value for understanding crucial elements in processes of technological change that take place in society, therewith touching upon key democratic values. This is illustrated with introduced changes to rice cultivation. Technological change is often associated with innovation.

China Coal Update

by

World coal production and consumption data for 2011 are not yet compiled and published, but one key number is in. China’s Ministry of Industry and Information Technology reports that the country’s coal output rose 8.7 percent from 2010 to reach 3.88 billion short tons last year. For comparison, US consumption in 2010 was just over 1 billion tons—and holding steady (mostly due to cheap natural gas prices). If the current trend continues, China will burn well over 4 billion tons of coal in 2012, four times as much as the US.

Sanity checking an energy improvement proposal (I)

by

A few weeks back, I mentioned that I had an energy audit performed on my family’s home (a nineteenth century farmhouse on a stone basement in upstate New York, which we moved into last year). I outlined the findings and the proposals that my local energy efficiency contractor had suggested.

Since it’s a large commitment I set out to build my own model of the thermal performance of our house in a spreadsheet to make sure I believed in the improvements. In this post I am going to outline this model for the house as it functions at present. Then in a second post I will take up what the proposed improvements might do, and how the finances might work out.

Review: Petroplague by Amy Rogers

by

We have a brand-new entrant to the oil-eating-bug-runs-amok tradition: the self-published novel Petroplague. It’s a Crichton-esque thriller written by microbiology professor-turned author Amy Rogers, who says she aims to “blur the line between fact and fiction so well that you need a Ph.D. to figure out where one ends and the other begins.” The plot involves a batch of experimental, oil-hungry bacteria inadvertently loosed upon Los Angeles, which proceed to wreak a near biblical swath of destruction. Part ecology lesson and part cautionary tale, Petroplague is an entertaining entrée into the subject of oil depletion and its implications for society, human health and the environment.

Goodby Supermarkets!

by

Today, in Lewes, we spend about fifty million pounds a year on food and drink and most of that – at least forty million – is spent in our three supermarkets: Tesco, Waitrose and Aldi. In those hundred years – and especially the last fifty years since I was born – we’ve managed to let all this natural capital be diverted into the hands of a few multinational corporations. Our local food economies have dried up; local money no longer circulates around and about the town, building wealth and relationships as it goes. A tenner spent locally multiplies many times over as it circulates. Spent in a supermarket, that tenner goes straight out of town and into the hands of Tesco and co, and its shareholders.
