Computing in the Long Emergency

by

Where will computing go in the coming years? I thought I should find out, so I watched a roundtable and other talks and interviews on the subject (warning: it’s pretty dry stuff). I came away underwhelmed. I struggled to figure out what these guys were seeing that I wasn’t. I’m not sure I’ve figured it out. Eventually I came back to the one key issue that’s missing from their roundtable conversation—and that of most conversations among engineers in the computing world—limits, both ecological and material.

Bark of popple, twig of willow: In the woods in winter

by

I should be in the woods at this time of year. Instead, because of the unusually warm winter and heavy rains that have left the ground saturated and soggy, rather than frozen and covered with snow, and because I managed to do something to my shoulder chopping wood. (I turn forty this summer, and my assumption is that the two different minor injuries I sustained in about two weeks were the official “the warranty on your body has expired and it will all go to hell now” notice.) I mostly haven’t been, but they call me. This is the season of trees on a farm.

At last, the plowgirl has arrived

by

The most obvious and promising sign of the new agriculture is the leadership that women are taking in the movement. Women have always played the key role in farming but at least in the last two centuries in America, they have rarely gotten credit for it.

Enemies of the State

by

As long as we allow proponents of unconventional oil and gas to claim a false choice between energy and economic security and the environment, and as long as we allow them to vilify opponents as being somehow unpatriotic or radical, we run the very real risk of losing a battle where the future of our planet and species is at stake. Ok, so maybe I am being a little bombastic. But am I wrong?

 

Nuclear Fusion

by

Ah, fusion. Long promised, both on Do the Math and in real life, fusion is regarded as the ultimate power source—the holy grail—the “arrival” of the human species. Talk of fusion conjures visions of green fields and rainbows and bunny rabbits–and a unicorn too, I hear. But I strike too harsh a tone in my jest. Fusion is indeed a stunningly potent source of energy that falls firmly on the reality side of the science fiction divide—unlike unicorns. Indeed, fusion has been achieved (sub break-even) in the lab, and in the deadliest of bombs. On the flip side, fusion has been actively pursued as the heir-apparent of nuclear fission for over 60 years. We are still decades away from realizing the dream, causing many to wonder exactly what kind of “dream” this is.

My prices are not too high: A farmer fires back

by

Every week during the growing season, my husband and I cart our family’s grassfed meats to market. We sell pork chops for $11 a pound; ground beef goes for $7.50. Every week, we meet someone who tells us the prices are too high. In fact, at those prices, the average net income for our family members has maxed out at $10 per hour. But part of our job is to hold our chins up and accept weekly admonishment for our inability to produce food as cheaply as it can be found in the grocery store.

Peak kitsch: “The Crisis of Civilization”

by

And, as we’re always saying here at Transition Voice, however compelling evidence may be in a white paper, chart, graph, or long lecture, if it doesn’t succeed in communicating the problem and possible solutions to the problem in a way that engages people, it can end up being of little use except in obscure research or as a footnote somewhere. That’s why we were excited to review a new documentary out of the UK, The Crisis of Civilization, by filmmaker Dean Puckett. In the trailer it looked like the newest, most accessible peak oil film since The End of Suburbia. And once we watched the film, we weren’t disappointed.

connecting with our roots – a plants for life talk

by

But to connect with the plants is to connect with the rhythm of the year, to locate yourself in time and space. It is to connect with the neighbourhood you find yourself in and discover, that even though your world has apparently shrunk because of economics and peak oil, it has in fact grown hugely. It has by your attention to detail, brought memory, fragrance, belonging back into your life, as you notice the limes in the churchyard, the sage in the library garden, the butterburr along the highway. Each plant a small universe with its own story to tell, its own medicine to bequeath.

Resilient people, resilient planet: a future worth choosing

by

Now more than ever, leaders need to focus on what matters most – the long-term resilience of people and the planet – the High-level Panel on Global Sustainability urged in its report presented today to UN Secretary-General BAN Ki-moon in Addis Ababa.

The 22-member Panel, established by the Secretary-General in August 2010 to formulate a new blueprint for sustainable development and low-carbon prosperity, was co-chaired by the presidents of Finland and South Africa. The final report contains 56 recommendations to put sustainable development into practice and to mainstream it into economic policy as quickly as possible.

The hydrogen dream

by

Cesare Marchetti proposed hydrogen (H2) as a large-scale energy vector almost fifty years ago. The main concern then was to find a simple way to feed transport systems with what seemed to be a fountain of energy about to come from the expanding nuclear park. The nuclear dream is largely gone, but hydrogen lives on. Is this dream about to come true as a piece in the transition puzzle to a post-fossil fuel world? That’s what I was expecting to find out at a renewable energy / efficiency conference the University of Lorrain.
