The World’s First Post-Growth Economy

February 1, 2011 by kris de decker Filed Under: Economy

Japan economic growth “One of the problems with the post-growth movement is that it can appear theoretical. No matter how confident we might be, we lack proof that a post-growth economy is possible. Or do we? Perhaps the world already has a post-growth society, albeit an unintentional one. Here’s what Japan’s GDP has been up to for the last twenty years.”

“As far as economists are concerned, this is a tragedy and a disaster. And yet, the lights are still on, everything still works. Literacy is high, and crime is low. Life expectancy is better than almost anywhere on earth – 82 years to the US’ 78. The trains run to the second. Unemployment is only 5%, and levels of inequality are enviable. So maybe Japan isn’t a failure. Maybe it’s just ahead of its time – not ‘stagnating’, but settling into the plateau of ‘enough’.” Read.

How to Build an Earthbag Dome

“Domes are the strongest form in nature and easily support enormous forces. They create the most floor space for a given length of wall. There are no wasted corners. The feeling inside is magical. Those who live in domes (and roundhouses) most likely never live in boxes again. Wind flows around domes and does not build up pressure against them.”

“You can build domes without wood. You can build domes with minimal tools and materials – no nails, no wood, no plywood, no shingles. This makes domes a good candidate for those who lack carpentry skills and for emergency shelters for disaster areas and war refugees. Give people some rice or grain bags and a little training, and soon they can build their own sturdy, safe shelters.”

National Guard troops operating a remote video surveillance system at the Naco Border Patrol Station say they observed several people preparing a catapult and launching packages over the International Border fence last Friday evening.” Read & watch.

Judging Technology

January 28, 2011 by kris de decker Filed Under: Technology

Ran Prieur started an interesting initiative: TechJudge, in which a rating system is applied to different technologies.

“In this age, ‘judging technology’ means one of two things: reviewing a particular tool for how well it satisfies the consumer, or doing deep thinking about Technology as a whole. I don’t think there’s any such thing as ‘technology’. Every tool, every system of tools, every use of every system of tools, is a different animal. And instead of judging a clothes dryer for how well it dries your clothes compared to another clothes dryer, we should also judge it for how it affects the meaningfulness of your life, the society it is part of, and the rest of life on this planet. The goal of this page is to inspire deep thinking about particular technologies.”

For now, only the transportation section has been (partly) filled in. The “passenger dragon” (which scores the maximum of 100 points) left me a bit confused, but here are the preliminary results for the more common transport means:

  • sailboat 85 – 74,
  • horse 79 – 70
  • bicycle 77 – 63
  • private jet 58
  • airliner 45
  • passenger train 44 – 30
  • automobile 25

Note that energy use and ecological damage are not the only criteria.
