If you're not already familiar with Low-tech Magazine [1], here's a
mini-review that might help pique your interest.

Low-tech Magazine is a collection of articles analyzing various sorts of
technologies, past and present, relative to the pursuit of a sustainable
society.  The magazine (a website, actually) attempts to dispell the myth
that newer, more complex technology is always an improvement; and to argue
that older, simpler technology is often more energy efficient, less
resource wasteful, and generally has less negative side-effects.  The
articles each review a different technology from this perspective.
Articles are categorized into three topics: (1) clever and effective
technologies from the past that may be mostly forgotten now, (2) negative
consequences of many modern "high-tech" technologies, and (3) simple,
efficient technologies that may be adopted today.

Many of the low-tech solutions covered include sometimes novel applications
of the usual power suspects: solar, wind, and hydro; and they cover
interesting mechanisms for both applying and storing power.

The magazine, led by Kris de Decker, has been online since 2007 and has
published around 12 articles each year -- so there is a lot of backlog to
browse if you haven't already started reading.  Each article has insightful
analysis backed by well researched history.  It's hard not to come away
inspired to try something out or at least to come away having learned
something very interesting.

And there are a number of topics that will be of specific interest to the
pubnix community; e.g. how to build a low-tech internet [2].

I like to think of text-based computing as a small analogy to the topics
covered by Low-tech Magazine.  There is no end to posts in gopherspace
about preferences for internet interactions using plaintext alone; and
conversely, posts about the disdain for the eye candy wasteland of the
WWW.  I doubt de Decker would cover this topic in the magazine, but I
think it's an apt, yet small, analogy.

de Decker's quest with Low-tech Magazine is also something that I imagine
aligns with the sensibilities of many people in pubnix-space.  Many modern
technologies are shoved down the planet's throat, in pursuit of maximizing
corporate profits, while utterly ignoring their negative consequences on
societies or on the environment.  de Decker aims to raise awareness of
this problem and to give life to ideas that should be considered as
sustainable alternatives.

If you look at the link below [1], you'll also find one interesting way
in which Low-tech Magazine is a champion of low-power computing.  The
website is solar-powered, running off a Olimex A20 single-board computer,
with the power coming from a photo-voltaic system on de Decker's porch.
You can see server power stats on the website, including a webpage
background that doubles as a battery charge meter.  Yes, the website
does go offline occasionally, when Barcelona gets hit by extended cloudy
weather.

If you like this website, and you have other similar non-commercial www
sites to recommend, please post about them. Or even just send me an
