Lucas,
this article, which my wife came across some days ago, may provide some inspiration on (re)building with locally available materials.

So Haiti has oil ... lots of it, it seems.
The US wants that oil and is maneuvering their troops into place to occupy the spot where that oil is hidden in the ground.
The first question to ask ourselves: Is the US doing this unilaterally or in con…
Yes, the price is a sticky point of that filter.
Thanks for the references to siphon filters and local chlorine manufacture.
It is interesting, but very expensive. The Lifesaver bottle costs US$150+shipping and filters 4000 litres of water (1). This means that it costs about 3.75 cent/litre. Compare that to to the US$10 Siphon filter (2), which filters 7000 litres before…
Michael Pritchard's water filter turns filthy water drinkable

I believe it is a matter of incremental steps that end up where you describe - killing is good because it brings balance.
In an undisturbed state, Nature is in balance. Part of that balance is killing, as animals higher on the food chain kill and d…

- With friends I individuated areas in our civilization that need urgent change, and those are the things I work on. Not a formal project, to be sure, but it is an outline that gives direction to what I have been doing since the 80s now - for a good 20 years.
The outline of areas to change and roughly what direction we should be going in, is at
Genova, the Azores and our Common Future
- Where are you located? (if you know LAT/LONG we will put this on a map later)
- Rome, Italy most of the time,
Terceira island, Azores, some months each year.
- What specific skills, technologies or connections you would like to find among the Global Swadeshi Network members?
- A spread of every skill, technology and connection - the broader the better.
About that power plant ...
Here is the concrete structure of the vortex-forming basin without the turbine/generator. You can see the overflow and the very low head (altitude differential) needed for this type of plant.
And here a picture of the vortex actually driving a slow moving turbine (the turbine blades are made from simple bent metal sheets). Fish love it, because they can pass right through.

NEGATIVE ENTROPY AND SUSTAINABILITY
I am putting this article by T. Vijayendra here not because it is of immediate concern for swadeshi, but because I just read it and want to keep it available.
In one of my early articles, A New Beginning For Thermodynamics, I argued that the second law of thermodynamics is not a final reality, but that there is a reverse force to entropy which complements it. Buckminster Fuller called that reverse entropy 'syntropy', and Viktor Schau… Continue

- Hi :) The site is actually not up and running yet! It will be soon - I´m writing my thesis right now so everything else is unfortunately less important!

- Thank you for the link to Chris Cook's work. I have compared systems with Chris back as far as the Omydiar Network and later on Ned.
"A new generation of direct "Peer to Peer" investment in Units of production or revenues from productive assets"
is very close to the idea. Chris does not have a sense of economies of integration or a focus on basics (food, clothing, shelter, education and health care) to be consumed by the owners, but the underlying transaction has the co-ownership characteristics.

When you have the time...David Braden is helping me, rewriting my confusing english.... and publish it. It is a project to give the fishing pole instead of the fish... and we have the resources.

- Yes, I am considering attending this year. Michael Maranda, Ted Ernst and I are trustees for the Emerging Futures Network - no current activity because we couldn't get consensus on how to proceed - but we still keep in touch.

Did you see my explanation of the valve on the organic digester?
It is very clever, no mechanical valves at all.
