Today the Hexayurt was on the front page of Wired.com. (Right under "The Steve").

Looking at the comments in that thread one wonders why large scale media like NYT or Wired has comment capabilitie…
In all practicality, until you can take one of the final design Hexayurts down to the University of Florida and actually prove that the structure can withstand the forces of a hurricane, no one will take this design seriously.
I am somewhat puzzled…
Just a note. Akvo.org is not really set up for emergency fund raising. We neither have the audience nor the connections to do this in a productive manner. Besides, we haven't started to do stuff outside of water and sanitation yet.
In my view, ther…
Sodis is fairly well documented, and as far as I can tell it is effective against viruses too. What makes you say it would not be effective against virus omdesign?

The main critic against it I have heard ha…
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…
This post is actually filled. But we are always looking for good Django folks for future work.
Was going to write something about filters and the Akvopedia, and then I noticed where the link went to. You are ahead of me sir! :)
Looking forward to participate in this at some level myself, as this is something we jointly need. The mobile site for a wiki shouldn't be to hard either, as Wikipedia seems to have shown the way there recently. More of time and resource constraint…

BTW: how do you "infrastructure for the experts to thrive." ...seems no easy task.

- negiliblek,
Actually I am no expert at all. I just provide infrastructure for the experts to thrive.
What is the best solution I would say it depends on your context and initial conditions. We have the newly relaunched Akvopedia Sanitation portal, which contains state of the art content which is possibly the best in the field. It should allow you to select what works best.
Check it out at: http://www.akvo.org/wiki/index.php/Portal:Sanitation

- Hello Thomas,
I'm about to ask you a question I could find myself over time, but, as an expert, you could get me from A to Z a lot faster -or at least from A to Q.
Which model do you find the best for sanitation?
Method I
-> urine separation -> add water -> fertilize food plants
-> solids separation -> compost
Method II
whole human waste->tank w/snails->tank w/fish+snails.->pond 1 with more cleansing organisms->pond 2 with more cleansing organisms->final running stream with pottable water out.
Method III
whole human waste->dry->burn for energy
If you want a scale, say 7 to 30 people.
If you'd like, please let me know your reasoning to help me start thinking about items I may not have considered on my own.
Thanks

could this be of interest to you?

It's a platform where problem solvers solve problems for seekers of solutions :-) this one is about rainwater harvesting in developing countries, maybe you can help there. 15'000 USD award

- Interesting. My brother is actually a crusading water right attorney, suing polluters on behalf of public interest (and often winning). He works a lot for BayKeepers in SF and LA areas. Are you aware of OpenEverything.org?
Its an attempt by some of us to help save-the-world types understand Open Source (both the software and the process of collaborative development). We're planning a conference soon in No. Cali somewhere, if you're interested.
