Evini al. Suyu, elektriği, doğalgazı ve kanalizasyon hatlarını kesin. Barınma sisteminin ayrılmaz bir parçası olarak beraberinde taşınması gereken altyapı sistemleri olmadan bir hexayurt böyle olur.

Bunu yaparken kendi evinizi düşünmenize yardımcı olur: zihninizdeki her sistemi aşağıdaki ana hatlardan biriyle değiştirin. Sistemlerin çok büyük olduğunu unutmayın: elektrik sistemi evinizdeki kablolar veya dışarıdaki direklere dizilmemiş kablolar değildir. Elektrik santrali, devasa trafolar, yüksek voltajlı uzun mesafe hatları ve şebekeyi düzenleyen hükümetin yönleri ve tüm bu şeylerin parasını ödeyen bankacılık altyapısı.

Gelişen dünyada geleneksel yöntemlerle hizmet vermek son derece zordur. Bu satır öğelerinden bazıları pahalı görünse de, dünyadaki ilk eşdeğer hizmet altyapılarına kıyasla çok çok ucuz olduklarını unutmamak önemlidir!

Development Status

Together these systems appear to combine to provide the majority of the services provided by the pipe-and-wire infrastructure harness of a first world household for a cost in the neighbourhood of $200 per household for a relatively plush system, and a minimalist installation could be under $100 per household or less with more resource sharing.

The vast majority of the products required to put together this package are common, off-the-shelf items. However, very few if any of them have gone through the rigours of deployment in the field conditions we are talking about. The CCFL flashlights are an excellent example: available in stores for around $10, with an excellent battery life and 10,000 hour or better tubes, they appear perfect. But the are not waterproof, only water resistant.

What would the failure rate be if we deployed them in a refugee camp? Would the manufacturer - either Eveready, or the plant which makes them in China, be willing to make small design changes or product a special edition, or would we hit dead ends unless we were willing to have a custom model produced from scratch (a whole different line of business.)

My hope is that we can rely on the open source approach to solve many of these problems - that as long as all of our intellectual property is open, then domain experts can help us find answers to all the questions that come up, without feeling like they are helping a for-profit or partisan group. Free IP means freedom to participate for many people. We can give the companies who produce the products we want tweaked or improved the ideas on how to do it, and they can use them or not as they please.

My estimate is that it will take 10 to 15 years for this approach to be fully vested - tried in the field, failures identified and rectified, and technologies matured to the point where it becomes obvious to all parties that we have a scalable solution. Whole systems design is hard, and takes time, and a lot of lives are at stake.

But if we don't start now, we aren't going to have that fully finished solution 10 or 15 years down the line.

This is not to say that we could not push much harder and much faster - deploy units in the field and just see what happens, and learn by doing.

PS: the $200 number is padded for a more expensive toilet, and for a share of village-scale utilities like the one-per-village 2 kilowatt central power utility.
