Create An Off The Grid Source Of Water For any off-the-gridder or survivalist, having a safe, adequate, and reliable source of water is just about as basic as it gets. Water independence is the clear goal for all who want to be prepared for all contingencies, and digging your own well is the obvious way to set yourself up in anticipation of a time when utility companies can no longer be relied upon to supply vital services to their customers. But digging a traditional well is not the only option. There is another type of well that is perfectly capable of providing sufficient supplies of fresh, clean, potable water to meet the needs of most households, especially if at least a degree of water conservation is practiced. Even though driven-point techniques have been in use for a long time, many are still not familiar with all the particulars of this kind of well. Installing a Driven-Point Well: The Basics Once water has been found and the driving stopped, the basic structure of the driven-point well will then be in place.
Peak Oil Review - Oct 15 1. Oil and the Global Economy Oil prices jumped about two dollars on Tuesday as Turkish-Syrian tensions increased, but remained relatively steady for the rest of the week with Brent closing down $1 on Friday at $114.62 a barrel and NY down to $91.86. The IEA’s new forecast of slightly lower oil demand for 2012 and 2013 helped send prices down on Friday. The IMF now is forecasting that world economic growth will be only 3.3 percent this year and 3.6 next year, adding to the pressure. Europe continues to grapple with the Greek and Spanish debt problems amid growing concerns that another global recession is in the offing. The weekly US stocks report showed crude inventories increasing by 1.7 million barrels but product inventories falling, with gasoline inventories down by 500,000 barrels to the lowest level in four years. 2. The IEA reports that Iranian oil production has now fallen to 2.85 million b/d, the lowest in level in 23 years. 3. 4. Quote of the week
Filtre à eau japonais, filtration et dynamisation de l'eau Naturalizer Kirameki : l'eau de source volcanique au robinet Durable : pas de cartouches à changer grâce au rétronettoyageEcologique : uniquement des constituants naturels Prix juste : importation directe sans intermédiaire Sûr : fabriqué au Japon depuis 30 ans Mars 2014 : Le nouveau modèle 2014 (photo en bas sur fond bleu) possède une capacité de filtration supérieure à l'ancien, à savoir 200 000 litres, vu son volume plus important. Les photos des coupes sur l'ancien modèle sont utilisées ici à titre informatif, le principe étant identique pour le nouveau modèle. Commandes sur la Boutique Biovie. Constituants du filtre Naturalizer Kirameki Références Cristaux de Masaru Emoto La première référence provient d'une méthode d'analyse globale, proche de la cristallisation sensible, qui est l'analyse des cristaux d'eau congelés, fruit des travaux de Masaru Emoto.
Building a biological DIY greywater system (with no reedbeds) - Milkwood - Permaculture courses + skills for Real Life Our criteria for building the greywater system for the tinyhouse was pretty simple: cheap, made from readily available materials, and effective. We also wanted to use the outputs to irrigate a grove of important fruit trees, as water is very precious here, especially in a dry year. After many, many hours of research on systems involving reed beds, infiltration trenches, fancy UV zappers and all the rest, we decided, on the advice of permaculture and greywater specialist Ross Mars, to keep it simple, and let the biology do the work. To summarise the approach (and Ross Mars’ general take of domestic greywater), we decided that the intermittent trickle of water coming from our bath and shower would be best dealt with in a living and dynamic system, rather than in a series of reed beds or trenches. I should note here that our greywater output is coming from just our bath and shower, so it contains water, a little soap, and the inevitable bits that come off a human when they wash.

Harvesting energy from all forms of sunlight Polycristalline silicon wafer in photovoltaic module. (Photo: Wikipedia Commons) Chris Smith from the Naked Scientists, a British science radio show, recently spent some days in Oslo interviewing Norwegian scientists. Here he talks to Per-Anders Hansen from the Department of chemistry, University of Oslo. Per: Sunlight consists of small energy particles called photons and these can have a lot of energy like ultraviolet light or blue light or they can have medium energy like red light or visible light, or they can have very little energy like infrared or heat radiation. When these photons hit the solar cell, what they do is that they knock loose one electron and this electron can then travel around in our circuit and give us power. Chris: So if we had a way of taking some of those photons that have very high energy, and converting them into more photons at a lower energy, we could get more electrons out and therefore, the overall efficiency of the cells would be much higher. Per: Exactly.
Science/AAAS | Special Issue: Working with Waste News Water Reclamation Going Green E. Pennisi Wastewater treatment plants are revamping themselves as resource recovery operations, saving—and even producing—energy and polluting less in the process. A Better Way to Denitrify Wastewater Anammox bacteria, which convert ammonia into nitrogen gas in the absence of oxygen, could dramatically improve methods of removing ammonia from wastewater streams. Save Pave the World R. Carbon dioxide may be the ultimate industrial waste product. Getting Minds Out of the Sewer G. The aversion to excrement, which is deeply rooted in the human psyche, gets in the way of sensible solutions to recycling wastewater. Podcast
