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
Building a biological DIY greywater system (with no reedbeds) October 16, 2012 | Natural Building, Water Harvesting + Reuse | 37 Comments | Author: Kirsten Bradley 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. What Ross suggested was a very simple system. >> More posts on appropriate technology
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.

How To Build A Greywater Filter For $30 Or Less My wife, of course, likes to take baths. My son is afraid of the shower so he takes baths. I try to conserve water wherever I can and even take a 5 Gallon Bucket into the shower with me to collect the water when it’s heating up, and while I’m lathering up (5th paragraph down in the post). In a way I am a bit hypocritical in the sense that I have a pool, and pools aren’t eco-friendly or promote water conservation. I’ve been trying to think of ways to offset the extra consumption of water due to the pool – which leads me back to the bath water. Our entire yard was cemented over a long time ago. I bought a 5.5GPM pump a while back from a used electronics store and I have lots of marine batteries to hook it up to. 5 gallon bucket – can be bought at a hardware store for under $5, but most people already have one laying around a 1 1/2″ pipe connector – male and female – for the drain hole. Here are the step-by-step pictures of the project as I constructed the filter. The parts list Pinterest
The Future Looks Bright: Energy-Efficient Lighting Technologies | Sponsored by Engineered Lighting Products, Journée Lighting, Kim Lighting, and WattStopper | Originally published in the September/October 2010 issue of GreenSource | Architectural Record's New advances in controls, fixtures, lamps and more help reduce energy costs and environmental impact. September 2010 By C.C. Sullivan Codes for Smarter Buildings Beyond today's flexible, easy-to-use control systems, energy codes are driving the adoption of intelligent lighting, says Pete J. "State energy codes require efficient lighting sources measured in watts per square foot, automatic shutoff, usually an occupancy sensor or timer, manual on-off control, and multilevel lighting control," Horton adds. Other codes and standards driving the industry toward energy-efficient lighting and daylighting include the new LEED Version 3, which outlines a provision for lighting controls that enable occupant adjustments to meet both individual and group preferences. It's more than codes, of course, pushing project teams to focus on illumination. Application is Everything The big question is how to maximize resources, minimize upfront costs and optimize energy use.
