The Sietch Blog » Watercone – An Ingenious Way To Turn Salt Water Into Fresh Water
The Watercone is an ingenious device that can take salty water and turn it into fresh water using only the power of the sun. The nice thing about this device is it is bone simple, uses the sun instead of fossil fuel, and is cheap to make and easy to use. The Watercone is surprisingly a cone, that you place over a pan of salty water (or over a marsh, or any damp ground) leave it out in the sun, water evaporates, the condensation trickles down the side of the cone, at the end of the day you flip it over, remove the cap at the top and drink the water. This device has the potential to really do a lot of good for a lot of people. They claim that on average one Watercone can produce one liter of water per-day. The Watercone website has some really interesting information and I highly recommend checking it out. 1. Related:  TutorialWater

And though we all know that such a gadget probably doesn't exist, there is a piece of equipment that comes pretty close: the hydraulic ram pump. The water ram (also known as a trompe) has been around for quite a while and was a widely used means of pumping water before electricity became common in rural areas. Although the hydro ram won't operate without a fluid power source, it will work indefinitely when water is present. It's a Bargain at 1/10 the Price... Quality hydraulic rams are available commercially for anywhere from $400 to $800, complete. Most of the components of our pump are fabricated from PVC pipe, the same conduit that's used throughout the country in residential and industrial plumbing systems. NOTE: If you wish, you may substitute Schedule 40 black pipe (of comparable dimensions) for the flexible polyethylene used at the drive and delivery ends of the system.

Waterpyramid Usage The WaterPyramid is used in tropical remote regions to desalinate saline water and to harvest rainwater. The technology is best used were abundant radiation of the sun and free ground space is available. Target groups Remote rural villages in desert areas, tropical regions and island ridges lacking sufficient fresh drinking water. Production On yearly basis approximately 600 m 3 of fresh drinking water is produced: 300 m 3 distillate and 300 m 3 as a result of rainwater harvesting. Technology: Unique and rewarded by the World Bank with the Development Marketplace Award 2006. Benefits of WaterPyramid: good quality drinking water made easily available 'low-tech', can be operated and maintained by local workforce provides income generation and work for local workforce to be applied in rural and remote situations low operational and maintenance costs proven technology More information is given here (pdf) and here for comprehensive pdf leaflet.

Desalination Desalination, desalinization, and desalinisation refer to any of several processes that remove some amount of salt and other minerals from saline water. More generally, desalination may also refer to the removal of salts and minerals,[1] as in soil desalination, which also happens to be a major issue for agricultural production.[2] Salt water is desalinated to produce fresh water suitable for human consumption or irrigation. Due to relatively high energy consumption, the costs of desalinating sea water are generally higher than the alternatives (fresh water from rivers or groundwater, water recycling and water conservation), but alternatives are not always available and rapid overdraw and depletion of reserves is a critical problem worldwide. Desalination is particularly relevant to dry countries such as Australia, which traditionally have relied on collecting rainfall behind dams to provide their drinking water supplies.

A Graphic Design Primer, Part 3: Basics of Composition Jun 27 2011 In the first two sections of this primer, we covered the basic elements of design, and the basic principles of design. In this section, we’ll cover the basic principles of composition. There are a variety of different composition theories you should familiarize yourself with. Since this is just a primer, there’s a brief overview of the most common and important theories. You’ll want to study each in more depth before putting them to use, so we’ve included some additional resources for each. Single Visual The single visual method of composition is where a single, generally striking, visual image is used as the basis of the design. The single visual pattern is the easiest composition to successfully achieve. Sites like those created on are a great example of the single-visual composition pattern. Jamie Brown’s website has a similar single visual design: The Divine Proportion The Rule of Thirds Resources: Focal Point Think carefully about what your focal point will be. Closure
