WATER FOR LIFE

The Australian National University (ANU) scientist Tony Flynn has developed a process to create water filters from commonly available materials. The materials need to also be fired, which can be done without a kiln or other western technology, by using common manure.

An estimated 80% of all sickness in this world can be attributed to unsafe water and sanitation according to the World Health Organization (WHO). That can be seen in the annual 1.5 billion episodes of diarrhea in children under the age of 5, with about four million of those being fatal.

Since historically water filters have had to be imported to developing nations, which means increased cost and reduced availability for the populace. With the new filter design made from common place materials available in even the most remote places.

“These filters are a hollow ceramic vessel filled with charcoal. They are intended to filter out suspended silt and bacteria. However, at around $US5 each, they’re too expensive for individuals in many developing communities to consider purchasing,” stated Mr Flynn. “They are very simple to explain and demonstrate and can be made by anyone, anywhere. They don’t require any Western technology. All you need is terracotta clay, some used coffee grounds or tea leaves, a compliant cow and a match,” Mr Flynn continued “Everyone has a right to clean water, these filters have the potential to enable anyone in the world to drink water safely.”

Filter production is simple:

• A handful of crushed dry clay
• A handful of common organic material, such as coffee grounds, rice hulls, or used tea leaves
• Add water, just enough to make a stiff biscuit dough like mixture
• Shape into a cylinder shaped pot closed on one end
• Dry it in sun
• Place dried filter on a layer of dry manure, a little straw, dead leaves or shredded bark
• Add two more layers of manure mixture on top
• Light the straw, dead leaves, or shredder bark
• Keep fire going until pot is completely cured (less than an hour in most cases, as different materials will mean different times)

Since using a potters kiln can take up to eight to nine hours to achieve the temperatures needed, which can be achieved using this method in a hour or less. Also with the expensive of such a kiln being prohibitive to most people, this is an excellent method anyone can make use of. Especially since no additional technology, or added insulation is needed being able to drink safe, filtered water water in almost any location on the planet. As long as water, manure, red/yellow clay and human organic debris you can make a filter that traps pathogens.

This design is purposely not being patented in a hope that it can be freely used around the world. Their belief that even third world countries should have the ability to have clean safe drinking water.

Being tankless in heating your water is an easy, if somewhat costly, upgrade that you can see immediate benefits from. Costs can vary from about $150 for point of use water heater to household ones starting about $450 going up to $1000 or more for top of the line models. Point of use models install directly under the water fixture which also means less heat loss and you can convert your water heating system slowly one water fixture at a time. But since most houses have at least two sink and a tub you will already go over the cost of the cheapest whole house tankless system. On the plus the up front cost can be spread out over time, and for smaller places such as boats, RV’s, campers, etc. it might just be what you are looking for.

The average household spends $50 or more a month just to keep hot water at the ready. This means that the hot water is heated and then stored in it’s tank to wait for use. Just like anything else that id hot and left to sit heat loss happens and then it needs to be re-heated, which just starts the cycle over again. Once the water is used the cycle is again in place till that water is used, and so on. That is a lot of wasted energy you are paying for just to have the convenience of on demand hot water. At that hot water is finite since the average tank system holds about 40 galleons and tankless can supply an infinite supply. Chyanging over to a tankless system lets you use as little or as much hot water as you need without the worry over running out or heating more than needed.

The lifespan of a tankless water heater, 20+ years, is almost double that of a convential water heater, 8 to 12 years, Also a tankless system is serviceable while most tank water systems are not. Tankless systems also can be installed outside your home or in a fraction of the space vacated by your convetnional one. It’s almost like adding a small closet to your home of usable square footage.

The conventional water heater is only about 40% to 60% energy efficient do to the heat loss through the exhaust and the walls of the tank. While tankless are 60% efficient for the gas version and 99% efficient for the electric version. So for those of you who have or are looking to change to personal energy systems this is one less drain of your limited energy production without lossing the comfort of hot water on demand.

For those who use radiant heat, tankless systems can work for you too., They can be installed in RV’s boats,mobile homes, sheds, barns, etc. So the applications seem almost endless for anyplace you need/want on demand hot water production. …
