Technology Vs Tradition In Water Filtration Methods

Who would have ever believed that a time would come when there were no longer enough fresh, clean water resources to hydrate the Earth's population? And who would have thought that it would happen so soon? We are now faced with seriously-dwindling freshwater sources, and those we have contain a multitude of substances that can cause sickness and death. Horror stories of the dangerous levels of arsenic, chromium, selenium, and cadmium which are found in our lakes, rivers, and groundwater should be enough to shake society to its very core. After all, pollutants such as these can cause damage to your nervous system, liver, and kidneys as well as more deadly illnesses, such as cancer.
For generations we here in the United States have counted on our municipal water systems to clean the water that flows into our homes to the standards set forth by our government. Modern science, however, is determining that the regulations don't go quite far enough when it comes to public safety. In addition, water treatment plants are another of those parts of our infrastructure that are deteriorating due to lack of proper funding. And yet, we all need water in order to stay healthy and survive. We can't help wondering what we're going to do to as we look at the bleak future this picture is painting.
The answer, of course, lies in the hands of consumers like you. If you can't trust what others are doing, you can trust yourself to find a remedy for your problem. A large variety of water purifying equipment is available that has been scaled down for home use. These devices come in numerous sizes, applications, and types of filtration to meet the needs of everyone. Some of the filters are better than others, so you will probably need to do some research online prior to choosing a model for your home. Even so, you will find these units to be expensive to buy and operate, difficult to maintain, and made of materials that are not eco-friendly which means they may not be the best option in the long run.
Some scientists are touting the benefits of using cacti to purify water. If you think back to high school history classes, you may remember that cactus have been used for water purification in desert regions as far back as the 19th century. These experts claim that a cactus like the prickly pear or the moringa can provide a natural method for cleansing the water you use in your household. Once again, this is an idea that would need more research before you made a decision about trying it.

Convert Waste Paper Into Free Fuel With a Paper Log Maker

As utility bills continue to rise, more and more people are looking for an alternative way of heating their homes which offers significant savings to their heating costs. A Paper Log Maker enables you to recycle your waste paper, junk mail, envelopes and even leaves into free fuel, which in turn should save you money on your heating bills whilst also helping to conserve woodland and reduce landfill. Paper logs can burn as well as wood for up to two hours at a controlled rate in a fire grate or wood-burning stove.
DEFRA (Department for Environment, Food and Rural Affairs) has estimated that each person in the United Kingdom sends around 300kg of household waste to landfill each year, of that under 40% is going on to be recycled. Much of the waste ending up on the landfill sites is used newspapers, cereal boxes, junk mail and envelopes that people simply can't be bothered to sort into the correct recycling bin for collection. This could all be converted into free heating using the paper log maker, and it will also contribute thus reducing landfill and helping to lower your usual heating costs. Estimates show that each household could create around five hundred paper logs just from the waste we send to landfill each year.
There are several different types of log maker. The most popular is the wet fill model. The all metal construction has two levers and a removable well. Using the paper log maker is a simple process. Wet the newspapers, junk mail, envelopes etc. by placing them into a large bowl, bucket or drum full of water. Once they start to break down, lift them out and squeeze to get rid of any excess water. Then place the soggy paper into the paper log maker's well. Once full, press the handles to squeeze out any excess moisture and create the brick shape log. Remove the log and place somewhere to dry. Stack the logs in a criss-cross fashion to enable plenty of air to circulate around them. Once they have completely dried they can be used on an established open fire or in a fuel burner.
The 'dry' fill paper log maker is shaped like a bicycle pump. Pull out the plunger, shred the waste paper and push into the tube. Once full replace the plunger and press to form a small tube shaped log. These logs don't burn for as long as the larger, wet making version, but can last up to thirty minutes on an established fire.
It's a good idea to continue to use the newspaper log maker through the summer months when you are not using your fire, as this will ensure you have a good stock of dry paper logs available once the colder weather returns. A garage, shed or other outbuilding makes an ideal storage area.

Making A Yurt Rafter Ring

One of the most basic components, yet one of the most crucial structural elements of any yurt is the rafter ring. This device holds each rafter in place, ensures geometrical and structural integrity of the building, allows for installation of the essential dome vent and must be installed so as to apply uniform weight and pressure to each rafter at the same time that each rafter equally holds it in place. There are a number of pieces that make up this assembly, whether it is designed and constructed in-house or custom ordered.
The ring, in some instances, is built from one piece of wood. However, this is quite a costly venture, relative to the total cost of the yurt. Other wooden rings use a layered approach, sandwiching a layer of OSB between pieces of dimensional lumber, or the reverse. Other rings are constructed from metal, or metal and wood combinations, while a few are built of polymers. Since most yurt-dwellers have a core of self-sufficiency, I recommend constructing the ring completely from dimensional lumber, in layers.
For this piece of your modern Mongolian yurt, you will need fourteen eight-foot lengths of one by six spruce, fir or pine planks. As well, one quart of carpenters glue and one hundred eighty two-inch construction screws complete your parts inventory. For tools, you will need a variable speed drill, ½ inch drill bit, screwdriver bit, jig saw with blades and a small paint brush.
Begin by cutting all of the eight-foot lengths of planking into four-foot lengths. Lay them side by side, using nine pieces on the first layer to form a near-square. Due to the actual width of a six inch plank (5.5 inches) he total width should be 49.5 inches - slightly wider than the length. At this point, this is not important. Next, tie these boards together temporarily, using one of the four-foot lengths screwed across the centre point of the nine boards. Apply a liberal coat of carpenters glue to the surface.
For the next layer, lay the second set of nine boards perpendicular to the first layer, with the leading edge flush with one side of the 49.5 inch width. This will leave 1.5 inches of the first layer exposed. Later, that surplus will be removed. Put one screw at each end of the nine boards of the second layer. Since there is no lateral security using single sets of screws, you now are able to square the assembly, using a standard two foot square. Holding the setup in place, set one screw every six inches, alternating from one side of each board to the other. The screws will protrude beyond the bottom side of the first layer at this time.
Flip the two layers over, applying a layer of carpenters glue to the underside of the first layer. Lay the third layer of boards perpendicular to this first layer, and attach exactly as you did with the second layer. Allow the assembly to dry, then use a saw to remove the 1.5 inches of excess width on the second layer.
Use two strings from alternate corners of the square, so that the two strings cross over precisely in the centre of the box. Secure a nail here, then tie a string that is exactly the length of the distance between the centre and any side to the nail. Be sure that the string or twine is not stretchy. If necessary, use a thin piece of wire. Hold a pencil at the very end of the string, and arc it around the outside of the square, drawing a perfect circle. Now, shorten the string by eight inches, and draw a second circle.
Using your jig saw, cut the exterior run of the first circle. Drill a hole at any point of the inner circle, then use your jigsaw o cut out the centre piece. You have constructed your basic rafter ring. However, for added reinforcement, you may want to screw a band of medium thickness aluminum ring around the circumference of the ring. Alternatively, a ring of 3/16 inch plywood may be glued and screwed to the outer edge.

Why Would You Need A Portable Water Filter?

Years have shown you that you can get by without a portable water filter, so why should you put out the cash for one now? Not that you drink a whole lot of water in the first place, because you'd much rather have a soda or another cup of coffee, but in a pinch you can always buy bottled water. So what's the big deal about people buying straws and drink cups that have filters in them? Is this really a necessity of 21st century life?
To start with, no matter how young you are, you need to start thinking about your health. When you're hanging out with friends, the Cokes and beers probably flow freely. However, beverages other than water aren't providing your body with the hydration it needs to stay healthy. Without enough water in your system, your kidneys can shut down, and waste products remain in your system far longer than they should. Only water will do an adequate job of sustaining your healthy body and mind, which is a good argument for carrying water with you at all times.
Bottled water is proving to be no bargain. People spend a fortune on bottled products that don't contain water that's any better than what they can get from their own taps. In fact, many of the bottling plants actually pump local tap water into their bottles, and municipal water is far from perfect. If you're looking of water that's of a consistently-high quality, you're better off using a portable water filter and creating your own.
It's no secret that our freshwater resources are in short supply and seriously polluted with substances that can cause sickness and death. The big outcry against acid rain back in the latter half of the 20th century arose about the time that people realized that a multitude of chemicals evaporate into the air where they combine with water vapor and fall again as rain which flows into our lakes, rivers, and groundwater. In addition, scientists have determined that quantities of metals work their way from the soil into the water as well. Government standards go part way towards cleaning up the water, but there is no longer money enough to update municipal water treatment facilities.
You can't even trust the water that you find in the mountains or other places where you might hike, cycle, or camp. Gone are the days of the sparkling mountain springs, and you need to prepare yourself for the realities of now. Having a portable water filter that you can take with you on these excursions can help to keep you both safe and healthy.

Liquid Batteries Doubling As Stability Control for Weight and Balance, and Ballast

If you look at a hybrid car, or a fully electric automobile, then you will note that they have quite a few Batteries. Those batteries have liquid inside, and that liquid does move around. Yes, often they have membranes, baffles, or even a webbing which also doubles as a component of the battery to help it charge faster, or hold the charge longer. However, as long as they have liquid inside, we might be able to turn that challenge into an opportunity. Okay so, let's talk about all this for second if we might.
There was a brilliant article on Physorg (dot) com recently titled; "Liquid batteries could level the load," posted on February 14, 2012 by David L. Chandler. Interestingly enough, the title of that article reminded me of an old engineering concept that I had long ago about a UAV or unmanned vehicle which would eat itself as it flew, as the wing spar would be wrapped in fuel and as it used up the fuel the wing would decrease its camber, and not needing that extra weight after climb-out it would increase its speed. Anyway you get the point.
Now then, taking this article title in Physorg (dot) com and dismissing what the article was really about, which was distributing the level of electric output - and then considering my engineering design, think about liquid batteries and how they might assist in the stability of aircraft, vessels, motorcycles, cars, rail, submarines, or other transportation devices when it really matters. What if the batteries were not box shaped, but layered on top of each other?
What if some of these batteries were redesigned either in long tubes, or very flat, going the length of the vehicle, or the length of the fuselage in an airplane? What if the batteries were quite large and went across the width of a large ship or vessel? What if they were used as stability control for submarine? There's actually no reason we can't do it, although it would take a little bit more engineering, and a little bit extra innovation.
Perhaps it's time to send the batteries back to the drawing board, and incorporate all those new battery technologies, which happened to use liquid, and figure out what we can do here? Even if we cannot modify the batteries in the way in which I suggest, perhaps they might be on some sort of a roller system where a very simple computer program working with a gyro can place them in the proper position as needed to serve as the ballast for stability control, or even steering? Please consider all this and think on it.

Solar Panels

In general, solar energy can be described as the energy that is received from the sunlight and converted by a mechanical source for home use. It's cheaper and reliable for operations since the sun is readily available. On the other hand, solar panels are the mechanically built materials whose main purpose is to convert solar energy to electrical energy. They are built from an element called silicon. It is the core duty of the silicon element to covert the solar energy to electricity. The solar power can either be directly or indirectly gotten from the sunlight. When it's cloudy the intensity of the solar power delivered perfectly, the photovoltaic solar materials deliver sun rays into electricity and the solar thermal receiver changes the solar power into heat solvents, such as oil and water. This type of power is used in, iPod chargers, charge batteries water heaters, cell phone chargers and spacecrafts.
How do solar panels work? They practically work on the photovoltaic invention. Its name is derived from the technology used, which is also known as PV, which is made from silicon element. They are basically semiconductors made from sand built into large computer chips. When sun rays falls on the PV materials, the PN junction in it with its metal conductor helps produce electricity. At this juncture, the PN junction is the positive and negative charges that assist to produce electric current. Solar energy is available in different systems, grid connection, inverters and power storage. In a different system, the PV takes up large space up the roof to produce more energy. It can also be built on land space and produce up to 5-9 Megawatts per hour. They can also be useful in street lighting.
How are solar panels made? They are basically made from three-dimensional points; the crystalline silicon production, the crystalline silicon panels and the amorphous silicon panels. This stand of the solar-energy production is what is used in the present. In the crystalline silicon production, for example, when the silicon element is melted and cut it is named the poly crystalline silicon. In its other mode when it is built and cut, it becomes mono-crystalline silicon. In both cases, they are about; a hundred percentage pure silicon. In the second case of the crystalline silicon panels, they are normally broken into pieces and then sliced, finally being polished with doping materials. This changes the state of electric charge inside them to cells. The amorphous silicon panels are made from silicon alloys combined with multilayer cells for energy production. This combination explains how the solar power is made.
What are latest technologies of solar panels? The newest technology of solar energy has emerged in a wide range of things. This starts with the green power alternatives which is common for home use. The other aspect of it is the Power cooling and heating systems in homes. The high-technology appliance and periodic lighting at home is the other good examples of solar-energy development. New personal computers development for smart homes is also left out of the latest ideas of the solar power.

MIL-PRF-680: Strong Enough for the Military and Your Company's Industrial Cleaning Needs

Those familiar with industrial degreasers know that MIL-PRF-680 is most commonly used by the military to maintain equipment, weapons, and vehicles. However, it can benefit any company that requires industrial chemicals to clean "high-value" parts and aging equipment, machinery and fleets that operate on air, land, and water.
The measure of a quality industrial degreaser is that it is both essential and efficient. While its record of accomplishment of cleaning Department of Defense parts and equipment clearly demonstrates MIL-PRF-680 has the highest cleaning capability, it also offers several additional advantages to traditional degreasers.
No Odor
This product does not have the strong odor of many traditional degreasers, which creates not just a more pleasant work environment, but also a potentially more productive one. The strong chemical smell of a traditional degreaser can overtake a workplace, becoming almost impossible to remove once it permeates objects. Prolonged exposure to these traditional products can make employees dizzy or even sick.
No Water
As a water-free industrial degreaser, MIL-PRF-680 can help lengthen the lifespan of critical machine parts. Degreasers that contain water can seep into equipment, causing it to rust from the inside out. Additionally, degreasers that contain water do not stick well to the surface of the part being cleaned; causing a runoff that wastes the degreaser and causes slippery work floors.
No Residue
It evaporates fully, unlike traditional degreasers that leave a residue. Industrial degreasers that leave residues actually attract dirt to machine parts, thereby increasing the number of intervals between one cleaning and the next. A non-residue product like MIL-PRF-680 serves a two-fold purpose of keeping parts clean while saving the company money by using less of the product at a time.
No Hazardous Ingredients
The high toxicity and numerous Hazardous Air Pollutants (HAPs) of traditional degreasers make them dangerous to workers and the environment. Along with workers' health potentially being harmed by those cleaners, companies can find themselves in a tough spot when the Environmental Protection Agency bans the use of a highly toxic degreaser. Using an environmentally friendly degreaser like MIL-PRF-680 will help companies stay ahead of changes made to EPA regulations.
In short, it is not just the military that needs industrial strength products that reduce hazardous waste and minimize worker exposure to toxic substances. All companies desire industrial cleaning products that are safe, and can still achieve demanding performance requirements. This is a safer alternative to the once commonly used cleaner PD-680.
MIL-PRF-680is effective in a variety of work environments, ranging from the mildly dirty to extremely dirty (grease, oils, epoxies, resins, coating, dirt, dust, fingerprints, etc.), where industrial chemicals are needed to clean parts and equipment. Countless businesses are in need of such a solvent that can clean almost anything, no matter the condition.
