Four Renewable Energy Technologies You Should Know About

By Shirlyn Dee

Increasing public demand for oil, coal, and natural gas has brought up the prices of these commodities into ludicrous unimaginable value. In a span of 10 years how much would it cost a liter of gasoline? Or would there be any left in a span of 10 good years?

Renewable energy has developed clean energy resources and had marketed its usage over the past years. It has always been vague to use sustainable energy to collectively name it when there are various Clean energy resources which are far more abundant than that of oil, coal and natural gas is. But what are these green energy technologies that offer solution to everyday energy consumption? Here are 4 of them for you to know and memorize.

First stop is the Solar panels. People have been familiar to the solar panels for their trusty calculators but a solar panel that could cut down energy costs is something else to see. Renewable energy marketing has introduced solar panels as an efficient way to provide heat for water and homes but that is just the beginning. Photovoltaic panels convert light energy to electricity. It can surely light your homes and make your energy worries lighter. What’s more is that the sun as a sustainable energy source is openly accessible to anyone and everyone. Renewable energy resources should be further explored, such as the sun, to make use of its abundance.

Second would be bio fuels. Leaving the house hold concerns aside, bio fuels are more commonly used to power cars. Unlike conventional fuels, bio fuel is produced from fermented crop products which are high in sugar or from plants that contains high amounts of vegetable oil. Bio fuel has several other usages such as for cooking and heating homes. This technology has just been further develop in more later years than the other technology but it has been so far the most frequently used by normal consumers so far. It is cheaper than the other renewable energy resources. The technology works on converted cars as well as specifically designed ones.

Biomass on the other hand is large with large land owners as well as farmers. Owning a farm means having more than enough fertilizers to come around. Whether it is animal droppings or just unused crops and vegetables, production of biomass to fuel stoves and farms would be a breeze.

Windmills are not just for windy days. Coming in at fourth is the ever loved wind mills or as we call it today, wind turbines. Wind mills are not just for grinding corns and drawing water by the stream, kinetic power from the wind can be easily converted into electricity. Wind turbines are used mostly in European country because of the abundance of space and breeze coming from all direction. One 3.3 km wind turbine can answer any man’s prayer for free energy. Costly, yes, but for those who can afford; wind turbines will save you a lifetime’s worth of electricity bill!

2012, Global Warming, and So Called Prophesy

By Lance Winslow

Apparently, we have far too many people worried about prophesy; things such as Nostradamus’s bizarre riddles which can fit nearly any period; past, present, or future, as it reads much like a Machiavellian based future tale, the types of things which history is constantly repeating. Others are fearful of the Mayan Calendar and say that Global Warming maybe the cause?

Global Warming is an interesting topic, of course as you probably know back in the 1970s they were scaring everyone that we were going into an Ice Age, and well, warming sure sounds a lot better to me than freezing to death. The rising of the oceans seems a bit incorrect, but it sure adds to all the confusion and fear! But the calculations are all wrong, and the whole thing is speculative to say the least.

Now then, it is quite possible that 2012 could be a significant year due to the possibility of Solar Maximum getting back into full-swing, perhaps, more human conflicts, more Hurricanes, extreme weather, droughts, etc., but the year itself doesn’t ring a bell when studying prophesy. Actually, the Mayans just ran out of stone, when they were writing their calendar is all. Had it been larger they could have gotten quite a few more centuries carved into that darn rock, well from the archeologists I talk too anyway.

Still, regardless of Global Warming, water will be a huge deal in the future, actually it is right now. We are reaching a horrible crisis with fresh water all over the world actually. There will be lots of infrastructure emergency investment world-wide in the future. There will be need for desalination plants, severe water rationing, as well as issues with agriculture, food supply and unfortunately potential water wars over which nations or people’s own the regions natural flows of water. Please consider all this.

Learn How to Travel While Stopping Global Warming

By: Nathan Brown

The stresses of daily life are growing increasingly pervasive and it seems harder and harder to find time for yourself and your family. Doesn’t a week-long trip to the tropics sound refreshing? I’ll say!

Unfortunately, vacation traveling is a major contributor to global warming because it is very energy-intensive (read: it burns a lot of fossil fuel). The Main Problem With The Hospitality Industry Is It Encourages People To Travel By Burning Fossil Fuels

Most people have, at some level, an innate desire for adventure. By creating an allure of locations that are often far-off, the hospitality industry capitalizes on that feature of your psyche. Indeed, the hotel industry in the US alone posted a profit of $16.7 billion in 2004 according to Smith Travel Research.

For mother earth, the downside of this manipulation is that getting to these enticing locales in the speed and comfort expected by most Americans requires the burning of fossil fuels on a tremendous magnitude. The Main Issue Isn’t the Hospitality Industry, It Is Fossil Fuel-Based Travel

With the recent renewed interest in global warming and heightened concern for environmental degradation and social justice, many people have started to pay attention to the impact of the hospitality industry on the environment and on local peoples. As a result there has emerged a new sector of the hospitality industry known as “eco tourism” or “green travel”. Eco-tourism is defined by the Global Development Research Center as “responsible travel to natural areas which conserves the environment and sustains the livelihood of local people”.

While ecotourism may look like a positive step, what this approach fails to address is what many scientists consider the biggest challenge modern humanity will face: global warming. Beginning around the 1850s, humans began using copious amounts of fossil fuels, adding an abundance of carbon dioxide to the atmosphere, the result of which has been a steady increase in the average temperatures of the earth’s surface.

Eco-tourism fails to address the issue of global warming because it focuses on changing the hospitality industry, without addressing the more significant issue of the fossil fuel based travel which the hospitality industry depends upon. If You Want To Help Prevent Global Warming I Suggest You Stop Focusing On The Hospitality Industry And Turn Your Attention To Vacationing Without Burning Fossil Fuels!

The earth’s atmosphere is a complex entity that influences a great number of other systems on this planet. Since it’s hard to observe changes in the atmosphere with the naked eye, you wouldn’t be likely to connect the act of taking a long vacation with the occurrence of a natural disaster. However, the events are linked through the exorbitant amounts of C02 emitted from the plane.

In fact, numerous consequences are expected as a result of the global warming caused by the burning of fossil fuels, a few of which include: more extreme hurricanes, greater flooding (which may cause desertification), landslides, loss of habitat and species extinction, water scarcity, and the spread of disease. Furthermore, some of the effects of global warming will contribute to further climate change, in what is known as a positive feedback cycle.

When framed in this light, you may begin to change how you feel about burning fossil fuels for amusement. Don’t despair though! It is possible to have a pleasurable vacation while still helping to stop global warming. How you ask? It’s easy – the next time you’re planning a vacation, make it a priority to reduce the total miles you travel.

However, even if you focus on reducing the distance you travel, going on a vacation will most likely involve traveling some distance away from your home. To address this you can travel using methods that contribute less to global warming. For example, you can take a train instead of a plane since train travel uses far less fossil fuel to transport you the same distance.

Porcelain Pottery Making and Methods

By Victor Epand

In making porcelain, ceramic material is treated and heated and clay is included in the form of kaolinite. The temperature is between 200C to 1400C. The porcelain material is blazed at high temperature, so it is very tough, translucent, and high in strength. It is white polished cowry and its name is derived from the old Italian word porcella. Porcelain has the properties of low permeability and flexibility, high strength, solidity, glassiness, permanence, whiteness, fineness, significance, fragility, high resistance to chemical attack and thermal shock.

Tables, kitchen ware, sanitary items, fine art, tiles and decorative things are the items made from porcelain. It has a high resistance to the flow of current and therefore porcelain is a good insulating material. Dentists use porcelain in making false teeth, crowns, caps etc.

One material used in making porcelain ware is clay, but actually clay is used only in small proportions to the whole. The main materials used in preparing porcelain are highly variable, but china clay consisting of the mineral Kaolinite is often the most important ingredient. Other materials added with china clay for producing porcelain clay are steatite, glass, steatite, bone ash, quartz, petuntse, alabaster and ball clay.

According to the degree of plasticity the clays are described as long or short. Long clays are of higher plasticity and are sticky. Short clays are of lower plasticity and thus are not cohesive. Porcelain clays have lower plasticity compared to other clays which are being used in making pottery.

The method used for forming, decorating, finishing, glazing and firing ceramic wares is given below-

Forming: The porcelain pottery is formed by pulling clay upward and downward into the desired shape. It can also be formed on a wheel. The throwing of clay seems to be very easy when it is done by an expert potter. Mishandling of the workpiece can destroy the shape of the item.

Glazing: It has been considered that the initial glazes are unintended, and these are due to the existence in the furnace of lime-rich firewood ash, which proceeds to the exterior as a flux. The iron-containing glazes were designed especially for their prominent sound effects on porcelain.

Decoration: The porcelain wares are decorated with the help of cobalt and copper. In modern wares these are chowder-fired at 1000 Celsius, and then they are sent to glazed-firing at a temperature 1300 Celsius. In Chinese and European method both the process are done in single operation.

Firing: it is the process of heating unfired ceramics at high-temperatures in a furnace to prepare their final shapes. Compared to earthen ware or stone ware porcelain is always fired at a higher temperature to vitrify the clay and make it non porous.
