Solar panels aren't new. The technology has been around for quite a long time. As all of us are well aware, burning fossil fuels to produce energy isn't doing the natural world much good and increasingly brings us into contact with politically unstable states. And so now could be the moment to perform your bit for your country and fit solar panels to generate electricity!

An electric solar panel uses photovoltaic or PV cells to turn the Sun's energy into electricity. The electricity can then run our lights and devices. A PV panel is constructed from crystalline silicon. Photons from the sun strike the silicon and electricity is generated using the photovoltaic effect.

I can really only think of 2 reasons for installing electric solar panels. This first one is economic and the other one is environmental. Some people install them for environmental reasons. But unless you're Prince Charles or James Lovelock, the majority of us will require a sound economic reason to trigger us in making the investment. Eventually, you may find that having solar panels fitted into your home might well increase it's value. The very next owners will certainly be saving money on their electricity bills.

So, we come to some of the benefits you may enjoy if you decide to put in and use electric solar panels. You can lower your electric bills by around 40% even in the UK.

Solar energy is environmentally friendly. It does not discharge any pollutants including carbon dioxide. Sleep better at night, smug in the warm glow that the contribution to the planet has afforded you. Theoretically, you can actually make some money from your panels by selling excess electricity back to the grid. The power companies are legally obliged to purchase this electricity at an inflated rate. Usually around 18p per KW. You are able to store extra energy in batteries and use them during rainy days or when needed.

Solar panels, correctly installed, will last for over 30 years. Of course, you can find a few things to consider. The solar panels are relatively heavy. You will want to make sure that your roof is robust enough to carry their weight. It is best to consult a construction specialist for proper structural assessment of your roof. You will want to ensure that you have a clear line of sight to the sun. i.e. no buildings, trees, or any structure will block the sunlight going to the panels. This is to capture the highest possible amount of sunlight to generate more electricity. Visit your local planning authority to check if you need permission to install electric solar panels.

The price of putting in an electric solar system differs and depends largely on their size. A typical 2.2 KW solar panel system is priced at about £12,000. The cost of electric solar panel systems per KW range from £4,000 to £8,000. The costs per KW will decrease as the system size increases. Generally speaking, you should see a return on your investment in around 10 years. So, maybe now it's the right time to think about installing some electric solar panels.

Fiddling with electricity can be a very dangerous occupation. When I need any electrical work doing myself I call in a qualified person. I can usually get this person from a good company by using the search term electrician london. I use this term particularly because most of my properties that I own are situated in London.

"The promise of the Information Age is the unleashing of unprecedented productive capacity by the power of the mind. . . . The dream of the Enlightenment, that reason and science would solve the problems of humankind, is within reach."

Such is the optimistic conclusion of Manuel Castells in his massive trilogy, The Information Age: Economy, Society and Culture. Within the same conclusion, however, this professor of sociology at the University of California, Berkeley, cites as prerequisites many miraculous changes for society and culture in this global social conscience. And the likelihood that these miracles will be realized seems as remote as the Emerald City in The Wizard of Oz.

Consider several "if only" rainbows that society and culture must chase before we can walk the yellow-brick road to Castells's utopia: "If people are informed, [are] active, and communicate throughout the world; if business assumes its social responsibility; if the media become the messengers, rather than the message; if political actors react against cynicism, and restore belief in democracy; . . . if we assert intergenerational solidarity by living in harmony with nature; if we depart for the exploration of our inner self, having made peace among ourselves."

What Castells doesn't seem to realize is that human nature is the wizard behind this curtain, and unfortunately he doesn't see that for what it really is. In his conclusion he states that "there is no eternal evil in human nature." Yet he warns in his third volume that the Information Age has the potential to greatly expand the gap between rich and poor nations, that the weakest in society (especially children) stand to be exploited by the new global economy as never before, and that a rising global criminal economy will wield unprecedented power.

In the same volume he readily admits that "we are all inhabited, at the same time, by humanity's angels and devils, [and] whenever and wherever our dark side takes over it triggers the release of unprecedented, destructive power." Castells is to be applauded for recognizing that human nature is at the crux of the success or failure of the Information Age, but his optimism is not supported by his analysis of these monumental changes. In fact, he identifies the potential for more negative than positive scenarios as the world speeds blindly into what many believe will be the greatest social upheaval in the history of humanity.

To be fair to Castells, he does not intend to suggest a coming utopia. His intent with this work was not to engage in futurology, but to present the situation as it presently exists and to identify the social and economic factors that would be most affected by the technological revolution. He acknowledges his optimism but defends it when he writes, "I believe in rationality . . . without worshipping its goddess. I believe in the chances of meaningful social action . . . without necessarily drifting towards the deadly rapids of absolute utopias." The question that remains is whether the new technologies will bring society and culture a better world or whether they will be used for destruction, as were all too many technological advances in the 20th century.

NETWORK VS IDENTITY

Castells will certainly have a major impact on the debate about what traditional institutions should or should not do to influence the progress of the Information Revolution. The author of more than 20 books, many dealing with the impact of information technology on society, he is recognized by business leaders and academicians alike as the premier expert on the social ramifications of the Information Age.

Castells has long been a citizen of the subject on which he is an expert--the new global economy and culture. He himself is a globalized social theorist. Born in Spain in 1942, he taught at the University of Paris for 12 years before moving to California. He has taught and conducted research all over the world and has been an advisor to heads of state from Europe to Latin America to Asia. He has been a member of the European Commission's High Level Expert Group on the Information Society and is a member of the European Academy.

In the last year, Castells has also become a star speaker at major conferences on the Information Age. He was one of a very few academics to address the World Economic Forum earlier this year, with an audience that included George Soros, Bill Gates and Kofi Annan.

In his trilogy, Castells describes a tension that new information technologies have created within the society and culture. He identifies it as a battle between "network" and "identity."

Volume One is titled The Rise of the Network Society. In it he introduces a new term, informationalism--a new economic model evolved from capitalism. In the new economy, information is the most important currency, and new models of production are forming as a result. Castells illustrates how the global economy is now reliant on the continuous and instantaneous flow of information, and how that flow has changed consumption and production. Enormous power has been invested in those who control the information pipelines, and very often that power goes politically and legally unchecked.

Volume Two, titled The Power of Identity, shows the major counterforce to networks and globalization: old and new groups expressing their collective identity. Here Castells identifies social (and to a lesser degree economic) communities that are emerging, and he comments on their shifting and transitory nature and how they are undermining the old structures, including ethnic cultures, the family and the nation-state.

In his final volume, End of Millennium, Castells brings together the findings from the first two and sums up where he believes society and culture is as it enters a new millennium. And while he focuses on Africa, the rise of inequality, the growing criminal economy, urban poverty, and the plight of children, he still has faith that "there is nothing that cannot be changed by conscious, purposive social action" that is informed and legitimate. Yet he resists making firm predictions and concentrates on, as he puts it, "what we know the Information Age brings to us."

EMPIRICAL WEAKNESS

The three volumes work together to establish the fact that a new global economy and culture are emerging, driven by the engine of capitalism. This new state of affairs will in turn come under threat from the pressure of other social movements, ethnic groups and virtual cultures that are arising in response to the rapid shrinking of the globe. All of these forces will utilize the speed and pervasiveness of the network to stake out, defend and promote their identity. Information capitalists, nation-states and traditional institutions will have to take each potential threat seriously, no matter how insignificant it may seem initially.

Castells cites the success of the Mexican Zapatistas rebellion as evidence. This relatively small and isolated group, devoted to preserving the culture of those native people of Mexico who were threatened by global interests such as NAFTA, was able to hold the Mexican government at bay by appealing to the greater global community for support via the Internet.

Yet it seems the new technologies put all entities at risk. The very same special-interest groups and individuals that are empowered by unlimited information will also have their identity threatened by competing social movements. Thus no one will have a secure sense of identity.

It is no surprise that Castells, a former Marxist, concentrates on the plight of workers through all of this change. He believes a major consequence will be great uncertainty in employment resulting from a dramatic change in how we work: labor pools will be defined increasingly by temporary ventures that Castells terms "projects"; corporate firms and businesses will constantly shift their focus; and many firms will become sources of capital as opposed to producers of goods and services in the traditional sense. These factors may work together to produce a situation not unlike that of the 19th century, when vast groups of people were uprooted to fulfill the labor needs created by the Industrial Revolution.

These are just a few of the general trends that Castells attempts to identify. While the three volumes are long on data and short on firm conclusions about the future, the specifics he addresses in illustrating his points make for interesting reading and prompt the reader to consider various what-if scenarios. But one comes away from the trilogy recognizing that the subject is so big that even the best minds writing in such magna opera as Castells's are incapable of giving us the full sense of the revolution we are witnessing.

The advance of the Information Age is in many ways like the development of a new empire, though this empire is not limited, as others before it have been, to time and space.

Several questions remain, however. At what stage are we currently in the life of this new global empire? Will the global economy and culture prevail, or will society fragment? Can the dark side of human nature be overcome before the full power of the Information Age is unleashed? This is the drama for which Castells wisely refuses to provide an ending.

So often in the past, the real enemy of empires was not the foe without but the dark side of human nature within. More often than not, empires collapsed because of internal social forces at work--the moral decline and eventual collapse of the Roman Empire being perhaps the most notable example.

The astonishing powers being unleashed by the explosion of information technologies will demand strong ethics and morality from the citizens of this new global empire if it is to enjoy a happier fate.

Has NASA, the monolithic space agency, failed in it's quest to put man out into the cosmos. Will profit coupled with mans need to explore be the driving engine which sends man into the cosmos. Think about what has moved technology forward within the American society over the past 100 years or so. Was Orville and Wilbur Wright employed by the government. Of course not. Most of their research and development for the invention of the airplane took place within a small bike shop in western Dayton, Ohio, the birth place of aviation. Thomas Edison, who is accredited with 1,093 patents earning him the nickname "The Wizard of Menlo Park" used his own money to build the Menlo Park research labs in New Jersey. In 1889 Thomas Edison established the Edison General Electric Company. Thomas Edison is considered the most prolific inventor of our time and his inventions were created within the realm of private enterprise. Did the seed for the invention of the personal computer germinate within a government lab. The invention of the personal computer came from an assortment of various inventions and from the tinkering of Steve Jobs and Steve Wozniak in Job's garage in an area now called Silicon Valley. Their tinkering led to the development of Apple Computers. The story of Bill Gates and the development of the Microsoft family of operating systems took place within private enterprise. The Windows family of operating systems is the most widely used on earth and has been a major player in bringing information technology to the developed world.

Examples of major technological advancement within the realm of private enterprise are numerous. Most major technological advancements within society have occurred outside the purview of government intervention. Governments were intended to govern the people. The governments role is to preserve the environment of freedom and democracy so that intellectual curiosity can flourish within this environment. The governments role is also to provide funding, and should not be in the nuts and bolts operation of putting man into space. The ingenuity of man within the realm of private enterprise has resulted in most of the technological advancements we enjoy today.

The cosmos will be explored by man operating from the base of private enterprise and the technology needed to explore the cosmos will be developed within that enterprise. Why is this so. NASA is an agency driven by fear of tragedy. More mishaps will decrease the probability of sufficient government funding. This cycle of fear, mishaps, and the hope for continual funding is one that seems to have no end. But mishaps are part of the business of putting explorers into space. What can better withstand the expected mishaps. A government agency or private enterprise. If a private enterprise fails, it's competitor can step in to fill the gap and the engine of private enterprise can continue to push man into space. NASA is not a private enterprise competing within the world market place.

NASA is not what it used to be during the Apollo days. Given it's current mind set and culture, it will be difficult within this framework to send man out into the cosmos as true explorers. They have given the nuts and bolts of putting man into space to private contractors. But these NASA contractors have the same NASA mind set because they are under the dominion of NASA. There is a fear of mishaps within contractors without true competition within the market place. NASA awards contracts to the lowest bidder. Does the lowest bidder provide the highest level of safety. Once a company is awarded a contract, they remain a NASA contractor for many years and simply become an extension of NASA. Therefore NASA becomes a autocratic agency with it's arms extending outward to many companies. NASA's manned space flight program can do no more then low earth orbit. Year after year of low earth orbit does not excite the American people. Astronauts today are no longer household names. An American president here and there will give a speech saying we are going to Mars. Even President Bush's January 14, 2004 speech seems to have already been forgotten by the American public.

When we went to the moon this was the start of an exploration. A goal was set on May 25, 1961 by President John F. Kennedy, during a speech before a Joint Session of Congress, to reach the moon before the end of the decade. NASA kicked into high gear and achieved one of the greatest accomplishments in the history of mankind. We took the first step into space and then just stopped. Since then all of the manned space missions have never gone beyond low earth orbit, and the American public becomes bored easily. To gain the American interest and support of the Apollo days, we must send true explorers out into space. NASA wants to take such small, time consuming incremental steps that by the time comes when the really exciting work begins, the American support and interest may be eroded to the point where NASA may no longer have the financial means by which to accomplish such an endeavor. Hence, the need for private enterprise to accomplish such an endeavor. If we are going to go into the cosmos, then lets do it and stop the futile activity.

A private enterprise is not a bureaucracy. If safety issues arise from qualified personnel within a bureaucracy, these issues may not resonate to the proper people within the organization. A case in point, the knowledge of a strong potential for a O-ring failure at low temperatures between the segments for the solid rocket boosters of the space shuttle, existed within the bureaucracy of NASA before the Space Shuttle Challenger explosion. More specifically, this critical information in terms of probability of O-ring compromise was expressed by engineers at Morton Thiokol, the contractor for the development and production of the solid rocket boosters. This information never percolated upward from Morton Thiokol to the proper people within the NASA organization.

In private enterprise, which is non-bureaucratic by nature, a relatively small group of people are working toward a common goal. In this situation, safety issues which arise will be known by all members of the organization. Safety issues will not get lost in a bureaucracy. NASA depends on it's contractors to deliver a high level of safety. A private enterprise depends on itself to provide a high level of safety. The structure of a private enterprise is more suited to the endeavor of sending out explorers into space. The government should award grants to the most promising companies with the understanding that the sending out of explorers into space does indeed benefit mankind.

Americans are at their best when they compete. Competition is an integral component of American society. What was the driving force that put us on the moon. It was the competition with the Russians. At the present moment in time, this type of competition does not exist. Although, it appears as if China may be a future competitor. Americans need to compete to accomplish something. It is competition which drives the advancement of technology. Why not let companies compete for government funding and let the research and development occur within these companies, and most importantly let them compete. These companies can have the same characteristics of any company that wants to produce a viable product. They will not be under contract from NASA and will operate as a separate private enterprise entity. A company can make money from space tourism and the same company can be involved in sending explorers out into space. Government grants can be awarded based on how strong the potential exists for space exploration. A company can be involved in space tourism, exploration, or can provide a research and development platform. This is the future of man's endeavor into space.

Man will be exploring the cosmos with private enterprise being the driving engine. If one enterprise fails, one of the competing enterprises will win out. Sure there will be some disasters and risks will be taken because that is the nature of the business. But when unfortunate disasters or mishaps do occur, the private enterprise engine will not grind to a complete halt. Burt Rutan and his Scaled Composites team have taken the first steps toward this archetypical dream of exploring the cosmos, and they did it with a fraction of the budget that NASA uses and with a team of 130 or so people to boot. They won the Ansari X-Prize by sending a man into space and returning him safely to earth and then they repeated this within two weeks. An absolutely unbelievable accomplishment given the facilities and resources which were available to them. This could only occur within a society where freedom and democracy are regarded as a right to all individuals. The United States is such a society.

Burt Rutan has said that he has never worked a day in his life. He only plays. His passion for his work is what produces results. Burt Rutan and his team represent the core of what makes the United States the greatest country in the world. May be terrorist can get it through their thick heads that freedom does work. Most importantly, Scaled Composites has shown the world what private enterprise can accomplish. Even if Scaled Composite's endeavors never go beyond earth orbit, they have taken the first step within the proper mind set and culture, and this is what will put man into the cosmos. This mind set and culture of pure unadulterated intellectual curiosity is what really will put man into the cosmos. Not NASA's mind set of fear.

NASA has played it's important role by lighting the torch in sending man to the moon. We are now at a point in the history of mankind where that torch should be passed to private enterprise. The developer of the Ansari X-Prize I'm sure shares my thoughts. God has placed the planets and all the stars within the universe there for a reason. It is God's intention for us to move outward into the final frontier. We do this to fulfill the natural curiosity that God has given to us and in the process we better the lot of mankind. Lets go...

Last December ('05), physicists held the 23rd Solvay Conference in Brussels, Belgium. Amongst the many topics covered in the conference was the subject matter of string theory. This theory combines the apparently irreconcilable domains of quantum physics and relativity. David Gross a Nobel Laureate made some startling statements about the state of physics including: "We don't know what we are talking about" whilst referring to string theory as well as "The state of physics today is like it was when we were mystified by radioactivity."

The Nobel Laureate is a heavyweight in this field having earned a prize for work on the strong nuclear force and he indicated that what is happening today is very similar to what happened at the 1911 Solvay meeting. Back then, radioactivity had recently been discovered and mass energy conservation was under assault because of its discovery. Quantum theory would be needed to solve these problems. Gross further commented that in 1911 "They were missing something absolutely fundamental," as well as "we are missing perhaps something as profound as they were back then."

Coming from a scientist with establishment credentials this is a damning statement about the state of current theoretical models and most notably string theory. This theoretical model is a means by which physicists replace the more commonly known particles of particle physics with one dimensional objects which are known as strings. These bizarre objects were first detected in 1968 through the insight and work of Gabriele Veneziano who was trying to comprehend the strong nuclear force.

Whilst meditating on the strong nuclear force Veneziano detected a similarity between the Euler Beta Function, named for the famed mathematician Leonhard Euler, and the strong force. Applying the aforementioned Beta Function to the strong force he was able to validate a direct correlation between the two. Interestingly enough, no one knew why Euler's Beta worked so well in mapping the strong nuclear force data. A proposed solution to this dilemma would follow a few years later.

Almost two years later (1970), the scientists Nambu, Nielsen and Susskind provided a mathematical description which described the physical phenomena of why Euler's Beta served as a graphical outline for the strong nuclear force. By modeling the strong nuclear forces as one dimensional strings they were able to show why it all seemed to work so well. However, several troubling inconsistencies were immediately seen on the horizon. The new theory had attached to it many implications that were in direct violation of empirical analyses. In other words, routine experimentation did not back up the new theory.

Needless to say, physicists romantic fascination with string theory ended almost as fast as it had begun only to be resuscitated a few years later by another 'discovery.' The worker of the miraculous salvation of the sweet dreams of modern physicists was known as the graviton. This elementary particle allegedly communicates gravitational forces throughout the universe.

The graviton is of course a 'hypothetical' particle that appears in what are known as quantum gravity systems. Unfortunately, the graviton has never ever been detected; it is as previously indicated a 'mythical' particle that fills the mind of the theorist with dreams of golden Nobel Prizes and perhaps his or her name on the periodic table of elements.

But back to the historical record. In 1974, the scientists Schwarz, Scherk and Yoneya reexamined strings so that the textures or patterns of strings and their associated vibrational properties were connected to the aforementioned 'graviton.' As a result of these investigations was born what is now called 'bosonic string theory' which is the 'in vogue' version of this theory. Having both open and closed strings as well as many new important problems which gave rise to unforeseen instabilities.

These problematical instabilities leading to many new difficulties which render the previous thinking as confused as we were when we started this discussion. Of course this all started from undetectable gravitons which arise from other theories equally untenable and inexplicable and so on. Thus was born string theory which was hoped would provide a complete picture of the basic fundamental principles of the universe.

Scientists had believed that once the shortcomings of particle physics had been left behind by the adoption of the exotic string theory, that a grand unified theory of everything would be an easily ascertainable goal. However, what they could not anticipate is that the theory that they hoped would produce a theory of everything would leave them more confused and frustrated than they were before they departed from particle physics.

The end result of string theory is that we know less and less and are becoming more and more confused. Of course, the argument could be made that further investigations will yield more relevant data whereby we will tweak the model to an eventual perfecting of our understanding of it. Or perhaps 'We don't know what we are talking about.'

Three hundred miles off the Argentina coast in the South Atlantic lay the Falkland Islands, also known to the Argentines as Islas Malvinas. It consists of two main islands, East and West Falklands which lie 300 miles east of the Argentina coast. There are about 200 smaller islands that form a total land area of approximately 4,700 square miles. The only town and capital is Port Stanley.

The English navigator John Davis may have been the first person to sight the Falklands. However, the Argentine version states that "Spanish seamen" were the first without giving further details. Some also say that Ferdinand Magellan was the first to see the islands on his voyage around the world. Another claim is based on one of Magellan's ships deserting the expedition and going back to Spain. While it is true that there was such a ship, there are no original documents to prove the actual sighting of the islands.

The government of the Falkland Islands administers the British dependent territories of South Georgia, the South Sandwich Islands, and the Shag and Clerke rocks, lying from 700 to 2,000 miles (1,100 to 3,200 km) to the east and southeast of the Falklands.

Argentina has claimed the islands since the early 19th century. Britain had occupied and administered the islands since 1833 and had consistently rejected Argentina's claims. Just like any other conflicts in our world history, claiming and ruling a certain territory initiated war between the Argentines and the British forces. Ownership of the islands has always been a hotly contested issue between the two governments. On April 2nd of 1982, the war began, with thousands of Argentine troops landing on the Falklands.

The British captured about 10,000 Argentine prisoners, all of whom were afterward released. Argentina's defeat severely discredited the military government and led to the restoration of civilian rule in that country in 1983.

After more than 20 years, a shocking revelation unfolds. Research claims that a high number of veterans have taken their own lives since the South Atlantic conflict ended, both from the Argentine and the British troops. The suicide figure was almost half of the number of soldiers who died during the conflict.

There were also allegations that the people in command of the military forces of both countries tried to ignore the issue of Post Traumatic Stress Disorder (PTSD) which leaves many sufferers emotionally scarred and unable to work. Some veterans have claimed that their condition was not diagnosed or treated while they were still serving. They added that they were never warned about the effects on their enlistment or discharge from the forces. They were also not given any presentations or debriefings to prepare them for possible effects.

PTSD is among only a few mental disorders that are triggered by a disturbing outside event, like war. The traumatic event causes a cascade of psychological and biological changes. Wars throughout the ages often triggered what some people called "shell shock," in which returning soldiers were unable to adapt to life after war. Although each successive war brings about renewed attention to this syndrome, it wasn't until the Vietnam War that PTSD was first identified and given this name.

There seems to be a general pattern for war veterans suffering PTSD. They experience recurring nightmares and flashbacks followed by recourse to heavy drinking or drugs then crime. A lot of war veterans ended up in prison often for violence and some of them killed themselves in their cells. While many veterans have been suffering from PTSD, others have simply been unable to cope with the reality of life outside the forces. Many have become caught up in alcoholism, drug abuse, homelessness, depression, and relationship break-up. PTSD has indeed turned these war veterans towards the path of self-destruction.

Today, mental health providers such as psychiatrists, psychologists, and other health care professionals can attempt to understand people’s responses to these traumatic events and help them recover from the impact of the trauma.

The Falklands Conflict was one of the few major naval campaigns to have occurred since the end of the Second World War. As such, the conflict illustrated the vulnerability of surface ships to anti-ship missiles and reaffirmed the effectiveness of aircraft in naval warfare. However, the Falklands War also illustrated the vulnerability of people, especially of war veterans. Even if the war has ended, it has left an imprint that will forever be within their lives.

The Falklands war cost England 255 men, six ships, and more than 1.6 billion pounds. The war lasted 74 days, with 649 Argentine soldiers, sailors, and airmen, and three civilian Falklanders killed. The Falklands campaign was considered a great victory for the United Kingdom. The British may have overpowered the Argentines, but both of them suffered the consequences of the atrocity of war and continuously agonizing from it.
