Solar power has been used by many cultures and creatures throughout history, only in recent years have we begun utilizing it as an alternative energy source. Solar power is harnessed through “photovoltaics, solarthermal energy, and artificial photosynthesis”.{1} Using these technologies , we develop different applications such as” solar-panels” {2a} and/or” heaters, power stations”{2b}, and” thermal radiation collectors.”{2c}

Harnessing solar power requires a photovoltaic system, consisting of the solar array(the panels, the visible photovoltaic system) and the balance of system ( solar inverter, mounting, cabling, and accessories for setup) Sizes and different system capacaties range from small rooftop-mounted or systems integrated into buildings(ranging froms tens of kilowatts) to larger more industrial scales with capacaties of hundreds of megawatts. “A rooftop system recoups the invested energy for its manufacturing and installation within 0.7 to 2 years and produces about 95 percent of net clean renewable energy over a 30-year service lifetime”{3} Given the decreasing cost for photovoltaic systems, in 20 years time, they could be applied forn use from your home to work and in between!
Solar thermal energy is harnessed through temperature-absoorbing collectors, classified by US EIA by low, medium and high temperature ratings. Low-temp. collectors are “usually for swimming pools.” {4a}Medium temperature collection plates are “usually flat plates but are used for heating water or air for residential and commercial use.”{4b}and High-temperature collectors “concentrate sunlight using mirrors or lenses and are generally used for fulfilling heat requirements up to 300 deg C / 20 bar pressure in industries, and for electric power production.”{4c} “The collected energy can be used for industrial processes,…...

Technology and the Future

...Technology and our future Com 156 Instructor - When we think of robot, we usually think of the classic robot of R2D2 from Star Wars. Have you ever thought of a fleet of robots taking our jobs from us? The truth is that we may lose jobs to our electro-counterparts. Technology is advancing at a rapid pace; our jobs and future may be endangered by robots taking over. Some of the robotic advancements developed may sound “out of this world”, but will be reality soon. By 2013 there will be 1.2 million industrial robots working worldwide. That breaks down to be 1.2 million robots to 5,000 humans (Aquino, 2012). The future for robots will result in more advanced designs and possess more complex decision-making abilities. The main pro for a robot in the workplace is that they will not get bored or tired as a human would. Robots are currently analyzing documents, filling prescriptions, and handling other tasks once exclusively done by humans (Aquino, 2012). The result of robots assisting humans in the workplace has resulted in safer work conditions. Robots are used more in the workplace to assist humans as opposed to overtaking their jobs. Firefighting can be very dangerous work, deploying robots for tasks such as search and rescue and extinguishing fires will reduce the injury and death rate. The United States Army has developed a robot called Thermite, a firefighting robot that has proven to reduce the risk of injury and death to humans by the ability to operate remotely......

Harnessing Technology for the Future

...needs for a year. To harvest this bounty, we need technology that efficiently converts the sun’s energy into forms we can use. Developing this technology is the purpose of the U.S. Department of Energy (DOE) Solar Energy Technologies Program. Powerful Goals, Powerful Technologies The Solar Energy Technologies Program is part of the DOE Office of Energy Efficiency and Renewable Energy. The Program’s mission is to improve U.S. security, environmental quality, and economic prosperity through public-private partnerships that bring reliable and affordable solar energy technologies to the marketplace. It supports research and development on a wide range of photovoltaic (PV) and solar thermal technologies that convert sunlight into useful energy. Photovoltaic Technologies The majority of the Program’s budget is allocated to PV research and development (R&D). All PV devices convert sunlight directly into electricity. However, there is a variety of materials and processes for creating PV devices, each with its own benefits and drawbacks. The major trade-off is between cost and sunlight-to-electricity conversion efficiency—higher efficiency typically translates into higher cost. Program participants consistently achieve world-record efficiencies for different types of PV, but each effort has the same ultimate goal: optimizing cost and efficiency to produce the least expensive end-use electricity. Solar Thermal Technologies The sun’s energy can be put to work in......

The Future of Technology

...The Future of Technology Felbert M. Meriweather ITT Technical Institute] The Future of Technology When thinking of the future a person may wonder where they may be, who they will be with and what it is they will be doing occupationally but in the back of our mind we wonder what the world’s technology will be like. Technology is not just electronically but is also things that are made in the matter of improvement like tires that don’t go flat. It is something that has changed the world significantly, giving us the opportunity to do a lot of everyday tasks better than we ever have before. Once upon a time when someone would talk about technology they would only think of basic computers, but today’s technology is considered to be more than just that. Technology has made a huge impact on the cars that we drive, the electronics that we use and it even in our hospitals. Those are just a few of the many things that technology has affected but the question now is how much more advanced can we get in technology and how will it benefit us.. In the car industry, companies have gone as far as improving the tires we use with Air Maintenance Technology (AMT). One of the major things that we as drivers worry about is our tires and their ability to hold air. Goodyear explained its recent improvements in Goodyear’s air (2011), “AMT will enable tires to remain inflated at the optimum pressure without the need for any external pumps or electronics. All components of the AMT......

...Future Technology BIS/220 March 6, 2014 Posey Future Technology The purpose of this paper is to describe the effectiveness and benefits of Google Glass (Glass), and how it may impact the use and need for PC’s, tablets, and smartphones in the near future. Glass is a mini computer placed on the side of an eyeglass frame designed to be worn as glasses and fits customer's lifestyles offering different colors, frame shapes, shades, and earbuds. Glass's frames fit with or without prescription glasses. Glass can also be bought with up to 16 GBs of internal storage with the ability of Google cloud synchronizing. Glass looks like a pair of glasses, but can perform similar tasks as a smartphone, tablet, and PC, hands free and ten times faster, so using Glass increases daily production for businesses and personal use (Glass, 2014). Responding to clients, family members, or friends is easier and quicker with Glass, because its applications are in the form of “cards” and tasks are performed through voice commands. This eliminates the need to search for emails and messages like one would search for on a smartphone, tablet, or PC, and respond with one voice command while doing other activities. Glass’s ability to sync with Google calendar and Apple's iCal also make it convenient to view and schedule appointments and reminders throughout the day (Glass, 2014). Glass, 2014, in addition, through voice command, Glass provides navigation and traffic times for any destination, with......

Our Future with Science and Technology

...Our Future with Science and Technology In Aldous Huxley's Brave New World, Huxley describes a chilling vision of a totalitarian society ruled by both manipulation and conditioning of its' citizens. It ways eighty one years ago that Huxley made this fictional world into a piece of literature that still resonates with his readers today. Social engineering and technology of modern society were either at its' infancy or not even created yet when Huxley wrote his book. The maturity of these ideologies and technologies that makes Brave New World touch close to home. Is it possible to bring a world of chaos to order or is it just a proclivity of the human condition? In Utopia by Sir Thomas More, the city Amaurot is the city of Hythloday's research of Utopian society. His mention of the lack of privacy among its' citizens can be very relevant to today. While we can still lock our doors and windows, close our curtains and blinds, the amount of privacy one has has been increasingly diminishing. With the advent of federal approbation of various ways of the government to invade on a person's right to privacy is a slow progression to the possibility of losing our privacy completely. Others argue that discretion of these actions should not be a worry of the common citizen. They argue that if you have done nothing wrong, you have nothing to hide. It is a way of justification of a deplorable act on our everyday privacy. And the debate will only continue to escalate as the rapid......

...[Type the company name] 2010 Information technology Business with information technology in 2020 Information Technology in the Business World Communication technology is one of the most important aspects of information technology for the people around the world. It has changed human life by making it easier for us to communicate with each other, which makes the world seem like a small village. People now communicate with each other in different ways in comparison to the past. As a result, businesses have also changed and developed using communication technology. Companies using this technology experience both benefits and disadvantages. The discussion will be limited to this area. One of the advantages is that the Internet can help companies to communicate effectively with clients. In addition, companies can use communication technology to build good relationships with their customers. Now, most companies use a website to market their products and services and provide information about their business. Moreover, most companies use virtual communication to provide or exchange information. Conversely, communication technologies have many disadvantages. The first common disadvantage experienced in companies is that employees sometimes use company computers for dubious purposes. In addition, using the Internet in the workplace for an extended period could affect the health of employees. Further, mobile phones are not secure because of digital criminals.......

Future Technology

...Almost everyone believes that technology has made life easier and more comfortable and that it has enabled us to perform tasks that we could not do otherwise. A list of the benefits of technology would be very long indeed. However, as with almost everything we human beings have created, technology has a downside. There is, we might say, a dark side to technology. For openers, technology does not necessarily make life simpler; rather, it tends to make life more complicated. Nowadays, for example, nearly every discussion of the "wonderful power of technology to enrich our lives" mentions the cell phone. Certainly, the instant communication brought about by the telephone has been a boon. It was originally a rather simple device that anyone could learn to use in a matter of minutes, and we soon began using phones to make and receive phone calls, usually about matters of some consequence. Recently, however, we have enabled these devices to perform a ridiculous number of irrelevant functions. One needs a thirty-page booklet to learn how to use them. Anyone who enters a phone store today seeking a phone that simply sends and receives phone calls is likely to be looked upon as a refugee from the Dark Ages – or from another planet. Furthermore, we have millions of people walking about or driving their cars while talking on cell phones, usually discussing matters of no importance whatsover. If an alien civilization were to tap into our phone lines, its inhabitants would......

Technology Increases a Jobless Future

...Technology Increases a Jobless Future Current Trend #2 MISM 3301-01 Antoinette Y. Guerin 14 October 2014 Technology revolution is fast replacing human’s beings with machines in just about every sector and industry in the global economy. It has been calculated that millions of workers have been eliminated permanently from the economic process, with whole work categories and several job assignments have either disappeared, restructured or revamped. Based on statistics Global unemployment has reached an all-time high, since the great depression. The number of unemployed and underemployed human beings exceeds 500 million. Developing nations are facing increasing technological unemployment as transnational companies build your state of the art high tech production facilities, thus releasing millions of cheap labor who can no longer compete with the speed, cost efficiency, quality control achieved by automated machinery (Riftkin, 2012). Thus workers being replaced in this instance not displaced. It has been said that as we progress in this world that computers, smart phones and driverless cars will take over and eventually, we will see a large reduction in the human involvement in the workforce, all the while destroying the employment figures. While the invention and upgrades of the high demand of technology has made a huge impact on the way many businesses operate, and has had a large impact on the downsizing of some company’s mainly manufacturing business.

Future Technology

...Through the time technology has been innovating the way of mobile communications Touchscreens made phones more intuitive than ever, and the next generation of screens promises to revolutionize our habits yet again. Several companies are working on the first phones with flexible screens, expected to hit the shops by late 2012. The innovation inside these bendy screens is OLEDs (Organic Light Emitting Diodes) - thin films of organic molecules that produce light when you run an electric current through them. Often less than a millimeter thick and offering a bright, crisp image with low power consumption, it’s not just flexibility that makes OLEDs a popular choice.  Mobile phone business is one of the most rapid growing industries. Not so long ago, the popular check phone was Nokia 3310 with mere basic functions: call, text messaging and the only bearable game, snake. However, significant improvement has been made since then. We now have so many variety of phones that surpasses the basic function, smart phones for example allows you to connect to social media conveniently, GPS, video conferencing etc Flexible bracelet The Philips Fluid Smartphone designed by Brazilian designer Dinard da Mata looks like one of those "Slap Wrap" slap bracelets kids used to wear in the 90s. Flexibility is one thing that makes it differ from conventional smart phones. Made of OLED, it can keep all the features of a smart phone available while adding the extra advantage of turning into a......

...Employee Information Technology Satisfaction Employee satisfaction pertaining to Information Technology (IT) services is dependant on the degree to which employees feel the IT system is user friendly, while also being able to effectively complete the task at hand (Sun,2012). Additionally, IT employee satisfaction can be defined as the emotions or reaction experienced that determine the value an individual designated to a particular IT service (Sun,2012). In order to assess the level of satisfaction employees are having with IT services, it all begins with communication and collecting the various data required to make the best decisions. Most in healthcare management positions must dedicate their attention to delivering services (Sun,2012). However, management must also have a grasp on what the user or employee opinions are associated with the IT services they use daily. One effective means to beginning the process is meeting in groups. These gatherings bring together employees and leadership to formulate the best way to gather satisfaction feedback. Once the feedback data is collected, the results can shed light on what user needs are being met and which areas may need altered for increasing satisfaction. Surveys perhaps stand as the most common methods to polling IT satisfaction ratings among employees (toolpack.com). Surveys come in numerous forms such as professional standardized or customized and the in house or home grown variety. Organizations may......

(Brightub articles 2011) .explains the well knows macro virus was a stark reminder of its disastrous power. In today’s world of technology computer viruses attack the software of a computer- the operating system usually attacks the software. (Microsoft /TechNet 2011), states the macro virus is known as a written virus in the internal macro language of applications. In some cases macro virus can cause no damage to the data, however; in other cases, macros viruses have been written that can cause damage to your work. This paper explains. What macro viruses are? How they spread. What affect they have? How to avoid a macro virus How to protect your computer What are Macro viruses…..? A macro virus is a computer infraction written in macro language, which is commonly built into word processing applications. (Goggle 2011, pg., 1) In general, Marcos viruses are a series of commands and executions that help automate specific tasks.

Technology of the Future

...WiFi connection or you can always plug in the USB port as well. The most boasted feature of the Kindle, minus the Fire, is the reader display made by using electronic ink technology. This eliminates the problem of glare that you have with a LCD display, especially outdoors with the sunlight. Electronic ink really makes it feel like you’re reading from the page of a tangible book. I was resistant to the increased popularity of the e-reader at first. Being that I am a book lover, the thought of not being able to physically flip the page of and exciting book, or enjoy the smell of an old book was something I did not want to give up. I agreed the idea was genius, but I was not quite ready to jump up on that wagon. One day, and unfortunate spill of juice by my niece on an old time favorite, and the push from my “techy” husband, I made the crossover, and yes I love it. My Kindle lives up to everything the makers Advertise. The capabilities of computers and servers today make all of this possible, and quickly at that. The processing power that is needed to handle the storage of so much data, and process the requests of millions of customers worldwide is insane, and I would imagine that processors of IBM quality (high performance) (Norton, 2006), is what contributes to the mainframes that houses it all. The future looks very bright for the Kindle and other e-readers. They complement our society’s new “green” outlook by saving paper and trees. Some schools have begun to implement......

Future of Health Care Technology

...on June 25, 1963 in the assembly hall at Paulskirche in Frankfurt, Germany said: "For time and the world do not stand still. Change is the law of life. And those who look only to the past or present are certain to miss the future." Health care technology has come a long way from the past, the present, and is definitely moving on into the future. It seems that only yesterday many of our parents were watching the "Six million dollar man" and "Bionic Woman" on television and "Robocop" on the big screen with all this innovative medical technology leaving them in total awe. For the younger generation there is the futuristic equipment used by Dr. "Bones" McCoy in the Star Trek TV series and movies. Little did those who watched the films and TV shows then, know that all of these "ahead of its time paraphernalia" would soon become part of their everyday lives. Future of Health Care Technology Advancement in health care technology is moving at a very fast pace in the world today and there are no signs that in the future it would slow down. Computers have provided technological advancements in every field, but in the field of medicine, this advancement has been very noticeable. Many have been witness to the numerous changes in health care technology in the last decades. Patients have noticed how with special software now available used to create and maintain paperless medical records has allowed for the immediate access to all their medical history.
