Solar Thermal Technology on an Industrial Scale

Solar Thermal Technology on an Industrial Scale

Our sun produces 400,000,000,000,000,000,000,000,000 watts of energy every second and the belief is that it will last for another 5 billion years. The United States reached peak oil production in 1970, and there is no telling when global oil production will peak, but it is accepted that when it is gone the party is over. The sun, however, is the most reliable and abundant source of energy.

Solar Thermal vs. Photovoltaic

It is important to understand that solar thermal technology is not the same as solar panel, or
photovoltaic, technology. Solar thermal electric energy generation concentrates the light from the sun to create heat, and that heat is used to run a heat engine, which turns a generator to make electricity.

The working fluid that is heated by the concentrated sunlight can be a liquid or a gas. Different working fluids include water, oil, salts, air, nitrogen, helium, etc. Different engine types include steam engines, gas turbines, Stirling engines, etc. All of these engines can be quite efficient, often between 30% and 40%, and are capable of producing 10s to 100s of megawatts of power.

Photovoltaic, or PV energy conversion, on the other hand, directly converts the suns light into electricity. This means that solar panels are only effective during daylight hours because storing electricity is not a particularly efficient process. Heat storage is a far easier and efficient method, which is what makes solar thermal so attractive for large-scale energy production.

Heat can be stored during the day and then converted into electricity at night. Solar thermal plants that have storage capacities can drastically improve both the economics and the dispatchability of solar electricity.

Competing with Fossil Fuels

Solar thermal power currently leads the way as the most cost-effective solar technology on a large scale. It currently beats other PV systems, and it also can beat the cost of electricity from fossil fuels such as natural gas. In terms of low-cost and high negative environmental impact, nothing competes with coal.

But major solar thermal industry players such as eSolar, Brightsource, or Abengoa, have already beaten the price of photovoltaic and natural gas, and they have plans to beat the price of coal in the near future.

With an increasingly industrializing planet, the leaders in solar thermal technology have an ever-growing market. The issue is, and will always be, how to make solar thermal technology more economical. There are currently two methods for solar thermal collection. The first is line focus collection.

The second is point focus collection. Line focus is less expensive, technically less difficult, but not as efficient as point focus. The basis for this technology is a parabola-shaped mirror, which rotates on a single axis throughout the day tracking the sun. Point focus technique requires a series of mirrors surrounding a central tower, also known as a power tower. The mirrors focus the suns rays onto a point on the tower, which then transfers the heat into more usable energy.

Point focus, though initially costlier and technically more nuanced, outshines line focus when results are concerned. The point of focus in a line focus mirror array can only reach temperatures around 250 C.

That is a sufficient temperature to run a steam turbine, but when compared to the 500 C
and higher temperatures that point focus can reach, the extra effort and cost is balanced out by its greater efficiency capability. High efficiency matters because it drives down both the land usage, and the effective cost per kWhr of the plant.

Major Solar Thermal Players

Spain and Australia are the current leading countries in solar thermal energy production. Spain already produces a large portion of their electricity though their solar thermal facilities, some built by solar thermal powerhouses such as Acciona and Abengoa the creator of the PS10 and soon PS20.

The California based solar thermal company, eSolar, and the Israeli company, Brightsource, are fast growing competitors. Abengoa is opening the first power tower to be used for commercial energy production. eSolar is working with Southern California Edison to use solar thermal technology to generate 245 MW of power. Similarly, BrightSource has contracts with
Pacific Gas and Electric Company to bring even more solar thermal generated power to California.

Land Requirements

Another challenge for solar thermal is the amount of space required for efficient production of energy. Not only space, but space that gets a consistent amount of direct sunlight. Solar thermal power plants typically require 1/4 to 1 square mile or more of land. One silver lining of global climate change and human impact on the land is that more and more farmland is becoming unsuitable for agricultural production. This land, presumably originally chosen for its sun exposure, begs to be used for solar thermal energy production. Utilization of desertification can prove to be a boon for solar thermal real estate procurement and growth.

With solar thermal technologies being developed and advanced by companies such as eSolar,
Brightsource, Abengoa, Acciona, Ausra and Schott Solar, the world has a new alternative. The benefits of eliminating coal from our energy diet are many. By not burning fossil fuels, countries can be truly energy independent.

Also, by limiting, and hopefully eliminating, carbon emissions, a nations pollution
will not be windswept into another nations territories, further cementing the concept of
independence. Solar thermal plants are being built around the world, and many new planned plants are in the works.

Solar thermal is the current solar electricity cost champion, but more improvements are needed to beat the cost of the lowest-cost fossil fuels in a legislative climate without subsidies or carbon taxes. will teach you how to build solar & wind power systems for
your home within a weekend.

New Technology for Hair Loss

Looking for advanced and affordable hair growth technology? Well, you are not alone.

Reviewing Options Available

With cases of hair thinning and hair loss on the rise due to many factors, today there is a marked interest in solutions for it. From medicines to cosmetic treatments, available options are indeed endless. As every individual is different, causes too vary from person to person. Understanding the underlying cause for hair thinning and hair loss can help in controlling further hair loss.

Today, many companies offer effective hair growth technology. Leading Web sites offer a wide range of products to arrest hair fall and enhance hair re-growth. Categories on such websites usually include:

Treatment offered, along with details on what to expect from that treatment, as well as a listing of ingredients used;
Hair-related information, such as causes for hair loss, kinds of hair loss, understanding hair, tips for attaining healthy hair; and
Information on purchasing treatment- and shipping-related details.

Using advanced techniques and quality ingredients, established hair care brands now offer the latest hair growth technology.

Understanding Hair Loss

There are many causes for hair loss that may contribute, either singly or in combination, to a thinning pate. Common causes for hair loss are:

Hormonal imbalance
Inflammation of the scalp
Hereditary and genetic reasons
Psychological factors
Use of strong products on hair

While the above are the most common reasons for hair loss, there can be several others.

Technology To Recover From Hair Loss

Best names in the field of hair loss treatment make use of the latest hair growth technology. In addition to offering products manufactured through cutting-edge technology, established companies also ensure that their products are extremely safe and without any side effects. Hair-related technology can be classified under broad categories of: technology for hair loss, technology for baldness and technology for thinning hair. With leading companies hosting detailed information on their Web sites regarding the technology used for hair loss, baldness or thinning hair, the hair growth technology today has become more accessible. Offering effective treatment through herbal-base products, companies assure results in shortest time periods. Using high-quality herbal products, you may hope to see a difference in just half-a-month.

A latest technology to be launched in the market is the technology involving the use of penetrating peel. It can assure effective, noticeable results within just three months. As a solution promoting micro circulation and helping in the dilation of capillary vessels, this technology has been observed to be effective in many cases. The process includes two simple steps: dissolving the build-up of sebum that accumulates in sebaceous glands connected to hair follicles, and penetrating deep into the scalp to enable hair follicles better absorb nutrients for growth. As sebum build-up can cause infections and hamper circulation in the scalp, penetrating peel is the hair growth technology that strikes at the root of a common cause for hair loss and thinning.

Stewardship, Technology, And The Church

When it comes to stewardship and technology in the church where do you draw the line? At what point do you say yes to new technology and at what point is it a waste of money? Will someones eternal destiny really be determined by the type of microphone a singer uses? Will the lumens and contrast ratio of your projector really bring someone lasting peace? Will the quality of the lighting allow Gods Spirit to do what He pleases in someones heart? I have wrestled with these questions and more in my 18 years of ministry.

I started running my church sound system when I was in high school. I never had formal education in that area but my dad had volunteered in the sound booth when he saw that it was too much for the custodian to handle by himself. No one should have to do it every week with no break. I hung around enough to become familiar with where the cords get plugged in and what the knobs and faders did. Within a couple of years I was running the sound system myself for two of the churchs three services on Sunday.

In my next church I started experimenting with theatrical lighting. The budget for this was $100 per month but I was rarely allowed to spend it. It just wasnt the top priority for a new church. As people saw what I was able to do with lighting they saw more of a need for it. It really can set a mood. When the lighting is just right you just stop and admire the beauty of it all and praise the God that made it possible. But enough about sunsets and full moons, lets get back to sound. As I write this on my laptop on my backyard swing I am enjoying the happy sounds of my kids playing, the trickling of water in a nearby garden pond, and a neighbor mowing the lawn. Well, two out of three isnt bad.

When the sound is clear and loud enough, but not too loud, it is very enjoyable. The message, either spoken or sung, doesnt get lost as easily when there are no distractions. Quality sound reinforcement is necessary in larger rooms. Jesus didnt use an amplifier, so why should we? Jesus also didnt use a telephone. I guess we should get rid of those too, huh? There are many technical tools that enhance our ability to get a message delivered, whether the audience is in the room or on the Internet. Some of these tools are being used very creatively and effectively in the church to enhance the mood and create a receptive attitude in the listener. But have we gone too far? Is the message second place to the delivery of that message? Are the technical tools of ministry becoming technical toys used for enjoyment?

Can we justify spending $500 for a microphone when a $400 microphone will sound the same to 95% of the audience? Could we feed a hungry family with the difference? Can we justify a $5000 moving light fixture when two $2000 units will do almost as much? Could you pay someones medical bill with the difference? Are we called to be different from our world, or the same?

I love technology. I love the things it can do. I love good quality sound and lighting. I love to edit videos and wow an audience, mix it with the right music and touch people emotionally. I love the feelings that technology can bring out. But I love people more. I love Jesus more. Where your money is your heart will be also. I challenge all churches to consider doing this: For every dollar you spend on technology, put a dollar in the benevolence fund to take care of the needy. When we truly meet the needs of people in all areas of their lives the feeling they get on Sunday just may last longer than the final song, the last lighting cue, or the ending PowerPoint slide.

It all comes down to balance. When technology is used in the church the results can bring people closer to God. Or it can bring people closer to technology. Like a loaded gun, technology can bring a good result or a bad result depending on who uses it and for what purpose. Make sure you understand what the technology will do and why you need it before spending the money. If it will enhance your praise and worship of God then it is good stewardship. If it helps you meet the needs of people it is good stewardship. Remember to keep all things in balance. As Ryan Hodges said in Church Production Magazine, Good stewardship isnt about how much money you save, but how much money you dont waste.

uses of GPS Technology for Consumers

GPS Technology is now widely used in consumer devices. The technology allows us to pinpoint the exact location of anything that it is attached to. The biggest use for this is technology is assets that move or tracking people (for legitimate reasons of course!)

More consumers are using GPS Tracking Devices each and every day. The range of applications that the devices are used in seems to be growing, although the general trend is that it is attached to non static objects, generally of value.

Here are 5 different consumer uses for GPS Tracking Technology :

1.Cars and Vehicles

One of the most common uses of GPS Technology is vehicle tracking. With a small device fitted to any vehicle it is easy to monitor the exact location of the asset. This means that if you vehicle is lost or stolen you can easily retrieve it. In some circumstances it may even help you locate your parked car if you have forgotten where you left it – it does happen!

2.Tracking Loved Ones

Kids out playing around the estate or at the local playground? With a discrete GPS Tracking device you can monitor the location of their whereabouts which keeps your peace of mind at rest. WIth certain GPS Tracking systems you can also set up boundaries so if the GPS Tracking devices passes the boundary it signals an alarm or alert.

3.Tracking Pets

GPS Technology can be used both on dogs and cats. How often have you wondered where your cat gets to at night? With a GPS Tracking device you can monitor its exact location and map out its nightly route. If you have a dog that you often let off the lead, you know how quickly they can react to a scent and often forget about who they are with or where they are. Its easy for them to get lost quickly. With a GPS Tracking device fitted to the collar of the dog you can easily locate and retrieve your best friend!

4.Remote Assets

Remote Assets are ideal candidates for GPS Tracking devices. Do you own a boat or a Caravan that is often left unoccupied for large parts of the year? With a GPS Tracking device fitted you can keep a third eye on any unexpected movement of the asset which helps to you to react quickly and track down the exact location of its whereabouts.

5.Sports Events

OK, not all sports events benefit from the use of GPS Tracking devices, but remote sports such as orienteering or mountain trekking certainly can! If your loved one or family member is taking part in a remote trek around a mountain range what better way to keep in touch than knowing exactly where they are. Whats more, some GPS devices also come with the ability to communicate with each other, although these are generally more expensive than standard tracking devices.

All in all, GPS Tracking technology can be used to trace anything that moves. Usually consumers will attach the technology to something of value. There are many more potential uses than the 5 mentioned above, but these are generally the most common.

How Vertical Search Plus Semantic Technology Is To Change Digital Advertising

A lot of us would notice that it used to be, in marketing, we were looking to attract a big audience as we can. But right now, effective web marketing would rely on centering on the people who would be likely to acquire our merchandise or book the service at the time of peak interest.

History has informed us that through time, media fragments are placed in particular areas of interest. Remember a time where there had only been three TV stations? Now there would be multiple channels centered on interests. Do you recall a time there were only three TV stations? Now there would be multiple channels devoted to interests including cooking, pets, travel, sports, history science plus channels that serve micro-interests. In a similar sense, online content typically would show up on sites that revolve around particular areas of user interest. Internet search would also be divided into particular verticals, in spite of the omnipresence of broad search engines including Google and Bing or Yahoo. Five years past, users would place keywords into a search engine query; but now they go directly to the preferred content sites to get relevant information.

Publishers are still struggling though to keep the users on the sites, as a lot are facing an exodus to the Google toolbar. Publishers have stated that anywhere from 25% to 50% of outbound click from sites are about to have an outside search engine. Even worse, the publishers would need to pay the search providers for the clicks to get back the users. In a lot of cases, Google would monetize the publisher content in a better sense than the publisher itself.

It is a good thing new search tools have come up to aid online publishers plus marketers to connect users to the content, products plus services they want in the areas of interest. Semantic technology would be a representation of the forefront of the search experience. In place of relying on keywords, semantic search would actually have a basis on concepts, and would be more likely to comprehend the intent of the searcher.

Semantic technology would perform a better job compared to traditional search platforms for matching relevant advertisements to online content. As it is conceptual compared to literal, semantic technology would be able to match ads in a manner that would be limited by keyword algorithms.

Vertically centered semantic search would be a representation of an improvement in online experience for the site users, marketers and publishers. Users may quickly locate information on the topics plus subjects they would be passionate about without having to leave their desired sites. They are presented with ads relevant to them, compared to the ubiquitous links for mortgage refinancing plus teeth widening services. Of course, publishers would be keenly interested in manners to enhance user experience, however semantic search would make new revenue opportunities for them too.

Search result pages would come up with incremental page views, which the publisher would utilize to sell more units of display advertising inventory, plus to bring in more advertising revenue from high response semantically matched ads. Perhaps, in a more significant sense, search technology would give a way to make more engagement with users, keeping them on-site longer than surrendering these to an external search engine or a toolbar.

For online marketers, the semantic vertical search would give a lot of benefits. It would satisfy demand for more clicks, put up brand reach and ensure placement next to relevant content, making a yield of better response rates. Semantic search advertising would not be based on keywords, unlike the regular run of the mill process enhanced by KeywordSpy-so it would not need complex keyword bidding strategies and may be implemented quickly and easily.

As use of semantic technology is widely adopted, semantic search as will become a necessary part of the company’s marketing recipe. Companies which recognize and take advantage of semantic search now will be ahead of their competition, as search engine marketing continues to eveolve.

Wifi Technology Has Shifted The Lives Of The People To New Visions

Technology has changed the direction of the lives of the people and people are also keen to use the new technologies in their lives. New communication devices have converted the world from distanced places to a global village. In the recent past, the use of wire for data communication is a necessary component and without wire electronic communication is not possible. However, with the innovation in technology, the use of wire may be of no importance. New technology which has shifted the trends while using the communication devices is called wifi technology and with the use of wireless signal strength meter technology people have no need to use the wire at surrounded places.

In these days, most of the communication devices have contained the facility of wireless technology for the users. Wireless technology has given the opportunity to the users to use the products on compatible basis. However, the wifi technology has based on the strengths of the signals and for the quality communication people have to control the strength of the signals with the help of meters. Wifi is a technology which is compatible for local area network with the help of radio signals for communication of data.

In the technology, the strengths of the signals have managed with the help of wifi signal strength meter for effective working of the network. When people are willing to use the wireless signals to some extent on wide area, they have to take the facilitation from the wireless strength meter. Wifi technology has given the freedom to perform their communication tasks at different places without the requirement of the wire. For the purpose, companies have to take the rotor for signal capturing at different places.

With the growing competition in the electronics products, companies are striving hard to take the edge from the market by introducing some thing new for the customers. At present different mobile companies have given the facility of wifi technology in their cell phones and people are able to communicate with the use of the technology in the mobile phones. However, for the proper coverage, people have to take the help by purchasing the wireless strength meter to enhance the area of converge.

Technology And The Amish – A Marriage Of Convenience

Can you imagine a life without the telephone? Or without electricity, or heated water in winters and the cooling influence of an AC in summers? Difficult, if not impossible. Yet there is a traditional society which shuns the use of these very symbols of a modern world and stick to their beliefs of simple living and high thinking. Living in the midst of the chaos of the modern world, the Amish clan presents a calm -No, thank you, but we are doing just fine’ rebuff to the comforts of modern technology.

The reason why the Amish shun technology lies in their religious beliefs. Known to lead a reclusive lifestyle due to their religious restrictions, the Amish are an ascetic, reclusive group of people who try and keep their distance from the trappings of modern life. Not that technology would make their life less comfortable, but mainly it is seen as an affront to well established traditions and a simple and rugged life.

Take the use of the telephone. The small little instrument is a symbol of the progress man has made in the field of communications over the past centuries. The shunning could well be a result of the belief that widespread use of the telephone will lead to outside influences creeping in, and hence spoil the purity of their culture. The society, however, does not prohibit the use of modern technology where it becomes essential- for instance, calls may be made and received for business purposes, but only if made from a booth outside the home. The idea being to avoid its influence on the traditional household lifestyle, it is not allowed inside the home.

Another reason for the shunning of technology is the perceived differences it is likely to bring within the society. While current following of traditional beliefs results in a nearly equal society, the adoption of modern technology and its derivatives is bound to create different income levels, which would further lead to competition and the will to outdo the other. Both aspects are against the very essence of the movement, which has an equal society as its foundation.

Where technology does not preclude contact with the outside world, it may sometimes be used. Thus you are unlikely to find a television due to its perceived corrupting influence, but in a curious adaptation to the need of the day, some electric machines may be used, provided, firstly, they do not depend on outside electricity, and secondly, have a human element attached to it. An electric grass mover may be used, for instance, but only if it is to be pulled along by a human. Similarly, a wood carving machine may be used to make the basic structure of Amish furniture, but the final finish would still have to be done by the carpenter’s hand.

The simplicity would have to be retained, and you are unlikely to find too flashy a design in Amish handcrafted furniture. Tradition is of essence here, and it may take days to make a single piece, yet technology will only be used where it does not interfere with the cultural requirements. Even then, you can be reasonably sure that whatever the quantum of electricity used, the timber for the Amish made furniture has probably been cut on a diesel run generator rather than the regular supply!

Though it may not be the ideal way to live for most tech junkies, the Amish way of life does offer a few lessons in simple living. Talk to an Amish gentleman or a lady, and you will find a person unhindered by the shackles of modern trappings, happy in the simplicity of his or her life.
