Solar Powered Air Conditioners are Becoming More Elaborate

airc

Air conditioners can consume an incredible amount of power. Between the electricity the compressor utilizes and the torque of the motor in order to spin the fan, your electric bill can skyrocket over the summer. In order to reduce the cost of this unit, some have installed solar panels onto the roof specific to the sole use of the AC device. However, innovative designs have made development of these units far more elaborate than in previous years.

Mobile Cooling – Many people like the idea of being able to maneuver a cooling device set on wheels in order to maximize the effect in any given room. Developers have created a small unit that can be rolled across the floor while being connected to a solar panel. With some of these smaller units, you can essentially place the panel in the window as long as the sun’s light can reach. These can be incredibly useful if you need a solution that can travel with you from one room to the next.

Ductless Heat Pump Units – Operating at 18,000 BTU, some of these ductless heat pump units can reduce power consumption by nearly 97-percent. Solar panels as well as the mini-split design allows for installation nearly anywhere. Once the sun light is minimal, the heat pump automatically switches to an energy efficient device taking its power from the grid. Although some of these are not 100-percent dependent on solar power or battery backups, the units can still reduce your day-time spending per kilowatt hour.

Hybrid Heating and AC – Some units have been developed to act as both air conditioning and as heaters in order to keep rooms comfortable year round. Although this isn’t necessarily a new idea, the addition of solar power to operate these units decreases your spending regardless of season changes. Some of these miniature HVAC systems can range from small 5,000 BTU devices to more powerful machines producing more than 40,000 BTUs. Depending on your own room requirements, hybrid systems can keep you cool in the summer and warm in the winter while using less power from the grid.

Central Air – Central air is an efficient method of keeping the home cool in the summer. Solar power adaptations have been created that can operate in a hybrid unit offering cool air as well as heat. Using energy efficient technology and including its own dedicated solar panel, these units are far less costly to maintain than the gird-dedicated counterparts of the past.

Do it Yourself Projects – If you can’t find something that fits your budget or your specific needs, you can always build one yourself. There are many different ways that these units can be assembled – most of them using upcycled parts from various machines. Your own imagination and skills with a soldering iron will play a role in how elaborate you make your own solar AC unit. You may even design something that is marketable to make a few extra dollars.

With each passing year, an innovative method is developed to include solar energy. Air conditioners, outdoor camping showers, ovens, toys, boat engines and more have been adapted to utilize one of the most abundant sources of power humankind has discovered. What was once an expensive addition for the upper class has decreased in cost to the point where nearly everyone can benefit in one form or another from solar energy. Imagine what will be developed tomorrow.

Electronic Medical Records and Personal Health Records

With the ever expanding Internet opening possibilities across various forms of business, we find ourselves in an age where information is readily available at our fingertips. Databases have been built regarding driving records, real estate, education, and more to provide a more efficient and less time consuming practice of data entry. Electronic medical records are no different and could be more important since the information is invaluable. There is a wide scope of possibilities for using electronic medical records.

1. Instant Sharing – In some care facilities, methods exist to share a patient’s information with another facility over the Internet in a different city. This could prove to be vital if the information requested pertains to a life threatening circumstance.

2. Clicks Away – With electronic medical and personal health records, the information is just a few clicks away. Instead of sifting through files and folders to find an individual’s information, it could just be a matter of entering a name search.

3. Billing – Most facilities have implemented some kind of a billing system for patients. Many of these billing applications can be used in conjunction with a medical record for further data analysis later on.

4. Web-Based – Data centers and the Cloud have increased efficiency of sharing patient information with practitioners around the globe. Some of these electronic records are based on the Internet alleviating a facility’s need for a sufficient data server. With the inclusion of images, x-rays, and more a server can get quite crowded with data in a largely populated area.

5. Cross Platform – Electronic medical and personal health records can be accessed across multiple devices. As some are web-based, a web browser on a tablet or phone would suffice. However, some of these EMR developers have made apps for Android and iPad for a more efficient tablet use. These apps connect to the database on the Internet without the need of a browser and all pertinent information can be viewed.

6. Prescriptions – Advancements in technology have allowed some of the EMR applications the ability to send e-prescriptions to participating vendors. Programs such as Practice Fusion incorporate a variety of tools to create greater efficiency in the facility including messaging, reporting, and billing.

7. Quick Entry – Many EMR programs allow a practitioner the ability to simply click on symptoms to build a record reducing the amount of typing. This could also reduce miscommunications and illegible comments about how an individual patient has been treated in the past.

The days of old where we cut down trees to create paper for our records is slowly coming to an end. It was a method that worked, but technology and the need for efficiency are growing ever closer to triumph over archaic methods of communication. With a little ingenuity and innovation, we could very well create a single database that can be used to provide every piece of information about a specific individual.

Why Iran is lost to the West.

mossadeq

Sometimes we need to stand back and look at the historical origins of current problems.

In 1953 the CIA and MI6 assassinated the democratically elected president of Iran Mohammad Mosaddegh because he intended to nationalize the Iranian oil industry. The coup, among other things, was and is a significant reason for regional war and fossil fuels issues. You may recognize the oil company that initiated the coup, it is now known as British Petroleum (BP).

Empire and Nationhood

  • ISBN-10: 0231108192

The sources used by Mary Ann Heiss in Empire and Nationhood are successful in providing credible background for her statements regarding British and American sentiments during the Iranian Oil dispute. The lack of sources from Iran means that it is a largely a two, instead of three sided account of the events. She creates a detailed picture of the negotiations from a western viewpoint using largely the correspondences of Great Britain and the United States while the viewpoint of the Iranians is pieced together from secondary sources and public announcements. The cultural bias of the western representatives is commented on, so although there is a record of Iranian negotiations, they are biased and often indignant descriptions by diplomats.
The overview of the Anglo-Iranian Oil crisis draws on many secondary works and a few books or articles written by people involved or living in Iran at the time. The secondary works are for the most part written by western historians whose titles do not suggest an evenly balanced perspective. For example the official history of the British Petroleum Company is cited a few times and many of the books are primarily concerned with the cold war. Iran was certainly important in the cold war but focusing on it might tend to show the perspectives of those fighting the war rather than that of Iran, which was a chess piece in the games being played between the US and the USSR.
The sources that contribute to the descriptions of the strained relations leading up to the rise of the nationalization movement and the rise of Mossadeq are a mix of British and American correspondences and books concerning the rise of Mossadeq and the political situation in Iran before him. This chapter, “too little too late” shows the greatest balance between eastern and western sources used. The difference is that the sources from the Middle Eastern perspective are written long after the events took place while correspondence on the part of the western diplomats give a more accurate sense of the feeling at the time. Authors whose names indicate Middle Eastern heritage are significant because they are referenced sparingly once Mossadeq is prime minister. This may have something to do with the secrecy Mossadeq afforded himself once in office. Also, the remainder of the book is largely an account of the negotiations between Mossadeq and representatives of England and the US. This means that presently we can look at the negotiations because there is a record of the internal consultations on the western end but we do not know the full extent of the pressure and constraints put on Mossadeq by political entities and public opinion. A dispatch from the state department to someone involved with debating Mossadeq on a key point shows the reasoning behind the American position while the reasoning behind the Iranian posture can only be guessed at.
Another reason for the one sidedness of the documentation is that for the most part, it was a Prime Minister talking to a diplomat who is already biased against the PM. Mossadeq had the power to make concessions so the political motivations behind his actions have to be derived from the situation in Iran. We have such a good record of the western motivations because American and British agents were constantly conferring with each other and their respective governments. It is unlikely that Mossadeq communicated with his advisors in writing and probably kept the details of his situation secret.
An important factor with regard to documentation that is not discussed in the book is the fact the Tehran at this time was chock full of spies. Channels of communication are never one hundred percent secure so information that was considered sensitive would be unlikely to be sent by telegraph for example. The author demonstrates the general fears of the US with regard to soviet interactions in Iran, but the specific threats, real or perceived, are not revealed. The author mentions documents relating to the MI-6 and CIA inspired coup that are withheld but only touches upon why the US thought the USSR would automatically take power in Iran if the economy were to fail. There is certainly logic behind the containment policy in Iran but because there is little mention of popular Iranian sentiment regarding communism aside from the actions of the Tudeh party, the policy seems to stem mainly from American paranoia.
The only primary sources that voice the position of Iran are the Correspondences between his/her Majesty’s Government in the United Kingdom and the Persian government, and related documents (concerning the oil Industry in Persia, February 1951 to September 1951) (Concerning the joint Anglo-American proposal for a settlement of the oil dispute, August 1952 to October 1952) The problem with these sources is that they were most likely documents that could be made public and were, if it suited a political aim. Most of the negotiations were done without the public knowledge or proposals were made informally at first with the reaction often eliminating the need to present them formally. What we can see in these formal documents are the last ditch efforts by Briton to save face by standing behind proposals they knew would be rejected.
It is clear that the United States was integral in the dispute between the Iranian Government, the AIOC and the British Government but the records taken from the national Archives verses the ones taken from the Public Record Office show that the available American records are more concise and therefore less accurate. The documents from the Public Record Office in England include minutes, memorandums and other immediate sources. These kinds of sources, if unaltered, are likely to be the most accurate and the most revealing. The record of the Secretary of Defense should in contrast be far less revealing and is certainly not cited as frequently as the Foreign Office correspondence. These American sources are not likely to contain information that could be considered inflammatory. That is to say that the United States would not be likely to make information public that could add to the hatred of the US by Iran.
The author does a satisfactory job of filling in the blanks created by the lack of Iranian primary sources. She gives a reasonable assessment of the political situation in Iran based on western perceptions that were probably fairly accurate because of the strategic concerns in Iran. The memoirs of Mossadeq may have helped to explain some of the pressures he faced in Iran but even a person’s memory of their own actions cannot be trusted as fact. While the author does not attempt to analyze individual Iranian sentiment for lack of material, it would seems possible to find a primary source written by an Iranian who was not Mossadeq or the Shah. She does a good job showing the shift from British to American domination of the Iranian oil as well as their reactions to the nationalist movement.

Siemens Performance on Renewable Energy Market

Guest post by Maria Kruk, an author for Patentsbase.com

Siemens is one of the companies, which are focused on the innovative fields, as well as on markets with a good potential for expanding. These features are essential for renewable energy industries. In this context, Siemens finds it as an attractive market to invest money and technologies. Production of renewable energy and electricity became one more industry the company works in, along with electronics, IT technologies, medicine and urban infrastructure. Siemens is interested in specific branches of renewable energy sector, related research and innovations, which, by the way, receive nearly 4 billion dollars annually. Energy-saving technologies are of big priority, being the company’s goal all over the world.

Siemens Wind Power is the most advanced alternative energy branch of the company. About 7000 wind power generators are operated globally with total capacity of 6000 MW. The statistics features that such energy production can provide for 7 million households and prevent 8 million tons of carbon dioxide emissions annually. Especially, Siemens is focused on European countries, putting its projects into operation in Denmark, Germany, Northern Ireland, etc. Much of attention was paid to company’s innovative project, executed in collaboration with Hydreo, – floating wind power stations that can alter their location in order to get matching air flows. In addition, Siemens is engaged in construction of such wind farms as Teesside (UK), Cape Wind and Block Island (USA), Meerwind Sud/Ost (Germany), Horns Rev II (Denmark) and may others.

Hydro power production is one more industry Siemens is interested in. To provide some details, construction of hydro power stations is more expensive, but energy prime cost is lower. Therefore, energy demand outranges company’s expenses on hydro power projects. Since late 1970s hydroelectric power has become one of the investment items of the company. To be more précised, Siemens AG started to supply generators to the biggest hydro power station in the world – Itapúa, on Brazilian-Paraguayan border. To date, Siemens deals with technological developments for small hydropower plants up to 30 MW, as well as with reconstruction of existing power plants. In fact, in recent years Russian rivers alerted an attention of company’s executives. Depending on the power plant, Siemens offers to equip the turbine with adjustable or fixed blades of all currently available designs. Technologies introduced by the company ensure a high safety margin of small hydroelectric power stations and low operating costs.

Naturally, solar power is a crucial part on renewable energy market, but not for Siemens as once could guess. The key thing is that solar power was much of company’s priority during decades, until the 2012, when Siemens refused to succeed on the solar power market. In particular, the company refused to manufacture solar panels m and to convert solar energy into electricity, mainly because of price pressure on the market. Since then wind and hydro power remain primary renewable energy targets of Siemens, which are promised to provide 30 per cent of energy worldwide by 2030.

Cloud computing and the wasteful excesses of data centres

Cloud computing and the wasteful excesses of data centres

 

With the rapid increase in the use of cloud services and the number of cloud service options available, more data centres have popped up all over the globe, bringing with them a higher demand for electricity. Recent reports by the Energy Conservation Bureau suggest that data centres now consume 3% of all electricity generated in the United States. A September New York Times article, “Power, Pollution and the Internet”, reports that data centres waste large amounts of energy, with only 6 – 12% of energy used by data centres going towards computing.

Data centres often consist of rows of servers, computers whose primary purposes are to process data. The heat generated by these servers can melt crucial computer components, risking data loss. As data centres have grown many now spread rows of servers over hundreds of thousands of square feet and utilize industrial cooling systems to combat overheating. Tens of thousands of data centres now exist to support the heavy demands of internet use, with many of the largest internet companies running servers at full capacity regardless of demand, resulting in the excessive wasting of energy.

There are ways to build more energy-efficient data centres. Providers can consider re-evaluating their redundancy, utilizing storage virtualization, consolidating their servers, and upgrading to energy efficient technology. Some data centres utilize their environment to cool their systems, such as a local waterfall or cold Arctic air. If clients outsource data centre management to high quality facilities that follow these practices, they can avoid forming their own poor management habits. Outsourcing can also save clients from having to upscale and downscale their own equipment to match the changing demands on their business.

Though outsourcing offers advantages, if large data centres are not optimally managed, these industry practices only contribute to more energy consumption. A large data centre is not inherently more energy efficient than a small one, and the spreading of load does not guarantee a reduced need for capacity. It stands to reason the cloud service providers need more spare capacity available to serve their clients than if clients operated their own facilities. Some argue that cloud services help to improve the situation, leading to a consolidation and centralization of computing among large, well-operated data centres. This is not necessarily the case.

Powering the internet is a very environmentally unfriendly prospect. Cloud computing presents a path towards improving the situation, but it is not a solution in and of itself.

Interesting Bio-fuel solutions

insert_pellets

Guest Post by Maria Kruk, an author for Patentsbase.com

Search of new renewable energy solutions has embraced most of the countries recently. Indeed, growth of oil and gas prices and shortage of fuel deposits contributed a lot in referring to alternative power facilities, such as solar stations, wind farms and tidal power systems. However, these are the prerogative of those lands possessing suitable climate conditions and favoring national policy. On the contrary, the other states have many benefits for biofuels production, converting wastes and unnecessary materials into promising energy resources. Some examples testify on how creative and effective new technologies might be.

Germany is a vivid example of how biofuels might invest in national energy balance. For several decades German scientists have been working on biofuel technologies, and some of the concepts alerted governmental attention. To date, economic discussions are engaged in related issues, which are focused on how to make biofuels cheaper.  One of the received results is directed on car fuels production out of agricultural and wood wastes. The released technology features synthetic gasoline made of sawdust and straw, including two major stages: gathering basic material straightforward on farms and timber factories and gasoline production on the plant. Its price is expected to be 0,5 Euro per liter and the first supplies are scheduled on 2012.

Wageningen University and Research Centre in Ukraine is working on the concept of thermal and electrical energy from biomass gathered in Chernobyl restricted zone. It is appropriate to mention that this country still copes with consequences of tragic events of April 26th 1986, when there was a huge explosion on the local nuclear plant. However, biomass is offered to be cultivated on the lands cleared from radioactive effects.  All in all, the idea of any activity in Chernobyl zone is quite unpleasing and it might influence negatively on reputation of Ukrainian businessmen. Many scientists conclude that this area should be a testing ground for scientific experiments and investigations for many decades in future.

In contrast, Ukraine can boast of certain biomass advancement. It is the first country in Eastern Europe to establish a production of mobile industrial facilities that convert organic wastes into fuel pellets. These biofuel complexes, called “Forward”, are embedded on the truck platforms. Forward’s average capacity is about 2 tons per hour. The other advantage of these mobile platforms is their cost, which twice cheaper than foreign equipment – 300 thousand dollars.

During recent decades many countries in Europe opened huge biodiesel plants, using different primary materials. One of them is located in Spanish port Ferrol with a total capacity of 200 thousand tons of biodiesel fuels per year. It produces biodiesel from refined and unrefined vegetable oil, mainly soybean and canola oils. Giant biomass recycling plant was put in commission in Kalundborg city in Denmark. This facility performs several important tasks, which include recycling wheat straw, corn stalks and cobs, sugar bagasse and grass; usage of waste steam in biomass production and manufacturing lignin biofuel. Palm oil and rapeseed oil and animal fats are used in three biofuel plants in Rotterdam, which belong to Neste Oil Corp (Finland).  Their total capacity is 800 thousand tons of biodiesel annually.

HIT Solar Cells

Cheaper Manufacturing for HIT Solar Cells

This is a guest post by Mathias Aarre Maehlum of  Energy Informative

Fraunhofer Institute for Surface Engineering and Thin Films IST in Braunschweig, Germany, has been working on making the manufacturing of HIT solar cells cheaper by engineering an improved coating process.

Hetorjunction with Intrinsic Thin layer (HIT) solar cells are currently one of the most promising new technologies in the PV industry. They have consistently shown high performance in laboratory conditions – in some cases up to 23% – significantly higher than the majority solar modules on today`s market.

Fraunhofer IST`s new way of producing HIT solar cells includes hot wires instead of the plasma-CDV process, which allows for cheaper mass production. The plasma-CDV process is dependent on large quantities of silane gas to function. Somewhere of 85-90% is lost through the process and becomes waste, which of course brings costs up.

By using the hot wire method “we can use almost all of the silane gas, so we actually recover 85 to 90 percent of the costly gas. This reduces the overall manufacturing costs of the layers by over 50 percent. The price of the wire that we need for this process is negligible when compared to the price of the silane” states Dr. Lothar Schäfer, department head at Fraunhofer IST.

The generators that power the manufacturing system are also ten times less expensive in terms of energy consumption than those that power the plasma CDV-process.

Even though the technology seems to have significant advantages over convetional ways of producing solar cells, it is still nowhere near being released on the market. It will likely be another three to five years until Fraunhofer IST`s new technology will be used for large-scale manufacturing of solar panels.

For more information on the new technology, check out the official press release.
