Prices for solar panels have fallen significantly in recent years. Increased mass production is, of course, the biggest reason for the declining prices, but better monitoring and less waste during the production process is also a strong contributing factor.
One of the methods to monitor the deposition of thin film, the basic material for manufacturing solar panels, is Reflection High-Energy Electron Diffraction (RHEED).
Sophisticated RHEED monitoring systems are used to ensure in real-time that the production parameters are followed. If needed, corrections can be made in a very timely manner and waste avoided. This kind of monitoring helps manufacturers to significantly lower the cost of thin film, which is reflected in the price of solar panels.
These days, making money online is one of the most hotly debated issues. Whereas many believe that buy cvv dumps online is the great way to earn money, others think allowing people to buy dumps with pin online is a better way to make money online. To the best of our knowledge, to buy dumps with pin is likely more beneficial than the former. This article will elaborate the reasons why as below.
To begin with, it is generally acknowledged that those who attempt to buy cvv dumps online with track 1 track 2 will eventually end up making money by using the cards generated from the data of these cvv dumps track at the pos machines at the time they pay the bills at the restaurant or convenience stores for instance. To do this, earners need to achieve high quality, accurate, up-to-date data. And of course, the great written cards machines like Msr. Furthermore, they need to understand deeply about how these data works with these machines. Then how the cards they are able to create match with the Pos machines at the place they use to pay. It is widely expected that these workers have to have a high end technology and deep understanding about sophisticated advanced technologies to make these things worked.
On the other hand are those who content that by choosing to buy dumps with pin online, people will have more chance to get more money by cash by withdrawing money at Atm machines instead of using at Pos machines like purchasing cvv dumps. By doing this, earner will need to buy a valid data of dumps track 1 track 2 in order to make physical cards then they can use it to withdraw cash at atm machines. Unlike buying cvv dumps online, they need another msr machine to write the physical cards. And also these machines and database of the dumps with pin track 1 2 are also far more expensive then to buy cvv dumps track online. Customers are able to purchase these stuffs on both dark market as well as the surface of the Internet. However, it is well-recognized that buying cvv dumps track from dark market is absolutely more reliable than any websites you find on Google. Simply because there are a numerous scammers, rippers always fake themselves as legit hackers to lure customers and cheat their money away. Still, there is a legitimate hacker who does sell these cvv dumps and dumps with pin track online through their auto shop online. They are a group of European hackers at legitdumps.ru .You can also reach them at their firstname.lastname@example.org. We wish you all the best for whichever decision you make.
Do you feel annoyed with the ads when you open a website on the internet? No matter how much you hate an ad that appears on the website or app, they are a way for companies and publishers to earn revenue and try to offer interesting products. However, sometimes there are some ads that are designed to appear in a very annoying way, leaving netizens even more annoyed and deciding to use ad-block that will block all ads without selective logging, which in turn creates good ads too.
On the other hand, for now some browsers are building on ad blockers into their proprietary software, and in April we’ve heard how Google can plan to do the same with Chrome. Good news for Chrome users, that if you hate ads and will love the offered solution, you’re lucky that Google Chrome will do that in 2018.
Have you ever thought before that Google Chrome can run Android apps?Ever, or not?In fact, Google Chrome can indeed run Android apps. Thatt way,Android applications can run on various types of platforms, including Windows without using the emulator.
Given by 2015, Google launched a tool called ARC Welder. This app is desiggned to allow developers to test their apps to Chrome. Actually ARC Welder has a purppose so that developers can create applications forr Chrome with ease,, but some of them use this ARC Welder to run Android applications easily.
Even very easy to run Android applications by using ARC Welder and also we can show you how. Quite simple and easy just by followingg the instructions beloww. But you need to note that some Android applications are nott fully able to run well with this tool.

Do you remember the movie Superman who was chatting with his father using holographic projections that data is stored in a crystal prism? Turns data storage technology uses the crystal Superman is no longer just a fantasy. A group of scientists from the University of Southampton have made a big step in the world of data storage that can last for a period of up to billions of years. By using nano-glass structure, the researchers managed to develop the process of recording and retrieval of data through technology 5-dimensional digital data femtosecond laser.
Nano-crystal technology used in ‘flash’, making him capable of storing up to 360 terabytes of data! Thermal endurance is able to reach 1000 ° C, and even durability to survive until the time is almost unlimited if stored at room temperature (13.8 billion years at a temperature of 190 ° C). With great technology that makes us into a new era in data storage. With the great ability, storage using these crystals would be very suitable for use by agencies with large data storage requirements for long periods of time such as the National Archives, libraries, museums, or also other major companies are similar.
One of the world’s most important documents that have been stored in the disk, these crystals is the Universal Declaration of Human Rights (UDHR). This document recorded using ultra-fast laser, produces short light pulse intensity and super fast. The document is written on three sheets of separate nano crystal structure thickness of 5 micrometers. This technology stores data through a five-dimensional (5D) parameters including height, length, width, orientation, and position of the light pulse is recorded in the nano-crystals. Read more
Awareness of environmentally friendly energy use today is increasingly flourishing. Accompanied with the low price of renewable energy sources such as solar panels one of which also contribute to the renewable energy campaign. Example one concrete step movement use of renewable energy sources conducted by Cochin International Airport in southern India. Seventh busiest airport in India was crowned as the first international airport which is 100% of its electricity needs met by solar panels.
To meet the electricity needs of the airport, the airport management pointed to a German company, Bosch, to build a solar power plant on vacant land measuring 45 acres located near the international cargo terminal of the airport. With a total of approximately 10,000 solar panels are used, this self-contained power plant capable of supplying 48,000 to 50,000 kilowatts of electricity to meet the electricity needs of the airport each day. Even the amount of energy is still surplus and still able to support the needs of the electricity network in the area around the airport.
Construction of solar power plants this independent cost US $ 9.3 million, equivalent to 121 billion rupiah. With the cost of the airport management hoped would never buy electricity from its India up to six years into the future. In addition, the solar power plants contributed to reducing carbon dioxide emissions of 300,000 metric tons of coal-fired power plants of up to twenty-five years into the future.
Since Pluto is no longer acknowledges the real planet, has several times found “dwarf planet” Pluto have similar orbits beyond Neptune. Dwarf planet is a term for a planet that does not meet the third criterion of three planets criteria set by the International Astronomical Union.
One interesting thing is that apparently in addition to the dwarf planet Pluto, beyond the orbit of the planet Neptune lies a giant orbit space contains many objects that scientists have nicknamed him the Kuiper Belt. The Kuiper Belt is an orbit of ice in which there are few objects of space that has been identified by scientists as a dwarf planet, like Eris, Haumea, Makemake, Sedna, Quaoar, 2007 OR10, and of course Pluto which has been first discovered in 1930 by Clyde W. Tombaugh. Even recently identified a new dwarf planet that orbits super far exceeds other dwarf planets that travel is about 700 Earth years. Planet is still named interim RR245 2015 is estimated to have a diameter of only 700 kilometers, there are still much smaller than the dwarf planet Pluto has a diameter of 2371 km.
The discovery of the dwarf planet 2015 RR245 which was first identified in February, is one of the results of surveys, titled Outer Space Solar System Origins Survey (Ossos). Ossos so far been detected at least 500 space objects in the Kuiper Belt Area. However new RR245 2015 are identified as a dwarf planet. Astronomers will continue to observe planets that orbit will reach its closest distance to the sun in the year 2096, in order to obtain data that is more accurate.

The good news for the provision of alternative energy sources in the world. Fusion energy is likely to be soon used in small-scale power generation. Fusion energy used is generated from a variety of chemical reactions involving water. This means that humans will get one more environmentally friendly energy sources and cheap. A study conducted at the University of Gothenburg is trying to produce generator-powered heaters and electric generator energy of nuclear fusion which involves water as basic materials.
Nuclear fusion energy is the energy that results from the union of two nuclei to form a larger nucleus. The unification of the two nuclei into one atomic nucleus releases a huge amount of energy called nuclear fusion energy. For those of you that had not been aware of the existence of nuclear fusion energy in the universe, the stars in the sky caused by the release of energy from nuclear fusion “star body”. Hydrogen bomb explosions also occurred due to the release of nuclear fusion energy. We know that the hydrogen bomb is one of the most powerful bomb ever made by man. This indicates that nuclear fusion energy has enormous power.
Research new types of nuclear fusion process is capable of producing nuclear fusion energy free neutron, and also capable of producing heavy electrons (muons) because this energy is produced from nuclear reactions taking place in the ultra-dense hydrogen atom (ultra-dense heavy hydrogen).
As described above, the heavy hydrogen is found in abundance in the water, both rivers and oceans. Heavy hydrogen can be extracted without the process is too complicated. For large-scale reactors may be required handling radioactive heavy hydrogen (tritium), but for small-scale reactors it is less needed. Process-based nuclear fusion of deuterium is also capable of producing very large electric energy in a short time. Reminded once again, this fusion process does not produce neutrons that are harmful to living organisms and can produce muons, heavy electrons, which have a rapid onset and can be instantly transformed into ordinary electron. This means that heavy electrons produced will soon re-cycle itself into ordinary electrons and does not produce a new particle that may be harmful to the environment. The most important thing is not a large-scale reactor is needed to facilitate this process of nuclear fusion.
A revolution in technology alternative back unsolved. A group of mechanical and Australian scientists who are members of the Victorian Organic Solar Cell Consortium has announced that they will soon be marketing a new technology in producing solar panels. The technology they create does not require a complicated way to produce solar panels, all they need is a printer! Yes, a printing machine that will quickly and cheaply can print solar panels onto the surface of any object, especially plastic! Naturally this innovation will decisively, sooner or later, push down the price of conventional solar panels are quite expensive because the manufacturing process is more complicated.
That this new technology can easily print solar panels directly on the sheet of plastic or other material. In fact, it can also be printed directly onto electronic equipment sorts of laptops and smartphones, so they get a renewable energy source at any time.
Print it out on a plastic sheet is approximately equal to the process of printing banknotes. Connect it with other electronic equipment as well as easy as installing the battery. It’s very cheap! The interface is also quite different from the conventional silicon solar panels. More detailed printout solar panels that will appear transparent, thus making it very suitable to be applied to building homes and buildings.
The next task is to improve the efficiency of the panel. We should be able to create a ‘printing ink’ which is able to absorb more solar energy. We are sure to be able to do in the next few years.
It is undeniable that an electric generator is required to have an excellent cooling system to remove heat created therein. If the heat in the generator is not immediately removed, he will directly damage the generator itself. Excessive heat can damage the coils in the extreme rotor, stator, it will even burn components of the generator.
Hydrogen gas is the best choice to replace the air as the cooling medium generator primarily on large-sized generators. Hydrogen chosen because its characteristics were excellent when used as a coolant, call it a high thermal conductivity (0.168 W / m · K), its density is very light, and also a high specific heat. With these characteristics, making hydrogen 7-10 times better than air conditioning if used. This can be likened to generate the same electrical power, air-cooled generator will be sized 7-10 times greater than the hydrogen-cooled generator. Therefore, for large-sized generators, hydrogen cooling systems will become more economical than using the air conditioning. Actually, helium gas has good thermal conductivity as well (0.142 W / m · K), but because the price is much more expensive than hydrogen, then it is not used.
Generators are formed from millions of winding wire arranged in a coil on the two sides of the different sectors the rotor and stator. The coils will generate very high heat during generator operation. Hydrogen as a coolant to flow generator will envelop these coils, absorbing heat, and throw it in the cooling heat exchanger. There are two types of hydrogen in the generator cooling system commonly used is hydrogen cools the generator rotor stator at the same time, and generator with hydrogen cooling for the water on the rotor and stator side. Generators that use hydrogen coolant in the water on the rotor and stator usually large and Megawatt electricity generating over 500 MW. Read more
A quite revolutionary innovation made by electricity giant General Electric, known as GE. GE is currently conducting research to build a mini power plant the size of a desk, but was able to support at least 10,000 households. Mini turbine is mentioned only a size ten times smaller than the steam turbine with the same energy output capabilities.
A unique feature of this turbine is the driving fluid are not uncommon. Not water vapor, not wind nor water! The turbine uses the fluid carbon dioxide as an energy transfer medium. Carbon dioxide is heated to 700 ° C at very high pressure to supercritical prior to entry into the turbine. Carbon dioxide out of the turbine is cooled and the pressure is increased again before going back past the same cycle.
Technology use of carbon dioxide into various key advantages of this turbine. First advantage is their small size, outsize steam turbines up to ten times smaller. From these advantages alone deliver the turbine further advantage to the startup much faster than the steam turbine. Turbine CO2 only takes one to two minutes to reach full rotational speed, compared with the steam turbine which takes up to half an hour to turn it on. In terms of efficiency, this new type of turbine is able to achieve up to 50% thermal efficiency, which is certainly far enough steam leaving the turbine efficiency is only able to achieve 45% only.
To date, still building a small-scale CO2 turbines capable of generating power up to 10 Megawatt. But planned to be built turbines with power up to 33 Megawatt, power highly enough to support approximately 10,000 households or practically equivalent to a fairly large city. Explained that the main thermal energy sources that will be used later is solar thermal, nuclear or even burning. Technology uses molten salt heat storage will also be used so that the heat from the source can be stored for use at a difficult time as a heat source in winter.
