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.

As we know that the sun is the center of the solar system in the Milky Way. The sun becomes a source of life for living beings living on the earth. There are many benefits of sunlight are used by humans and other living organisms. The development of technology in human life, the sun is used in various fields. Well so let us know what are the benefits of solar energy in life?
ADVANTAGES OF SOLAR ENERGY FOR LIFE
- As a Solar Power Generation
The continued development of technology developed by humans, the source of solar energy can be used for solar power generation. The source of the sun’s heat can be converted into electrical energy with the media devices called solar panels. The unique of solar energy is converted into electrical energy that is safe and friendly to the environment without creating air pollution. Solar energy is called a renewable energy in the sense that as long as sunlight still there, then it can still be used.
- As manager of the Solar System
The sun is referred to as the center of the solar system, and therefore the planet and the satellite will evolve to include the earth rotating around the sun. This is because the sun gravitasu force that can pull up to the planet’s planets revolve around the sun. With so then formed the solar system which is called the Milky Way.
Solar cells are devices that can light from the sun directly into an electrical energy. Solar cells are also called the media to maximize the potential of energy derived from sunlight. Although used in generating electricity, the energy of the sun can also be maximized heat through solar thermal energy. Solar cells are often used by various companies to generate electrical energy.
When getting sun exposure in general of the solar cell can produce a dc voltage of 0.5 to 1 volt, and also short-circuit currents. Large voltages and currents are not enough untu various applications. So that in general a number of solar cells arranged in series to form a solar module. In general, solar modules consist of 28 to 36 and the total solar cell can produce a dc voltage of 12 Volts in standard light conditions. The solar modules can be combined in series and parallel manner to increase the voltage and current on the corresponding output power is required in certain applications. Then how the workings of the solar cells that can harness solar energy into electrical energy? Consider the review below!
HOW SOLAR CELLS
Conventional solar cells work by using the principle that such junction pn junction between p-type semiconductor and n-type. Semiconductors comes from bonding atoms have electrons as a constituent base. Each semiconductor has its own advantages such as n-type semiconductors that have excess electrons negative charge, whereas for p-type semiconductor has excess positive charge holes. Read more
Scientists believe that it could create an artificial sun, as a substitute solar power to illuminate the Earth, disclose it and sure can convert sunlight into laser.
Currently, scientists are building a suspected satellite designed to take the sun, and gather to convert. Once the conversion is done, then the beam will be re-fired it into energy or laser beams to Earth.
On satellites built by the scientists, sunlight is collected via a mirror which is then converted into a laser beam. System of semi-conductor devices embedded in the body of the satellite, then worked for the laser fire to Earth. Read more
What the Industrial Technology and Industrial Engineering? Technology is a discipline that, if adopted by someone then that person is called “technology”. Industrial Technology is a discipline that is necessary for man to be mastered one or all of the many things such as; designing, managing, analyzing, and other related matters within the scope of “industrial process”.
Rather tricky to distinguish between technology and engineering. “Technology” relating to discipline, components and products. Industrial technology means is the discipline of components, products and systems are used. While the “technique” is related to someone who is an expert with the methods used. More specifically, the keyword “industrial engineering” is productivity, effectiveness, and efficiency
Techniques associated with education and career. Career can be an industrial engineering student after graduation is production engineers, supply chain managers, operations analysts, quality engineers, and information system analysts. Cultivated fields are also very spacious, all kinds of businesses, companies, and governments seeking to improve performance and reduce costs requires an industrial engineering. In addition, many industrial engineering graduates who make their own business or go into consulting.
An advanced tool invented by a German company called Sunfire are able to produce fuel without having to do the drilling process first. Instead, the machine can produce fuel only by using water as the main ingredient.
The machine utilizes a process called Fischer-Tropsch. The process also serves to convert carbon monoxide combined with hydrogen into liquid hydrocarbons. This machine also uses materials such as water and carbon dioxide in order to obtain hydrogen and carbon monoxide.
There are several steps that can be done to be able to produce the fuel. First, the water must be evaporated first and subsequent oxygen and hydrogen is separated into solid oxide electrolyser sell. Hydrogen in this process is used to convert carbon dioxide into carbon monoxide which then combined with hydrogen and finally produce hydrocarbons.
In the UK, the government participated strive to reduce fuel consumption. In fact, they recently launched its first environmentally friendly buses that use fuel from human faeces.
The bus was going to go and serve the passengers who want to travel between Bristol to Bath. The bus is actually completely using fuels from bio methane produced from waste processing and human waste in Bristol. By doing so, these buses can reduce the rate of fuel use in the local area.
The purpose of making this an environmentally friendly bus itself is to reduce the level of pollution in the city center. By using bio-methane fuel, these buses produce greenhouse gases 30 percent less than diesel buses. If you are concerned with the odor generated, just take it. The gas used was purified so odorless.
Currently humans have to think to use alternative energy , such as solar power , wind power, biomass power, geothermal power, and other reserves as the depletion of natural resources, especially petroleum . The one that is now so much choice is solar power .
Since the last few decades, solar energy has been used in various countries. If properly exploited, solar energy predicted to provide the needs of the world’s energy consumption. Solar energy has its advantages, which can be used free of nature, as well as CO2-free making it environmentally friendly. With a tropical climate conditions sunlight throughout the year, Indonesia also has the potential to generate significant solar energy. Read more
