Nuclear Reactor Made From Water

Reaktor Nuklir Berbahan Baku Air

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.

Solar Panel Technology Revolution

Solar Panel Technology Revolution

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.

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.

Hydrogen Cooling Systems in Power Generator

Hydrogen Cooling Systems in Power Generator

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

Innovations from General Electric

Innovations from General Electric

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.
