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.
Pressure Regulating Valve or commonly abbreviated to PRV is a component of hydraulic or pneumatic system that serves to adjust the fluid pressure of the high pressure system resources (such as pumps, compressors, or reservoir) to the low-pressure system. PRV is always in charge of maintaining fluid pressure value is lower than its supply pressure, therefore the pressure of the fluid before passing the PRV will always be greater than the pressure after passing through PRV. It can be said PRV serves to lower fluid pressure so that it meets system requirements specification, or also for the security and safety of use.
Broadly speaking there are two types of PRV when seen from operational systems, namely single stage and two-stage pressure regulator. The above picture illustrates a PRV system with only a single stage pressure regulator. The image appears on several major components such PRV inlet and outlet pressure gauge, diaphragm membrane, spring, poppet valve, as well as a lever to adjust the set point PRV working pressure. Pressure gauge serves as a good appointment fluid pressure value on the source side and the output side pressure of the PRV. Diaphragm function is to create a flexible working space in the PRV capable of changing volume. Two springs on the PRV system serves to generate pressure equilibrium, while Poppet valve serves to open and close the fluid flow.
The most fundamental difference of PRV with a two-stage pressure regulator as compared to the previous system is the two-stage system was used spring and diaphragm membrane that is more to create an equilibrium in the PRV chamber (chamber). At the time of the fluid pressure in the outlet room to fall, then spring 1 will suppress the diaphragm and poppet valve 1 so that a higher pressure fluid in the chamber will go into the outlet chamber. When the fluid pressure chamber drops because they have got into the room outlet, then the same process occurs in the spring 4 which will encourage the poppet valve 2 so that a higher pressure fluid went into the chamber. When the fluid pressure outlet is in conformity with the pressure set point was, the spring system will form an equilibrium so that both poppet valve will be fully closed.

SpaceX, a private company engaged in the assembly of the spacecraft is planning to send a spacecraft named Red Dragon to Mars in early 2018. The company owned by Elon Musk has said openly will carry out further Mars exploration involving humans and no longer using robots someday. Although it has been stated that the company did not specify how many spacecraft that will be sent to Mars associated with this mission.
The spacecraft will be flown in from SpaceX to Mars, using the booster rocket Falcon Heavy. Falcon Heavy rocket is a newer version than the previous version of the Falcon 9 rocket that will first be tested for a launch capsule heading to Mars with no humans involved in it. When launching the capsule with heavy payloads landed well on Mars, then SpaceX will launch involving humans in it. In addition, if SpaceX is able to do that, then SpaceX was the first private airlines were able to land a spacecraft on another planet. The aircraft also will be used as a residence by the astronauts who went to Mars. SpaceX company also said that the Red Dragon is a spacecraft weighing 6,000 kg before sliding out of the earth. Then when it is outside the Earth’s atmosphere, some parts like a rocket booster will be released from the main spacecraft. Then one by one the other parts that are not needed will be released until finally landing on Mars successfully done so only in the form of capsules. At the time of landing is successful, the capsule has a weight of 3000 kg.
The landing propulsion machinery is a machine that allows landings efficiently to deliver cargo in bulk to the surface of Mars. This is one way that NASA still does not know how to do it. If not using the engine driving the landing capsule is definitely potentially suffered severe damage. It is caused by a very different atmosphere between the Earth possessed with Mars. The atmosphere on Earth thicker, thus allowing the capsule to be crash landed more slowly. Mars has only a much thinner atmosphere than Earth, so that the capsule would have the potential to experience a violent collision with the surface of Mars. To prevent conflicts, the driving engine landings can be controlled very necessary. Read more
In the future all electronic equipment will be designed to be thinner and thinner. There are even some electronics to be designed to be more flexible. The researchers made that all possible. The researchers have managed to create a display that is named Organic Light Emitting Diode (OLED).This display is very thin, flexible, and has a protective layer, thus enabling creation of electronic skin (e-skin) to detect the blood oxygen level, heart rate sensors e-skin for athletes and other applications.
OLED invention is intended to integrate electronic devices with a human body to increase or restore the function of the body, so in other words to be used as a biomedical application. The integration of electronic devices with a human body it is becoming a trend researchers around the world.In particular, the electronics that can be used must be thin and flexible to minimize the impact where they attach to the body. However, most of the devices developed so far require millimeter thickness and made of materials such as glass or plastic substrate with limited flexibility. Meanwhile, usually organic devices with micrometer-scale thin flexible yet stable enough to survive in the open air.
This research could also be directed towards the manufacture of mobile phones too. The advent of mobile phones have changed the way we communicate.While this communication tool designed to get smaller and smaller over time. But sometimes that is not practical is that device shall we take to use it. Would not it be more practical to use the device at all times attached to the body and can even show emotion or level of stress or anxiety us. Besides not having to carry the device at all times, at some point it might be to improve the way we interact with the people around us.

Remember you will Hoverboard? Skateboard without wheels that floated above the ground? Or also Water Flyboard, other extreme sports. Not yet old extreme sport is booming, there are already competitors are even crazier. Introduce Flyboard Air, a new extreme sport which is currently still in the testing phase.
Air Flyboard if observed at a glance may work similar to Water Flyboard. But you need to know that Flyboard water use turbojet engine to produce lift that is great. If Water Flyboard very limited with the water suction hose length, then Flyboard Water may only be limited by one thing, the courage of the riders. Yes, the flying apparatus is claimed to be able to fly up to 10,000 feet or the equivalent of more than 3,000 meters!
The use of a jet engine makes Flyboard Air works similar to an airplane. Needed space for the fuel, combustion air, and that certainly is the stability of the rider. It appears also sport this new tool more widely used on the surface of the water, I suspect this was done because the hot air in the combustion engine Flyboard jet is definitely more secure if it is disposed on the surface of the water rather than on land.
