Vertical Axis Wind Turbine and Using Solar Power

Vertical Axis Wind Turbine

There are two different types of wind turbine; Vertical and Horizontal. Each one performs their own function and they each of their advantages and their disadvantages. You should pick the one that is best for you and your needs. They do have one thing in common and that is that they produce energy from winds. They just do it in a different way. Vertical axis turbine has the main rotor shaft running vertically instead of horizontally. This direction can have its advantages and disadvantages. The advantage is the gearbox can be put in the bottom of the turbine, unlike the horizontal turbines. All the weight is not at the top of the tower.

It also does not need to be pointed in the direction of the wind. The disadvantages of vertical axis wind turbines is that there can be pulsating torques that can happen during each turn when the turbine is running in the same direction as the wind. They produce a smaller amount of energy from the wind.

Different Types of Vertical Axis Wind Turbines Windmill with a rotation sail. This type of turbine is the newest out there as it looks like sails on a ship once it is up and running. The sails can expand or contract to the changing winds. There is three sails on it and the speed is managed through magnetic counter that expands or contracts these vertical sails. It has a control unit that will help to control the sails so the damage will be minimal. The sails might tear but the frame is durable and will last through the storms.

Aerodynamic turbine is made up of airfoil base that is designed to capture the kinetic energy flowing from an artificial current to the center. It can utilize most of the air mass that passes through by redirecting it over the upper turbines. It can respond to wind and also rivers, creeks, oceans or other free flowing water systems.

Darrieus Wind Turbines are efficient but because of their size and shape they can produce cyclic stress on the tower which can wear it out sooner. It features three blades that work well in higher winds. They are held up by external structures that are connected from the ground up.

Giromill is a type of meal that features three vertical blades. It is self starting so the maintenance is low. These types of mills a low blade speed but they can create a high performance and success in channeling the energy from every turn of the blade.

Savonius Wind Turbine mills have two scoops that are used for wind conversion. Some do come in three scoops that make it self starting. They look like long helicopter blades that are bent in a direction. This style and shape is to provide enough energy to be adequate.

Windstar Turbines has straight aluminum blades that are attached on each end of the rotating shaft. This windmill features more than one rotor and they each have their own dual braking system that has pneumatic disc brakes. They are designed for strong powerful winds.

The advantages to running a vertical axis wind turbine is that they are easier to maintain and reduce cost, can withstand almost all wind, low high, smaller and easier to transport. The disadvantages are they take twice as much time to produce efficient energy from winds, need to be installed on flat land, low starting torque, some models use guyed wires which can add stress to the bottom. The design and the preference of the consumer make the best choice when it comes to choosing the right one for you.

Using Solar Power

When you think of solar power you think of heating and light for your home. That is one of the many things that we use solar power for. Solar power is everywhere and it is growing everyday. There are different products that are made using solar power. This article will list these products and their uses and also how solar power affects them. Solar power is using the sun’s natural heat to produce electricity, heat, and more. When you use solar power you are using the natural resources found that cannot harm the earth in ways that other methods can.

There are more products that use solar power than what we realize. A lot of the electronics made will use some type of solar power in order to function completely and accurately. For example, calculators are solar power products. These calculators may or may not have on and off switches. Some rely on the solar panel completely in order to stay or turn off. Solar power calculators need a certain amount of light inside the solar panel in order to turn the calculator on and perform what you want it to do; add, subtract, divide, multiply and more. The solar panel in a calculator is not as big as the one that you would to power your home. The size needed for a calculator is adjusted before installation to provide the right amount of what it needs. Solar power products can be found in travel products, outdoor recreation, safety products, emergency products and more.

Radios have are produced with a solar panel inside that transforms the sunlight into energy allowing you to listen to your radio while you are outside. You may also find solar power in flashlights, battery chargers, mobile phone chargers, watches, lanterns, emergency products such as sirens and lights. As you see there are several products that are using the solar power technology. Portable chargers are great to use because they charge the product that you have using the sunlight just as easy as turning a calculator on. Camping equipment and supplies work well with solar power because it allows the sunlight during the day to supply their lanterns, flashlights and radios at night.

Cooking outdoors can also be done by using solar power in order to heat the element that will ignite and allow for even cooking. Because more people are turning to solar power for their future energy source there are companies that are marketing products that are produced using solar power. Appliances are being made for solar power homes. These appliances, refrigerators, stoves, dishwashers, and more will work great in a home that is generated by solar power. They are built to conserve energy even more so than the products available to everyone.

In the future when everything turns to solar power in order to work we will be prepared using the knowledge and the products that are available today. We can’t predict the future in solar power but we can all do our best to make it happen.

Ways To Use Solar Power For Heat

We have become accustomed to turning a dial or pushing a button in order to have heat. These ways are nice but they may be inconvenient as well. Heating homes, schools or businesses with solar energy is not only easy but cost effective as well. There are several ways that we can capture the sun’s heat even in winter times. In order to capture the sun’s heat you need a solar source. This source can be something that will attract the sun rays but trap the heat from it when it enters the source. A good example is a sunroom.

These rooms are attached to a home or a building and are constructed of glass panels from the floor to the ceiling. It is usually facing the morning sun in order to get the full affect of the heat. When the sun shines into the room the glass allows the sunrays heat the furniture and everything in the room. These areas become the source that holds the heat in so that it will not escape back out of the glass. This type of heating is natural and can be very efficient if it is constructed correctly.

Other forms of solar power heat are:

Thermal mass that absorbs and holds in the heat. It traps and holds heat while the sun is shining and disperses the heat when the sun goes down.

Trombe Wall is a natural solar heating and ventilation system that uses air channels to hold the heat between a glass object and a thermal mass that is facing the sun. The sunlight gets trapped and stored inside this wall and is then circulated though vents and the top and the bottom of the wall. The wall radiates the heat.

Transpired collector is also a wall that is used facing the sun. The wall absorbs the sunlight and heats the air when it enters into the ventilation system.

Solar Cooling is a great way to ventilate a building. It absorbs the solar heat and cools it making ice with a solar powered steam engine that is attached to a cooling device.

Solar Chimney is also a solar ventilation system. It is made of a thermal mass that is hollow inside. The chimney will warm the air inside the chimney and causing the heat to rise. The rise allows the air to circulate and vent properly.

There are several ways that we can provide heating and cooling to our homes, businesses, buildings or other structures that need to be heated. The ways listed above are by using all natural material that will pay off in the long run when you have heat using the sun and not an artificial heating source that may be produced by non-renewable resources. We all need heat no matter what. We need to find out what ways we can save the heat from the day to keep our house warm at night. Not only does it work for heating but also cooling as well.

Unique, Bra Detect 'True Love'

Finding true love is certainly not easy. But in fact the presence of technology is now able to help the weaker sex to find true love right and according to his dream, for example by using the help of a sophisticated bra.
This bra can function as a selection tool while securing its true love of various acts of harassment. Sensors mounted on the advanced bra can detect its heartbeat.

The data captured by the sensor in the form of its heart rate was then sent to a special application installed on the phone. Well, the application is in charge of analyzing the heart rate that beats in the chest of women who wear them.

And incredibly, when you find someone that feels 'right' heart rate will automatically have a different rate. When it reaches a predetermined threshold bra hooks will then detached by itself.

As reported by Rocket News, bra tester true love is claimed as the world's first underwear scientifically engineered to women so that they can actually read the signals in the body.

Bra sophisticated detection of true love is the result of development of a Japanese company, Ravijour. The slogan 'We will do whatever it takes for the needs of women' that have made this company does not expect the fair sex wrong step in choosing a partner.

Warming Up: Alternative Energy Source And Global Warming

Global warming is one of the “hottest” issues nowadays. The current climate change is the worst yet to happen. Global warming is an overall increase in world temperature which is attributed to the increasing number of greenhouse gases trapped in the atmosphere. Searching an alternative energy source is considered a way of reducing the toxic emissions.

Greenhouse gases can be produced both by natural and industrial processes. The most abundant greenhouse gases on earth’s atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, ozone and CFCs.

There are several sources of greenhouse gases. Burning of fossil fuels and deforestation lead to higher concentration of carbon dioxide in our atmosphere. Without the trees and plants to take in the carbon dioxide emitted by burning fossil fuels, natural gas and petroleum products, all of the CO2 emitted stays in the atmosphere.

Also the use of CFCs or chlorofluorocarbons in refrigeration systems and in fire suppression systems and other manufacturing processes also increase the greenhouse content of our atmosphere. While the use of non-organic fertilizers in agriculture also lead to higher nitrous oxide concentrations, another greenhouse gas.

In the United States, greenhouse gas emissions mainly come from the use of fossil fuels as energy source. Approximately 82 percent of the greenhouse gas emission in the United States in 2006 came from the combustion of coal, natural gas and petroleum (United States Energy Information Administration). Meanwhile in Asia, Chine is expected to increase its emission of greenhouse gas because of the construction of old-fashioned power plants in its internal provinces. Currently, the carbon dioxide concentrations in the atmosphere are the highest in 150,000 years. The 1990s was most likely the warmest decade in history, while 1998 was the warmest year (Greenpeace).

Not controlling the greenhouse gas being emitted by human activity can increase climate change the next hundred years that will be much faster than anything known and recorded in history. There are necessary steps to be undertaken to control the toxic emission that will soon be killing us.

To minimize the consumption of oil, petroleum and other fossil fuel, we should use energy efficiently. Energy that we use should be generated from renewable energy source, which would mean harnessing the natural energy from the sun, winds, crops, tides and waves.

Green energy is another term used to describe sources of energy that are considered to be environmentally friendly, which is also similar to the renewable sources of energy.

There are numerous ways of generating electricity and energy from renewable and natural sources that generate clean and safe energy. Wind, sun, and heat can generate electricity for less price and less carbon emission than those of coal and even gas.

Shifting the world’s attention to alternative fuel source other than relying on fossil fuel is among the solutions in resolving the drastic climate change. Greenpeace cited that with renewable energy and using it smartly, can deliver half of the world’s energy needs by 2050. Greenpeace also cited that it is feasible to reduce carbon dioxide emission to almost 50 percent within the next 43 years.

Governments are taking steps to use and tap alternative energy sources as main source of energy. The European Union leaders made an agreement in March 2007 to ensure that 20 percent of their nation’s energy should come from renewable fuels by 2020. This is part of their effort to cut carbon dioxide emissions and other greenhouse gas. There are even governments offering incentives to their residents who are using green energy.

Alternative energy source may not be the only way to reduce the greenhouse emission that human activity produce. There are simple ways in which we can do to contribute in reducing toxic gas emission and mitigate global warming.

What Are The Advantages And Disadvantages Of Using Green Energy Sources?

Today, we are now aware of the effects of global warming. Fortunately, it’s not too late and we can still change which is why many are pushing for green energy sources.

The advantage of using green energy sources is that it is clean so it does not emit anything harmful into the air which has an impact on the environment. It is also renewable which means we will never run out of it unlike oil which is expected to dry up in a decade or so.

Although green energy facilities are expensive to build, it requires less maintenance so you don’t have to shell out a lot of money to operate it.

It can also bring economic benefits to certain areas even boost tourism.

While these sound good, there are some who say that there are advantages to using such technology.

While green energy sources can produce electricity, how much it can generate is not consistent. This is because we have no control of the weather so if a certain area relies on solar energy and there is a weather disturbance, it will not be able to convert sunlight into electricity.

Building these facilities also requires a lot of land so we may have to cut on farmland which is what many are concerned about if more wind turbines are to be put up.

Another disadvantage is the fact that some of the green energy sources cannot be installed in certain areas of the planet. For instance, wave energy can only be utilized if the waves coming from the ocean reach at least 16 feet. The use geothermal energy can only be done in geologically unstable parts of the planet.

But if you look at such arguments, places that cannot use one form of green energy source can be substituted for another. If wind turbines need more space, they can be installed near the coast instead of putting these on land. A study shows that you can generate more electricity while these are in the ocean.

While the weather is something we cannot control, it is not everyday that there is a weather disturbance so this too shall pass. If solar energy is being used and the sun is covered, the emergency generators will be activated and use up the energy that was stored.

The point is that there are ways around the arguments put by certain individuals which discourage the use of green energy sources. In fact, research is ongoing to try and harness other means to generate the power we need.

A very good example of this is called ocean thermal energy. Power is generated by harnessing the different temperatures in the water. It is currently being used on a small scale both in Japan and Hawaii.

In the US, only 7% of green energy sources are used nationally. This was much higher 11 years ago and if we don’t have to worry about the cost of oil or even reduce our dependency on it, we have to invest more in this clean energy.

We can get it from green energy sources such as biomass, biodiesel, geothermal, solar, water and the wind. These are things we have all around us and all it takes is for someone to harness it instead of relying on traditional non-renewable means to produce energy.

What Is Solar Energy?

In order to know where to find solar energy you must first know what solar energy is. Solar energy is energy from the sun. When the sun is shining solar energy is being produced as it sends the heat radiating to the earth. You can find solar energy anywhere or anything that the sun can shine on. There is a way that you can save the sunlight in order to provide heat during the cold, which is what millions of people have done throughout the years. It started thousands of years ago when people where able to use a thick lens or magnifying glass on an object that would attract the sun rays on that particular object and could get so hot it would catch fire. This gave a new prospective on how strong the heat from the sun really was.

The problem with capturing the suns heat is the fact that when it reaches the earths surface it does not go to one particular spot. It is spread evenly over the earth where the sunlight is able to reach. When this happens you may find it difficult to heat something using only the sunlight. Although the area or object may be hot if left in the sun too long it will not reach the full heating potential of the sun’s light.

In order to use the heat efficiently to heat a room after the sun goes down or when the sun is unable to shine because of clouds you will need to use a source that will attract the heat to one particular area. This source is called a solar collector. The solar collector attracts a lot of sunlight to one particular area allowing the sun to pass through the source and into the space. The objects in the space absorb and hold the heat from the sunlight and trapping it so it will not get back out with the help of the source. Glass is a great solar collector because it allows the sun to pass through it and into the space but the heat from the sun can rarely escape leaving the space under the glass to become warm or hot from the heat. The objects in the space help to hold the heat as it comes in so that the space will stay warmer longer. This allows the area to be heated using solar power.

Because glass is a natural solar collector it makes it great to put into a greenhouse or a sun room. The glass attracts the sunlight and traps the heat inside so that they temperature in the greenhouse or sun room remain warm even at night when the temperature outside may be cold.

Solar energy can be found anywhere the sun shines but in order to fill the heat you must have direct sunlight for an extended period of time. If you just use the morning sun to heat your home your house may not stay warm through the night.

Hackers Attack the Israeli Ministry of Defense

Hackers just hacked into computers belonging to the Israeli Defense Ministry. Remarkably, the action is done only through an email attachment containing malware.

As reported by The Hacker News ( 27/1 ), the malware is XtremeRat which is spread through email support . This malware e-mail accounts Secret Shin Bet Security Service of Israel and then quickly spread.

Noted, there are 15 computers DoD Israel who became victims. In fact, malware is also capable of spreading to computers during the Civil Administration is monitoring the Palestinians who live in Israel.

Civil Administration itself has been used to control the traffic of goods between Israel and the Gaza Strip. It is not known whether this malware is specifically intended to destroy the system.

Meanwhile, there is also alleged that the attack was intended to destabilize the Palestinian work permits in Israel. It may be that it is the motivation behind this attack.

The attack itself causes the computer 15 controlled hackers for several days since 15 January last. Unfortunately, the Israelis did not want to announce more about this attack.

"We will not comment," a spokesman for Israel's Civil Administration, Guy Inbar.

Big Asteroid, Apophis Hit Earth in 2036

Space does not only consist of our earth alone. The number of planets and galaxies shows us how big the universe is. Quite often between one component with the other components of the space experience one symptom that could lead to a collision large explosion.

The Russian government has confirmed that it was formulating big plans to prevent a large asteroid known as Apophis from colliding with the Earth in the coming year 2036.

"A scientist recently said something interesting about the course of an asteroid approaching Earth constantly," Roscosmos head Anatoly Perminov explained in a statement cited by RIA Novosti.

"He has calculated that the asteroid will surely collide with Earth in the 2030s."

However, Perminov stressed that the Kremlin is not planning a nuclear strike against the dangerous asteroids.

"There will be no nuclear explosions later, everything will be done based on the laws of physics."

He added that Russia could eventually invite astronomers from the U.S., Europe and China to participate in the new project begins.

"People's lives will be at stake. We should pay several hundred million dollars and design a system that will prevent a collision, rather than sit and wait for it to happen and kill hundreds of thousands of lives."

However, it should be noted that the forecast was terrible Perminov seems to contradict the statement recently published by NASA underestimate the possibility of a collision between Earth and Apophis.

Hopefully this plan was so successful that the Russian government money spent will actually be useful later to save human life in our beloved earth.

South Korea Set fastest internet in the world

Latest time, The British telecommunications company to test the very high- speed broadband, 1.4 Tbps. However, such testing is still a experimental alias can not be enjoyed by consumers in the near future.
Unlike the case with the implementation plan 5G networks in South Korea. As reported by Phone Arena, Ginseng that is preparing the implementation of the 5G wireless network speed 1,000 times faster than the latest 4G technology.

The exact figure is about 10 gigabits per second, or Gbps ( 1 Gbps is equal to 1,000 megabits per second ). With such a high speed, a full -sized 800 MB movie is said to be downloaded in less than 1 second. For comparison, the 4G network takes 40 seconds to download the same file.

Ministry of Science and Technology of South Korea set aside $ 1.5 billion to create a network called the fastest internet in the world. The plan, 5G network will be implemented in 2017 and fully completed in 2020 for commercial purposes.

" We help the growth of 2G services nationwide through the 1990s, the 3G in the 2000s, and 4G sometime in 2010. Now is the time to go further by 5G, " the Ministry of Science and Technology of South Korea in a statement.

The electronics giant and mobile operators in the country, such as Samsung, LG, SK Telecom and Korea Telecom, are expected to invest in the program 5G network.

South Korea itself is known as one of the countries with the best internet connection in the world. This country is constantly at the top of the fastest internet speed matters.

What Is Alternative Energy?

There is a lot of energy that we can harness if we only seek to research and develop the technologies needed to do so. We can get away from the fossil fuels and the old electrical grids by turning to alternatives to these energy sources.

One of these alternative energy resources is wind power. Wind turbines continue to be developed that are progressively more energy efficient and less costly. “Wind farms” have been springing up in many nations, and they have even become more strategically placed over time so that they are not jeopardizing birds as former wind turbines did.

Another alternative energy resource is the one that is most well known: solar energy. This involves the manufacturing of solar cells which gather and focus the energy given off directly by the sun, and translate it into electricity or, in some cases, hot water. As with wind energy, solar energy creates absolutely zero pollution.

Ocean wave energy is seen by governments and investors as having enormous energy generating potential. A generator in France has been in operation for many years now and is considered to be a great success, and the Irish and Scots are running experimental facilities.

Hydroelectric power has been with us for a while and where it is set up, it is a powerful generator of electricity and cleaner than a grid. However, there are certain limitations to the availability of the right places to set up a large dam. Many run-of-the-river, or small and localized, hydroelectric generators have been set up in recent times due to this limitation.

Geothermal energy is extremely abundant, since it lies directly beneath our feet, just a few miles below the earth’s surface. This energy is produced by the heating of water through the actions of earth’s fantastically hot molten core. The water turns to steam, which can be harnessed and used to drive turbine engines which in turn generate electricity. Great amounts of research and development should be put into geothermal energy tapping.

Waste gas energies, which are essentially methane, reverse the usual energy-pollution relationship by creating energy from waste that lies in the dumps and from some air pollutants. This gas is used in fuel cells and can be used in standard gasoline generators.

Ethanol is a gasoline substitute and is created from such things as wheat, sugarcane, grapes, strawberries, corn, and even wood chips and wood cellulose. There is controversy over this fuel with regards to its ever becoming truly economical or practical except in very localized areas, but technologies for its extraction and admixturing are continuously being refined.

Biodiesel energy is created out of the oils contained in plants. So far, the commercial stores of biodiesel have been created using soybean, rapeseed, and sunflower oils. At the time of this writing, biodiesel is typically produced by entrepreneurial minded individuals or those who want to experiment with alternative energy, but commercial interest from companies is on the rise. It burns much cleaner than oil-based diesel.

Atomic energy is created in atomic energy plants using the process of nuclear fission. This energy is extremely efficient and can generate huge amounts of power. There is concern from some people about what to do with the relatively small amount of waste product atomic energy gives off, since it is radioactive and takes hundreds of years to decay into harmlessness.

Underwater City of the Future

When submerged lands on earth, when the human civilization thrown into the period when Kevin Costner explore the world on a boat full of water ( Waterworld, 1995). What can humans do ?

London architect may answer some of these concerns by designing a building that became a city under the sea to anticipate if the earth submerged in sea water in the future.

Building, or city is named after the Sub - Biosphere 2 is claimed to be able to accommodate up to 100 people in a dome. In each dome has been designed so that the production of food, air, biosphere, laboratory, complete available. In short, measuring 1,105 feet in the dome 's human require other needs of the outside world.

Pauley designed this building because he believes the earth will be drowned by sea water in the future . He said that, if global warming is not addressed and kept walking, ice will melt and make the earth drowned by sea water.

"I like when people realize that and want to have a house under the sea, I already have it," Pauley said as quoted by the Daily Mail.

Why Is Hydropower A Green Energy Source?

Why is hydropower a green energy source? It is because we are able to harness electrical power by converting water into electricity.

The use of hydroelectric power or even hydroelectricity dates back to Ancient Greece and China when they installed waterwheels in rapidly flowing rivers to turn millstones and other equipment. Years later, this was used in the New World which is now known as North America to power saws and other equipment.

But the hydroelectric plants of today still use the same basic principles as the historical waterwheel with some variations. The difference is that we use the force of the power to push the turbine which in turn powers a generator thus generating electricity.

To make sure that there is a steady flow of power being produced, a dam has to be built to retain the water. If there is a need for more power, the gates of the dam are opened so water can be released. During non-peak, the gates are closed. To ensure there is water at all times, some dams have a recovery and pumping systems to the water released can be used again.

There are issues with the use of hydroelectricity. Some claim that it poses a problem for fish and aquatic plants on both sides of the dam. Because the flow of water has been altered, the nutrient rich silt which helps crops grow could be affected which is exactly what happened when the Aswan Dam was completed in Egypt.

But there are ways to fix that and the bigger picture is that power produced from hydroelectric plants do not generate any emissions or waste which happens to be much better than operating a coal-fired power plant.

There is another way to generate hydropower and you get this form the sea. This is also known as wave power or wave energy which uses changes in the air levels of sealed chambers to power turbines. When a wave rises into the chamber, the rise water pushes the air out which then turns a generator.

Once the wave goes down, air flows into the turbine and back into the chamber through doors that will close.

These chambers remain afloat on the ocean and how much power it produces varies. A lot of these are used on the western coasts of Scotland, northern Canada, southern Africa, Australia, and the northwestern coasts of the United States. These systems are usually small and can power a warning buoy or a small light house.

There is also tidal energy. The difference with wave energy is that when the tide approaches, the water is trapped in reservoirs behind dams. When the tide drops, the water behind the dam is released thus producing power similar to a hydroelectric power plant.

This can only work if you have tides that are at least 16 feet and since there are only a few places in the planet that can do that.

Lastly, you have ocean thermal energy. Here, you get power based on the different temperatures in the water. For this to work, you need at least 38 degrees Fahrenheit difference between the warmer surface water and the colder deep ocean water. Still in the trial stage, it is used Japan and Hawaii.

Hydropower is a green energy source. It is safe to use and what is even better is that it is renewable.

DNA storage 2.2 million GB of data per Gram

One gram of DNA can store files of up to 2.2 million gigabits of data ranging from 468 thousand information or DVD, which can last up to more than six hundred years without rewriting.

Many molecular biologists were talking about DNA storage technology. And this technology is still foreign to us, but if we do not actually understand how the storage capacity of the human body.

Just imagine, since we are born continuously recording and learn everything. Where it all stored ? Decades of us live in the world still continues to record, and it requires considerable storage space, much larger than current technology.

Researchers from the UK have encodes DNA and translate the genetic material to reconstruct the written information, either sound or visual. In the past year, researchers and bioengineers Sriram Kosuri George Church of Harvard Medical School stated that they had kept a copy of one of the books stored in the DNA of the Church, with a density of about 700 terabits per gram, more than six times more dense than the data storage on the hard computer disk.

Current research led molecular biologists, including Nick Goldman and Ewan Birney of the European Bioinformatics Institute ( EBI ) in Hinxton - centered English, they study released in the journal Nature , stating that they have increased the DNA coding schemes to improve the storage density of up to 2 , 2 petabytes per gram, three times that of the previous findings.

The first team was first to translate written words or other data into the standard binary code (0s and 1s) and then convert them into trinary code. The next step rewrite the data into a string of DNA chemistry, such as Gs, Cs, and Ts. Storage density of one gram of DNA reached 2.2 million gigabits of data information, or about 468 thousand DVDs. The researchers also adds error correction scheme, several times doing the encoding of information, to ensure that it can be read back with 100 percent accuracy rate.

The explanation above is the same as is done in our bodies every second without stopping continued to write, and can be read back. In addition to demonstrating the ability of the storage of information in DNA, Goldman, Birney, and colleagues also reviewed viable when these technologies are used. While the Large Hadron Collider, have produced 15 petabytes of data each year , so the need for a large archive storage is growing rapidly.

Currently business institutions and institutional data archive store their data on magnetic tape, and to keep the data safe for decades require periodic rewriting (certainly no additional maintenance cost).

While DNA can be very stable for thousands of years if stored in a cool, dry place. The cost of DNA synthesis in accordance with writing code and decode can be resolved quickly, so allowing the data to be archived within 600 years or more.

But the cost of DNA synthesis became the most expensive parts up to 100 times, and probably would have declined by about 50 years. Cost is not a barrier, when data is written into the DNA of the users can not change or rewrite, not as data storage technologies available today.

Users can not access any particular piece of information, but must follow the order of writing that has been archived in the DNA. For example, the data writing 1,2,3,4 and 5, the user must read the order and could not jump over one of them.

From the explanation above, it could be someone who has the ability to 'read' your mind just by touching the hand, for example, actually he just read the records we've saved since birth.

New mission Chang'e - 3 Probe.

The Chang'e - 3 lunar probe has begun a long -term scientific missions and will have a durability test when continuously surveying the lunar surface, the source of the Beijing Aerospace Control Center.

For the first time China's lunar probes will operate for one year.
"We have made all the hardware and software ready for the tasks of long-term control and have developed new methods of management," said Cui.
JUNQI Liu, one of the chief engineer on the team Cui, said that during the year the task team will coordinate the Main control station to monitor the Chang'e - 3 lander and rover Yutu, and to organize scientific missions on the lunar surface.

One of the difficulties the team is to put the lander and rover to the moon sleep mode when the night comes and "wake them up" after the night was over, he said.
One evening in the month about 14 Earth days, the temperature drops below minus 180 C and no sun to provide electricity in solar panels instrument'.

He said the long-term management, lander and rover does not need many people to take care of it, because it's a team Cui, who has less than 20 people, capable of taking over from the Main control group.

"Furthermore, the small team will control the probe to perform scientific operations that can last several months. They will test whether the lander and rover to function properly in the long term and until the designed lifetime," added the officer." For the full year period, controlling approximately 15 teams will work day and night shifts, so this is really a tough job."

The lunar rover Yutu has a designed life time of three months, and the lander is expected to work for one year.

Yutu completed the first sampling of lunar soil using a mechanical arm on Tuesday, said the center of Beijing.

"Accuracy control mechanical arm at a distance of 380,000 kilometers has been realized in the probe, marking China's breakthrough in controlling a mechanical arm with high precision on the surface of the moon, "said Wu Fenglei from the center.

Yutu will continue to survey the lunar surface geological structure and search for natural resources, while the lander would explore the surface location to the end of its lifetime.

When "Adam" was on Earth ?

Researcher University of Sheffield, Dr. Eran Elhaik, and the University of Houston, Dr. Dan Graur, claiming the male ancestors of modern man, known as Adam, had lived 9,000 years earlier than scientists previously estimated.

Elhaik adding he and his colleagues to make sure Adam has appeared earlier than expected.

"We can say with certainty that some modern humans appeared in Africa at least 200,000 more than last year," he added.

According to two British researchers, as reported by Dailymail, Friday, January 24, 2014, Adam has lived in mainland Africa 209 000 years ago. The results of this study conflict with previous studies.

To determine the age of "Adam," the two researchers used genetic data that already exist today, such as calculating the Y chromosome, the male gene. Researchers calculated by multiplying the age of the Y chromosome genetic data on the average age of fathers who had their first child by the number of mutations found in research.

Researchers then dividing that figure by the Y chromosome mutation rate This is to find out how the average year is needed to determine the appearance of mutations. Indeed, this mechanism has the potential to manipulate recognized genetic variables. However, both studies show they actually present manipulations in previous studies.

"In our paper, previous studies manipulate all the variables for age precedes Y chromosome," said Elhaik.

Not Single

Elhaik also argue that modern humans interbred with hominin (human relatives who are closer to chimpanzees) that lived more than 500,000 years ago.

"It is also clear that no single Adam and Eve, but that there is a group of Adam and Eve who lived side by side and wander together on Earth," he said.

Previous studies University of Arizona, claiming the human Y chromosome is derived from a different species by mating twice that age older than Adam. According Elhaik, University of Arizona study indisputable.

China, Up From Sleep

China has built up thousands of new and high-tech development zones. In the 53 state-level new and high-tech development zones, a great many sci-tech research results have been put into use in production. By 2004, there had been over 30,000 high-tech enterprises in these zones, 20 of which had annual production values over 10 billion yuan, more than 200 over five billion yuan, and 3,000 over 100 million yuan. In these zones, the average growth in major economic indicators has been maintained at 60 percent per annum for 12 years running, and they have become important engines of national economic growth.

Beijing Zhongguancun Science and Technology Park

Private science and technology enterprises have also made great headway, some becoming group corporations with annual output values of anything from several hundred million up to several billion yuan. Their high-tech products now account for over half of the domestic market for such products.
Establishing export bases for new and high-tech products in selected high-tech industrial development zones is an important part of the government's plan for developing trade through science and technology. The first designated export bases, selected because of their rapid overall development, rich talent, excellent equipment, and rapidly growing exports of high-tech products, include the Beijing Zhongguancun Science and Technology Park and high-tech industrial development zones in Tianjin, Shanghai, Heilongjiang, Jiangsu, Anhui, Shandong, Hubei, Guangdong, Shaanxi, Dalian, Xiamen, Qingdao and Shenzhen. The Pearl River Delta, Yangtze River Delta and the Beijing-Tianjin region have the greatest concentration of such export bases, consequently export volumes of new and high-tech products from these areas account for over 80 percent of the national total.

What You Need To Know About Solar Power?

Solar power is everywhere because it comes from the sun. Solar power can be used to power electricity, pump water, to heat your home or office and power vehicles. With all that we can do with solar power you have to wonder why we don’t do enough to conserve the solar power. We could use it for almost anything and it would cost a fraction of what we are paying now. You can make a difference by doing your part is making solar power something you can use.

In order to power energy with solar power you need to know the basics of solar power and how it works. It takes a long time for heat from the sunlight to reach the earth. Unless it is concentrated into a particular area the heat from the sun will be distributed evenly over the earth’s surface where the sun is shining. When you want to use the natural sun light to power your electricity, heat or water you need to know the process to it.

You need to direct the sunlight to a concentrated area in order to have enough energy to power your source. Some of the biggest solar power towers are set up around the world. Solar power is not something that a few people are trying but solar power is about the future, everyone’s future. When you use a light in your home you may not realize the process that brings that energy to that switch so when you flip it on you will have lights. The energy that it takes to run power to our homes are not a natural way of energy. Conserving the energy that comes from the sun is the most natural way to equip our homes with energy, heat and more. When we use natural resources we save in several ways; by preserving the earth, cutting down on monthly and over all costs, and no inconvenient power outages.

Preserving the earth helps when you use natural resources that don’t hurt the earths atmosphere and everything in it. If we continue to use the power that we use today we may pollute the atmosphere so much that the right amount of sun will not be able to make it down to the earth’s surface in the future. Then we will have no other choice but to rely on our man made abilities to produce something that will cost us more than what it already does now. Pollutants will also harm life on earth as it starts to close in and start to harm us. Cutting down on monthly and over all costs can save you a lot of money in the future. In the beginning you may pay a minimal amount to be solar power efficient by purchasing a solar source. You can buy indoor and outdoor lighting, solar power windows and insulated doors in order to make your home more solar efficient. After that initial expense you don’t have the expense of paying a monthly bill to keep your service on. This also promotes others to use solar power to be more efficient.

When a storm blows through we are sometimes left without power for at least a day but sometimes more. When this happens we are so use to our conveniences that we have a hard time adjusting to going back to the basics when we are use to flipping on a light switch, using the microwave, taking a shower or bath assuming that the water can be pumped and heated the same as it always is. Loading the dishwasher or washing the dishes, washing and drying clothes. All of these services require the power to be on and when it is off is when you miss the services. When you use solar power you are less likely to experience these down times because your power is generated by natural energy.

Japan Hygiene Care Space

Space junk

Maybe you already know that in space are now widely garbage floating without direction. Most of the garbage comes from debris from previous space missions.

Along with the state, recently known Japan wants to make changes to clean up the rubbish strewn there . Through JAXA ( Japan Aerospace Exploration Agency ), it would make the waste disappear armed with magnets.

In collaboration with Kagawa University, JAXA will make satellite devices that have wires along 300Meter and contain magnetic field. So that the waste of space that would be interested in and stick.

Furthermore, they want to develop the larger, with the media along 1km and has a 30cm width of the magnetic material. That way, there will be more garbage stuck. The next step, the waste will be released in atsmosphere earth, so hopefully it will burn.

But this is still in the planning alone. So when the realization ? Japan said that it will begin in the coming 2019. .

Green Technology, Smart Face the Global Warming Solutions

Green Technology - Warm greetings dear reader wherever you are , how are you today ? Hopefully healthy and keep spirit run your daily activities . In this article , I want to talk about one of the global problems associated with the environment that is currently emerging discussed , which is about global warming or global warming. I am sure the reader already knows what it is global warming , at least never heard the word ' global warming ' or ' global warming ' when reading the news , watching television or listening to the radio . On average the news is persuasive or invite us to be aware of the surrounding environment . Even some no shows , events , competitions or other mat - mat campaign which aims to save the earth with the jargon of " Save Our Earth " .
My knowledge and readers about global warming is certainly different . To equate our perception of global warming or global warming , we should first discuss what is global warming , causes Expected global warming and the impact caused by global warming .

Global warming or often referred to as a process of global warming is increasing the average temperature of the atmosphere , ocean and land earth . How does the process of global warming ?

Process of Global Warming Process of Global Warming
Heat source in the heat of the earth comes from the sun that enter the earth . There are about 343 Watts per m2 hot sun toward the earth every day , but not all absorbed by the earth due to the sun's heat must pass through layers of air that is in the earth . When it passes through layers of air that is in the earth , there is a hot sun that bounces back into the atmosphere and there were landed to earth . Thus the heat absorbed by the earth is reduced , which is about 168 Watts per m2 .

After landing on earth , the sun will be issued again by the earth into the atmosphere . Normally , when the heat is released again by the earth to the atmosphere , the heat can be perfectly free , but now the heat is hard to get out of the earth ( trapped ) due to increasing greenhouse gases which are then referred to the greenhouse effect . Called greenhouse gases , because of the presence of this gas in the air can give the same effect as a greenhouse , which absorb and retain heat in it so that the temperature around it gets hot .

Shown in the picture , some of the heat get out of the earth and partially trapped in the earth . This is what causes global warming . That trapped heat causes the temperature of the earth is getting warmer .

Intergovernmental Panel on Climate Change ( IPCC ) or the " Intergovernmental Panel on Climate Change " is a scientific researcher group consisting of scientists around the world , noting that the global average temperature at the Earth 's surface has risen 0.74 ° C ± 0:18 ( 1:33 ± 0:32 ° F ) over the last hundred years .

The IPCC concluded that , " Most of the increase in global average temperatures since the mid 20th century most likely caused by increased concentrations of greenhouse gases due to human activities " . For more details about the greenhouse effect , readers can see the illustration below the greenhouse effect .

Greenhouse Effect Greenhouse Effect ( Image Credited : Rainbow )
The greenhouse effect is caused by the increase in the level of concentration of carbon dioxide ( CO2 ) , methane ( CH4 ) , nitrous oxide ( N2O ) and other gases in the atmosphere . The trigger of a variety of things , ranging from motor vehicle fumes , factory smoke fuels , forest fires , the use of chemical fertilizers , animal waste and other .

Actually , if there was no increase of these triggers , nature is able to properly absorb these gases to maintain the environmental balance . For example, carbon dioxide ( CO2 ), which accounts for quite a lot of greenhouse gases , should be absorbed by the plants need CO2 as photosynthesis material . However , the growth of the plants that were increasingly concerned with the amount of logging , while smoke from vehicles and factories continue to increase , making the greenhouse gases that surrounds the earth continued global warming will be difficult to avoid.

Causes of the Greenhouse Effect Greenhouse Effect Cause
If we already know what causes the greenhouse effect , it helps us to immediately prevent the buildup of greenhouse gases by the earth better . Currently , the readers may notice an increase in air temperature or excessive heat compared to previous years . It is one of the effects of global warming , which climate change .

Not only in Indonesia , even people in the world feel the same way . In addition , extreme weather changes quite well , such as a shift or a long span of time the dry season seem longer . Should have entered the rainy season , but why rain never fell ? Of all readers feel it , but not only as a result of climate change caused by global warming . There are many other consequences arising from global warming , let us consider one by one .
