The Intel researched the intelligent home plug
According to foreign media reports, during the annual Intel "Research @ Intel day" activities, Intel R & D smart home plug, then be able to show the use of household appliances, power and energy to eliminate waste.
It is reported that over the years Intel "Research @ Intel day" activities to a variety of attractive design features, these ideas may never fully mature into products, but this year's event, Intel's R & D staff has to show a real is in the home products. This equipment, like plug can be inserted into any socket at home, and then the home network can provide the operation of each electrical comprehensive information.
Like Shazam, and Gracenote can identify any song like that, Intel's technology can change the electrical frequency and voltage spectrum derived from a unique signal to identify any kind of electrical appliances. Intel CTO Justin (Justin Rattner) said: "The staff told me that they believe they have developed this equipment can be shut or open when the appliance to identify the electrical model." Over time, according to the signal derived from spectral analysis changes, the device can tell the user "Do you want to bad electrical, and whether it becomes a need to replace the inefficient" and other information. With Intel's strength, the device to avoid information overload control panel and interface graphics and complex issues. The touch screen device can also be clearly and accurately in any electrical power, and the electrical power consumption rates and so on. Through this device, users can get on how to make energy efficient appliances information, but there is a clock on the touch screen to display the warning-shaped pattern are used in electrical appliances at home if the power is too high. In addition, this device will also be able to use different time and energy with the neighbor's own comparison of energy use, thereby encouraging energy conservation social network.

American newest research is expected to distill fuel from air by low cost
According to the ABC Web site on August 8, scientists said, the use of a common soil bacterium from the extract of the enzyme, can be transformed into thin air motor fuel. The method is expected to realize a low cost to produce environmentally friendly fuels carbon neutral, while the car engine without the need for substantial changes to the original design.
Living in food crops such as soybean roots in soil micro-organisms called Azotobacter would create an enzyme - vanadium nitrogenase in nature, an enzyme that generates ammonia by nitrogen. Now, the researchers confirmed that carbon monoxide can also produce propane, a camping gas stoves commonly used fuel.
The researchers found that when the oxygen and nitrogen vanadium nitrogenase from there, "away" and replaced with carbon monoxide, the vanadium nitrogenase will automatically start using the carbon monoxide to produce short-chain, the carbon chain length of only two or three atoms . Jonas Peters that the California Institute of Technology, vanadium nitrogenase of this new capability is a "far-reaching discovery", will have important industrial applications.
However, the real excitement is the potential for the manufacture of motor fuel. Co-author of research papers, University of California, Irvine scientists that this enzyme can eventually be modified so that it can not only create a simple chain of three carbon atoms of propane molecules, but also to produce the form of long-chain molecules of gasoline. He said: "Obviously, if we can create carbon - carbon long chain, which will produce synthetic liquid fuels is a new way."

New solar nanoscale robots can absorb oil effectively
According to foreign media reports, the Massachusetts Institute of Technology scientists have developed a group can effectively absorb the spill nanotechnology robot solar energy, these robots can be removed within one month, the Gulf of Mexico the size of the spill. And this development is not only concentrated in the built environment using sensors and the first hand-held electronic devices, but also indicates that this kind of nano-materials can absorb oil spills will be in the next four years would bring positive effects.
It is learned that long-solar nano-materials robot 16 feet (4.8 meters) wide and 7 feet (2.1 meters) and weighs 35 pounds (16 kg). The robot's "head" unit has two square solar panels, they can use solar power to drive the robot into the water slide freely. When the robot in the water "around the patrol", the robot body's absorption of nano-vortex machine will play the role of oil - whirlpool machine in a thin flexible belt will be chosen for the adsorption oil spill work.
Now widely used around the world not only the design style skimmer old (has not been updated for decades), and monthly maintenance should be entrusted to the shore several times. Compared to this old skimmer, solar nano-materials will make future oil robot to work faster, safer, more efficient, scientists have discovered through testing, each robot only needs 100 watts that can last for several weeks to , if the number 5000 to 10,000 units within the scope of the robot on the surface of the water non-stop work, less than a month removed from the Gulf of Mexico will be a big area of oil spills, each robot can be moved per hour take the number of gallons of oil. Therefore, nano-robots are expected to work in the future oil fields are common. This solar nano-materials robot current average price of ten thousand dollars to between twenty thousand dollars.

Scientists invented efficient solar cellsin in the low light condition
According to foreign media reports, scientists at Massachusetts Institute of Technology recently developed a reference leaf photosynthesis with the role of self-repair of solar cells. At the same time, the battery can be as light as the molecules they gathered closely together, resulting in twice the normal battery storage of electricity.
It is reported that photosynthesis can convert solar energy to electricity and then the electrical energy into chemical energy for the active, and ultimately be converted into stable chemical energy of the process that will generate electricity for the use of photosynthesis to provide the foundation. Since photosynthesis can be relatively efficiently convert solar energy into electrical energy, but also in the process of transformation consumes only water, not the slightest contamination of the environment, so in the increasing scarcity of other natural energy sources, environmental pollution is serious today, use photosynthesis to solve human demand for energy has become a hot topic of scientific research. The place is the chloroplast photosynthesis. Higher plant chloroplast diameter 4 ~ 10μm, the thickness of between 1 ~ 2μm. In the chloroplast, there are several to dozens of basic grains, each of the structure of grana stacking by cystic made the film in the cystic structure, with photosynthetic pigments. Photosynthesis consists of two main steps: first, the need of light involved, the cystic structure in the chloroplasts of light on the reaction; the second is no light involved, and enzyme in the chloroplast stroma in the dark reaction. Light reaction is divided into two steps: primary reaction, the conversion of light energy into electrical energy, the decomposition of water and release oxygen; electron transport and photosynthetic phosphorylation, active electrical energy into chemical energy. Dark reaction is based on the C5 compounds in plants (1,5 - bisphosphate ribulose) and CO2 as raw material, using light reaction of the active chemical energy, the formation of stored energy of glucose.
