May 23, a Finnish power company recently developed a new type of solar battery panels, use 3-layer nano-coating can efficiently absorb solar battery energy.

Finland Savory Solar Inc. press release said that this new type of solar battery panels there are two main technical innovation, first used a total of 3 100 nm thick layer of coating, because of reflected sunlight to reduce energy loss caused; The second is to use a “current technology”, let the water rather than directly in the heat-absorbing plate absorber plate connected with the pipe loop, thereby enhancing the energy conversion efficiency.

Savory solar energy company said performance in the tests, this new type of solar battery panels in the high temperature of 300 degrees Celsius to work, and the current requirements of solar energy products are generally only resistant to high temperature of 220 degrees Celsius.

The statement said that the next step in this enterprise R & D goal is to work these new products, increase the temperature to 550 degrees Celsius. The company also plans to Munich, Germany in June this year, the International Solar Energy Exhibition to display the products, and formally put into operation at the end of the year.

To build a large-scale solar power plants, need to occupy a lot of land. However, with the growing world population, fewer people and more conflicts more and more prominent. Neighborhood residents in order to reduce the occupation of land, construction of solar power plant is now a lot of remote areas in the wild, and the high cost of long distance power transmission. In order to solve the energy transport and land use conflicts, the French and Israeli researchers have developed a solar water system, is expected to build solar power plants in populated areas.

A few years ago, people considered the siting of solar power batteries plants, the choice is the desert, because the desert land is not worth much, but sunny. In fact, the sea conditions and more similar to the desert, it will not occupy the land, but not the surrounding buildings, mountains and other objects blocking the sun. The reason why people do not take into account before construction of solar power plants in the sea, because the traditional solar panels can not resist seawater corrosion. However, the French and Israeli researchers developed a resistance to corrosion of water floating solar power systems, solar power plants built in the sea has become a bright future together.

From the current perspective of the development electric world, mostly located in economically developed areas in coastal cities, the population of these areas is also very intensive. In these areas to build large-scale solar power plants, and residents will inevitably compete for precious land resources. However, the vast coastal areas near the mainland no one living on the sea, if the solar power plant built in the sea, and residents will compete for both land and does not require long-distance power transmission from remote areas, power, low cost, less waste of energy .

Water not only the construction of solar battery generation system on the ocean, you can also build in fresh water lakes, the best option is to reservoirs. Often a reservoir in the population centers, not just the role of reservoir water for the residents, but also for residents of hydroelectric power. The researchers can take advantage of proposed reservoir of resources for building solar power plants in the reservoir, the solar electric power plants and hydro power plants and transmission networks, can take full advantage of existing resources and reduce transmission costs, providing people with more adequate energy.

If a man loudly called the future because he has no idea is not likely that he is charging for their phones. Because scientists are now developing for the mobile phone battery charging by voice technology, the greater the charge the faster the sound.

Recently, South Korean scientists have invented a device that can make phone calls using sound when charging. The technology can be the sound into electricity. This means that those who like to “talk on the phone”and not only do not need to worry about mobile phone users will soon be out of battery, but also for the cell phone batteries keep charging, louder, faster charging. It is reported that this technology is not limited to mobile phones can also be integrated into the portable player field.
 Sungkyunkwan University researcher Sang-Woo Kim says, as the speaker sound will be converted to electrical signals as sound signals can be power, this process is reversible. He added: “Many people are exploring how to capture energy from the environment, our daily lives and the surrounding area is full of a lot of sound, but no one will see it as a source of energy, in fact, speech, music or Is the noise can be converted to electrical energy to use. “This device is the use of piezoelectric effect to generate electricity, the volume of about 100 decibels can convert the voltage of 50 mV. But the general mobile phone operating voltage of 2 to 3 volts, and the people’s daily volume of 70 decibels to speak, so far theb battery technology can not charge for normal phone calls.

Recently, the Canadian investment dealers BMO Capital Markets analyst Keith Bachman is expected, iPhone 5 will debut in September, it will be evolutionary rather than revolutionary, such as with a better camera and different shell, but does not support 4G or LTE.Keith Bachman said: “Apple’s LTE phones to be launched in 2012, is so that a poor performance due to the battery.”
