IBM [NYSE: IBM breaks Record] World Solar Efficiency
The solar cells that do not have expensive items mentioned tend to perform not more than 6.7 percent. Apart from bein g more efficient, the new IBM solar cell is also cheaper in terms of printing costs, casting slit and dip and spray coating, since it uses a mixture of solution and nanoparticle-based method instead of the old vacuum method. IBM lead researcher Dr. David Mitzi said IBM is close to developing solar technology that is profitable, while at the same time has the ability to implement terawatt level. Scientists IBM uses a large lens to concentrate the sun's energy - a technology known as concentrator photovoltaics, or CPV-to convert sunlight into 70 watts of electricity. IBM output is said to be five times the power density produced by other solar farms using CPV technology. In 2008, IBM developed the technology photovoltaic concentration with the aim of reducing the production cost of solar energy through photovoltaic cells in less than a solar farm and concentrating more light in each cell using larger lenses. IBM's strategy stems from its ability to cool the tiny solar cell and concentrate the equivalent of 2000 suns on a small area for casting stainless steel. IBM also uses its technology for cooling computer chips to solar cells had been allowed to cool more than 1600 degrees Celsius to just 85 degrees Celsius. IBM has also developed a system that achieved breakthrough results through the combination of a solar cell business with an advanced IBM liquid metal cooling system using thermal methods the microprocessor industry. The cast metal thermal fluid called interface layer is applied between the chip and the cooling block so the heat can be transferred and the chip temperature is kept low. The technology, which was developed originally developed by IBM to cool computer chips, high power, with excellent thermal performance at low cost. CPV technology has the ability to provide lowest cost electricity generation large-scale solar energy, as long as the cell temperature remains low and cost perspective can be developed to concentrate the light at high levels. Out of photovoltaic research, IBM is also involved in energy efficiency technology and services, management advanced water, carbon management, intelligent transportation systems and intelligent services. IBM Research scientist leading photovoltaics Dr. Supratik Guha, said he believes that IBM can provide the knowledge of his extensive experience in semiconductors and nanotechnology to the field of energy research alternatives.

Laptop Sound suddenly does not work, but when I connect the headphones, the sound of the headset works well?
The sound on my computer IBM laptop suddenly stopped working ... The sound was fine until I connect a headset to watch a movie (did not want to bother anyone) and that worked fine. Then shut down the laptop, when it turns back on again and tried to listen to some music (iTunes) sound does not work (This was without headphones). He tried to music in Windows Media Player too, but the sound did not work well and the system sounds are not playing. When I plugged new headphones, the sound of the headset works well. I went to control panel> sounds and audio devices> advanced volume control and turned all volumes up right ... and none of them was 'mute'. The portable volume is up as well. Sound still does not work (except headphones) ... How I can fix this? Thanks in advance.
The laptop's internal speakers are broken. Should be delivered to a store to get it fixed.
