Unpredictable future of hydrogen fuel-thinkpad t400 battery , thinkpad t500 battery , thinkpad t40 battery , etc.

March 2007, a "development vehicle power technology, so as to ease traffic pressure on the recommendations of energy" (the "Proposal") written by the expert group and a petition, sent to the relevant departments. "Hydrogen fuel cell vehicles prospects for the future, there are many unpredictable factors. If the hydrogen fuel car of the end, need to go find other technical means, which makes large-scale investment in hydrogen fuel car naught." 26 experts advise If China blindly follow the pace of some multinational companies, a large number of financial, human and material resources fully, "bet" in the hydrogen vehicle research and development, is likely to give as a pillar industry of China's auto industry has brought great harm.

"Supporting this letter is much more than 26 people." Expert who asked not to be named, said the "863 plan, to focus public attention to new energy sources such as hydrogen fuel cars, the government sector-oriented Many car companies to bring pressure and power, many companies regardless of their blind pursuit of power and new energy is very dangerous. "

Hydrogen fuel cell research began in the United States. April 2005, General Motors and Daimler - Chrysler Corporation signed a contract with the U.S. Department of Energy in the next 5 years, hydrogen fuel cell electric vehicle development. A time of "hydrogen energy" concept overwhelming, "hydrogen energy" slogan but also across the oceans to China.

According to these experts say, the so-called "hydrogen energy" is actually using other energy to convert water into hydrogen, then hydrogen as a fuel is converted to power through fuel cells, this process does not "overflow" any "could," " Hydrogen Energy "is actually" hydrogen fuel. "

Coupled with the high cost of fuel cells can not be mass-produced the battery capacity is too small long-distance travel difficult. If these long-term can not be overcome technical difficulties ultimately failed to conquer, then even 100 years after the fuel cell vehicles or electric vehicles will not become mainstream vehicles.

The expert explained that the reason of "hydrogen energy" slogan instead of "hydrogen fuel", the key is to make this concept a lot of people mistakenly think that the use of hydrogen energy could solve the traffic problem, so no matter the banner of "hydrogen energy" under the banner of what to do matter how many R & D resources, spending billions of money are the things should be.

Hydrogen Energy - the future "clean" power?

For China's car manufacturers, there is nothing more important than the control engine technology for doing this. On the one hand, the domestic auto industry active digestion and absorption of foreign advanced production technology gasoline engines, while money in developing new energy when the engine, a conventional engine by 26 domestic and foreign experts questioned the State Council jointly submitted "hydrogen" technical outlook has exposed the letter. Recommendation letter written much: China is a major energy consumer, but not a lot of oil and gas resources.

China's oil imports in 2005 accounted for 42.9%. Dependence on imported oil to China's economic development and national security restriction. As soon as possible to reduce dependence on imported oil, should be targeted for development of vehicle power technology. To this end, we are first in domestic vehicle power technology development are some problems, namely "seeking Yuan Lai solution of water near thirst", "first dug drainage water or Deng to find water," the such circumstances and to its analyzed. Then, put forward as soon as possible through the technology development to reduce pressure on transport energy proposals. Currently, the "hydrogen energy" to bring awareness of the deviation of misunderstanding, thus affecting energy policy to solve the traffic.

Energy is that people get energy from natural sources, nature does not exist a large number of hydrogen, so hydrogen is not energy, but not new energy. Need to produce hydrogen energy conversion, so the hydrogen can be used as energy carrier. "Hydrogen Energy" slogan so many people think that the use of hydrogen energy will solve the traffic problem, it is natural to assume that the development should concentrate on full hydrogen cars. This misunderstanding will affect the government and enterprises to solve the traffic problems of energy policy. As a heavy bomb, the letter in the academic and automotive industry has created a stir, a heated debate and it has started.

To the Opteron 6100-series for servers more than twice as fast as its predecessor, with six cores. AMD promotes energy efficiency and low prices. Chips for four-processor systems, there is no extra cost.

AMD has introduced the new Opteron 6000 Series processor with eight or zwolf cores for server systems. The new series, code-named Magny-Cours is that AMD faster, cheaper and more energy efficient, as the competition’s products.

The new processors with the serial number 6100 - the first series of the 6000-series - are in floating-point up to 119 percent faster than their predecessors to work with six cores. The integer performance is supposedly higher by 88 percent. The clock frequencies of the series amount to 1.7 to 2.4 GHz. Various energy saving techniques such as C1E sleep state to minimize power consumption.

The 6100 processors are both two-CPU as well as for four-CPU systems thinking. According to AMD chips for four-processor systems should not be more expensive than those for systems with two CPUs. The cheapest 6100-processor is the AMD Opteron 6128, 2.0 GHz and eight cores for $ 266. The best Zwolfkernprozessoren, the Opteron 6164 HE (low-energy, 1.7 GHz) and Opteron 6168 (1.9 GHz), cost $ 744. For the performance-top model 6176 SE with twelve cores and 2.3 GHz AMD demanded $ 1386.

It is expected that servers offer manufacturers such as Hewlett-Packard, Dell, and Cray systems soon with AMD’s 6100-processor.

Just recently, Intel had introduced a chip with six cores. The top model of server Xeon 5680 costs $ 1663.

So far, mostly spread processors with two and four cores. Chips with six cores are found mainly in expensive high-end servers. The more cores a processor has, the faster it works in theory. However, the software threads can be distributed to multiple cores in order to use them effectively.
