Battery technology will be fried to the era of hand-cranked power?
Edison is said to be the invention of the first lithium 1691P battery, but it was not until 1992, Sony Corporation of the unknown from a small research institute in Japan bought a really practical, and industrialization of patented technology for lithium batteries. Lithium batteries from the laboratory to the market took a whole 100 years, scientific and technological progress every cost.
However, only 14 years after, Sony is necessary for the lithium batteries will have an even heavier price - as a result of the use of Sony lithium batteries because of overheating of the notebook again and caused the fire, including Dell, HP, Lenovo, Apple, Toshiba, Fujitsu almost like the name of the major computer companies have announced a recall of notebook computer battery problem, and now the latest to join the ranks of the Acer computer. Sony had to spend more than 300 million U.S. dollars to calm down on the lithium batteries do not trust.
On the previous two days, I see Ponte author of young children for the global planning of the 100 U.S. dollars in particular notebook 1G222 computer safety measures to be adopted may be low and its economic model, as revolutionary significance. The Massachusetts Institute of Technology, founded by the non-profit scheme, "every child a laptop" goal is to provide for their children through a colorful, hand power to support wireless Internet access for mobile computers to improve education.
So I note that this summary of the 100 U.S. dollars on the notebook computer 1X793 power hand. It seems the safety of our children can be guaranteed, and do not know or for the safety of a coincidence.
I think of the recent well-intentioned people often receive the message "Do not put the computer on the thigh", "Please use the notebook computer when you plug in the power" and "advice." I thought to myself, this is the notebook computer can you move?
On the mere mention of the battery, or even whether the battery up a bit of an overkill mean? As far as I know, precisely because of the emergence of lithium batteries, the first time to allow practical use of artificial cardiac pacemakers possible. In this it seems to enter the "era of hand-cranked power generation", also requested more time to science and technology.
Fuel cell to enhance combat capability of the submarine
In 1990, the shipyard design Type 212 submarines - the world's first fuel cell-based and equipment-type "do not rely on air propulsion" (AIP) submarine system. Because of the 212 Italian Navy submarines are very interested in, it is proposed to improve its design, such as increased deep-diving, using the new external communications systems and escape equipment. German navy adopted these recommendations, produced 212A submarines. German Navy 212A submarines for the basic requirements are: to overcome the shortcomings of 206A submarines 6Y270, operational performance can not be reduced; the installation of fuel cell systems and diesel-electric hybrid power system of the power plant; submarine underwater life type 206A to raise at least 4 times; submarine's total life (fuel cell system with a diesel-powered endurance system) remains unchanged; the use of fuel cell power system, the maximum underwater speed of not less than 6; fuel cell power systems are installed with the main equipment 6.5 meters in length within 75uyf the subparagraph.
212A of the main characteristics of submarines in the power plant. In addition to 16-cylinder diesel engine and conventional lead-oxygen battery, but also assembled in 9 groups of hydrogen fuel cell modules, each providing power 30-50 kW. Gaseous hydrogen fuel is not stored or compressed form, while the form of metal hydride storage, the metal oxide to a large number of absorption, retention and decomposition of hydrogen fuel. Each storage unit by the several groups composed of metal hydrides, which store hydrogen fuel than the low-temperature container, but also in a closed combustion chamber is very convenient to use. Fuel cell power systems with high utilization of energy, no noise, low heat, no gas and so on. Alone hydrogen fuel cell-powered system, ventilation because they are not surfaced, the submarine can be submerged for about two weeks; if used alone diesel - electric power systems, submarines, every 2 to 3 days to be surfaced for the use of snorkel rechargeable batteries. Chai combat power necessary to obtain high-speed, fuel cell systems for a long time hidden underwater navigation. Combination of the two sets of dynamical systems can also be used alone at the same time, greatly enhance the survival of the submarine and combat C1295 capability.
Aerospace fuel cell power generation system project passed the acceptance
October 9, China's space industry in the 50th anniversary of the creation GD761, by the Beijing Space Science and Technology Corporation, a joint 11 and 811 Beijing Institute of Technology shared the basis of national defense research projects, "the application of fuel cell power generation system research" and smoothly in Beijing adopted CSTIND inspection organizations, it is dual-use space technology to enter another bear fruit.
Fuel cell power generation system with high specific energy, low temperature, non-polluting, long-life, renewable resources and maintaining the advantages of simplicity, in the aerospace, aviation, ships, vehicles and other areas have very broad application prospects. Since 2001, Beijing, 11 on the hydrogen-oxygen rocket engine started to use dual-use technology for hydrogen fuel-cell power generation system of basic research. In Defense and Aerospace Science and Technology Corporation under the leadership and support, "the application of fuel cell power generation system research" on the KD476 project in October 2003, three units from nearly 80-member project team to actively explore and practice of research with combination of management style, have captured a high-performance hydrogen fuel cell group, high-pressure fuel cell engine and vehicle more than 19 energy management a key technology, successfully developed the first domestic high-pressure hydrogen cars fuel cell hybrid vehicles like light, made 7 patents and 21 proprietary technology and is applying for 10 patents, for the "Eleventh Five-Year" national defense-related projects TD347 based on scientific research has laid a solid foundation, but also will promote China's fuel cell power generation system in the dual-use developments in the field.
The scene in the acceptance by the Iveco van-like vehicles adapted to carry out a demonstration also. Vehicle weight 4930 kilograms, a total of 10 seats, the maximum speed of 915 kilometers, has successfully conducted more than two hundred kilometers of trouble-free road test, and in August 2006 in the Ministry of Transportation completed a road test site performance testing. The subject for the experts gave a high evaluation U4873, and recommended equipment for the green industry and contribute to the Olympic Games to further deepen the study, at the same time actively adopt effective mode of combination.
