Notebook charging times at any time
Hearing, according to China's cell network Nikkei BP news agency reported each person may have had a sudden fear walked notebook battery computer or mobile phone "battery exhausted" experience. Or regret at this time "how not properly recharged", or looking around to see "where there is an electrical outlet." But perhaps soon no longer have such a worry about the times. The reason why so many say this because the radio waves transmitted through the power of technology is constantly moving forward.
Nomenclature of this technology is called "microwave transmission", the first known from the "SPS" (Solar Power Satellite) concept ibm battery, that is, in the universe to build a huge solar power stations, the electricity generated will be sent through the microwave antenna on the ground, it can replace the power station, which is a science fiction-like idea. If the construction of the great cosmic power stations generate electricity continuously, then its generating capacity could reach 10 million kilowatts, equivalent to 10 nuclear power plants. These microwave covered with earth, such as portable phones and PDA devices can also use it as a power supply. Power to the air falling to a "bath of energy," then perhaps some more easy to understand.
However, this science fiction-like in order to achieve the ambitious plans also need to overcome a lot of big problems.
First of all, radio waves from the air, will worry about the human body on impact. Microwave transmission in fact equivalent to the principle of microwave ovens. Therefore, the electromagnetic wave is still to limit the output power from the cosmic microwave fired power stations, and its output power must be within limits. If the restrictions in this standard for microwave power transmission, they will be able to realize the power generation.
SPS plans but there are still more problems. The universe to build a huge power station to the space of about 50,000 tons transporting equipment. The transportation of these goods, even if is to develop launch capabilities of the H2A rocket to exceed the current 20 tons of rockets, the launch also need to do 2500 times.
SPS study conducted in Japan the first person - Kyoto University Professor Matsumoto Hong said: "is now 10 to 20 years for a trial basis after the construction of 10,000 kilowatts universe of small-class power stations and a variety of experimental efforts." Japan Ministry of Internal Affairs and the Ministry of Education, Culture and as the center, also began the study of national projects.
No cruise fuel cell detector distance of 317km endurance test
Marine research and development agency of Japan has announced that the unmanned probe-based deep-sea cruise "URASIMA" successfully completed the long-range test. The detector using the entire closed fuel cells, the distance between the aircraft continued to reach 317km, cruise detectors in the world's first set of records. The agency from February 26, 2005 in Suruga Bay to carry out performance tests of the detector, the long-distance running success is in the process of the pilot realized.
The use of the full closure of the fuel cell at the same time hydrogen fuel and oxygen storage case with the internal probe, and even water power generated can also be stored in the fuel cell pressure container. Navigation in the sea, the common battery is difficult to obtain oxygen from seawater, but also great power in high-pressure power generation from the next generation of water, so the weight will not be able to maintain a balance, so to make up for these shortcomings, the use of the above . The fuel cell is equipped with, in the power generation part of the latest technology with the use of metal separators, and storage of hydrogen fuel using a newly developed hydrogen storage alloy, the performance test showed that the energy efficiency of fuel cells more than 54%.
URASIMA is a seabed survey of deep-sea earthquake ibm thinkpad t40 battery, ibm thinkpad t40p battery, as well as to investigate the earth's greenhouse effect and the development of detectors no one type of deep-sea cruise. Built-in detector side of the computer program in accordance with a pre-determined calculation of their position to the side navigation. And water navigation vessels and aircraft-style drag compared to Sham tools can not affected under the premise of the wave detection, so the image can be more subtle. The long-distance running in the success, so it possible to expand the detection range, it is estimated that the investigation can be increased to the rate of about 3 times.
The performance test is a central part of Suruga Bay in the north-south demarcation of 25km, East and West 2km, deep within 800m of the sea. February 25, 2005, the detector with auxiliary mother "Yokosuka" from its headquarters in the exclusive riverside Yokosuka starting in the next day at 17 o'clock on the 26th to start to experiment. At 19:10 on the 26th to start of navigation dive. For navigation until at 15:10 on the 27th, the entire 56 hours after the voyage. Previously, the maximum cruising range from the detector recorded by the British Institute of Oceanography Southampton unmanned probes "AUTOSUB" creation, at the time recorded as 262km.
Nano Rechargeable Battery
According to "New Scientist" magazine reported that the United States, Nevada's Altair Nano Science and Technology Corporation recently announced that it has in the lithium-ion battery technology have made a major breakthrough, the company will market a new generation of filling can be battery products. Altiar new technologies used to create a new type of rechargeable battery that can be 6 minutes of full power and at the same time re-use of an electric current ordinary hours of rechargeable lithium batteries 10 times and its electricity, compared with 3 times.
Altair particles developed a new type of lithium battery anodes using titanium nanocrystals of lithium, the anode surface area to 100 square meters per gram, while the traditional lithium battery carbon anode particles of the surface area of 3 square meters per gram. Large enough in surface area on the basis of the electronic can enter and leave quickly, so fast charging is possible, at the same time the provision of high-current has become a reality.
In addition, a new type of lithium battery particles particles of lithium batteries are the traditional advantages unmatched. The surface of traditional carbon anodes used in the battery charging process and can easily withstand the impact of changing temperature. This has limited the number of its charge for about 400 times. The lithium-titanium anode comprising nano-crystalline surface temperature to be much smaller, it can charge a staggering number of 20,000 times! The extension of battery life, rechargeable battery on the environment pollution will be significantly lower.
Altair Corporation is scheduled to be in two years into a new type of nano-ibm thinkpad t41 battery, ibm thinkpad t41p battery market. Demand for battery power electronic devices such as mobile phones, notebook computers, the Gospel is great. The near future, perhaps a red phone to power in January, but laptop battery life to several tens of hours, we need to do is to not charge too much ease frequency the charge, although it is only a few minutes.
