TAILIEUCHUNG - The next great telecom revolution phần 9

Thêm vào đó, nội dung highfrequency có thể phát hiện các chi tiết của các đối tượng ", Buehrer. Khả năng này, kết hợp với năng lượng thấp của công nghệ, làm cho UWB radar một công cụ giám sát tuyệt vời. UWB cũng có tiềm năng để trở thành một phương tiện thông tin liên lạc quân sự đáng kể. "Bởi vì mức thấp | SMALLER LIGHTER POWER ADAPTER 181 retired mechanical engineer says Dynaglass was developed in the mid-1990s but some of the technology is based on research by the Soviet military and space programs. He learned about the material while helping a friend ship medical supplies to Russia. Later on we discovered that the material could be used to store energy says Baldwin who then formed a company Columbus Ohio-based Dynelec to explore the technology s potential. Baldwin boasts that Dynaglass is a remarkable power source. A Dynaglass battery he says is infinitely rechargeable and might be able to generate up to 30 times more energy than a lead-acid battery of comparable size and weight. The device which can be produced in a wide range of sizes also contains no acids or other dangerous chemicals making it pollution free. It just reacts like glass Baldwin says. But since Dynaglass isn t brittle like ordinary glass it s durable and won t shatter when dropped. While a working Dynaglass battery would be warmly received by mobile device manufacturers and users Keith Keefer a scientist based in Richland Washington is skeptical that Baldwin s technology is all that it s purported to be. He notes that several inventors have created similar devices and that none of the devices has lived up to its promise. No one has ever really made it work he says. Yet Baldwin is looking to interest manufacturers in his technology. A glass producer could use this to enter the energy industry at practically no additional cost he says. Ion Trek Mobile phones CD players and flashlights all wear down batteries far faster than we might wish. Researchers at the . Department of Energy s Idaho National Engineering and Environmental Laboratory however have overcome another barrier to building more powerful longer-lasting lithium-based batteries. The team led by inorganic chemist Thomas Luther has discovered how lithium ions move through the flexible membrane that powers their patented .
