Stanford scientists to double Wi-Fi speeds
Scientists at Stanford University said they have found a way to double the speed of Wi-Fi networks. The technology could send and receive information at the same time where it previously had to work in a single direction. Philip Levis, the assistant professor of computer science and electrical engineering at Stanford and in charge of the project, likened it to people shouting at each other at the same time: oth people in such a shouting match can screen out the sound of their own voice, but hear the other person, he said.
Google Fiber picks delayed to early 2011
Google on Wednesday said it was pushing back its decision on the cities for Google Fiber to early 2011. It had originally planned to detail the cities and areas getting 1Gbps Internet access but was "not quite ready" to say which ones. Almost 1,100 communities responded and overwhelmed the company, Google said.
System utilizes heat and light for conversion
Engineers at Stanford University are working on new technology that aims to double the efficiency of existing solar energy systems. Researchers are testing a conversion method, "photon enhanced thermionic emission," that thrives in higher temperatures, overcoming a drawback of traditional photovoltaic technology that becomes less efficient as temperatures rise.
iPhones for freshmen
Abilene Christian University will be delivering an Apple iPhone or iPod Touch to all members of its incoming class in 2008. Freshmen will use the iPhones or iPod Touches to receive homework alerts, answer in-class surveys and quizzes, get directions to their professors' offices, and check their meal and account balances - "among more than 15 other useful web applications already developed," said ACU Chief Information Officer Kevin Roberts. Roberts was asked to present ACU's creative vision for converged media devices at Apple headquarters to executives and to selected leaders from universities including Harvard, Yale, MIT, Duke, Stanford, Oxford, Princeton and UCLA.
Stanford Lively Arts cards
Stanford University is teaming up with iTunes to provide Lively Arts gift cards, a sampler card that offers attendees to the Lively Arts events 10 free downloads of featured artists. The iTunes sampler card will be given out from January 25th until March 15th at the various events, and will also be available to users through various campus services. Students who can't attend the Lively Arts events can pick up a complimentary card at the Stanford Bookstoor, Tresidder Express, Track House Sport Shop, The Stanford Shop, and The Bookshop at the Cantor Art Center.
Stanford Nanowire Battery
A new nanotechnology development should produce a major increase in the power available from lithium-ion battery technology, according to a report from Stanford University. While current batteries are limited to holding a relatively small amount of lithium by the need to use carbon for the anode that supplies the battery's current, the new technique developed by assistant professor Yi Cui instead uses a nest of silicon nanowires to hold the lithium. This allows far more lithium to fit into the battery while avoiding the swelling damage that occurs if larger silicon patterns are used.
