Sony Develops "Bio Battery" Generating Electricity from Sugar - Achieves world's highest power output for passive-type bio batteries - TOKYO, August 23, 2007- Sony today announced the development of a bio battery1 that generates electricity from carbohydrates (sugar) utilizing enzymes as its catalyst, through the application of power generation principles found in living organisms. Test cells of this bio battery have achieved power output of 50 mW, currently the world's highest level2 for passive-type3 bio batteries. The output of these test cells is sufficient to power music play back on a memory-type Walkman. 4 prototype bio battery units (left) connected to Walkman for playback In order to realize the world's highest power output, Sony developed a system of breaking down sugar to generate electricity that involves efficiently immobilizing enzymes and the mediator (electronic conduction materials) while retaining the activity of the enzymes at the anode. Sony also developed a new cathode structure which efficiently supplies oxygen to the electrode while ensuring that the appropriate water content is maintained. Optimizing the electrolyte for these two technologies has enabled these power output levels to be reached. Sugar is a naturally occurring energy source produced by plants through photosynthesis. It is therefore regenerative, and can be found in most areas of the earth, underlining the potential for sugar-based bio batteries as an ecologically-friendly energy device of the future. Sony will continue its development of immobilization systems, electrode composition and other technologies in order to further enhance power output and durability, with the aim of realizing practical applications for these bio batteries in the future. The research results presented here have been accepted as an academic paper at the 234th American Chemical Society National Meeting & Exposition in Boston, MA USA, and were announced at 11 am local time on August 22, 2007. The bio battery mechanism The newly developed bio battery incorporates an anode consisting of sugar-digesting enzymes and mediator, and a cathode comprising oxygen-reducing enzymes and mediator, either side of a cellophane separator. The anode extracts electrons and hydrogen ions from the sugar(glucose) through enzymatic oxidation as follows: Glucose -> Gluconolactone + 2 H+ + 2 e- The hydrogen ion migrates to the cathode through the separator. Once at the cathode, the hydrogen ions and electrons absorb oxygen from the air to produce water: (1/2) O2 + 2 H+ + 2 e- -> H2O Through this process of electrochemical reaction, the electrons pass through the outer circuit to generate electricity.

Now you can recall your email BS Reporter / New Delhi September 14, 2007 How often you’ve wished you could recall an email which you regret having sent, or which could embarrass you. Fret not, help is here. IBM’s latest offerings in the collaboration platform, Lotus Notes 8 and Domino 8 come with a recall feature that allows you to call back an email that has been sent. Developed over the last 2 years, version 8 is based on the feedback of 25,000 businesses around the world. According to the company, this release is one of the best in terms of collaboration features. It also has significant inputs from IBM’s India labs. More importantly, this version can be accessed on the Blackberry platform too. The software will offer features like email, collaboration, calendar, instant messaging and other office productivity tools and custom applications. It is for the first time that a software is based on the open-source eclipse platform, a departure from the fact that otherwise IBM has in the past used its proprietary technology. Sandesh Bhat, director (design and technology innovation), IBM, said: “The whole idea behind this was to offer users the best in the Web2.0 capabilities. This is also our endeavour to develop the desktop of the future. Lotus Notes 8 is much more than an email service, unlike competitive offerings. Lotus Notes 8 integrates work by building in instant messaging and presence awareness, office tools to create and edit documents, presentations and spreadsheets and infusing a business’ custom applications, including help desk, CRM, sales force, discussion forums, blogs and more. This is all possible as Lotus Notes 8 is built on the programming model of Lotus Expeditor 6.1.1, which is based on eclipse.org open standards. Lotus Expeditor 6.1.1 enables the construction and deployment of enterprise mash-ups, also known as composite applications. Lotus Notes 8 and Domino 8 support a variety of platforms, including Linux and Windows for clients and Windows, Linux, Sun Solaris, AIX and IBM System for servers. The office collaboration market is estimated to be in millions. Frost and Sullivan in one of its reports mentioned that IBM with a 44.5 per cent market share is a market leader in India. http://www.business-standard.com/common/st...t=0&chkFlg=

that's nothing new, lotus notes has been able to do that for many years. the netware one (can't recall its name) can do it too. of course, you can only cancel a sent email to someone that also is using lotus notes. once you send it out on the net to a yahoo account or whatever, it ain't coming back!

crystal radio with nanotube eh? not bad but i am much more impressed with tera-scale computing using 62W processor (80 cores) or to be more precise, I want laptop with it: http://techresearch.intel.com/articles/Tera-Scale/1421.htm although Penryn looks good too http://www.tomshardware.com/2007/10/29/int...th_air_cooling/
