Video demonstration of Sony's sugar powered battery

Some Sugar spice and anything thats nice! :P
Sony demonstrated how the sugar powered battery works. This battery is going to replace lithium batteries in future as a clean energy solution.

Its a video by ITworld.com on youtube ( The only one I found on youtube). You can also watch another published by PC World here.

Sony Develops 'Bio Battery' Generating Electricity from Sugar

Sony (on 23 August 2007) announced the development of a bio battery 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 level for passive-type bio batteries. The output of these test cells is sufficient to power music play back on a memory-type Walkman.

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 is going to 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 yesterday.

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.

Sony Rolls Out Bigger PS3, Cuts Price of Existing Model

Starting Monday, the current 60-gigabyte PlayStation3 model will cost $499, down from $599.

The Japanese electronics maker said it is introducing a new version of the PlayStation 3 with a bigger hard drive for storing downloaded content such as video games and high-definition movies.

The new PS3 increases the system's storage capacity to 80 gigabytes from 60 gigabytes and also includes a retail copy of the online racing title "MotorStorm," a company spokesman said. It will be priced at $599.

The larger capacity machine won't be available in the United States and Canada until August.

It plays into the company's upcoming strategy of eventually offering downloaded high-definition movies, video games, movie trailers and demos, Sony spokesman David Karraker said.

Nintendo, meanwhile, claims it has sold nearly 6 million Wiis worldwide as of March 31, and more than 40 million Nintendo DS handhelds. The company has predicted it will sell another 14 million Wiis and 22 million additional DS systems by the end of the current fiscal year.

The Wii and PS3 were released within days of each other late last year. Microsoft had a head start in the current generation of consoles, having launched its Xbox 360 in 2005.

Last week, the software company announced an extension of the warranty due to the high number of systems suffering from hardware failure, also called the "red ring of death."

In April, Microsoft began selling a version of its Xbox 360 with a 120-gigabyte hard drive and a souped-up high-definition video connection. Called the Xbox 360 Elite, the black-colored system sells for $479.99.

Xbox gamers who already own the $399.99 20-gigabyte model can buy a snap-on 120-gigabyte hard drive for $179.99.
