Sony's 'Bio Battery' Generates Electricity from Sugar

Sony today 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.

billyea said,
I think you might be onto something.
Of course, there's probably a reason they haven't done that.

yea, its the lobbyists of the med's

world wide debate about ecologically good energy sources + this:

Stop eating your donuts, policemen! use energy wisely!
-police man: OH NOOOOOOOOOOOOOE!
:laugh:

I can't believe every comment is negative. This has real potential as a renewable clean source of battery power. I can't believe how much of a fad hating sony has become. I could understand if YOUR battery exploded, but it probably didn't. It just became cool to hate sony. The battery in the picture looks pretty large, but how can you not be impressed or at least see that is an important achievement? As you are all aware, current battery technology has its disadvantages.

I'm pretty sure everyone is joking, and some comments are tongue in cheek about sony's problem with batteries. It's unrelated, but no one said anything negative about the bio battery. Just your regular unconstructive comments.

Next on Sony's plate: human waste power. Stick a tube up your butt and feces into methane power for your power suit. You plug all your electronics into the suit,

Disclaimer: Sony is not responsible for internal bleeding caused by explosion of the PowerIV product within one's body. Injection is done at owners risk with no implied warranty.

For ANY piece of technology, they would need to test this thing heavily before it even comes close to my body.

Wouldn't want to be around if it did bet that would leave a sticky mess everywhere and attract flies by the ton.

On a more serious note, Good idea wander how long until they managed to make them commercially viable.
