Bio batteries? An interesting idea from Sony:
Sony's new bio cell is totally different, it is organic. Its fuel is a carbohydrate glucose solution, yes, everybody's favorite sweety.
One bio cell unit produces around 0.8V, 50mW. You have to connect quite a few units in series to utilize this feeble power. At least four units are necessary for running a silicon Walkman.
Yes, the word "sweety" was used in the article. Yes, the article was likely translated from another language. Yes, electricity rated in the fractions of watts and volts is very small.
My cell phone battery is 3.6V and 0.950 amp hours. You would need at least 4 or 5 of these bio-cells to power a phone and, if you check out the article, they are no slim-profile lithium ion battery. Still, a very interesting idea. Wonder if the same warnings still apply?
Additionally, this comment is PRICELESS:
If they can only create a cell that runs on body fat. Imagine this...Problem 1# Man has beer belly or Woman worrying about cellulite on big oshiri, Problem 2# Batt low sign on K-tai or PSP? I guess this might be the craze that could take the world by storm. Just attach to problem area and VOILA! Hitting 2 birds with 1 stone. Problem area reduced and you power up your gear!
