I don't know if this a new technology or just a new application for current tech, seems pretty cool either way! I'm sure there could be quite few
other applications for this 'bio battery' aswell.
From the sorce:
Ms Zheng said the prototype could run up to four times longer than a traditional lithium ion battery and has the potential to be fully biodegradable.
The greenphone's bio battery generates electricity using enzymes to catalyse sugar in the drink. As the battery dies out, only water and oxygen are
left behind. Unfortunately, Nokia will not be developing the greenphone prototype further in the near future. Ms Zheng told Sky News: "At the time
they wanted something to bring out within the next two years and thought my design was too futuristic." But she added that bio batteries are being
developed by large electronics companies and may be on the market in the next five years.
and heres a link to the source: Sky News
Woudn't it be great if this type of battery could replace existing, enviromentaly hazardous batterys! I've never heard of a battery that works by
converting sugars into electricity before, I'm going to see if I can find some more info and scientific data on this.
