4 prototype bio battery units connected to Walkman for playback
Following up on my previous post kinetic vs electric toys by Sony, Sony also developed a bio battery prototype that generates electricity from sugar, similar to the method used in living organisms. 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.
As humans breakdown food for energy, the battery would generate electricity by breaking down carbohydrates or sugars through the use of enzymes. Since sugar is a natural energy source, the bio battery would be an environmentally friendly choice as it would dramatically reduce disposal issues with disposable batteries used today.
Test cells have generated up to 50 milliwatts, which is the highest for a bio battery of this type according to Sony. Currently, it produces just enough to power music play back on a memory-type Walkman. Thank you Got 2 be green for the source!
