AIRBUS A320 : A SUCCESS STORY SINCE 1986 AIRBUS A380: HARNESSES
Bio-batteries have a very bright future ahead of them |
as test productions and research have been increasing over recent years.
They serve as a new form of energy that is proving to be environmentally friendly,
as well as successful, in producing and reserving energy.
Although the batteries are still being tested before being commercially sold,
several research teams and engineers are working
to further advance the development of these batteries.
One corporation consistently working on the advancement of these bio batteries is Sony.
In fact, Sony has created a bio battery that gives an output power of 50 mW (milliwatts).
This output is enough to power approximately one MP3 player.
Sony, however, is planning to continue their research and development
on bio batteries for commercial use. In the coming years, Sony plans to take bio batteries
to market, starting with toys and devices that require a small amount of energy.
Several other research facilities, such as Stanford and Northeastern, are also in the process
of researching and experimenting with bio batteries as an alternative source of energy.
Since there is glucose in human blood, some research facilities are
also looking towards the medical benefits of bio-batteries
and their possible functions in human bodies. Although this has yet to be further tested,
research continues on the subject surrounding
