This was one of the first types of demonstration for bio-fuel cells. The fact that the energy can be used to recharge various gadgets will make the technology sell like hot cakes. Furthermore, these devices have the potential to replace environmentally unfriendly rechargeable batteries. The idea is mainly based upon billions of invisible cells working in unison.
As you all know the human body comprises of inside structures called organelles and one such essential organelle is mitochondria. Famously known as the powerhouses within cells, they are capable of transforming calories within food into a form of energy that becomes readily available to cells. Skipping the specifications, let us move straight to the point. This small unit is capable of generating energy equivalent to the body weight of an individual. Now that is huge provided how insignificant they are in size.
The question is what this has to do with recharging of your electronic devices. Actually they have got everything to do with it. It is this energy generating system that opened up ways to develop a fuel cell solely with mitochondria. This is what a team of researchers have been successful in doing.
