The truth is that our batteries aren’t so good, being not much better than the voltaic pile battery invented more than 200 years ago by Alessandro Volta.
But now, a new discovery in this field could make out batteries much more efficient. Researchers claim they’ve discovered a new power source. According to them, a biofuel cell implemented in our arms that uses oxygen and sugar from blood could generate electricity.
The scientists are looking for compact, lightweight, dependable ways for astronauts to power space-borne electronics such as medical sensors. In the meanwhile, a satellite equipped with a biofuel cell powered by tanks of oxygen and sugar will be sent into orbit to see how well it does.
