Electricity is found throughout the human body. The flow of charged ions causes your heart to beat and your muscles to contract. But nowhere in the body is electrical activity better documented than the brain, which contains roughly a hundred billion electrically conductive, biological wires.

Every time a neuron ‘fires’ it produces a tiny change in voltage that causes an even more minute amount of current to flow – approximately one nanoamp – according to biophysicist Bertil Hille of the University of Washington.
One calorie is equivalent to 4,200 joules, so if someone eats 2,000 calories a day, they are consuming around eight million joules.
If 800 million neurons are active at once, the electricity output is equivalent to about 0.085 Watts of power, which is around the same amount of electricity needed to power and energy-saving LED bulb.
According to gizmodo, If you could somehow divert every single biological wire in your skull to your iPhone’s battery, you’d be fully charged in just under seventy hours! Huh! That doesn’t sound particularly efficient, especially when compared to a standard wall charger, which usually does the trick in under an seventy minutes.
