In theory, electricity created by your brain could charge an iPhone 5C in 70 hours, however there is no known way to harness that electricity.

Gizmodo’s Maddie Stone determined that, in theory, the power generated by your brain could charge an iPhone 5C in 70 hours.

Everything we do is controlled and facilitated by electrical signals running through our bodies. The brain has a hundred billion electrically conductive “wires,” Stone explained. 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. While this is a minuscule amount, the human brain contains approximately 80 billion neurons and it’s thought that one per cent is firing at any moment.

In order to charge an iPhone 5C, which holds a charge of 5.74 Watt hours, the brain would take approximately 68 hours to charge the smartphone. Stone said, “That doesn’t sound particularly efficient, especially when compared to a standard wall charger, which usually does the trick in under seventy minutes,” noting that there is no way of harvesting the energy from the brain. However, if we could, it could still be problematic as there would be no spare electricity to carry out all the other necessary actions needed for the body to function.

Even if only one per cent of the brain’s electricity was diverted to charge a smartphone, it would take about 285 days to charge the same smartphone.

And Chris Smith, a medical consultant at Cambridge University determined that it would take around six days to charge a human using a USB cable.
