139. Brainpower

The brain uses electricity, but how much? When measured in terms of Watts the human brain expends 20W of power. That is not much.

In fact you would need 5 human brains together to provide the same energy as an average laptop. So yes, brains are not a brilliant source of power. Back to batteries – for now. On the bright side though, a single human brain expends the same energy used by 18 mobile phones.
