Information theory began as a bridge from mathematics to electrical engineering and from there to computing.
We're made up of energy, so who's to say you can't transmit through electrical means? If you could transmit yourself wirelessly, then it's Armageddon pretty much.
Electrical science has revealed to us the true nature of light, has provided us with innumerable appliances and instruments of precision, and has thereby vastly added to the exactness of our knowledge.
Neuroscientists talk a lot about brain circuits. In fact, the word 'circuit' is probably misleading. We do not know where most circuits begin and end. And unlike an electrical circuit, brain connections are heavily reciprocal and recursive, so that a direction of information flow can be inferred but sometimes not proven.
The fuel cell is just a fundamentally inferior way of delivering electrical energy to an electric motor than batteries.
