Think of Volta and his electric piles. Electricity generated by moving
wires past magnets was a later development, but there was battery power
in the 18th C.

ISTR the device required an engraved copper plate for sending and synchronized
pendula, one on each end of the transmission. I think the receiving paper was
treated in some way to change color when exposed to an electric current. It
wasn't very efficient, but to be able to transmit an image over a distance at
all was quite a feat for its day. The practical application had to wait until
the development of a national communications infrastructure.

One of my favorite quotes from the telecommunications industry was a fellow
who was chided for his enthusiasm about the new telephones. After all, we
had the telegraph - who really needs to speak person-to-person all that
badly. His (paraphrased) response: "The telephone is a wonderful device. I
think at some point, every city will have one."
