when was the battery invented?
one of the most important discoveries in the last 400 years has been electricity.
you may ask, "has electricity been around that long?" the answer is "yes", and
perhaps
much longer. surprisingly, electricity only became useful to humanity in the late

the earliest known methods of generating electricity were by creating a static charge.
alessandro volta (1745-1827) invented the so-called "electric pistol" by which an
electrical wire was placed in a jar filled with methane gas. by sending an electrical
spark through the wire, the jar would explode.acer PA-1750-04 Adapter
volta then thought of using this invention to provide long distance communications,
albeit only one boolean bit. an iron wire supported by wooden poles was to be strung
from como to milan in italy. at the receiving end, the wire would terminate in a jar
filled with methane gas. on command, an electrical spark is sent by wire that would
cause a detonation to signal a coded event. this communications link was never built.

the next stage of generating electricity was through electrolysis. volta discovered in
1800 that a continuous flow of electrical force was possible when using certain
fluids as conductors to promote a chemical reaction between metals. volta
discovered further that the voltage would increase when voltaic cells were stacked.
this led to the invention of the battery.Acer TravelMate 600 AC Adapter
from the availability of a battery, experiments were no longer limited to a brief
display of sparks that lasted a fraction of a second. a seemingly endless stream of
electric current was now available.

in the early 1800, france was approaching the height of scientific advancements
and new ideas were welcomed with open arms to support the political agenda. by
invitation, volta addressed the institute of france in a series of lectures in which
napoleon bonaparte was present. napoleon himself helped with the experiments,
