Electric battery common fuels such as gasoline. In automobiles, this is somewhat offset by the higher efficiency of electric motors in converting chemical energy to mechanical work, compared to combustion engines. The usage of "battery" to describe a group of electrical devices dates to Benjamin Franklin, who in 1748 described multiple Leyden jars by analogy to a battery of cannon (Benjamin Franklin borrowed the term "battery" from the military, which refers to weapons functioning together). Italian physicist Alessandro Volta built and described the first electrochemical battery, the voltaic pile, in 1800. This was a stack of copper and zinc plates, separated by
Who Killed the Electric Car? a marginal amount of hydrogen fuel cell cars to be produced in the future, versus the immediate continued growth of its electric car requirement. Footage shot in the meetings showed Lloyd shutting down battery electric car proponents while giving the car makers all the time they wanted to make their points. The hydrogen fuel cell was presented by the film as an alternative that distracts attention from the real and immediate potential of electric vehicles to an unlikely future possibility embraced by auto makers, oil companies and a pro-business administration in order to buy time and profits for the status
