Electrical engineering credited with establishing the term "electricity". He also designed the versorium: a device that detects the presence of statically charged objects. In 1762 Swedish professor Johan Carl Wilcke invented a device later named electrophorus that produced a static electric charge. By 1800 Alessandro Volta had developed the voltaic pile, a forerunner of the electric battery In the 19th century, research into the subject started to intensify. Notable developments in this century include the work of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, of Michael Faraday (the discoverer of electromagnetic
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
