Trough battery spaces between the plates (the troughs) were filled with dilute sulfuric acid. So long as the box was not knocked about, there was no risk of electrolyte spillage. Trough battery The trough battery was a variant of Alessandro Volta's Voltaic Pile and was invented by William Cruickshank c. 1800. Volta's battery consisted of brine-soaked pieces of cloth sandwiched between zinc and copper discs, piled in a stack. This resulted in electrolyte leakage as the weight of the discs squeezed the electrolyte out of the cloth. Cruickshank solved this problem by laying the battery on its side in a rectangular box.
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
