Trough battery 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. The inside of this box was lined with shellac for insulation, and pairs of welded-together zinc and copper plates were laid out in this box, evenly spaced. The
Electric clock types of mechanism: In 1814, Sir Francis Ronalds (1788-1873) of London invented the first electric clock. It was powered with dry piles, a high voltage battery with extremely long life but the disadvantage of its electrical properties varying with the weather. He trialled various means of regulating the electricity and these models proved to be reliable across a range of meteorological conditions. In 1815, Giuseppe Zamboni (1776-1846) of Verona invented and showed another electrostatic clock run with dry pile batteries and an oscillating orb. His team produced improved clocks over many years, which were later denoted as "the most elegant
