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
Sea Lion (battery-electric locomotive) Bear", using the frames of 1953-built Wingrove & Rogers loco no. 5031, which has been used at Amberley as a spares donor. The replica would be built initially as a static exhibit, with the potential for it to be made operational. Sea Lion (battery-electric locomotive) Sea Lion was a 2-foot gauge battery-electric locomotive built by Wingrove & Rogers in 1921 as works no. 313 for the Groudle Glen Railway on the Isle of Man. Together with its sister, "Polar Bear", it was intended that they would replace two Bagnall steam locos of the same names. However, the battery locos were
