caption: The image shows a black and white drawing of a machine with a lot of wires attached to it. At the bottom of the image, there is text which reads "electrolytic". The machine appears to be a large, cylindrical object with a handle on the top and a few wires running along the sides. The wires are connected to the machine and appear to be made of metal. The text is written in a bold font and is surrounded by a thin black border.
