I am working on a lexan box with several tubes from one end to the other, and using air from the smog pump to cool the 'juice', there is a thin chamber on each end of the box which has plates inside, arranged vertically in 6 groups of 10 plates, + n n - n n + n n -, with both anodes connected to one bolt, and both cathodes to one bolt, with straps to each 'cell' unit, making one positive connection and one neg connection for each box, also making 3 and 4 unit boxes for smaller engines, or for divided installations due to space limitations
