The column efficiency starts to drop once you move from 2" to 3".
When you move to 4" it drops markedly. This means that by just
scaling up a 2" design to 4" you are not going to get 95.6% ethanol
four times faster.
It is indeed the case that you would be better off making another
type of a still if it is easy neutral alcohol production you have in
mind. Look for VM, ARC and E-ARC type of stills.
