The portable water cooler/supplier for homebrew distillation is made out of junk parts from the local junkyard for a few bucks.

The cooler was built with a straightforward thought - to make it possible to run an alcohol distillation without dependence on the main water supply. And also when the water consumption is limited. Thus this cooler can operate with just 6L of water enough to carry on many distillations in the row. The cooler makes it possible to save precious water. For example, to make one wash load for 25L alcohol still will take 14L of water. But to run a complete distillation will take over 200L of cooling water. If this water comes from a tap and goes from still directly to the drain, it is more than wasteful.
