Okay, so solar stills are available, but do not produce a very high
ethanol concentration with distillation. What about using solar
energy to preheat your solution before it reaches a regular still.
If you could preheat with solar power, less energy would need to be

That is also my understanding. The alcohol starts to kill the Yeast
above 10%, and they are nearly all dead by 14%.
On the temp side, 140F kills them off.

freezing causes the yeast's cell wall to rupture,killing

i am still trying to look thru my info to find the vacuum

Thanks. That would much simplify the process, if it can be done
Are you pumping the liquid solution, or
just the vapors?
Just the vapor is moving across. You have space over the liquid and the
air is connected to a cold space that is lower so the cold air is stable.
As the alcohol becomes dew the partial vapor pressure renews the
concentration. A
