You could use a Carbon dioxide scrubber to remove the CO2 and then still
be able to use a vacuum for distillation.

As long as this is still in the theory stage: Remember that ethanol
is an excellant cleaning solvent. You will need to pay extra special
attention to your 2 cylinder compressor to make sure the essential
mechanical parts are still being oiled. The ethanol vapor will tend
to wash the cylinde

Well, you are now talking about vacuum fermentation for which there is a
patented process. Stripping off ethanol as it is produced solves one problem
but the problem is that the vacuum system must deal with the massive amounts
of carbon dioxide being generated by the fermentation process; so va

Not yet, but it may 'accidently' occur occasionaly. I may have to
further purify a small sample occasionally for 'lab tests'!

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

Motie,

west process of all but uses the least energy.
Just some meandering round Robin Hood's barn but I think there is a seed or
two in there.

This is one of the reasons that The Revenoor Co.

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.
That
I think yeast croak or really slow down at 14% or higher.(14%=28proof)

if you make your solar collector strong enought,you
can use vacuum distillation at solar collector
temperatures to distill ethanol.

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
