Title: 2006 Going offgrid with selfmade alcohol energy
Post by: hallo on November 25, 2005, 05:59:39 AM
Hello,
enclosed is a PDF file I found recently which describes a very
easy process how to produce alcohol from sugar and biowaste products.

Very easily alcohol concentrations of about 50 % can be produced that still
can be enhanced to over 90 % with the repeated process disclosed over here.
This can be used to power your house with alcohol as fuel for heating and cooking
and running a generator to charge your batteries !

So it will be pretty easy to go offgrid in 2006 with this technology of alcohol
generation and extraction.

Yes, this is a very good concept.
I have already bought a alcohol coker and it functions very well.

One possible way to destill the alcohol maybemore efficient from
the solution could be to use an ultrasonic fog generator, which could
gemerate the steam mostly out of the alcohol first and this way the alcohol could
be seperated maybe much simpler and easier than with the heating method.

If anybody still has a better idea, how to seperate the alcohol with even
still less energy from the water-alcohol solution ,please post your ideas.
For cooking and heating at least 80 % alcohol percentage should be used,
I just tried with about 50 % to 50 % water-alcohol mix and there the
alcohol cooker did not work at least not my model, which you can see over here:

With standard 94 % alcohol from Brennspiritus it works very well.

I am cooking now for the first time a pot full of  potatos with ethanol fuel ( Brennspiritus)
on my spiritus cooker.This works pretty good.

Soon I will do my own alcohol and see how it goes.

I think, with a dual mode energy supply:
a) selfmade ethanol for cooking and heating puposes
and
b) solar battery based and charger enhanced battery storage
for powering electrical loads via a good 12 volt to 230(110) Volts inverter
it could be possible to go offgrid.

Regards, Stefan.

Here is the english version still with a few more tips:

I think we have a problem here. Making alcohol out of old fruit from a compost heap is easy enough.

But making alcohol out of bio waste materials requires two further complex stages - steam treating the cellulose material, and using an enzyme to convert the result into a carbohydrate that can be fermented. Does anyone have details of these processes?

Wow, now were talking, Brewing beer is a favorite pastime of mine, a buddy and me have made some great beer. One thing about this that I know for sure and is backed up in all literature for brewing. the more sugar or starches you start with, the more alcohol that will be generated in the end.
part of the process that takes sooo much energy in the beginning is boiling or rather high heating the suger to get them to release the starch that the yeast will consume and turn into alcohol,
The next energy consuming process is distilling the spirits out of solution.
i've not put any thought into this as of yet, (  I'm all over it now)but it seems on the outset, if you can reduce the energy input in both these 2 cases, starch conversion and "boil off" of alcohol. you will be onto something.  Also, you need to find a cheap sugar sorce to start with.. ie malt extract or molasses are not cheap.
In the meantime, I will continue to ponder effective alcohol creation each time I have a home brew.
