Hi,
The process for production of ethanol from starchy material e.g. Corn,
potato, cassava etc. is offered by an Indian Company. The details are

Hi, Flashyrider
About converting your engine, I have never done it, but I can tell you what
I have seen in some 4 stroke/4 cylinders 1.3 L to 2.0 L ethanol powered
Brazilian cars with some special devices installed at factory
a) They changes the compression ratio to about 1/15 by diminishing
the
volume on the upper head of the combustion chamber (so you get maximum
efficiency from ethanol that withstand high compression ratios)
b) The ethanol needs to over 30¡ C room temperature to have enough
amount
of evaporation in carburettor, so they should add a preheating device or
use an automatic controlled starting mixture of high octane gasoline or
that is turn off when the engine reaches its working temp.
c) You might add after the carburettor a hot comb or fingers made
of
aluminium in contact with some part of the exhaust as a heat exchanger,
and add to the air intake a metal hose or cover around the exhaust of the
engine if you are living in some cold climate country.
Best regards,
Juan Boveda

Hi, I'm a new member to this group and if anyone could answer my
questions I would be very grateful.'
1. What is the best recipe for converting potatoes to ethanol.
Specifically, I have a recipe that says to just boil the potatoes and
use only the liquid for fermentation. Is that the best way, or should
I mash up the potatoes and try to convert all the starch?
2. Does anyone have a good recipe for converting corn to ethanol?
3. I built a valved reflux still and I need to know what is the best
packing to use in the column. Right now, I'm using glass marbles with
a 1/2 diameter. I have heard of using Raschig rings. Are they more
efficient? How about steel wool?
4. I would like to convert my 2 cycle lawnmower to run on ethanol
fuel. Any suggestions on engine conversion?
Thanx.
