I got 600-700ml ethanol out of 1L spiritus, which costs about 1,50 euro's, very economical if I may say.


If you didn't have to pay for the electricity, the cooling water, the other chemicals and the manhours involved, then yes.

Well, the magnesium turnigs cost about 25 euro for 500gr at Fisher so that is 0,75 cents but this amount of magnium can be used for a lot more alcohol. The MgSO4 doesn't cost much and is re-used almost indefinitly.

Water is in a closed circuit, so it is'nt used. Ice comes out of a refrigerator which is turned one anyway.

About the electricity I don't know what it costs but it can't be more than 2 euro's.

If you see the work done as a hobby manhoures should be forgot.

So that makes about 7 euro's a liter 99% ethanol, with a price that gets lower if you make larger batches. Normally I pay 9,50 for a liter of 96% denatured ethanol.

Ps. price of sulferic isn't counted in because it's about a milliliter or less.
