Great find.

Just looking at the stock market, I think if you buy in BULK BULK BULK sugar is about 12 cents to 15 cents per pound. Saw from Brazil sugar is $190 per metric ton... if you buy 1 million metric tons. I think a metric ton is 2,200 pounds.

I think, just ballpark, 100 pounds of sugar will = 7 gallons of pure ethanol.

The yeast is cheap, like 50 cents per 7 gallons.

Looks like home brew is about $2 a gallon, not $1, but it is an interesting concept.

The real savings will be turning waste, sugary by-products of other things into ethanol.
Clean table sugar IS cheaper than gasoline, but only ~30% ? less?
Waste products are really cheap, or free!
( How about scraps from a bakery, or candy store??? )

One suggestion from the web site was to collect waste from bars and breweries.
How cheap can you get spoiled or out of date Budwiser? Sure, it's only 4 gallons of ethanol per 100, but it could be nearly free!
