Someonelse42 Posted February 3, 2015 Report Share Posted February 3, 2015 I have searched the growing forums about this and it seems no one knows really how it works.I found some info about how much co2 is produced by yeast, and found some awesome yeasts at the homebrew shop. Basically you get about 1/2 co2 for every 1 of sugar fermented under ideal conditions. This means that with startup, and finishing not being ideal, you get about 1/3 co2 per 1 of sugar. For example, 3 kilos of sugar makes about 1 kilo of co2. Wow, huh? i bet you didnt think it was that much, and if you want huge amounts you can get "turbo yeast" which will convert 6 kilos of sugar in 24 hours.Thats 2 kilos of co2 in 24 hours! And the drum will be about 20% alcohol. Got a still? Now i know if you shop around you can get a good price on co2 refills, but most of us will be paying about $4 a kilo. I can get a kilo from sugar for less than $3, thats 3 kilos of sugar, and a bit of yeast to make one kilo of co2.And theres no huge cost to start, like a bottle and regulator, you can just use a 20L bucket with a lid, and get a 50 cent airlock from the brew shop. Dont bother with a soft drink bottle and baking yeast fermenting a couple of tablespoons of sugar, its a joke. Using turbo yeast is good value. You can control the speed of fermentation by adding different amounts of yeast. So you could put say.. 3 kilos of sugar, but only a little yeast, means it will last for 4 or 5 days, a nice supplement for a room that doesnt get ideal ventilation. Designed to make a wash for distilling spirits, it can handle high alcohol, ensuring all the sugar is converted. So if you have a spare $20 this weekend, you could make those ladies fat enough to fall over. What i found that is actual scientific fact and not just what some guy thinks: C6H12O6 = 2 C2H5OH + 2 CO2 So 1 mole of sugar yields 2 moles of ethanol and 2 moles of CO2. The MW of sugar is 180 (6 x 12 + 12 x 1 + 6 x 16) and the MW of CO2 is 44 (1 x 12 + 2 x 16). Therefore, 180 grams of sugar yields 2 x 44 or 88 gms of CO2. Thanks to Google.
