Abstract:
1. A process for producing butanol from common algae, ubiquitous bacteria, water, sunlight and carbon dioxide consisting essentially of the following steps: a. collecting aerial algae spores and soil bacteria; b. culturing said algae in water in clear tanks exposed to sunlight by pressurizing said tanks with carbon dioxide and placing said pressurized tanks in sunlight; c. agitating the tanks; d. harvesting said cultured algae by skimming the top 3 inches of the culture; e. transferring the skimmed portion to a tank for fermentation, wherein the tank comprises bacteria of the genus f. placing the fermented culture in an underground tank to cool the contents thereof to an earth temperature of 10° C. and then subjecting the cooled culture to chilling at 0° without freezing to effect separation of butanol from the chilled culture; and g. decanting the butanol that has risen to the top of the tank.
