Apparatus for preparation and distillation of low-alcohol-content, fermentation products into high-alcohol-content, fuel-grade product using solar energy to carry out the fermentation and distillation. The apparatus includes a solar collector with reflectors, fermenting tanks, a distillation column, and temperature controls. The working fluid for the solar collector is isolated from the fluid being distilled.

A solar still for producing alcohol, comprised of: (a) at least one fermenting tank adapted to produce a beer by fermentation, (b) a heat exchanger, (c) a solar collector adapted to absorb energy from the sun and use that energy to heat a working fluid, (d) a working fluid conveying system adapted to circulate the working fluid through the solar collector and through the heat exchanger, (e) a distillation unit comprising: (1) a stripping fractioning column, (2) a rectification fractioning column, and (3) a transfer conduit operatively connecting the top of the stripping column to the bottom of the rectification column, (f) transferring means adapted to convey the beer from the fermenting tank to the heat exchanger, wherein energy from the working fluid is transferred to the beer, the beer and the working fluid flowing in separate conduits so that the beer and working fluid never mix, and (g) means for conveying the beer from the heat exchanger to the top of the stripping column where the beer is divided into an alcohol rich vapor phase stream which passes through the transfer conduit to the rectification column where it moves up the rectification column and an alcohol weak stream which flows downwardly through the stripping column, whereby beer in the vapor phase from the alcohol weak stream moves up the stripping column, through the transfer conduit to the bottom of the rectification column and up the rectification column.
