Abstract
An apparatus for manufacture of combustible gas consisting principally of methane with minor amounts of carbon monoxide, carbon dioxide and hydrogen from organic wastes comprising an inverted vessel positioned in a body of water in a matter of such that the water acts as a "liquid door" to trap plant material and gas within the vessel. The combustible gas manufacturing method provided by the apparatus operates at a temperature of about 21.degree. C. to 37.8.degree. C. Under ideal conditions it is possible to produce as much as about 11 cubic foot of gas per pound of organic waste. A moving current of water agitates the organic material and sweeps the waste products from the bottom of the vessel where they may be recovered and used as fertilizer if desired.
