Apparatus and methods to generate electricity from air and municipal sewage, manure, food waste and/or potentially other organic waste sources using sulfate reducing bacteria, SRB. The SRB produce hydrogen sulfide in an apparatus named a biominer. The odorous gas is then scrubbed into an aqueous solution. The solution is sent to an electrolytic continuous flow cell power generator on the anode side where the sulfur is oxidized to sulfate and is recycled to the biominer process. The generator cathode side uses a standard oxygen cell chemistry.
