Abstract: 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.

Abstract: Sample conditioning systems and methods especially useful for converting non-elemental forms of mercury to elemental form. The systems involve a reactor having a heater, with the reactor configured such that a heated sample is flowed through a calcareous sorbent during heating and then cooled in the presence of a solid metal that is more chemically active or less noble than mercury. The methods may be used as a part of an emissions monitoring process to insure compliance with emission standards and to precisely gage the amount of abatement needed.
