A method and system for cost-effectively converting a feedstock using thermal plasma, or other styles of gassifiers, into an energy transfer system using a blended syngas. The feedstock is any organic material or fossil fuel to generate a syngas. The syngas is blended with any fuel of a higher thermal content (BTU) level, such as natural gas. The blended syngas high thermal content fuel can be used in any energy transfer device such as a boiler for simple cycle Rankine systems, an internal combustion engine generator, or a combined cycle turbine generator system. The quality of the high thermal content fuel is monitored using a thermal content monitoring feedback system and a quenching arrangement.

A method of recovering lithium from an aqueous source is described. Lithium is extracted from the aqueous source using a sorption/desorption process to form a lithium extract. Impurities are removed from the lithium extract to form a purified lithium extract, and the purified lithium extract is concentrated using a water removal process to form a lithium concentrate. The lithium concentrate is then converted to one or more of lithium carbonate and lithium hydroxide to form a converted stream. Various streams, including some lithium-containing streams, are recycled to the sorption/desorption process.
