A system for processing saltwater or brackish water while recovering energy otherwise wasted in electricity generation by a natural gas generator or turbine. Heat in the generator exhaust is used to directly heat and process the water in the saltwater or brackish water into high quality steam, separating the majority of salt and contaminants from the water, and leaving potable water that can be permitted and released to the environment or sold for agricultural or industrial use such as oilfield activities. The system also captures and liquefies CO.sub.2 in the generator exhaust.

A solvent vapor supply apparatus for supplying solvent vapor to a substrate treatment apparatus, includes: a solvent storage which is kept warm at a temperature equal to or higher than a saturation temperature of a solvent stored therein; a precooler which precools the solvent vapor generated in the solvent storage; and a temperature regulator regulates a temperature of the precooled solvent vapor to a target temperature when the solvent vapor is supplied to the substrate treatment apparatus, wherein the temperature regulator supplies the solvent vapor regulated to the target temperature to the substrate treatment apparatus.

A water production system with a thermal separation device that defines a cold region and a hot region, a fluid-air heat exchanger located remotely from the thermal separation device and exposed to air, and a fluid circulation loop that thermally connects the cold region of the thermal separation device to the fluid-air heat exchanger so as to cool the fluid-air heat exchanger and condense water from ambient air to produce water pure enough so that with further treatment it can be made potable. Also disclosed are filtration and dispensing features that are appropriate for a potable water supply.
