A disclosed desalination system includes an HDH system including a humidifier and a dehumidifier that, together, are configured to process a first saline fluid to produce freshwater in the dehumidifier. The desalination system also includes an AD system operatively coupled to the HDH system. The AD system includes a first bed, a second bed, an evaporator, and a condenser that, together, are configured to process a second saline fluid to produce freshwater in the condenser. The condenser is configured to transfer heat exhausted by the first or second bed from a vapor, obtained from the second saline fluid, to air circulating through the humidifier and the dehumidifier to drive the HDH system. The evaporator is configured to provide a cooling effect.

Disclosed herein is a system and method for condensing moisture in a gas stream entering or leaving a bioreactor, the system comprising: a contact condenser container fluidically coupled to the bioreactor through an exhaust line; a condensate accumulator fluidically coupled to the contact condenser container through at least a first condensate line and a second condensate line; the condensate accumulator further fluidically coupled to the bioreactor through a condensate overflow line; a first condensate control device disposed on the first condensate line and configured to control a flow of condensate leaving the contact condenser container and entering the condensate accumulator; and a second condensate control device disposed on the second condensate line and configured to control a flow of condensate leaving the condensate accumulator to be mixed with the gas stream.

An atmospheric water generation system comprises water vapor consolidation systems configured to increase the relative humidity of a controlled air stream prior to condensing water from the controlled air stream. The water vapor consolidation system comprises a fluid-desiccant flow system configured to decrease the temperature of the desiccant to encourage water vapor to be absorbed by the desiccant from an atmospheric air flow. The desiccant flow is then heated to encourage water vapor evaporation from the desiccant flow into a controlled air stream that circulates within the system. The humidity of the controlled air stream is thereby increased above the relative humidity of the atmospheric air to facilitate condensation of the water vapor into usable liquid water.

A method and system for condensing water for injection into an internal combustion engine to increase the engine's fuel economy and performance while reducing emissions. A volume of ambient air is drawn through an intake valve into a sealable chamber. The intake valve is closed and the ambient air compressed within the sealed sealable chamber and thereafter vented through an exit valve to be contained in a cooling section. The cooling section comprises a port and a cooling device. The cooling device, which in one embodiment comprises a refrigeration unit, cools the ambient air contained within the cooling channel to condense water vapor present in the ambient air into liquid water. The liquid water is drained from the cooling channel through the port and collected in a reservoir. Liquid water from the reservoir is then injected into at least one combustion chamber of the internal combustion engine.

A drying apparatus includes a body and a rotatable foot pad located on the lower part of the body to dry a user's feet. An air inlet is provided, and a flow generator to receive inlet air from the air inlet and generate an airflow to the top surface of the foot pad.

The water-dispensing method for furniture incorporates a water recovery process, a water STT process, and a discharge process. The water recovery process: a) converts water contained in a gas phase in the atmosphere into water in a liquid phase; b) initially treats the converted liquid phase water to remove microorganisms and other chemical contaminations; and c) transports the initially treated liquid phase water to the water STT process. The water STT process: a) receives and stores the initially treated (liquid phase) water from the water recovery process; b) subsequently treats the stored water with a final treatment to remove microorganisms and other chemical contaminations; and, c) transports the treated stored water to the discharge process. The discharge process: a) receives the water from the water STT process after the final treatment; and, b) controls the discharge of the water received from the water STT process.

A drying apparatus for use in drying of a person's body by a forced airflow includes a body, a bar supported by and movable relative to the body, an air inlet to receive surrounding air into the body as inlet air, an air outlet, and a convolute portion at an air inlet flow path to capture liquid received in the inlet air.
