Potable water is produced by extraction of water vapor from air. Water absorbed inside a desiccant bed is forced into vapor phase by using input heat energy, for example, waste heat from the exhaust of an internal combustion engine. Pre-heating a portion of the desiccant material prior to desorption enhances efficiency. Energy for the pre-heating may be obtained by recovering heat from the desiccant material prior to adsorption.

Method and apparatus for generating water using an energy conversion device

A fluid treatment system incorporating an integrated heat exchanger and thermal treatment unit. A fan draws or pushes a contaminated fluid through the heat exchanger, which is preferably of the counter flow type. The integrated heat exchanger and thermal treatment unit is fabricated by stacking sheets of metal foil so that gaps are defined between adjacent sheets. These gaps define alternating untreated and treated fluid channels. The untreated fluid flows through the heat exchanger and into the thermal treatment unit, with is disposed within aligned orifices formed in the metal foil sheets. Heat transfer occurs between adjacent treated and untreated channels, which greatly improves the efficiency with which a temperature of the untreated fluid entering the heat exchanger is changed as a result of heat transfer with the treated fluid that is exiting the heat exchanger. A header system is in fluid communication with either all of the treated or all of the untreated fluid channels. The integrated heat exchanger and thermal treatment unit also usable as a chemical reactor to generate a desired chemical product from at least one reactant.

Integral compact heat exchanger and catalytic reactor for scavenging contaminants from air

A portable modular water heater system having a heat exchanger and a fluid heating channel for heating water from a reservoir and for optionally producing purified potable water. Optionally, a thermoelectric module is included in the system for producing an electric current usable to rechargeable batteries, drive pumps, or other devices. When the heat exchanger module is exposed to a heat source, heat absorbed by the heat exchanger is transferred to the fluid heating channel, heating the water. The heated water is forced into an upper portion of the reservoir. A condenser module is optionally coupled to the reservoir to condense steam in the upper portion. The thermoelectric module produces an electrical current when exposed to a temperature differential between the reservoir's cool water and the heat exchanger. A portable microclimate heating system, such as a jacket with tubing, can be heated with the heater system.

Modular water heater

A method and apparatus for purifying water by using thermal and/or thermocatalytic processes. The method and apparatus are particularly useful for processing impure water to remove and/or deactivate toxic inorganic, organic, and/or biological species such as Sarin, mustard gas, phosgene, cyanogen chloride, anthrax, , Giardia cysts, salmonella, hepatitis, and Norwalk viruses. In the thermal process, contaminated water is heated (preferably superheated) forming steam, whereby a majority of inorganic and biological species are removed or deactivated from the water. The steam is then condensed, forming liquid purified water. In the thermocatalytic process, the steam is brought into contact with a hydrolysis catalyst, preferably in the form of a coated surface or replaceable catalyst element. The hydrolysis catalyst, which may be a metal oxide, thermocatalytically deactivates at least 90% of the organic or biological species in the water, converting them to less toxic organic species or non-viable biological species. Various embodiments of the apparatus are provided, including portable configurations. Each of the embodiments include at least one boiler, at least one condenser, and a water reservoir arranged in heat exchange relationship so as to improve an overall operating efficiency of the apparatus. The apparatus is heated using a portable stove or other heat source, and a counterflow heat exchanger preheats water that is to be vaporized and cools the purified liquid water formed in a condenser.

Method and apparatus for water purification

A method and apparatus for purifying air to deactivate toxic chemical and biological species such as Sarin, mustard gas, phosgene, cyanogen chloride, Anthrax spores, bacteria, Salmonella bacteria, Hepatitis virus, and Norwalk virus. The apparatus comprises a reaction chamber coupled to a counterflow heat exchanger. Incoming contaminated air is directed through a heating side of a counterflow heat exchanger to preheat it. The air is further heated to a temperature of at least 200&deg; C., which is sufficient to deactivate common biological toxic species. Optionally, the reaction chamber may include a catalyst on a surface area over which the heated air is directed, which enables a thermocatalytic reaction that is particularly effective in deactivating biological and chemical warfare agents, such as anthrax and Sarin. Portable embodiments of the invention are useful in both military and civilian air purifying applications, while fixed installation of the apparatus are useful in deactivating toxic species from the air in areas where food is prepared or stored, or in purifying air in the environment of a living space.
