A method and apparatus for treating residuals or waste streams from a plant, such as a drinking water treatment plant. The method includes the steps of obtaining plant residuals or waste streams from a water treatment plant and irradiating the plant residuals or waste streams using microwave radiation from a microwave source. The method also includes the step of drying the plant residuals or waste streams to a predetermined moisture, volume, or weight content reduction and disposing of the same.

A multi-cavity microwave cooking appliance provides at least two (2) microwave cooking ovens a vertically elongated third beverage heating unit in at least one (1) embodiment. In general, each of the ovens and the heating unit are operated and controlled independently from each other. However, the ovens and heating unit may be controlled together if a particular switch is pressed. Each oven and the heating unit have separate access doors, magnetrons, and control switches. A control unit can be used to enter cooking information to the ovens and heating unit. The multi-cavity microwave cooking appliance further supports a tray and turntables.

A heating system includes: a microwave generator; a medium reservoir chamber; a radiator; and a channel that fluidically connects the medium reservoir chamber and the radiator. The radiator includes hollow fins extending from and in fluidic communication with the channel. A medium extends as a single fluid body within a combination of the medium reservoir chamber and the channel. The microwave generator is configured to generate microwaves directed into the medium reservoir chamber so that the microwaves impinge upon internal surfaces of the medium reservoir chamber to thereby impinge upon the medium within the medium reservoir chamber, causing the medium to be heated, the heating of the medium generating a hot vapor in the channel, which rises from the channel into the fins, the fins thereby being heated for radiation of heat into an external environment.

The claimed invention provides an eco-friendly alternative to traditional gas boilers, specifically the claimed invention provides a boiler that uses microwaves as a means to heat water within a boiler system. Preferably the water enters the boiler via one or more spray nozzles to produce a plurality of droplets or mist, which is then heated when they are exposed to the generated microwaves within the boiler.

A zero-carbon footprint heating system for a fluid and conditioned air uses electromagnetic energy created by one or more magnetrons operated by high voltage transformers. The heating system includes nested fluid filled conduits in communication with the magnetrons for heating of the fluid. The heated fluid passes through a heat exchanger for heat transfer to the air being conditioned by the system.

A method and an apparatus are provided for on-demand and instant warm water supplying at the point of consumption. In this method only cold water is distributed and supplied to different places within a building through a single piping system. The apparatus has only a single input pipe for cold water and heats water in a heating unit just as needed on demand at the point of consumption after harvesting the heat energy of wastewater from drainage. The heating unit alternatives are an electric resistive element, a magnetron generating microwave, or a thermoelectric body warming the input water as needed and no more through a controller. No hot and cold-water mixer is used. The method and apparatus help the building industry save on plumbing costs and consumed energy and water, while bringing more comfort to users through direct and local discharging of warm water on demand and as adjusted instantly.

An enhanced flash chamber with a flash chamber; a microwave source in communication with the flash chamber for providing a quantity of energy to a plurality of antennas within the flash chamber; a fluid chamber positionable within the flash chamber capable of holding a liquid and the plurality of antennas; and transport tubing for transporting a target material for extraction through the fluid chamber where the quantity of energy from the microwave source interacts with the plurality of antennas to heat the liquid held in the fluid chamber to a superheated state and the superheated state of the liquid transfers a portion of the quantity of energy to the target material to extract an extraction product from the target material.

A heater wire including at least one extending component disposed thereon. The heater wire is positioned within a respiratory gas conduit. The heater wire may include a wire component and a groove that extends along a length of the heater wire. The heater wire may also include threads extending from an outer surface of the heater wire that faces away from the wire component. The threads may be woven or braided threads.
