The present invention provides a pump device comprising a housing and a electrode device. The housing has an inlet and an outlet arranged at a side of the housing for allowing a first flow flowing into the housing. The electrode device is arranged in the housing, and comprises a rotating body having a fluid inlet, a plurality of first flow channels, at least one first electrode and at least one second electrode. The rotating body is driven to rotate thereby generating a negative pressure for drawing the first fluid into the plurality of first flow channels through the fluid inlet such that the first fluid is reacted with the first and second electrodes thereby generating micro bubbles and is exhausted from the plurality of first flow channels. The first flow having micro bubbles are exhausted from the housing through the outlet.

A floor scrubbing apparatus includes a reservoir for an aqueous salt solution disposed in the floor scrubbing apparatus. An immersion device comprising a submersible housing with at least two iridium-coated electrodes spaced apart from each other within the submersible housing is adapted to be immersed into the reservoir. The floor scrubbing apparatus also includes a control module electrically coupled to the electrodes, wherein the control module controls application of electricity to cause a first electrode to be positively charged and a second electrode to be negatively charged.

A method for producing one or more hydroxide solids includes providing a catholyte comprising an electrolyte solution; contacting the catholyte with an electroactive mesh cathode to electrolytically generate hydroxide ions, thereby precipitating the one or more hydroxide solid(s); and removing the one or more hydroxide solids from the surface of the mesh where they may deposit.

A system and method for generating arsine are disclosed. The system may include a shell having a top interior surface. The system may also include a cathode-anode assembly positioned in the shell and forming an elongated structure substantially parallel to the top surface. The cathode-anode assembly may include a first electrode and a second electrode surrounding the first electrode and forming a gap therebetween. The second electrode may include a plurality of channels along a length of the second electrode. The plurality of channels may allow circulation of electrolyte within and around at least a portion of the cathode-anode assembly and allow gases generated in response to current applied to the cathode-anode assembly to escape from the cathode-anode assembly. Such gases may be used as precursor gases for a high-volume metal-organic chemical vapor deposition (MOCVD) operation.

Disclosed is an electrochemical process to simultaneously produce a syngas suitable for the Fischer-Tropsch (F-T) process and oxygen. In an example embodiment, the process includes feeding steam and CO.sub.2 to an intermediate temperature (e.g., <700 C.) electrochemical reactor to produce separate CO-rich and O.sub.2-rich streams. An additional electrochemical reactor can be used to produce H.sub.2. The H.sub.2 is combined with CO from the first reactor to produce a syngas mixture ideal for a downstream F-T process. Alternatively, the electrochemical reactor can produce methane directly or a methanol stream for conversion to a hydrocarbon fuel.

An improved, gaseous electrolysis apparatus can include a cooled header for electric connections or couplings, an exemplary co-disposed, coaxial heat exchanger around the reaction chamber to extract heat from the reaction chamber and exemplary rugged gas source and collection manifold(s) to support fixed and/or mobile applications in an embodiment. The system can include a heated anode and co-disposed cylindrical cathode within the reaction chamber and an improved electronic control circuit in an embodiment.

An energy conversion system includes a water-containing vessel with a transparent sidewall. Energized carbon rods are fed into the vessel such that the carbon rods are immersed in the water. The carbon rods are juxtaposed sufficiently that electrical arcing occurs between them, causing decomposition of some water molecules into constituent hydrogen and oxygen gas. Photon emissions resulting from the arcing are collected by photovoltaic cells placed around the sidewall of the vessel. The hydrogen gas is cooled by passing it through a water reservoir which also provides a source for water in the vessel. The cooled hydrogen gas may be used to fuel an internal combustion engine. Byproduct heat from the arcing reaction may be utilized in a Stirling engine or radiated from the system. As the carbon rods become depleted during arcing, additional rods are fed through conductive sleeves into the vessel by linear actuators.
