An electrolytic reaction system for generating gaseous hydrogen and oxygen includes a reaction chamber for accommodating an electrolyte as well as an electrode arrangement, which is formed of anodic and cathodic electrodes. Between lateral surfaces of electrodes arranged to be spaced apart from one another, at least one flow channel for the electrolyte is formed, which extends between a first axial end for admitting the electrolyte into the electrode arrangement and a second axial end for discharging the electrolyte out of the electrode arrangement. The at least one flow channel has at least one first flow cross-section and at least one second flow cross-section, wherein the second flow cross-section has a smaller size than the first flow channel, and the comparatively smaller second flow cross-section is formed in a partial section of the at least one flow channel closest to the second axial end of the electrode arrangement.

This publication relates to a method and a system for producing freshwater through a reverse osmosis process in a submerged membrane system requiring a differential pressure over the membrane system. The differential pressure is provided by introducing gas bubbles in the riser device (2) downstream the outlet (7) for fresh water in the riser device (2). The system comprises at least one submerged, reverse osmosis unit (1), with an inlet (4) for water and an outlet (7) for fresh water, a riser device (2) extending from the outlet (7) of the submerged membrane system to at, above or below sea level and a system for providing a low pressure side for the reverse osmosis process.

Timing of HHO gas injection into a 4-stroke engine is optimized based on engine operating parameters to improve fuel economy.

A distributed hydrogen generating fence is formed from a plurality of electrolysis units and fence posts. Each unit includes one or more PV cells, an associated electrolysis system powered by electricity generated by the one or more PV cells, and a feed header for feeding water and an electrolyte to the electrolysis system. The electrolysis system is inside the feed header, and is operable to produce hydrogen and oxygen. The units are located between and are supported by mutually adjacent fence posts. The feed header extends in an inclined manner between the mutually adjacent fence posts. A gas header conducts at least the hydrogen from each of the plurality of units to a first remote facility. The fence includes openings allowing the passage of animals, people or vehicles. The openings can be controlled by a gate, or a grate laid across a hole in the ground spanning the opening.

The invention relates to a reactor which comprises a plurality of mutually parallel plates arranged spaced apart from each other, and adapted to be attached to a current source such that at least one of the plates is a cathode plate, at least one of the plates is an anode plate and at least one of the plates is a neutral plate and arranged between the cathode plate and the anode plate, and a plurality of frames, each of the frames of the plurality of frames being arranged for circumferentially enclosing a cavity adjacent to at least one the plates, and a conduit for supplying water and electrolyte into said cavities and a conduit for leading the liquid enriched with the produced gas formed in said cavities from the reactor, wherein the reactor further comprises at least one permanent magnet or a plurality of permanent magnets attached to the anode plate and to the neutral plates spaced apart from each other at that side of the anode plate which faces the cathode plate, the north sides of the permanent magnets facing the cathode plate.

The hydrogen production system for internal combustion engines includes an intake air scoop, a vacuum block having an air input port system for receiving air from the intake air scoop, a water reservoir connected to the vacuum block for providing water to be mixed with the air in the vacuum block, at least one primary generator assembly with an inlet port for receiving the air/water vapor mixture from the vacuum block and producing a mixture of hydrogen, produced oxygen, and fine hydrogen production vapor from a partially oxidized water fog, and a plurality of secondary hydrogen generator assemblies connected to the primary generator assembly for receiving this mixture. The engine vacuum draws this mixture into the intake manifold to provide an ideal fuel mixture for the engine.
