Electrical power Electrically accelerated water

Stray-current Corrosion. Stray currents in the past have resulted from DC-powered trolled systems, which have become obsolete. An electric welding machine on board a ship with a grounded DC line located on shore will cause accelerated attack of the ship s hull as the stray currents generated at the welding electrodes pass out of the ship s hull through the water back to the shore. Houses in close proximity can dramatically corrode at the waterline. The pipes in one house can be completely corroded, while those in the neighboring house may be intact. 

Fig. 7.4. The proton beam strikes the lead target generating neutrons which are moderated in the surrounding heavy water blanket. Molten salt carrying fissile material for heat generation and electric power production circulates in the heavy water blanket through double-walled pipes. Some of this power drives the accelerator. Nuclear waste including that produced in the molten salt is also circulated through the blanket in a separate loop and transmuted to stable and short-lived nuclides which are extracted and...

There is also a heating effect due to ionic conduction, since the ions (sodium, chloride, and hydroxyl) in the water inside materials are accelerated and decelerated by the changing electric field. The collisions which occur as a result of the rapid accelerations and decelerations lead to an increase in the random kinetic (thermal) energy of the material. This type of heating is not significantly dependent on either temperature or frequency, and the power developed per unit volume P from this mechanism is... 

Considerations similar to those presented above show that illumination of a semiconductor leads to a shift of both the Fermi level and the quasi-levels of holes and electrons, and both the forward and reverse reactions, proceeding according to Eq. (1), are accelerated. In other words, the result of illumination is, above all, the efficient increase of the exchange current in the redox couple but this is not the only result. If a semiconductor under illumination is an electrode in an electrochemical cell and is connected through a load resistor with an auxiliary electrode, the cathodic and anodic reactions become spatially separated, as in the case of water photoelectrolysis (Fig. 11) considered above. The reaction with the minority carriers involved proceeds on the semiconductor surface, and that with the majority carriers involved, on the auxiliary electrode. Thus, the illumination of a semiconductor electrode gives rise to an electric current in the external circuit, so that some power can be drawn from the load resistor. In other words, the energy of light is converted into electricity. This is the way a photoelectrochemical cell, called the liquid junction solar cell, operates. 

Hydrolysis can be brought about by water alone, if sufficient time is allowed, but as the process is extremely slow, it is customary in practice to accelerate the reaction by the use of various methods, which include (i.) the application of heat or electricity, (ii.) action of enzymes, and (iii.) treatment with chemicals the accelerating effect of the two latter methods is due to their emulsifying power. 

Fig. 7. A representative pulse power machine used for inertial confinement fusion is the Sandia National Laboratory Particle Beam Fusion Accelerator which consists of a slowly charged primary energy storage Marx capacitor bank under insulating oil, a water dielectric intermediate energy store capacitor, a switched pulse forming line which compresses the waveform in time, and a magnetically insulated transmission line which delivers the power pulse to a vacuum diode to produce energetic electrons or light ions, which are accelerated and focussed by electric and magnetic fields onto a target.
