Researchers from TU Graz and the Wetsus research center in The Netherlands have produced electrically charged water by means of a floating water bridge. The electric charge of the "water battery" can be stored for a short time.
The water bridges act as electrochemical or biochemical reactors, opening up a variety of possible industrial applications. Substances can be brought into contact with other materials in the water bridge for the purpose of chemical reactions.
Because acids and alkalis can also be produced without any opposing ions, new eco-friendly cleaning agents, waste-reduction methods, and medical applications are possible.
The water is protonically -- not electronically -- charged. The novel kind of water is either positively or negatively charged depending on whether it contains more or fewer protons.
Since the protons move at a finite speed, there is always an excess of protons in one water container and a lack of protons in the other. If the water bridge is suddenly switched off, the proton charges remain, as can be measured by means of impedance spectroscopy. The first investigations have shown that the fluid’s charge remains stable for one week.
