Run a current through water and its molecules will split up at the electrodes forming Hydrogen and Oxygen (H20 => H2 + O2 requiring 854KJ/Mol). The process is not 100% efficient, as it involves the movement of molecules and ions to and from the electrodes, causing them to bump into one another on their way and hence increasing overall enthalpy. In fact, a high enough current will heat a small water bath to the point of boiling during a very brief period of electrolysis. However, this only happens because water in its natural form contains mineral salts which make it conductive. In its purest form (only obtainable through extensive de-gassing, purification and de-ionization), water is in fact a phenomenal dielectric, with a dielectric constant (K) of 802] and a voltage standoff in the order of several thousand volts per millimeter (this varies enormously with purity and somewhat with temperature). Because it behaves as a near-infinite resistance load for any source of EMF, ultrapure water, as is called the liquid having less than 10^12ohms/m resistance is used in some pulse forming network capacitors and for insulating some special high voltage high frequency lines and the like.Water being atomised.However, once the maximum voltage standoff for water is exceeded and the dielectric effect breaks down, something strange happens: The discharge stops being electrolytic (as molecules can no longer move to the electrodes at the rate dictated by the current) and the resistance plummets all at once, allowing massive currents to pass through it. When that occurs a bright flash of light is observed and some of the water in the sample is atomized (atomization here is used to describe a change from the liquid to the gaseous state that does not involve heating, such as in ultrasonic water atomisers) following a very loud report and a powerful shock wave traveling through the liquid.What makes this effect all the more strange is the fact that if one takes into account the heat capacity of the water in the sample, and compares it with the energy delivered, it becomes clear that the liquid temperature could not have risen by more than a few degrees centigrade, let alone the several thousand degrees required to obtain the pressures necessary for the kind of explosion observed. Over the years, several scientists and researchers have attempted to explain the phenomena, using everything from cold fusion to electrolysis and subsequent water reformation. Most of these theories are obviously flawed and were quickly refuted by mathematical proofs, whilst others are still being contemplated as potential (partial?) explanations for what is happening, and may need experimental evidence to be disproved.
This is from a very credible, independence engineering student, reporting from his own experience.
What makes him so credible?One of the first things i saw on the page was a "donate" button. Yeah, real credible.
Credit crunch everywhere eh?
