Lol, probably if you hooked it up to a turbine or something (though I doubt you could power all that much from it!).\n\nOf course, the water board would come round and have a word with you if you were using water constantly...\n\nAs Answers has a 'no chatting' policy I can't actually ask you questions, so I'll assume that you are living at your parents or something hence the free water.  Or maybe you are on a fixed bill.\n\nFor the former your parents will kill you, for the later the water board will kill you.

see the diagrams in the source\n\nBig Idea\nWater is comprised of two elements - hydrogen (H) and oxygen (O). Distilled water is pure and free of salts; thus it is a very poor conductor of electricity. By adding ordinary table salt (NaCl) to distilled water, it comes an electrolyte solution, able to conduct electricity.\n\nKey Concepts\n\n    * Ionic compounds such as salt water, conduct electricity when they dissolve in water.\n    * Ionic compounds consist of two or more ions that are held together by electrical attraction. One of the ions has a positive charge (called a cation) and the other has a negative charge (anion).\n    * Molecular compounds, such as water, are made of individual molecules that are bound together by shared electrons (i.e. covalent bonds).\n\nEssential Questions\n\n    * What happens to salt when it is dissolved in water?\n    * What are electrolytes?\n    * How can we determine the volume of dissolved ions in a water sample?\n    * How are atoms held together in an element?\n\nKnowledge and Skills\n\n    * Conduct an experiment to see that water can be split into its constituent ions through the process of electrolysis.\n    * Prepare and experiment with a 10% salt solution to better understand the process of ion exchange.\n    * Discuss and research the "softness" and "hardness" of water.\n    * Use the periodic table to identify elements and learn their characteristics.\n\nPrior Knowledge\n\n    * Define the difference between ionic and molecular compounds.\n    * Salt consists of sodium (Na) and chloride (Cl).\n    * Water is a tiny, V-shaped molecult with the molecular formula H2O.\n    * A basic understanding of how a battery works.\n    * Atoms are made of a positive nucleus surrounded by negative electrons.\n    * An atom's electron configuration, particularly the outermost electrons, determines how the atom can interact with other atoms.\n    * All matter is made up of atoms.\n    * Atoms of any element are alike, but different from atoms of other elements.\n\nCommon Preconceptions\n\n    * Students may think - "Water is a good conductor of electricity." Water is a very poor "conductor" of electricity. (The ionization constant for water is very small.) The reason it is dangerous to insert a light bulb while standing in a puddle of water is that water is a great solvent for ionic compounds. Tap water and fresh water typically contain dissolved ions in sufficient concentrations to enable the solution to be conductive. However, ions in solution carry the charge and are therefore responsible for the current, not the water itself.\n    * Students may think - "Electrons can flow through solutions." In "conduction of electricity" through solutions, electrons themselves do not pass through the solutions. Rather, the charge balance is maintained in the solution by movement of cations and anions toward the electrodes where charge transfer takes place at the solution interface.\n      Water is comprised of two elements - hydrogen (H) and oxygen (O). Distilled water is pure and free of salts; thus it is a very poor conductor of electricity. By adding ordinary table salt (NaCl) to distilled water, it comes an electrolyte solution, able to conduct electricity.\n\nConcept Map\nThis lesson and activity relates to the branch "Phases of Water" from the comprehensive Aquarius Concept Map - Water & its patterns on Earth's surface.\n\nBackground\nIn chemistry, electrolysis is a method of separating bonded elements and compounds by passing an electric current through them. An ionic compound, in this case salt, is dissolved with an appropriate solvent, such as water, so that its ions are available in the liquid. An electrical current is applied between a pair of inert electrodes immersed in the liquid. The negatively charged electrode is called the cathode, and th positively charged one the anode. Each electrode attracts ions which are of

yes it is possible to have that removed from your water by reverse osmosis.\nI dont know how you can stand the taste of your water.\nYea, that sounds bad to me also.  Get yourself a good filter (not the cheap kind) for your sink, it's cheaper in the long run than bottled water.  Get the filter which filters down to the smallest micron and that's about all you can do.  Best Wishes!

You'll have to explain what you mean by solar hydrogen panels. \n\nThe most common is through steam reforming which must be done on an industrial scale. Steam reforming uses separates hydrogen from the carbon components in methane and methanol on catalytic surfaces. Something that would be impossible outside a very advanced lab or factory.\n\nThe second most common method of extracting hydrogen from water is through electrolysis where voltage is applied to water.  You can make some at home quite easily and safely. You just need a 9V battery, some wire, and the cleanest water you can find.\n\nYou simply place the two wires in the water while connected to the battery and hydrogen bubbles start forming. Use salt to make it more efficient.\n\nSee this site for more info.\nhttp://www.theodoregray.com/PeriodicTable/Stories/001.1/

That's a big no.  The same chemical properties that make it so oil and water don't mix makes it so oil cannot conduct electricity...ever!  In fact, to make it do so you'd have to change it's composition so completely it wouldn't really be oil anymore! :-P

Distill the water. The WATER comes out of the tubes, not the salt.\n    As for testing, just drink a little of it. Do you *LIKE* it?\nNo? Well you better make sure that you don't put it back in the same cup you used for collection.\nOK the water will still pass an electric current through it if it has any impurities. Completely pure water will not.\nUnless you use more than around one volt, in which case the bubbles you see escaping will be hydrogen and oxygen. That means you've gone too far with the testing part.

1. VERY PURE water is a poor conductor of electricity. However, very small \namounts of impurities, especially salts, greatly increase the electrical\nconductivity of water.\n2. The main carriers of electrical current are dissolved ions. If a \nbattery is connected to a container of water so that\nthe (+) and (-) poles of the battery are immersed in the water, the\npositive ions will migrate toward the (-) pole and the negative ions will\nmigrate toward the (+) pole (electrical opposites attract). This closes the\n"switch" and electric current flows through the solution.\n3. Different ions can help carry the electric current, some more / some \nless, depending upon their electrical charge and their size. More highly charged, \nsmaller ions are more efficient carriers of the electrical current.\n4. The higher the concentration of ions, the greater is the conductance of \nthe solution.\n5. There is a complication however, the water and / or certain of the ions \nmay undergo a chemical reaction to one or the other, or both of the electrodes.\nYou may not want to introduce this in the beginning but it does happen.\n6. None of the ion electrical current carriers of salts dissolved in water \nare as mobile as "free" electrons in a metal are. And the differences are very\nlarge. For example, if the conductivity of  VERY PURE WATER is 0.000004\nconductivity units, the conductivity of a saturated solution of common\ntable salt NaCl is 23 conductivity units, and the conductivity of a typical\nmetal such as copper wire is 60, 000, 000 conductivity units. So while the\nions in a dissolved salt behave something like "free" electrons, they are\nvery slow and sluggish moving. \nCompletely demineralized water actually does not conduct electricity, and is\nwidely used as a coolant in high powered radio amplifiers.  However, when\nexposed to even small amounts of impurities, (even normal air), It becomes a\nfair conductor.  It is not the water conducting this electricity so much as\nthe dissolved minerals in it.  Some of these minerals are decent insulators\nthemselves, but when dissolved in water still allow conduction because the\nmolecules are now free to move around.\nIn ionic liquids these electrons remain \nstuck to big, round atoms,\nand these atoms do the swimming around, relatively slowly, dragged by \ntheir electric charge.\nSort of a ball and chain thing.\nElectrons in metal are "free"; they slip rather freely across all the \natoms, and do not need to drag one around with them.\nSo, carrier mobilities in ionic liquids are some orders of magnitude lower \nthan carrier mobilities in metals.\nSo their resistance is higher.\nIf you had a snail-trail of salt-water or molten salt with the same length \nand cross-section as a metal wire,\nit would use up half the voltage and get hot trying to pass one tenth the \ncurrent the wire can handle.\nIn a metal, each metal atom contributes about one mobile electron that \nhelps the current flow.\nIn molten salts like NaCl, every atom has a + or - charge and contributes \nto the current flow.\nSo there are just as many carriers per unit volume as in a metal.\nBut in water-solutions of salts, the salt is a minority.\nUsually less than 10%  of the solution is ions, so that makes the \nconductivity even poorer.\nThat is part of why we will never make our power lines out of seawater in \npipes.

water is generated by combining Hydrogen and Oxygen in a retort and applying eletrical spark.\nCoolant and pharmaceuticals labs

Of course dude!! The water tastes cleaner with that. \nFeels like your drinkin' bottled water everyday..

We could... \n\nIF you took a maser  (a laser but insteat of  light it is microwaves) or some other microwave generator and focused the beam on a bucket of water It would heat up the water, and act as a radiator.  \n\nMany radiators work on the priciple of heating up and cirulating water... IT is just that most use a electric heat source to heat the water.  \n\nBut there are some problems.  \n\nFirst ... What if someone or something were to get in the way of this microwave ray... They could get seriosly burned... as well it might be able to cause cancer.  \n\nSecond... IF mircowaves are shown on to a peice of metal instead of heating up the metal it causes a charge to be formed. If the microwave ray hit any metal It would shock who ever was wearing it, or destroy any electronics. (thus you would have to have a plastic radiator as well)  \n\nLast...\n\nThough it is a good idea, and I think it could work... It will be very expencive.  A mircowave used for heating is less that 20% efficent... A maser is less that 5% efficent.  This method will cossume ALOT of electricity.  \n\nBut it is a good idea... IF electricity was cheaper It might be very fesible.

Moving water as in a river or water tuned to steam can turn a turbine and produce electricity.  http://en.wikipedia.org/wiki/Turbine

Some tips...\n--Use a strong electrolyte (substances that will break up into ions [almost] completely in solution), the higher the concentration, the better.  Also you need to be careful on which electrolyte you choose.\n--Try not to use an over volttage (a voltage over the minimum necesary to electrolisize the water.  Insread, try to use a very high current, higher current = more production of gasses.  To increase current without increasing voltage, reduce resistance.\n--Place the electrodes close together to reduce internal resistance in the cell.\n\nEven by doing these things, you cannot hope to get much better than about 50% efficency doing water electrolysis, maybe 65% if you are good.\n\nThere are yahoo groups out there devoted to just such a tast as Hydrogen production through water electrolysis (I have one infact), they can also give advice based on experience.

Yes , it is. And this from at least two view points:\n1) The salty marine water is a full of ions, so it represents  very clearly a electrolyte which is a conductive solution. All you need then is some electrodes which should have some differential potential in electronegativity. \n\n2)  The power of the waves which, there are already used as one of the alternative power producing  method. This is used either by actuating some radial turbines, or indirectly some kind of pistons actuated by some floating devices found on the surface of the water, in relative axial motion with respect to the fixed body of the piston. All of this devices are using the power of waves to actuate, then  directly, the generators. \n\nGood luck \nDfriend :)

Do you mean demineralized water?\n\nReverse osmosis is the most economical way.\n\nCheck out millipore, look up their RO products.

Get an electrical heating element, a DC power supply, a thermometer, a voltmeter and an ammeter.\nPass electricity through the heating element, dipped into a measured volume of water (or salt water) in an insulated cup, and measure the current, the voltage and the time taken. This will give you the heat energy supplied. Measure the temperature rise, and work out how much energy would be required to raise 1g of water (or salt water) by 1 degree Celcius. The answer should be close to 4.2!

In an electrolytic cell you can plate most any metal that doesn't quickly react with the solvent and its solutes.  The force of the copper ions gaining electrons at a negative charged zinc electrode is certainly possible.\n\nSince the copper would receive two electrons and go from a +2 to a zero oxidation state, you would say that it is being reduced.
