linekill 1 Report post Posted August 9, 2010 Oh my. Misinformation. Water will never be able to power a car nor is it any good when used in a hybrid engine unless you can create a super-machine that could violate the first and second law of thermodynamics. Electrolysis is required to break water apart into Hydrogen and Oxygen. So-called "Water-Fueled Cars" claims to be able to break water into hydrogen and oxygen. These produces are then allowed to react (Boom!) and energy is released for piston engines to move. Step 1: Dissociate Water into Hydrogen and Oxygen by applying electrical energy (electrolysis).Step 2: Allow the dissociated Hydrogen and Oxygen to react again to release energy. The problem is this: The energy required to break it into Hydrogen and Oxygen (Step 1) is the same as the energy that will be produced during the reaction between the produced water and release energy (Step 2). If such engine/machine is or has been created, good news! We now have a machine that can cycle an energy without losing any of it. Still, it's useless because it's just like using Steps 1 and 2 as a way to transfer energy or to play with energy not use it. But such machine will never be available for the next 100 years or so. And even if it's available, we still have no use of it other than mess with the energy. Another problem arises, there isn't 100% water. All contains particulate matter, some dissolved substances, etc. This means that more energy may be used to break water into hydrogen and oxygen. The energy released in step 2 will be exactly (or almost exactly) the same as the energy used to break water into hydrogen and oxygen WITHOUT the dissolved substances. So by using the available water, more energy is used than produced. A loss which means negative energy on useless machine. Fuel cells. Most fuel cells are run by using the energy produced by the water formation reaction using hydrogen and oxygen. (Step 2) However, the sources isn't water. Hydrogen are derived from alcohol or hydrocarbon and oxygen from air. Our best hope? Bicycle! Lol. Share this post Link to post Share on other sites
sheepdog 10 Report post Posted August 10, 2010 Water will never be able to power a carWell now, wait a minute. Since we live in the forest, I have always thought it would be great to have a steam powered car. Wood is free for the cutting, though of course you do need a little gas for the chain saw. You would think with all the great minds in the world, we could come up with a solution to the gas problem. Wonder whats taking so long? And we need local solutions and a variety of choises. Wood is easy to get here, but certainly not in the desert. Sea water is non existant here, but that would be fine for costal areas. Share this post Link to post Share on other sites
