    You do realise that that ahs been addressed on one of the other threads?

    Besides, HHO gas is a pile of junk. Can you explain to me what it is and how it works? go on, give it a try, surely its so simple that you can understand it?

    if you go to the link in my post you will see that it was on my local news channel. i have no idea what hho gas is furthermore i was under the impression that to seperate hydrogen from water takes more energy than its worth.

    Yes, precisely. So, the chances are its a total load of rubbish.

    Oh please! Do you have any idea how reliable your local news channel is... especially when it comes to anything scientific?

    If you don't understand this, what makes you think that anybody at the TV station does either?

    You were right to think that separating hydrogen from oxygen requires more energy than you can get back out by putting them back together. Apparently you have good sensible instincts, which is unfortunately not something a lot of people have. Perhaps you should trust them more.

    Oh man, all you have to do is burn ethanol. On the other hand, it takes forever to split water with a battery and some electrodes. Took me about 30 minutes to get enough hydrogren for my purposes.

    Water can be used as fuel, definitely so!

    Mu-ha. Ha.

    just because you cant do it doesnt mean no one else can.

    That philosophy is (hopefully) true about creating world peace, but it does not apply to violating the fundamental laws of the universe. We're not talking about something esoteric and barely understood like the impossibility of faster-than-light travel or whether the universe will eventually stop expanding. We're talking about what is arguably the one principle that underlies everything that happens in the universe: entropy. It's so fundamental that it requires virtually no scientific knowledge to understand it. You simply cannot extract more energy from a system than you put in because it isn't there.

    Hey, when did you start getting interested in science, Fraggle?

    About 50 years ago. I went to CalTech. I often post on the science and technology forum.

    Valich: (and everybody)

    There's no dispute that hydrogen can be used as a fuel. Energy has to be converted into a medium that's safe and convenient to transmit, store and/or transport. Whether it's generated by hydroelectric turbines, nuclear reactors, fossil fuel combustion, windmills, or a thousand frolicking hamsters eating the nuts you grow on the back forty, you gotta get it from the place you generate it to the place that folks are gonna use it. That means you're willing to consume (i.e. waste) some of it to get it there as one of the costs of using it. Electric power lines waste a lot of power. So do internal combustion engines. So do power generation systems, for that matter. Energy loss is rampant throughout the system. Residences and transportation probably waste half of what they consume.

    Converting the kinetic energy from fossil fuel-burning steam turbines or the hydroelectric turbines in dams (I think those are the two most common kinds of power generation in the USA) into electricity and then using the electricity to break water apart into oxygen molecules which you release into the air and hydrogen molecules which you trap in a tank and sell to people is probably more efficient and definitely better for the environment than the sloppy technology of cramming it into a battery.

    But that efficiency is still negative. You do not get as much energy out of the hydrogen as you expended zapping the water you got it from!

    Look at it this way. If the universe worked that way, you could just turn around and burn the hydrogen you produced right there in the same power plant, and use the heat to generate electricity. The hydrogen becomes water again. Use the electricity to hydrolyze the same quantity of water, and you'll have a little energy left over to sell or use to run your house. (Because of your hypothesis that you get more energy by putting water molecules together than you spend on breaking them apart. These are your rules here.) Keep doing that over and over. You'll be using the same hydrogen, converting it back and forth into water, and each time you'll have extra energy. If we could get everybody in the United Federation of Planets to do this, pretty soon our galaxy would have more stored energy than we could possibly use. And we would not have used up any resources! We'd just have a vat full of really worn out water.

    How many people think the universe works this way? Please tell me that the U.S. educational system has not gotten that bad.

    Valich- youve confused links about hydrogen fuel cells, which we all know about and are pucka science, with links to dodgy sites looking for suckers who think that hyrdogen for their car is free. Namely the "savefuel" website.
