    Burning saltwater as fuel

    You kind of have to watch the video to figure out how it works but it is crazy. When you actually see the small engine moving under power from saltwater it is amazing.

    you can also start wild conspiracy theories about it if you want

    Pretty cool, but you have to ask the old "energy in vs energy out" question. No one addressed that in the video.

    Fresh water burns, too. Ask anyone who lived around the Cuyahoga in Cleveland in the 60's - or anywhere around Lake Erie. :-) Oh, wait - may be that's not too fresh...

    Follow the link, and the article says:

    "Mr. Kanzius and Dr. Roy say the question now is the efficiency of the energy, and are presenting the technology to the US Department of Defense and Department of Energy to investigate how useful the technology will be."

    Exactly. It is pretty cool, but how much electricity is needed to get that reaction?

    Good question, also what are the by products? Does it just release back into the air and turn back into water? What impact does the salt play? Can it burn without the salt?

    Re: Burning saltwater as fuel

    So.....he found another way to separate out the hydrogen from (salt)water

    This is not all that far fetched
    Electrolysis is the most common way to do it today
    A microwave oven uses radio waves to spin water molecules in the food
    Radio waves are just a very controlled electro magnetic wave
    so if you tune the radio waves to the salt in the water, you can generate some electricity with the salt in the water

    and bam flaims off a test tube

    thats weird, we just talked about this in my urban planning class today.
    seems interesting enough, anything deserves a chance

    it's neat he got a flame from saltwater... but you need to shoot it with radio waves. where do you get the power for the radio wave generator?

    last i checked, my microwave is already 1800 watts. wouldn't it be repetitive to have batteries power a radio wave generator, then burn salt water, then have a flame perform work? why not just have the batteries do the work?

    Interesting, but I tend to think you would need more energy in than you get out, as others have already said.

    If not, it seems like it would be a promising alternative. Obviously salt water is much easier to get than gasoline.

    yeah, you're exactly right. It all depends on the amount of energy input vs. ouput.

    Re: Burning saltwater as fuel

    Just on last question (ok two)

    Will the salt water support a flame after ignition ???
    Or does it always need an out side energy source ????

    Re: Burning saltwater as fuel

    It seems pretty gosh darn cool, but is it really all that efficient? I just see a lot of power loss coming from an automobile engine derived from this system. But, MAYBE it can be used for something else.
    I'll make a new sig. Later.
