    I had a video, before my PC crash, of a guy in California that had about the same thing. He had been driving it for quite a while I think. If I find it I'll post it for ya....

    wow....
    two unfortunate truths that this car will not be made available to the american public anytime soon.
    1- either limited availability or too much $$$ to purchase.
    2- politics of one sort or another...

    It's not what you think it is. It doesn't "run on water." A battery inside the car separates the water into H2 and O2, then burns that. So the water is irrelevant to the equation: the battery itself could just run the car. Separating and then recombining water actually loses energy. You'll have to recharge the battery offline.

    Somehow I doubt a claim that the Second Law of Thermodynamics has been repealed can be supported by one video from Reuters.

    What's the big deal?

    The USA had a truck that ran on water back in WWII.

    There's a guy in Jacksonville, Fl. showing his 'adaptation' of a welding generator that uses the hydrogen and oxygen seperated by the generator to greatly increase a car's MPG.

    Can't find the origional news story but here's a link to a similar product....

    To get the hydrogen and oxygen that the car uses for fuel takes more fuel than it would to just run the car. This is another case where 'thinking green' merely indicated a brain fungus

    Hey it's already higher than that.......a 16oz Disani bottle of water at the local 'stop & rob' is a $1.59!!!!...that's $12.75 a gallon!

    Sadly, most of the 'think green' schemes are just that.....All emotion & no serious thought. Look at incandescent vs. florescent bulbs.....yes florescent use less energy to give off light, but they use that savings up in the energy required to manufacture them. Then once the bulb fails you're now left with a pressurized container which has mercury vapor & other heavy metals to dispose of.....How 'green' is that?

    I wouldn't go that far. Many are, but quite a few are steps towards a better product. Sure, many of the alternative cars use more energy to convert their alternative source to useable energy now, but that's why they aren't really marketable yet. They are prototypes to build upon and improve.

    I'm with you on incadescent vs florescent bulbs, though. Less energy to use, more toxic waste left behind.

    However, the "Greens" often adopt "solutions" w/o considering the "problem of scale" and the "problem of unintended consequences."

    Bio-diesel and ethanol are good examples. What works on a small scale using surplus production, can have a major negative impact when expanded to a larger scale and the demand for resources overwhelms any existing surplus production. Large scale alternative use of land resources pushes up the cost of the other alternatives and the unintended consequences is that food prices go up. Then as the industry expands production to meet the growing alternative use, they increase the use of fuel and petrochemicals, which were not a factor when Bio-diesel and ethanol was just a minor factor utilizing surplus production of the existing operations.

    It goes beyond the Second Law of Thermodynamics. Some schemes also try to violate the Law of Supply and Demand. You can't get something for nothing.

    OTOH, we need to keep looking for those steps towards a better product. I did see one proposal that I thought might be worth looking at. Batteries have a weight problem as well as a disposal problem. (Yes I know that if everyone followed the law, disposal would be only an economic problem, not a "green" problem. -- But if everyone followed the law....)

    FWIIW -- The idea focused on the idea that storing energy as electricity is a challenge. This idea was that using off-peak electric production, (or even developing tidal or wind production where it is not currently economical because of it's nature driven production schedule being out of sync with the human demand schedule) to split water into hydrogen and oxygen as a method of storing energy until needed.

    In energy conversion you can't win. You can't even break even. Converting from one form of energy to another always "costs" more than what you started with.

    Now, if the battery can be recharged with solar cells, and nothing else, that might be a winning combination.

    But that would be negligible. Even if the entire roof of a car were a solar array, you'd still get at most 1 HP from the sun, ongoing, and only at noon on a sunny day, no other time. That puts to the side the issue of who would want to own a car with a solar array on the roof, plus what happens to the delicate, fragile array over time as rain, leaves, snow, guano build up on it.
