    Just wondering does it run only on water or just a hybrid?

    Just water, Any water. Even saltwater

    Just had another look at this and noticed that the video was posted 18 months ago

    Why haven't we seen more of this?

    The basic principle behind all these 'water powered' cars appears to be the electrolysis of water to produce 'oxyhydrogen', a gas consisting of hydrogen and oxygen in the same ratio as it is in water, i.e. 2:1. This is in then burnt in a (modified) petrol engine. What they never tell you though is where the energy is coming from to perform the electrolysis in the first place, i.e. electricity from an on-board battery of some sort. The electrolysis process, especially on this small scale, doesn't seem to be very efficient, making it less efficient than just using the electricity to power the car in the first place.

    See http://en.wikipedia.org/wiki/Oxyhydrogen and http://en.wikipedia.org/wiki/Water-fuelled_car#Electrolysis

    In short, it's an elaborate hoax.

    Yea there's several companies working on a slightly different version of the same principal, I think the latest is another Japanese company that are using a modified reva car and are trying to use a chemical reaction for the process.
    I don't think they've secured a patent on it yet and they're receiving a bit of hassle over some of the claims they have made.

    But afaik none of them have really proven to be anyway efficient.

    Yeah, the other way of supposedly making a car 'run on water' is to use metal hydrides which react with the water to produce hydrogen, but these chemicals deplete over time and need to be replaced. Of course, you don't get anything for nothing, and energy is required to manufacture these metal hydrides, so it isn't a water powered car at all, but a metal hydride powered car.
