I can see stopping at a store for bottles of water

Hey that's pretty nifty! Cheaper than oil.

Note the narrartor says hydrogen not water

What a pile that is. Nothing can run on water. And if you look at the so-called "energy generator" in the back seat, it has a cooling fan on the side--an electric cooling fan. Sure, I believe that the car needs to be filled with water, but there then has to be some other energy source to electrolyze the water to separate the hydrogen from the oxygen, and that is a process that is far from energy-free.

The fact is that water contains less free energy than hydrogen and oxygen so energy must be added for them to become separate entities. That same energy is released when they combine back to water to produce energy. The thing needs a charger, solar cells, or something for energy input, and the energy from the water, due to efficiency losses, will never be as great as the amount put in by the charger. That is just simple thermodynamics, and that video is seriously misleading.

Even in scenarios where bacteria use enzymatic processes to break down the water, the process is not "free". The bacteria need to eat and anything they use for an energy source needs to be put in. Not even bacteria can make something out of nothing.

Thats why in the US and very few in canada theyres hydrogen refilling stations not many but at least they have some I supose check out the honda FSX that runs on hydrogen its much more interesting then this one

That so-called "water car" is going to need a lot of cleaning. Can you imagine all the crap that will be in it after lime, tea, and all the other junk that is in the water starts to accumulate in the thing?

Tell me about it and think about how You get the so called 'Just normal water" into the car take a garden hose and let it sit for a few hours I supose or spend hundreds of dollars on bottled water :P who wants a noisy energy sucking machine in the back seat of a car thats already small that would probaly take hours or days to get the energy to power the car but I suppose its what we expect froma prototype ................ From Japan :P

I like the "Energy Conversion Module" that was glossed over, that's where the real problems occur with this idea. As mentioned, there's some serious energy required to convert the water into hydrogen!

[MikeSwim07]

That is definitely not the answer to the energy crisis...

The trouble is that probably 9 out of 10 people will believe this is true and that you and I are just slaves to some ancient, outmoded concept of energy conservation. After all, those ideas are from another century. When are you and I going to get with the program?

Somehow this all reminds me of an idiotic TV commercial where the guy says, "After all, gravity was just a hunch at one time." When exactly was that? Back in the days when everything was floating around and drifted off into space? Thank God that Sir Isaac thought of it, but if he hadn't we would have saved a fortune on shoes.

They're the same people that believe we'll solve all the energy issues using windmills and solar panels. They're only one piece of the puzzle, and without Oil, nuclear, coal, etc., we'll still have the same issues. There really is one born every minute, I guess the scam artists depend on that.

[Elvandil]

I like the celebrities that think they are so "green" by building energy self-sufficient homes. The amount of environmental damage they are doing by building any home at all is almost inconceivable. From the 1000's of gallons of water used and the pounds of toxic solvents that come from making solar panels, to the waste products of the manufacture of the other housing materials.

If they bought an old, already-built house, they would do the least amount of damage to the planet.

I want one, Im becoming my room to eco-friendly

If you want to save energy, don't drive anything, don't heat or cool your house, don't bathe, don't wash - or even wear - clothes...oh, and eat all your food raw.

That is basically what it boils down to. Anything you do to expend energy, anything that increases the entropy of the universe. If the old Indian tradition of leaving a spot as much as possible as you found it were followed, we would have to give up everything. And who wants that?
