The basic power generation mechanism of the new system is similar to that of a normal fuel cell, which uses hydrogen as a fuel. According to Genepax, the main feature of the new system is that it uses the company's membrane electrode assembly (MEA), which contains a material capable of breaking down water into hydrogen and oxygen through a chemical reaction.

I read this article and almost started pulling out my hair because of how absurd it is. To those of you who have already commented saying that this car doesn't work as advertised, I'd just like to say this: well done.
Apparently this car only needs water to run on. I guess they don't say what the exhaust is, but I have to assume that it is water (because there really aren't that many ways to combine hydrogen and oxygen, and water is the most stable). There is no way to take water, do a chemical process to it, and get out water and energy. It violates the first law of thermodynamics.
I'm not saying the car doesn't run. I'm just saying that water isn't where the energy is coming from. It could be from a battery, or an external source. Either way, water can't be reacted to form water and energy.
The company says that it has a special membrane that separates the hydrogen and oxygen in water to supply the fuel cell. It doesn't matter how this is done, it will still take the same amount of energy to do as you will get back from the fuel cell. More, actually, because nothing is 100% efficient in reality.
I'd like to say two more things to forestall any arguments. First, I don't need to know what process they use to split water into hydrogen and oxygen. It is one of the amazing things about thermodynamics that you only need to know the start and end states to determine where energy went in any process. Second, I'm a junior chemistry major, so I'm not just pulling this thing out of thin air.

That's years ago. He said he's into production years ago. And it's been years and how come nothing comes out of it?
And why the US military isn't interested in this. It's because it's a scam, hoax,fake, phony phony, PHONY!!!

Any official papers to go with that, or you "just heard it on TV"? Eh? Or was it just his claims?
Funny the TV said there was WMD in Iraq. Hmmmmmmmm...........

Eeeeeeeeeeeehhhhh.......
I was not asking for he's website "where you can purchase it for $6995". Remember about Steorn Orbo. Same thing.
I'm asking you about OFFICIAL papers or OFFICIAL military website that states they are contracting him. Where????? Where????
And if he was contracted by the military (which could well mean million or even billion of dollars) then why is he desperate to get money out of people's credit card?
This is really fishy indeed. Yup.
Eh?

The world can do without oil but it CANNOT do without water!

Free hydrogen is not an energy source; it is rather an energy carrier. Free hydrogen does not exist on this planet, so to derive free hydrogen we must break the hydrogen bond in molecules. Basic chemistry tells us that it requires more energy to break a hydrogen bond than to form one. This is due to the Second Law of Thermodynamics, and there is no getting around it. We are working on catalysts which will help to lower the energy necessary to generate free hydrogen, but there will always be an energy loss, and the catalysts themselves will become terribly expensive if manufactured on a scale to match current transportation energy requirements.
All free hydrogen generated today is derived from natural gas. So right off the bat we have not managed to escape our dependency on nonrenewable hydrocarbons. This feedstock is steam-treated to strip the hydrogen from the methane molecules. And the steam is produced by boiling water with natural gas. Overall, there is about a 60% energy loss in this process. And, as it is dependent on the availability of natural gas, the price of hydrogen generated in this method will always be a multiple of the price of natural gas.
Ah, but there is an inexhaustible supply of water from which we could derive our hydrogen. However, splitting hydrogen from water requires an even higher energy investment per unit of water (286kJ per mole). All processes of splitting water molecules, including foremost electrolysis and thermal decomposition, require major energy investments, rendering them unprofitable.
