"Free Energy" is like "Magic", if you think it's real, you don't understand what's going on.

Free energy is a keyword. It does not imply that the government will give us free cars, or the industry would not try to profit from hydrogen power. As you can see with this car model, instead of the traditional combustion engine, they made it power an electric engine. The car would not be "free" but the fuel would be extremely cheap to free.

This car DOES NOT run on water. it runs on H which is used as an energy STORAGE system, not a fuel. More energy from some source (can be a clean source like wind/solar) must be put into making the H then can be recovered by rebuilding H2O.

The benifit of this tech is the fungibility of electricity, you can't generate petrol with kWhrs, but you can generate H from H2O using kWhrs.

Tecnically the car actually runs on electricity since that is the power output stage of the process? The point is that it generates electricity from a process of building and storing energy from H2O. Your correct it doesn't "RUN" on water. I suppose we should just say it runs on electricity. This way we can ignore the whole H2O being converted to hydrogen part even though that is where the "power" comes from.

I had no idea this would be so controversial.. The main point is that the technology exists - Clean energy. Global warming aside, I have asthma and believe me, I would soooo love to see these types of cars hit the market.. if only to breathe a little easier for all of us.

please get a clue. you are not "extracting" energy from water to run this or any other hydrogen powered car. hydrogen can only be used as dgandhi points out, as an energy STORAGE mechanism as you will always have to input more energy into the process of splitting water into it's constituent gases than you can ever get back out of the process of recombining them into water. you put lots of energy into splitting water into H and O then you GET BACK a portion of that energy by recombining the H with the O (burning it). this is 4th grade science. to anyone who knows how the thing actually works it makes you sound daft to say the car is "running on water" or giving "free energy" just as it would sound daft to say that your current car "runs on CO2" because the plants that decomposed in the ground that turned to oil over millennia originally produced their hydrocarbons by using CO2 in the ancient atmosphere. sorry but this is the sort of thinking that physicist Wolfgang Pauli rightly calls "not even wrong".

Free as in low cost fuel really is what I mean... not free as in something from nothing. I just meant that as a keyword in the posting (tags) because I figured it might show up in a search engine. I changed the title to Hydrogen instead of water. Maybe it should be Hydrogen/Electric but it would make the title really long.

The vehicle emits water vapors, I know it's not being powered by the carrier (storage mechanism).... it's an electric car that is powered by a process utilizing *hydrogen. I agree with dghandi on the process.. I was incorrect before about water being part of the process.

"it's an electric car that is powered by a process utilizing salinated water."

Actually, it's not, it's a car that's powered from Hydrogen, it has a hydrogen tank on board, not a salt water tank. Jeremy and James were discussing where you can GET hydrogen, but it's not like people will have Hydrogen extraction plants in their back yards for personal use, they will still go to a Fuel Station to get their Hydrogen... problem is that Hydrogen is kinda unstable, much moreso than petrol, so dangerous to deal with.

Otherwise, cool, cool car.
