brassknukl and 98rcmaro are talking about two different types of hydrogen fuel technologies.
What brassknukl is referreing to is oxyhydrogen or "Brown''''''''s Gas" where a motor achieves hydrogen from water through electrolysis (as mentioned by brassknukl)
What I believe 98RCmaro to be referring to is the use of hydrogen fuel cells. Where hydrogen gas is used to react with oxygen to produce electricity and water as a by-product. You are correct about your statement though. Hydrogen fuel cells in vehicles is a very unrealistic alternative source of energy.

very exiciting stuff
but i think its diffrent from conventional electrolysis
seems it has something to do with pulsing of around 30 (roughly) amps
and you want be carrying around tanks of water. you need to look into this more if you dont understand what im talking about.
the one guy (stan meyer i think) predicted gains of 700% energy output
which is essentially zero point energy.
which means for every 1 you put in you could get 7 out.
imo this is world changing technology if it can be prefected.
its basically unlimited energy that could easily be hooked up to every car on the road.

And that my friends, is the comic I was refering to. People don''t want to give up their horsepower, and many don''t like change. While there are amazing technological advances being made, many people will not want to cut gas out of their lives.
For now, electric cars are the most realistic. Plug in, charge, drive. You don''t need any fancy fueling stations, and most of the technology has been around for many years. One area that arguably needs strengthening is battery technology. Lithium-ion batteries are very efficient, and fairly lightweight, however, they are considerably more expensive than your traditional lead-acid batteries. As more advances are made, the cost of lithium batteries will decrease. Only then will electric cars be even more suitable for long-distance traval.

Surprisingly, this topic can be very controversial. Now I agree, an alternative fuel such as hydrogen would be a great thing, however, right now nor have I ever seen a production hydrogen fuel cell vehicle around. The effort is commendable though. There are however hybrid electric vehicles in production along with dedicated electric vehicles. Listed below are 5 issues with hydrogen fuel cell vehicles.
- Current fuel cell cars cost an average of $1,000,000. This cost has to drop.
- Current materials cannot store enough hydrogen in a reasonable space to give you the range people want.
- Hydrogen fuel is wildly expensive. Even hydrogen from dirty fossil fuels is two or three times more expensive than gasoline.
- The need for an entire new fueling infrastructure. Someone''''s gonna have to build at least ten or twenty thousand hydrogen fueling stations, before anybody is going to be interested.
- Competing technologies will improve over time as well. You have to hope and pray that the competitors in the marketplace don''''t get any better. Because right now the best car in the marketplace just got a lot better, the hybrid vehicle...

Thats what I was hinting at, but you pwned it square on the head, lol.

*sigh* okay boys lets do some chem here shall we.... hydrogen fuel cells are going to the only sort of hydrogen that is going to work and heres why. what brass is talking about is taking water H20 and breaking it down into its components of H2 and O which is fine you create the hydrogen gas... then... allow the Hydrogen to combust ....combust is just a fancy word for react with oxygen I.E turning it back into water and generating energy. sounds great right whats the problem?!?! heres the problem.... in chemistry it take more energy to break a bond than it does to form it....meaning your going to be spending more power turning water into feul than that feul makes turning back into water ....basically meaning if that car even moves ..... its not gonna do it fast
i understand this. and i understand that normal electrolysis is slow and uses more energy than it produces.
the reason for my exciteemnt is because these devices apear to be breaking this bond with ease:
watch \/
http://www.youtube.com/watch?v=nOGAkRkCWfA&feature=related
watch the other videos too.
this guy ran a dune buggy off just water with his device.
now i realize this is the internet and anything can be fake. but why would so many people do the same fake experiment and post it.
and if anyones getting pwned on the head here its all of us.
we all are still filling up our cars with gas and making no effort to fix the situation.
