I think out of all the Hydrogen methods (not including brown's gas, I mean stuff that actually works. lol) liquid hydrogen seems to be the best, but it definately has drawbacks. Of course the H-bomb like you mentioned, and my favorite one is the fact that we can't keep it cryogenically stored in our cars for very long, so we could top off our tanks in the future, and then go on vacation only to return to a car that is out of gas because it all was vented into the atmosphere. I know someone on TV mentioned a long time ago about plugging in a hydrogen fuel cell car to your house to power your house when you are not driving...hopefully that would work the same way as solar panels where it will send power back to the grid and you can at least get paid a bit to offset the cost of all the hydrogen that was wasted while you weren't driving.

I would love to see more research into liquid hydrogen as a fuel, but right now it isn't practical or economical.

Mercedes Benz has a hydrogen fuel cell in limited production now.

The main issue with HHO is that you are trying to power your car with the same engine you are using to generate the fuel. That is like a motor hooked up to a battery which turns a generator to recharge the battery...eventually the battery dies because perpetual motion is physically impossible.
What does this have to do with perpetual motion. You are mining Hydrogen out of water and using it to boost the gas/air mixture.

Should have nothing to do with perpetual motion. Not free energy, Hydrogen is a chemical that would be added to Gasoline.

What you said would be like saying you can't pump air into your cylinder with the gas because there is no such thing as perpetual motion.

Don't get me wrong, I will not claim to be an expert and could be wrong but I have studied some stuff in school and what you said doesn't sound right. I also don't know enough about how much brown's gas can be produced by a car alternator or how much it takes to affect the performance of a gas engine, but have enough of an open mind to consider that the right amount of hydrogen could make gas burn much better and increase mileage.

I wonder what the OP has discovered?

The way it works isn't too difficult to produce and it doesn't require the storage of hydrogen. This system makes hydrogen on demand. The only thing you will need to store is a small amount of water, usually less than a gallon.

Basically what this does is send electricity through water with an electrolyte added such as sodium bicarbonate (baking soda) which will separate the Hydrogen and Oxygen and then using a tube attached to the intake, (usually just into the plastic intake after the air filter and MAF sensor). The Hydrogen assists with the combustion and will actually make your engine run lean as far as gasoline goes. Now running lean usually is very bad but in this case it isn't because the hydrogen is making up for the lack of gasoline. And after combustion the hydrogen and oxygen will return to H2O (water) in the exhaust. This process does require a decent amount of current usually around 20Amps and it will make a good amount of heat.

This is really a very interesting concept and more research needs to be put into this. Just do some research on the internet and you will find a lot of very informative information. I have a feeling we will be seeing HHO/Brown's Gas vehicles within the next 5-10 years.
what your saying has a very basic flaw, its kind of like perpetual motion. the amount of energy it takes to produce the hydrogen can never be less than the amount of energy combusting it would produce. you said your self that the process creates heat, this is effectively wasted energy. if anything doing this modification would DECREASE mileage. just think about it for a minute.

EDIT: sorry, didnt finish reading the thread, i guess this has already been adressed
