Ive heard about few cars in my area that did the conversion. They said it saved them a ton amount of gas actually raised there octane level to 110 which gave them more power? Anyone knows someone that has a hydrogen setup. Would it affect performance while racing etc? just curious about the pros and cons

I believe this is a sham. These "Hydrogen units" separate H and O from water and use the hydrogen as fuel for your car. Yes, that works. BUT, it requires a lot of electricity. Guess where that comes from? Your car's alternator, which is spun by the engine. So, all the energy you create from having a hydrogen fuel source is used to recharge the cars battery. Laws state you cannot use energy to generate more energy. You cannot do anything except convert matter to energy and vise versa. You cannot create matter or energy, this means nothing can be more than 100% efficient. I did a research paper on this

I believe it is more of a placebo effect. People driving easier because they want to be all eco, and that causes them to get better fuel economy.

O_O . awesome!

Not to mention the energy content of Hydrogen is actually LOWER per pound than gasoline. Most gases are. So you've actually got more energy in a pound of gasoline than you do hydrogen, why would you want the hydrogen?

Think about it, energy is stored in the chemical bonds. Hydrogen only has a covalent bond between hydrogen and hydrogen. Look at gasoline molecules. It's a big, giant backbone full of C's and H's with dozens of bonds. That's lots of energy compared to a hydrogen molecule!

I laughed when I saw these people marketing a "magic catalyst" that supposedly turned part of your gasoline into methane which would give you 60mpg. I wondered how that worked since you'd actually be decreasing the energy content of your fuel.

Nothing but snake oil I'm afraid.

Wicked- droppin' the science on yo' ass.

The whole idea behind hydrogen as a fuel source is you can compress it to 10,000+ psi. A tank of that equivalent to the size of our gas tanks can make a car go 300 miles or so. The problem is transporting the stuff. Obviously, you can't viably transport liquid hydrogen, it'd be too hard to keep cold. Another issue is a gas truck that carries enough gas for 800 cars, can only carry 80 cars worth of H.

Also, H carries about 3% the potential energy of gas. BIIG difference.

Agreed. I work in the development/engineering of natural gas engines, so I know all about the tradeoffs of complex hydrocarbons versus simple.

The difference between H2 and CH3 is that CH3 is ridiculously abundant, there's already a network of it, and it's about 1/3rd the cost of diesel, going by diesel equivelent gallons (DGE).

We've got trucks that run with behind the cab CNG tanks that give us about 600mi range. The enclosures are as tall as the sleeper and 2' wide, certainly bigger than a couple of diesel tanks.

Not to mention we've also got LNG capability, the same way you can have liquid hydrogen. This time the energy density is about the same as diesel. But there's lots of problems associated with using liquid gas as a fuel, so it's another trade-off. Nevertheless, there's actually a large chunk of LNG trucks running around in California with our engines.

So if you are thinking of converting your car, go CNG. Some customers have seen a return on investment in under a year thanks to the low cost of fuel.

Oh, and did I mention that we are making the same power as diesel with these?

I use premium. I get 20+ MPG with 412 HP. I'm happy.

The motor octane number of hydrogen is very close to zero, so be careful injecting this shit!

Know a guy that blew up a perfectly working truck doing this HHO nonsense.

Moreover, its all a bunch of bologna.
