If your interested in why, I copied this off another site since I didn't feel like typing out a conservation of energy essay.
If you convert 1 US gallon of water to hydrogen by electrolysis it will yield 420.6 g of hydrogen (H2 gas). If the electrolysis is 100% efficient it will take 16.821 kWh of electricity to crack 1 gallon of water. That 420 g of H2 only has an energy density of 14 kWh (33.3 kWh/kg * .4206). That's 16% more energy to crack the water than you get out of it. At 70 percent efficiency that means it would take about 24 kWh of input energy to produce hydrogen with 14 kWh of energy output.

The biggest hurtle with Hydrogen-powered vehicles has been trying figure out a way to keep it onboard in a safe manner. Honda has had a car out for a couple years now that's Hydrogen powered(IIRC, it's only available here in Kalifornistan in lease-form), but as far as I know, they're the only one.
I commend you for pointing out the most basic of faults with it- it takes more energy to produce than it produces.

Never mind I get it now haha I see its just a gimmick just got curious when my buddy texted me the link I posted on here and decided to see what y'all knew about it cause I thought it'd be a gimmick

The real test would be to see if with a solar panel and a battery you could overcome the amount of extra energy needed to carry the extra weight by using the extra battery to generate the hydrogen. My guess is that it would slightly but when you figure in initial cost and added maintenance you would be better off just spending the money on gas.

I have built 2. Cost is 15.00 maybe. I installed one on 2003 Yukon went from about 17 mpg to 24 mpg. With nothing more than stainless steel plates, plastic nuts bolts and washers, high temp sealant, some tubes and a mason jar. I have built one out of PVC that I will put on my truck in the next week or so as soon as I buy a pulse width modulator ( to keep from taxing my alternator ) when I can I may get a edge or some other way to reg the o2 sensor. It draws the gas into the air intake tube, so I want to decrease fuel and increase the o2. It has no pressure to explode. Back flow check valve ( in case the engine backfires, like that ever happen anymore but just I case) also make sure you hook it up so it only runs when the engine is running, not running when the key is on axu with out the engine using it. You need to check the water about twice a month, don't clean it. The roux' makes it boil better. High mineral content water is even better.
HHO burns hotter than Gas.
1. Using all fuel, not just a % of it
2. Cleaner burn, less unhurt deposit
3. HHO burns in the combustion chamber ( the cylinder )
It's not a end all, but every little bits helps.
For a generator or welder it works great. Not much change in temp after it comes to RPM Temp
I will put info up as soon as I get it on my new truck, and test it to work out some operation bugs.
