What everyone seems to forget when quoting thermal theory is that the H2O-HHO process is not creating energy, but using an existing source…water. Just as gasoline is converted to heat in a gasoline engine using less than 5 amp@12VDC, H2O is converted to HHO at 50amps@12VDC resulting in 3 ltrs/min of HHO which is injected into the engine as a supplement, not a primary source. I have a 2007 Dodge 3500 with a Commings 5.9 diesel engine that averaged 16.7 mpg over a 6 tank (100 gal)of fuel. After installing the fuel cell the Dodge and doing nothing more,it now average 24.2 mpg. You can do all the chalk board and theoretic mental masterbation you want, but the proof is in actual application.

The claim by some HHO enthusiasts is that HHO allows a more efficient burn and the extra enegy comes not from some mysterious new law of physics but from unburned fuel that would in a unmodified Automobile not be converted to usable energy, ie. it goes out the tail pipe.

That said, we are far from having a national hydrogen infrastructure that would enable a hydrogen-burning car to travel much further than southern California, and I have yet to read or hear of anyone who has driven an HHO car cross-country solely on the gas mixture. If someone has, then let me know.

Ditto creating your hydrogen to squirt into the combustion mixture. That energy ultimately comes from the engine. Now I confess I do not know the answer to this question: is the energy loss offset by an increase in gas mileage? In other words, if the engine needs to burn a little bit more fuel to electrolyse the water, in the end does the car actually go farther on a gallon of gas? At this point, I am not entirely convinced that using hydrogen (or “HHO,” which is the actual topic of this post) makes that dramatic a difference in mileage. There are plenty of scams out there, and my post was to caution people expecting HHO or hydrogen to be some sort of miracle “free” energy source. TANSTAAFL.

For my money, I’d switch to a diesel car and burn used vegetable frying oil. That seems to be a more reliable, and safer, technology than messing around with hydrogen and oxygen mixtures.

BECAUSE it actually produces a CRAPPY brittle weld

Now the alternator only produces what the car and its electronics demand at any given moment. It is CAPABLE of producing in the range of 80A on some vehicles and heavy duty ones can produce up to 120A. Putting an extra load on the alternator by running an HHO generator @ 20A will have almost NO negative effect of reduced gas mileage. Have you noticed any decrease in mileage just because you run with your headlights on? They draw 20-30A when on. The air conditioner doesnt draw power from the alternator. It creates “drag” on the engine by engaging a mechanical clutch connected to a pump. Yes, the ac compressor is just a pump, it siphons mechanical enery, not electrical. Only the fan that blows the air out of your ducts draws any electrical energy. Try this. Start your car. Turn on your lights. No RPM change. Now turn on the wipers. Still no change. Turn on the radio. No change. Turn on the fan(not the AC, just the fan). Again

no change in engine load that would require the engine to work harder. Turn on every electrical thing in your car and all you are doing is drawing on a

RESERVE of electrical energy already being produced by the alternator.
