We have worked through a lot of problems and we do know what makes the engine sputter and sometimes stall. And we know how to make it stop. This is not to say that HHO is ever a perfect solution.
We also know that engines can be built better to start with so that there would not be any need for HHO. But gee, who is going to make an engine that burns less gas? Not GM or Ford. President Bush missed an important economics lesson some years ago. If the De Bears diamond company wanted to sell   more...a perfect 1 caret diamond for $25 they could by mining more of them. They don't want to lower the price so they control the supply. The oil companies can do the same. If they would refine enough oil early in the Spring, the surplus of gasoline would lower the price. They don't want to sell gas at $1.50 a gallon so they simply hold back the supply. Drilling more holes in the ground will not automatically increase the supply at the pump or stop the hoarding of oil into the strategic oil reserves.  less

HHO is an experiment that can and does work. It does have its problems. It might not be the best solution since it requires constant attention and effort to keep it working well. It works well in my Saturn, but the results are not consistant in our Ford.
The Saturn is a car that was built for fuel ecconomy and this is the kind of car that people should be driving. What people want is a huge vehical with power to spare and with room for six people. They will drive this to work each day alone   more...and wonder why gas costs so much.
The ultimate solution for families with more than one car is to have one electric vehical. With a range of only 100 miles per charge, this kind of car can get a person to work and home again each day. The drive to work and back is most of our diving and it accounts for most of the gasoline consumed in the USA.
This is why I am comitted to converting one of my cars to electric before gas reaches $7 a gallon. We can't live in the past. We might be able to live in the future if we are willing to adapt.

A few things that I insist on are that my HHO generators allow water to circulate freely and that they create turbulent water currents. All of the water in the generator must be in the path of the electrical current and must be directly active in the production of gasses. Only the water between conductive surfaces will electrolyze, ionize, and make gasses.

A good generator made better. I did something to the negative plate to increase gas production. It is all there on my channel for you to veiw. Just like the picture of the girl in the bathtub, you could see everything if it were not for those pesky little bubbles.

An important consideration concerning a pulse or an AC current is that a capacitor blocks DC and passes AC. So, if you construct the hydrogen generator like a capacitor with many close plates, the pulses will pass through and the circuit will aid gas production. My generator design was made to work best with DC current by spacing the plates father apart and using a very strong electrolyte.
