The need for distilled water is simply to keep the unit clean. As the water is broken down any impurities will remain. Eventually the generator needs to be refilled as it'll run out of water. The impurities continue to build up and will eventually short the generator.
The OP's example is a bad design and 100 amps is a ton of energy. I've seen generators running on 5-10 amps that produce a fair amount of HHO. I can't remember (I have it written down at home) but IIRC there is one that is claiming 60 lph @ 10 amps I believe. This is supposidly enough for most car engines.
The oxygen gets drawn into the engine and is used as part of the combusion.

On modern EFI engines would EFFIE's(?) to spoof theO2 senors be required to use the kits?

^^^ Yes they sell those for EFI engines with o2 sensors. I also saw an adapter for the o2 sensor. It moves it fiurther out, but not sure how that would trick it...

The EFIE is an okay device for altering closed loop mixtures a very small amount. However, once you start leaning things out too much you go beyond the intended use of the sensor and the resolution becomes horrible. Here is a chart that shows AFR vs O2 sensor voltage. As you can see, there is almost no voltage change at higher AFRs.
The $olution? Use a wideband O2 sensor. They allow proper resolution for higher AFRs. All the new systems can simulate a narrowband sensor's signal, and you can set the AFR at which it operate in closed loop mode. For example, I can tell the wideband system to say 17:1 is stoimetric and it'll keep me at 17:1 while in closed loop.

I have an HHO generator from www.hydrogen-boost.com. just like Daox says, I haven't had any results. However, I have not been willing to implement all the mods required for "the system" to work. This includes MAP and 02 sensor spoofs, and a fuel heater (using waste heat from engine coolant).
If I had to do it all over again, I would seriously *consider* this gizmo :
HydranOx - $400
http://www.sigmaautomotive.com/hydro...x/hydranox.php
The reason I am curious about it is that it *claims* to separate the H2 from the 02. If the gizmo is only sending H2 into the air intake, this would remove the need to modify the 02 sensor, which I like, . But, I wouldn't pump the 02 into the cabin of the car, that's for sure.
I am not saying that the above gizmo is not a scam, I am just saying that it claims to solve an existing deficiency with HHO designs.

Hydro 4000
Hey guys, do me a favor help me make an educated decision on this product .. It is a Hydrogen generator, the website is hydro4000.com
I have seen the product first hand and my dealership is looking to back the product for sale. These guys got their lucky break by giving a unit to the local news station to use on their news van and saw positive results.
Just by using 15amps of power this unit creates hydrogen which is introduced into the intake manifold after the map sensor. Because of the low current the creator says it takes about 30 days for the unit to begin producing hydrogen efficiently. Several customers that come to my work have them and say it works. But with testimonials like; " I go to the gas station less" & "My car feel more powerful", I get real suspicious.
I know one of the benefits is it burns off all carbon build up, resulting in a better runing engine and of course if you percieve you are getting better mileage, you'll drive that way to see results.
Like others, it uses distilled water to refill and claims that you have to fill it up every other tank. I've seen the kit and it is well made, I am just concerned about the free flowing hydrogen into the intake and the ecu's ability to compensate for fuel.
Take a look at it and let me know. Thanks ...

I navigated to the Paypal. They want $1200 for it, so I say no. For that $$, you should make your own.

Believe me its not for me ... my dealership is going to invest in it as a distributor, with an installed price of $1799 We have the demand for it already, I just wanted some fresh eyes to look it over in case there was something I missed. It looks and sound theoretically possible and they have done a butload of research to make sure it generates the proper amount of gas and such.
I just figured if anyone could find flaws in this we could .. LOL

Hey guys.
I am in the middle of building my own generator but not from any purchased plans. I researched a couple designs and choose one to start off with. I also bought a scanguage to get some data for an A-B-A test of my build. I plan on trying a simple mod to send a slightly higher voltage from the o2 sensor to the ecu to make sure it leans out. Also going to try to retard the timing if needed.
The only way this will work is if the hydroxy gas makes burning gasoline more efficient to make up and exceed the electrical losses in the generator. We will see.
I am waiting for the correct electrolyte, aka, NaOH (sodium hydroxide) or KOH (Potassium hydroxide). These are cheap as well but you either have to order them online or have a soap making supply shop near you.
