I'm at about the 5000 mile marker now on my HHO setup and last night I took out the plugs to see how they looked. I am the second owner but the original owner told me that he had never changed the plugs so I can say that they are the original factory plugs. My s2000 has 50000 miles on it (including the HHO run) and based on my experience with other cars I've owned, and looking at many charts on line I will say that the plugs look great. With them out I could look down in the engine and see that it was very clean inside too.
I have changed the setup since my original post. I now have a small, 8 pound deep cycle marine battery in the trunk that is constantly recharged by a paper thin solar strip that I mounted inside the back window. I don't have to drive too far to work so the battery runs the HHO cell perfectly. I'm in Florida and my car is parked facing South into the sun all day every day so I never have a charging issue. The whole HHO/solar cell setup cost me about $340.00 and with the miles I've driven/gas money I've saved so far, I'm about half way through paying for it all.
I got really tired of everyone telling me that it wasn't free energy (which I never said/thought it was) because I was using gas/alternator energy to run the system, so I just bypassed the whole issue with the solar cell.

I still average about a 20% savings on gas.

 

What's HHO?

 

^what he said

 

HHO is a mixture of H2 and O2 with steam, produced from the electrification of water, that is used as a suplimentary fuel. It's also called brown's gas and is similar to water methanol injection in its function but it runs all the time, not just on demand.

 

looks like a lot of chemistry.

 

Interesting...got more details on how it was installed and how it functions.

 

your car also runs and smells cleaner.. but if u dont do anything about the a/f sensors.. your gonna burn more gas since running this system also creates alot of oxygen to run down the tail pipe and you know if the a/f sensors read too much oxygen its gonna riching up the mixture

but i think i talked to you about this and you did something for the sensors so it wont run rich.. if it wasnt u i talked to i guess you got it to work.. no dogging your system because i got two guys i know are doing the same thing

 

Very nice, solar panel + extra battery is an awesome idea, now you just have to figure out how to produce the reacting agent out of nowhere . I keed I keed. Nice work, keep us updated.

btw I still have yet to make one on my parents spare car, haven't had time but will eventually.

 

I can understand why you're doing this, I think, but I can vary my economy in the S more than 20% just by changing my driving habits.

I've gotten 26mpg mixed city/highway in this car.

I think you'd be doing better if you used something like an Optima yellow top, and eliminated the extra weight of the spare battery in the trunk.

Consider me a pessimist, but I just don't see how this really makes a significant difference moreso than just changing driving habits.

 

I am working on getting a HHO setup on my parents civic for them. If it works out I may give it a try on one of my cars too.
