HHO is the gas resulting from electrolysis of water. Two H's and an O when seperated are very flamable. On top of being abundant it is cheap and cleaner burning than gasoline. Operating on purley HHO requires lots of modifications to a car but suplementing your gasoline with HHO requires little. There are a million sites out there on HHO car conversion kits. All of them are building plans for anywhere between 50 to 500 dollars. It seems odd that there is no instructable on it. So here, for free, is my attempt at making one. The text at the top is my first try and the text under the "-" line is my second try.
Step 1: Tools and Materials
This page ended up changing through the process and can vary depending on how you choose to improve upon the design I used.
knife or strippers
soddering iron(not essential but saves time)
*may change depending on the electrode you use and how you connect it to the wire
Materials:(Keep in mind all the materials I used are "borrowed" from work or I had around the house so they won't be the most effective solutions. Be creative with what you use)
Plastic container (I used a grape juice bottle)
High temperature silicone sealant <-expensive; regular silicone sealant MAY work
Wire (I used some left over wire from the amp that went in my wife's car, 14awg)
Plastic tubing (I had to siphon gas once to change the fuel pump and had this hose from it, not sure why I kept it but I'm glad I did)
salt (for an electrolyte in the water)
Stainless Steel Electrode(update: THIS WILL NOT WORK)
I put this one on bottom because it will have the biggest explination. I am told stainless isn't esential but will not corrode like other metals. I also read that coiled wire would be the best type(i.e. pipe, plate, wire).Platinum would be your number 1 choice but who can afford that? I used some pipe I found at work.
-I ended up using the graphite from 2 pencils as my electrodes
