I was wondering what it takes to build a HHO generator I cannot find a FREE guid anywhere. And also if it will work on fuel injected vehicals, a 2000 Jetta GLS to be exact.
1. A car battery/alternator gives about 4-5x the voltage required. (Extra voltage is wasted as heat.) The amperage drawn is governed by the plate areas and conductivity, (salt or acid content), of the water used. 2. Both plates are important. 3. You will not be making 'HHO', but an explosive mixture of hydrogen and oxygen.(Don't let any large amount accumulate or you are likely to regret it.) 4. You might get a small increase in ignition efficiency, (with the possibility of 'knocking'), but you will never recover the energy you waste. Can you spell 'dumb idea'?
To answer your second question first: no it won't work. These systems are nothing but a cruel scam designed to con people out of their hard-earned cash. Yes, you'll find plenty of people (some who will no doubt post answers here) that claim it works, I'm saving .% after fitting it to my car. Go to for more information But they are invariably lying. Why are they lying? Because these scams work by recruiting affiliates who are effectively paid to lie about the system. When they tell these lies and convince people to visit those sites, they earn up to $50 for each sale that's made. My investigations have revealed that virtually none of the people who join these affiliate schemes and promote these hoaxes save any fuel -- and that's because they don't even have devices fitte to their own vehicles - they're only in it for the money. But if you want to find out more about the scam and why the claims made for these water powered car systems are bogus, visit the site I've linked to below. And as to your first question: you can not build an HHO generator because there is no such thing as HHO gas. When you perform electrolysis on water (regardless of whether you use straight DC or pulsed DC), all that you get is a mix of H2 and O2. This mythical HHO gas they're talking about simpy dos not exist because unless they're in a plasma (ultra-high temperature), hydrogen atoms immediately bond to form a hydrogen molecule (H2). So there is *no* magic HHO gas, just a mixture of hydrogen (H2) and oxygen (O2) molecules in a 2:1 ratio. What's more, since only a tiny amount of this gas can be generated using the avaiable electrical energy your car's alternator can deliver, it does *nothing* to improve your fuel efficiency and in fact will *reduce* the efficiency. Now just sit back and watch the scammers try to tell you otherwise and refer you to their websites so they can make some money out of you. :-) Please tell your friends and family about this scam so they don't get conned too.
They are a SCAM, and don't work on any vehicle, fuel injected or not. You won't find a free guide because the sellers want your money. Not just my opinion, but the opinion of any competent mechanic, engineer, or anyone with any knowledge of basic physics.
