has anyone added an extra alternator to their vehicle

[alecracing]

I saw a video on you-tube where a guy added an alternator solely for the HHO generator. He was pumping out 40 volts ( iforget how many amps). Reading the book I see that the alternator is the weak link in creating A LOT of HHO, just wondering if anyone tried this?

There is NO reason to add anything. As you now a alternator (you may know or not know ) needs ( a min of 12v) power to go from DC to AC ( which the alternator is doing )and then go back down to DC to maintain a consant load.

RE:I allso saw a vid on U tube. the guy added 4 alternators. I personaly think its a good idea to add one. If ya got room for it. the extra juice ya need for yur hho gen. would then not efect the cars electrical system that was made to run its own stuff like AC . heat, lights exc...20 amps or more is a lot to add to auto any system

The amps is generating HHO and not the volts. If the generator(s) requires much more than 20-25 amp than better build another generator:- play for safety.

You really need to reduce the volts. You only need about 1.5 per cell. It is the amps that produce the HHO. The problem is that too many volts with high amperage generates heat. All those volts that are not needed to produce gas will convert to heat using Ohm's law, unused volts multiplied by amps = watts and watts convert to heat. Just think of the amount of heat a 100 watt bulb throws out. Increase the heat of your electrolyte and it uses more amps. Heat production is raised even more. That is the reason we try so hard to control/reduce the voltage. If we could dissipate the heat as fast as we produce it there would be no problem. That is one of the problems of using plastic containers. They conserve heat. Many of us are now using a separate tank to increase the amount of electrolyte. Thermal hydraulics ensure a circular motion of the fluid. The volume helps with heat dissipation. Of course we have created the problem of available space.

I'd be interested in seeing a diagram/drawing of the separate tank increasing the electrolyte, how it connects etc.

This is what a PWM is for.......

Yes, I have done many such conversions. I am a retired pro mechanic. There is no problem adding alternators, the have their own voltage regulators. Modern alternators shut down at 13 to 13.5 volts. The amperage draw will meet the need. For example if 10 amps are required, that's what the alternator will deliver.
This is my first try at HHO. I am building a Hydrogen generator out of 100% stainless steel. 3 inches diameter and 15 inches long. It will have about 30 plates, whatever fits in with an gap around of half an inch.
Australian design rules, require this apparently.
Your comments please. Llew

Hi all ... newbie self-build here ... on a SAILBOAT !

My engine is a single-cylinder 8horse diesel thumper ... one advantage on a boat ( as opposed to a road vehicle ) is the lack of frequent throttle variation ... another advantage is that my 65amp alternator has only 2 purposes ... 1 is to charge my battery bank & 2 is to power the HHO gen ... I am getting nearer to completing my HHO system ready for it's first test ... reading & learning as I go ... as I understand it, I would need around 2 volts into my electrolyser & not 12 to 14 volts as put out by an alternator ... how do I reduce my alternator supply to the electrolyser down to 2 volts ?

So .... no reply to this query by 22 Nov 2010 ... is this just not do-able or what ? ... I figure I would need to reduce the output from my second alternator ( 14volts 30amps ) down to 2volts with as many amps as poss ? ... not keen to power the HHO from my battery bank or from the primary alternator .... Help !
