Electrolyzer Design: Very Low Voltage & High Current

[dennis13030]

Has anyone ever tried to use an electrolyzer using low voltages like 1.00V or close to this? I wonder if efficiency is better using very low voltages and high currents(like 100 Amps@1.0V).

Or maybe 100 Amps@0.1V??

If I remember correctly, you need something like 1.4v to create HHO.

More or less, the object of neutrals along with running generators in series rather than parallel drops the voltage going through the electrolyzer, to produce less heat and drop current draw.

I bought a small 12v, 1.3mA/hr battery from BatteriesPlus to test my kit, and it produced HHO quite readily. So did a 9v battery. AAs wouldn't do it. I think the threshold for production may have more to do with electrolytes than amperage or voltage. The 9v really heated up. In fact, I think you could get a 12v 7.3mA/hr battery from BatteriesPlus and set it up to run the HHO Generator separately from the battery. A 1000w charger costs $24, so you'd need to recharge the battery every 7.5 hrs, but it wouldn't take long. Few people drive 7.5 hrs at a time without stopping for lunch or something. By the time lunch was over it would be charged.

Ive thought this very same thing, I know what dennis is saying start with 1.5v and high amps instead of using neutrals to chip away at 12v if you start with 1.5v you could run a +- setup run in parallel. at least you would know you werent losing any voltage to heat. does anyone know how you setup down a 12v system ?

[dennis13030]

If I had the bench power supply I could do this. A good one that has the right capabilities runs between $500 and $1000. Most of this expense is due to needing a wide range of voltage/current and programmability. To run a matrix of tests, the programmability is a must.

Radio Shack, years ago when the CB craze was in, I purchased a resistor, or whatever you call it, to reduce 12v to 6v.

First off, our vehicle electrical systems will not produce nor handle current @ 100amps for very long without some serious electronics. The simplest way to do it is the standard 12V DC to 120V AC inverter and build a circut to take it back to DC and use a PWM after that because the system still cannot handle high current. The Pulse gives the caps time to recharge and can be utilized to pulse at the resonant frequency of the cell.

Second, why electronicly reduce voltage when you can use it with N plates or a series of cells for more plate area and production? Voltage, in basic terms, is the 'force' that pushes current. No voltage = no current. The more resistive a circut is, the more voltage is required to push the current through. While it may only take 1.4V to push 20amps through a set of two plates, it would require 2.8V to push the same 20amps through a set of four plates in series and production is doubled.

I would tend to go the oppisite way. High voltage, low current. It is easy to step or step down voltage. In a auto, our sustainable current is limited.

For the moment, I am just finding out if anyone has tried this. I'm on a quest to determine what setup creates the most efficient electrolyzer. At this time it is not intended to be put in a car or otherwise.

Here is my goal

Minimize the input power!

AND

Maximize HHO production!

[timetowinarace]

It's a good goal.

It stands to reason that given enough plate area more amps = more production.

I think Im with timeto we should be happy we have 12-14v to play with and basically can utilize neutral plates to step down the voltage.
