Controlling Amperage
How do you control the amperage going to the HHO generator/what's a good power source?

not that I am agreeing with this stuff but simply answering the question

if you look at your generators as resistors, one simple thing you could do is series several of them together. another alternative is to use a PWM which pulses the voltage thus giving it a lower average voltage input thus giving it a lower current draw.

also a good idea in doing all of this is to have some way (ammeter) to monitor the current draw.

Ahh. Thanks. So simple.

On a side note, I'm a skeptic as well... But am givin it a shot anyway.

if I were you (and I am not) I would go with the tried and true methods first. if you want to experiment afterwards, that's cool.

there are just so many people playing with HHO that are still running around with 20psi of air in their tires and with their grill exposed and they seem to be doing it in a gas guzzling car.

I say do the easy stuff first. get your mileage up there, sometimes way up there. after all of that, if you still want to play with or experiment with other things, have at it.

when I say easy stuff, please see "201 tips to save gas" at the top of the page. I don't agree with all of them but there is some good advice there.

clamp on ammeters aren't cheap, especially if you get a good one (fluke). so if this isn't something you have lying around or readily accesible then all the profits of your HHO (if you ever see any) will be turned into equipment expenses.

If you own your own business you can always write one off as a business expense. Just last week I bought an infared thermometer, which is an indespensible tool for troubleshooting bad steam traps at work, but has many other applications, like automotive and in the kitchen... :D

Clamp on ammeters are $10 to $20 at Harbor Freight, but may only be able to measure AC amps with the clamp. I have one from there that I used to measure current draw on a bunch of servers. I added them up, sent the figure to the guy who needed it, and forgot about it until yesterday when I foudn a note from my predecessor about power usage...which said the same thing as my number. That's accurate enough for me. :thumbup:

Regulating amperage is very wasteful. You want to regulate voltage.

GasSavers_BEEF 08-09-2008 06:33 PM

if you notice my first post, the responses I had suggested just that.

there again, not that I am agreeing with all of this HHO stuff.

also, if you don't adjust the overall resistance of the generator, then the lower current can only be achieved with lower voltage. ohms law is a slap in the face sometimes.

V = IR

*EDIT* on a side note, the equipment I use is very accurate and also application specific. a network analyzer that goes up to 20GHZ. of course I work for a company because a basline model costs somewhere around 50k. there are guys that contract out and I am sure they charge a lot just because of the equipment they have to carry.

In reference to the deleted post:

i think "nice" is a relative term. the pwm that you are trying to sell looks like a college project using parts from radio shack. in fact, I believe I have just about all of those parts in my garage left over from some college projects that I worked on almost 10 years ago.

If I had to guess I would say that you are simply feeding the 12 volts through a chopping transistor and you have an ammeter on the setup. all in a neat little RADIO SHACK enclosure. If I were you, I would have went with the aluminum face plate. it makes it look more up-scale. so you could sell it for even more
