2V & 60A reqd from car?

**Elliven** · 28th January 2009 11:19 AM

Hi guys

I am new here, (Hi!) far from an electronics fundi, and in need of advice!

I would like to a car's electrical system, as input, to get an output of between 1.4 & 2 Volts and around 60 Amps.

One option would be to rewind the stator of an alternator and regulat volage via the regulator somehow, but this solution is a little far from plug and play.

I then went in search of buck regulators that might be used for this:

How does a buck regulator work? - Ask Charlie - Blog on Control Engineering
http://designtools.analog.com/dtPowe...fA%3D%3D%22%7D
Linear Technology - LTM4605 - High Efï¬ciency Buck-Boost DC/DC ÂµModule LTM4605 LTM4605EV#PBF LTM4605IV#PBF
MIC2159 SYNCHRONOUS-itty™ Step-Down Converter IC
2 or 3 of these in parallel will work!
Micrel's Switching Regulators

So far it seems that buck regulators are suited to low amperage output by the very nature of their design.
If anyone has any ideas or input, it would be greatly apreciated.

It's unlikely that there's a cheap or simple option - switch-mode of some kind is the only way.

However, I suspect this is probably for some kind of hydrogen generating scheme, and is completely pointless as they don't work.

PS Generating HHO requires 2.5x the power it will produce.

As above.

The only time I've ever seen something needing that low a voltage and a reasonable current (still less than 10A though) was on a Lambda Oxygen sensor that required preheating so I assume you're after generating oxygen with that high a current.

Only if the HHO generator is 100% efficient.

He is adding HHO to a gasoline engine to fool the ECM into making the mixture too lean so the engine burns its valves and pistons. Then less gasoline is burned.
But the nitrogen pollutant will be way too high.

Yes; It is for a HHO generator.
Which means that it's going to be almost impossible to stick to the subject, get some help, and avoid an arguefight.

"ROUND # 1!"

Imagine that you had come up with an idea for using the wasted energy from an inefficient engine to produce hydrogen, rather than the obvious.

Imagine that you needed a nutter electrolysis cell to test required ignition and fueling changes as you only had one car and needed it to get to work!

Imagine that you did not have to tell the whole world the above and thus stood a tiny chance of making living out of your idea, with time to come up with other good ideas!

Your turn.

Do you want real answers based on real science or wishful thinking? How will an inefficient process improve an inefficient motor?
There is a site called overunity.com which has lots of HHO people all beating the same dead horse.
Here's proof it doesn't work, well worth a read.

That would be fine but you're not using the wasted energy, you're using useful energy from the alternator which will be wasted in making HHO.

If you used an electrothermal generator to generate the electricity to produce HHO then you might actually make a small fuel saving but I doubt it would be worth it.

PS is fundi a South African word for "expert in a particular field"

**duffy** · 29th January 2009 06:15 PM

In the US it means "Bible-thumper". Religious fundamentalism and belief in overunity schemes seem to go hand-in-hand.

**Hero999** · 29th January 2009 07:43 PM

Bible basher is the term we often use for zealots in the UK.

**blueroomelectronics** · 29th January 2009 07:51 PM

Remember there are no experts in the overunity field.

**duffy** · 29th January 2009 08:21 PM

Is a Bible Basher different from a God Botherer?

**Hero999** · 29th January 2009 08:22 PM

They there are, they're expert con-artists, liars and thieves.
