Dudes - -you got me -- I am just a big "FAKE" -- only into ego tripping --
don't know nothing valid -- never did anything in my life except lie and con!!

You hold that dear to your hearts now that you have convinced yourselves of
it --

My loss??? I seriously doubt that!!

I regret I ever brought up this topic -- as "OBVIOUSLY" it can't happen!!

Look -- I never said truck engines -- I said small single cylinder diesels.

And how cares if you believe or not --

you don't like me "style" -- so don't do it!!

Art - -you have involved me in a most "FRUSTRATING" position -- I am simply
reporting on results to date -- and there you be -- making a super big deal
out of it -- as in it ruins engines -- etc.

Based on your trials -- right??

Come on dudes -- what is the purpose of technical discussions -- eh??

I know some people hear me message -- and probably will go through and try
it -- and gain from it - -and report back -- then Art can bash on them to!!

Jeez!!

Right now I am investigating state of the art battery charging systems --
better not report those results -- just more reason for folks here
to********* get negative3 all over.

Why would charging batteries be of interest to people doing gasifiers??

Guess -- eh??

Art -- you have succeeded in misdirecting a number of people in 3rd world
in regards to "economizing" -- congratulations!!

What an agenda you have!!

The person that did go on to run full bore at slow RPM was Ken Boak -- so
curse him out to.

I actually do not know if it worked or not -- but Ken -- if your still on
the list -- beware about reporting results from hands on work -- it is not
excepted by the "click" on this list!! (unless is agrees with their
preconceived notions only)

For your info Art -- I argues the full bore at low RPM thingy with Ken at
the time -- saying much what you stated -- so went ahead with under black
smoke operation at low RPM.

It's running diesels in black smoke mode that shortens their life
dramatically!!

It is very easy to design a set up not to black smoke at the average power
you will be using --

And they do not prematurely fail!!

Ah -- believe what you all want to believe!!

Me -- I believe what I have to believe -- not to "fail" --- and that
requires hands on prototyping -- nothing else proves a point as well!!

As for my being backwards here -- I work with equipments you can't even get
in the US!!

The thing on my bench right now is a derated DC power plant of exceptional
high efficiency just for charging batteries in the fastest -- most
efficient -- and durable -- manner.

It involves derating a 195 (you can't get those!!) -- using a PM DC welder
alternator (you can get on of those either!!) -- and marrying this all to
the right charging circuit -- and that folks is called:

All About MPPT Solar Charge Controllers

Theory, operation, and use of MPPT charge controllers for solar electric
systems.
What the heck is an MPPT??

This section covers the theory and operation of "Maximum Power Point
Tracking" as used in solar electric charge controllers.

A MPPT, or maximum power point tracker is an electronic DC to DC converter
that optimizes the match between the solar array (PV panels), and the
battery bank, utility power, DC motor, or DC pump.

Instead, the controller looks at the output of the panels, and compares it
to the battery voltage. It then figures out what is the best power that the
panel can put out to charge the battery. It takes this and converts it to
best voltage to get maximum AMPS into the battery. (Remember, it is Amps
into the battery that counts). Most modern MPPT's are around 92-97%
efficient in the conversion. You typically get a 20 to 45% power gain in
winter and 10-15% in summer. Actual gain can vary widely depending weather,
temperature, battery state of charge, and other factors. 

How Maximum Power Point Tracking works

Here is where the optimization, or maximum power point tracking comes in.
Assume your battery is low, at around 11.5 volts. A MPPT takes that 16.9
volts at 7.1 amps and converts it, so that what the battery gets is no
longer 7.1 amps at 16.9 volts, but 9.6 amps at about 12.5 volts. Now you
still have almost 120 watts, and everyone is happy. 

**************************************************

And yes -- I am into conserving energy -- that makes me a nut case -- so
what!!

But my customers here by units that cost much less to operate -- that is
our bottom line -- period!!

Here is how MPPT technology can save another 40% or so of diesel fuel ---

I derate the engine to run a lower RPM sweet point -- that sweet point is
not full bore!!

The diesel runs turning the DC dynamo at that sweet point putting out --
for a 24 V batter system -- say -- 32 volts.

The MPPT controller converts that to exactly the right voltage for maximum
battery charging -- at 94% or better efficiencies.

I'm looking at a 60 amp unit -- retail price in the US -- $200

They can be rigged to run parallel -- I need two for 120 amps -- which is
the sweet spot for the DC welder (100% duty cycle)

I probably can source the units in China for $30 each --

Ya -- we are so "backwards" --- no "grant" money -- for starters -- and
that allows me to do things considered impossible up your way --

How "STUPID" -- right!!!

I'm not stopping -- and your not even "started" -- let me know if you ever
even get started -- eh!!

Meanwhile -- keep playing with theories ---
