Picowatt - Why on this Beautiful Spherical Earth, would one want to go about using a Hydraulic Ram Pump by approaching the situation first by Filling a Water Head....

Its just NOT HOW one uses a Hydraulic Ram Pump!

A Hydraulic Ram Pump and the working principals behind the operation of it, use Natures Generosity... Rain Fall and existing Water Reservoirs and Gravity to Operate!!! Nothing else but these Principals.

I am not having a go at you, I simply just don't understand why one would approach an Energy Problem like this.

I would not use a ram pump this way.  I am quite familiar with them having built and used them in the past.  My comment was to make a point, that you apparently missed.

Do you define all solar powered systems as COP=infinity?  I do not.

Regarding the AC coupling issue, why not admit your mistake and move on.  That was 140 pages or so ago...

I can see now, why so many continue to fail in their search, its a mindset! Set to fail, not to open doors, to expect to fail, an out right expectation of: "You can NEVER get more out than YOU put in" says the big angry, aggressive Imperialist Voice...

I say: Up Yours, Energy is every where, its free if you can be smart enough to use it. I agree with Nikola Tesla and the plethora that followed, and the few that were before this great Man!

Your mind is yours, but I will say, waking up is amazing!

Better that the best one night stand you ever had!

Disagree with this all you like, its your choice!

Whoooow Chris,    Now you are talking.

Its a mindset!
This is the BEST STATEMENT on this forum thus far !!!!!!!!!

Picowatt,

   1: What's the point of using a Hydraulic Ram Pump then? I also have built Hydraulic Ram Pumps before. I certainly did not miss your apparent point...

The point of using a ram pump is to take advantage of a source of "free" energy

   2: Any System that YOU the end user does not have to put Energy into it, I consider as a COP = Infinity - This is my View...

A ram pump, or any other solar powered system, DOES require that energy be input to the system.  By your definition, apparently, any system that operates from a source of energy that has zero cost $$ wise has a COP of infinity.  I would disagree.  A COP of infinity indicates to me that for a given amount of energy input to the system, an infinite amount is available as an output.  That is clearly not the case with a ram pump or it would be able to run my elevated tank example forever.  Your definition is more appropriate for the term "free" energy.

   3: Best you go back and read the pages, I proved my point then and easily can do so again. There is nothing wrong with AC Coupling as long as one has checked for DC Offset...

As long as there is no DC offset AND the waveform has perfect symmetry above and below its zero crossing, there will be little if any difference between AC/DC coupling.

For the power measurements you were presenting, DC coupling was way more appropriate.  There is little to debate.

As for any errors that using AC coupling may have produced in your measurements, they were likely less than the greater error you make by defending the use of AC coupling.

If your probe and scope ground were connected as has been discussed in this thread and over at OUR, your major measurement error was not related to AC coupling nearly so much as the error produced by not measuring directly across your load.

But i thought that subject was all settled quite a long time ago.

Finally, some common-sense! Thank You Picowatt!

Yes

Yes

Yup and Yes

Good, we now mostly agree on some simple principals... Mostly...

Good, lets get on with it...

So, for each of the following waveforms, which should be selected on a typical oscilloscope:  AC coupling or DC coupling?

MarkE - Go and get a Job You Douche Bag!

Actually, I would like to hear your answer to MarkE's coupling quiz.

Your childish and insulting responses to MarkE and Bill were both uncalled for and inappropriate in the light of your continued defense of your use of AC coupling.

As I suggested to you 140 some pages ago, it would be most wise for you to understand and accept why it was more appropriate to use DC coupling when making your measurements.

Here we go again.

Ok, Picowatt, just for you: A, B, C, and D, I would do exactly what I did before, DC Coupling is what I would use for all waves....

Why, because none are AC wave with symmetrical formality

Now are we good to continue?

I mean, really, the Oscilloscope has a AC Coupling for what reason... Call any manufacturer and they will tell you exactly what I just said...

The reason AC coupling is an option is for convenient viewing and "measuring" of signals with large DC offset. The "measurements" however should never include making power measurements.

Since very few wave forms are completely symmetrical, it only makes sense to use DC coupling at all times when making power measurements. Call any scope manufacturer, and they will tell you that.
