Is the "Yes..." a response to my suggestion about the repair kit? Or are you just continuing another thought here?

Visualizing all results so far. Some points are averages of multiple runs. All data are for runs where water is lifted into the pump from a bucket below and for discharge heights either at pump level or above. The backpressure is calculated as…

Nearly ready for a run 0 ... 0.5 bar
Have a spreadsheet set up with one run per column.

Summary of yesterday :

Built the base of the tower.
Glitch : didn't get the pivot-screw exactly straight. (1/4 in 6" off = 4% error)
Not fatal, but tower tends to…

Your group's strategy seems to me to be among the sanest things I have heard on this site. But you are travelling the same road as the medical R&D community went down near the turn of the century. Large companies trying to…

If you have a photograph of the recirculator, or a schematic diagram provided by someone who saw it, or have obtained it from Mr Rossi and are making measurements with it, then that would be welcome.

It is at this very point that we traverse from hard evidence, photographs, plans, and measurements to things that are unseen and perhaps unseeable. Although I understand the attraction of arguing over these phantoms, maybe it is more…

After a coupla false starts .... I have a full-tower-height run, where everything matches (camera and timer, stroke counts). I checked the stroke counts every minute : correct within 2 frames per minute.

Off to hardware store, radio, poetry ... and…

Is this the repair kit you had in mind? It has order number 1023124 and the following specifications ...

Alan - Do you see obvious reason why the pump is under performing? Could there be deposits inside the liquid end from this pump's previous life?

There are maintenance steps in the Prominent manual that you might consider at some…

Here (left) is a picture looking down the inside of the E-Cat plant from the east end (i.e., from the end that does not contain the Big Frankies). You can see the internal reservoir (arrow) sitting on the floor with the back end…

(Quote from LDM)


There isn't really a height difference between the internal and external reservoirs. Not much of one anyway. Don't forget that the floor of the E-Cat plant is 3 feet of the ground.

The external reservoir is there so that water can be…

No. That head of pressure is tiny. The external tank West is describing is the one you can see sitting in its wooden cradle outside the red E-Cat shipping container in the photo I have attached. It is max 3 feet or so above the…

@IH Fanboy

The bottom yellow arrow in the image is a bit misleading. I think the person who drew it is trying to show exactly what you are showing with the corresponding arrow you have drawn near the top of the setup.

In fact you both have it just…

(Quote from IH Fanboy)


The image and its yellow lines comes from someone who is an tireless defender of Rossi and who says that he has in the past discussed some of this with Rossi directly.

The small blue arrows you have drawn in are wrong way around.…

Update including run 20C (arrow) and reference values from Prominent manual (red).

I predict 36.5 L/h

Update : new tower is built (currently at 14 feet, target 17) .... ready for a pressure test!
Then just need to saw 3' base from a 2x6 .... with a hand-saw ...

Good idea! I'll get it ready to go.


(Quote from Alan Fletcher)


I am NOT accounting for anything going on at the inlet right now. All pressures in the table and in the plot are at the discharge of the pump.

Edit: If you…

(Quote from IH Fanboy)


Only one data point so far. I assume Alan Fletcher will be conducting several runs with positive inlet pressure.

Updating Alan Fletcher's results to Aug 10. "Post #" is the number of the post (this thread) that contains the raw data. All runs have a small negative pressure at the inlet, i.e., water is drawn up into the pump by suction
