Lugano resistance drop re-visited

am .

Could the drop in apparent resistance of the reactor heater element in the Lugano report be in part due to the core ceramic conducting at high temperature and partial shorting between the 3 phases?

There have been burn outs, core breaches, melted heater wire, hot spots and arcing thermocouples over the months.

Alan Goldwater deduced there was a drop in resistance in the ultra pure Al203 Coorstek cores we were using.

Additionally, SiO2 based ceramics resulted in plain shorts causing loss of thermocouples.

More recently, Adriano Bassignana made us aware of the Nernst Lamp

Of course, most replicators reactors to date have been single phase. So the differential between two adjacent coil loops where ceramic conductivity has increased would be lower than that between a parallel, helically wound, 3 phase coil.

Not about Lugano, but related to Rossi's Fluid Heater patent (http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-adv.htm&r=1&f=G&l=50&d=PTXT&S1=9115913&OS=9115913&RS=9115913 ). I just wanted to remark that:

was probably intended to be:

Quote:
...for example by heating the nickel powder two-four times at temperatures selected to superheat any water...
Try imagining this as it was Rossi saying it on the phone to his patent attorney.



(sorry, I didn't know where else to put this)

@Charlie

Closing the loop would do it too. i.e. all control and stimulation power harnessed from output to run reactor for beyond chemical possibility.

@Tom

This is the kind of Discussion that Bob Higgins and I had.

This and the wrong use of Emissivity means that for me, it all comes down to seeing statistically significant transmutations.

@Glowfish:

You will not perhaps think this relevant but:
3 phase makes it very easy to get an apparent COP=3 for free by inverting one of the input clamps on the power meter.

Without a proper power meter 3 phase makes input power measurement problematic.

The complexity makes errors in input power measurement, whether unintentional or deliberate, much more possible.

@Robert

All quantities RMS

For the same 3 resistive elements of equal resistance and 3 phase full waveform of line voltage V (we can revisit that later):

Y - resistor voltage is V, current is V/R, Power is V^2R

Delta -
resistor voltage is V|(1- (-0.5+0.866j))| = sqrt(3)V,
resistor current is sqrt(3)V/R,
power is I^2R = 3V^2R

The key thing is that delta increases element voltage by sqrt(3) over line voltage. compared with Y.

The Y equivalent resistance is reduced by the square of this (a factor of 3).

see wikipedia for details.

So for this to work we need:
Dummy run: Wye
Active run: Delta

Motivation? For limited range of V in from control box delta with give higher power than Y.

There are other darker possible motivations.

But motivation is all speculation.

What is fact is that the numbers given make sense for this change in setup, and given that the reactor must have been disconnected and reconnected such a change is possible.

The testers should have recorded this change, but we know that their work had issues in other areas - most notably a singular lack of controls of any kind (no independent temperature measurement, no dummy reactor at same power) and an error in how they calculated temperatures.

@robert greenyer after looking into inductors it appears you may need to open a whole new conversation on the matter. We may need someone in electronics to help. The reactor is essentially a inductor with a magnetizeable core which is the dual of a capacitor for electric the difference being it is a capacitor for magnetism blocking higher frequency ac allowing lower frequency dc to flow through in some cases, by setting up voltages and amperage inside of the core creating their own magnetic fields called eddy currents. Resisting the applied currents and voltages. these currents are probably what Rossi is tapping for direct electricit production but also goes back to me remembering a ground wire being connected maybe this bleeds off these eddy currents allowing the reaction to take place also could be bleeding off the electrons trying to conduct through the hot tube hard to say. The reaction itself may create it's own eddy currents but if there is already currents in place may not be able to co exist and therefore no reaction so you have to get rid of the applied currents (ie) the ground path. To much Wikipedia can anyone help with that

@ glowfish maybe phase angle, possibly inductance properties associated with the opposite coils and hot conductive tube, or having the three coils may act as a barrier for conductance of the hot tube some how saving the coils from destruction. hard to say really not enough info on it from rossi . but all I know is no one has tried it yet that I know of and I would personaly like to see it in action. just to call it a real replication of course. it would be nice to see a bare tube wraped with the three phase coils in a why configuration and recorded and then rewired for delta and recorded using exact same settings on power and length of time to compare something simple

A question. Why use three phase? Other than a little less energy ripple to the heater (which is not that relevant as the heater should have a long thermal constant) and perhaps a higher power source, what advantage do you gain for the price all that extra complexity?

@All

Nick Oseyko said

"I had tried heating mullite pipe with torch back in May. Becomes very conductive before melting. 1 cm gap was about 100 ohms."

Given that there was barely more than a few millimetres between phases in the Lugano reactor, and a large potential difference between them, this effect cannot be dismissed easily.
