Accurate Replications and testing of plasma electrolysis (LENR)

[Pirate88179]

Just a quick update.
I've been working on this for a while and should soon have some accurate results. Volume is now 2L and the plasma arc is stable for 1 hour or more at over 100w.This is vital as Mizuno, a renound electrochemist, found excess energy only after about 1000seconds. RF is no longer a problem after I drastically improved the input circuit from that of Mizuno and JLN. If you have ever looked at JLNs power vs time graphs you will know how bad the noise can be. I found that the easier method of boiling and measuring the weight loss gives an unstable arc in this solution and I went back to the more elaborate temperature rise method, very similar to that of Mizuno. Currently I'm running calibration curves against a resistive heating element. The calorimeter is no longer a Dewer flask and heat loss at higher temperatures needs to be measured and compensated for.  When I'm satisfied that the temp vs time data can be accurately traced back to the input joules, regardless of the input power curve shape, the tungsten plasma will be tested. I'm aiming for a system that can't be faulted and can be replicated by others with similar experience.

Best of luck to you.  I am impressed on how you are being careful of the measurements on your experiments.  I look forward to hearing of your results.

Things are still looking good.  I've just built a few gadgets to help me record the data accurately. I was having trouble recording the current through a shunt and into the DAQ, even though I used an isolation transformer for the variac. A few mV make all the difference. So, I built a high quality isolation amplifier, which works a treat.  After one hour there is no drift and noise is just 0.3mV.  I've rebuilt the thermometer amplifier using a precision in-amp and precision resistor, with no variable resistors. The result is noise of only 0.03 degrees.  To power all this I built a precision 10.00V +/- 30mV low temp drift supply.  I was worried about picking up noise from the plasma, but with the temp probe just millimeters from the plasma, there was none.

Have a look at the noisy current below. This is the current everyone is measuring with their multimeters. Surprisingly, because it is DC with a lot of noise, the cheap multimeters gave some good values, but nothing beats good old circuit design to start with. 

Here is some of the equipment.

Update on the calorimeter. As you can see in the pics I was able to determine the electrical input heat from a heating element by monitoring the temperature rise of the solution. I was surprized at how well the calculated graph follows the real power graph. I deliberately changed the power quickly a few times, to simulate some crazy unstable input,  although I expect the water arc plasma to be much more stable. The second plot shows the errors between the two. Only at the sharp power transitions there is considerable error as the temperature has not equilibrated quickly enough. These are easy errors to spot in the graph. Overall it seems accurate to better than 5% over the whole temp range from room to boiling point.  The LENR plasma is reported to give 20% or more heat out compared to power in, so this system should be able to detect the COP >1 event easily.

Here is my first attempt at cold fusion using the plasma electrolysis technique. Voltage was started at about 150 and as time progressed I cranked it up to above 200. The whole process too about 3500secs. It obviously ain't too easy to get excess heat as described on the net. One positive result is that the system is not bothered by noise.

very nice indeed !!
there is nothing like good quality data !

do you have any Vid of system running ?
or Pics?
