Jack, You are on the verge of the LENR precipice - where you dive off into the meat of the phenomenon. What you are seeing is that it is hard to discover whether anything special has been achieved. How do you whether something special has happened? Well, you need to measure the energy balance. Only if you measure more energy out than is put into the reaction with electrical power and chemical enthalpy, did something special happen. A big flash doesn't tell you anything. A flashbulb can be ignited with an AA battery and will make a very bright flash - due to the chemical energy of the burning metal. This spot welder will create a plasma hot enough to ignite many metals and when you put the water there it dissociates to provide a high concentration of O2 - you get the chemical effect of the burning metal.
Mills claims that his metal host is not burned and is re-usable. That must be a really refractory metal to not burn at plasma temperatures. Let's say that he is correct. The plasma still dissociates the H2O into H, O, OH, H2, and O2 and these will re-combine within the ejecta creating a hydrogen flash which will be very hot and bright. Did he produce over-unity? I wasn't convinced by what I saw that he showed. Jumping over the precipice, you will need to use one of the big copper arms as a current shunt. Connect a lead across two points on one arm. Use another calibrated source to run X known amps (lets say 10A) of current across the two points and see what voltage you get out. Calculate the shunt resistance as a calibration factor. Now you can use a digital storage oscilloscope to measure the differential voltage and capture the current waveshape. Next you need an oscilloscope connection across the two arms to simulaneously (with the current measurement) measure the voltage across the contacts - the connections don't have to be super close to the contacts because the voltage drop across the big conductors will be small. Then you can capture the voltage waveform. I don't think it will exceed 50V. To test, you can put a diode to capacitor across the gap and capture the peak voltage to know what you will need to protect against. You will need the simultaneous voltage and current waveform to calculate the input energy. There are other ways to do this, but this provides a lot of information. So how do you measure the power out? You can build a water calorimeter. In fact, you could fire the whole thing inside high resistance deionized water which would do a pretty good job of capturing all of the heat. You would need to put a blackened piece of pipe around it in the water to capture the light and thermalize it into the water. If you embed the electrodes reasonably well into the water, you may be able to avoid most of the error for the heat that goes into the electrodes. Calculate heat by temperature rise of the water. With practice, you will be able to measure the joules (energy) in and joules out from heat rise. You will need to stir the water and measure the water in multiple points. You will need an insulated container. Either that, our you need to be good at telling stories about the big fish that got away (is this Mills?). BTW, I applaud your efforts.
