Hi Timm,

> No procedures or methods exist other than those instructions and visual demonstrations presented by John.
You can always try to braistorm and come up with some of your own! Reading up on DC motors and generators would help. I know that the allegation is that the Kromery generator is a non-traditional generator, but it appears on first look to be a conventional generator where mechanical power pushes coils through a magnetic field, inducing current/voltage in the coils. Any energy transfer through the coils into a load will casuse a Lenz' drag on the electric motor that is powering it. When you run a test and watch it rotate, everything quickly falls into a balance. The input electrical power, the motor/generator RPMs and mechanical power transfer into the generator, the power going into the load and the lost power as heat all find a settling point. I suppose one possible question is does the settling point of the Kromery convertor differ greatly from a similar motor/generator setup?

I know that people will make a point about the unconventional nature of the convertor and traditional measurements may not apply. However, if you consider the convertor as a "black box" with the mechanical input on one side, and the electrical output that drives a load resistor on the other side, then you don't care if what's inside the black box is unconventional. You can measure the output power going into the load resistor. The voltage and current going into the load resistor will be conventional.

> • Anti-Lentz effect – The motor should draw less current when under load
That is a fairly complicated thing and it would be great if somebody really investigates it. In general terms, you would expect lower current consumption for when the generator output is shorted, and when it is open circuit. That's because in both cases no power is being transfered into the load. Somewhere between zero ohms load and infinite ohms load there is a "sweet spot" resistive value for the whole motor/convertor/load system that would put maximum power into the load and therefore draw the most current from the motor. So will the Kromrey convertor exhibit radically different performance curves than a conventional motor/generator in this case? I realize that the replicators might not want to take it this far with respect to making measurements, but you can always do some bacis investigations and then make some infrences.

> • Cool air streams should be evident in the area of the botch walls of the magnet stacks
Basically impossible to measure for the average experimenter but you can always make a subjective measurement!

> • The output should exhibit efficient charging of a lead acid battery
With respect to what? How do you define efficiency? Again, it would resuire some serious testing that perhaps only a die-hard would want to do.

• The lead acid battery should cool down when charging
> Easy measurement, looking forwards to the results. You are going to have to make sure the battery is out of the airflow generated by the Kromrey convertor because that would invalidate your measurements.

> Everything I've read and the primary point of the Kromrey patent is that the device will draw less amps when under load or shorted than when unloaded.
If it draws more current and slows down when loaded, I probably don't have it right yet. I still record the AC/DC output, I hook it up to a battery and watch the voltage reading on the battery. I check for cold air, but the device will move a lot of air by the armature turning.

I read that you recorded the AC/DC output, but you didn't mention if it was under load or not. Do you have a scope? The reason I ask is that the output waveform from the convertor will change under load because they have that output cpacitor in the circuit. It will be a pretty funky waveform, and you really would need a true-RMS multimeter or a scope to make accurate power readings.

> I have changed many things since starting...
Shaft composition : I'm moving to brass... have used 316LSS, Aluminum, Copper
I had granite spacers between the top of my pole pieces and the aluminum top/bottom plate... moving to aluminum spacers
Windings: I've tested #23, #18 and a couple different winding configurations.

I am no expert but I can offer my suggestion: All of your support components for the motor should ideally be non-magnetic and non-conductive. That way you will not be interfering with the magnetic fields or burning off energy as heat due to eddy currents. However, I cannot imagine that the materials you use will have noticable performance on the convertor. The main focus of the convertor is to complete a strong magnetic flux circuit when the coils line up with the stator magnets. Changing external parameters will have very liitle affect on this.
