More Loading Data

First, I want to say thank you to all the folks following this experiment and contributing suggestions and helping look at data.  I have some more data for you to help me look at.  

Impedance of wire: The resistance of this wire has changed significantly more than Celani's original wire. R/R0 is now about 0.837.  This wire is 300 layer wire.  Celani's original wire in his demonstration was 100 layer wire.  

The temperature rise above ambient ambient has increased one degree over the last 8 hours.  Overall, it has slowly increased by 2 or 3 degrees.  A small part of that is from a small, as of yet, unexplained increase in the P_in.  Much of the choppiness in this graph is a result of a known fluctuation in the voltage from the power supply.

The Voltage looks like this below with a 0.2V sag periodically.  This is a known problem that we have a fix for, but because we came up with the fix after most of the calibration was already done, we decided to wait till the next experiment to implement it.  The root cause is the power supply temperature cycling.  The large dip is when the cooling fan kicks on.  The fix is half hardware to put in less temperature sensitive resistors and half software to put a closed loop control on the voltage control.  Meanwhile, we tolerate it till we think it is clearly worth changing.  This voltage sag is reflected in

Other Things: 

• Don't necessarily believe the excess power calculation, yet.  I would consider it to be still in the noise till we rule out other potential causes of higher temperature readings.
• We have a slight Hydrogen leak.  Unfortunate, but we should be able to tolerate it, though.  

All this data and more are available here.  There are many, many questions that we have not had time to look at, yet.  I mean, who can think of a better way to spend their weekend, right?
