Running on the Celani Wire

As of 8:45 am US Central Time, we are starting to run current through the Celani wire.  We describe it as "going live" with the experiment.

We will be ramping up the voltage in the same steps that we tested the impedance of the loaded wire at last night.  Every 45 minutes we will increase the power.  We will be watching the t_rise over the time for each step, in addition to all the other stuff.  In all the calibration runs 45 minutes was plenty of time to come to equilibrium.  

The re-warming step

That re-heating mini experiment yielded some pretty interesting stuff.  The resistance hit a new low after cooling after this.  Notice the resistance rises slowly on the first several steps.  On the last 3 steps we see the resistance dropping, probably indicating additional absorption at the higher temps.  By the time it cooled off, the wire was at 14.25 ohms, a new low.  That corresponds to a R/R0 of 0.77!

Additional Clarification:

I want to specifically thank Francesco Celani for the suggestions and support. It was Celani who suggested the Cool down experiment done yesterday.

We'll post new data as soon as we see anything.
