It may be hard to get ro operating temp with only the electric power supply and no LENR.

Would be easy enough to do a second control run even now to add some confidence to the calorimetry. The alumina + wire will be off-the-shelf all someone need do is ask Rossi for specs of tube and wire - he should be happy to provide them in the interests of clarity.
