Yes, that might be what they need. I am concerned about the calibration used for the earlier Celani publication where a forth order radiation (S_B) assumption was used to calculate the power. The MFMP guys have very clearly demonstrated that this is not happening with their cells. I recently saw something written on their site that suggests that this is still being considered or applied by Celani. If the forth order calculation is used from this point forth, I will question the results until they are proven accurate. To me it is that simple. Use that technique and you will likely experience major errors.
Recently a plan has been put into place to use a calorimeter to measure the excess heat. This is the proper procedure and should settle the issue once properly calibrated. They have found that the wire used by Celani had many more layers than the ones they tested, so things might start looking more reasonable if more can be obtained. The latest I read is that the multi layer wire might not be available. The saga continues.

The curve fit is achieved by using the internal curve fitting routine of Excel in its X-Y chart menu. I am fortunate that it is a quadratic equation that is required and not a higher order. If excess heat were an issue I feel confident that it would impact the calibration accuracy with its non linear behavrior versus temperature becoming evident. The closeness of my calculated input power to the actual is an indication that excess power is not having a large impact. Also, there are enough pairs of points covering enough of the axis to rule out luck in obtaining the proper coefficients. As you know a perfect fit is always possible if only 3 pairs of points is available. We used 8 pairs if I recall correctly. With a setup like the one they're currently using for the USA cell, one wants to see on the order of 10-20 W excess power to have a sense that it is not some threshold effect. So even if we saw evidence for 1-2 W excess power, I doubt this would be convincing for anyone. It would be nice if Celani could find the time to visit the MFMP and help them set their cell up. Eric
