Amazing persistence with consistence by Rossi and unskilled observers, as yet again a flawed demo that provides partial and inadequate evidence and information for settling the issue of whether there is indeed any excess heat or other anomalies...
Naturally, a pragmatic skeptic will consider how the electric heater would be the source of the temperature fluctuations... There needs to be detailed information about the location of the thermister, the actual mass and geometry of the interior of the device, and tests to determine its thermal mass and average heat capacity -- also heat capacity may vary with flow rate, temperature, and pressure -- if the heater heats a local region with substantial mass to temperatures much higher than the 130 deg C (water, steam, both?) outside the local region, then with electric power shut off, that heat in the hot local region will continue to flow into the wider region where the water flows, increasing its temperature a few degrees... so not a heat after death LENR miracle, but just complex thermal inertia... As Spock often noted, human behavior is constantly facinating in the variety of its strangeness...
