Also we know that the water level was increasing so it is simple to envisage a system where heat transfer from stored heat increases as a result of increasing contact area between water and heat source. And to reiterate heat storage: Graphite can store up to 1.5kWh/kg or nearly 3kWh/l in a vacuum enclosure. 1.5GJ from 50 modules would only require about 16kg or 8 liters per module. There are also a lot of high heat of fusion materials: LiH that requires about 1.6kWh/kg to heat from room temp to melt at 960K (~1.3kWh/L) Silicon metal that releases 0.8kWh/kg to heat up and melt at 1700K (~1.9kWh/l) LiF that releases 0.6Wh/kg heating to melt at 1120K (~1.5kWh/L). Which is why Rossi needs to do a much higher standard of demo - he certainly hasn't produced results good enough to remove all doubt about fraud. Not that I believe Rossi is a total fraud, but I am fairly convinced that he is hiding some short-fall in performance (eg reaction duration or exaggerating power level) or he wouldn't have any reason to be so furtive in his demos. Interesting chat tonight with a professional energy trader who worked for one of the big international oil trading firms. He said that they were aware of Rossi, but after investigation regarded the likelihood of it being real as 0% - and that their trading would have been massively affected by even a 1% chance of it being real.
