The data on the posters show excess heat from 700 to 1000C, growing fast but not regularly at the beginning.
The calorimeter looks like advanced flow calorimeters. thers are two vacuum chambers (the sample soom, and an outside chamber). the ousode chamber is cooled by a flow of coolant whose temperature in and out are mesured... this cooland is insulated outside of course.
This marche the description of Jean-Paul Biberina about his calorimeter, very sensible, even is not accepting huge temperatures.
I cannot interpret this resulst as just interesting, or realy fantastic, but it is at least a positive result.
This will be interesting to ask more question during the poster session.
