Regarding radiation: The Minnesota team is using a fused quartz tube. Since Quartz glass is more transparent to the infrared wavelengths than borosilicate glass, the cell is losing a significant amount of the heat energy compared to Celani because Celani is using a borosilicate tube.

Its a matter only of a few percent. If the MFMP team changes the quartz tube to a borosilicate tube (or even better SS tube paint in black), then the question will be solved. Celani doesnt have this problem. Its not a bad news in itself. It is just an evolution/reflexion in their quest for the replication of Celanis effect. Arnaud _____ From: Jeff Berkowitz [mailto:[email protected]] Sent: dimanche 2 décembre 2012 08:02 To: [email protected] Subject: [Vo]:Important news from HUG team in Minnesota It's bad news, but it's important. In short, the contention now is that Celani did not account for effect of pressure changes within the cell. Reducing the gas pressure reduces the thermal conductivity of the gas. This reduces the temperature of cell components like the metal flanges that are mostly heated by the gas. So at lower gas pressure, the flanges don't get as hot and so don't radiate away as much heat. But the electrical heating is constant, so measured temperatures at other points in the cell must rise. HUG is contending that this pressure-modulated rise in temperature elsewhere in the cell is what Celani measured as excess heat. http://www.quantumheat.org/index.php/follow/163-a-partial-explaination Jeff
