Try responding to a real argument: if the claim, as Aussie Guy made it, is for a device with a COP of 5 over an input measured in watts, then why not close the loop? What COP would you need? 10? 100? what? Defkalion, by the way, claims 35x.
As I said elsewhere, it depends on the temperature rise in the cell caused by the PF effect. Depending on how hot the cell operates, a reasonable estimate might be a COP of 30 to make it theoretically possible to close the loop. That's based on a guess that the PF effect warms the cell by 10 degrees C.
In practice the requirement to close the loop with a wet CF cell is likely to be more stringent than that.
Wet CF cells seem to me to be unlikely to ever be good for anything "practical", regardless of how "real" the effect is, due to the poor quality of the heat produced. The gas phase cells, such as the alleged Rossi Roarer, seem to me to be much more likely to eventually evolve into something useful (likelihood that Rossi's a fraud aside).
Defkalion's cells, though they may be made of smoke and mirrors, run sufficiently hot and with a sufficiently high COP to make closing the loop seem feasible. (Since they've never demonstrated anything, it's quite possible that they've already closed the loop, and drive their control hardware using heat from the reaction. After all, we haven't seen their cells in action, so we have no reason to think they don't!)
