"Celani said that on Monday. That was his somewhat arbitrary definition of self-sustaining, during his talk. However, Levi et al. mentioned that the machine self-sustained completely, with no power, for about 15 minutes. No power and no way to turn it off. They exhausted the hydrogen, filled it with nitrogen, and turned up the cooling water flow." Levi describes this in his report, but there he doesn't mention the nitrogen; only that the hydrogen was closed, and 15 minutes later, the cooling water flow rate was increased. But the temperature remaining at 100C for 15 minutes is not evidence that the reaction is continuing. In test 1, it seems like they actually heated the conduit (and whatever infrastructure) to above the temperature needed to produce boiling. Judging by the temperature gradient just before boiling, they could easily have reached twice the power necessary for boiling. That's still far short of what's needed for dry steam, but more than enough to keep the temperature of the expelled fluid at boiling for some time after the power is shut down.
