Where he is referring to the long time it takes to ramp up the E-Cat's
internal temperature on startup.

 

Mr. Catania, do you realize that the electrical power into the E-Cat's
resistance heater was NOT started at 100%, it was started at a setting of
'5' and RAMPED UP slowly over 40 minutes!  Here is the time progression for
resistance heater power.

 

Timestamp  PLC Setting   DeltaTime (minutes)

---------  -----------   ----------

18:59         5             0

19:10         6            11

19:20         7            10

19:30         8            10

19:40         9            10

 

We know that the 'Setting' is referring to the duty cycle, but we do not
know exactly what the relationship is. since 9 is the MAXimum setting, and
Lewan states 'power was at this point constantly switched on', then a
setting of '9' is presumably a 100% duty cycle. (?)  

 

Since the PLC's are programmable, we cannot assume that a setting of '5' is
50% or 60%; it could even be programmed to be 10% duty cycle. So no useful
calculations OR conclusions can be made during this ramp-up phase.

I think it caused a rise. There is no rise. Its your imagination. The
temperature at power off is too low and must be discarded. If I bring a
piece of metal the size of an E-Cat to some temperature (and note that this
takes considerable time in the ramp up) and then I cut the power, the
temperature will not instantaneously drop. It will stay at the same
temperature and decline slowly. There is much too much mass for what your
talking about to happen. I have to laugh at the fact that if you saw the
temp drop even a hundredth of a degree at power down you would have declared
the thermal inertia regime over and the CF regime to have begun.
