Coming in late on the blank debate.
I have no objection to a blank, but if I only had limited time I'd go
with a longer live-run, particularly if self-sustained.
But if you WANT a blank/dry run, I suggest the following protocol.
1. Rossi prepares the ecat, charged with Nickel and Hydrogen
2. Rossi starts a live run, from empty and cold. The exact pump,
power level and time settings are noted.
3. Rossi discharges the hydrogen, cools it down and drains it. That's
the end of the live run.
4. Rossi purges the core, eg with air or Nitrogen, until there is a
very small chance of hydrogen being left.
He might even do some dummy runs, until he is convinced there is
no excess power.
5. Rossi restarts a blank run, following exactly the same protocols (2 and 3)
6. The equipment is disassembled for inspection. (eg Oct 6)
This avoids any risk of the eCat core being damaged by the dry run.
One load of nickel is only $10.
