"Donor#356" has provided some interesting feedback to MFMP, to Robert Greenyer, in his 5/2/16 post #346 that you can read via quantumheat.org, right hand side Cookbook link, down at the very bottom in the comments section.
Related, in the video ME356 provided of the pre- and post-ignition appearance of one of his reactors has anyone else noted the physical "shudder" at the moment just before the visible excess heat begins? Is that from the reactor itself, or hint of some triggering event, I wonder?
