I don't have time for time stamping but I wanted to throw in my support for this statement

Perhaps the GN particles are the byproduct, rather than the energy source. This would explain why the solar furnaces don't need to ever be refilled.
I can't remember where I originally heard/saw this but the idea that solar furnaces produce GN particles as a by product of their perpetual energy generation process seems familiar. I checked a few Gundam knowledge sources including Gundam Wiki and this idea seems to be supported. GN Particles have lots of awesome applications but I always felt the true goal of Aeolia's theoretical work was in solving energy problems and the generation and practical applications of the spiffy particles were side bonuses to the system he came up with.

Anyway, since Eifman was investigating the properties of GN particles and Trans-Am seems more related to using a lot of GN particles at once than to the energy generation system that produces them I could live with it if the idea that he might have theorized something like if you had lots of these particles and you did X,Y, and Z with them then maybe you could get a big performance boost for your mobile suit for a little while. I doubt any theories he came up with would have been as well thought out as the Trans-Am CB uses since one can assume Aeolia had much more time to think about it but the idea is essentially, use massive amounts of GN particles in some way to increase performance for a short time.
